BACKGROUND Angiotensin II-induced hypertension is associated with NAD(P)H oxidase-dependent superoxide production in the vessel wall. Vascular superoxide level is also increased in deoxycorticosterone acetate (DOCA)-salt hypertension, which is associated with a markedly depressed plasma renin activity because of sodium retention. However, the mechanisms underlying superoxide production in low-r...

Chloroacetaldehyde (CAA) is a chlorination by-product in finished drinking water and a toxic metabolite of a wide variety of industrial chemicals (e.g. vinyl chloride) and chemotherapeutic agents (e.g. cyclophosphamide and ifosfamide). In this research, the cytotoxic mechanisms of CAA in freshly isolated rat hepatocytes were investigated.CAA cytotoxicity was associated with reactive oxygen spec...

Increased oxidative stress plays an important role in heavy ion radiation-induced cell death. The mechanism involved in the generation of elevated reactive oxygen species (ROS) is not fully illustrated. Here we show that NADPH oxidase activation is closely related to heavy ion radiation-induced cell death via excessive ROS generation. Cell death and cellular ROS can be greatly reduced in irradi...

Spergualin (SG) and 15-deoxyspergualin (DSG) are derivatives of spermidine. Their substrate and inhibitor activities toward amine oxidase from bovine plasma were determined. SG was a good substrate of amine oxidase next to spermidine. The Km and Vmax for SG were 46.5 microM and 0.429 microM/minute, respectively, whereas the Km and Vmax for spermidine were 111 microM and 3.75 microM/minute, resp...

microcantilevers (mcls) are cost-effective and highly sensitive devices for biodetection. adsorption of specific analytes on the microcantilever surface causes the bending of mcl through changing of the surface characteristics. these new bioprobes designed in a way that one side of the microcantilever surface is coated with a selective receptor that absorbs particular molecules. after surface a...

The losses of molecular activity which take place when cytochrome oxidase is purified from bovine heart muscle particles by the procedures of Yonetani ((1960) J. Biol. Chem. 235, 845) and of Fowler et al. ((1962) Biochim. Biophys. Acto 64, 170) have been examined. Bovine heart muscle particles (about 1 nmole of heme a per mg of protein) and oxidase-rich particles (about 4 nmoles of heme a per m...
