Sb(V) Reactivity with Human Blood Components: Redox Effects
We assessed the reactivity of Sb(V) in human blood. Sb(V) reactivity was determined using an HPLC-HG-AFS hyphenated system. Sb(V) was partially reduced to Sb(III) in blood incubation experiments; however, Sb(III) was a highly unstable species. The addition of 0.1 mol L(-1) EDTA prevented Sb(III) oxidation, thus enabling the detection of the reduction of Sb(V) to Sb(III). The transformation of S...
متن کاملCompact NMR relaxometry of human blood and blood components
Nuclear magnetic resonance relaxometry is a uniquely practical and versatile implementation of NMR technology. Because it does not depend on chemical shift resolution, it can be performed using low-field compact instruments deployed in atypical settings. Early relaxometry studies of human blood were focused on developing a diagnostic test for cancer. Those efforts were misplaced, as the measure...
متن کاملRedox status and pulmonary vascular reactivity.
Oxygen radicals are produced during oxidative metabolism in proportion to the tissue oxygen tension. The studies reported here have shown that oxygen radicals or the sulfhydryl oxidant, diamide, caused pulmonary vasodilatation in the isolated perfused rat lung. Could oxygen radicals play a role in the physiologic control of pulmonary vascular smooth muscle tone?
متن کاملHuman sickle cell blood modulates endothelial heme oxygenase activity: effects on vascular adhesion and reactivity.
OBJECTIVE Sickle cell disease (SCD) is characterized by extensive hemolysis, increased cellular adhesion, and vaso-occlusion. Tissues from sickle patients express heme oxygenase-1 (HO-1), the enzyme that degrades free heme/hemoglobin to the signaling molecule carbon monoxide, and the antioxidants biliverdin/bilirubin. Here, we examined the HO response in endothelial cells exposed to human sickl...
متن کاملCirculatory and renal effects following transfusion of human blood and its components to dogs.
The cardiovascular effects of the transfusion of human blood and of some of its components were studied in dogs. Human blood, hemoglobin, globin and red cell stroma produced significant circulatory depression. The reaction to stromal materials was considered to represent a combination of peripheral pooling and myocardial depression. The reactions to human hemoglobin and globin indicated primary...
