Using computational methods to design patient-specific electrospun cardiac patches for pediatric heart failure
Biomaterials. 2022 Feb 18;283:121421. doi: 10.1016/j.biomaterials.2022.121421. Online ahead of print.ABSTRACTAutologous cardiac cell therapy is a promising treatment for combating the right ventricular heart failure (RVHF) that can occur in patients with congenital heart disease (CHD). However, autologous cell therapies suffer from low cell retention following injection and patient-to-patient variability in cell quality. Here, we demonstrate how computational methods can be used to identify mechanisms of cardiac-derived c-Kit+ cell (CPC) reparative capacity and how biomaterials can be designed to improve cardiac patch perf...

Dexamethasone-conjugated polyethylenimine/MIF siRNA complex regulation of particulate matter-induced airway inflammation.
Abstract Inhalation of airborne particulate matter (PM), such as silicon dioxide (SiO2) and titanium dioxide (TiO2), induces acute lung inflammation. siRNA therapy has been proposed as a method to repair acute lung inflammation. To determine whether DEXA-PEI/MIF siRNA contributes to SiO2-induced acute lung inflammation repair, we administered Dexa-PEI/MIF siRNA in SiO2-treated Beas-2b cells and instilled DEXA-PEI-MIF siRNA intratracheally in mice with SiO2-induced acute lung inflammation. Using genetic (MIF mRNA RT-PCR), histological (H&E and PAS) and immunohistochemical (MIF and Muc5ac) analyses, we estimated...
