This study found a significant association between gut microbiome composition and PCOS in Indian women, relating specific bacterial genera to reproductive health and metabolic indicators.

This study found that an 8-week supplementation with specific probiotic strains improved hormonal markers and oxidative stress while decreasing inflammation in women with PCOS, although clinical symptoms like acne and hirsutism showed no significant improvement compared to the placebo group.

This study observed that Indian women with PCOS had distinct gut microbiome profiles, linking specific bacterial genera to metabolic and hormonal predictors of the condition.

In a DNFB-induced mouse model of atopic dermatitis, this study found that both topical and oral formulations of the probiotic Bifidobacterium animalis J12 improved AD symptoms through distinct mechanisms, with topical applications reducing local inflammation and oral administration enhancing gut microbiota and reducing systemic inflammation.

This study reported that in laboratory conditions, a cell-free supernatant of Bifidobacterium longum BB536 promoted human dermal papilla cell proliferation and reduced damage and apoptosis caused by dihydrotestosterone, suggesting potential use as a preventative treatment for androgenic alopecia by modulating specific signaling pathways.

The study found that applying Bifidobacterium-fermented soy milk extract to human skin significantly reduced the decline in skin elasticity, suggesting its potential as a cosmetic ingredient to prevent skin aging.

This review discusses the gut-brain-skin axis and its role in skin diseases, advocating for treatments that integrate gut microbiota, mental health, and dietary interventions, but reports no new clinical results.

This study found that androgenetic alopecia involves fungal dysbiosis, with significant depletion of the commensal yeast Malassezia and enrichment of opportunistic microbes, affected by host factors and geography.

In this study, high-dose Arachis hypogaea root extract significantly reduced prostate weight and markers of glandular hyperplasia in testosterone-induced BPH in mice, with associated changes in inflammatory gene expression and beneficial shifts in gut microbiota.

This review found that microbiota-targeted interventions, particularly certain strains of probiotics, are associated with improvements in skin conditions, most notably in pediatric atopic dermatitis, but their efficacy varies across other dermatological diseases.

This review assessed dermo-cosmetic treatments using prebiotics, probiotics, synbiotics, and other biotics for acne and scalp disorders, finding potential benefits, especially with multi-strain or synbiotic formulations, although challenges like formulation stability and the need for larger trials persist.

This article discusses the potential role of probiotics and synbiotics in managing hirsutism through insulin resistance but reports no new clinical results, calling for further research.

This study suggests that the intestinal microbiota may have protective effects against celiac disease by degrading gluten and maintaining intestinal barrier integrity, but disruptions in the microbiota can exacerbate the disease.

This study found that in people with leprosy sequelae, ulcers on the lower limbs exhibited decreased microbial diversity and reduced abundance of specific bacteria compared to normal skin, with skin metabolites closely linked to these microbial changes.

This study found that berberine supplementation improved gut microbiota composition and reduced obesity-related hepatic inflammation and oxidative stress in genetically obese mice.

This study reviewed the role of probiotics in dermatological disorders and suggests they may help treat or prevent inflammatory skin conditions by modulating the microbiota, potentially reducing the need for steroids and antibiotics, though further research is needed to confirm efficacy and safety.

This review highlighted significant properties of probiotics that can promote hair growth and reduce dandruff, offering guidance for future research to scale these findings to pilot studies.

This article reviews the role of prebiotics and the potential of green tea and selenium as alternatives due to their non-toxic nature, but it reports no new research findings.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

This review discusses the relationship between gut microbiota and alopecia areata, and it does not report new clinical results.

This study found that OM-X® supplementation effectively prevented adverse biological changes caused by vitamin C deficiency in SMP30/GNL KO mice, improving energy maintenance, antioxidant capacity, and protein synthesis.

This study found that gQlab probiotics improved overall IBS symptoms, particularly in female and constipation-predominant patients, compared to placebo after 4 weeks of treatment.

This review discusses five potential mechanisms for kidney stone formation, including urinary supersaturation, Randall's plaques, sex hormones, the microbiome, and immune responses, and reports no new results.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

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

This review examines testosterone's role in male health and aging but reports no new clinical results; the authors highlight the need for further research on optimal testosterone levels to prevent age-related conditions.

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 review discusses the role of the skin microbiome in the pathogenesis of various skin disorders, such as atopic dermatitis and psoriasis, and reports no new clinical findings; it emphasizes potential therapeutic implications.

This review analyzes the molecular and genetic roles of zinc, its connection to diarrheal disease, dietary recommendations, and the impacts of zinc deficiency on health, but reports no new data.
