Valve replacement for critical heart valve diseases is in many cases not an option. Our clinical experience in pediatric compassionate care has shown robust function of porcine small intestinal submucosa (PSIS) valves. We assessed functional effectiveness of 4ply (~320µm) and 2ply (~166µm) PSIS mitral valves under pediatric-relevant hemodynamic pulsatile conditions. Key conclusions: (i)PSIS valves demonstrated statistically similar acute functionality in comparison to a commercially available valve. (ii)Energy losses were similar (p>0.05) under pediatric conditions which was not the case under adult aortic conditions. (iii)2ply valves were observed to be superior to 4ply, based on the robust hydrodynamic data, the …

The efficient treatment of cancer with chemotherapy is challenged by the limited penetration of drugs into the tumor. Nanoparticles (10 – 100 nanometers) have emerged as a logical choice to specifically deliver chemotherapeutics to tumors, however, their transport into the tumor is also impeded owing to their bigger size compared to free drug moieties. Currently, monolayer cell cultures, as models for drug testing, cannot recapitulate the structural and functional complexity of in-vivo tumors. Furthermore, strategies to improve drug distribution in tumor tissues are also required. In this study, we hypothesized that hyperthermia (43°C) will improve the distribution of silica nanoparticles …
