This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study found that specific dermoscopic signs, such as diameter diversity of leukotrichia and Pohl-Pinkus constrictions, were associated with progressive vitiligo, and early-stage melanin synthesis was impaired in vitiligo-associated leukotrichia.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

In this small study, topical minoxidil 2% was associated with an increase in normal hair shaft production in patients with Monilethrix without any reported side effects.

Ichthyoses are genetic skin disorders that affect the skin's barrier function.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

This study found a previously unreported ST14 gene mutation in a patient with ichthyosis-hypotrichosis syndrome, highlighting novel skin and hair characteristics and emphasizing the critical role of the Asp482 amino acid in matriptase activation.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

This study describes a modified reduction-osmication method for staining human scalp hair that improves reagent penetration and visualization of hair cortex features using transmission electron microscopy.

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 the effectiveness of scalp cooling in preventing chemotherapy-induced alopecia in early-stage breast cancer patients depends on the integrity of the follicular pigmentary unit, particularly consistent melanosome quantity.

This study found that two unrelated domestic shorthair cats had novel DSG4 gene mutations causing defective hair shafts, representing the first report of pathogenic DSG4 variants in domestic animals.

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 in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

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.

This review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This article discusses recent findings on piedra infections in hair and their keratinolytic activities, but reports no new clinical results.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This study investigated the histopathology of ectodermal dysplasia/skin fragility syndrome, identifying specific skin and hair abnormalities associated with PKP1 gene mutations in two young female patients.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.
