This article reviews fetal scalp hair formation and related disorders but reports no new research results.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This review provides an overview of the physiologic skin changes during pregnancy but reports no new findings, emphasizing the need for physicians to distinguish between benign and potentially pathological conditions.

This study suggests that daughters of women with PCOS may have altered androgen metabolism in early childhood, with increased 5α-reductase activity potentially contributing to PCOS development.

This study demonstrates the use of the CRISPR-Cas9 system to successfully edit the EDAR gene in Cashmere goats, resulting in goats with distinct hair follicle characteristics.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This article reviews the characteristics, diagnosis, and management of premature adrenarche and suggests it may predict future ovarian hyperandrogenism in some adolescents; no new clinical results are reported.

This review discusses the physiology of hair follicles, their disorders, and the principles behind developing treatments, reporting no new results.

This study found enhanced remyelination in the corpus callosum of late pregnant rats compared to virgin and postpartum rats, suggesting a pregnancy-associated promyelinating effect mediated, in part, by the GABA A receptor system.

This review proposes a classification system for childhood hair loss based on clinical appearance, age of onset, and associated symptoms, but reports no new clinical results.

Finasteride temporarily lowers male rat fertility without affecting libido.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This review discusses diagnostic challenges and management approaches for pediatric hair disorders, emphasizing the importance of distinguishing between acquired and congenital conditions, and reports no clinical results.

Women's ovarian hormones and adrenal androgens change throughout life, affecting hair loss and health.

This study reports that the burden of PCOS was higher among urban Indian adolescent females compared to their rural counterparts.

This case report describes hair regrowth in a patient with alopecia totalis using fluocinolone acetonide cream applied under thin plastic films.

This meta-analysis found that chromium supplementation was associated with decreased insulin resistance but increased testosterone levels in women with PCOS, with no significant benefits for other metabolic or hormonal indexes.

This study observed that pregnant women with polycystic ovarian syndrome had a higher prevalence and incidence of cervical insufficiency compared to those without PCOS.

Finasteride slows down motherly behavior in first-time pregnant rats.

This study found that maternal Nano-Se supplementation in cashmere goats improved antioxidant status and promoted secondary hair follicle development in fetuses at 110 days.

This article compares the immunology of cancer and the placenta and suggests that immunotherapy for pregnant cancer patients could be feasible with careful exploration, though no new clinical results are reported.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This study found that keratinocytes show increased expression of the TGF-β system and collagen type I with age, suggesting a heightened profibrotic response during skin differentiation associated with scarring.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This review discusses treatments for female acne, highlighting the effectiveness of low-dose oral contraceptives and noting their similar side effects to placebo; it reports no new clinical results.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

This article discusses the need for a globally standardized protocol for epidemiologic studies of polycystic ovary syndrome to improve study comparability and public health policy.

This case report describes an 11-month-old boy with Menkes disease, highlighting symptoms such as developmental delays and poor therapeutic response due to significant brain and vascular abnormalities.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

This study identified a severe MBTPS2 gene mutation in a Japanese patient with IFAP syndrome, suggesting other factors may influence the varied clinical severity of the condition.
