In this study, engineered skin substitutes containing murine dermal papilla cells developed hair follicle-like structures when grafted onto mice, suggesting a model for generating chimeric hair.

This study found that skin thickness in Bakerwali goats increased with age, with notable histological differences in these layers across diverse regions of the body.

This review of murine studies reports that γ-rays affect hair follicle pigmentation in mice throughout the hair cycle, while effects on hair structure may be obscured by aging.

This study found that down and guard hairs of Inner Mongolia Cashmere Goats have distinct protein compositions and physical properties, with keratin-related proteins potentially influencing these differences.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

The study reported that combining the Follicular Closing Technique with the Franz diffusion cell is a valuable method for investigating follicular caffeine penetration in vitro, though kinetics differ from in vivo results.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This study reports that a new nude allele, nu(StL), encodes a truncated Whn transcription factor affecting T-cell development and keratin gene expression, with notable differences from the original Whn(nu) mutation.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.

This study found that Bakhtiari sheep hair fibers and follicles became larger and more organized with age across all skin regions, with no significant differences by sex.

This study presents the first report on cloning and characterizing the full-length cDNA of SRD5A1 in Indian catfish (Clarias magur), revealing expression differences across reproductive phases and increased expression post-Ovatide administration in ovaries and testis.

This study suggests that Demodex mites might universally inhabit adult humans, with a phylogenetic analysis indicating potential undiscovered lineages of the D. brevis species based on geographic differences.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.

This study found that age-related cues, such as perceived appearance, clothing, and family structure, may influence health outcomes and longevity in different ways.

In this review, the authors discussed how men seek cosmetic procedures for distinct reasons compared to women, emphasizing the need for dermatologists to consider male-specific desires for discrete treatments with minimal downtime and differences in psychological motivations.

This study discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.

In this pilot study, topical latanoprost acid was observed to increase hair count and improve hair follicle structure in women with androgenetic alopecia, with no serious adverse events, suggesting potential for further investigation to confirm its efficacy and safety.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This study suggests that CD151-integrin complexes inhibit epithelial cell migration, and that disruption of these complexes enhances migration, regulated by Rho GTPase activation differences on distinct laminins.

In a randomized clinical trial, Robinson et al found that patients with melanoma and their partners could effectively perform skin self-examinations after participating in a 30-minute structured skills training, potentially aiding early detection of additional melanomas.

This review discusses factors contributing to COVID-19 severity disparities, highlighting age, comorbidities, race/ethnicity, and gender, and reports no new clinical findings; it emphasizes understanding these mechanisms to address risk differences.

This article questions whether frontal fibrosing alopecia and fibrosing androgeneic patterned hair loss are overlapping conditions or stages of the same process, calling for further research to clarify their underlying factors.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

In this study, researchers created a new molecular salt from minoxidil and 2,4-dihydroxybenzoic acid, finding it superior to raw minoxidil for promoting hair growth in a mouse model, suggesting it may be a promising candidate for treating hair loss.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

In this study, researchers found that the original four-factor model of causal illness attributions in the IPQ-R did not fit a Chinese sample, and instead identified a two-factor model focusing on psychological attributions and risk factors.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

This case report highlights the simultaneous presence of white piedra, identified as T. inkin, and pediculosis capitis in one patient to emphasize their clinical distinctions.
