This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

Androgen receptors found in monkey scalps, similar to humans, affect hair growth.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

This study found that cultured hair apparatus cells initially showed low keratin antibody reactivity, which increased by day 6 as cells differentiated and corresponded with electron microscopic observations.

People with acne have more CD4+ immune cells in their skin than healthy people.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

This review discusses the clinical presentations of alopecia areata, introduces guidelines for treatment studies, and explores potential changes in cutaneous innervation, but reports no new clinical results.

This review discusses the potential efficacy of topical antiandrogen therapies for treating androgenetic alopecia and acne vulgaris, finding promising results but highlighting the need for more comprehensive studies.

In this study, researchers found no hypertrophy in axillary sweat glands of hyperhidrotic patients, with eccrine gland clear cells being the primary site of fluid transport and no evidence of apoeccrine glands.

This study found that dutasteride 0.5 mg was generally well-tolerated and led to overall improvement in male patients aged 18 to 41 with androgenic alopecia in a Korean clinical practice setting.

This article discusses the potential for topical caffeine as a natural alternative for treating androgenetic alopecia due to its ability to penetrate skin, but it reports no new clinical findings.

Dermatologists give better information on pathology forms, hypersensitivity vasculitis is a common skin issue, misdiagnoses can occur, and various skin conditions are linked to loss of elastin or genetic factors.

This study integrated single-cell RNA-seq data from four previous studies to create a comprehensive human corneal cell state meta-atlas, revealing novel marker genes, rare cell states, and distinct transcription factors, and offering a tool to enhance future cornea research.

This review discusses the potential antidepressant effects of phenylalanine, highlighting its significant activity in laboratory studies, but reports no new clinical findings.

This review analyzed current research on finasteride and dutasteride and found insufficient evidence to fully elucidate their role in metabolic adverse events, such as liver disease and diabetes, due to a lack of detailed pathophysiologic understanding; further studies are needed to clarify these mechanisms.

This review discusses the autoimmune nature of alopecia areata, potential therapeutic targets, and highlights the need for further studies on immunomodulatory treatments and genetic factors, but it reports no new clinical results.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This review indicates that many former FDA category D and X systemic dermatologic medications may negatively impact male fertility, with further research needed to assess potential teratogenic effects.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This review discusses the role of peroxisome proliferator-activated receptors and their agonists in dermatology but reports no new clinical results.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This review discusses the role of androgens in the progression of cardiovascular disease and explores novel therapeutic targets without reporting new clinical results.

This review explores the potential of periodontal ligament stem cells for regenerative therapy in periodontium, despite challenges due to their rarity, and reports no clinical results.
