This study suggests that cortisol measured in human hair can effectively reflect increased production for up to six months, but its retrospective accuracy may be limited due to rapid decline in levels.

This article reviews the potential clinical use of anabolic steroids in treating muscle loss from chronic diseases and aging and highlights both the benefits and risks of these substances in sports.

This review focuses on coumarin analogs with potential antibreast cancer activities but reports no new clinical results, highlighting their mechanisms of action and structure-activity relationships.

This review discusses recent advances in surface modification and endothelialization of biomaterials for vascular grafts, highlighting promising methods like gene engineering and targeting ligand immobilization to improve clinical outcomes.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This review discusses the various evidence-based and potential applications of metformin in treating and preventing symptoms and complications associated with polycystic ovary syndrome but reports no new clinical results.

This article reviews the design and objectives of the Rotterdam Study, as well as summarizes major findings, without reporting new results.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study suggests that increased use of anticancer drugs from 2004 to 2008 has led to higher environmental release, necessitating expanded monitoring and research on their ecotoxicological impacts.

In this review, the authors summarize classical and recent insights into the biology and treatment of hypertrophic scars and keloids, concluding that while understanding and strategies have advanced, effective prevention and treatments remain unsatisfactory.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

This study found that TRPA1-deficient mice exhibited normal cold sensitivity but had decreased mechanical response in nociceptors, suggesting TRPA1's role in mechanotransduction.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This review elaborates on the skin side effects of chemotherapy and emphasizes identifying and managing both common and life-threatening skin reactions, without presenting new clinical findings.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This article outlines the rationale and design of the Rotterdam Study, summarizes its major findings, and updates its objectives and methods; it reports no new research results.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

This study found that medium-sized particles (643 and 646 nm) penetrated deeper into porcine hair follicles in vitro than smaller or larger particles, suggesting size-selective targeting within follicular sites.

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 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 review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This article outlines the rationale, design, major findings, and updated objectives of the ongoing Rotterdam Study, without presenting new research data.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This article discusses the rationale, design, major findings, and updated objectives and methods of the ongoing Rotterdam Study on various diseases, without reporting new research results.

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

This study found that recombinant human leukocyte interferon alfa-2a achieved a 64% overall antitumor response rate in patients with early and advanced cutaneous T cell lymphoma and was generally well-tolerated.
