This review discusses the protective effects and mechanisms of melatonin in skin and suggests potential therapeutic applications in cutaneous medicine, reporting no new clinical findings.

This study identified two cell surface markers, FAP and CD90, that distinguish between papillary and reticular fibroblasts in human skin, suggesting distinct functions and distribution in dermal layers.

This study found that DrugNet, a network-based prioritization method, effectively improves drug repositioning tasks, achieving high performance in validation tests and clinical trial comparisons.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.

This study found that severe zinc deficiency induced in weanling rats led to growth retardation, hair issues, and dermal lesions, all of which were completely reversed by zinc supplementation.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This study observed that hair cortisol and cortisone concentrations were higher in older individuals and those with diabetes mellitus, highlighting their potential significance for assessing somatic health.

In this retrospective cohort study, researchers reported that 11.5% of patients with DRESS developed significant long-term autoimmune or renal sequelae, with age influencing the type of sequelae observed.

This study found that cosmetic hair treatments like bleaching and dyeing significantly reduced drug concentrations in hair samples, with decreases ranging from 30% to over 60% depending on the treatment and hair damage level.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This guideline review discusses updated evidence-based recommendations for managing tinea capitis, with a focus on accurate diagnosis, effective treatment, and prevention strategies, but reports no new clinical results.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study found that benign tumors with a high risk of malignant progression primarily arise from hair follicle cells when a mutant ras gene is expressed in a specific population of epidermal cells in mice.

This review discusses the development, regulation, and aging of the human hair follicle pigmentary system and suggests potential for reversing hair graying by manipulating follicle melanocytes in vitro, but reports no clinical results.

This study presents evidence that keratitis–ichthyosis–deafness syndrome is caused by a mutation in the connexin 26 gene, expanding the gene's known involvement in various disorders.

This review discusses various nanoparticles and nanoemulsions being investigated for transdermal drug delivery and reports no clinical results; it highlights potential applications in treating alopecia, wound healing, psoriasis, and melanoma.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

This guideline reviews the diagnosis of androgenetic alopecia and offers expert consensus recommendations tailored to males, females, and adolescents, but reports no new clinical results.

This article compares two rare genetic diseases, vitamin D-dependent rickets type 1 and type 2, focusing on their similar presentations of hypocalcemia and rickets in infancy, but reports no new clinical results.

This review discusses three decades of progress in feather development, regeneration, and evolution, with no new experimental results; it highlights feathers' potential as a model for morphogenesis studies.

This study found that hair follicle-derived dermal stem cells and bone marrow mesenchymal stem cells have similar growth, differentiation capabilities, and surface marker expressions, suggesting hair follicles could be accessible sources for mesenchymal stem cells.

In this retrospective cohort study, women with polycystic ovary syndrome showed high incidence and age-specific prevalence rates of type 2 diabetes, myocardial infarction, and angina, particularly in those over 65.

This study suggests that mNotch expression plays a significant role in hair follicle differentiation and cell fate selection within the follicle during development.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.
