introduction: electromagnetic fields (emfs) can influence the biological system by the formation of free radicals in cells. the emfs are able to deteriorate defense system against free radicals that leads to oxidative stress (os). lipid peroxidation process (lpo) is an index of oxidative stress, and the malandialdehyde (mda) is the final product of lpo. vitamin e is the most important antioxida...

4-Hydroxy-2-nonenal, an indicator of lipid peroxidation process. was used as model marker to explore ceftriaxone-induced lipid peroxidation in goat liver homogenate. Ceftriaxone was found to induce lipid peroxidation significantly. It was further found that ascorbic acid could significantly arrest ceftriaxone-induced lipid peroxidation. The results corroborate the earlier findings with malondia...

Lipid peroxidation can be defined as the oxidative deterioration of lipids containing any number of carbon-carbon double bonds. Lipid peroxidation is a well-established mechanism of cellular injury in both plants and animals, and is used as an indicator of oxidative stress in cells and tissues. Lipid peroxides are unstable and decompose to form a complex series of compounds including reactive c...
