Mitochondrial substrate oxidation-dependent protection against lipid peroxidation
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1982The effect of mitochondrial substrate oxidation on the NADPH-dependent lipid peroxidation of intact mitochondria, microsomes and of homogenate from rat liver was studied. It was found that addition of either succinate or beta-OH-butyrate decreased the rate of malondialdehyde production of mitochondria. The effect of succinate was found to be marked (80-

Lipid peroxidation products as oxidative stress biomarkers
BioFactors, 2008AbstractOxidative stress induced by reactive oxygen and nitrogen species has been implicated in the pathogenesis of various disorders and diseases. Biomarkers are needed for assessment of oxidative stress status in vivo and also for health examination, diagnosis at early stage, prognosis, safe and efficient drug development, and evaluation of efficacy ...

Oxidant-antioxidant enzymes and lipid peroxidation in generalized vitiligo
Clinical and Experimental Dermatology, 2004Vitiligo is a common pigmentary disorder of the skin with selective destruction of melanocytes. The pathogenetic mechanisms in vitiligo have not been completely clarified. The aim of our investigation was to evaluate the oxidative stress in the pathogenesis of generalized vitiligo. Twenty-seven patients with generalized vitiligo and 24 phototype-, age-,

Oxidative stress, lipid peroxidation and premature placental senescence in preeclampsia
Archives of Biochemistry and Biophysics, 2022Accelerated placental senescence is associated with preeclampsia (PE) and other pregnancy complications. It is characterized by an accelerated decline in placental function due to the accumulation of senescence patterns such as telomere shortening, mitochondrial dysfunction, oxidative damages, increased expression of phosphorylated (serine-139) histone

Oxidation of ferrous iron during peroxidation of lipid substrates
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1987Oxidation of Fe2+ in solution was dependent upon medium composition and the presence of lipid. The complete oxidation of Fe2+ in 0.9% saline was markedly accelerated in the presence of phosphate or EDTA and the ferrous oxidation product formed was readily recoverable as Fe2+ by ascorbate reduction.

Methods for monitoring oxidative stress, lipid peroxidation and oxidation resistance of lipoproteins
Clinica Chimica Acta, 2001After a brief discussion of lipid peroxidation mechanism and the action of antioxidants and their potential to exhibit prooxidant effects, we give an overview on the clinical relevance of oxidative stress parameters. Many diseases are associated with oxidative stress e.g.

Lipid peroxidation in the presence of iron oxides
Toxicological & Environmental Chemistry, 2000Exposure to iron oxides dusts may lead to lung cancers among exposed population. To evaluate the involvement of iron‐containing particles in lipid peroxidation by production of reactive oxygen species, hematite, magnetite (iron oxides), and crocidolite (asbestos compound) were tested.

[Nitric oxide and lipid peroxidation].
Comptes rendus des seances de la Societe de biologie et de ses filiales, 1996Nitric oxide (NO) is a free radical produced enzymatically in biological systems from the guanidino group of L-arginine. Its large spectrum of biological effects is achieved through chemical interactions with different targets including oxygen (O2), superoxide (O2o-) and other oxygen reactive species (ROS), transition metals and thiols.
