Determination of the Mechanism of Free Radical in Human Aortic Endothelial Cells Exposed to Anoxia and Reoxygenation
(The Journal of Biological Chemistry, 1994-09-30)
Endothelial cell-derived oxygen free radicals are important mediators of postischemic injury; however, the mechanisms that trigger this radical generation are not known, and it is not known if this process can occur in ...
Measurement of Oxygen Concentrations in the Intact Beating Heart Using Electron Paramagnetic Resonance Spectroscopy: A Technique for Measuring Oxygen Concentrations in Situ
(Journal of Bioenergetics and Biomembranes, 1991-12)
Electron paramagnetic resonance (EPR) spectroscopy can be applied to measure oxygen concentrations in cells and tissues. Oxygen is paramagnetic, and thus it interacts with a free radical label resulting in a broadening of ...
