Arteriovenous fistula (AVF) is frequently believed to be the best vascular access for chronic renal failure (CRF) patients. Vascular endothelial cell dysfunction has been implicated in AVF maturation. Quercetin (Quer) is a natural polyphenolic compound widely used in traditional Chinese medicine. We aimed to uncover the impacts of Quer on vascular endothelial cells in a CRF rat model and human umbilical...
In the proton exchange membrane fuel cell (PEMFC) for vehicles, the changes in gas composition and oxygen accumulation may exist during the parking process even by using a shut‐down strategy of oxygen consumption, which can lead to the hydrogen/air interface. However, this process of oxygen accumulation is often ignored. Thus, in this work, the diffusion rate of the gas, the gas composition changes,...
