This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

This study explores autoimmune associations in pediatric patients with alopecia areata at a tertiary care center but reports no new clinical findings.

This study reported a 15% prevalence of tinea capitis among primary school children in Hyderabad, with various dermatophyte species identified as causative agents.

This abstract discusses the effects of finasteride on semen and hormone parameters in men with infertility but does not provide new research findings.

This study found that NB-002, a novel topical antifungal, showed significant antifungal activity and clinically meaningful nail clearing in patients with mild to moderate distal subungual onychomycosis.

This study suggests that Lrig1-positive cells form a previously unknown reservoir of interfollicular epidermal stem cells in adult mouse skin, influencing epidermal proliferation and hair follicle development.

This study found that patterned hair plucking in mice triggers a collective regeneration response in nearby unplucked hair follicles via a quorum sensing mechanism involving immune signaling.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that the prevalence of polycystic ovary syndrome was 16.6% with Rotterdam criteria but decreased to 6.3% or 8.5% when using alternative criteria involving antral follicle count or anti-Müllerian hormone.

This review discusses how overlapping risk factors in women with polycystic ovary syndrome may heighten their risk for severe COVID-19, advocating for integrated care approaches but provides no new clinical results.

This study found that women with polycystic ovary syndrome have an increased risk of developing depressive disorder, anxiety disorder, and sleep disorder compared to those without the syndrome.

This review examines skin symptoms, diagnosis, and treatment of zinc deficiency in children, proposing a classification system but reporting no new clinical results.

This study found that Hopx labels a long-lived progenitor population in hair follicles, which contributes to hair follicle stem cell homeostasis and has an alternative origin from previously thought progenitors.

This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This study mapped genomic copy number variation in Chinese fine-wool sheep, identifying genes involved in sensory perception, nutrient metabolism, growth, and development, and highlighting significant selection on the RXFP2 gene.

In this study, the researchers found that treatment with the JAK inhibitor tofacitinib in alopecia areata patients may reduce clonal CD8+ T cell expansions but does not eliminate them entirely, which could contribute to disease relapse.

In this study, researchers identified and examined males with 17 beta-HSD3 deficiency in a highly inbred Arab population, noting genetic findings and the progression of male characteristics despite being raised as females initially.

This study found that an SNP in the FGFR2 gene, rs4752566, was significantly associated with hair thickness in Asian populations, suggesting an effect on hair morphology through altered FGFR2 expression levels.

In this study, PCOS was the most common cause of hirsutism among Turkish women, but about 17% had idiopathic hyperandrogenemia with no clear cause identified.

This study found that Ng2+ perivascular cells in mouse skin are a diverse lineage-restricted population primarily recruited from papillary or reticular fibroblast lineages during wound healing, maintaining heterogeneity in both wounded and non-wounded skin.

Older adults commonly experience wrinkles, itchy skin, psoriasis, fungal infections, skin growths, grey hair, hair loss, and nail ridging, but no skin cancer was found in this group.

This study found that individuals with AA have a higher incidence of atopic and autoimmune conditions, suggesting both Th1 and Th2 immune responses may play a role in its development.

This study reports that X chromosomes often show greater differentiation between human populations than autosomes, likely due to a mix of demography and selection pressures.

The study observed that Americans of Hispanic descent have a statistically significant higher hair density than individuals of African descent but lower than Caucasians, which may assist in diagnosing and researching hair disorders.

This study found that the reproductive function of female hairdressers may be negatively affected by long-term exposure to permanent-waving solutions containing thioglycolic acid, raising concerns about its potential carcinogenic effects.

This study found that higher prenatal and early childhood lead exposure may be associated with delayed pubertal development in girls, but not in boys, in Mexico City.

This study found that early-onset male pattern baldness was associated with a reduced relative risk of prostate cancer.

This study found a notably high prevalence of metabolic syndrome among apparently healthy individuals in Pakistan, with high triglycerides, low HDL, and central obesity identified as significant risk factors.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.
