Oxidant signals and oxidative stress
Current Opinion in Cell Biology, 2003Although oxidants clearly possess the capacity to behave in a random and destructive fashion, growing evidence suggests that in many instances the production of reactive oxygen species is tightly regulated and their downstream targets exquisitely specific.

Oxidative stress is two sided: Whereas excessive oxidant challenge causes damage to biomolecules, maintenance of a physiological level of oxidant challenge, termed oxidative eustress, is essential for governing life processes through redox signaling.

Modelling oxide–oxide and oxide–metal interfaces
J. Chem. Soc., Faraday Trans., 1990Recent years have seen a large increase in interest in interfaces of ionic and ceramic crystals and an appreciation of their importance in determining many of the properties of materials. Static-lattice calculations have made a major impact on the interpretation of the role of point defects in controlling observed behaviour in the bulk and are now ...

Abstract: The oxidative modification of proteins by reactive species, especially reactive oxygen species, is implicated in the etiology or progression of a panoply of disorders and diseases. These reactive species form through a large number of physiological and non‐physiological reactions.

The understanding of the role of lipoprotein oxidation is still incomplete. Much is still to be learned about the mechanism of action of oxidized lipoproteins on different types of cell, as well as the origin of the oxidation process, and how it links to the situation in vivo.

Abstract: There is a large body of evidence showing both metabolic defects and oxidative damage in Alzheimer's disease. Studies of cybrid cell lines show reduced cytochrome oxidase. There is also substantial evidence for a defect in a‐ketoglutarate dehydrogenase.

The immediate source of energy for muscle contraction is provided by the hydrolysis of adenosine triphosphate (ATP). However, muscle ATP stores are not large and would be consumed in only a few seconds of high-intensity exercise if they were not quickly replenished.

Current Protocols in Cytometry, 1997
AbstractPeroxide production is detected using DCFH‐DA, superoxide anion by hydroethidine; the methods can be combined for simultaneous detection. A support protocol describes calibration of the flow cytometer to permit calculation of the actual H2O2 production per cell.

Oxidation and oxidation protection
1993Over the past decade the development of structural carbon-carbon materials has received a great deal of attention. Potential uses have been cited in future generation military aircraft, missile systems and a number of proposed hypersonic aerospace vehicles.
