This study found that while genetic ancestry affects physical appearance traits in Latin American populations, it accounts for only a modest portion of the observed variation.

This study found high levels of toxic heavy metals in water sources of mining communities in Abakaliki, Nigeria, posing potential health risks including Parkinson's and Alzheimer's diseases.

This review discusses the role of the TOR pathway in aging and suggests that rapamycin could potentially target age-related diseases, but reports no new clinical results.

This review examines various methods for assessing hair growth in women, highlighting the usefulness of the mFG visual scoring method for diagnosing hirsutism despite its limitations.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This article outlines the rationale, design, major findings, and updated objectives of the ongoing Rotterdam Study, without presenting new research data.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review explores androgen metabolism in the skin, highlighting enzyme localization and potential implications for treating androgen-dependent skin conditions, but it reports no new clinical results.

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

This study found that the prevalence of polycystic ovary syndrome was 16.6% with Rotterdam criteria but decreased to 6.3% or 8.5% when using alternative criteria involving antral follicle count or anti-Müllerian hormone.

This study found that a basal 17-hydroxyprogesterone level is effective for screening nonclassic adrenal hyperplasia in women, with a 4 ng/mL cutoff providing high specificity and positive predictive value.

This article suggests using only firm criteria to diagnose polycystic ovary syndrome in adolescents, due to the evolving nature of its features during this period.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

This study found that lifestyle interventions improved body composition, hyperandrogenism, and insulin resistance in women with PCOS, but did not affect glucose tolerance, lipid profiles, or clinical reproductive outcomes.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

This study identified 19 specific genes involved in root hair growth and morphogenesis in Arabidopsis, using a combination of computational and experimental methods.

This study demonstrated that hair follicles significantly expedite the absorption of caffeine through the skin compared to interfollicular pathways.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This review discusses the various common, rare, and unusual skin manifestations of lupus erythematosus and highlights the importance of accurate diagnosis, but it reports no new clinical results.

This review discusses various nanoparticles and nanoemulsions being investigated for transdermal drug delivery and reports no clinical results; it highlights potential applications in treating alopecia, wound healing, psoriasis, and melanoma.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This review discusses the pathogenesis, clinical presentation, diagnosis, and treatment of cutaneous lupus erythematosus, reporting no new clinical findings.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This study found that reduced cytokinin levels allow plants to adapt to low potassium conditions by enhancing root hair growth, reactive oxygen species accumulation, and expression of a key potassium transporter gene.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This review provides an overview of recent tissue engineering and regenerative medicine developments in Asia, highlighting significant advances, representative research achievements, and discussing future directions, without presenting new research results.

This study found that approximately 75% of women with PCOS exhibited hyperandrogenemia, with free testosterone being the most frequently elevated marker.

This review discusses various treatment options for adult female acne, highlighting the need for tailored approaches due to individual patient needs and reports no clinical outcomes.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.
