In this study, a modified Ferriman-Galwey score greater than 4 was found to be effective for diagnosing hirsutism in Asian women, highlighting key areas such as the upper lip, thighs, and lower abdomen.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This study found that thyroxine increased hair growth rate in rats, but estradiol decreased it, with both hormones affecting follicular cycles independently without altering ultimate hair length.

This narrative piece considers how epigenetic factors may influence the processes of skin wound healing, including hair follicle formation, but it presents no new experimental results.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

This study observed that males aged 60 to 79 were admitted and died from COVID-19 more frequently than females, and Latin Americans were more often admitted to the ICU.

This study shows that the concentration of epidermal growth factor (EGF) is crucial for determining whether mink hair follicles are promoted or inhibited in vitro, with involvement of the Notch signaling pathway in DP cell proliferation.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study found that twice-daily intradermal injections of mouse epidermal growth factor in Merino sheep resulted in dose-dependent changes in wool follicles and fibres, including induction of catagen and subsequent regeneration.

A cancer patient died from a severe skin reaction after taking the drug cetuximab.

This study found that dual 5α-reductase inhibition in rats led to decreased sperm motility and altered morphology, resulting in subfertility.

This review discusses the role of mTOR signaling in the epidermis, emphasizing its importance in skin processes like barrier formation and wound repair, and reports no new experimental results.

This study suggests that stress-induced premature senescence of dermal papilla cells may contribute to hair follicle aging by impairing critical epithelial-mesenchymal interactions and promoting inflammatory cytokine production.

This study found that serum calcium, serum ferritin, and vitamin D3 levels were lower in students with premature graying of hair compared to controls, suggesting a potential role in the condition.

This study found that overexpression of the intercellular adhesion protein Necl2 in hair follicle stem cells was associated with reduced cell proliferation and delayed wound healing in both cultured cells and transgenic mice.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

This study found that epitestosterone acts as a weak antiandrogen by inhibiting receptor binding and 5α-reductase activity in animal models.

mTORC2 is crucial for healthy skin barrier by regulating lipids and filaggrin.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

In this study, finasteride treatment for 56 days in adult rats led to sloughing of immature germinal cells and reduced sperm content in the epididymis, indicating its importance for maintaining spermatogenesis.

This review discusses the molecular biology, diagnosis, and pathology of epidermolysis bullosa in animals and reports no new clinical findings.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.

This article discusses the cutaneous side effects of erlotinib, an EGFR inhibitor, in a patient with non-small cell lung cancer, reporting nonscarring alopecia and indicative scalp biopsy findings.

In this study, epidermal growth factor (EGF) was shown to increase the length of rat organ of Corti segments containing supernumerary hair cells, with the effect peaking at birth and independent of cell division.

This article reviews the role of polarity proteins in epidermal morphogenesis and homeostasis and discusses how their alteration may contribute to skin disease, but reports no new experimental findings.

This article reviews the diagnosis and management of inherited epidermolysis bullosa and reports no new clinical findings; it emphasizes the importance of clinical and histopathological evaluation.

This study found that reducing HDAC1 activity in the skin of mice led to defects in hair follicle structure and pigmentation, highlighting HDAC's role in skin and hair maintenance.
