This review explores whether SARS-CoV-2 could trigger or worsen α-synucleinopathies, like Parkinson's disease, by affecting α-synuclein misfolding and aggregation, potentially linking COVID-19 with the development of parkinsonism-like symptoms.

This chapter reviews recent developments in vitiligo research, highlighting the role of melanocyte stem cell differentiation and oxidative stress in its management, but reports no new clinical results.

This study observed that among male patients who experienced telogen effluvium after platelet-rich plasma treatment for androgenic alopecia, there were elevated levels of TNF-α, androgen receptors, and altered 5α-reductase gene expression, suggesting these factors as potential contributors to this unintended outcome.

This study found that IL-4 VNTR intron 3 and TNF-α (rs1799964) gene polymorphisms do not have a significant association with alopecia areata susceptibility in the Egyptian population.

This review discusses common skin eruptions caused by biologics in treating inflammatory bowel disease and proposes tailored therapeutic approaches for managing these adverse reactions.

This review discusses how dehydroepiandrosterone (DHEA) may exert its biological effects through multiple receptors and reports no new clinical results.

This study explored the effects of MOTILIPERM on infertility in a rat model with varicocele and oxidative stress, reporting its potential therapeutic efficacy.

This study identifies specific localization patterns of androgen, estrogen, and progesterone receptors in human skin, which could be crucial for understanding their roles in skin biology and pathology.

This study found that both declining levels of the neurosteroid THP and increasing levels of estradiol before puberty trigger maximal expression of α4βδ GABAA receptors in the CA1 hippocampus of female mice.

This study found that Ageratum conyzoides extract enhanced hair growth in mice and human follicle cells, showing potential for hormonal modulation, pathway activation, and antioxidant protection; however, further clinical studies are needed to confirm efficacy in humans.

This study found that in vitro, EGCG may help treat colorectal cancer by targeting iron chelation and the ER stress pathway, leading to apoptosis in cancer cells while sparing normal cells.

This study found that hair shaft miniaturization in aging and genetic hypotrichosis leads to hair follicle stem cell loss through mechanical compression and apoptosis mediated by the Piezo1 channel.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

Estrogen receptor α controls hair growth cycles and skin thickness in male mice.

This review discusses potential therapeutic options for frontal fibrosing alopecia by exploring distinct signaling pathways and cellular players, but reports no new clinical findings and emphasizes the need for further trials.

This review discusses the effects of hormonal changes on hair follicles, concluding that hormones like androgens and estradiol significantly influence hair growth and cycle, while the roles of other hormones are still being researched.

This review discusses the production, role, and measurement of dihydrotestosterone (DHT) in various disorders of sexual development but does not report new clinical results.

This study reports that TFM-4AS-1, a selective androgen receptor modulator, promoted bone and muscle growth with reduced effects on reproductive organs in ovariectomized rats.

This study determined that the human steroid 5α-reductase enzymes localize to the endoplasmic reticulum in HeLa cells, with protein tagging affecting expression and inducing protein aggregates for some isoforms.

This review discusses the molecular differences between male and female responses to SARS-CoV-2 infection and highlights the lack of specific guidelines for altering sex-specific COVID-19 prognoses.

This review discusses how aging affects hair follicle stem cells and their environment, contributing to hair loss, and explores strategies to promote hair regrowth, but reports no new results.

This article discusses the teratogenic risks of skin condition treatments for individuals with DSD and notes that testosterone replacement, often used in this population, may cause acne.

This study observed that Kelulut honey effectively normalized the expression of certain sex steroid receptors in PCOS-induced rats, similar to metformin and clomiphene.

This study found that neonatal blocking of androgen and estrogen pathways in rats altered sex-specific expression of estrogen and androgen receptors in adult pituitary and adrenal glands, potentially influencing lifelong neuroendocrine function.

This study found that supercritical fluid extraction of germinated perilla seed significantly promoted hair follicle cell proliferation and gene expression related to hair growth, suggesting its potential as a natural treatment for hair loss.

Alopecia treatments like 5α-reductase inhibitors and spironolactone are safe for breast cancer patients and high-risk women.

This review examines the hormonal causes of hair loss, noting how androgen excess can lead to follicle miniaturization and linking estrogen deficiency and thyroid dysfunction to common alopecia types. It further discusses hormonal treatments such as finasteride, dutasteride, and spironolactone.

This study found that microneedling-induced microinjury in mice promoted hair growth by stimulating the TNF-α/Wnt/VEGF pathway, and blocking TNF-α inhibited this process.

This review discusses the current status of genetic research on male-pattern hair loss and reports no new findings, outlining significant achievements and future challenges in understanding its biology and treatment.

In this rat study, offspring from females fertilized by finasteride-treated males showed hyperglycemia and increased hepatic glycogen, linking paternal androgen imbalance to liver issues across generations.
