abstract = {Plants are associated with microbial communities, which are inherited through the seed and acquired from the environment. These microbiomes influence plant physiology, chemistry, and functioning. Yet, we lack insights into how seed origin and the environmental microbiome jointly influence the leaf metabolome. We used untargeted metabolomics (gas chromatography/mass spectrometry) on leaves of pedunculate oak (Quercus robur) seedlings to examine metabolic responses to different seed origins and environmental microbiomes, as well as home and away environments. For this, acorns were collected from three mother trees and grown in a multifactorial design with soil and canopy microbiomes originating from the local mother tree (i.e., the home treatment) and neighbouring trees (i.e., the away treatment). We also measured two plant traits-plant height and leaf chlorophyll content-to examine relationships between plant traits and the metabolome. The leaf metabolome did not differ significantly between plants growing with different soil and canopy microbiomes. However, the leaf metabolome differed among acorn origins and between seedlings growing in home vs. away treatments. We found no clear link between plant traits and the leaf metabolome. This study is one of the first to disentangle the combined effects of seed origin and environmental microbiomes on plant leaf chemistry, and the home vs. away framework provides novel insights into local adaptation effects on plant metabolomes within forest ecosystems. These findings have practical implications for the use of local genotypes and the development of microorganism-based management practices in sustainable forestry and agriculture.},

abstract = {Climate change is projected to raise sea surface temperatures and intensify diurnal temperature fluctuations (DTF), threatening the survival of both scleractinian corals and octocorals. Litophyton, a common octocoral in Taiwan's shallow reefs, is frequently exposed to large DTF and summer heat stress, making it a suitable model to study thermal resilience. Coral-associated bacterial communities are known to shift under thermal stress, and key bacterial taxa may play crucial roles in host acclimation. This study aimed to address two questions: (1) Can higher DTF mitigate cumulative heat stress in octocorals? (2) If so, what physiological and microbial community changes accompany this effect? To answer these questions, we conducted tank experiments under constant warming and two short-term DTF regimes (± 5 °C and ± 7 °C; baseline 25-27.8 °C), along with a no-fluctuation control. We measured physiological stress indicators, including superoxide dismutase (SOD) and catalase (CAT) activities, and monitored bacterial community dynamics. Our results show that DTF helped maintain stable photosynthetic efficiency (Fv/Fm) compared to constant warming. Notably, significant differences in ROS activity were only observed in the ± 5 °C group, rather than in the larger ± 7 °C group, indicating a measurable alleviation of thermal stress and greater plasticity in Litophyton coping with temperature changes. Moreover, 29.4% more significantly abundant in the ± 7 °C group compared to the control in the core microbiome Endozoicomonas preceded detectable physiological changes in the host, suggesting a potential role in early stress mitigation. These findings deepen our understanding of octocoral holobiont resilience under fluctuating thermal regimes and highlight Endozoicomonas diversity as a potential indicator of Litophyton health.},

abstract = {Antimicrobial resistance (AMR) poses a major global health challenge, particularly in intestinal infections where the efficacy of conventional antibiotics is rapidly declining. The rising prevalence of antibiotic-resistant pathogens underscores the urgent need for alternative antimicrobial agents with favorable activity profiles. This study evaluated the antibacterial potential of bioactive anthraquinones isolated from Cassia tora L. seeds against clinically relevant intestinal pathogens and probiotic bacteria. Five key anthraquinones, rhein, physcion, anthraquinone-2-carboxylic acid, emodin, and aloe-emodin, were identified and tested for their antibacterial activity. The anthraquinone metabolites exhibited strong antibacterial activity against pathogenic bacteria (Escherichia coli, Staphylococcus aureus, Clostridium difficile, etc.), while showing moderate to relatively lower inhibitory effects against beneficial probiotic strains such as Clostridium butyricum, Bifidobacterium bifidum, and Lactobacillus casei. The MIC profiles indicate relative or modest selectivity toward pathogens, rather than a complete sparing of probiotic species. Molecular docking analysis revealed that these metabolites bind favorably to key bacterial resistance proteins, often surpassing ciprofloxacin in binding affinity, supporting their observed antibacterial activity. Together, these results suggest that C. tora anthraquinones preferentially inhibit intestinal pathogens, maintaining a comparative margin of safety for beneficial gut flora. Anthraquinones isolated from C. tora seeds exhibit potent antibacterial activity toward pathogenic intestinal bacteria and relatively reduced activity against probiotic strains, reflecting selective preference in intestinal bacteria. These findings support their potential as natural antimicrobial candidates for managing intestinal infections and contributing to AMR mitigation. Nonetheless, the measurable inhibitory effects on probiotic species emphasize the need for careful dose optimization and microbiome-conscious therapeutic strategies. Further studies focusing on the mechanism of action, pharmacokinetics, toxicity, and in vivo efficacy are required to evaluate their clinical applicability.},

We highlight key components of the immune system that contribute to clearance of phages in vivo and examine how various factors- including patient-specific variables, treatment regimens and phage characteristics can influence immune responses and, consequently, phage pharmacokinetics during therapy. A clearer understanding of human immune responses to phages is urgently needed to inform the development of more targeted and effective personalised phage therapies - an essential step in combating the escalating threat of antimicrobial resistance.},

Together, these factors have reshaped the current understanding of cancer immunity and systemic therapies, particularly targeted treatments and immune checkpoint inhibitors that act on cancer cells, blood vessels and immune cells within the tumor microenvironment (TME). Among these, the presence of bacteria within tumors has emerged as a critical modulator of the TME, influencing tumor progression and antitumor responses across various cancer types. With the rapid expansion of cancer immunotherapies, advanced detection and sequencing technologies are increasingly applied to elucidate interactions between intratumoral microbiota and immune cells. The present review focuses on the mechanisms by which tumor bacteria modulate immune responses, supported by validations from in vitro and in vivo studies. The potential of intratumoral microbiota as biomarkers for prognosis and immunotherapy response is also discussed, alongside emerging biotechnological tools for microbiota profiling. By examining the dual roles of intratumoral microbiota in cancer biology, the current review provides a comprehensive overview of their implications and practical applications in cancer‑related research.},

abstract = {Inflammatory bowel disease (IBD) encompasses chronic or relapsing inflammation within different regions of the gastrointestinal tract. Pentoxifylline (PTX), a methylxanthine derivative primarily used to improve blood flow in peripheral vascular diseases, has demonstrated anti-inflammatory and immunomodulatory properties, suggesting its potential in attenuating IBD-associated inflammation. However, its clinical application in IBD remains limited, partly due to its short half-life and poor targeting to inflamed intestinal tissues, necessitating strategies to enhance its bioavailability and tissue-specific delivery. To address this limitation, we developed a targeted drug delivery system utilizing a microfluidic approach to fabricate pH-responsive core-shell hydrogel microcapsules encapsulating PTX, referred to as PTX-loaded hydrogel microcapsules (PHM), for enhanced delivery to inflamed colonic tissue. These microcapsules were generated via photopolymerization of triple emulsion droplets, resulting in a structure composed of a poly (acrylic acid)-poly (ethylene glycol) diacrylate (PAA-PEGDA) shell and a PEGDA core, separated by a thin oil layer. The oil layer serves as a protective barrier against the acidic gastric environment, while the pH-responsive swelling of the PAA-PEGDA shell at basic pH (7.5) compresses and destabilizes the oil layer, thereby enabling controlled PTX release specifically in the colonic environment. In vivo studies using dextran sulfate sodium (DSS)-induced IBD in ICR mice demonstrate that PHM significantly mitigates disease severity, as evidenced by an approximately 38.5% reduction in disease activity index scores, restoration of mucosal architecture, and decreased infiltration of colonic macrophages. In parallel, PHM treatment markedly suppresses colonic inflammatory responses, lowering IL-1β by 40%, IL-6 by 66.2%, and TNF-α by 36.2% compared to DSS-treated mice, along with a broader reduction of pro-inflammatory mediators, highlighting its anti-inflammatory potential. Notably, PHM also contributes to the rebalancing of dysbiotic gut microbiota, including the restoration of beneficial genera such as Bacteroides acidifaciens and PAC001120_s, thereby promoting microbial homeostasis. Collectively, these findings underscore PHM as a promising PTX-based therapeutic strategy for effective IBD intervention.},

abstract = {INTRODUCTION: Proton pump inhibitor (PPI) use has been associated with reduced immune checkpoint inhibitor (ICI) efficacy in metastatic non-small cell lung cancer (mNSCLC) with evidence limited to their use during a short time period around ICI initiation. This study evaluated the associations between the timing and intensity of PPI exposure up to one year before ICI initiation and overall survival (OS) in mNSCLC patients treated with ICIs.

METHODS: This retrospective cohort study included consecutive mNSCLC patients treated with ICIs within routine clinical practice. Patients were grouped by the timing of PPI exposure from 365 days before to 30 days after (-365 to +30 days) ICI initiation: (1) no PPIs within -365 to +30 days; (2) PPIs only within -365 to -31 days; and (3) PPIs also within ±30 days of ICI initiation. The intensity of PPI exposure was quantified with the total defined daily doses (DDDs). OS was estimated using Kaplan-Meier methods, and associations between PPI exposure and OS were analyzed using Cox proportional hazards models.

RESULTS: Of 391 patients included (median age 64.7 years, 58.6% male), 73.4% had access to PPI within -365 to +30 days of ICI initiation. PPI exposure within ±30 days (220 patients) was associated with reduced median OS (mOS) compared with no PPI exposure between -365 and +30 days of ICI initiation (mOS 15.4 vs 21.9 months; adjusted hazard ratio [aHR] 1.373, 95% CI 1.007-1.873, p = 0.045). High-intensity PPI exposure within -365 to +30 days of ICI initiation (DDD > 159; 108 patients) was also associated with reduced mOS compared with no PPI exposure in this period (mOS 13.4 vs 21.9 months; aHR 1.454, 95% CI 1.023-2.067, p = 0.037).

DISCUSSION: PPI use around ICI initiation as well as PPI treatment intensity over a wider period was associated with reduced OS. Efforts should be made to streamline PPI use.},

Microbiome shifts in AD suggest that microbiota could modulate the disease. We therefore sought to identify skin bacteria that attenuate S. aureus-induced IL-33/TSLP release from keratinocytes. Micrococcus luteus was unique among skin isolates in its ability to negate cytokine induction. The bioactive factor responsible was identified using fractionation, LC-MS and recombinant proteins, as the serine protease "PA domain protein" (PADP). Immunoblotting and ELISA confirmed Sbi and IL-33 degradation by PADP. This was not observed with the M. luteus type strain which contains a frame shift mutation within the PADP active site. These data provide new insights into the role of skin microbiota in AD and highlights their potential as topical therapeutics.},

Due to pooled fecal sampling (n=1 composite library per group), microbiome results represent descriptive trends in diversity and composition. BCP was associated with discernible shifts in gut microbiota, including increased abundances of beneficial genera, such as Akkermansia, Lactobacillus, and Allobaculum, and the Muribaculaceae family. PICRUSt2 functional analysis suggested an enrichment in secondary metabolite biosynthesis, vitamin (e.g., retinol) metabolism, and xenobiotic biodegradation pathways. Furthermore, BCP was associated with significantly higher levels of activated hepatic AMP-activated protein kinase (AMPK), a key energy metabolism regulator, compared to control groups. Although microbiome findings are descriptive due to the study design, these results suggest BCP as a potential dietary intervention to help mitigate age-related metabolic decline and promote healthy ageing.},

However, due to the heterogeneous effects of intratumoral microbes, designing treatments tailored to the unique microecological characteristics of individual tumors poses a significant challenge. Here, we found significant variations in the abundance of five bacterial genera-Lysinibacillus, Stenotrophomonas, Weissella, Comamonas, and Aeromonas-between lung adenocarcinoma (LUAD) and normal tissues by analyzing single-cell transcriptomic datasets. These specific bacterial clusters were significantly associated with immune infiltrates in the tumor microenvironment (TME). After confirming their effects in mouse models, these bacterial taxa were identified as potential therapeutic targets. Through in vitro drug screening assays, berberine was identified as a promising agent that selectively inhibits harmful bacteria while sparing beneficial ones. To address berberine's low solubility and tumor targeting issues, it was encapsulated into tumor cell-derived extracellular vesicles (EV-ber). Feature analysis demonstrated that EV-ber shifted the intratumoral microbiome profile toward an anti-tumor phenotype and enhanced anti-tumor immunity in the TME. Furthermore, EV-ber administration inhibited LUAD growth, impaired LUAD metastatic ability, and boosted the effectiveness of anti-PD-L1 immunotherapy in mouse models. In conclusion, this work demonstrates the potential of personalized intratumoral microbial re-education strategies in LUAD therapy.},

As the Han and Uygur ethnic groups represent the predominant demographics in Xinjiang, this follow-up study focuses on identifying characteristic gut microbial alterations in Han patients with active tuberculosis (TB) and those with latent tuberculosis infection (LTBI). The findings are expected to support tailored strategies for the regional prevention and control of tuberculosis.

METHODS: A total of 51 cases of TB, 35 cases of LTBI and 51 healthy controls (HC) were recruited from the Infectious Disease Hospital of Xinjiang Uygur Autonomous Region. Fecal samples were collected and underwent 16S rRNA gene sequencing.

RESULTS: The gut microbiota α diversity was significantly lower in the TB group compared to the LTBI and HC groups, with significant β diversity differences observed among all three groups. At the phylum level, Firmicutes was the most abundant in all groups. The most abundant genera in the TB, LTBI, and HC groups were Phocaeicola, Escherichia, and Bifidobacterium, respectively. Lefse analysis revealed that pro-inflammatory and opportunistic pathogenic genera were enriched in the TB group, whereas butyrate-producing and immune-modulating genera dominated the LTBI group. PICRUSt2 analysis identified only five differential metabolic pathways between the TB and HC groups, among which Clostridium showed the strongest positive correlation with PWY-6876 (R = 0.79, P < 0.01).

CONCLUSIONS: This study clarified the diversity, microbial species composition profiles, and metabolic pathways of the gut microbiota in the Han population with different TB states in the Xinjiang region of China. These findings may provide a certain theoretical basis and reference for the precise prevention and control of TB in Xinjiang.},

abstract = {The oral microbiome functions as an intricate and coordinated microbial network, residing throughout the oral cavity in both health and disease. Although most oral microbiome research has focused on bacteria, there is a growing interest in oral fungal communities, known as the oral mycobiome. The oral cavity hosts a complex and diverse mycobiome comprising of an estimated 100 fungal species; however, the roles of these fungi have been largely overlooked and remain insufficiently characterized, particularly in children. This represents a critical gap, as early life is a key window for establishing oral microbial communities that shape lifelong oral and systemic health and offer opportunities for early intervention. Recent technological advances, especially next-generation sequencing, have enabled the identification of new fungal species and deepened our understanding of the diversity, structure, and interactions among fungal, bacterial, and other components within the oral cavity. Yet, research on the pediatric oral mycobiome remains fragmented and limited in scope. Addressing this gap is important since the early-life oral mycobiome may play an underappreciated role in shaping immune development, influencing susceptibility to oral diseases, and potentially contributing to systemic conditions during childhood and beyond. In this review, we examine the oral mycobiome in children, focusing on its formation and dynamics in health and in disease, including dental caries, periodontal disease, endodontic infection, and cleft lip/palate, and exploring its connections to several systemic consequences. By synthesizing current findings on fungal-related biological risk factors, we aim to inform the development of improved diagnostic tools and to guide the advancement of preventive and therapeutic strategies from fungal perspective.},

Skin biopsies offer a promising alternative to whole-animal collection and other minimally invasive approaches; however, systematic evaluations of recovery and impacts on body condition remain limited. Here, we assess the effects of small (2-mm) dorsal skin biopsies in four frog species, including three highly endangered Harlequin frogs (Atelopus bomolochos , A. balios , A. longirostris) and the Gualataco marsupial frog (Gastrotheca riobambae). Under controlled laboratory conditions and in semi-natural enclosures, we monitored wound healing, survival, and body mass trajectories in biopsied and control individuals over a one-month period. Across all species, biopsy sites fully healed within approximately three weeks, following consistent stages of re-epithelialization and subsequent repigmentation. No biopsy-related mortality was observed, and body mass did not differ between biopsied and control individuals, indicating no detectable effects of skin biopsies on body condition during the wound-healing period. Occasional minor post-biopsy reactions resolved without intervention within the observation period. We additionally report anecdotal field recovery observations for three other species (A. coynei , A. laetissimus , and A. sp. aff. longirostris), indicating survival and visible wound closure following release. Together, these results indicate that small dorsal skin biopsies represent a safe, non-lethal sampling method for amphibians, including highly endangered taxa.

abstract = {INTRODUCTION: Obesity-related diabetes is a significant global health concern, underscored by perturbations in iron metabolism and gut microbiota composition. This study investigates the mechanistic role of Chia Seed Oil (CSO), rich in omega-3 fatty acids, in suppressing iron metabolism pathologies and promoting gut microbiota alterations to mitigate obesity-related diabetes.

