This review discusses the molecular mechanisms involved in hair and epidermal development, highlighting how studies on human inherited diseases and mouse models have deepened our understanding; it reports no new results.

This study found that the in vitro growth of hair follicle cells, particularly papilla cells and outer root sheath keratinocytes, is influenced by different concentrations of androgens and antiandrogens.

The document concludes that ideal facial proportions are guided by specific measurements and symmetry to enhance beauty, but individual characteristics must be considered.

In this study, an unexpected premature birth of two goat kids occurred following prostaglandin administration in a timed artificial insemination protocol, with both kids exhibiting congenital abnormalities such as laryngotracheal swelling and generalized alopecia.

This chapter reviews skin manifestations in common rheumatic diseases, particularly those with polyarthritis, and offers a differential diagnosis of erythema nodosum without presenting new research findings.

A hair test can accurately predict if a person with hair loss will respond to minoxidil treatment.

This study found that fullerene nanomaterials can significantly enhance hair growth and increase hair follicle numbers in both shaved and bald mouse models, as well as in cultured human skin sections.

This study found that skin diseases were common among male Latino poultry-processing workers in North Carolina, with all workers diagnosed with at least one condition, affecting their quality of life.

This study describes a method inspired by hair transplantation techniques to efficiently isolate eccrine sweat glands from human scalp hair grafts, potentially facilitating further research into their function.

In this study, elevated prolactin and DHEA-S levels along with reduced SBP were observed in fertile non-obese women with moderate body hair compared to controls, and ethynylestradiol plus desogestrel or cyproterone acetate treatment improved clinical outcomes by increasing SBP.

In this systematic review, researchers observed that Toxoplasma gondii infection is associated with alterations in testosterone levels, generally increasing in humans but showing mixed effects in animals, highlighting a complex relationship that warrants further investigation.

In this study, AS101 combined with chemotherapy significantly reduced the severity of chemotherapy-induced alopecia in non-small-cell-lung-cancer patients and may involve immune mechanisms related to IL-1 and PGE2.

This study found that gonadal dysfunction is very common in premenopausal women with acromegaly and may be caused by hyperprolactinemia, GH/IGF-I excess, or tumor effects.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This study found that the LH response to nafarelin effectively distinguished gonadotropin deficiency from constitutional delay of puberty, performing comparably to the sleep test and offering certain advantages.

Treatment with a hormone agonist can reduce excess male hormones in postmenopausal women without surgery.

This study in cashmere goats found that DNA methylation levels were lower during hair follicle differentiation compared to induction, suggesting it plays a critical role in gene regulation for hair morphogenesis.

This study investigated the impact of prolactin and melatonin on secondary hair follicle growth patterns in Angora and Cashmere goats using in vitro methods, without reporting new definitive results.

Activin A speeds up ear hair cell differentiation, while Follistatin slows it down.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

Low-dose gonadotropin treatment is effective for infertility in women with PCOS, leading to high ovulation rates and comparable pregnancy rates with fewer complications.

This study found that untreated men with coeliac disease exhibited androgen resistance, potentially linked to sexual dysfunction, which improved as intestinal health improved, a pattern not observed in other chronic illnesses.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.
