Lipid peroxidation in spermatozoa
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1973Abstract Ram spermatozoa produce aerobically an organic peroxide which can be determined quantitatively by the thiobarbituric acid reaction. The reaction is more intense in spermatozoa that have been stored at 5°C. Cold shock and homogenization release from spermatozoa a substance, presumably a lipid, which provides the substrate for

Peroxidation of liposomal lipids
European Biophysics Journal, 2007Free radicals, formed via different mechanisms, induce peroxidation of membrane lipids. This process is of great importance because it modifies the physical properties of the membranes, including its permeability to different solutes and the packing of lipids and proteins in the membranes, which in turn, influences the membranes' function. Accordingly,

Inhibition of lipid peroxidation
Biological Trace Element Research, 1997Lipid peroxy radicals (ROO.) were detected by electron spin resonance (ESR) at low temperature after formation by addition of H2O2 into a suspension of mice lymphocytes. If lymphocytes were treated with selenomethionine (Se-Met) prior to addition of H2O2, ROO. formation was inhibited in a fashion that was dependent on Se-Met concentration. Formation of

Lipid Peroxidation in Diabetes Mellitus
Antioxidants & Redox Signaling, 2005There is considerable evidence that hyperglycemia represents the main cause of complications of diabetes mellitus (DM), and oxidative stress resulting from increased generation of reactive oxygen species plays a crucial role in their pathogenesis. In fact, in the absence of an appropriate response from endogenous antioxidant mechanisms, the redox ...

Paraquat and Lipid Peroxidation
Archives of Internal Medicine, 1982To the Editor. —In the AugustArchives(1981;141:1169-1171), Yasaka et al reported an increase in lipid peroxidation (as measured by serum malondialdehyde levels) after ingestion of paraquat, a bipyridinium compound widely used as a herbicide. The authors suggested that the serum malondialdehyde may have originated from passage of the blood through the ...

Assays for the Measurement of Lipid Peroxidation
2012Physical and emotional stress, metabolic alterations, carcinogenesis or inflammation are conditions that can trigger oxidative stress, which is defined as a balance shift of redox reactions towards oxidation, resulting in the increase of reactive oxygen species (ROS). ROS are continuously formed in small quantities during the normal metabolism of cell,

Abstract Lipid peroxides are major primary products of lipid peroxidation. Measurement of lipid peroxides in in vitro experiments or biological samples is often required to assess the extent both of oxidative damage and of changes in antioxidant activity. Various methods have been proposed and used, but each method has both merits and
