This study found that men with androgenetic alopecia at age 20 years may have a higher risk of developing aggressive prostate cancer, particularly advanced stage disease.

This review discusses the nutritional and medicinal benefits of breadfruit and highlights challenges in promoting its consumption, but reports no new empirical findings.

This case report describes a 46-year-old Italian woman with congenital adrenal hyperplasia who experienced significant improvements in physical and psychological health after receiving a delayed diagnosis and subsequent treatment.

This article reviews common causes of hair loss and hair excess and discusses their management in primary care settings, but it reports no new clinical results.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

Facelift surgery has evolved to focus on natural results and safety, with patient selection and postoperative care being key to success.

Cyclosporin doesn't stop hair loss.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

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 review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This study reports that BMP2 expression in goat skin is higher during late telogen and early anagen phases, indicating a potential role in hair follicle regeneration.

In this study, minoxidil was found to suppress the activity of normal human T-lymphocytes in vitro, though the physiological relevance of this effect remains uncertain.

This exchange discusses interpretations of syphilitic chancres, noting disagreement over whether multiple lesions are atypical given historical references that describe primary chancres as often being single.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

This study found that the distribution of mast cell prostaglandin d-synthase in the scalp spatially aligns with the pattern of androgenetic alopecia, suggesting a programmed vulnerability to hair loss.

This study describes a staining technique that differentiates medullary from cortical keratin in sheep and goat hair using Ziehl-Neelsen's carbol-fuchsin in skin biopsy sections.

Feathers become harder as they develop due to a change in keratin type.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

Understanding tissue self-organization can improve treatments for diseases and advance regenerative medicine.

This review explores the emotional and psychoanalytic significance of male pattern hair loss through four perspectives but reports no new clinical findings.

This study found that female Holdobaggy goslings have higher melanin content in their dorsal plumage than males, suggesting that initial plumage color can be used for sex identification.

This study found no significant genetic association between the 5α-reductase enzyme genes and male pattern baldness, suggesting a polygenic etiology rather than simple inheritance.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

In this study, researchers examined chicken feather follicle tissues from differently colored chickens and found that the genes SLC45A2 and GPNMB are involved in promoting melanin deposition, which enriches understanding of the genetic mechanisms affecting feather color.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This study identified key genes and miRNAs involved in feather morphogenesis in Zhedong White geese, highlighting a negative correlation between FOXO3 and miR-144-y.

In this study, researchers observed that fasting-induced molting in laying hens led to increased thyroid hormones, which may regulate feather molting by affecting hair follicle growth through specific signaling pathways, highlighting molecular changes during induced molting.

This article discusses treatment approaches for female pattern hair loss and concludes that available medical treatments are effective in reversing or stabilizing the condition in most cases of mild-to-moderate severity.

This study found that differences in skin transcriptomes between juvenile and adult mink, as well as between black and white mink, suggest genes regulating hair color are active during early development rather than adulthood.
