This study observed that elderly women exhibited a tendency for higher personal anxiety and increased brain DC-potential indicators, with distinct energy cost patterns in different brain regions compared to elderly men.

This study identified distinct plasma miRNA profiles in alopecia areata that may aid in diagnosis and therapy, but further validation is needed to confirm these exploratory findings.

This review paper discusses the effectiveness of repurposed drugs and potential novel therapies for treating COVID-19, highlighting remdesivir as the only FDA-approved medication and listing others with Emergency Use Authorization.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

In this study, Caplan et al. found that treatment with human Tregs expanded from umbilical cord blood may modulate immune responses and improve outcomes in a rodent model of traumatic brain injury.

This review discusses the role of biomaterials and colloidal drug delivery systems in promoting tissue regeneration within regenerative medicine, but it reports no new clinical results.

This review discusses the use of platelet-rich fibrin (PRF) in musculoskeletal, oral, and maxillofacial surgeries and dermatology, but reports no new clinical results; further trials are needed.

This review discusses the potential of platelet-rich plasma in regenerative medicine and aging-related diseases but notes that clinical efficacy remains unclear due to varying study results and preparation inconsistencies.

This review reports that chitosan, a versatile polysaccharide, shows potential for various therapeutic applications due to its chemical modifications, notably in treating non-communicable diseases and wound healing, though further clinical study is needed to confirm these benefits.

This review highlights the importance of selecting high-quality bioassays in discovering bioactive compounds from marine sources, emphasizing their role in evaluating safety and efficacy during pharmaceutical, food supplement, and cosmetic development.

This review discusses the use of human-to-mouse xenografting to study human skin processes in vivo, highlighting its importance for understanding skin regeneration and pathology while identifying knowledge gaps and challenges in applying these findings to human skin.

This study found that hormone replacement therapy was associated with reduced COVID-19 mortality and adverse outcomes in nonimmunosuppressed postmenopausal women and immunocompromised male solid organ transplant recipients.

This study found that quercitrin, a natural compound, enhances Wnt/β-catenin signaling and may help mitigate synapse loss and memory impairment in Alzheimer's models.

This study found that both a high dose of CPA and GnRHa are effective for treating hirsutism in hyperandrogenic women, but GnRHa with add-back therapy may lead to a longer remission period.

This study reports that a young man with severe testotoxicosis maintained spontaneous fertility despite suppressed FSH levels, underscoring the importance of high intratesticular testosterone levels for spermatogenesis.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This study found that the GGC repeat length significantly influenced testosterone levels in oral contraceptive users from high-risk breast cancer families, and homozygosity for short alleles may be linked to increased breast cancer risk.

This review discusses the evolution of diagnostic criteria for polycystic ovary syndrome and emphasizes its association with various metabolic and cardiovascular risks, but it provides no new research findings.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

No genetic link between prostaglandins and hair loss found.

This review discusses the role of oestrogens in stimulating growth hormone secretion and influencing linear bone growth in children, and reports no new clinical results; the authors suggest that oestrogens play a key role in pubertal growth spurts for both genders.

This study found that women with polycystic ovary syndrome have a higher prevalence of non-alcoholic fatty liver disease and increased androgen bioavailability may be involved alongside metabolic factors.

This review outlines the challenges in diagnosing hyperandrogenism in women, focusing on its manifestations like hirsutism, acne, and virilization, but provides no new results.

This study reports a method for efficiently synthesizing chromeno-pyrimidine-N-oxides in good to excellent yields, confirmed by X-ray analysis, through a reaction between 4-chloro-3-formylcoumarin and aromatic carboximide oximes.

This study found that spironolactone directly inhibits 5 alpha-reductase activity in hirsute women, resulting in decreased conversion of testosterone to dihydrotestosterone, which may contribute to its therapeutic effects.

This study found no significant differences in sensation recovery or scar formation between radiofrequency and scalpel incisions in upper blepharoplasty, although radiofrequency caused greater tissue damage.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

This source explores long COVID syndrome and identifies risk factors like older age, female gender, and comorbidities such as diabetes. It mentions potential diagnostic biomarkers, highlights ongoing clinical trials, and emphasizes the importance of vaccines and rehabilitation in managing long COVID.
