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

This study explores the potential connection between circulating cytokines and immune skin diseases, offering insights that may enhance understanding of their causes, diagnosis, and treatment approaches.

This review examines testosterone's role in male health and aging but reports no new clinical results; the authors highlight the need for further research on optimal testosterone levels to prevent age-related conditions.

This review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This review explores the impact of synthetic and herbal drugs on hormone levels and ovarian tissue in PCOD but reports no new clinical findings.

This study found that late embryonic skin injuries can regenerate multiple tissue types, but this ability is hindered postnatally due to fibroblast-driven hyperinnervation, which can be mitigated to enable regeneration.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

In this review, it is discussed how mesenchymal stem cell aggregation plays a crucial role in organ development and has potential applications in organ regeneration through tissue engineering.

This review discusses the role of PIN-FORMED 2 and related signaling pathways in root hair growth regulation and reports no new experimental findings.

This review covers cell transplantation methods for genitourinary reconstruction, discussing tissue sources and complications but presenting no new clinical findings.

This study found that dietary serine levels influence hair follicle stem cells' ability to balance hair regeneration and wound repair, offering insights for potential interventions to accelerate wound healing.

This study found that prevascularizing dermal matrices with adipose tissue-derived microvascular fragments improved vascularization and allowed earlier successful skin grafting in a bradythrophic wound model.

This review discusses the link between metabolic syndrome and various inflammatory skin diseases and reports no new clinical results, emphasizing the importance of recognizing skin manifestations as early indicators of systemic metabolic disorders.

This study found no significant link between iron metabolism, including serum ferritin and hemoglobin levels, and telogen effluvium in women under 40 years old.

This study suggests that finasteride at doses of 5 mg/kg BW or higher may adversely affect spermatogenesis and male fertility in NMRI mice.

This review discusses the role of steroid sulfatase in steroid hormone metabolism and highlights the need for more research on its expression and regulation, especially regarding hormone-dependent tumors.

This paper reviews the complex pathophysiology of polycystic ovary syndrome, exploring how hormonal and metabolic disturbances contribute to its symptoms and related health risks, but it presents no new findings.

This review discusses the skin manifestations of endocrine diseases and reports no new clinical findings, emphasizing the importance of recognizing these signs for early diagnosis.

This review discusses the relationship between obesity and PCOS, highlighting the potential of weight loss and improved insulin sensitivity to alleviate associated symptoms, and suggests the exploration of new therapies targeting weight management.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

Inhibiting PGD2 and using dermal papilla cells may improve skin and hair regeneration.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review summarizes recent findings on how Wnt signaling proteins play crucial roles in the cutaneous wound healing process but reports no new clinical results.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This study describes a 17-year-old male with Klinefelter syndrome who developed androgenetic alopecia and showed a good response to treatment with oral minoxidil, finasteride, and low-level light therapy.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that patterned hair plucking in mice triggers a collective regeneration response in nearby unplucked hair follicles via a quorum sensing mechanism involving immune signaling.

This study suggests that androgen receptor gene CAG repeat length may influence serum free testosterone levels in some PCOS patients, with longer repeats associated with higher testosterone concentrations.

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.
