This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This study found no significant difference in CUX1 core promoter methylation levels between different lambskin patterns in Hu sheep, suggesting other mechanisms influence CUX1 expression related to hair follicle development.

This study found that deleting the ATR gene in adult mice led to rapid onset of age-related traits such as hair graying and osteoporosis through reduced regenerative capacity.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This review discusses the various common, rare, and unusual skin manifestations of lupus erythematosus and highlights the importance of accurate diagnosis, but it reports no new clinical results.

This review examines dermatological side effects of taxane chemotherapy reported in past studies and highlights the necessity for identifying and managing these conditions to maintain cancer patients' quality of life; it presents no new clinical results.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.

This article reviews the role of skin surface lipid in mediating environmental stressors and discusses potential therapeutic interventions, reporting no new experimental findings.

This review discusses the potential link between smoking and hair loss and suggests that raising awareness about this association could enhance anti-smoking education efforts.

This study highlights that prolonged voriconazole use is linked to an increased risk of aggressive cutaneous malignancies like squamous cell carcinoma, necessitating careful monitoring of drug levels to manage adverse effects.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review discusses the various skin manifestations associated with end-stage renal disease and their potential causes but reports no new clinical findings; the authors emphasize pruritus as a significant condition.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This article discusses a proposed "Darwinian" model of carcinogenesis and emphasizes that cancer prevention involves more than avoiding mutagens, as gene-environment interactions are complex and non-linear.

Minoxidil slows fibroblast growth and collagen production, potentially treating keloids, hypertrophic scars, and connective tissue disorders.
