In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

This review explains that dysregulated sebum secretion and composition contribute to acne and impaired skin barriers while highlighting factors like diet and hormones affecting sebaceous activity, and identifies novel molecular targets and model systems for future therapeutic developments.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

This study demonstrated that combining AMD3100 with low-dose tacrolimus in a stem cell mobilization approach significantly reduced wound healing time and improved scar and hair follicle regeneration in full-thickness skin wounds.

In this report, a 25-year-old female patient with anti-MDA5 antibody-positive dermatomyositis and alopecia areata achieved complete remission of hair loss after treatment with baricitinib.

This study reports a rare case of follicular porokeratosis in a diabetic woman, suggesting a potential association with diabetes mellitus in addition to its known presentation with keratotic papules and scalp alopecia.

In this study, researchers are constructing a comprehensive data set from 997 adult participants in Japan to develop a statistical model that explores the relationships among various health parameters, aiming to enable personalized and preventive health care interventions based on empirical data.

In this case study, a 12-year-old boy with isolated nail lichen planus showed significant improvement after receiving intramuscular triamcinolone acetonide and topical tacrolimus treatment, although his great toenails were less responsive.

This review discusses the potential benefits of nonantibiotic macrolides for treating inflammatory skin disorders and reports no new clinical results.

This study analyzed research trends in discoid lupus erythematosus, revealing shifting focus areas and highlighted the importance of interdisciplinary collaboration between dermatology and other fields.

This article lists the clinically important interactions and skin reactions of several drugs and substances, including THA, FK506, tamoxifen, tamsulosin, tartrazine, tea tree oil, temazepam, and temozolomide, but provides no new clinical results.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

This review discusses the relationship between gut microbiota and polycystic ovarian syndrome (PCOS), including its potential mechanisms and the role of alterations in microbiome composition on PCOS pathophysiology.

This study found that the DKK3-CKAP4 signaling axis is involved in fibroimmune remodeling in androgenetic alopecia and that targeting this pathway may restore a regenerative hair follicle environment, offering a potential therapeutic strategy to counteract hair follicle miniaturization.

This study suggests that keratin peptide signatures in human hair shafts may potentially be used to distinguish gender and ethnicity, although further validation with larger samples is needed.

This study demonstrated potential in using specific keratin peptide profiles from human hair shafts to distinguish gender and ethnicity, suggesting it could enhance forensic investigations, though larger studies are needed.

Pregnancy can cause skin changes and affect existing skin conditions, with limited treatment options due to the need for fetal safety.

This study used single-cell RNA sequencing to analyze 26,573 cells from the scapular skin of yaks, identifying 11 major cell types and providing insights into the diversity and morphogenesis of hair follicle cell types through detailed maps of DP cells and dermal fibroblasts.

Keratin peptides can change hair shape gently without harsh chemicals.

This study suggests that keratin peptide signatures in human hair shafts could potentially be used to distinguish gender and ethnicity, though further research on a larger scale is needed.

This study found significant changes in gene and protein expression related to hair follicle development in Rex rabbits' skin during the first 8 weeks of life.

In this study, gene expression changes in rat whisker follicles after methamphetamine administration may serve as indicators of the drug's rewarding effects and potential addiction pathways.