METHODS: Using a high-fat diet-induced obesity model in male C57BL/6J mice, we aimed to explore the effects of CSO supplementation on metabolic outcomes, iron status, and gut microbiota diversity.

RESULTS: Our findings suggest that CSO effectively regulates iron metabolism, evidenced by altered serum ferritin levels, hepcidin, and transferrin saturation, while promoting a diverse gut microbiota profile.

DISCUSSION: The study elucidates the potential of CSO as a therapeutic agent in managing obesity-associated metabolic disorders by restoring iron homeostasis and fostering gut health. These results highlight the interconnectedness of dietary fat, iron metabolism, and microbiome dynamics in the pathophysiology of obesity-related diabetes, suggesting a multifaceted approach to treatment strategies.},

abstract = {INTRODUCTION: The Kabru Glacier, located in the Sikkim Himalayan region at an altitude of 7,318-7,412 m above sea level (a.s.l), forms part of the Kanchenjunga range in the Eastern Himalaya. Glaciers in this region are predominantly summer-fed and highly sensitive to climatic fluctuations. Despite their ecological significance, glaciers of the Sikkim Himalaya remain largely unexplored from a microbiological perspective due to harsh weather conditions and limited accessibility. In this context, the present study investigates the bacterial diversity across different depths (upper, middle, and bottom) of ice core samples collected from the Kabru Glacier.

METHODS: Bacterial diversity was examined using a combination of culture-dependent and culture-independent approaches. In addition, antibiotic resistance profiles and metal tolerance characteristics of the isolated bacteria were evaluated to gain further insight into their adaptive potential.

RESULTS AND DISCUSSION: Culture-dependent analysis revealed a comparatively high bacterial load in the Kabru Glacier, suggesting that the biodiversity-rich Himalayan surroundings may influence the microbial community structure. Phenotypic characterization showed a predominance of Gram-positive bacteria (62.6%) over Gram-negative bacteria (37.3%). Growth profile analyses indicated optimal growth temperatures of 15°C and 20°C, with variable tolerance to salinity and pH, reflecting adaptive responses to environmental stress. Elemental analysis of ice core samples revealed higher concentrations (ppb range) of Na, Mg, K, Ca, Mn, Li, and Zn compared to other elements. Phylogenetic analysis based on 16S rRNA gene sequencing identified members of the phyla Pseudomonadota, Bacillota, and Actinomycetota. Consistently, culture-independent 16S rRNA amplicon sequencing also demonstrated the dominance of these phyla. Alpha diversity indices corroborated trends observed in the culture-dependent analysis, supporting the complementary reliability of both methodologies in elucidating bacterial community structure. Furthermore, antibiotic susceptibility testing revealed resistance to cefixime (CFM) and metronidazole (MET), along with elevated tolerance to heavy metals such as CuSO4, ZnCl2, and NiCl2, while showing lower tolerance to HgCl2.

CONCLUSION: Collectively, these findings suggest that bacterial diversity in the Kabru Glacier is shaped by multiple environmental parameters. The occurrence of antibiotic-resistant and metal-tolerant bacteria underscores the need for further comprehensive investigations to better understand microbial adaptation and potential ecological implications in high-altitude glacial ecosystems.},

abstract = {INTRODUCTION: The anticancer drug camptothecin (CPT) has limited clinical applications due to severe toxic reactions.

METHODS: We combined CPT with PHBVHHx (PHA) nanoparticles by a modified emulsion method for the first time construct a novel nanomedical drug (CPT-PHA-NPs, CPNs).

RESULTS: In vitro experiments verified the drug loading level (89%), sustained-release properties (40% release within 48 h; near-complete release over 21 days), and inhibition ability of the compound on HT-29 cell activity (IC50 = 0.44 μM). In vivo, CPN-treated mice showed significantly less body weight reduction (P < 0.05 from day 7) and markedly improved liver and kidney function markers compared to controls. Histological analysis confirmed that CPN effectively prevented hepatocyte necrosis and renal inflammation observed with free CPT, demonstrating higher biosafety and lower toxicity. Crucially, 16S rRNA sequencing revealed that CPT severely depleted probiotics (Akkermansia, Lactobacillus, Candidatus_Arthromitus, and Bacilli_unclassified) while promoting pathogenic taxa (Lachnospiraceae_NK4A136_group, [Eubacterium]_xylanophilum_group, and Faecalibaculum), whereas CPNs attenuated these microbial disruptions. Metabolomics further showed CPNs' milder effects on phenylalanine and essential amino acid metabolism vs. CPT.

DISCUSSION: In conclusion, this novel type of nanomaterial not only possesses excellent performance but also can reduce the impact of CPT on tissues, intestinal flora and serum metabolism, providing a new strategy for anti-tumor treatment that takes into account both microbial homeostasis and metabolic safety.},

abstract = {The composition and function of animal gut microbiota are influenced by various intrinsic and extrinsic factors. Hibernation represents a significant physiological challenge for heterothermic mammals, yet the effects on gut microbiota in bats remain understudied. This study investigated seasonal variations in the gut microbiota of Rhinolophus sinicus between summer activity and winter hibernation using 16S rRNA gene sequencing (n = 12 per group). Sequencing analysis identified 907 ASVs in the hibernation group and 555 ASVs in the summer group, with only 27 ASVs shared between groups, suggesting substantial seasonal turnover in microbial community membership. At the phylum level, Pseudomonadota (formerly Proteobacteria) dominated the gut microbiota, but no significant difference was found between seasons (77.52% during hibernation vs. 57.15% during summer). Bacillota (formerly Firmicutes) decreased significantly, while Actinomycetota (formerly Actinobacteriota) increased significantly in the hibernation group compared to the summer group. Genus-level composition exhibited seasonal variation, with distinct microbial communities characterizing each period. Alpha diversity analysis revealed significant differences in Faith's phylogenetic diversity between seasons, suggesting shifts in phylogenetic composition, while Chao1, Shannon, and Simpson indices remained unchanged. Beta diversity analyses revealed significant structural divergence between seasonal groups. Functional prediction using PICRUSt2 suggested seasonal shifts in metabolism-related pathways, with putative enrichment of lipid metabolism and xenobiotic biodegradation pathways during hibernation, while carbohydrate metabolism appeared more prominent during the active period. These findings suggest that winter fasting may alter intestinal microbial metabolic functions, potentially shifting the microbiota from carbohydrate-oriented to lipid-oriented metabolism. This study enhances our understanding of host-microbiome crosstalk in hibernating mammals and highlights the potential adaptive role of gut microbes in facilitating survival under extreme physiological conditions.},

abstract = {INTRODUCTION: Insulin resistance (IR) is central to type 2 diabetes mellitus (T2DM). Composite indices including the atherogenic index of plasma (AIP), metabolic score for insulin resistance (METS-IR), triglyceride-glucose index (TyG), and TyG-BMI, are widely used to quantify IR severity. The gut microbiome (GM) has been implicated in metabolic dysregulation, but its associations with IR remain incompletely defined.

METHODS: We collected blood test results and stool samples from participants with T2DM and healthy controls. Stool samples underwent 16S rRNA gene sequencing. We trained XGBoost models to distinguish individuals with higher IR from healthy controls based on GM profiles and performed correlation analyses between GM features, clinical measures, and IR indices.

RESULTS: Triglycerides (TG), fasting blood glucose (FBG), and high-density lipoprotein cholesterol (HDL-C) differed significantly between the T2DM and control groups. IR indices (AIP, METS-IR, TyG, and TyG-BMI) were markedly higher in the T2DM group. XGBoost models based on GM profiles showed high discriminatory performance for identifying T2DM individuals with higher IR, with Bacteroides and Faecalibacterium contributing most to model performance. Correlation analyses further indicated that Lachnospiraceae_UCG-010, Bacteroides, Faecalibacterium, Lachnospira, Parasutterella, and Escherichia-Shigella were associated with clinical measures and IR indices.

CONCLUSIONS: Specific GM features are associated with IR-related clinical measures and composite indices in T2DM, supporting their potential as intervention targets to improve insulin resistance and restore carbohydrate and lipid metabolism.},

abstract = {Nontuberculous mycobacteria (NTM) are ubiquitous bacteria that cause a spectrum of diseases, most notably pulmonary disease (NTMPD). The host factors contributing to the heightened susceptibility and severity of NTMPD in elderly individuals are poorly understood. Prior studies have reported increased incidence of NTMPD in individuals receiving immune modulatory biologics such as anti-TNF and JAK-STAT inhibitors. Moreover, we recently described that age-related changes in the lung microbiome, notably the loss of a main commensal Tropheryma species, may contribute to increased severity. Therefore, in this study we explore the hypothesis that TNF-inhibition and a disrupted lung microbiome are key factors that contribute to worse disease outcomes in older NTMPD patients. Young (4-6 years old) rhesus macaques were pretreated with nebulized amikacin and vancomycin to deplete the lung microbiome, pretreated with the TNF inhibitor Inflectra or left untreated. Animals were subsequently inoculated with M. avium subsp. hominissuis (MAH) in the right lung. Bacterial load, radiographic changes, immune responses, and microbiome composition were monitored longitudinally. Antibiotic-treated animals experienced significant dysbiosis including the depletion of Tropheryma from the lung microbiome. One antibiotic-treated animal developed and resolved cavitary disease after the lung microbiome returned to homeostasis. Inflectra-treated animals favored an acute-phase response that persisted up to 114 days after inoculation and one Inflectra-treated animal developed chronic granulomatous disease. No control animals showed granulomas. These data suggest that lung microbiome dysbiosis and TNF inhibition can increase susceptibility to NTM granulomatous disease.},

abstract = {BACKGROUND: Diabetic foot osteomyelitis (DFO) is a serious complication of diabetes and a leading cause of lower-limb amputations. Conventional culture-based diagnostics often underestimate the microbial diversity of infected bone tissue. This study represents the first characterization of both total and ribosomally active bone microbiota in Hispanic patients with DFO using high-throughput 16S rRNA gene sequencing. The work aims to contribute to the inclusion of underrepresented populations in microbiome research and informing molecular-based antimicrobial strategies.

METHODS: Bone specimens (n = 13) were collected from seven Chilean patients with histologically confirmed DFO. Samples were analyzed using conventional aerobic culture and 16S rRNA gene sequencing from both genomic DNA (gDNA) and complementary DNA (cDNA) to characterize the total bacterial community and the ribosomally active fraction. In three patients, samples were stratified by bone depth (superficial/top, middle and bottom). Microbial diversity and relative abundance were assessed across patients and bone layers.

RESULTS: Acute osteomyelitis was the predominant histopathological pattern. Culture yielded 19 bacterial isolates, 95% of which were Gram-negative bacilli. Sequencing identified 3,412 operational taxonomic units (OTUs), with Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria as dominant phyla. Enterobacteriaceae and Enterococcaceae were the most ribosomally active families. Microbial community composition varied substantially among patients and across bone depths. Staphylococcus aureus was infrequent (5% of culture isolates; ~1% of sequence reads), whereas low-abundance but ribosomally active taxa, such as Corynebacteriaceae, were consistently detected across all layers.

DISCUSSION: This combined metagenomic and ribosomal transcript analysis reveals a polymicrobial, patient-specific bone microbiota in Chilean patients with DFO, highlighting potentially active bacteria frequently overlooked by standard diagnostic methods. These findings underscore the value of integrating molecular approaches into clinical workflows to improve pathogen detection and support more personalized antimicrobial strategies, while also helping to address gaps in microbiome research among underrepresented populations.},

This review offers an in-depth evaluation of the prevalence, pathways, and risks associated with MPs in meat and dairy products, which are significant global sources of animal-based nutrition. Data from different countries shows a persistent presence of MP contamination in livestock tissues, poultry organs, processed meat products, raw milk, and commercial dairy items, with identified polymer types such as polyethylene, polypropylene, polystyrene, nylon, PET, and regenerated cellulose. MPs are primarily found in the form of fibers, fragments, films, and irregular particles, with sizes varying from less than 10 μm to several millimeters. Their concentrations can range from a few particles per gram in raw meat to over 30,000 MP/kg in processed products, and from several MPs per liter in raw milk to more than 1800 MP/kg in cheese. Contamination occurs at various points along the farm-to-fork continuum, encompassing ingestion via tainted feed and water, interaction with agricultural plastics, transfer from milking and processing apparatus, wear during cutting and grinding, and leaching from packaging materials. Recent toxicological findings indicate that MPs and their related chemical additives could lead to gastrointestinal inflammation, oxidative stress, endocrine disruption, immunomodulation, and microbiome dysbiosis, although the long-term health effects are still not fully comprehended. Inconsistencies in methodology related to sampling, particle extraction, and spectroscopic identification impede precise comparisons of exposure and assessments of risk. The review points out significant gaps in current studies and emphasizes the necessity for uniform analytical techniques, enhanced waste and plastic management, as well as sustainable processing and packaging approaches to reduce the entry of MPs into animal-derived foods.},

Here, we investigated the effect of Biocidin[®], a botanical supplement, on biofilms of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Candida albicans. A single (bolus) dose of Biocidin[®] resulted in a significant decrease (> 2 Log) of biofilm and planktonic populations, while a 24-h continuous dose of 25% and 50% Biocidin[®] led to a typical biphasic killing curve, with the latter concentration resulting in biofilm eradication of P. aeruginosa, S. aureus, and E. coli. Exposure to sub-inhibitory concentrations of Biocidin[®] did not affect biofilm viability. Results from this work have implications for the use of Biocidin[®] as a treatment for biofilm-associated infections and as a supplement in natural medicine.},

However, the role of urinary microbiota and their associated OMVs proteins in the metastatic processes of bladder cancer (BCa) remains insufficiently understood. In this study, we investigated the impact of urinary microbiota on BCa progression and identified potential biomarkers within the urinary microbiome. We identified Fusobacterium nucleatum (F. nucleatum) as a predominant member of the urinary microbiota. Proteomic analysis of F. nucleatum OMVs revealed the outer membrane protein FomA as the most abundant component. A FomA-deficient F. nucleatum mutant strain was generated to assess the relationship between FomA and lymph node (LN) metastasis. Mechanistically, FomA-containing OMVs directly engage Toll-like receptor 2 (TLR2), triggering the NF-κB signaling pathway and upregulating interleukin-6 (IL-6) expression. Elevated IL-6 induces M2b macrophage polarization, which subsequently promotes the release of VEGF-C to facilitate LN metastasis. Furthermore, we identified pinocembrin, a natural flavonoid, as a potent inhibitor of the FomA-TLR2 interaction, effectively suppressing BCa progression. Collectively, our findings uncover a previously unrecognized microbiota-driven mechanism by which F. nucleatum-derived OMVs reprogram the tumor immune microenvironment toward a pro-metastatic state and highlight FomA as a promising therapeutic target.},

Ammonia stress was applied from days 28 to 56. The results showed that intestinal histological damage was alleviated in the L and M groups under ammonia stress. In the M group, the levels of total antioxidant capacity and Nrf2, HO-1 and Occludin were the highest. Regarding ferroptosis-related genes, DMT1, FTM and FPN1 exhibited their highest expression in the L group, while TF, TFR1, FTL, SLC7A11 and GPX4 showed their highest expression in the M group. FTH demonstrated its highest expression in the H group. Furthermore, the expression of ACSL4 in the L and M groups was significantly lower than that in the C group. Intestinal microbiome analysis revealed enhanced microbial diversity in the tea polyphenol-added groups, accompanied by reduced relative abundance of dominant phylum Fusobacteriota and genus Cetobacterium compared to the C group. These results suggested that dietary supplementation of 200-400 mg kg[-1] tea polyphenols could alleviate ammonia-induced intestinal ferroptosis and histological damage, as well as protect intestinal health by regulating the compositional structure and diversity of the intestinal microflora. Specifically, the 400 mg kg[-1] dose exerted the most comprehensive protective effects.

