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

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This study found that platelet-rich plasma significantly increased hair density and anagen hair proportions in androgenetic alopecia patients, suggesting potential as an adjuvant therapy.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This study found that oral administration of finasteride to pregnant rats caused dosage-related developmental toxicities, including hypospadias and decreased anogenital distance in male offspring.

This study found that the methanol extract of Eclipta alba showed dose-dependent hair growth promoting activity in pigmented C57/BL6 mice by influencing the transition from the telogen to anagen phase.

This review examines the pharmacological evidence and bioactive compounds in Hibiscus plants, supporting their potential importance for developing treatments for chronic and degenerative diseases, though more research is needed.

This review discusses the use of platelet-rich plasma in various dermatological applications and reports no new clinical results; the authors call for more rigorous trials to confirm its effectiveness.

This article discusses the high toxicity and potential use of thallium as a poison, highlighted by two cases of intentional thallium poisoning.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This review discusses various treatment options for adult female acne, highlighting the need for tailored approaches due to individual patient needs and reports no clinical outcomes.

In this study, PRP injections increased hair count and reduced hair loss in patients with androgenic alopecia not responding to minoxidil and finasteride, with high patient satisfaction reported.

This review discusses the cosmetic applications of platelet-rich plasma in dermatology, highlighting its potential benefits and the need for more controlled studies.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.

This study found that about 80% of known fullerene-binding proteins rank in the top 10% of scorers for C60 docking sites, confirming the accuracy of the predictive model used.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This article reviews the challenges of fasting and dietary regimens in producing sustained weight loss and reports no new research findings or results.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This study reported that 4D-printed, aliphatic polycarbonate-based scaffolds supported adipose tissue engineering by allowing adipocyte infiltration and neovascularization in vivo, indicating potential for effective adipose tissue repair.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This study found that neuroactive steroids like DHEA and pregnenolone influence cocaine-induced appetence in mice through their interaction with the ς₁ receptor, suggesting a role in individual vulnerability to addiction.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.
