This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This study concluded that the expression of specific glycoconjugate terminal sugars is developmentally regulated during rat hair follicle morphogenesis.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

This study found that in fetal skin development, both α- and β-catenins showed similar expression patterns, indicating their related roles in the development of the epidermis and skin appendages.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

In this study, researchers found that higher concentrations of internal lipids in African hair may influence its keratin structure, as observed through various analytical methods.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

This study reviewed 40 patients with scalp symptoms and identified a new variant of diffuse lichen planopilaris in 20 individuals, suggesting these conditions should be considered in similar cases.

This article reviews various updates in dermatology, including drug safety alerts and treatment options, and reports no new clinical results.

This study links scalp pruritus in lichen planopilaris and its variants to the inflammation-induced release of substance P and calcitonin gene-related peptide by sensory nerves around hair follicle inflammation sites.

In this retrospective study, researchers found that fungal infections, xerosis, eczematous dermatitis, and seborrheic dermatitis were the most common dermatological findings among patients with Parkinson's disease, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis, with significant intergroup differences observed.

This study found no association between W locus allele variations and phenotypic traits like eye color, head spotting, and fur length in Turkish Van cats, suggesting other genetic factors should be explored.

This study mapped copy number variations in Chinese fine-wool sheep, identifying regions linked to important traits like milk production and growth, and highlighting a strong selection signal at the RXFP2 gene.

This study mapped genome-wide copy number variations in Chinese indigenous fine-wool sheep, providing a valuable genetic resource for researching complex traits and genetic diversity in this species.

This study constructed a genomic map of copy number variations in fine-wool sheep, revealing their potential impact on traits like growth, nutrient metabolism, and susceptibility to selection pressures.

TGF-β is found in hair follicles and may cause hair loss in alopecia areata.

This article reviews the causes, physiology, and treatment strategies for hirsutism in women, highlighting that effective management often requires addressing underlying conditions and may involve lifestyle changes and pharmacological interventions.

This study found that lead accumulated in the hair shafts of individuals exposed to mining environments, while iron, copper, and zinc levels remained stable, highlighting the significance of SRXRF micro-analysis for environmental health research.

This study found that Fos protein expression is closely linked to epithelial cell differentiation, particularly during cornification and cell death, with overexpression observed in keratinization-blocked mutant epidermis.

This article discusses the complex pathogenesis of hirsutism and reports no new clinical results; further research is needed for better diagnostic and therapeutic strategies.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This article reviews the causes, diagnosis, and treatment options for hirsutism in females, noting its connection to conditions like PCOS and highlighting the emotional distress it can cause.

This review article concluded that combined oral contraceptive pills and antiandrogens are the most effective pharmacotherapy for improving hirsutism, while physical therapies and psychological support are essential for optimal management.

This study suggests that specific mutations in the MFN2 gene, including the p.Arg707Trp allele, can result in tissue-selective mitochondrial dysfunction leading to excessive upper body fat growth and low leptin levels.

The number of dermatologists in the US increased from 1995 to 2011, but they were unevenly distributed, mainly in urban areas, and areas with higher income and education levels.

In this study, the researchers reported that the expression of keratin 14 in the skin and hair follicles of neonatal and juvenile rats differs from that observed in adults or human embryos.

This study found that women with polycystic ovary syndrome have higher global adiposity and increased visceral fat, particularly in the ip and mesenteric depots, compared to women without androgen excess.