Given its small genome size and high tolerance to abiotic stresses, such as drought, salt-alkali, and heat, it has become an ideal crop model for abiotic stress research. This review synthesizes recent advances in sorghum genomics, including the development of gapless reference genomes, pan-genome analyses revealing extensive structural variation, and population resequencing studies that have uncovered domestication signatures and stress adaptation loci. Moreover, we summarize progress in sorghum genetic resource collection, selection strategies, and breeding improvement. Genetic functional studies have identified key genes regulating yield-related traits, quality attributes, and tolerance to abiotic/biotic stresses. In molecular breeding, notable achievements include the establishment of efficient transformation systems, CRISPR/Cas9-mediated gene editing enhanced by morphogenic regulators, and mutagenized populations for gene function validation. Notably, challenges persist, such as the functional characterization of complex quantitative traits, integration of multi-omics datasets, and genotype-dependent transformation efficiency. Future research directions emphasize the utilization of wild germplasm, in-depth structural variation analysis, population-level transcriptomics, exploration of microbiome-plant interactions, and AI-driven intelligent breeding approaches. These strategies aim to engineer climate-resilient sorghum varieties to ensure global food security and promote sustainable bioenergy production.},

While rhizobia remain the central actors in this symbiosis, recent discoveries reveal the presence of non-rhizobial endophytes within nodules, suggesting a complex interplay shaped by host selection and compatibility with rhizobial partners. Understanding the structure and dynamics of crop nodule-associated microbial communities is thus critical for optimizing host responses to rhizobia and for leveraging beneficial plant-microbe interactions. This review explores the dualistic nature-both facilitative and inhibitory-of the nodule microbiome in relation to nodulation. We examine the diversity of soil bacteria that stimulate nodulation and those that ultimately colonize nodule tissues, questioning whether these functional groups overlap. Furthermore, we discuss the molecular dialogs and counter-signaling mechanisms that regulate endophyte ingress into nodules, and evaluate how nodule endophytes contribute to plant performance and soil fertility.},

abstract = {Gastric cancer (GC), often diagnosed at advanced or metastatic stages, remains a significant clinical challenge requiring novel biomarkers for early detection, risk stratification, and effective, personalized treatment optimization. Emerging evidence underscores a strong association between gut microbiome dysbiosis and GC initiation, progression, and therapeutic outcomes. This review explores the potential of the advanced/metastatic gastric microbiome as a source of diagnostic and targetable biomarkers and its role in modulating responses to immunotherapy. Although Helicobacter pylori (H. pylori) is the most significant risk factor for GC, several other gastrointestinal taxa-including Fusobacterium nucleatum (F. nucleatum)-have been implicated in advanced GC (AGC). At its inception, microbial dysbiosis contributes to chronic inflammation and immune evasion, thereby influencing tumor behavior and treatment efficacy. Integrating microbiome-based biomarkers into risk stratification, GC staging, and targetable treatment frameworks may enhance early detection, inform immunotherapy strategies, and improve patient-specific treatment responses. Bifidobacterium and Lactobacillus rhamnosus GG have the potential to change the immunotherapy framework with their direct influence on dendritic cell (DC) and cytotoxic T cell (CTL) activity. However, clinical translation is impeded by methodological heterogeneity, causality limitations, and a lack of clinical trials. Nonetheless, the integration of microbiome profiling and the development of therapeutic microbiome modulation strategies, such as personalized probiotics regimens and fecal microbiota transplantation, hold substantial potential for improving clinical outcomes and reducing treatment-related toxicity in GC management.},

abstract = {Plant polyphenols, particularly flavonoids, are prominent bioactives in preventive/complementary therapeutic strategies. This article analyzes how some polyphenols can mitigate oxidative stress and inflammation. These processes are involved in cardiovascular disease, cancer, neurodegeneration, and metabolic disorders. Polyphenols are explored through the integration of direct antioxidant chemistry (radical scavenging via hydrogen atom transfer/single-electron transfer/metal chelation), redox signaling (Keap1-Nrf2/ARE and inflammatory pathways), endogenous antioxidant enzyme systems, and mitochondrial quality control. Unlike previous descriptive reviews, a novel aspect of this manuscript is its evidence-based synthesis, fully supported by structured summary tables that explicitly detail limitations, contradictions, and context dependencies in in vitro, in vivo, and human studies, and identify clinically interpretable endpoints for their application. We describe relevant flavonoids and dietary sources, along with functional outcomes in cardiometabolic-cognitive/neuroprotective-immunometabolic contexts. We integrate representative clinical interventions and nutraceutical applications, highlighting where reported benefits are supported and where the evidence is preliminary. Bioavailability, microbiota-driven biotransformation, and dose realism are considered the primary determinants of in vivo relevance, rather than secondary or descriptive considerations. Future research should prioritize standardized exposure and metabolite profile, dose-appropriate interventions, harmonized clinical endpoints, and stratification strategies that account for microbiome-driven interindividual variability to improve reproducibility and inform nutraceutical and therapeutic use.},

abstract = {Melatonin, an indolic neuromodulator with putative oncostatic and proposed anti-inflammatory properties, primarily demonstrated in preclinical models, is produced at extrapineal sites-most notably in the gut. Its canonical actions are mediated by high-affinity GPCRs (MT1/MT2) and by NQO2, a cytosolic enzyme with a melatonin-binding site (historically termed "MT3"). A growing body of work highlights a bidirectional interaction between the gut microbiota and host melatonin. We integrated two lines of work: (i) three clinical cohorts-cardiac arrhythmias (n = 111; 46-75 y), epilepsy (n = 77; 20-59 y), and stage III-IV solid cancers (25-79 y)-profiled with stool 16S rRNA sequencing, SCFA measurements, and circulating melatonin/urinary 6-sulfatoxymelatonin and (ii) an age-spanning cognitive cohort with melatonin phenotyping, microbiome analyses, and exploratory immune/metabolite readouts, including a novel observation of melatonin binding on bacterial membranes. Across all three disease cohorts, we observed moderate-to-severe dysbiosis, with reduced alpha-diversity and shifted beta-structure. The core dysbiosis implicated tryptophan-active taxa (Bacteroides/Clostridiales proteolysis and indolic conversions) and depletion of SCFA-forward commensals (e.g., Faecalibacterium, Blautia, Akkermansia, and several Lactobacillus/Bifidobacterium spp.). Synthesised literature indicates that typical human gut commensals rarely secrete measurable melatonin in vitro; rather, their metabolites (SCFAs, lactate, and tryptophan derivatives) regulate host enterochromaffin serotonin/melatonin production. In arrhythmia models, dysbiosis, bile-acid remodelling, and autonomic/inflammatory tone align with melatonin-sensitive antiarrhythmic effects. Epilepsy exhibits circadian seizure patterns and tryptophan-metabolite signatures, with modest and heterogeneous responses to add-on melatonin. Cancer cohorts show broader dysbiosis consistent with melatonin's oncostatic actions. In the cognitive cohort, the absence of dysbiosis tracked with preserved learning across ages, and exploratory immunohistochemistry suggested melatonin-binding sites on bacterial membranes in ~15-17% of samples. A unifying microbiota-tryptophan-melatonin axis plausibly integrates circadian, electrophysiologic, and immune-oncologic phenotypes. Practical levers include fiber-rich diets (to drive SCFAs), light hygiene, and time-aware therapy, with indication-specific use of melatonin. Our conclusions regarding microbiota-melatonin crosstalk rely primarily on local paracrine effects within the gut mucosa (where melatonin concentrations are 10-400× plasma levels), whereas systemic chronotherapy conclusions depend on circulating melatonin amplitude and phase. This original research article presents primary data from four prospectively enrolled clinical cohorts (total n = 577).},

abstract = {FABP4 (fatty acid-binding protein 4) is a lipid chaperone and secreted adipokine linking dysregulated fatty acid handling with inflammation, cellular stress, and insulin resistance in obesity. By modulating nuclear receptor signaling (notably PPARγ) and enhancing NF-κB/MAPK activation in adipocytes and macrophages, FABP4 contributes to maladaptive adipose remodeling and systemic metabolic decline. This review critically summarizes recent preclinical evidence on natural bioactive compounds that regulate FABP4 expression and associated adipogenic programs in models of adipogenesis and diet-induced obesity. Data from 3T3-L1/OP9 adipocytes, rodent studies, and selected alternative models indicate that many plant-derived extracts and phytochemicals (e.g., polyphenols, saponins, coumarins, terpenoids, and fermented products) down-regulate FABP4 at mRNA and/or protein levels. These effects are frequently accompanied by suppression of PPARγ/C/EBPα/SREBP1c signaling, activation of AMPK-related pathways, reduced lipid accumulation, and improved metabolic outcomes including lower weight gain, reduced adipocyte hypertrophy, improved steatosis, and favorable serum lipid profiles. Natural compounds from non-plant sources (animal- and microbe-derived metabolites) further broaden FABP4-targeting strategies, supporting FABP4 as a cross-class therapeutic node. Key translational barriers include poor extract standardization, incomplete identification of active constituents, limited oral bioavailability, microbiome-dependent variability, and scarce clinical validation. Future work should prioritize well-characterized lead scaffolds, targeted delivery, rational combinations, and standardized, adequately powered clinical trials assessing dose, durability of FABP4 suppression, and cardiometabolic safety.},

This scoping review explores the composition, function, and systemic influence of BPB, focusing on their metabolic product, butyrate, and its implications for gut integrity, immune modulation, and gut-brain axis (GBA) communication. Disruptions to BPB abundance, which is correlated with Western dietary patterns, food additives, and antibiotic exposure, are linked to gut dysbiosis and associated with a wide spectrum of chronic diseases, including inflammatory bowel disease (IBD), obesity, type 2 diabetes, neurodegenerative disorders, and psychiatric conditions. Butyrate supports colonocyte energy metabolism, reinforces epithelial barrier function, regulates goblet cell mucus production, and exerts anti-inflammatory effects via histone deacetylase inhibition and G-protein-coupled receptor signaling. The depletion of BPB and the resultant butyrate deficiency may represent a unifying pathophysiological mechanism underlying these conditions. Therapeutic strategies that restore BPB populations and butyrate levels, such as prebiotics, dietary fiber, and microbiota-targeted interventions, hold promise for mitigating inflammation and enhancing systemic health through microbiome modulation.},

This study investigated the immunomodulatory potential of microbiome-derived tryptophan metabolites as a novel therapeutic strategy for Cutibacterium acnes (C. acnes)-induced inflammation, focusing on the aryl hydrocarbon receptor (AHR) pathway. We evaluated indole-3-lactic acid (ILA), indole-3-acrylic acid (IAA), and indole-3-propionic acid (IPA) in comparison to tapinarof, utilizing C. acnes-stimulated human epidermal keratinocytes and a C. acnes-induced acne mouse model. In vitro, ILA and IPA significantly suppressed C. acnes-driven inflammatory mediators, including Tumor Necrosis Factor-alpha (TNF-α), Interleukin (IL)-1β, and Cyclooxygenase-2 (COX2), whereas IAA demonstrated limited efficacy. In vivo, ILA treatment exhibited superior therapeutic activity, markedly reducing inflammatory cell infiltration, epidermal hyperplasia, and IL-1β expression. Transcriptomic analysis confirmed that ILA attenuates inflammatory signaling (e.g., IL-17 and TNF pathways) while upregulating AHR-responsive genes such as Cytochrome (CYP) 1A1 and CYP1B1. Collectively, these findings establish ILA as a potent postbiotic that mitigates cutaneous inflammation through selective activation of the AHR. Future studies should prioritize the clinical translation of ILA-based topical formulations, with rigorous evaluation of their efficacy and safety in well-designed human trials, to support their development as a non-antibiotic therapeutic alternative for acne management.},

abstract = {Lipopolysaccharides (LPSs) are potent pro-inflammatory neurotoxins abundant in the gut microbiome and originate primarily from Gram-negative bacteria, such as Escherichia coli. LPS levels increase with brain aging and accumulate around neurons in Alzheimer's disease (AD) brains. Microbiome-generated LPS and other endotoxins cross gut barriers, enter systemic circulation, and translocate across the blood-brain barrier into vascularized brain regions. These processes are exacerbated by aging and neurovascular diseases. Although pro-homeostatic systems mitigate LPS effects, these defenses can fail. This study provides the first evidence that acyloxyacyl hydrolase (AOAH; EC 3.1.1.77), a microglia-enriched LPS detoxifying enzyme, shows reduced expression in AD brain tissue. Analysis of AD patient brains revealed reduced AOAH messenger RNA (mRNA) levels, accompanied by elevated expression of microRNA (hsa-miR-450b-5p), an inflammation regulator. Furthermore, luciferase reporter assays demonstrated that miR-450b-5p specifically targets the AOAH 3'-UTR, leading to a dose-dependent suppression of reporter activity. Also, in vitro experiments on human neuronal glial (HNG) cells further confirmed down-regulation of AOAH expression at protein levels by miR-450b-5p. These findings suggest miR-450b-5p-mediated AOAH deficiency drives LPS-associated neurotoxicity and inflammatory neurodegeneration in AD.},

abstract = {Background/Objectives: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a prevalent condition defined by hepatic fat accumulation, inflammation, and metabolic dysregulation. Current evidence demonstrates that gut microbiota and their metabolites are associated with MASLD pathogenesis. Fermented foods, rich in live microbes and bioactive compounds, actively modulate the gut-liver axis and influence disease progression. This narrative review provides a comprehensive summary of current evidence on the impact of fermented foods on gut microbiota, intestinal barrier function, and gut-liver interactions, and demonstrates their potential role in preventing or mitigating MASLD. Methods: A comprehensive literature search of preclinical and clinical studies was conducted. Specifically, the review focused on fermented-food interventions, modulation of gut microbiota, metabolite production, and effects on hepatic metabolism and inflammation. Results: This review found that fermented foods provide probiotics, prebiotics, short-chain fatty acid (SCFAs), and bioactive compounds that enhance microbial diversity, improve intestinal barrier integrity, reduce endotoxemia, and modulate bile acid and lipid metabolism. Evidence from animal and human studies indicates that fermented food consumption can attenuate hepatic steatosis, inflammation, and metabolic dysregulation, with variability depending on individual microbiome composition. Conclusions: Altogether, these findings suggest that fermented foods represent a promising adjunctive dietary strategy for MASLD by modulating the gut-liver axis and supporting metabolic and hepatic health. Personalized approaches and further long-term clinical trials are required to optimize interventions and establish evidence-based recommendations.},

abstract = {BACKGROUND/OBJECTIVES: Upper respiratory tract infections (URTIs) and exercise-induced immune perturbations are common in adults and may adversely affect quality of life, productivity, and physical performance. Immunoglobulin Y (IgY), a food-derived antibody with broad antimicrobial activity, has demonstrated immunomodulatory potential in preclinical and limited clinical studies. This study evaluated the effects of a multi-pathogen-specific IgY supplement (Muno-IgY) on respiratory health, immune and inflammatory markers, exercise-induced physiological stress, and gut microbiome composition in healthy adults.

METHODS: In this 12-week, double-blind, placebo-controlled trial, 28 healthy adults with a history of URTI were randomly allocated to receive Muno-IgY or placebo and URTI incidence, duration, and severity were recorded daily. Serum immune and inflammatory biomarkers were assessed longitudinally and in response to a standardized exercise challenge. Gut microbiome composition was analyzed using shotgun metagenomic sequencing at baseline and week 12. Safety and tolerability were assessed throughout the study.

