Finasteride forms three new products under acidic stress.

In this study, the authors found that inhibiting Cdc42 activity with CASIN restored hair follicle stem cell function and hair growth in aged mice, suggesting potential for treating aging-related hair regeneration issues.

This study found that hyperproliferative stimuli dysregulated the balance of stem cell divisions in keratinocytes, suggesting potential treatment strategies for both benign and cancerous hyperproliferative diseases.

This study determined the crystal structure and conformation of synthesized 17x-Acetoxy-pregn-4,6-diene-3,20-dione, revealing specific molecular interactions and structural details in an orthorhombic crystal system.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

This study examined finasteride degradation under stress conditions, identifying three unique degradation products in acidic environments, providing insights into impurity profiling and quality control for finasteride formulations.

This comprehensive guide from nanotechsci.com explores how nanocrystal technology enhances the bioavailability of poorly water-soluble pharmaceuticals, detailing the science behind crystallization and practical synthesis techniques, and discussing their advanced drug delivery applications across various routes.

This article reviews central centrifugal cicatricial alopecia, including its various forms and potential multifactorial causes, but provides no new clinical findings.

This study found that laccase-assisted grafting of poly(tyrosine) onto wool materials improved shrinkage resistance and mechanical properties while causing minor decreases in crystallinity and thermal resistance, suggesting a potential "green" approach to enhance wool durability.

This study reported that antimicrobial and topical retinoid therapies led to significant changes in the lipid profiles of sebaceous follicular infundibulum, with increased triglycerides and ceramide subfractions observed.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This study found that mutations in the PADI3 gene, which is important for hair shaft formation, may contribute to central centrifugal cicatricial alopecia among patients.

This study observed that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments; linear filaments stabilize fused membranes, while branched filaments, connected by the protein Ezrin, drive integration, demonstrating actin's role in adapting to membrane biophysical changes.

This study developed an in vitro model using human follicular keratinocytes to observe selective cell growth and differentiation, potentially aiding future research on hair biology and growth processes.

This study explored using tyrosine as a cross-linking agent for curling Asian hair and found that it could shape hair effectively before washing without damaging the fibers, though the method was less effective after washing compared to commercial products.

This study presents a method for extracting and measuring cyclic AMP in small amounts of skin tissue, finding varying levels in the dermis, epidermis, and hair follicles.

This study proposes reclassifying PCOS into two distinct phenotypes based on androgen levels and suggests androgen supplementation may overcome IVF resistance in one group with advancing age.

This article reviews the diagnostic challenges of polycystic ovary syndrome in adolescents, discussing criteria, symptoms overlap with normal puberty, and treatment strategies, but it reports no new clinical findings.

In this study, researchers developed a microfluidics-based method for creating uniform, size-controlled stem cell spheroids that enhance osteogenic differentiation when encapsulated in alginate-RGD microgels.

This article reviews polycystic ovary syndrome in adolescents, highlighting its endocrine and metabolic features, and reports no new clinical findings; the etiology may involve early-life abnormalities in androgen production.

In this study, cyclosporin A treatment significantly increased hair length in nude mice compared to controls, but hair growth reversed after treatment stopped.

This study found that topical application of bovine milk polar lipids accelerated hair cycle progression in mice, showing potential for use in cosmetic products.

In this study, TyroSpheres were used to encapsulate adapalene, increasing its solubility and enhancing skin distribution while reducing irritancy compared to a commercial formulation, indicating promise for acne treatment in ex vivo and in vitro settings.

This study introduces the concept of teloptosis, which influences hair shedding during the telogen phase and affects hair density, highlighting that early or delayed teloptosis has noticeable effects.

This study observed that enzyme activity influencing estradiol-to-estrone conversion in Wistar rat skin varied with the hair cycle in dorsal skin but was minimal in plantar skin.

This study argues that the reported "toughening" transition in keratin is a misinterpretation, actually representing the evaporation peak of residual water in the fibers.

Activating autophagy in hair follicle stem cells can lead to hair growth and repair by affecting sugar metabolism.
