This study shows that microdiffraction experiments reveal structural layers in keratinous tissues, each with different keratin types, potentially explaining their dual role as mechanical support and chemical barriers.

This article reviews a tabletop microscopy method for recording electromagnetic radiation from tissues, using hair follicles as a model, and presents no new clinical findings.

This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study describes a fast LC/MS/MS method for detecting various synthetic drugs in urine, meeting World Anti-Doping Agency performance limits.

This article shares the author's personal reflections on medico-legal issues encountered in the field of cosmetic surgery and aesthetic dermatology, but does not present new research findings.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

QMSI effectively maps and quantifies drug distribution in skin tissues.

This overview describes the Dermatologic Surgery journal's comprehensive coverage of dermatologic surgical procedures, but it reports no new research findings.

The book provides updated methods for skin research and treatment.

This study developed a validated method using UPLC-MS/MS to analyze 37 hormones in human hair, enabling broader hormonal profiling for identifying endocrine disorders.

This study introduces a novel non-invasive method called "differential stripping" to quantify the penetration of topically applied substances into hair follicles.

This study developed a synchronized fluorescence spectroscopic approach to quantify finasteride and tadalafil in various forms, achieving high accuracy with %recoveries of about 99.62% and 100.19% respectively, and demonstrated superior environmental friendliness compared to previous methods.

This study found that histomorphological evaluation of nail punch biopsies is useful for diagnosing various nail-related dermatoses, with psoriasis being the most common condition observed.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This study identified two types of calcium in human scalp hair shafts: easily removable calcium, likely as calcium soaps, and more stably bound calcium, possibly related to Ca-binding proteins.

In this study, the researchers found that an increased number of hairs less than 40 microns in diameter per cm² was associated with androgenic alopecia in both men and women.

This study developed and validated a method using UPLC-PDA and LC-Q-TOF/MS to identify and measure prohibited substances in dietary supplements, showing reliable detection of compounds like minoxidil and finasteride.