RESULTS: URTI incidence was lower in the Muno-IgY group compared with placebo (14.3% vs. 35.7%), with shorter average duration and fewer missed workdays, though differences were not statistically significant (p > 0.05). Following an acute exercise challenge, Muno-IgY supplementation resulted in a significant increase in serum IgA at 24 h post-exercise (p = 0.022) and a significantly greater reduction in lactate dehydrogenase at 1 h post-exercise compared with placebo (p < 0.0001). Exploratory gut microbiome analyses suggested favorable directional shifts, though these changes were not statistically tested.

CONCLUSIONS: In this exploratory pilot study, Muno-IgY supplementation was safe and associated with significant improvements in selected markers of exercise-induced immune response and muscle damage. Numerical trends in URTI incidence and gut microbiome composition were observed but were not statistically significant. These findings are hypothesis-generating and support further evaluation of Muno-IgY in larger, adequately powered clinical trials.},

abstract = {Background/Objectives: After fermentation, yogurt is often supplemented with probiotics, yet sweetened with added sugars that can negatively impact cardiometabolic health. Honey provides rare sugars, oligosaccharides and phenolics that may promote gut and cardiometabolic health. We aimed to determine the impact of yogurt sweetened with commercial clover blossom honey on pro-inflammatory Th17 cytokines and microbial-derived metabolites in healthy postmenopausal women. Methods: In a randomized controlled crossover dietary intervention trial, postmenopausal women (45-65 years of age) consumed two 150 g servings of yogurt for breakfast for 4 weeks, with each serving sweetened with a tablespoon of clover blossom honey or an isocaloric amount of sugar. Blood samples were collected for the measurement of plasma lipids, bile acids (BA) and Th17 cytokines, along with fecal short-chain fatty acids (SCFA). The primary outcome was plasma interleukin (IL)-23. Results: Neither dietary intervention significantly changed IL-23, plasma lipids, fecal SCFA or plasma BA. Compared to sugar-sweetened yogurt, IL-33 was significantly lower after 4 weeks of honey-sweetened yogurt intake. Conclusions: In a healthy population of postmenopausal women, the daily intake for 4 weeks of honey-sweetened yogurt did not significantly impact our primary outcome of IL-23. Instead, lower plasma levels of IL-33 were observed with honey compared to sugar-sweetened yogurt intake. The impact of the intervention on this cytokine was independent of changes in fecal SCFA and plasma BA. Confirmatory studies, in a larger population with levels of honey intake within dietary recommendations for added sugar, are warranted.},

abstract = {Background: Exercise-induced fatigue (EIF) impairs performance and recovery and may contribute to overreaching/overtraining and adverse health outcomes. Beyond classical explanations (substrate depletion, metabolite accumulation, oxidative stress), accumulating evidence indicates that the gut microbiota modulates fatigue-related physiology through metabolic, immune, barrier, and neurobehavioral pathways. Methods: We conducted a structured narrative review of PubMed and Web of Science covering 1 January 2015 to 30 November 2025 using predefined keywords related to EIF, gut microbiota, recovery, and nutritional interventions. Human studies, animal experiments, and mechanistic preclinical work (in vivo/in vitro) were included when they linked exercise load, microbial features (taxa/functions/metabolites), and fatigue-relevant outcomes. Results: Across models, high-intensity or prolonged exercise is consistently associated with disrupted gut homeostasis, including altered community structure, reduced abundance of beneficial taxa, increased intestinal permeability, and shifts in microbial metabolites (e.g., short-chain fatty acids). Evidence converges on four interconnected microbiota-mediated pathways relevant to EIF: (1) energy availability and metabolic by-product clearance; (2) redox balance and inflammation; (3) intestinal barrier integrity and endotoxemia risk; and (4) central fatigue and exercise motivation via microbiota-gut-brain signaling. Nutritional strategies-particularly targeted probiotics, prebiotics/plant polysaccharides, and selected bioactive compounds-show potential to improve fatigue biomarkers and endurance-related outcomes, although effects appear context-dependent (exercise modality, baseline fitness, diet, and baseline microbiota). Conclusions: Current evidence supports a mechanistic role of the gut microbiota in EIF and highlights microbiota-targeted nutrition as a promising adjunct for recovery optimization. Future work should prioritize causal validation (e.g., fecal microbiota transplantation and metabolite supplementation), athlete-focused randomized trials with standardized fatigue endpoints, and precision approaches that stratify individuals by baseline microbiome features and training load.},

abstract = {BACKGROUND/OBJECTIVES: The prevalence of the commensal gut bacterium species, Phascolarctobacterium faecium, has been associated with normal weight in humans. Preclinical evidence suggests that the strain P. faecium DSM 32890 exerts beneficial effects on metabolic and immune function in diet-induced obesity. Herein, we aimed to evaluate the safety and tolerability of this strain in a preclinical study and a pilot interventional trial in humans.

METHODS: A repeated-dose oral toxicity study of 28 days was performed in Wistar rats (male and female), during which adverse signs and clinical outcomes were assessed, along with histological, hematologic, biochemical, and immune markers. Subsequently, a pilot human intervention trial was conducted, including 20 participants (11 overweight and 9 normal weight) who received P. faecium DSM 32890 daily for 15 days. Body composition, dietary intake, physical activity, clinical data, perceived health, gastrointestinal symptoms, and blood analyses were assessed to determine tolerability and identify potential adverse effects.

RESULTS: In rats, the administration of the bacterium did not cause behavioral, physiological, histologic, immune, or biochemical alterations. In humans, there was no evidence of adverse effects on general health, hematological and biochemical profiles, bowel habits, or gastrointestinal symptoms. Overweight participants experienced reductions in flatulence and nausea after the intervention.

CONCLUSIONS: The consumption of P. faecium DSM 32890 did not raise safety concerns and was well tolerated in rats and humans. The findings represent a step forward in the path toward future, longer-term studies to explore the potential efficacy.},

abstract = {Background/Objectives: Nutrition and the gut microbiota influence treatment tolerance and recovery in patients with colon cancer receiving chemotherapy. This pilot study examined changes in diet quality and fecal microbiota over 6 months of chemotherapy and evaluated longitudinal associations between diet quality and gut microbiota diversity and taxa. Methods: 48 adults with stage II-III colon cancer receiving 5-fluorouracil-based chemotherapy were assessed at baseline and 6 months post-initiation. Diet quality was measured using 3-day dietary recalls to calculate Healthy Eating Index (HEI) scores. Stool samples underwent 16S rRNA sequencing to assess Shannon diversity, Beta and taxonomic composition. Pre-post changes were analyzed using paired tests, and associations between HEI and microbiota measures were evaluated using multivariable linear regression adjusting for demographic and clinical covariates. Results: Diet quality declined during chemotherapy, with reduced intake of fiber, fruits and vegetables, and whole grains. Gut microbial alpha diversity decreased over time. At the phylum level, Actinobacteriota decreased, while Bacteroidota and Proteobacteria increased. At the genus level, only Streptococcus (decreased) and Escherichia (increased) remained significantly altered after multiple testing correction. Higher baseline diet quality and improvements over time were associated with greater microbial diversity and lower Proteobacteria abundance. Diet quality was inversely associated with Streptococcus and Escherichia and positively associated with short-chain fatty acid-producing, fiber-responsive genera (Faecalibacterium, Mediterraneibacter, Ruminococcus_E, Fusicatenibacter). Baseline gut microbiota did not significantly associate with changes in diet quality. Conclusions: Chemotherapy was associated with declines in diet quality, gut microbial alpha diversity, along with shifts in beta diversity and microbial taxa. Higher diet quality appeared protective against microbial disruption, supporting a bidirectional relationship between diet and the gut microbiome during chemotherapy. Nutritional and microbiota-focused approaches warrant further investigation in the context of chemotherapy.},

abstract = {Background/Objectives: This study evaluated whether yoghurt containing Apilactobacillus kunkeei DSM 12361 protects rats against non-alcoholic fatty liver disease (NAFLD). We hypothesized that this fructophilic probiotic, with anti-inflammatory properties, may affect NAFLD progression by improving the gut microbiome, lowering intestinal ethanol production, and modulating inflammatory and metabolic pathways linked to hepatic fat accumulation. Methods: Wister rats were randomized into three groups; rats in the control group (HFrD) were fed a high-fructose (70%) diet while rats in experimental groups were fed the same diet mixed with 10% of yoghurt containing YC-180 starter culture (HFrD-Y) or yoghurt containing YC-180 and Apilactobacillus kunkeei DSM 12361 (HFrD-Y-A). Results: After six weeks of intervention, levels of plasma triglycerides, cholesterol, glucose, liver enzymes (ALT and AST), interleukin (IL)-6, fecal ethanol, Enterobacteriaceae, and hepatic index were significantly increased (p < 0.05) in the HFrD group as compared to rats in both experimental groups. Moreover, plasma levels of liver enzymes, lipid profile, glucose, and IL-6 were significantly lower (p < 0.05) in rats of the HFrD-Y-A group than those in the HFrD-Y group. Furthermore, plasma levels of IL-10 and fecal Lactobacilli and Bifidobacteria were significantly increased (p < 0.05) in the experimental groups when compared to rats in the control group. Conclusions: In sum, the obtained results indicated that yoghurt containing Apilactobacillus kunkeei could decrease the risk of non-alcoholic fatty liver disease (NAFLD) through (a) blocking the inflammation process associated with NAFLD, (b) enhancing the lipid profile, (c) lowering fecal ethanol, and (III) decreasing the levels of fecal Enterobacteriaceae in comparison with levels of fecal Lactobacilli and Bifidobacteria in rats. More research on molecular mechanisms of the potential effects of the Apilactobacillus kunkeei strain against NAFLD is still required.},

abstract = {Background: Children with cow's milk allergy (CMA) present alterations in their gut microbiome, but any potential sex-dependency of these has not been addressed. Further, whether eliminating milk from children's diet has similar effects on the gut microbiomes of boys and girls is also not known. Here, our main objective is to analyze how CMA and development of oral tolerance (DOT) to milk proteins affect the gut microbiota in female and male children. We also perform exploratory analyses to investigate whether milk elimination and/or a family history of allergies underlie sex-associated differences. Methods: We obtained 16S rRNA gene sequences of the intestinal microbiota of 32 children aged 5-12 years with CMA, of which 14 had active CMA and 18 had developed oral tolerance, along with 36 age-matched healthy controls (51.5% male). PERMANOVA and differential abundance analyses were employed to evaluate overall compositional differences and to identify bacteria varying between the groups. Results: The effects of CMA on the gut microbiome are more pronounced in girls, including female-specific decreases in bacteria potentially related to protection from allergy, such as Monoglobus and Anaerostipes. The girls' microbiomes were also found to be more influenced by a family history of allergy, remaining farther from the healthy state upon DOT. In contrast, milk elimination affects more taxa in boys in the control group than in girls in the control group, although it alters global microbiome composition in both. In all, milk elimination and family history fail to explain most microbiome alterations observed in CMA, indicating that the latter are specifically linked to disease development. Conclusions: Gut microbiome alterations associated with CMA are sex-dependent, suggesting that sex-specific strategies, dietary and otherwise, may be more effective at modulating them toward healthier states.},

abstract = {Diet plays a central role in shaping the composition and metabolic activity of the oral microbiota, thereby influencing both oral and systemic health. Disturbances in this delicate host-microbe balance, triggered by dietary factors, smoking, poor oral hygiene, or antibiotic use, can lead to microbial dysbiosis and increase the risk of oral diseases such as periodontitis, as well as chronic systemic disorders including diabetes, cardiovascular disease, Alzheimer's disease, and certain cancers. Among dietary contaminants, exposure to toxic heavy metals such as cadmium (Cd), lead (Pb), mercury (Hg), nickel (Ni), and arsenic (As) represents an underrecognized modifier of the oral microbial ecosystem. Even at low concentrations, these elements can disrupt microbial diversity, promote inflammation, and impair metabolic homeostasis. Saliva has recently emerged as a promising, non-invasive biofluid for monitoring nutritional status and early metabolic alterations induced by diet and environmental exposures. Salivary biomarkers, including metabolites, trace elements, and microbial signatures, offer potential for assessing the combined effects of diet, microbiota, and toxicant exposure. This review synthesizes current evidence on how diet influences the oral microbiota and modulates susceptibility to heavy metal toxicity. It also examines the potential of salivary biomarkers as integrative indicators of nutritional status and metabolic health, highlights methodological challenges limiting their validation, and outlines future research directions for developing saliva-based tools in personalized nutrition and precision health.},

abstract = {Background: Protein-energy wasting (PEW) is a major predictor of morbidity and mortality in patients with chronic kidney disease (CKD), even before the initiation of dialysis. Its multifactorial pathogenesis includes reduced dietary intake, chronic inflammation, metabolic acidosis, hormonal disturbances, and dysbiosis of the gut microbiota. Early recognition and targeted management are crucial for preventing muscle loss, functional decline, and adverse outcomes. Methods: This narrative review summarises and integrates current evidence from the literature on nutritional and metabolic interventions to prevent and treat protein-energy wasting in patients with nondialysis chronic kidney disease. Relevant clinical trials, meta-analyses, and experimental studies published up to date were evaluated, focusing on dietary strategies, metabolic modulation, physical exercise, and gut microbiome-targeted therapies. Results: Adequate energy and protein intake remain the cornerstone of PEW management, based on available clinical and observational evidence. Individualised diets emphasising high-quality and plant-based proteins, oral nutritional supplements, and ketoanalogues can attenuate muscle wasting. Correction of metabolic acidosis and inflammation enhances protein anabolism and nitrogen balance. Physical exercise acts synergistically with dietary interventions to preserve muscle mass and function. Novel approaches-such as modulating the gut-kidney axis with pre-, pro-, and postbiotics or supplementing with short-chain fatty acids-show promise in improving metabolic and inflammatory profiles. Conclusions: The management of PEW in nondialysis CKD requires a personalised approach that integrates nutrition, physical activity, metabolic correction and microbiome modulation. Early, coordinated intervention may help to slow the progression of CKD and improve patient survival and quality of life.},

abstract = {BACKGROUND/OBJECTIVES: Lithium (Li), silicon (Si), and boron (B) are proposed nutritional trace elements with potential roles in metabolic, neurobiological, endocrine, inflammatory, and bone-related processes. This review provides a critical synthesis of data on Li-Si-B, emphasizing (i) physiological and mechanistic pathways, (ii) human clinical relevance, (iii) shared biological domains, and (iv) safety considerations.

METHODS: A narrative review was conducted across PubMed, Scopus, and Web of Science from inception to January 2025. Predefined search strings targeted dietary, environmental, and supplemental exposures of lithium, silicon, or boron in relation to metabolism, endocrine function, neurobiology, inflammation, bone health, and the gut microbiome. Inclusion criteria required peer-reviewed studies in English. Data extraction followed a structured template, and evidence was stratified into human, animal, cellular, and ecological tiers. Methodological limitations were critically appraised.

RESULTS: Li, Si, and B influence overlapping molecular pathways including oxidative stress modulation, mitochondrial stability, inflammatory signaling, endocrine regulation, and epithelial/gut barrier function. Human evidence remains limited: Li is supported primarily by small trials; Si by bone-related observational studies and biomarker-oriented interventions; and B by metabolic, inflammatory, and cognitive studies of modest sample size. Convergence across elements appears in redox control, barrier function, and neuroimmune interactions, but mechanistic synergism remains hypothetical.

