Developing human skin has immune cells with memory-like features.

This chapter reviews cultural practices and morphological differences in ethnic hair, relating them to specific disorders seen in these populations, without presenting new clinical results.

This study suggests that keratin 9 expression in nonpalmoplantar keratinocytes can be induced by signals from palmoplantar fibroblasts, potentially enabling the use of nonpalmoplantar epidermis to treat palmoplantar wounds.

This study found that the Hr gene loss and positive selection for the FGF5 gene in cetaceans likely contributed to hair loss as these animals adapted to aquatic environments.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.

The researchers reported that sulfated chitosan-containing sponges can modulate macrophage activity in diabetic wounds, reducing inflammation and promoting angiogenesis and tissue regeneration, which may enhance wound healing outcomes.

In this study, researchers used NIH hairless mice to uncover genetic markers associated with hair loss and identified a Lama3 point mutation as a potential genetic contributor, creating a mutant mouse model that may advance the study of androgenetic alopecia.

This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

In this study, researchers found that using bioinspired nanovesicles derived from inflammation memory-activated epidermal stem cells effectively promoted healing in diabetic wounds by reprogramming neutrophils to an anti-inflammatory phenotype in both laboratory and animal models.

This study reported that the Undiagnosed Disease Program at Ghent University Hospital successfully provided definite diagnoses for 18% of referred adults with suspected rare diseases, primarily through genomic technologies.

This study identified genetic variants in the DSG4 gene associated with the autosomal recessive form of monilethrix in Chinese patients, expanding the understanding of its phenotypic spectrum and clinical features.

The K15 promoter effectively targets stem cells in the hair follicle bulge.

This study systematically reviewed clinical findings in trichothiodystrophy patients and suggested a new clinico-genetic classification to help better understand the ichthyotic phenotype and its management.

This study found a significant association between reduced FGF13 levels and X-linked congenital generalized hypertrichosis, suggesting FGF13's potential role in hair follicle growth and the hair cycle.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study found no significant difference in polycystic ovary syndrome prevalence between lesbian and heterosexual women seeking artificial insemination, nor in their fertility rates.

This study found that macrophages treated with keratin in vitro were more similar to anti-inflammatory M2 macrophages and reduced astrocyte reactivity, potentially limiting secondary inflammatory damage after spinal cord injury.

This study shows that differences in Hoxc gene expression in hair follicle mesenchyme along the body axis contribute to regional variations in mammalian hair growth.

Aged skin cells can help hair growth by stimulating stem cells.

In this study, researchers used proteomics to analyze hair samples from diverse ethnic populations, finding that hair protein profiles could potentially distinguish individuals based on ethnicity, sex, and age, offering a new method for human identification in forensic science.

In this case-control study, researchers observed that smoking and lighter hair color significantly increased the risk of developing androgenetic alopecia, with older individuals and women showing higher prevalence rates, while hair thickness and shape were not linked to increased alopecia risk.

This article reports the first documented cases of Marie-Unna hereditary hypotrichosis in Egypt, highlighting the variability of genetic mutations in this rare form of congenital hair loss.

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 injecting nu/nu mice with aqueous dispersion of unmodified fullerene C60 significantly stimulated hair growth compared to controls, suggesting its potential as a new therapeutic approach for alopecia.

This study found that mice with a mutation in the Zdhhc13 gene exhibited increased susceptibility to skin cancer, highlighting a potential protective role of palmitoyl acyltransferase in skin carcinogenesis.

This chapter reviews differences in dermatological treatments and conditions between male and female patients, particularly noting the impacts of sex steroids on various skin processes, but presents no new clinical findings.

This study found that nanofibers combining a polydopamine coating and curcumin nanocrystals were effective in treating diabetic wounds infected with methicillin-resistant Staphylococcus aureus by providing sequential photothermal antibacterial action and promoting M2 macrophage polarization, which accelerated wound healing through enhanced angiogenesis and cell proliferation.

This study identified differences in adverse symptoms among patients with post-finasteride syndrome based on short and long androgen receptor gene polymorphisms.

This review discusses sex differences in immune response to respiratory viral infections, including SARS-CoV-2, and highlights that hormones like estrogen may provide females with better protection, but it reports no new results.
