In this study, lower dihydrotestosterone and higher testosterone levels were linked to increased brain activation during response inhibition, although no behavioral changes were detected.

This case report suggests that 1064 nm picosecond Nd:YAG laser therapy may effectively improve alopecia totalis when used as an alternative adjuvant treatment, as demonstrated in a split-scalp study showing better results than steroid treatment alone.

This review discusses the potential of lecithin organogels for improving topical drug delivery and presents no new experimental results; the authors highlight their stability and low skin irritancy as advantages.

This study suggests that adding metformin to diet and exercise improves insulin resistance and hyperandrogenism in women with PCOS, though lifestyle changes alone may enhance menstrual cycles.

This review discusses the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This article reviews the use of cross-sex hormonal therapy in transmen and reports that it is reasonably safe, suggesting monitoring should be frequent initially but can be less frequent over time.

This review explores the therapeutic potential of bee venom for treating various skin diseases, discussing its mechanisms and effects but reports no new clinical findings.

This review presents the practice of using hair bioelement analysis to assess nutritional status or environmental exposure, proposing complex interactions and hypotheses regarding depression and autism but reports no new clinical results.

This review discusses recent findings on pathogenic mechanisms, diagnostic criteria, and treatment options for PCOS but reports no new clinical results.

In this study, researchers analyzed over 5,000 T cells per sample using scRNA+TCR-seq technology and found that dual TCR Tregs are present in high proportions across various mouse tissues, showing unique TCR pairing patterns, V(D)J usage, and mRNA expression compared to single TCR Tregs.

This review examines the traditional uses and biological activities of Glycyrrhiza glabra in Ayurveda, but reports no new clinical results; the authors identify a gap in evidence supporting its medicinal potential.

This study found that deleting ceramide synthase 4 in skin epidermis stem cells disrupts hair follicle and skin barrier function, leading to immune responses similar to atopic dermatitis, due to imbalances in lipid composition affecting differentiation.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

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.

In this study, fingertip regeneration in mice was associated with specific signaling pathways involving hair follicles and hedgehog signaling, with potential implications for improving human hand injury treatments.

This review discusses the role of hair follicles in wound healing and scar remodeling, emphasizing that hair follicle transplantation may aid in faster wound closure and scar reduction by enhancing the cellular and molecular mechanisms involved in scarring.
