Applications of Chitosan and its Derivatives in the Treatment of Osteoarthritis.

Osteoarthritis (OA) is a common joint disease, which is mainly characterized by the degeneration of articular cartilage, inflammation of the synovial membrane of the joint, and changes in the surrounding bone tissue. With the increase of age and weight, the incidence of OA gradually increases, which seriously affects the quality of life of patients. The primary pharmacological treatments for OA include analgesics and non-steroidal anti-inflammatory drugs.

Synchronously Tailoring Strain Sensitivity and Electrical Stability of Silicone Elastomer Composites by the Synergistic Effect of a Dual Conductive Network.

The use of conductive polymer composites (CPCs) as strain sensors has been widely investigated. A wide range of strain sensitivities and high repeatability are vital for different applications of CPCs. In this study, the relations of the conductive filler network and the strain-sensing behavior and electrical stability under fatigue cycles were studied systematically for the first time based on the conductive polymethylvinylsiloxane (PMVS) composites filled with both carbon nanotubes arrays (CNTAs) and carbon black (CB).
