Methods Heparinized blood specimens obtainedfrom normal adult subjects were
centrifuged and the buffy coat and supernatant plasma were removed. The isolated cells …

Oxidation and oxygenation reactions involving molecular oxygen (dioxygen) are universally
important for aerobic organisms, but, paradoxically, the cellular utilization of oxygen poses …

Hydrogen peroxide is an oxidising agent that is used in a number of household products,
including general-purpose disinfectants, chlorine-free bleaches, fabric stain removers …

To investigate the function of antioxidant enzymes in intact cells, we examined the removal
of extracellular H2O2 by cultured fibroblasts (IMR-90). H2O2 concentration dependence of …

Using the glucose oxidase system as the source of H2O2, the accuracy and reliability of the
horseradish peroxidase (HRP)-scopoletin method for measuring H2O2 were critically …

One of the objectives of studying endothelial cells in vitro is to evaluate neutrophil-
endothelial cell interactions including potential consequences of oxidant-mediated damage …

The field of oxygen study is immense. No single work on the subject can be comprehensive,
and this volume makes no such claim. Indeed, coverage here is selective and the selection …

Background Controlled generation and removal of hydrogen peroxide play important roles
in cellular redox homeostasis and signaling. We used a hydrogen peroxide biosensor …

The redox potential of• O 2− was determined based on the dependence of the electron
transfer reaction from• O 2− upon the known redox potential of various acceptors A …

Chemistry and Cellular Sources of Oxygen Radicals Reduction of molecular oxygen (O2) by
addition of a single electron results in formation of the superoxide (Of) anion [1]. In aqueous …
