This paper reviews the genetic aspects of hair disorders and suggests that understanding these genes could advance treatment and diagnosis; it reports no new experimental findings.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study provided the first proteome dataset for alopecia areata, revealing novel pathways in the disease mechanisms that may lead to new therapeutic targets.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

The researchers reported that minor salivary gland stem cells exhibit stem cell characteristics and respond to tobacco-derived carcinogens, implicating the transforming growth factor beta pathway in their maintenance.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

This study found that regio-specific hydroxylation of cyclosporine A in Sebekia benihana is mediated by the cytochrome P450 hydroxylase CYP-sb21, suggesting potential biotechnological applications for hair growth promotion without immunosuppressive effects.

This study found that the heat shock cognate protein Hsc70 was differentially expressed by dihydrotestosterone treatment in SV40-transformed dermal papilla cells, suggesting its involvement in androgen action on these cells.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study reported that AutoML effectively modeled itching and pain development, as well as app use, in patients with chronic eczema or psoriasis using a smartphone monitoring app, revealing that factors like BMI, age, and disease activity significantly influenced app engagement.

This study provides the first draft of the male Asiatic lion's whole genome, revealing low genomic diversity and highlighting conservation concerns.

This study found a weak positive correlation between dihydrotestosterone levels and C-reactive protein in COVID-19 patients, particularly in those with low testosterone, suggesting potential inflammatory effects.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

A botanical extract may help manage hair loss from chemotherapy by preventing cell death in hair follicles.

This study observed that the size of vaginal prolapse in patients was significantly related to both the preoperative vaginal length and the length of vaginal excision during the Michigan four-wall sacrospinous suspension procedure.

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 study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study demonstrated that in mice, the absence of Jagged-1 expression in skin-resident regulatory T cells significantly delays wound healing by reducing the accumulation of neutrophils, highlighting the role of Jagged-1 in coordinating immune cell recruitment during injury.

This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.

This study outlined modern approaches for using cosmeceuticals in trichology, emphasizing evidence-based medicine, personalized care, and patient safety. It proposed the H.A.I.R. model as a universal algorithm for trichological programs and suggested new educational and practical tools for specialists in trichology and aesthetic medicine.

This review compiles EV proteomics data and reports that while MSC-derived EVs show promise in skin therapeutics, variability in protein cargo highlights the need for standardized methodologies in understanding process impacts.
