Stress can cause hair to turn gray by depleting stem cells.

This study highlights that niosomes, or non-ionic surfactant based vesicles, offer an advantageous drug delivery system due to their stability, cost-effectiveness, and ability to enhance drug bioavailability and targeting efficiency for various therapeutic agents.

This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This study found that DGAT1 exhibits additional acyltransferase activities in vitro, including MGAT, wax synthase, and ARAT activities, suggesting these could be relevant to its in vivo functions.

This review discusses the various phenotypes and diagnostic challenges of polycystic ovary syndrome, highlighting its complex pathophysiology and associated health risks, and reports no new clinical results.

This review provides graded evidence and a therapeutic algorithm for managing hidradenitis suppurativa, but does not present new clinical results.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This study demonstrates that bioengineered lacrimal gland germs can successfully develop and restore tear production and ocular surface protection in a mouse model with lacrimal gland dysfunction.

This article reviews recent insights into the regulatory role of reactive oxygen species in plant development, highlighting that their mechanisms and signaling pathways remain partially understood.

This study concluded that albumin-bound testosterone is biologically important and significantly contributes to testosterone bioavailability in women receiving spironolactone.

This manuscript reviews current diagnostic criteria for polycystic ovary syndrome, emphasizing the need for accurate diagnosis in both clinical and research settings, but it does not provide new clinical findings.

This study developed an all-natural hydrogel that promotes diabetic wound healing by converting pro-inflammatory M1 macrophages to anti-inflammatory M2 macrophages in a simple and biosafe manner.

The NAMS 2014 recommendations guide healthcare providers on treating health issues in midlife women, emphasizing individualized care and informed decision-making.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.

This study found that p2y5 functions as a novel LPA receptor involved in the G13-Rho signaling pathway, with implications for human hair growth, and proposes renaming it to LPA6.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This study suggests that human hair follicles may actively suppress natural killer cells, which contrasts with the observed defects in NK cell regulation in alopecia areata.

This review discusses the hypothesis that polycystic ovary syndrome may originate in fetal life due to prenatal androgen exposure, but reports no new clinical results.

The research observed that 40-nm self-assembled nanoparticles enhanced minoxidil penetration in hairy guinea pig skin compared to 130-nm nanoparticles, but this size effect was absent in hairless skin.
