This case report identified drug-induced lung disease caused by minoxidil in a patient initially misdiagnosed with hypersensitivity pneumonitis, stressing the need for accurate medication history.

The study found that growing dermal papilla cells in 3D spheroids enhances their activity with hair growth-promoting agents, such as minoxidil and TCQA, compared to traditional 2D cultures.

This study found that rubbing increased caffeine permeation into skin primarily via hair follicles, especially when applied against the natural hair direction.

This study reveals that basement membrane composition and structure in mouse hair follicles are specialized for distinct inter-tissue interactions, with laminin α5 being essential for maintaining these interfaces.

This study found that donor sites with higher hair density and thicker hair diameter had a better appearance after follicular unit excision in men with androgenic alopecia.

This review discusses the role of biotin in metabolism and the consequences of its deficiency, reporting no new clinical results.

This study found that non-cutaneous melanocytes in mice are less sensitive to Kit signaling compared to cutaneous melanocytes, showing dependence on ET3 and HGF signaling.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

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.

A JAK1 variant causes hair loss, skin issues, and thyroid disease, but treatment with a specific inhibitor can help.

This study found that Botryococcus terribilis ethanol extract significantly reduced inflammation markers in LPS-stimulated RAW264 cells, potentially via Axl inhibition and alteration of immune-related gene expression.

This study found that dihydrotestosterone treatment in female rats altered anterior pituitary gland gene expression, with significant repression of prolactin and inhibition of GnRH receptor gene expression, suggesting specific hormone production changes.

This study found cutaneous keratinic amyloid deposition in dogs and identified cytokeratin 5 as an amyloid precursor protein, revealing new insights into the etiology of cutaneous amyloidosis.

This study found that rubbing significantly increased skin permeation of caffeine but not rhododendrol, with the direction of rubbing playing a crucial role in caffeine's enhancement.

This chapter reviews the biology and regulatory mechanisms of epidermal stem cells, emphasizing their heterogeneity and roles in skin homeostasis, cancer, and aging, without reporting new findings.

This study reports the first case of ovarian mature cystic teratoma linked to clinical virilization due to ectopic testosterone production, possibly from overexpression of the enzyme HSD17B5.

This chapter reviews the hair follicle's role in drug and chemical penetration through the skin but does not present new experimental findings.

This study found that intradermal reactivity to histamine in dogs varies with time of day, and glucocorticoids may influence this variation.

This case report describes a 46-year-old Japanese man with syphilitic alopecia and HIV who showed rapid improvement and hair regrowth after taking ampicillin.

This letter to the editor presents a case of non-Herlitz junctional epidermolysis bullosa associated with a COL17A1 mutation and reports no new clinical findings.

This study suggests that scalp massage may reduce stress, as indicated by decreased salivary cortisol and increased secretory immunoglobulin A, and improve comfort by reducing physical fatigue and negative emotions.

In this study, lysocellin induced G1 phase arrest in human osteosarcoma cells, but diminished the cytotoxic efficacy of etoposide, while its derivative alopestatin may reduce etoposide-induced alopecia in a rat model.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

This study investigated the impact of container-tip design and hair density on the scalp delivery of minoxidil in topical formulations, finding that higher hair density reduced delivery, particularly with larger tip containers, indicating the importance of these factors in product design.

This study found that water extract of olive leaf may enhance markers linked to epidermal and dermal stem cell activity and potentially improve skin aging, especially in individuals who do not exercise regularly.

This study found that kukui nut oil (AMS oil) promotes hair growth in human hair follicle cultures by increasing PGF2α levels and activating Nrf2 signaling, and a human trial confirmed its efficacy in enhancing eyelash growth.

This research observed that translation initiation shifts from cap-dependent to IRES-mediated pathways varied across tissues and cell types under stress and differentiation conditions in mice, with low IRES/Cap ratios signaling high stemness and potential multipotency, mediated by the RNA processing protein PTBP1.

In this study, a new formulation of human placental extract showed antioxidant and neurite outgrowth activities, significantly reduced hair graying in mice, and alleviated neuropathy symptoms, suggesting potential therapeutic benefits.
