This research highlighted that the gut microbiota may influence ovarian health, suggesting it could be used as a biomarker for early diagnosis and treatment of diseases like PCOS, ovarian insufficiency, and ovarian cancer due to its impact on hormone levels.

This study found that Hashimoto's thyroiditis and alopecia areata show distinct gut microbial patterns, with specific microbes like Bacteroides fragilis and Microbacterium sp. T32 potentially linked to autoimmune activity.

In this study, supplementing low-protein diets with 0.75% methionine maintained growth performance, improved fur quality, enhanced nutrient utilization, and supported intestinal microbiota balance in blue foxes, with significant results on several biochemical parameters and nutrient digestibility observed.

This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

This study suggests that cedrol may improve mitochondrial function, gut microbiota, and intestinal barrier integrity, indicating its potential value in treating inflammatory bowel disease.

This study identified peripheral myeloid cells as the earliest dysregulated immune cells in PINK1 KO mice with Parkinson’s-like symptoms following intestinal infections, suggesting that PINK1 regulates gut immune functions linked to early Parkinson’s disease mechanisms.

This study demonstrated that dietary cupric citrate improved growth performance and nutrient utilization in broilers, while also altering their intestinal microbiota and increasing the pH in the duodenum and jejunum.

In this review, researchers examined the physiological benefits of Cheonggukjang, a salt-free fermented soybean paste, highlighting its various health-promoting components that may contribute to improved heart health, diabetes management, and cancer prevention, among other benefits.

This study found that PGRP-S expression in mouse epidermis is specific to certain hair follicle epithelia, depending on the skin region, and can be transiently induced in flank skin hair follicle epithelium after exposure to Staphylococcus aureus, suggesting a role in environmental surveillance.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This review discusses the importance of omega-3 fatty acids for human health and explores recent advancements in genetically modifying plants to produce these essential nutrients, but reports no new results.

This article discusses the role of the microbiome in different forms of alopecia and highlights the importance of Omics approaches for future research, but it provides no new clinical results.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.

This review discusses the use of microbial biosurfactants as a safer alternative to chemical surfactants in cosmetics due to their antibacterial, moisturizing, and low toxicity properties, but it reports no new clinical findings.

This review evaluates the potential of natural products from marine microorganisms for cosmetic applications and reports no new experimental results, highlighting challenges and prospects in their use.

This study demonstrated that metabolomics could identify persistent biomarkers distinguishing between heavy ion and γ radiation exposures, offering a potential tool for assessing long-term radiation risk for intestinal pathologies.

Women have a higher DHT/testosterone ratio than men, possibly due to gut bacteria activity.

This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.

This study found that male germ-free rats fed semisynthetic diets do not grow as rapidly as their conventional counterparts and require dietary biotin for normal metabolism and folic acid biosynthesis.

This review highlights that the skin microbiota plays a crucial role in wound healing, with beneficial microorganisms aiding tissue repair and opportunistic pathogens hindering it, potentially guiding future microbiome-targeted therapies.

This study found that tea polyphenol–zinc significantly improved intestinal barrier function and reduced liver inflammation and oxidative stress in mice with diquat-induced damage.

This study introduces MicrobeFDT, a tool that clusters chemically similar compounds and links them to gut microbial enzymes and toxicities, demonstrating its utility by uncovering previously unknown metabolism of the cancer drug altretamine.

This research found significant associations between gut microbiome composition and 14 out of 37 examined health conditions, suggesting that increased microbial abundance often aligns with favorable health states.

This review reports that Fenugreek seeds contain compounds like Galactomannan and Trigonelline, which show anti-diabetic and anti-hyperlipidemic effects, while Fenugreek leaves have high saponin content, contributing to their anti-microbial activities.