CONCLUSIONS: Although Li-Si-B display compelling mechanistic potential, current human data are insufficient to justify dietary recommendations or supplementation. Considerable research gaps-including exposure assessment, dose-response characterization, toxicity thresholds, and controlled human trials-must be addressed before translation into public health policy.},

Current evidence indicates that the gut microbiota is linked to cognitive function in both healthy and diseased states, with numerous studies suggesting a potential causal relationship between the two. Although the majority of these studies associate changes in cognitive function with differences in the composition of the gut microbiota, some findings also indicate an inverse relationship.},

These bioactive components, sourced from seaweed, marine crustaceans, and microorganisms, including polysaccharides, polyphenols, and lipids, demonstrate exceptional biocompatibility and specific recognition capabilities. They serve as an optimal carrier matrix and functional core for developing an efficient, precision-targeted intestinal nutrition delivery system. Research findings demonstrate that optimization via innovative delivery technologies, including nanoencapsulation and polymer microsphere encapsulation, enables marine bioactive substances to navigate various physiological barriers in the gastrointestinal tract effectively. This facilitates targeted, sustained release of nutritional components and enhances bioavailability. Simultaneously, these substances may relieve dysbiosis by modulating the composition of the gut microbiota and the quantity and activity of specific metabolic products, thereby reinforcing intestinal barrier integrity. This narrative review systematically examines the sources and functional attributes of marine bioactive compounds, emphasizing their application strategies in developing targeted delivery systems for the gut and their regulatory effects on gut microbiota. It concludes by delineating future research directions in this field, particularly in optimizing carrier functionalities and clarifying action mechanisms.},

This study provides the first comprehensive NSP profiling of 22 populations across three Tunisian Satureja species (S. nervosa, S. graeca, and endemic S. barceloi), using enzymatic analysis, gas chromatography, and multivariate statistics. Total non-starch polysaccharides reached exceptional levels (21.5 ± 3.0 g/100 g dry weight (DW)), with several populations exhibiting unprecedented soluble fiber proportions exceeding 50%, including population SG4 achieving 79.7%. Monosaccharide analysis revealed uronic acid dominance (42.9-52.5% of total NSP), indicating pectin-rich cell walls with distinct functional properties. Principal component analysis (explaining 61.5-84.9% of variance) demonstrated that populations cluster by fiber chemotype rather than taxonomic classification. Hierarchical and K-means clustering identified three distinct clusters in the soluble and total fiber fractions, with uronic acid-dominated populations (SG4, SB, SG18, SN8) and arabinose-xylose enriched populations (SN13, SN12, SN22, SG21) as extreme chemotypes. Intraspecific variation (coefficient of variation, CV: 14.0-50.0%) substantially exceeded interspecific differences. These findings establish Tunisian Satureja as an exceptional functional fiber source and demonstrate that population-level chemical screening outperforms taxonomic classification for developing nutraceuticals targeting cholesterol reduction, glycemic control, and gut microbiome modulation.},

From the perspective of microbial interactions, this review summarizes key concepts and major interaction types-including mutualism, commensalism, and competition-and describes how bacteria, yeasts, and molds interact via metabolic division of labor to drive substrate conversion, flavor formation, preservation, and biosynthesis of functional compounds. Focusing on four representative ethnic fermented foods-Dong fermented fish, Mongoslian milk curd, Miao sour soup, and Manchurian kombucha-we analyze how microbial interactions contribute to product quality, safety, and sensory attributes. Given current challenges in industrializing traditional fermented foods, such as poor standardization and variable quality, we propose future research directions centered on modern microbiome tools, designed microbial consortia, and process optimization. This work aims to provide a scientific foundation and practical strategies for modernization and quality improvement of traditional fermented foods.},

The formation of these esters depends on the metabolism of their precursors-caproic acid and lactic acid-within the pit mud (PM) microbiome. However, the specific taxa driving the metabolic flux from lactate accumulation to caproate synthesis remain unclear. This study aimed to identify potential functional microbes capable of caproate biosynthesis and lactate utilization by systematically analyzing PM samples from the upper, middle, and lower layers of three different pit ages (0, 20, and 50 years). Results showed that 50-year-old PM exhibited significantly higher caproic acid and ammonium nitrogen levels, but lower lactic acid content, compared to the 0- and 20-year-old counterparts. Notably, Petrimonas, Caproiciproducens, and Sedimentibacter were significantly enriched in the 50-year-old PM. Their relative abundances correlated positively with caproic acid and negatively with lactic acid. Furthermore, PICRUSt2 analysis indicated higher abundances of genes associated with caproate synthesis and lactate utilization in the 50-year-old microenvironment. We propose that Petrimonas, Caproiciproducens, and Sedimentibacter are potential functional candidates for lactate degradation and caproate generation. These findings provide a scientific basis for modulating the microbiome for "increasing ethyl caproate and reducing ethyl lactate", thereby enhancing baijiu quality.},

Recent research indicates that nutrition can change the way urothelial cancer forms by affecting inflammation, oxidative stress, cellular energy, and the epigenome. It can also change the risk of BC and how well treatment works. Simultaneous progress in precision nutrition (PN) and nutriomic profiling-encompassing nutrigenomics, nutrigenetics, nutriepigenetics, metabolomics, and microbiome science-presents novel options to tailor dietary regimens beyond universal guidelines. In this review, we consolidate existing knowledge regarding the nutritional factors influencing BC, outline pertinent principles of PN for BC prevention and survival, and explore how urine proteomics and molecular subtyping facilitate the integration of PN into precision oncology. Our review examines the methodological, bioinformatic, biomarker, and clinical translation challenges that impede the implementation of PN in BC management; these challenges include the need for validated nutritional biomarkers with mechanistic endpoints, interoperable data platforms, and rigorously designed clinical trials. Finally, we emphasize future prospects for PN-guided medical nutrition therapy and dietary models during and after systemic treatment recovery. We propose research priorities that will facilitate the integration of PN-informed individualized dietary plans with medical and surgical approaches in BC treatment, aiming to decrease the costs associated with expensive or excessively aggressive treatment methods, thereby supporting long-term survival care. This review seeks to establish a conceptual framework for the integration of PN into BC management by delineating the opportunities and challenges, hence promoting hypothesis-driven research in a promising yet underexplored domain.},

abstract = {Background: Glaucoma is a neurodegenerative disease and the second leading cause of irreversible blindness in developed countries. It is characterized by progressive loss of retinal ganglion cells (RGCs) and optic nerve axons, leading to permanent vision impairment. Although elevated intraocular pressure (IOP) is the main recognized risk factor, recent evidence suggests that ocular and gut microbiota may play a significant role in the onset and progression of glaucoma. Objectives: This study aimed to characterize ocular and gut microbiota alterations in patients with different types of glaucoma. Methods: Five searches were conducted between June and September 2025 using selected keywords. A total of 121 articles were identified, of which 14 met the inclusion criteria following the PRISMA 2020 guidelines. Results: Findings indicate a Mendelian genetic predisposition influencing microbiota composition associated with glaucoma development. Patients treated with benzalkonium chloride (BAK) showed increased Gram-negative and Alphaproteobacteria on the ocular surface, along with enhanced lipopolysaccharide synthesis. Compared with controls, glaucoma patients exhibited reduced Corynebacterium mastiditis and Actinobacteria and increased Firmicutes, Proteobacteria, and Verrucomicrobiota. Dysbiosis was more pronounced in patients with concurrent dry eye disease, characterized by higher Gram-negative taxa and pro-inflammatory microbial activity. Conclusions: Significant differences in ocular and gut microbiota were observed between glaucoma patients and controls, as well as among glaucoma subtypes such as pseudoexfoliation and primary open-angle glaucoma. Age-related dysbiosis and epigenetic factors appear to contribute to disease development. Microbiota profiling may offer new opportunities for improved prediction, management, and treatment of glaucoma.},

abstract = {Background: Many probiotic strains have been studied in relation to irritable bowel syndrome (IBS). The aim of this study was to identify probiotic strains demonstrating efficacy in the management of IBS based on meta-analyses of randomized placebo-controlled trials (RPCTs). Methods: This systematic review was registered in the PROSPERO database (CRD420251047092). Searches were conducted in PubMed and Scopus on 8 April 2025. Additional completed studies with available results were identified through ClinicalTrials.gov. An additional search of the Cochrane Central Register of Controlled Trials (CENTRAL), including records indexed in EMBASE, was conducted in December 2025 and did not identify any additional studies. RPCTs were included if they evaluated single-strain probiotics without additional active components compared with a placebo in patients with IBS. Studies whose results could not be meta-analyzed were excluded. Results: A total of 2643 records were identified; 32 articles evaluating 10 probiotic strains were included in the meta-analyses. Meta-analyses demonstrated the efficacy of Bifidobacterium longum (formerly Bifidobacterium infantis) 35624, Lactobacillus rhamnosus GG, Lactiplantibacillus plantarum 299v (DSM 9843), Saccharomyces cerevisiae CNCM I-3856, and Bacillus coagulans Unique IS2 (MTCC 5260) in improving key IBS symptoms. Meta-analyses also demonstrated that Bacillus coagulans MTCC 5856 improved quality of life for those with IBS. Conflicting results were observed for Saccharomyces boulardii CNCM I-745. Meta-analyses did not demonstrate the efficacy of Escherichia coli Nissle 1917, Lactobacillus gasseri BNR17, or Lactobacillus casei Shirota. Conclusions: Several probiotic strains demonstrated efficacy in the treatment of IBS in meta-analyses of RPCTs.},

abstract = {Background/Objectives: Periodontitis is a chronic inflammatory disease with marked inter-individual heterogeneity and well-established links to cardiometabolic and other systemic conditions. Conventional clinical diagnostics remain indispensable. However, they provide limited real-time insight into molecular activity and host-response biology. This review aimed to synthesize recent advances in point-of-care diagnostics and emerging molecular biomarkers relevant to periodontal disease and its systemic associations. Methods: We performed a state-of-the-art narrative review of literature published between 2018 and 2026. The focus was on point-of-care biosensing technologies and molecular biomarkers assessed in oral and related biological matrices. These included saliva, gingival crevicular fluid, blood, and dental plaque. Evidence was prioritized based on analytical performance, clinical validity, and translational readiness. Results: Substantial progress has been made in multiplex optical and electrochemical point-of-care platforms. These include microfluidic systems and early intraoral wearable sensors. Such technologies enable quantification of host-response proteins, including MMP-8, cytokines, and chemokines. In parallel, omics-derived biomarkers are emerging as clinically informative adjuncts for diagnosis and monitoring. MicroRNAs, cell-free DNA, extracellular vesicle-derived signals, proteomic profiles, and microbiome classifiers demonstrate promising discrimination. They also provide mechanistic links to systemic inflammation. Clinical translation remains limited by study heterogeneity, spectrum bias, and insufficient external validation. Conclusions: Near-term clinical value lies in adjunctive risk stratification and longitudinal disease monitoring. Replacement of conventional periodontal examination is not currently justified. Meaningful clinical and public-health impact will require standardized disease definitions. Harmonized sampling and reporting protocols are essential. Multicenter validation across comorbidity strata is needed. Regulatory-grade evidence must be generated for in vitro diagnostics and artificial intelligence software classified as medical devices.},

abstract = {Background/Objectives: Maternal rectovaginal carriage of Group B Streptococcus (GBS, Streptococcus agalactiae) is a major risk factor for vertical transmission and early-onset neonatal infection. Intrapartum antibiotic prophylaxis reduces early-onset disease but does not address antenatal carriage and may affect the maternal-neonatal microbiota. Microbiota-directed interventions, including probiotics, are being explored as complementary strategies. Methods: This prospective, single-centre, open-label pilot intervention study included 10 pregnant women (18-40 years) with singleton pregnancies and a positive vaginal and/or rectal GBS swab, without pre-gestational or gestational diabetes and without antibiotic use in the 4 weeks before enrolment. Participants received OMNi-BiOTiC[®] FLORA plus (multi-strain lactic acid bacteria, including Lactobacillus crispatus) orally at 2 × 2 g/day from the 15th to the 34th gestational week. Microbiological swabs were obtained at qualification (12-15 weeks), mid-pregnancy (22-25 weeks), and late pregnancy (34-35 weeks). Outcomes were described descriptively. Results: Among 56 screened pregnant women, 10 were GBS-positive (17.9%) and enrolled. All participants were GBS-positive at baseline. At 22-25 weeks, 5/10 (50%) had a negative GBS result. At 34-35 weeks, 9/10 (90%) were GBS-negative, while 1/10 (10%) remained colonised. Time to first negative result ranged from 7.6 to 20.2 weeks from supplementation start (median 8.6 weeks). No recurrences (negative-to-positive transitions) were observed between the second and third sampling points. No adverse events related to supplementation were reported. In contrast, among the 46 women who were GBS-negative at screening and did not receive probiotic supplementation, 14 (30.4%) were found to be GBS-positive at routine screening performed at 35-37 weeks of gestation. Conclusions: In this pilot single-arm study, oral supplementation with a multi-strain probiotic preparation during pregnancy was associated with a time-dependent reduction in rectovaginal GBS carriage and was well tolerated. These preliminary findings support the feasibility of larger randomised controlled trials incorporating microbiome profiling and neonatal outcomes.},

abstract = {Primary hyperoxalurias (PHs) are rare autosomal recessive disorders characterized by overproduction of oxalate, a metabolic end product that readily forms calcium oxalate crystals. Excess hepatic oxalate leads to recurrent kidney stones, nephrocalcinosis, and progressive renal injury, often culminating in end-stage kidney disease (ESKD). Once renal clearance declines, systemic oxalate accumulation can cause multisystem deposition. PH encompasses three types-PH1, PH2, and PH3-caused by deficiencies in the hepatic enzymes AGT, GRHPR, and HOGA1, respectively, resulting in accumulation of glyoxylate and subsequent oxalate overproduction. Clinical presentation varies from infantile oxalosis to adult-onset recurrent nephrolithiasis, with PH1 generally being the most severe. Diagnosis relies on urinary oxalate measurements, plasma oxalate in advanced chronic kidney disease, urinary metabolite profiling, imaging, and genetic testing. Management includes hyperhydration, citrate supplementation, pyridoxine for responsive PH1 patients, dialysis and transplantation when required, while RNA interference therapies targeting glycolate oxidase or LDHA have demonstrated substantial biochemical efficacy in PH1 and represent promising emerging therapeutic options, although long-term clinical outcome data remain limited and broader applicability to other PH types is still under investigation. Future strategies focus on modulating intestinal oxalate absorption, gut microbiome therapies, oxalate-degrading enzymes, and novel gene-editing approaches. Early diagnosis and individualized management are critical to prevent kidney injury and systemic oxalosis. In this review, we summarize the genetic, biochemical, and clinical features of PH and discuss current and emerging therapeutic strategies.},

abstract = {Introduction: Parkinson's disease can influence oral health by impairing motor function and altering salivary composition, potentially affecting the oral microbiome. Materials and Methods: The objectives of this study are fourfold: (a) to compare the prevalence of bacterial species associated with periodontal disease in patients with and without Parkinson's disease (PD), (b) to assess whether the coexistence of periodontal disease in PD patients contributes to an imbalance in the oral microbiome, (c) to evaluate the correlation between periodontal clinical indices (plaque index, tartar index, bleeding index, and probing depth) and the concentrations of specific periodontopathogenic bacterial species, and (d) to explore the potential implications of these evidences for clinical management and preventive strategies in Parkinson's patients. The main objective of this study is to compare periodontal clinical indices (plaque index, tartar index, bleeding index, and probing depth) and the bacterial profile of patients with periodontal and Parknson's disease. Two groups were included: 15 patients with periodontal disease (control group) and 16 patients with both periodontal and Parkinson's disease (study group). Microbial samples were collected from the periodontal pockets at baseline and analyzed using the Polymerase Chain Reaction (PCR) Perio-Ident 12 kit to detect major periodontal pathogens. Results: Periodontal indices showed no statistically significant differences between groups, although the study group presented lower mean tartar index (49.31% vs. 67.4%, p = 0.069), bleeding on probing (44.31% vs. 56.67%, p = 0.137), and plaque index (66% vs. 68.93%, p = 0.754). Median bacterial loads were generally higher in control group, with Tannerella forsythia, but without statistically significant difference (p = 0.072). Significant correlations between plaque index and multiple pathogens occurred only in control gorup, suggesting disrupted plaque-pathogen dynamics (p < 0.05). Conclusions: The results highlight the potential value of integrating clinical and microbiological assessment when managing periodontal disease in patients with Parkinson's disease.},

