This study examined variations in epidermal thickness and protein expression across different dog breeds, finding significant differences by anatomical site and breed, with associated mRNA and protein expression changes observed.

This study identified a new subtype of lichen planopilaris that mimics androgenetic alopecia, selectively affecting vellus hair follicles and presenting unique histopathological features.

This report documents the first known case of cutaneous mastocytosis associated with congenital alopecia areata in a young Korean girl, confirmed through histopathological examination.

This study found that combining second-harmonic generation with optical coherence tomography may effectively evaluate wound healing by monitoring collagen formation and optical signal changes in regenerated tissue.

This study provides a comprehensive analysis of anabolic-androgenic steroids, reporting that their use enhances muscle mass but is associated with significant health issues including cardiac muscle hypertrophy, liver disease, and changes in gender characteristics, emphasizing the need for patient awareness of these risks.

This study found that ursolic acid at 50 mg/kg improved biochemical, hormonal, and ovarian histopathological markers in a rat model of PCOS, suggesting its potential as a therapeutic option.

This case report highlights the importance of considering trichofolliculoma in the differential diagnosis of scalp lesions, with histopathological examination essential for accurate diagnosis.

In this randomized, placebo-controlled study, Kūlaris supplementation significantly improved quality of life for participants with mild-to-severe acne over 12 weeks, though no significant changes in general skin health measures were observed compared to placebo.

This case report describes a middle-aged man with chronic tophaceous gout who experienced a rare form of non-scarring alopecia due to urate crystal deposition around hair follicles, leading to hair loss that remarkably improved with targeted treatment including allopurinol and lifestyle changes.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

In this study, researchers observed that administering the minimum dose of levothyroxine to a hypothyroid Dalmatian effectively restored normal skin condition and hormonal levels, suggesting levothyroxine's potential effectiveness in managing skin changes caused by hypothyroidism in dogs.

This study found that activation of the transcription factor Nrf2 in keratinocytes promotes wound healing in mice by expanding hair follicle stem cells, independent of changes in keratinocyte proliferation or migration.

This study observed that 21.6% of oncology patients experienced dermatological side effects from anti-cancer drugs, with hair loss and skin pigmentation changes being the most common.

This study reported that heterozygosity for FHIT affects mice's susceptibility to spontaneous alopecia areata and to certain preneoplastic lesions induced by benzo[a]pyrene, but does not change how they respond to budesonide and N-acetyl-L-cysteine.

This case report highlights traction alopecia in two adolescent Sikh brothers who developed scarring alopecia from wearing a turban, emphasizing the importance of early changes in hair care to prevent irreversible hair loss.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.

This study suggests that the use of 5α-reductase inhibitors in men may be associated with macular abnormalities, characterized by cystoid changes and foveal cavitation, potentially progressing to more severe defects.

This study discusses incidental findings of syringomas and syringomatous proliferations in areas of scalp alopecia, suggesting they may be secondary to reactive changes from subclinical alopecia.

This review discusses primary cicatricial alopecias, detailing their classification, pathogenesis, clinical features, histopathologic findings, and treatment, without reporting new experimental results.

This study reported that diffuse lichen planopilaris significantly impairs quality of life in Moroccan patients, with trichodynia and hair quality changes most affecting daily functioning and leisure activities.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This study found that while the macular, retinal nerve fiber layer, and retinal layers' thickness were similar between alopecia areata patients and controls, the choroidal thickness was significantly thicker in the alopecia areata group, suggesting potential inflammation-related changes.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

This pilot study found that examining changes in scalp scales after scraping may effectively distinguish seborrheic dermatitis associated with androgenetic alopecia from fibrosing alopecia in a pattern distribution.

This review discusses the changes in hair follicles with aging, particularly graying due to decreased melanocyte activity, and suggests potential for hair repigmentation under certain conditions, but reports no new results.

This study found that administering dutasteride did not change spermatogenesis or oxidative stress levels in rat testes, though further research is needed to confirm these findings.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This study identifies various nail changes in alopecia areata, which can affect quality of life, and suggests that while spontaneous improvement is possible, further research is needed to refine treatment strategies.
