Despite the widespread use of general anesthesia, a growing body of research suggests that anesthesia exposure early in life may be associated with acute neurotoxicity and lasting behavioral changes. To better evaluate the risk posed by early life anesthesia on cognitive development, infant rhesus monkeys were exposed to an anesthesia regimen previously shown to be neurotoxic and their cognitive development was subsequently measured using a translational operant test battery. On postnatal day 5 or 6, animals were exposed to 8 h of isoflurane (n = 6, 1% isoflurane in a vehicle gas of 70% nitrous oxide and 30% oxygen) or a control condition (n = 8). Read More

While the progress of China’s industrialization and urbanization has made great strides, atmospheric pollution has become the norm, with a wide range of influence and difficult governance. While many previous works on NOx pollution have been developed from the perspectives of natural science and technology, few studies have been conducted from social-economic points of view, and regional differences have not been given adequate attention in driving force models. This paper adopts China’s provincial panel data from 2006 to 2015, an extended STIRPAT (Stochastic Impacts by Regression on Population, Affluence and Technology) model, and spatial econometric models to investigate the socio-economic influential factors and spatial-temporal patterns of NOx emissions.

We recently found that renal carbonic anhydrase (CA) is involved in the reabsorption of inorganic nitrite (NO), an abundant reservoir of nitric oxide (NO) in tissues and cells. Impaired NO synthesis in the endothelium and decreased NO bioavailability in the circulation are considered major contributors to the development and progression of renal and cardiovascular diseases in different conditions including diabetes. Isolated human and bovine erythrocytic CAII and CAIV can convert nitrite to nitrous acid (HONO) and its anhydride NO which, in the presence of thiols (RSH), are further converted to S-nitrosothiols (RSNO) and NO.