abstract = {Colorectal cancer (CRC) cachexia is a multifactorial, treatment-limiting syndrome characterized by progressive loss of skeletal muscle with or without loss of fat mass, accompanied by systemic inflammation, anorexia, metabolic dysregulation, and impaired treatment tolerance. Despite decades of work, cachexia remains clinically underdiagnosed and therapeutically underserved, in part because canonical models treat tumor-derived factors and host inflammatory mediators as a largely 'host-only' network. In parallel, CRC is strongly linked to intestinal dysbiosis, barrier disruption, and microbial translocation. Extracellular vesicles (EVs)-host small EVs, tumor-derived EVs, and bacterial extracellular vesicles (including outer membrane vesicles)-may provide a mechanistically plausible, information-dense route by which these domains could be coupled. Here, we synthesize emerging evidence suggesting that cross-kingdom EV signaling may operate as a vesicular ecosystem spanning gut lumen, mucosa, circulation, and peripheral organs. We propose the "vesicular intersection layer" as a unifying framework for how heterogeneous EV cargos converge on shared host decoding hubs (e.g., pattern-recognition receptors and stress-response pathways) to potentially contribute to muscle catabolism. We critically evaluate what is known-and what remains unproven-about EV biogenesis, trafficking, and causal mechanisms in CRC cachexia, highlight methodological constraints in microbial EV isolation and attribution, and outline minimum evidentiary standards for cross-kingdom claims. Finally, we translate the framework into actionable hypotheses for EV-informed endotyping, biomarker development (including stool EV assays), and therapeutic strategies targeting shared signaling nodes (e.g., TLR4-p38) and endocrine mediators that are predominantly soluble but may be fractionally vesicle-associated (e.g., GDF15). By reframing CRC cachexia as an emergent property of tumor-host-microbiota vesicular communication, this review provides a roadmap for mechanistic studies and clinically tractable interventions.},

abstract = {Genitourinary malignancies are characterized by marked heterogeneity in tumor biology, clinical behavior and therapeutic outcomes. Despite significant progress in surgical and systemic treatments, resistance to therapy remains a major challenge, highlighting the need to identify additional host-related determinants of disease progression and treatment response. Within this framework, converging experimental and clinical evidence indicates that host-associated microbial ecosystems may influence key biological processes involved in tumor-host interactions, including immune modulation, metabolic regulation and inflammatory pathways. Altered microbial profiles have been associated with oncogenic signaling, changes in the tumor microenvironment and differences in clinical benefit from systemic therapies, particularly immunotherapeutic approaches. This review brings together preclinical, translational and clinical evidence on the involvement of microbiota in renal, prostate, bladder and testicular cancers, with attention to biological mechanisms and clinically meaningful correlations with disease characteristics. While current data are largely observational, early interventional studies suggest that modulation of microbial ecosystems may influence therapeutic activity in selected clinical settings. Collectively, these findings support microbiota as a relevant component of genitourinary cancer biology with potential implications for precision medicine approaches.},

abstract = {Cancer remains a leading cause of morbidity and mortality worldwide, and effective strategies for cancer prevention are urgently needed to complement therapeutic advances. While dietary factors are known to influence cancer risk, the molecular mechanisms that mediate inter-individual responses to nutritional exposures remain poorly defined. Emerging evidence identifies long non-coding RNAs (lncRNAs) as pivotal regulators of gene expression, chromatin organization, metabolic homeostasis, immune signaling, and cellular stress responses, the core processes that drive cancer initiation and progression and are highly sensitive to nutritional status. In parallel, advances in precision nutrition have highlighted how variability in genetics, metabolism, microbiome composition, and epigenetic landscapes shape dietary influences on cancer susceptibility. This review integrates these rapidly evolving fields by positioning lncRNAs as molecular conduits that translate dietary exposures into transcriptional and epigenetic programs governing cancer development, progression, and therapeutic vulnerability. We provide mechanistic evidence demonstrating how dietary bioactive compounds and micronutrients, including polyphenols [such as curcumin, resveratrol, epigallocatechin gallate (EGCG)], flavonoids, alkaloids such as berberine, omega-3 (ω-3) fatty acids, folate, vitamin D, probiotic metabolites (such as butyrate and propionate), and trace elements (such as selenium and zinc), modulate oncogenic and tumor-suppressive lncRNAs. These nutrient-lncRNA interactions influence cancer-relevant pathways controlling proliferation, epithelial-mesenchymal transition (EMT), inflammation, oxidative stress, and metabolic rewiring. We further discuss emerging lncRNA signatures that reflect nutritional and metabolic states, their potential utility as biomarkers for individualized dietary interventions, and their integration into liquid biopsy platforms. Leveraging multi-omics datasets and systems biology, we outline AI-driven frameworks to map nutrient-lncRNA regulatory networks and identify targetable nodes for cancer chemoprevention. Finally, we address translational challenges, including compound bioavailability, inter-individual variability, and limited clinical validation, and propose future directions for incorporating lncRNA profiling into precision nutrition-guided cancer prevention trials. Together, these insights position lncRNAs at the nexus of diet and cancer biology and establish a foundation for mechanistically informed precision nutrition strategies in cancer chemoprevention.},

The gut microbiome has emerged as a potential modulator of chemotherapy efficacy, yet its role in breast cancer remains underexplored. This study aimed to characterize gut microbial composition, functional potential, and microbially derived metabolites in breast cancer patients undergoing NAC. Methods: baseline stool samples from 39 chemotherapy-naïve breast cancer patients undergoing NAC were analyzed using shotgun metagenomic sequencing and targeted metabolomics. Patients were stratified by pathological complete response (pCR, n = 17; no pCR, n = 22). Microbial taxonomic and functional profiles, short-chain fatty acids (SCFAs) and bile acids were assessed, with subgroup analysis performed in triple-negative breast cancer (TNBC). Results: Patients achieving pCR exhibited significantly higher baseline microbial richness compared to non-responders (p = 0.040). Differential abundance analysis revealed enrichment of Dialister, Kineothrix, and Jutongia in responders, whereas Rothia, Leuconostoc, Klebsiella, Jingyaoa, Cuneatibacter, Youxingia, and Bittarella were enriched in non-responders. SCFAs (acetate, propionate and butyrate) positively correlated with microbial glucose catabolic pathways, while caproate was negatively associated with multiple amino acid, lipid, vitamin, and cell wall biosynthesis pathways, including peptidoglycan maturation. Metabolomic analysis identified higher deoxycholic acid (DCA) levels in non-responders and increased C6 levels in responders, although these associations did not remain significant after multiple testing correction. Similar trends were observed in the TNBC subgroup (n = 15). Conclusions: Baseline gut microbiome diversity, taxonomic composition, and functional metabolic potential are associated with response to neoadjuvant chemotherapy in breast cancer, supporting the gut microbiome and its produced metabolites as a potential biomarker of treatment efficacy.},

abstract = {Picea schrenkiana is a keystone species in Central Asian ecosystems currently threatened by climate-driven disease outbreaks. Here, we investigated the causal agent of needle blight and characterized the associated microbial dynamics. By integrating tissue isolation, Koch's postulates, and high-throughput amplicon sequencing across a disease severity level, we confirmed Lirula macrospora as the etiological agent. Community analysis revealed that disease severity is the primary driver of succession, with alpha diversity peaks at the moderate infection stage. Notably, the abundance of Lirula surged from 2.56% in healthy needles to 65.10% in severe cases, displacing the core endophyte Phaeococcomyces, while potentially beneficial bacteria like Sphingomonas showed only transient enrichment. Furthermore, cross-kingdom co-occurrence network analysis revealed marked topological restructuring whereby the system reached a complex ecological "tipping point" during moderate stage before undergoing significant simplification. As the disease progressed, L. macrospora shifted from a peripheral node to a central hub, effectively dismantling the native microbial network. We conclude that L. macrospora infection triggers a cascading collapse of the needle microbiome, driving a phase shift from a healthy homeostasis to a pathogen-dominated state. These findings elucidate the critical mechanisms of pathogen-microbiome interactions and provide a theoretical basis for the ecological management of P. schrenkiana forests.},

abstract = {Maximizing the agricultural output on inherently infertile land and minimizing the environmental cost remain central research imperatives. Albic black soil typifies such infertility. Conventional practice relies on fertilization and straw incorporation, but the albic layer's impermeability funnels applied nutrients into adjacent aquatic systems. Therefore, this study developed deep placement fertilization by lodging fertilizer directly within the albic layer to block hydrologic loss. The feasibility of mechanization was first validated in pot experiments. Soybeans were allocated to six treatments simulating fertilizer placement at different soil depths: control (C), control and fertilizer (CF), surface soil mixing (SM), surface soil mixing and fertilizer (SMF), plow pan soil mixing (PM), and plow pan soil mixing and fertilizer (PMF). The treatments used 20 cm tillage, and the data were collected after 15, 25, and 35 days and at harvest. Integrative transcriptomic, proteomic, metabolomic, and soil microbiome profiling revealed that fertilizer positioned at 25 cm in the albic layer increased yield, restructured the rhizobiont community and promoted arbuscular mycorrhizal fungal colonization. Among the fertilizer treatments, CF had the best growth, and SMF was inhibited by a nutrient shortage. SMF and PMF lost water faster than CF. Abscisic acid (ABA) conveyed the subterranean fertilization signal to the leaf. The enrichment of Vicinamibacterales, Xanthobacteraceae, and Glomeromycota in soil lowered the ABA content in the roots, which upregulated thymidine kinase and peroxidase upon arrival in the leaf, increasing yield. These findings provide a transferable benchmark for any parent material exhibiting poor hydraulic conductivity.},

These pathogens can persist in soil for many years, making them particularly difficult to control. To establish infection, they deploy a diverse arsenal of effector proteins that manipulate host immune responses, disrupt vital cellular functions, and may influence the rhizosphere microbiome to facilitate successful colonization. Phytophthora relies heavily on RxLR effectors to disrupt intracellular immunity, while Pythium species predominantly deploy necrosis-inducing NLPs and cell wall-degrading enzymes, with no confirmed canonical RxLR effectors, suggesting distinct evolutionary strategies. This review aims to explore the detailed mechanisms of plant-pathogen interaction. In recent years, significant progress has been made in understanding the molecular dialogue between pathogens and their hosts, particularly how pathogenic species such as Phytophthora and Pythium manipulate plant immunity through effector secretion, and how plants counteract by activating defense mechanisms at molecular, cellular, and biochemical levels, including changes in hormone signaling, reactive oxygen species (ROS) dynamics, and defense gene expression. The review also outlines emerging disease management strategies and integrative approaches guided by effector biology and microbiome insights.},

This study employed a controlled pot experiment with five widely cultivated Chinese tea cultivars (Camellia sinensis) to investigate how cultivar-specific variation influences rhizosphere microbial communities and their assembly processes. Rhizosphere soil microbiomes (bacterial and fungal communities) and metabolomes were characterized using 16S rRNA and ITS2 amplicon sequencing combined with untargeted metabolomics. Significant differences in rhizosphere metabolite composition, primarily organic acids, fatty acids, and carbohydrates, were observed among cultivars, which corresponded to distinct bacterial and fungal community structures. Redundancy analysis (RDA) revealed that rhizosphere metabolites explained 19.87% of bacterial and 21.63% of fungal community compositional variation, second only to soil physicochemical properties. Neutral community model and modified stochasticity ratio analyses indicated that microbial assembly across cultivars was predominantly deterministic, and rhizosphere metabolite profiles were strongly correlated with microbial community structure. Notably, arbuscular mycorrhizal fungi made up about 11% of the fungal communities in minimally fertilized pot systems, contrasting sharply with their near-absence in conventionally managed systems plantations. These findings demonstrate that tea cultivar genotype significantly shapes rhizosphere microbiome assembly through metabolic differentiation, providing a theoretical foundation for integrating microbiome considerations into tea breeding programs and developing cultivar-specific management strategies.},

abstract = {The study investigated differences in ruminal and fecal microbiota composition, fermentation traits, and volatile organic compounds (VOC) in Simmental dairy cows classified as high (HME) or low (LME) methane emitters. Methane emissions from 48 cows were quantified using the Laser Methane Smart portable gas detector. The 12 animals with the highest and lowest emissions were selected and assigned to the HME and LME groups, respectively, balanced for body weight, days in milk, and body condition score. Rumen fluid and fecal samples were analyzed for pH, ammonia, volatile fatty acids (VFA), VOC, and microbiota composition. As expected, CH4 emissions were significantly higher in HME than in LME cows (22.5 vs. 13.2 g/kg DMI; 16.9 vs. 8.4 g/kg FCM). The neutral detergent fiber digestibility was higher in HME cows (51.4% vs. 47.9%). The valeric acid concentration and the acetate-to-propionate ratio were significantly higher in HME cows (3.53 vs. 3.31). The VOC profiles significantly differed between groups in both feces and rumen fluid. The microbiota analysis revealed a significant difference between groups at the order and genus levels (Bray-Curtis dissimilarity). The Shannon index was higher in LME cows (2.08 vs. 1.95). HME cows exhibited a higher abundance of Methanosphaera and Methanobacteriales. Overall, the results indicate that re-shaping the rumen microbial community can play a key role in reducing methane emissions, strengthening the case for microbiome-driven approaches and offering insights that can support mitigation strategies across dairy production systems.},

abstract = {Fungal bioaerosols play a critical ecological and health role in intensive poultry production systems. However, their dynamic characteristics and community succession patterns in confined cage environments during winter remain poorly understood. This study investigated a typical confined broiler house in Hebei Province, China, during winter. A combined approach of Andersen six-stage sampling, colony counting, and Internal Transcribed Spacer (ITS) high-throughput sequencing was employed to comprehensively analyze the concentration, particle size distribution, diversity, and community composition of fungal bioaerosols across three key growth stages: 7 days (brooding phase), 21 days (growing phase), and 35 days (finishing phase). The results revealed a significant increasing trend in fungal aerosol concentration as the rearing cycle progressed, increasing from 1125 ± 125 CFU/m[3] at day 7 to 3872 ± 565 CFU/m[3] at day 35 (p < 0.001), reaching high-risk exposure levels in the later stages. Small-sized fungal bioaerosols (<4.7 μm) were dominant across all stages (54.35-65.50%), with the highest proportion observed at day 21, indicating their potential for deep respiratory deposition and long-distance airborne transmission. The number of Operational Taxonomic Units (OTUs), along with Chao1 and Shannon indices, increased significantly with bird age (p < 0.001), demonstrating a clear community succession from early-stage yeast-dominated forms (e.g., Diutina, Blumeria) to mid- and late-stage assemblages dominated by filamentous fungi (e.g., Aspergillus, Cladosporium, Alternaria). Notably, several zoonotic pathogenic genera were detected throughout all rearing stages, highlighting the potential risks of airborne fungi to animal health, occupational exposure, and environmental safety under winter ventilation restrictions. This study characterizes a stage-dependent pattern of increasing airborne fungal concentrations accompanied by shifts in particle size distribution and community composition under winter confined conditions. The findings provide a crucial scientific basis for optimizing winter ventilation and environmental management strategies, improving environmental control technologies, establishing airborne biosafety standards, and developing targeted fungal monitoring and prevention technologies.},

These feed supplements were subjected to a 60-day experimental period, during which 120 fish (26.4 ± 5.2 g) were distributed into four groups, with each group comprising 30 fish. The feed supplements were administered at a rate of 1 g/kg of body weight. Before the trial, the fish were acclimatized for two weeks, then injected with Passive Integrated Transponder (PIT) tags. The results showed that none of the feed supplements exhibited a significant effect (p > 0.05) on growth indices. In contrast, the villi length, villi width, muscular thickness, and crypt depth in the anterior, mid, and posterior intestine of the SC group exhibited significant (p < 0.05) improvements compared to the other groups. No alteration or abnormal growth were noticed in the gills and livers. The most dominant microbe genera in all groups, with abundances greater than 60% of the total, were Cetobacterium and Aeromonas. However, Polynucleobacter, Nordella, Mycoplasma, Romboutsia, and Staphylococcus species were present at lower abundances. The presence of Actinobacteria has been observed only in the intestine of fish that have been fed a diet supplemented with PA. It can be concluded that the tested probiotics and the yeast cell wall prebiotic have the potential to produce a remarkable improvement in intestinal morphology and a considerable change in the gut microbiome without notable effect on growth, livers, or gills of common carp.},

