Polysaccharide-Based Coating with Excellent Antibiofilm and Repeatable Antifouling-Bactericidal Properties for Treating Infected Hernia.

In recent years, the utilization of medical devices has gradually increased and implantation procedures have become common treatments. However, patients are susceptible to the risk of implant infections. This study utilized chemical grafting to immobilize polyethylenimine (QPEI) and hyaluronic acid (HA) on the surface of the mesh to improve biocompatibility while being able to achieve antifouling antimicrobial effects.

Growth characteristics of and mechanical properties of slope with different sludge contents.

The utilization of dredged sludge can reduce environmental pollution and save land resources. To explore using sludge resources in ecological slope-protection projects, dredged sludge was incorporated into ecological slope-protection soil. was planted to analyze the effect of sludge content on its growth.
