This study determined that an mFG score of 5 or greater defines hirsutism among Southern Chinese women, with prevalence and score thresholds decreasing with age.

This study found that hyperandrogenemia in Chinese women with PCOS is associated with higher risks of type 2 diabetes and obesity, suggesting it should be prioritized in managing PCOS-related infertility.

This study found that PlncRNA‑1 may enhance the proliferation and differentiation of hair follicle stem cells by upregulating the TGF‑β1-mediated Wnt/β-catenin signaling pathway.

This study determined that the upper normal cut-off levels for free testosterone, dehydroepiandrosterone sulfate, and total testosterone among reproductive-age women in China are 26 pmol/L, 4.92 μmol/L, and 2.39 nmol/L, respectively.

This study found that engineered skin substitutes made with skin-derived precursors and epidermal stem cells can regenerate hair follicles after grafting into nude mice.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study observed that consuming 50g of cheonggukjang daily for 3 months improved eyebrow length, thickness, and reduced damage in middle-aged women compared to controls, although the number of eyebrows did not change.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study found that a specific amino-pyridine compound showed potent androgen receptor antagonist activity, stimulating hair growth in mice and reducing sebum production in a hamster model.

This study observed that deleting PTEN in mouse facial motoneurons enhanced peripheral axon regeneration but also led to physiological changes and potential hyperplasia in older mice.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

Drinking alcohol 1-2 times a week may reduce urinary symptoms, but drinking more often might increase the risk.

In this study, researchers observed that heat stress significantly affected hair and skin traits in two indigenous goat breeds, with Kodi Aadu goats demonstrating greater thermal resilience compared to Kanni Aadu goats, potentially due to differences in gene expression and methylation.

EGFR signaling is essential for ear cell regeneration in both birds and mammals.

This study found that multipotent, nestin-expressing stem cells from the upper part of hair follicles can proliferate significantly and differentiate into various cell types, showing potential for nerve and spinal cord repair.

This review discusses the potential of using triads of repositioned medicines targeting multiple pathogenic mechanisms to prevent or delay retina degeneration, but reports no new results.

This study reviews progress in understanding how redesigned lipid metabolism supports energy production and treatment resistance in advanced carcinomas, highlighting a hypothesis supported by preclinical and clinical evidence and suggesting potential clinical targeting of resistance mechanisms.

This study found that boys in Mexico City with selenium intake below the recommended dietary allowance had lower odds of progressing to advanced stages of pubertal development, while no association was observed in girls.

This study reviews current treatments for PCOS and evaluates Tirzepatide as a potential option for its management, suggesting possible benefits for those with obesity and metabolic syndrome but not for those of normal weight.

This review outlines key considerations for designing fluorescence microscopy experiments in cell biology, discussing the importance of hardware availability, suitability of biological models, and imaging agents to achieve high-resolution and informative images.

This study highlights emerging research on lactate's biological roles in skin health, emphasizing its function as a signaling molecule that regulates skin barrier and immunity, and notes its therapeutic potential for skin conditions such as tumors and inflammatory diseases.

This study found that an aqueous extract of Bacopa procumbens improved motor function and preserved neuronal structure in a mouse model of Parkinson's disease, suggesting its neuroprotective potential.

This study reports that sebaceous glands can regenerate after injury through stem cell plasticity, with hair-follicle-derived stem cells replacing sebaceous gland progenitors and playing a crucial role in the regeneration process, which is dependent on FGFR2 signaling and aided by hair growth induction.

This review highlights the use of natural products in cosmetic-containing herbals for skin and hair care but reports no new clinical results, calling attention to their claimed curative properties and minimal side effects.

This study found that CXCL12+ fibroblast subsets in mouse skin play a critical role in recruiting neutrophils and defending against S. aureus infection, with similar fibroblast activity observed in human psoriatic skin.

This review discusses the host genetic factors influencing COVID-19 susceptibility and pathogenesis, highlighting genetic variations that affect viral entry and immune responses, but reports no new experimental results.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This study found that Prdm1 is crucial for whisker development in mice, affecting multiple signaling pathways and possibly playing a role in primates' evolutionary loss of vibrissae.
