In this study, researchers identified two types of potassium channels, BK and Kv4.2, in rat Merkel cells and reported that these channels play important roles in repolarizing action potentials and maintaining resting membrane potentials, potentially influencing tactile encoding in these cells.

This study revealed that frizzled 3 can fully rescue polarity defects in frizzled 6-null mice, while frizzled 6 can partially rescue defects in frizzled 3-null mice, highlighting conserved signaling roles in these proteins.

This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.

In this research, the author hypothesizes that curly hair is influenced by the contraction of the Arrector Pili muscle, suggesting that its relaxation through specific treatments could potentially modulate hair follicle curvature, but further studies are needed to confirm this mechanism.

This study found that enzymatic phosphorylation of hair keratin increased its capacity to adsorb cationic components like methylene blue and may have practical implications for hair care products.

This study found that sodium and potassium hair levels may serve as sex-specific indicators, with slight differences in copper and iron content between males and females, particularly during the female reproductive period.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This study found that serum and hair mineral concentrations, including copper and zinc, showed no differences between Alzheimer's patients and their healthy spouses, suggesting no diagnostic utility for Alzheimer's disease.

This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.

In this study, researchers used the Modified Transient Plane Source method to measure the thermal conductivity of human hair, highlighting that common heat treatments can damage hair structure by altering its protein composition, emphasizing the importance of understanding thermal properties to mitigate such damage.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.

This study observed that cancer patients had significantly lower immunity and higher virus infection and zinc levels in hair compared to those with benign tumors and healthy subjects.

This study found that while hair washed with hard water had higher magnesium deposits, it did not show significant structural surface changes compared to hair washed with soft water.

This study in western Hudson Bay, Canada, examined trace elements in the hair of adult male polar bears and found significant differences in concentration patterns along the hair length, suggesting laser ablation ICP-MS is a promising tool for monitoring these variations over time.

This study observed that hair cuticles experience greater water-induced plasticization than hair cortex, affecting the torsional rigidity of hair fibers, which may help predict hair setting behavior.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This pilot study found no significant relationship between blood and hair mineral concentrations in generally healthy adults, though hair analysis may have potential for assessing long-term mineral trends.

This study suggested that MRF may support skin regeneration and rejuvenation by promoting collagen synthesis and regulating factors involved in fibroblast activation and ECM remodeling, with preliminary findings indicating ADSCs might aid these processes.

In this in vitro study, pretreatment with Dead Sea water and saline magnetized water reduced UVB-induced DNA damage and inflammation markers in human keratinocyte cells, primarily through autophagy activation, suggesting potential use in topical products to prevent skin damage from UV exposure.

Keratin heterodimers are preferred for their specific and structural advantages.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This study found that multi-hair follicles in nonbald men are primarily oriented perpendicular to the radial line from the crown whorl, suggesting perpendicular transplant grafts might mimic natural appearance.

This study found that the levels of heavy metal contamination in hair were higher in both men and women with hair loss compared to those without.

MRI helps distinguish between pituitary adenomas and craniopharyngiomas, guides treatment for pediatric CNS tumors, and assesses rhinocerebral mucormycosis with a high mortality rate in transplanted patients.

This research analyzed two ancient mammoth hair strands and reported distinct structural and elemental differences, including calcium, iron, and copper deposits, which vary with age and origin.

In this study, particles similar in size to keratin cells were surprisingly found to penetrate more efficiently into hair follicles due to a possible pumping effect from moving hairs.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

This review discusses forensic DNA phenotyping, focusing on male pattern baldness and its prediction through SNP markers, but reports no new results.
