This study found that a highly resistant structure, located at the interface between the cuticle and cortex of human hair, acts as a penetration barrier, which the authors propose to name the "cuticle anchored resistant base" or CARB.

This study found that mice lacking both vitamin D and calcium-sensing receptors in epidermal keratinocytes are predisposed to developing squamous cell carcinoma as they age, due to impaired oxidative stress response and reduced DNA repair capabilities.

Treat limited stage small cell lung cancer with chemotherapy and radiation, and consider preventive brain radiation for better survival chances.

This study found that simultaneous presence of specific and nonspecific skin lesions, or having three or more types of skin lesions, was associated with increased systemic activity of systemic lupus erythematosus.

This study developed and validated a UV spectrophotometric method for accurately measuring finasteride and tamsulosin in solutions and tablets, demonstrating good sensitivity and precision.

This study demonstrated that CD anisotropy effectively distinguishes between two polymorphs of finasteride with nearly identical electronic circular dichroism spectra, using imaging and simulated spectra to uncover unique signatures that traditional methods miss.

This study found that octahydrobenzo[c]quinolizin-3-one derivatives, particularly compound 3, were potent and selective inhibitors of the enzyme 5α-reductase type 1.

This study found significant associations between PCOS susceptibility and specific genetic variants in the APOA5 and PLIN1 genes among Western Saudi women, identifying novel alleles and genotypes that may influence PCOS risk and related clinical characteristics.

This study validated a new RP-HPLC method for accurately determining doxazosin mesylate and finasteride in bulk powders and capsule formulations.

This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

This article reviews the classification, pathogenesis, and treatment options for cutaneous lupus erythematosus and reports no new clinical findings.

This research discusses Stevens-Johnson syndrome and toxic epidermal necrolysis, life-threatening conditions often induced by immune-mediated drug reactions. Optimal management involves early diagnosis, drug withdrawal, and supportive therapy, though evidence for systemic treatments like corticosteroids and cyclosporin remains variable and lacks randomized controlled trial confirmation.

This subject index from the book "Stem Cells in Toxicology and Medicine" offers no new research results.

This case report describes a 64-year-old woman who developed delusions after starting citalopram, highlighting citalopram-induced psychosis in older adults as a potential but rare side effect.

This review discusses Cronkhite-Canada syndrome, highlighting a relatively mild case and suggesting that it may be a more benign and possibly reversible condition with treatment, but reports no new clinical results.

This study found that poly(butylene citramalate-co-butylene succinate) copolymers exhibit high toughness, recyclability, degradability, and biocompatibility, achieving complete wound healing with skin and hair follicle regeneration in 7 days.

This abstract provides contact information for François Kuonen at the Lausanne University Hospital Center and reports no new research findings.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This study identified NM_026333 as a potential anti-aging gene that, when induced, may alleviate proton-induced aging symptoms in CF6-overexpressing and high salt-fed mice.

This study explores the role of cell competition in maintaining genomic quality in epidermal stem cells and proposes that this process might influence cancer development in skin tissues.

Corkscrew hair may be a new sign for quickly diagnosing scalp fungus in black children.

This case report details a 71-year-old man diagnosed with Cronkhite-Canada Syndrome, highlighting the importance of early diagnosis and endoscopic evaluation due to the disease's progressive nature and significant mortality risk.

This study identified CYP3A4 as a key isozyme involved in the oxidative metabolism of finasteride in human liver microsomes.

This study found that CPA-loaded nanoparticles, particularly SLN formulations, increased CPA epidermal penetration compared to a conventional cream and may reduce side effects in treating androgen-dependent conditions.

ATP-sensitive potassium channels are important for hair growth.
