Blood flow through intrapulmonary arteriovenous anastomoses (IPAVA) is increased by acute hypoxia during rest by unknown mechanisms. Oral administration of acetazolamide blunts the pulmonary vascular pressure response to acute hypoxia, thus permitting the observation of IPAVA blood flow with minimal

Although the existing theories have predicted enhancement of electrophoretic mobility of microparticles near a solid wall, the relevant experimental studies are rare. This is mainly due to difficulties in experimentally controlling and measuring particle-wall separations under dynamic electrophoretic conditions. This

Retinal angiogenesis, neural dysfunction, and microglial activation occur in both humans with retinopathy of prematurity and in animal models of the disease. The aim of this study was to assess whether blockade of the renin-angiotensin system ameliorated these effects in
