This study describes the first case of female pseudohermaphroditism due to a novel homozygous glucocorticoid receptor gene mutation, indicating possible pre- and postnatal virilization in affected females.

This review explores the role of nutritional factors in hair loss, noting that iron and l-lysine supplementation may benefit some individuals, while excessive supplements can lead to hair shedding.

This study found that dermal papilla cells in human hair follicles exhibit stronger expression of VEGF mRNA and protein compared to other follicular cells, suggesting their key role in angiogenic processes related to hair growth.

This case report describes a 32-month-old girl with a newly identified pediatric disorder linked to a de novo mutation in the ODC1 gene, mirroring symptoms seen in a transgenic mouse model.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This review discusses the integration of omics analyses in androgenetic alopecia research, reporting no new clinical results but suggesting that collaborative multi-omics studies may enhance understanding of AGA's pathomechanisms.

This study found that isotretinoin, a drug commonly used for acne, inhibits polyamine transport in Trypanosoma cruzi, leading to trypanocidal effects, and suggests its potential as a treatment for Chagas disease without affecting mammalian cell viability.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study found that concurrent administration of cycloleucine with ethionine prevented the weakening of wool fibers in sheep, whereas reduced glutathione did not have the same effect.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

This study found that oil from CG17 garden cress seeds had higher amounts of β-carotenoids, tocopherols, and vitamins compared to other genotypes, with varying physiochemical properties across all seeds.

This study found that valproic acid and crocin, alone or together, significantly increased the expression levels of neurotrophic factors in rat-derived epidermal neural crest stem cells, suggesting therapeutic potential for neurological disorders.

This review discusses various amino acid-derived plant defensive compounds and highlights their potential as drug leads due to their potent antimicrobial properties, but reports no new experimental results.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

In this study, shampoos containing sodium lauroyl methylaminopropionate showed superior coacervate formation and lubrication on wet hair, outperforming other amino acid surfactants and suggesting potential for creating low-irritation, high-performance hair products.

This study observed elevated serum homocysteine levels in patients with psoriasis and cutaneous-oral lichen planus compared to healthy controls, but found no significant difference between the two patient groups.

This study found that good quality protein supplements or rumen-protected methionine increased fiber yield in Angora goats and, to a lesser extent, in Cashmere goats.

This study found that blue laser irradiation reduced ATP levels and cell viability in mouse skin by increasing oxidative stress through the production of reactive oxygen species.

Lacto-fermentation changes amino acid profiles in bovine colostrum, but results are inconsistent.

In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

This study found that several small molecule peptides based on thymosin β4 significantly promoted cell proliferation related to wound healing, angiogenesis, and hair growth more effectively than established positive controls.

This review discusses the potential clinical benefits and functional properties of taurine as a conditionally essential amino acid, noting its presence in energy drinks, but reports no new experimental results.

This study found a previously unreported ST14 gene mutation in a patient with ichthyosis-hypotrichosis syndrome, highlighting novel skin and hair characteristics and emphasizing the critical role of the Asp482 amino acid in matriptase activation.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

This study found that the stability of the coiled-coil structure in human hair keratin is maintained by ion-pairing and hydrophobic interactions, which are disrupted as pH approaches 7.0.

This study explored how long non-coding RNA mediates the effects of FGF5 on the hair follicle development and villus growth of Liaoning cashmere goats.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study found that adding rose hip extract to permanent wave solutions increased wave effectiveness and reduced hair damage, although variations in hair type may affect the results.
