This study found that women with polycystic ovary syndrome have a higher prevalence of non-alcoholic fatty liver disease and increased androgen bioavailability may be involved alongside metabolic factors.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

This study found that testosterone therapy in trans men increased facial and body hair growth while the prevalence and severity of acne peaked at 6 months but were primarily mild after long-term treatment.

This review covers the pathophysiology, diagnosis, and treatment of congenital adrenal hyperplasia due to 21-hydroxylase deficiency and reports no new findings.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.

This study found that midazolam, unlike clonazepam, increased neurosteroid levels and affected synaptic inhibition and plasticity in rat hippocampal neurons, suggesting unique actions via dual receptor activation.

This review discusses advances in protecting against chemotherapy-induced alopecia and reports no new clinical results; calcitriol and cyclosporine A emerged as promising agents in animal models with broader efficacy across multiple chemotherapy drugs.

This study found that Wnt signaling regulates the symmetric division of adult neural stem cells, increasing their numbers during subependymal regeneration, stroke response, and colony formation.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study found that inhibiting neurosteroidogenesis affected GABA A receptor-mediated synaptic inhibition in immature rats but not in adults, suggesting age-dependent modulation of synaptic strength in the spinal dorsal horn.

This study found that during late pregnancy in rats, there is an increase in extrasynaptic GABA A receptor number in granule cells of the dentate gyrus, linked to hormonal fluctuations.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This review discusses the classifications, diagnostic methods, and treatment strategies for female pattern hair loss, but reports no clinical results.

This article discusses treatment approaches for female pattern hair loss and concludes that available medical treatments are effective in reversing or stabilizing the condition in most cases of mild-to-moderate severity.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

This review discusses the drug repurposing of cardiovascular medications like aspirin and statins for new uses, including potential anti-tumor effects, noting promising experimental outcomes but less conclusive clinical trials, particularly in the field of cancer treatment.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

Vitamin D3 affects cell differentiation in specific skin areas.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This review discusses newly identified non-Edg family lysophosphatidic acid receptors, detailing their roles in vascular development, platelet activation, and hair growth, and reports no clinical results.

This study found that beta-caryophyllene enhanced re-epithelialization in cutaneous wounds of female mice, suggesting its potential for improving wound healing through multiple pathways.

This review discusses telogen effluvium, a common type of hair loss, focusing on differentiation from other conditions and potential causes, but presents no new research findings.

This paper reviews causes of hirsutism in women and emphasizes the importance of identifying underlying conditions for risk assessment, though it reports no new clinical findings.
