Post-traumatic osteoarthritis can develop as a result of the initial mechanical impact causing the injury and also as a result of chronic changes in mechanical loading of the joint. Aberrant mechanical loading initiates excessive production of reactive oxygen species, oxidative damage, and stress that appears to damage mitochondria in the surviving chondrocytes. To probe the benefits of increas...

The cellular protein profiles and malate dehydrogenases, superoxide dismutases, alkaline phosphatases, and esterases from whole cell extracts of Candida spp. were studied with polyacrylamide gel electrophoresis. We investigated isolates that differed in their ability to assimilate sucrose as the sole carbon source. The protein and enzyme patterns of Candida tropicalis and its sucrose-negative v...

In recent years there is an upsurge in the areas related to newer developments in prevention of disease especially the role of free radicals and antioxidants. So it will be pertinent to examine the possible role of ‘free radicals’ in disease and ‘antioxidants’ in its prevention, especially the current status of the subject matter and future prospects. Numerous short-lived and highly reactive ox...

Aerobic growth of Escherichia coli sodAsodB and katE mutants lacking cytosolic superoxide dismutases and catalase hydroperoxidase II was inhibited by osmotic upshift to a greater extent than of their wild-type parent strains. The fur mutation leading to an intracellular overload of iron also increased sensitivity of growing E. coli cells to osmotic upshift. Using lacZ fusions, it was shown that...
