GELMA/PEGDA MICRONEEDLES PATCH LOADED WITH HUVECS-DERIVED EXOSOMES AND TAZAROTENE PROMOTE DIABETIC WOUND HEALING

GelMA/PEGDA microneedles patch loaded with HUVECs-derived exosomes and Tazarotene promote diabetic wound healing

Abstract Clinical work and research on diabetic wound repair remain challenging globally.Although various conventional wound dressings have been continuously developed, the efficacy is unsatisfactory.The effect of drug delivery is limited by the depth Pool Cleaners of penetration.The sustained release of biomolecules from biological wound dressings

Theoretical and Numerical Investigation of Reduction of Viscous Friction in Circular and Non-Circular Journal Bearings Using Active Lubrication

Reducing friction losses is one of the most common ways to improve fluid film bearings, whose adjustable design provides additional opportunities to improve their dynamic and tribological properties.Previous studies have shown the possibility of reducing viscous friction in actively lubricated bearings by adjusting the rotor position.This work prov