This review integrates evidence from the anatomy and physiology of the canine olfactory organ, neurobiological mechanisms of odor transduction and coding, and links between olfaction, memory, and emotion, alongside molecular genetics, evolution, domestication, and selective breeding. We synthesize findings indicating that complex nasal turbinates and specialized airflow patterns enhance odorant capture, while olfactory bulb circuitry and downstream connections to limbic and frontal networks support discrimination, learning, and affective modulation. Comparative and breed-focused studies suggest that skull morphology and breeding priorities can alter olfactory capacity, with shortened nasal anatomy associated with reduced functional potential in some lines. In applied contexts, detection success is strongly shaped by behavioral traits such as motivation, persistence, independence, and reward value, as well as by physical condition and environmental stressors that can impair search efficiency. Emerging literature further suggests that the gastrointestinal and upper airway microbiome, together with diet, housing, temperature, and workload, may influence sensory and cognitive readiness, although direct causal links to detection outcomes remain limited. Overall, canine olfactory performance reflects interactions among genetic-anatomical capacity, neurobehavioral factors, and environment, underscoring the value of standardized selection, training, welfare management, and future integrative research.},

GS from three red cultivars (L-GS, CS-GS, M-GS) were dried, milled, and assessed for safety; their average total polyphenol content was approximately 15 g/kg DM. 3 Holstein cows underwent a 7-week trial consisting of alternating control (CTRL) and GS-supplemented periods (2% DM). Weekly milk samples (n = 21) and corresponding mini-cheeses (n = 21) were analyzed. GS supplementation did not affect milk coliforms (2.3-2.5 log CFU/mL), while total mesophilic counts were significantly lower in M-GS (2.8 ± 0.46 log CFU/mL) than in CTRL (4.5 ± 0.71; p < 0.05). Acinetobacter dominated the milk microbiota but decreased from 34.0% in CTRL to 18.0% in L-GS. Cheese total polyphenols were highest in CS-GS (224 ± 34 mg/kg). [1]H-NMR and VOCs profiling indicated cultivar-dependent shifts in carbohydrate-related metabolites and short-chain fatty acids. Overall, GS supplementation subtly modulated cheese biochemical and aromatic traits without impairing technological performance, supporting the valorization of winery by-products within integrated dairy-viticulture systems.},

While traditional research has primarily focused on genetics, endocrinology, and immune regulation, emerging microbiome studies reveal that commensal microbiota within the gut and reproductive tracts play an underestimated yet pivotal role in host reproductive health. This review systematically synthesizes recent advances regarding the relationship between the microbiome and reproductive functions in major livestock species (cattle, pigs, sheep, and chickens). We first delineate the theoretical basis and mechanisms of the "gut-reproductive axis," highlighting cross-system communication mediated by microbial metabolites, including short-chain fatty acids (SCFAs), indoles, and bile acids. Subsequently, we provide an in-depth comparative analysis of the microecological features of both female (vagina/uterus) and male (semen/epididymis) reproductive systems, examining their impacts on fertility, sperm quality, and pregnancy outcomes. Furthermore, we explore the molecular and systemic mechanisms governing microbial regulation of reproduction, encompassing the modulation of the hypothalamic-pituitary-gonadal (HPG) axis, the balance of local mucosal immunity and inflammation, and epigenetic regulation. Finally, we address current challenges-such as causal validation and the scarcity of multi-species databases-and propose future directions, including spatial multi-omics, AI-integrated analysis, and microbial intervention strategies. Ultimately, this review aims to offer a theoretical foundation and translational insights for elucidating reproductive regulatory networks and developing microbiome-driven precision strategies to enhance reproductive performance.},

abstract = {In fish gut microbiome studies, there are no standardized protocols regarding sampling region or post-feeding time, nor clear consensus on whether analyses should target resident (autochthonous) or transient (allochthonous) bacteria. This study examined the dynamics and interactions of both microbial communities in the anterior and posterior intestine of farmed gilthead sea bream and evaluated the resident microbiome at 24 and 48 h post-feeding. Microbial DNA was sequenced using the Oxford Nanopore Technology platform. Data were analyzed through statistical and discriminant approaches, as well as a Bayesian network framework to assess bacterial interactions. Transient communities showed higher richness and diversity, regardless of intestinal section, suggesting a more specialized and stable microbial environment in the mucus layer. The two communities differed markedly in structure and composition. Variations associated with intestinal region were less pronounced, particularly for autochthonous bacteria, and post-feeding fluctuations in the resident microbiome were minimal. Functionally, results indicated relevant synergies between communities. Protein metabolism pathways were enriched in autochthonous bacteria, whereas allochthonous microorganisms contributed mainly to bile acid and carbohydrate metabolism. Overall, resident and transient bacteria constitute distinct communities in the gut of gilthead sea bream, with numerous genera present in both but most being differentially represented and interconnected.},

abstract = {Microbial communities profoundly influence host aging, yet how natural genetic variation determines microbiota-driven longevity remains unclear. By screening root-derived bacterial isolates across genetically diverse Caenorhabditis elegans strains, we identified striking phenotypic heterogeneity, ranging from lifespan extension to accelerated aging. Combining classical genetic analysis, quantitative trait locus (QTL) mapping and CRISPR-Cas9 allelic recapitulation, we identify skn-1 (Nrf2) and gsy-1 (glycogen synthase) as key host determinants. We demonstrate that strains with mutations or specific natural variants in these loci exhibit a compromised redox buffering capacity, leading to systemic oxidative stress, loss of tissue integrity, and premature death upon microbial challenge. Conversely, robust hosts utilize the same microbial signals to promote longevity. Notably, lifespan defects in susceptible individuals were rescued by antioxidant supplementation. These findings establish redox homeostasis as a central axis in host-microbe-aging interactions and provide a mechanistic framework for precision microbiome interventions tailored to host genetic backgrounds.},

abstract = {OBJECTIVE: To characterize and compare the fungal urinary microbiome ("mycobiome") in healthy women and those with overactive bladder (OAB), and secondarily compare the mycobiome by comorbidities, recent antibiotic exposure, and response to OAB therapy.

MATERIAL AND METHODS: DNA was isolated from urine of those with and without OAB and underwent internal transcribed spacer (ITS) sequencing to detect fungi. Alpha- and beta-diversity, and relative abundance of fungal taxa were analyzed and compared by patient characteristics including OAB status. Fungal-bacterial interactions were identified.

RESULTS: A total of 152 participants were included and fungi were detected in 98% of samples. The most abundant fungal phyla were Basidiomycota and Ascomycota. The most abundant genera were Malassezia, Candida, and Aspergillus. Candida was more abundant in the urine of individuals without OAB (p = 0.01) and Debaryomyces was more abundant in individuals with OAB (p = 0.02). Beta diversity differed between individuals with and without OAB and by diabetes mellitus status (p < 0.05). Relative abundance of fungal genera differed by OAB phenotype, diabetes mellitus status, antibiotic use, and response to OAB treatment (p < 0.05). Fungal-bacterial interaction networks demonstrated a central role of fungi in the interkingdom community structure.

CONCLUSIONS: The study provides new insights into the fungal composition of urine in the physiological state as well as in the context of OAB. Fungi appear to play a central role in interkingdom fungal-bacterial interaction networks. The findings pave the way for future investigations to assess the role of urinary fungi in urologic health and disease, and its modulation to augment therapy.},

abstract = {UNLABELLED: Concentrated supplementary feeding is an effective strategy for addressing nutritional deficiencies in yaks during the cold-season grazing period. However, limited research has investigated whether long-term implementation may alter the gut microbiota and metabolite profiles of yaks, potentially posing health risks to the host. This study investigated the regulatory role of Lactobacillus fermentum in host metabolism through the gut microbiota, employing a “nutrition-gut-metabolism” perspective. Eighty healthy male Pamir yaks with similar body conditions were randomly divided into four groups (n = 20 per group), including Control (Con), Medium Energy (ME), High Energy (HE), and Medium Energy plus Lactobacillus fermentum (MEJ). Body weight was recorded every 30 days during the 150-day trial. Jejunal tissues and contents from nine yaks per group were collected for subsequent analyses. Key findings revealed that the HE group showed significantly increased crypt depth and elevated relative abundance of Clostridium_sensu_stricto_1 (P < 0.05). In contrast, the MEJ group reversed the decline in villus height and width observed in the ME group, while significantly enhancing muscularis thickness. Notably, MEJ yaks exhibited higher abundance of Paeniclostridium, Romboutsia and Treponema (P < 0.05) and markedly increased short-chain fatty acids concentrations (P < 0.001). Metabolomic analysis identified upregulated pathways, including D-amino acid metabolism and Neuroactive ligand-receptor interaction. Furthermore, comparative analyses pinpointed five critical microbial taxa (e.g., vadinBE97, Lachnospiraceae_UCG-008) and 18 key metabolites (e.g., 15-Deoxyprostaglandin J2, Lasalocid A) associated with these effects. In conclusion, Lactobacillus fermentum supplementation improved yak growth performance and mitigates metabolic risks linked to excessive energy intake. These findings provided a theoretical foundation for optimizing yak feeding strategies and advancing precision nutrition in ruminant production.

abstract = {BACKGROUND: Long-term abuse of methamphetamine (MA) is strongly associated with severe lung injury. Microbiome metabolites are one way to understand the interactions between microbes and disease. Although gut microbes and their metabolites play a crucial role in the gut-lung axis, the microbial mechanism by which MA induces lung injury is unclear. The purpose of this work was to identify the omics characteristic factor associated with MA abuse and explore its immune regulatory mechanism by 16 s rDNA sequencing, LC-MS/MS non-targeted metabolomics analysis, hemodynamics, flow cytometry, and some methods of cellular and molecular biology and morphology.

RESULTS: Based on the joint analysis of the gut microbiome and metabolomics, it was found that MA abuse disrupted the structure of the gut microbiome and drove the reprogramming of metabolites, leading to a reduction in Lactobacillus rhamnosus and its metabolite L-kynurenine (L-KYN). Activated Lactobacillus increased L-KYN level in MA-administrated mice. L-KYN, as a product of Lactobacillus, is a key omics signature factor for MA abuse, which has been further confirmed in vivo. L-KYN induced Treg cells differentiated from CD4[+] T cells and reshaped the immune microenvironment. L-KYN induced the secretion of IL-10 by Treg cells, mediated the communication between Treg cells and alveolar epithelial cells (AEC) through IL-10, and alleviated MA-induced lung inflammation and alveolar barrier damage through the IL-10/JAK1/STAT3 pathway.

CONCLUSIONS: From the perspective of intestinal microbiome-metabolite-immune network regulation, the omics characteristic factor L-KYN reshaped the immune microenvironment and alleviated methamphetamine-induced chronic lung injury through the gut-lung axis, providing a new theoretical and experimental basis for the prevention and treatment of MA-induced chronic lung injury.

abstract = {We read the recent systematic review and meta-analysis on nutrition-based, gut microbiota-targeted interventions for sarcopenia in older adults with great interest. While the evidence suggests that probiotics and fiber-enriched diets may improve surrogate outcomes such as muscle strength and gait speed, we highlight two priorities to strengthen future mechanistic and clinical translation. First, microbiome measurements in existing trials are often limited to genus-level taxonomic shifts, which can be biologically misleading because a single genus may include members with divergent immunomodulatory properties. Even species-level profiling may be insufficient, as strains within the same species can differ markedly in genetic content and metabolic capacity. Moreover, taxonomic composition does not necessarily reflect functional output due to functional redundancy across microbial communities. We therefore recommend transitioning to whole-genome shotgun metagenomics to enable strain-level resolution and functional profiling, allowing investigators to quantify pathways and metabolites relevant to muscle preservation, including short-chain fatty acids and vitamin biosynthesis. Second, we argue that improvements in sarcopenia-defining parameters should be linked to patient-centered clinical benefit. Future randomized controlled trials should be adequately powered to assess hard endpoints, including falls, fractures, hospitalization rates, and functional independence, alongside muscle mass and performance measures, to establish whether microbiota modulation delivers meaningful reductions in healthcare burden.},

abstract = {INTRODUCTION: Mild-to-moderate scalp seborrheic dermatitis (SD) is commonly managed by using anti-SD shampoos containing antifungal, anti-inflammatory, and keratolytic agents. A newly formulated anti-SD shampoo containing the patented combination of two antifungal actives has shown good clinical efficacy and tolerability in a previous two-phase randomized controlled trial.

METHODS: A specific analysis of scalp SD-associated metabolome was conducted to identify molecular markers involved in SD symptoms, and examine the impact of the anti-SD shampoo on these compounds. The intervention scheme involved a 2-week phase of intensive product use (three times a week), followed by an 8-week parallel-group maintenance phase consisting of the test group using the study shampoo once a week, and the control group using a neutral shampoo.

RESULTS: Following the intensive phase of the intervention, a significant decrease in the levels of SD markers (cathepsin S, interleukin-8, and histamine), inflammatory lipids (arachidonic acid, linoleic acid, and oxylipins), and metabolites involved in tryptophan metabolism (indolacetate and indolelactate) was observed. These changes were sustained during the maintenance phase in the test group only, supporting the clinical efficacy of the anti-SD shampoo. The integrated analysis of metabolome and fungal microbiome data suggested a positive correlation between the level of Malassezia fungi and that of two oxylipins (9,10,13-triHOME and 9-HODE), highlighting the pivotal role of these lipolytic fungi in SD conditions, and the involvement of newly identified proinflammatory lipid mediators. These oxylipins could be used as novel targets for developing alternative anti-SD strategies.

CONCLUSION: This approach allowed us to better characterize specific interactions within the scalp ecosystem providing deeper insights and unravelling new therapeutic pathways in SD like pro-inflammatory oxylipins.

This study investigated oral and gut microbial changes in a 4-nitroquinoline N-oxide (4-NQO)-induced OSCC mouse model. After 16 weeks of 4-NQO exposure, significant alterations were observed in the beta diversity of both oral and gut microbiomes. Notably, the relative abundance of Lactococcus increased, especially in oral microbiomes, from week 6 to 16, followed by a decline at week 22, suggesting a 4-NQO-induced niche favorable to its proliferation. Absolute quantification revealed a 4-NQO-induced increase in total bacterial load in the oral cavity, accompanied by elevated absolute abundance of Lactococcus. Unexpectedly, oral administration of Lactococcus strains isolated from 4-NQO-treated mice mildly alleviated inflammation. In vitro, lysates from these strains exhibited protein-dependent cytotoxicity against murine OSCC cells. These results suggest that Lactococcus strains may exert protective effects during OSCC progression.},

Here, we investigate the impact of the root-knot nematode (Meloidogyne) on banana continuous cropping over a period of 11 years. The results show significant root infestation initially, but disease incidence declined markedly from the 7th cropping year onwards. Soil community profiling revealed that this intriguing onset of nematode suppressiveness was associated with changes in free-living nematode populations and rhizosphere microbiome composition. Rhizosphere microbiome analyses and strain isolation pinpointed Bacillus velezensis as a keystone taxon in soil suppressiveness to Meloidogyne. Genomics, metabolomics and bioassays validated the suppressive effects of B. velezensis against Meloidogyne and identified the siderophore bacillibactin as key metabolite with repellent and nematicidal activities. By integrating long-term field studies with multi-omics approaches, this study uncovered co-occurring increases in specific rhizobacterial genera and free-living nematodes associated with reduced root-parasitic nematode populations, offering valuable insights for sustainable agriculture.},

Recent scientific inquiry has substantiated the existence of the gut-brain axis; nevertheless, emerging evidence suggests that the brain and lungs engage in bidirectional communication through multiple pathways, thereby giving rise to the conceptualization of a brain-lung axis. Studies indicate the presence of crosstalk between the central nervous system and the lungs, mediated by the lung microbiome, neural pathways, metabolite signaling, and immune pathways. This bidirectional communication between the brain and lungs is further implicated in the pathogenesis of several diseases: traumatic brain injury, stroke, and other cerebral disorders can precipitate pulmonary injury; conversely, severe pulmonary conditions, such as acute respiratory distress syndrome and chronic obstructive pulmonary disease, can exacerbate neuroinflammation, intensify brain damage, impair neurological function, and contribute to adverse prognoses. Exploring the brain-lung axis not only facilitates a multifaceted understanding of disease progression, but also unveils critical targets for therapeutic intervention. Research into the brain-lung axis provides novel perspectives for deciphering underlying pathological mechanisms, developing diagnostic methodologies, and formulating treatment strategies. It further establishes a theoretical foundation for cross-organ targeted therapies, holding promise for ameliorating patient outcomes and promoting the advancement of integrated diagnostic and therapeutic approaches for respiratory and neurological disorders.},

Bacterial vaginosis was considered enigmatic with unknown aetiology, difficulty in diagnosis, different response to treatment, be that persistence or recurrence, and different phenotypic outcomes.

