This animal and in vitro study evaluated a composite osteochondral scaffold with bone marrow mesenchymal stem cells (BMSCs) combined with low-frequency electromagnetic field (EMF) stimulation. The authors report that EMF promoted BMSC proliferation and chondrogenic differentiation in vitro, partly via PI3K/AKT/mTOR…

This in vitro materials study compares microwave irradiation versus conventional water-bath heating for synthesizing HPMC-graft-(PVA-co-acrylic acid) hydrogels loaded with captopril. The authors report that microwave-synthesized hydrogels had more uniformly porous structures and higher swelling ratios, with…

This engineering study reports optical and electrical characteristics of photonic gel cells made from a PS-b-P2VP lamellar film and a hydrogel electrolyte on ITO glass. Applying 2 V between two facing electrodes over 30 minutes shifted the device reflectance peak from 538 nm up to 604 nm with limited bandwidth…
