This study found that electrospun poly(ε-caprolactone)/poly(3-hydroxybutyrate) blend fibers demonstrated nanometric dimensions and promising properties for drug delivery, with curcumin release linked to fiber morphology and processing parameters.

Photocrosslinkable biomaterials can improve wound healing by controlling mechanical environments.

This study found that keratin fibers like human hair undergo thermal and mechanical transitions that can help assess changes from cosmetic processes such as bleaching and perm-waving.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study argues that the reported "toughening" transition in keratin is a misinterpretation, actually representing the evaporation peak of residual water in the fibers.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

African spiny mice can regenerate skin and hair after wounds due to specific tissue mechanics.

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 source describes wound healing as a complex biological process that requires precise regulation and coordination among various cells, cytokines, and signaling pathways to achieve tissue repair, although specific findings or results are not provided in the abstract.

This study found that Caucasian hair is destroyed more easily than Asian hair when stretched, as indicated by changes in secondary structure, disulfide bond breakage, and physical disintegration.

Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.

This study found that overexpressing the PCaP2 protein in Arabidopsis enhanced drought tolerance by influencing ABA and SA signaling pathways and regulating root hair growth, suggesting a key role in water deficit response.

This abstract discusses the importance of thoroughly evaluating donor area characteristics like hair density and scalp elasticity in planning hair transplantation, but it reports no new research findings.

This study demonstrated that hiPSC-derived hair-bearing skin organoids lacked sufficient type VII collagen at the epidermal-dermal junction, indicating a need for further maturation to model certain forms of epidermolysis bullosa effectively.

Hair feels different when touched and rubs together in various ways.

This study observed that beef cattle with certain prolactin receptor gene mutations, known as slick mutations, demonstrated improved post-weaning growth and temperature regulation in a hot, humid climate compared to other genotypes, suggesting genotype influences growth efficiency and heat tolerance.

Integumentary organs adapt and evolve for survival, with potential uses in regenerative medicine.

In this study, children's hair showed statistically higher elasticity than elderly hair, but no significant differences were observed in tensile strength between dietary or oil application groups, or between pigmented and nonpigmented hair.

This study found that mouse hair follicle stem cells in a quiescent state exhibit greater chromatin dynamics and de-differentiation potential, suggesting higher cell fate plasticity compared to their proliferative or differentiated counterparts.

This study suggests that low phosphorus and ethylene may influence root hair density through separate pathways, with ethylene manipulation affecting root hair growth in Arabidopsis thaliana.

This study found that bovine slick mutations may enhance heat stress responses in mice but do not lead to the expected hair phenotype changes.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This study demonstrated that alkali-modified Kapok fiber significantly enhances the adsorption of collagen, suggesting its potential application in collagen-based dressings.

This study identified novel isoforms of the PADI2 and PADI3 proteins, showing that PADI2β inhibits oligodendrocyte differentiation, possibly by opposing the effect of canonical PADI2, while PADI3β modulates the activity of PADI3α, suggesting new regulatory mechanisms of citrullination in tissue development.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This study developed mathematical models to simulate phosphate uptake in rice and Arabidopsis, suggesting a phosphate-sensitive repressor could regulate PHO2 mRNA levels, and highlighting potential targets and traits for improving phosphorus-use efficiency.

This study found that in adult mouse skin, somatosensory axon plasticity is highly dynamic and influenced by epithelial-neural crosstalk and intrinsic neural mechanisms.

In this study, researchers used embryonic chicken skin as a model to show that perturbing calcium signaling can induce feather bud formation in areas that typically do not form them, highlighting developmental bioelectricity as a crucial yet underexplored layer in tissue patterning.

This mini-review explores how both endogenous and damage-released RNAs serve as instructional signals that influence cell identity and plasticity during tissue maintenance and repair, highlighting RNA's role as a regulator of cellular flexibility in various regenerative contexts.
