Mouse tail skin has different keratinization near hair follicles and scales.

This report describes the first documented occurrence of Vohwinkel's disease combined with congenital alopecia universalis in siblings from the same family, both unresponsive to prior treatments.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This conference proceeding abstract provides no new research results, focusing only on event details from the British Association of Dermatology's Forty-Sixth Annual Meeting held in Oxford in 1966.

This study found that bikunin is expressed in human keratinocytes and may play a role in regulating keratinocyte function during mitosis or inflammation.

In this study, the vitamin D analogues 1 alpha,25-dihydroxy-vitamin D3 and calcipotriol were found to thin the living cell layer and affect differentiation marker expression in organotypic cultures of human outer root sheath cells.

This article reviews how various chemical agents affect human hair and skin, suggesting the need for more research on their pharmacologic and dermatologic effects; it does not report new experimental results.

This case report describes a 15-year-old Japanese girl with juvenile hypothyroidism who developed hypertrichosis and hyperkeratosis due to a keratin plug inhibiting hair growth on her back and arms.

This study developed an in vitro model using human follicular keratinocytes to observe selective cell growth and differentiation, potentially aiding future research on hair biology and growth processes.

This study found that poly(adenosine diphosphate-ribose) synthesis in human skin varies by cell type and condition, with distinct patterns in psoriatic, cancerous, and normal tissues.

This study found that a bulge stem cell-enriched population from canine hair follicles successfully formed interfollicular epidermis in vitro within two weeks, suggesting potential for regenerative canine skin therapies.

This case report describes a severe form of HIV-associated pityriasis rubra pilaris in a dark-skinned woman that improved rapidly and sustainably with combination antiretroviral therapy, despite atypical presentation without significant erythroderma.

The researchers reported that the antipsoriatic compounds 1,25-dihydroxy-vitamin D3 and calcipotriol thinned the living cell compartment in organotypic ORS cultures by accelerating the differentiation pathway rather than affecting proliferation.

This study reported that in a histopathologic analysis of five parenteral heroin users with candida folliculitis, candida and pseudohyphae were frequently found in association with hair follicles.

This study explains how the development of keratin-associated proteins in embryonic epidermis is crucial for forming protective barriers in vertebrates, enabling them to adapt to terrestrial environments.

This study established consensus guidelines for diagnosing and managing androgenetic alopecia in Egypt, emphasizing individualized care and emerging therapies based on a survey of Egyptian dermatologists and refinement through expert review.

This article reviews the identification and characterization of soluble proteins in horny tissues such as calluses and psoriatic scales, but reports no new clinical results.

This study found that sub-100 nm size solid lipid nanoparticles showed the most effective skin penetration and depth, mainly via hair follicles, in rat skin.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This study developed a novel regenerative platform using nanozyme-enabled materials combined with exosomes and laser stimulation to enhance wound healing in a mouse model, which more effectively regulated reactive oxygen species and improved early angiogenesis and collagen organization compared to conventional methods.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This study found that 1550-nm Er:Glass fractional laser treatment significantly increased hair density and shaft diameter in patients with androgenetic alopecia, though the mechanism may not involve Wnt10A or IGF-1 expression.

This study quantifies the follicular uptake of tea tree oil in bovine udder skin, with microemulsion showing the highest concentration among different formulations tested.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This study found no evidence supporting the hypothesis that Aβ afferents sprout into the superficial laminas of the spinal cord after nerve injury in rats.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.
