This study reveals that somatosensory neurons in mouse skin exhibit structural plasticity during hair-follicle regeneration, which may temporarily impair the reliability of encoding gentle touch.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This report presents a rare case of lichen spinulosus in a 52-year-old woman, featuring hyperkeratotic follicular papules and a dense lymphohistiocytic infiltrate in affected skin areas.

A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

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.

In this study, researchers used iron ion coordination to successfully create a molecular knot with three organic ligand strands and eight crossings.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This article discusses traction alopecia in children and adolescents, emphasizing its occurrence due to hairstyles that exert chronic tension on hair, but reports no new findings.

This study demonstrated that RNA-seq can effectively expand hair follicle transcriptomic profiling in a multi-center study, offering deeper insights than blood transcriptomics alone.

This study suggests that increased putrescine levels may disrupt normal hair follicle development in transgenic mice, leading to hair loss and altered skin structure, yet these mice appear more resistant to skin tumorigenesis.

This paper examines factors affecting the stretching setting treatment of human hair and wool, concluding that the intended outcomes can be achieved using their customized testing equipment and technology.

This study used single-cell RNA sequencing to characterize 19 distinct cell populations in sheep hair follicles, uncovering differentiation signatures and intercellular communication that may influence wool curvature and sheep breeding.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

This study documented that human hair shafts exhibit bipolar electrical properties, potentially influencing blood coagulation by inducing fibrin formation through a positive side of the shaft.

This study identified five distinct scalp whorl patterns, noting that white males have the most distinct whorls, while African Americans and women more often exhibit a diffusion pattern.

This study found that bioinspired conductive dressings with aligned wrinkles can monitor joint motion and significantly accelerate wound healing in mice by promoting collagen deposition, hair follicle regeneration, and epithelialization.

This study found that anagen hairs require less force to be extracted than telogen hairs in an in vitro pig skin model, indicating different anchorage mechanisms.

In this study, researchers found that black holes with primary Proca hair exhibit distinctive optical properties, including a two-boundary shadow structure and additional inner rings, offering novel observational signatures and potential insights into strong-gravity environments.

This study observed that human hair macrofibrils predominantly exhibit a double-twist architecture with varying inter-macrofibril angles, advancing insights into their structural organization and mechanical implications.

In this study, cell membrane remodeling with a thermoresponsive boronic acid copolymer was shown to rapidly form spheroids from cancer or cardiac cell lines under standard conditions, promising advances in tissue engineering.

This study found that washing hair after reduction in a permanent waving process allows for significant reformation of disulfide cross-links, enhancing the strength and elasticity of hair fibers.

This article describes a new method for staining hair fibers that visualizes keratin filaments without the need for OsO4 fixation or sulfur bond breakage, but it provides no new experimental results beyond the method itself.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This study found that the methylation level of the IGFBP4 promoter is negatively correlated with mRNA expression and may serve as an epigenetic marker for wool fineness in Super Merino sheep.

Trichodysplasia spinulosa can occur after a heart transplant due to immunosuppressive drugs.

Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

This study found that multi-hair follicles naturally orient perpendicular to the radial line from the crown whirl, suggesting that perpendicular transplantation of grafts could replicate this natural appearance.
