Polysaccharide-Based Injectable Hydrogel Loaded with Quercetin Promotes Scarless Healing of Burn Wounds by Reducing Inflammation

Biomacromolecules, Journal Year: 2024, Volume and Issue: 25(11), P. 7529 - 7542

Published: Oct. 28, 2024

Moisture loss, infection, and severe inflammatory reactions are the primary factors affecting burn wound healing leading to scar formation. Herein, we developed a quercetin-loaded polysaccharide-based injectable hydrogel (named PECE). The PECE consists of oxidized sodium alginate (OAlg) coupled with chitosan (CS) via Schiff bases electrostatic interactions, while Que is incorporated hydrogen bonding. Benefiting from hydroxyl carboxyl groups, features distinguished moisturizing ability. Additionally, sustained release imparts remarkable antibacterial activity against

Metal–Polyphenol–Collagen Self-Assembled Bioadhesive with Immune Regulation for Infected Wound Healing

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(15), P. 9343 - 9352

Published: July 25, 2024

Destroyed skin barriers for extensive cutaneous wounds often bring about delayed healing and even systemic complications. Multifunctional dressing materials targeting different stages of the process have drawn growing concerns to obtain desirable tissue repair. In this study, a self-assembled collagen/tannic acid–zinc (ColTA-Zn) bioadhesive powder with dual cross-linking network was developed infected wound healing. The hydrogen bonds between collagen chains tannic acid, together metal coordination formed by Zn2+ mainly contribute adhesion performances mechanical properties bioadhesive. Furthermore, biocompatible ColTA-Zn exerts antimicrobial effects on Staphylococcus aureus. Crucially, can absorb blood or exudate quickly along rapid gelation adhere surface once contacting wounds, playing roles adsorption, convergence, adhesion. During process, self-gelled exhibits an immunomodulatory effect macrophage polarization ultimately accelerates Therefore, self-assembled, accessible, user-friendly adhesive might be potential candidate dressings adhesive, anti-infectious, conglutinant functions.

Zinc and Metformin Co-Functionalized Polyetheretherketone: A Novel Dental Implant Material Tailored for the Elderly

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 7, 2024

Abstract This study focuses on addressing the challenges of dental implants in geriatric population by enhancing bioactivity polyetheretherketone (PEEK) through surface modification. PEEK, with its elastic modulus close to alveolar bone, mitigates stress shielding but faces limitations osseointegration due low bioactivity. We introduced zinc (Zn) and metformin (MF) onto PEEK surfaces via a dopamine-assisted physical adhesion method, creating functionalized derivative called ZnMF@PEEK. combination targets diminished osteogenic potential, persistent inflammation, cell senescence, which are common issues elderly patients. Comprehensive physicochemical characterizations confirmed successful preparation ZnMF@PEEK, vitro vivo experiments systematically evaluated biocompatibility The results indicate that ZnMF@PEEK holds promise as implant material tailored specific needs elderly, multifaceted osseointegration.
