This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This review discusses phytotherapy options for managing benign prostatic hyperplasia, noting some herbal agents show promise in trials for mild-moderate symptoms but more evidence is needed for others.

In this study, researchers found that electrospun membranes with aligned surface topography advanced the immune response towards an adaptive stage and highlighted the role of T cells in hair follicle regeneration in mice, showcasing the intricate interactions between immune and skin cells.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This article discusses Kennedy's disease, detailing its genetic cause, symptoms, and diagnostic criteria, but reports no new clinical findings and highlights a lack of causal therapy.

This review outlines the development, applications, and challenges of microneedle-based drug delivery from 2000-2019, particularly highlighting fabrication techniques, but reports no new clinical results.

This review discusses the role of lamins in development, tissue maintenance, and stress response, and does not report new experimental findings.

This study suggests that finasteride may reduce the aggressiveness and invasion of prostate tumors, with effects potentially differing based on the androgen responsiveness of the patient's prostate cells.

This review summarizes the recent advances in molecular mechanisms influencing tissue sensitivity to glucocorticoids, emphasizing novel mutations and new information on the glucocorticoid receptor's circadian rhythm and ligand-induced repression, but reports no new results.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This review discusses the role of peroxisome proliferator-activated receptors and their agonists in dermatology but reports no new clinical results.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study found that disrupting inflammasome signaling by eliminating caspase-1 and -11 in mice reduced skin inflammation and delayed the onset of disease, highlighting their role in skin disease pathogenesis.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

This study observed that in hormone-starved prostate cancer cells, the androgen 5alpha-dihydrotestosterone rapidly induces matriptase activation and shedding, which involves androgen receptor signaling and requires both transcription and protein synthesis.

This study found that FOXN1 haploinsufficiency is a significant genetic factor causing T cell lymphopenia at birth, linked to reduced thymic function in both humans and mice.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

This study suggests that activating retinoic acid signalling can inhibit Wnt signalling and induce regression in certain skin tumors, providing potential therapeutic strategies for tumor regression.

This study found that MRL/MpJ mouse dorsal skin wounds heal with similar scar formation and collagen deposition as C57bl/6 and Balb/c mice.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This review discusses the potential therapeutic effects of targeting the endocannabinoid system for chemotherapy-induced peripheral neuropathy and reports no new clinical results, highlighting the need for ongoing research.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.

This review discusses the development and selectivity of 5 alpha-reductase inhibitors, particularly non-steroidal ones, and reports no new clinical trial results.

This review summarizes the application of microneedles in treating various skin diseases and highlights challenges like low drug loading, noting no new clinical results are reported.
