This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study observed that among a cohort of reproductive-aged women in the U.S., the prevalence of PCOS was about 4.0%, with no significant racial differences between White and Black women.

This review discusses the expression patterns and biochemical roles of Msx and Dlx genes during development but does not present new research findings.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

In this study, patients with seasonal affective disorder were found to have increased functional connectivity in certain brain networks and higher low-frequency fluctuations compared to healthy controls, which aligns with their attentional and psychomotor symptoms.

This study suggests that stress may worsen Tourette syndrome symptoms in mice by increasing allopregnanolone synthesis, with findings supporting finasteride as a potential treatment to manage symptom fluctuations.

This study found that inhibiting the enzyme 5α-reductase with finasteride counteracted stress-induced prepulse inhibition deficits in socially isolated rats by altering neuroactive steroid concentrations in the brain.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study suggests that synthetic steroid analogues or 5α-reductase modulation could be potential therapeutic strategies for nervous system disorders, but further research on their effects is necessary.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This article describes a case of oral pigmentation that posed a diagnostic challenge in determining Addison’s disease and includes a brief review, reporting no new clinical results.

The study found that exogenous decorin administration accelerated the anagen phase and delayed the catagen transition, suggesting it may act as a positive regulator of the hair cycle.

This study found that the Plcd3(mNab) mutation in mice worsens the alopecia caused by Plcd1 loss, suggesting synergistic effects between Plcd1 and Plcd3 on hair follicle health.

This study found that in C57BL/6 mice, treatment with fermented red ginseng marc, a traditional polyherb formula, or a combination of both, promoted hair growth by enhancing the hair-growth cycle.

The document concludes that early diagnosis of Balint's syndrome is crucial for effective treatment and that understanding drug interactions, like between ritonavir and statins, is important for patient care.

Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.

This study introduces PROMETHEUS, a framework that organizes causal claims from scientific texts into navigable and persistent "causal atlases," enhancing research by highlighting localized evidence, agreement, and contradictions within complex data sets.

In this study, lower dihydrotestosterone and higher testosterone levels were linked to increased brain activation during response inhibition, although no behavioral changes were detected.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

This study developed a method to measure local steroid hormone concentrations in hair, providing new insights into hormone dynamics associated with androgenetic alopecia.

This article explores how natural and man-made factors shape architecture and environments for human activity in emergency situations, focusing on the unique conditions of the Republic of Kazakhstan. Results are not reported.

In this study, treatments using a shampoo and conditioner with hematin helped repair damaged hair by depositing a cuticle-like structure, straightening hair as observed through electron microscopy.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

This article discusses the widespread issue of zinc deficiency affecting plant, animal, and human health, and reports no new clinical results; the authors emphasize the need for adequate zinc availability in agriculture and nutrition.
