This review explores possible reasons for why male COVID-19 patients experience more severe symptoms and higher fatality rates than female patients but provides no new clinical results.

This review discusses the roles of Eph receptors and ephrins in various diseases, highlighting their potential as therapeutic targets, but it presents no new research findings.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

Keratins are crucial for cell structure, growth, and disease risk.

This review discusses the use of antiandrogens like flutamide and its derivatives in prostate cancer treatment and highlights the need for next-generation antiandrogens for improved efficacy; it reports no new clinical results.

The cuneate nucleus has two main neuron types: relay neurons and interneurons.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but reports no new clinical results.

This article discusses the long-standing use and safety of opioids in anaesthesia, noting that respiratory depression is a manageable side effect due to the availability of opioid antagonists.

This article discusses advancements in understanding how skin stem cells and fibroblasts contribute to scar formation, highlighting current and potential therapies aimed at preventing or reducing scarring, yet notes that effective treatments without significant side effects are still lacking.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This study suggests that stress negatively affects hair growth by inducing inflammation and early hair cycle transitions in mice, which might inform strategies for managing stress-related hair loss in humans.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This study found that DrugNet, a network-based prioritization method, effectively improves drug repositioning tasks, achieving high performance in validation tests and clinical trial comparisons.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

In a neonatal rat model, this study found that topical CDK2 inhibitors reduced chemotherapy-induced hair loss in 33 to 50% of the animals, suggesting a potential strategy for preventing alopecia in cancer patients.

This review discusses recent advances in understanding gender differences in skin and their implications for dermatologic diseases, but it reports no new experimental results; ongoing research is necessary for translating these insights into clinical practice.

This review discusses the pathogenesis, clinical presentation, diagnosis, and treatment of cutaneous lupus erythematosus, reporting no new clinical findings.

This review discusses the WNT signaling pathway's involvement in human diseases and highlights recent advances in WNT-related treatments, but it presents no new research findings.

In this study, patients with generalized pustular psoriasis were classified into subgroups to better understand the disease's variability and assist in treatment selection, highlighting the role of localized infections in triggering flares.

This review discusses the molecular mechanisms by which oncogenic viruses contribute to cancer development through manipulation of host cellular functions and highlights the need for further research into virus-associated cancers, reporting no new results.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.
