This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study found that Fos protein expression is closely linked to epithelial cell differentiation, particularly during cornification and cell death, with overexpression observed in keratinization-blocked mutant epidermis.

This study concluded that allele-specific PCR (AS-PCR) is more reliable than tetra-primer ARMS-PCR for genotyping the SNP rs1998076 due to better stability and interpretability.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study found that patients with androgenetic alopecia, particularly those with a U pattern, are prone to insulin resistance, with high fasting blood sugar and triglyceride values.

In this study, trichoscopy was found to be an effective noninvasive tool for diagnosing female pattern hair loss at early stages, potentially eliminating the need for scalp biopsies.

In this study, researchers identified a novel homozygous variant in the FAM83G gene responsible for autosomal recessively inherited palmoplantar keratoderma with curly hair in a consanguineous Pakistani family, suggesting FAM83G plays a crucial role in skin and hair homeostasis.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

Hair changes may indicate disease activity in pemphigus patients.

In this study, researchers found that the congenital absence of the palmaris longus muscle was relatively uncommon and showed no significant differences according to sex, side, or digit ratio (2D:4D) among individuals assessed using MRI and radiographs.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This study found that Turkish women with female pattern hair loss had significantly lower mid-scalp hair density and anagen ratio compared to healthy controls, with digital image analysis underestimating hair density.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This study identifies specific trichoscopic features such as empty follicles and perifollicular erythema in Caucasians with frontal fibrosing alopecia, which may assist in diagnosis and monitoring, but stresses the need for further research due to limited demographic data.

This review describes trichoscopy features of lichen planopilaris and frontal fibrosing alopecia, identifying distinct patterns that help differentiate the two conditions.

This study reports an improved method for determining blood type from human hair using immunohistochemistry.

This study observed that the expression of certain keratins during human epidermal development marks the tissue's commitment to stratification and keratinization processes.

Hair movement can indicate hair quality and health.

This study identified SFRP2 and PTGDS as potential biomarkers for female pattern hair loss, finding these genes consistently upregulated in bald hair follicles from all 18 patients, which may contribute to understanding the condition's pathogenesis and developing targeted treatments.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

This study reported that in women with pattern baldness, hormonal levels and iron deficiency were significantly associated with the condition, but trichoscopic findings were similar across different forms of female pattern hair loss.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.

This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

This review covers the basic principles of forensic hair analysis, including how chemical substances get incorporated into hair, and emphasizes its applications in disease diagnosis, without providing new experimental results.
