This study found that the absence of Sgk3 in mice leads to impaired hair follicle maturation, characterized by reduced cell proliferation, increased apoptosis, and premature regression.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This case report documents a rare instance of Rapunzel syndrome causing biliary obstruction in a 3-year-old girl, highlighting the importance of considering trichobezoar in cholestasis diagnosis.

This review summarizes the promising role of melatonin combined with nanosized carriers in drug delivery, suggesting enhanced effectiveness in treating various diseases compared to free melatonin.

This review examines the outcomes of treating Brazilian patients with alopecia universalis using tofacitinib and highlights the need for randomized controlled trials to determine optimal dosing and duration.

This literature review highlights the importance of understanding the mechanisms behind the gradual mosaic loss of the Y chromosome (mLOY) in men, its association with various health conditions like cardiovascular diseases and cancer, and its potential as a marker for age inference.

This review discusses the potential usefulness and safety profile of oral antiandrogens for treating frontal fibrosing alopecia, noting possible benefits but acknowledges that finasteride's efficacy remains uncertain.

This review highlights the evolution of forensic genetics from basic DNA analysis to complex genome-wide studies, enabling insights into personal traits, ancestry, and habits, and suggests future advancements through technologies like CRISPR and AI.

This study found that men aged 18-40 with moderate to severe psychosocial impairment from male androgenetic alopecia had a higher risk of sexual dysfunction.

The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

In this study, researchers highlighted that while hair lipids are crucial for hair health and protection, surfactants in shampoos and conditioners can partially remove these lipids, potentially affecting hair structure, though the exact mechanisms remain poorly understood and require further investigation.

In this study, the presence of the HPV11-E2 protein in transgenic mice was found to increase and vary the expression of a reporter gene in hair follicle bulge regions.

In this study, proteolytic enzymes applied to mice skin caused severe degeneration in hair follicles, including detachment of stem cells from their niche, suggesting potential impairment of stem cell function.

In this study, researchers found that the female plumage color variations in the common cuckoo are linked to the female-restricted genome and suggest this pattern is maintained by balancing selection, sharing ancestry with the oriental cuckoo.

In this double-blind study, a novel hyaluronic acid gel for lip augmentation was found to be as effective and safe as a commercially available gel, with similar adverse event profiles and high patient and investigator improvement ratings over six months.

This review found that while forensic DNA phenotyping and health applications for pigmentation genetics show potential, factors like phenotype definition and population diversity present challenges to accurate genotype-to-appearance predictions.

This study determined that men taking finasteride 1 mg/day exhibited significantly reduced sperm production and morphology compared to controls, although there were no notable changes in hormonal, sexual, or psychological function.

This study reviewed recent scientific evidence on the neuroendocrine and metabolic impacts of chronic use of 5-alpha reductase inhibitors, detailing its association with sexual dysfunction, mood disorders, insulin resistance, and other metabolic disorders, suggesting persistent biopsycho-social risks beyond transient side effects in users.

This study found that men taking 1 mg/day of finasteride had significantly reduced sperm production and morphology but similar hormonal, sexual, and psychological profiles compared to controls, suggesting finasteride affects semen quality without altering other physiological functions.

In this study, hair samples from dogs with chronic degenerative valve disease showed significantly higher concentrations of certain endocrine-disrupting chemicals compared to healthy dogs, suggesting a potential link that warrants further investigation.

Histopathology is crucial for accurately diagnosing eruptive vellus hair cysts.

This review discusses forensic DNA phenotyping and its potential applications, particularly for human identification in Latin American populations, but notes challenges due to genetic diversity and reports no new results.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

In this study, researchers observed that inhibiting myosin light chain kinase in hair cells reduced stiffness and oscillation in bullfrog hair bundles and increased hearing thresholds in mice.

In this study, dogs with adrenal-dependent hypercortisolism showed a decrease in the prevalence of systemic hypertension from 79% to 25% after a year of trilostane treatment or adrenalectomy, with blood pressure normalization observed by three months post-surgery in hypertensive dogs.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This study found that in participants with notalgia paresthetica, 8 weeks of treatment with difelikefalin significantly improved itch intensity and increased the rate of strict complete response compared to placebo, starting as early as week 3.

The document discusses various nail and hair disorders and their treatments.

This article discusses the effects of 1mg/day finasteride on PSA levels and its implications for prostate cancer diagnosis, reporting no new clinical results; further investigation is suggested.

This study observed that the vitamin D receptor is crucial for hair follicle formation and altering tumor development in the Wnt signaling pathway, suggesting therapeutic potential for vitamin D analogues in related tumors.
