In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

This study observed that basal cell carcinomas with matrical differentiation may derive from hair follicles, with .-catenin potentially playing a key role in tumor development and differentiation.

This case report documents unilateral madarosis and facial alopecia as potential adverse effects of botulinum A toxin injections in a patient treated for left oromandibular dystonia.

This study reports that the prevalence of male pattern baldness in Asians is higher than previously believed, with potential links to socioeconomic factors and westernized diets, though the exact cause remains unclear.

This study reported that topical 2% minoxidil solution improved hair growth compared to placebo in men with early male-pattern baldness over 24 weeks, with no significant safety issues observed.

This review focuses on the various skin symptoms associated with COVID-19 but reports no new clinical findings.

This study found that zip codes in Oakland County, MI with larger Black populations were disproportionately affected by COVID-19, experiencing higher incidence rates, though racial composition was not linked to case fatality.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

This study found that the PSEN1-P242LfsX11 mutation in hidradenitis suppurativa influences cytokine and chemokine expression in macrophages, potentially affecting inflammatory responses.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study suggests that the androgen receptor locus on the X chromosome may play a role in the pathogenesis of early-onset female pattern hair loss.

This review examines the roles of Hedgehog and Gli proteins in mouse embryonic mammary development and suggests that Gli3-repressor-mediated off-state of Hedgehog signaling determines mammary fate over hair follicle fate.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

In this study, 53% of patients with male pattern baldness experienced significant hair growth with one year of topical minoxidil, while 95% rated its effectiveness as moderate or excellent.

This study found that the HoxC gene cluster plays a critical role in the development of ectodermal organs, including hair and nails, with mammalian-specific enhancers increasing transcription levels during development.

This study found that combining fractional radiofrequency microneedling with 5% topical minoxidil improved hair count and thickness more than minoxidil alone in Chinese men with male pattern hair loss.

This study found that scalp cooling effectively reduces chemotherapy-induced hair loss, especially with taxane-based regimens, and recent U.S. trials support its safety, despite logistical and insurance challenges.

This review discusses common hair and nail diseases in the elderly and reports no new clinical results, noting their significant impact on quality of life.

This study found that a marine complex supplement significantly reduced hair shedding and increased hair growth in men with thinning hair over 180 days.

This study found that finasteride decreases DHT/T levels more significantly in the vertex scalp hair than in the occipital hair of patients with male pattern baldness.

This study found that skin diseases, particularly foot problems, are prevalent among male boarding school students, with many students unaware of their condition or not seeking medical help.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

This study found that using a dissecting microscope for follicular unit graft preparation in hair transplant surgeries increased hair yield by 17% compared to using magnifying loupes with transillumination.

Male pattern hair loss negatively affects quality of life, but drug treatments can help.

This review discusses the pharmacological actions of mangiferin and the potential of delivery carriers to overcome its limitations, but reports no new clinical results.

This study found that quaternary ammonium iminofullerenes (IFQA) can alleviate oxidative stress in maize caused by hydrogen peroxide, promoting root growth by enhancing antioxidant cycles and reducing ROS accumulation.

This review discusses the roles of various PLA2 enzymes in skin health and disease, highlighting potential pathways for future diagnosis and therapy, but it reports no new clinical results.

In this study, micro-autologous fat transplantation (MAFT) for frontal augmentation using the MAFT-GUN showed high patient satisfaction and no complications among 178 patients, suggesting it may be a reliable method for forehead contouring.