METHODOLOGY: A narrative review.

RESULTS: New information from the Human Microbiome Project using molecular-based, culture-independent technology has added important new knowledge to our understanding of vaginal eubiosis and dysbiosis. While this metagenomics are currently mainly research tools, we hope further studies will better elucidate the full profile of dysbiosis. This will hopefully aid the choice of antibiotic to suit each dysbiotic profile identified rather than for a single organism. By measuring abundance and diversity of the vaginal microbiome, we can develop molecular means of differentiating eubiosis and dysbiosis to predict preterm birth. We can also choose which antibiotic is appropriate for different dysbiotic subtypes, the local subtype of milieu created by that microbiota, the host response, and the phenotypical outcomes of which preterm birth is paramount. In addition, we can develop suitable probiotic species of lactic acid producing bacteria to aid in the prevention of preterm birth.},

abstract = {Neurodegenerative protein conformational diseases (PCDs) are progressive, currently incurable disorders driven by toxic protein aggregation that leads to neuronal death. Emerging evidence supports a microbial role in PCDs, including the most prevalent: Alzheimer's and Parkinson's disease. While metagenomic studies consistently associate gut dysbiosis with these disorders, the mechanisms by which microbes influence host proteostasis remain poorly understood. In particular, considerable attention has been given to proteotoxic bacteria, but the mechanisms by which commensal microbes confer proteoprotection remain largely unexplored. We have previously employed Caenorhabditis elegans models to characterize the role of over 220 bacterial isolates on host proteostasis. Strikingly, members of the Prevotella genus exhibited proteoprotective effects. Most notably, transient exposure to P. corporis uniquely induced Hsp70, a critical molecular chaperone that maintains proteostasis, and significantly reduced aggregation of polyglutamine (polyQ), Aβ1-42, and α-synuclein. In the present study, we expand on these findings, demonstrating that among 13 Prevotella species tested, P. corporis robustly activates the heat shock response (HSR) and confers conserved aggregate-suppressing activity in Drosophila melanogaster. We further demonstrate that transient exposure to P. corporis results in the activation of protective stress pathways and promotes disaggregation of existing intestinal polyQ aggregates in C. elegans, leading to a general enhancement of global proteostasis. This is supported by significantly improved survival and enhanced thermotolerance. Together, our findings reveal a beneficial niche for P. corporis in activating the HSR to enhance organismal proteostasis and support a microbe-mediated gut-proteostasis axis. This work underscores the therapeutic potential of targeting the gut microbiota for the management of PCDs, highlights the importance of species-level resolution in microbiome studies, and supports the emerging view of the intestine as a proteostasis-modulating organ.},

abstract = {The aim of this study was to evaluate the effect of Fructus Ligustri Lucidi (FLL) supplementation on energy metabolism, immunity, and the rumen microbiome in peripartum cows. Twenty healthy multiparous Holstein dairy cows were enrolled in the trial based on expected calving date, parity, and previous lactation milk yield. They were randomly assigned to either a control diet (Con; n = 10) or the control diet supplemented with 150 g/d per cow of FLL (FLL; n = 10). The trial spanned 6 wk, from 3 wk prepartum to 3 wk postpartum. Cows were milked thrice daily at 0500, 1100, and 1700 h, with milk yield and SCC recorded. Blood samples were collected from each cow at -3, -2, -1, 0, 1, 2, and 3 weeks relative to calving to evaluate the metabolic, inflammatory, and oxidative profiles. Peripheral blood neutrophils were isolated to measure reactive oxygen species (ROS), phagocytic activity, and neutrophil extracellular traps (NET). Rumen liquid was obtained via esophageal tubing at -3, 0, and 3 wk to investigate microbial biodiversity. Results indicated that FLL supplementation did not significantly affect the milk yield or SCC within 3 wk postpartum. Notably, FLL ameliorated negative energy balance from 1 wk to 3 wk, mitigated inflammation from calving day to 3 wk, and reduced oxidative stress at both -1 and 1 wk. The FLL treatment enhanced neutrophil phagocytosis from calving day to 1 wk, increased NET release at -1 wk, and reduced neutrophil ROS levels on calving day. Moreover, FLL increased rumen microbial α-diversity on calving day. At the phylum level, Firmicutes abundance was higher in the Con group on calving day compared with 3 wk pre- and postpartum, whereas Bacteroidota exhibited the opposite trend; FLL maintained stable Firmicutes and Bacteroidota abundances throughout the peripartum period. At the genus level, Prevotella abundance decreased in both groups on calving day but rebounded by 3 wk, with significantly higher Prevotella levels in the FLL group on calving day. The level 2 Kyoto Encyclopedia of Genes and Genomes pathway prediction further indicated divergent metabolic profiles: lipid metabolism pathways were less active in the FLL group than in the Con group on calving day and at 3 wk, whereas immune-related pathways were enriched in the FLL group. Energy metabolism pathway activity was higher in the FLL group on calving day but lower by 3 wk compared with the Con group. Correlation analysis indicated that rumen microbiome shifts were associated with energy metabolism, immunity, and oxidative stress. In conclusion, this study elucidates the dynamic changes in rumen microbiome during the peripartum period and highlights the beneficial effects of FLL supplementation on energy metabolism, immune function, and rumen microbial homeostasis in peripartum dairy cows.},

abstract = {Traditional fermented dairy products constitute a rich reservoir of probiotics and are closely associated with the maintenance of gut microbiome homeostasis and host health. However, the diversity and functional properties of probiotics in these products remain incompletely characterized. In this study, we aimed to isolate and identify novel probiotic strains from traditional fermented dairy products and systematically evaluate their probiotic attributes and mechanisms of action. Three previously uncharacterized strains-Lacticaseibacillus rhamnosus L.r1, Lacticaseibacillus rhamnosus L.r2, and Lactiplantibacillus plantarum ssp. plantarum L.p-were isolated and identified. Their probiotic features were assessed through acid and bile salt tolerance tests, survival in simulated gastrointestinal fluids, cell surface hydrophobicity, and autoaggregation capacity. Additionally, cell-free supernatants from these isolates exhibited broad-spectrum antimicrobial activity against several pathogenic bacteria. Whole-genome sequencing and comparative genomic analysis revealed the presence of an LPH homolog gene implicated in anti-inflammatory processes, along with gene clusters encoding secondary metabolites such as RiPP-like and terpene-precursor compounds. In a dextran sulfate sodium-induced murine colitis model, administration of L.r1, L.r2, or L.p significantly ameliorated colon damage, upregulated the expression of ZO-1, occludin, and IL-10, and downregulated IL-6. Fecal microbiome sequencing and functional prediction indicated that intervention with these strains restored gut microbiota balance, promoted the enrichment of beneficial genera including Akkermansia, Pediococcus, and Bacteroides, and suppressed microbial pathways related to antibiotic resistance and carbohydrate transport. These findings demonstrate that the isolated strains alleviate colitis through multifaceted mechanisms and hold strong potential as next-generation probiotics, providing both a theoretical foundation and microbial resources for developing functional foods.},

abstract = {Large amounts of microplastics (MPs) are transported annually from river into the ocean. Biofilm-covered MPs, termed as the "plastisphere", may mediate microbial transfer. Previous studies have mostly focused on the evolution of the plastisphere itself, covering field experiments and its transformation during migration. Direct evidence for their impact on marine communities is still limited. To address this, we combined field and laboratory experiments to directly evaluate the effects of MPs on marine microbial communities along the river-sea shift. MPs were incubated for 0, 28, and 140 days in freshwater. They were then transferred to a laboratory-simulated marine micro-ecosystem constructed with a fresh seawater microbiome to allow the microbial communities to acclimate, and then further incubated in the laboratory for 1, 3, and 7 days. Microbial community dynamics were examined using metagenomic analysis. Long-term incubated plastispheres (140 days) rapidly shifted marine community structure toward plastisphere-like composition as early as Day 1. However, this overall structural change faded by Day 7. Interestingly, the presence of 28-day and 140-day plastispheres led to a consistent increase in microbial species diversity and a higher number of antibiotic resistance genes (ARGs) and virulence factors (VFs), this effect persisted through Day 7. Additionally, salt-tolerant, potentially pathogenic bacteria were also detected, reflecting the as carrier roles of plastispheres. This study provides direct evidence that plastispheres mediate microbial transfer, thereby enhancing diversity and spreading ARGs and VFs, contributing to a better understanding of the potential ecological and environmental risks of microplastics.},

While conventional infertility evaluations, encompassing medical history, ovulation assessment, uterine and tubal evaluation, genetic screening, hormonal profiling, and reproductive tract imaging, provide essential diagnostic information, a substantial proportion of infertility cases remain unexplained, prompting increased attention to microbial factors. This review provides a comprehensive, critical evaluation of methods for assessing the female reproductive microbiome, spanning traditional culture-based microbiology to contemporary molecular approaches. We systematically discuss the diagnostic performance, clinical utility, and established techniques, including microscopic examination, Nugent scoring, and Amsel criteria, alongside modern molecular methods such as quantitative PCR panels, 16S rRNA gene sequencing, shotgun metagenomics, and other multi-omics. Critically, we evaluate the current microbiome testing platforms in clinical validity and utility. We identify significant gaps between research-grade methodologies and clinically actionable diagnostics, including a lack of standardized protocols, inconsistent reporting of absolute bacterial loads versus relative abundances, and limited validation against reproductive outcomes. We propose evidence-based criteria for selecting appropriate diagnostic approaches based on clinical context and discuss emerging technologies, including multi-omics integration for implementing microbiome assessment in fertility care.},

abstract = {Historically, it was thought that primary steroids released from endocrine glands exert their hormonal effects through corresponding receptors in peripheral tissues, and that their metabolism then inactivates them, followed by excretion. However, the metabolism of primary steroids is not just a way of inactivating and excreting them, but generates a variety of metabolites with different biological properties. In this review, we outline how various active steroid metabolites were discovered, describe some of the ways they are generated, and how they can in a non-classical way act on receptors or alter the activity of steroid metabolizing enzymes, thereby indirectly affecting receptor activities. Examples include the 5α-reduced ring-A metabolites of 11-deoxycorticosterone (DOC) and progesterone that are formed in the brain, act as neurosteroids and exert effects through the GABA-A membrane receptor. Another example is 11-ketoprogesterone that potently activates mineralocorticoid receptors (MR), but not glucocorticoid receptors (GR), and is more potent than its 11β-hydroxylated form, in contrast to glucocorticoids. Moreover, we discuss the microbiome as important source of bioactive metabolites, exemplified by the 11β-hydroxylated 5α-reduced ring-A corticosteroid and progesterone metabolites that were shown as potent 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2) inhibitors. 11β-HSD2 inhibition results in cortisol-induced MR activation, sodium retention and hypertension. Furthermore, microbial 17,20-desmolase activity can convert glucocorticoids to androgens, potentially influencing diseases and therapeutic outcomes. There are still many knowledge gaps regarding bioactive steroid metabolites. Identifying additional bioactive steroid metabolites and characterizing their genomic and non-genomic effects should help uncovering their cell-specific functions and contributions to the maintenance of homeostatic regulation.},

Oak trees hosted distinct microbial communities across tissue types, which remained largely stable under stress. Rain exclusion significantly altered microbiota composition, though these changes explained less than 1% of total variance. Actinobacteriota, linked to drought tolerance, increased in the root/rhizosphere of rain-excluded trees.

abstract = {OBJECTIVE: The rumen microbiota plays a pivotal role in fermenting plant biomass, which is essential for nutrient conversion. Although extensive research has examined the intestinal microbiome of Tibetan livestock, the rumen microbiota of semi-fine wool sheep (SF-sheep) remains poorly characterized. This study aimed to profile age-related changes in the rumen microbiota and fermentation parameters of SF-sheep to uncover potential microbial-mediated adaptations to different growth stages.

METHODS: Full-grazing male SF-sheep were randomly assigned into three age groups: two-month-old lambs, yearling sub-adults, and approximately 50-month-old adults. 16S rRNA gene sequencing and high-performance liquid chromatography were used to analyze the rumen microbiota composition and short-chain volatile fatty acids (SCVFAs).

RESULTS: Age-dependent differences were observed in ruminal NH₃-N concentrations, with sub-adult sheep exhibiting higher levels than young and adult individuals, whereas SCVFAs concentrations remained relatively stable. With age, the rumen microbial community structure tended to become more homogeneous, whereas microbial diversity and complexity showed a marked increase during adulthood. At the phylum level, Saccharibacteria and Succiniclasticum were enriched in sub-adults, whereas Euryarchaeota and Prevotellace_UCG_001 were more abundant in adults; no microbial biomarkers were detected in young sheep. Correlation analyses indicated that age and NH₃-N concentrations were the primary factors shaping the rumen microbiota. SCVFAs, including acetate, butyrate, and propionate, were positively associated with fibrolytic and polysaccharide-degrading bacteria such as Prevotella_1, Treponema_2, and Selenomonas_1. The rumen microbial communities were classified into two enterotypes. Enterotype 1, predominantly observed in young SF-sheep, showed higher abundances of KEGG Orthologs (e.g., K00656, K00239, K01966) associated with acetate, propionate, and butyrate synthesis.

CONCLUSION: The rumen microbial ecosystem of SF-sheep undergoes pronounced age-dependent restructuring in microbial composition and diversity, accompanied by nitrogen metabolism. These changes reflect dynamic microbial adaptation to the host's physiological state and potential developmental shifts in nutrient requirements, offering valuable insights for age-specific nutritional management strategies.},

abstract = {Nanostructured lipid carriers (NLCs) are promising in target and efficient delivery of bioactive compounds with high loading capacity of bioactives, better physical stability, better encapsulation efficiency, solubility and bioavailability in comparison to the conventional delivery systems for lipophilic and hydrophobic bioactives such as essential oils and phytochemicals as well as functional feed ingredients. There are different types of NLCs combining solid lipid and liquid lipid in a single nanoparticulate matrix that have advantages over other drug delivery systems. The NLCs can be synthesized in form of imperfect, amorphous, oil-enriched, surface modified or functionalized, hybrid or composite and multiple-compartment or double-shell NLCs. Moreover, the synthesized NLCs safety, efficacy, toxicity, encapsulation efficiency, drug loading and releasing capacity, reproducibility in large scale were evaluated. The application of NLCs for the effective and target delivery of bioactive compounds are widely reported in biomedical and therapeutic studies. However, utilization of NLCs for the effective delivery of bioactive compounds is very limited in swine and poultry health. There are some recent studies reported that NLCs with can enhance growth, antioxidant capacity, immunity, gut health and microbiome as well as disease resistance in swine and poultry. This review focuses on recent developments and future prospects of utilizing NLCs in swine and poultry health management. Regardless of the potential beneficial effects of NLCs in nanodelivery of bioactive compounds, further research on long-term field oriented studies in livestock and poultry farms and economic analysis of manufactured NLCs should be carried out.},
