Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This study demonstrated that using a perfusion culture bioreactor and 3D spheroid culture can enhance corneal endothelial cell expansion and support the construction of tissue-engineered corneal endothelial layers in vitro.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This study found that using nanoporous silica entrapped lipid-drug complexes enhanced the solubility and bioavailability of dutasteride in beagle dogs.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This study fabricated a polyamide fiber containing amber particles and characterized its potential for textile applications, noting that the chemical structure of amber remained unchanged after grinding and integration.

This study reported that metallic-glass-coated tattoo needles reduced trauma and improved tattoo quality in pig skin experiments compared to uncoated needles.

This study used a multi-point tension test method to evaluate hair damage over time and found it useful for assessing the effects of cosmetics and metal content on hair strength.

In this experimental study, researchers developed and optimized metformin-loaded mucoadhesive microspheres for sustained anti-hyperglycemic and anticancer activity, demonstrating high entrapment efficiency, enhanced α-amylase and α-glucosidase inhibition, improved cytotoxicity against breast cancer cells, and promising stability.

This study observed that biodegradable PVA/agar films with incorporated Achillea millefolium L. essential oil, especially at 1% (v/v), demonstrated good mechanical performance and selective antibacterial activity against E. coli, suggesting their potential as wound dressings.

This study found that a bioactive borosilicate glass containing Sr and Cu ions exhibited promising mechanical strength, biocompatibility, and antibacterial activity, particularly the CuSr-1 wt.% composition, suggesting potential for use in orthopedic implants and bone tissue engineering.

This study found that Si extract, cryptomeridiol, and SiAgNPs have the ability to induce cell death and prevent cell growth in HepG2 liver cancer cells, suggesting cryptomeridiol's potential as a phytochemical component in developing new therapies for hepatocellular carcinoma using nanotechnology in vitro.

This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This study found that chitosan microparticles containing minoxidil sulphate sustained its release and may hold potential for targeted topical treatment of alopecia.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This study developed thermo-reversible glycol chitosan hydrogels that effectively form and maintain 3D cell spheroids within one day, offering a simplified method for creating biologically realistic cultures for tissue regeneration and drug screening applications.

This study found that daily use of 1% pyrithione zinc shampoo modestly improved hair growth over 26 weeks, although these effects were less than those of 5% minoxidil.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

In this study, the Selenium-Chitosan-Mupirocin nanohybrid system significantly enhanced wound healing in a rat model of diabetic wound infection compared to the control, suggesting potential for treating mild diabetic wounds.

This report describes two children with congenital hypotrichosis and found their short hair is due to a shortened anagen phase, with the condition resolving spontaneously during puberty.

In this study, researchers developed a wearable red and blue LED patch and a sprayable fibrin gel to treat infected wounds at home, demonstrating effective infection control and enhanced wound healing in diabetic mice and minipigs.

This study suggests that adjusting the ratios of keratin-associated proteins to keratin intermediate filaments can create keratin/chitosan hydrogels with more consistent gel properties for tissue engineering.

This study demonstrates that transfected epidermal stem cells using a novel 3D transfection system significantly enhanced wound healing and may serve as an effective therapeutic agent and gene delivery method for wound treatment.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.
