In this study, molecular dynamics simulations indicated that the Glu413Lys mutation in human hair keratin significantly affects the stability of coiled coil structures, whereas Glu413Asp showed no impact on stability.

This study found that patients with alopecia areata atopica and other skin conditions had lower hair magnesium levels compared to healthy controls, although the differences largely overlapped.

This study found that desmosomal cadherin desmoglein 3 loses its rigidity upon Ca2+ removal, regardless of desmosome functional state, suggesting a central role for signaling in hyper-adhesion.

A higher calcium to magnesium ratio in hair is linked to lower insulin sensitivity.

Merkel cells likely attract sensory nerve fibers.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study developed a mathematical model indicating that the amino acid sequences of intermediate filament proteins, rather than flexibility differences, significantly impact assembly rates.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This case report describes a patient with adrenomyeloneuropathy, highlighting unusual MRI findings of high signal areas in the right striatum.

This study proposed that the tiger tail phenomenon in trichothiodystrophy hair is caused by regular undulations of hair fibers, altering the optical properties seen under polarized light.

Method quickly measures finasteride concentration in capsules.

This study found that moose hair can effectively monitor previous mineral states for most elements, except zinc, and mineral uptake differs between male and female moose.

This study demonstrated that exposing hair follicle organ cultures to extremely low-frequency electromagnetic fields at 10 G intensity for 60 minutes promoted hair growth, suggesting its potential as a treatment for hair loss.

This study found that treating hair with 1 M sodium hydroxide increases its self-friction coefficient, suggesting potential applications in forming fine frictional fibers for medical uses.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

This study found distinct hair metal profiles in Parkinson's disease patients, with lower iron and copper, higher manganese and arsenic, and explored their link to gut dysfunction and microbiota dysbiosis, suggesting hair metal analysis as a promising diagnostic tool.

A new, quick method accurately detects minoxidil in drugs and cosmetics.

This study found that hair manganese levels did not vary by acute coronary syndrome or stable coronary artery disease severity, but a modest, non-significant correlation with body mass index suggests a potential link between manganese homeostasis and cardiometabolic status that warrants further investigation.

This study introduced a new computational method for simulating vibrational frequencies, finding that the multi-molecular fragment model showed the best agreement with experimental data for Finasteride, Lamivudine, and Repaglinide, outperforming traditional models in accuracy.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study introduces a new intracavity frequency modulation technique for tunable picosecond optical parametric oscillators, enhancing chemical contrast in coherent Raman imaging by allowing real-time subtraction of background signals.

This review discusses past research on the chemical and physical properties of human hair, focusing on structural analysis and mechanical property measurements with methods like SEM and tension tests, but adds no new findings.

This study used atomic force microscopy to image surface structures of human epidermal melanocytes, hair follicle amelanotic melanocytes, and mouse melanoma cells, revealing differences in branch structure and granule distribution.

Mouse hair element patterns vary, making it unreliable for tracking time.

This study found that electroosmotic flow through hair follicles significantly contributes to solution flow during iontophoresis in hairless mouse skin.
