A new method strengthens hair without using harmful chemicals.

This research observed that 3D electrospun micro/nanofibrous sponges, without using chemical crosslinking agents, supported enhanced cell growth, vascularization, and skin regeneration in diabetic rats compared to 2D fiber membranes, making them promising for 3D tissue regeneration.

This study investigated the formation of a specific chemical crosslink in hair proteins and explored the role of transamidase enzymes in hair follicles.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

This study reports two distinct patterns of hair changes in postmenopausal women, linking diffuse generalized scalp hair loss to older age and frontal hair loss to higher facial hair scores and younger age.

This study explored using tyrosine as a cross-linking agent for curling Asian hair and found that it could shape hair effectively before washing without damaging the fibers, though the method was less effective after washing compared to commercial products.

This review discusses the chemical stability of protein envelopes found in the epidermis and other stratified squamous epithelia, but reports no new clinical results.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

This study analyzed social media posts to assess pet toxicosis from topical minoxidil exposure, finding that many pet owners were unaware of its toxicity risks, particularly for cats, and highlighted a significant need for increased educational efforts to prevent such incidents.

The document concludes that hair keratin-chitosan scaffolds were successfully made and are suitable for biomedical use.

This study found that a unique transglutaminase in guinea pig hair-follicles, distinct from liver transglutaminase, likely plays a role in forming protein cross-links via ε(γ-glutamyl)lysine bonds.

In this study, researchers used 3D printing combined with cryogenic crosslinking to develop gelatin/oxidized alginate scaffolds and found that adding 5% hydroxyapatite improved mechanical properties and osteogenic effects, enhancing bone tissue regeneration, though 10% hydroxyapatite offered no additional osteogenic benefits and reduced shape fidelity.

This review explores how recombinant protein hydrogels, employing molecular engineering and crosslinking strategies, offer advanced applications in regenerative medicine by mimicking extracellular matrix dynamics and providing enhanced mechanical, environmental, and biological properties.

This research provides insights into how keratin hydrogels, modified to control disulfide crosslinking, may function as a treatment platform for bone injuries.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

This study introduces a novel in vitro model for clubfoot fibrosis to enable high-throughput drug screening and found that while the model increased collagen deposition, the antifibrotic drug minoxidil effectively inhibited the expression of collagen cross-linking enzymes.

In this study, early prenatal treatment with Minoxidil, a lysyl hydroxylase inhibitor, partly improved cardiac outflow tract septation in Tbx1 mutant mice, suggesting that inhibiting collagen cross-linking may mitigate some effects of Tbx1 mutation associated with DiGeorge syndrome.

This review discusses the potential of electrospun gelatin-based nanofiber dressings for wound healing and skin regeneration, detailing their properties, enhanced functionalities through crosslinking and bioactive components, and their application in treating challenging wound types like burns and diabetic wounds.

In this study, researchers developed an acellular bioscaffold made from ovine tendon collagen with an antibacterial coating for treating skin wounds. They found that genipin crosslinking improves the scaffold's properties, and with plasma polymerisation, it enhances antibacterial activity, potentially benefiting wound healing.

In this study, a novel CT@GA-gel hybrid hydrogel was developed for diabetic wound treatment, demonstrating improved mechanical properties, tissue adhesion, and chronic wound healing benefits, including immune regulation and re-epithelialization, due to enhanced crosslinking and ROS scavenging by incorporated carbon dots.

This pilot study suggests that high-dose testosterone plus finasteride improved knee extensor strength and muscle size in men with impaired gait after chronic incomplete spinal cord injury.

This article comments on previous studies linking severe androgenetic alopecia to increased vulnerability to COVID-19 and highlights ongoing research into antiandrogen therapies as potential treatments.

This study purified a transglutaminase enzyme from human epidermis that requires calcium or strontium for activity and forms cross-linked polymers, but its detailed activation mechanism remains unclear.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

This study observed that a peptide showed higher antioxidant and metal ion chelation activity compared to its encapsulated version cross-linked in calcium alginate beads.

In this study, applying the microbial enzyme transglutaminase from Streptomyces mobaraensis to damaged hair increased its tensile strength by 15.64%, suggesting potential benefits in repairing shampoo-induced damage and improving hair luster.

This study found that frequent lupus flare-ups, hair loss, hospitalization, and fatigue significantly impacted depression, anxiety, and socioeconomic coping, while having supportive friends reduced these emotional challenges.

This study developed a hydrogel from glycol chitosan and silica nanoparticles, which showed promise in wound healing by supporting microvessel and hair follicle growth in skin defects.

This meta-analysis utilized genome-wide association data to explore the genetic traits related to perceived youthfulness across different sex groups in the UK Biobank, incorporating factors like facial aging and lifestyle habits, but the abstract does not report specific results.
