This study demonstrates that bioengineered tooth germ autologously transplanted in a postnatal canine model can achieve functional tooth restoration, suggesting its potential for future clinical regenerative medicine.

This review discusses current and emerging drug therapies for treating androgenetic alopecia and alopecia areata, and reports no clinical results; it highlights a need for improved and novel treatments.

This article discusses the complexities of diagnosing and managing polycystic ovary syndrome in adolescents and highlights the lack of established diagnostic criteria and unclear clinical implications, without presenting new clinical findings.

This review highlights the unique scarless wound healing abilities of fetuses and discusses potential applications to adult wound healing, reporting no new experimental findings.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This review highlights the potential of near-infrared light therapy to improve metabolic, antioxidant, and cognitive functions without adverse effects, and supports its use for visual and neurological conditions through molecular and cellular mechanisms, as reported in this source.

This review examines the definition, etiology, pathogenesis, and clinical features of polycystic ovary syndrome but reports no new clinical findings.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.

This study found that 62% of neutered dogs with hair cycle arrest experienced partial to complete hair re-growth after melatonin treatment, but hair re-growth was not consistently linked to normal sex hormone levels.

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 enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

In this study, artesunate was confirmed as an effective treatment for severe malaria, but post-treatment hemolytic anemia occurred, although it was mostly mild and only one transfusion was needed.

This study found that combining cyproterone acetate with testosterone enanthate was highly effective in suppressing spermatogenesis, suggesting potential as a reversible male contraceptive method.

The study found that melatonin treatment in early postnatal cashmere goats increased both the quantity and quality of cashmere by promoting secondary hair follicle development and enhancing antioxidant enzyme activities.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This article discusses the complexities of androgen and antiandrogen therapies in women, detailing diagnostic measures, the effects on libido, and the potential benefits of new progestins with antiandrogenic properties, but presents no new empirical findings.

This article outlines management guidelines for androgenetic alopecia, highlighting that continued treatment with medications like finasteride or minoxidil typically halts progression and improves hair condition in most mild to moderate cases.

This review discusses the potential of repeated low-level red-light therapy to inhibit myopia progression through metabolic effects, highlighting its molecular and cellular impact, but reports no new clinical results.

This study supports evaluating metabolic syndrome and insulin resistance in young males with advanced androgenic alopecia to potentially reduce future cardiovascular and type 2 diabetes risks.

In this study, the combination of finasteride and minoxidil significantly increased hair growth in balding male stumptail macaques compared to each drug alone.

This study reported that in rat retinas under high pressure, allopregnanolone synthesis increased and helped reduce pressure-induced damage through GABAA receptors, suggesting potential therapeutic use in glaucoma.

In this study, men with AGA who took finasteride 5 mg daily for 24 months showed a significant increase in hair counts compared to those who received a placebo.

In this uncontrolled study, ivermectin treatment for scabies resulted in the resolution of symptoms and negative skin scrapings in most patients at follow-ups.

This study found that in vitro treatments with 5alpha-reductase inhibitors and androgen receptor antagonists strongly stimulate VEGF expression in dermal papilla cells.
