Pro-/anti-oxidative properties of dopamine on membrane lipid peroxidation upon X-ray irradiation

Differential effects of carotenoids on lipid peroxidation due to membrane interactions: X-ray diffraction analysis.

The biological benefits of certain carotenoids may be due to their potent antioxidant properties attributed to specific physico-chemical interactions with membranes. To test this hypothesis, we measured the effects of various carotenoids on rates of lipid peroxidation and correlated these findings with their membrane interactions, as determined by small angle X-ray diffraction approaches. The e...

Sperm lipid peroxidation and pro-inflammatory cytokines.

AIM To investigate if interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), interferon-gamma (IFN-gamma) or tumor necrosis factor-alpha (TNF-alpha) are able to stimulate the level of lipid peroxidation of sperm membranes, either alone or in the presence of leukocytes. METHODS Semen samples from normozoospermic donors were prepared by density gradient. The sperms were exposed to ...

Ameliorating effects of genestein: Study on mice liver glutathione and lipid peroxidation after irradiation

Background: Genistein is a soya isoflavone, which is found naturally in legumes, such as soybeans and chickpeas. Radiation–induced free radicals in turn impair the antioxidative defense mechanism, leading to an increased membrane lipid peroxidation that results in damage of the membrane bound enzyme and may lead to damage or death of cell. Hence, the lipid peroxidation is a good biomar...

Lipid Peroxidation and Membrane Aging

This critique points out that a number of possible alterations in cell metabolism could lead to changes in membrane structure and that the observed effects might not necessarily play a primary role in the physiology of aging. Experimental approaches, while not simple, should distinguish causes of altered membrane asymmetry from its consequences. THE idea that cross-linking agents might play a r...
