This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

This study reports that the mouse Scube3 gene is expressed in various tissues during embryonic development, including the neural tube, limb buds, developing tooth, hair follicle, and skeletal regions.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

In this study, miR-324-3p was found to promote differentiation and migration in cultured keratinocytes and is highlighted as a potential target for treating androgenic alopecia.

This study found that using the OptoTrkA system to control TrkA activity with blue light enhanced proliferation, migration, and differentiation of hair-follicle-derived stem cells into neuronal and glial cells.

This review discusses the diagnosis and management of severe cutaneous adverse reactions to drugs and provides guidance for physicians to improve patient outcomes, but it reports no new clinical results.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This article reviews recent advancements in understanding and treating androgenetic alopecia, focusing on new genetic insights, stem cell roles, and diagnostic tools, without reporting new clinical results.

This review discusses the classifications, diagnostic methods, and treatment strategies for female pattern hair loss, but reports no clinical results.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This analysis suggests that platelet-rich plasma therapy may be promising for treating androgenetic alopecia, but further controlled trials with standardized measures are needed to confirm its efficacy.

This article provides an overview of diagnosing Cushing's syndrome, emphasizing the importance of assessing clinical signs and the appropriate use of first-line biochemical screening.

In this study, transgenic male mice over-expressing the androgen receptor in mesenchymal stem cells showed reduced fat mass and improved glucose clearance, suggesting enhanced androgen sensitivity may alter body composition.

This review examines the debated link between iron deficiency and nonscarring scalp alopecia in women, offering no new clinical results but emphasizing the need for further research and well-designed trials.

This study found that testosterone and dihydrotestosterone are crucial for synaptic transmission and spine density in male hippocampal neurons, suggesting sex-specific effects of neurosteroids on brain development.

This article reviews existing knowledge on postmenopausal hyperandrogenism and highlights diagnostic challenges, reporting no new clinical results.

This study identified Activin A and follistatin as key regulators of hair cell differentiation in the mammalian auditory sensory epithelium, with Activin A signaling influencing the timing and pattern of cell differentiation.

This review discusses the diagnostic challenges of androgen and estrogen-secreting adrenal tumors and highlights that the presence of metastases is the most reliable indicator of malignancy; it reports no new clinical findings.
