Levels of oxidative damage and lipid peroxidation in thyroid neoplasia
Head & Neck, 2009AbstractBackgroundThis study assessed the presence of oxidative damage and lipid peroxidation in thyroid neoplasia.MethodsUsing tissue microarrays and immunohistochemistry, we assessed levels of DNA damage (8‐oxo‐dG) and lipid peroxidation (4‐HNE) in 71 follicular thyroid adenoma (FTA), 45 papillary thyroid carcinoma (PTC), and 17 follicular thyroid ...

Polyamines reduces lipid peroxidation induced by different pro-oxidant agents
Brain Research, 2004Polyamines, among other functions, are considered to act as a free radical scavenger and antioxidant. The quinolinic acid (QA), sodium nitroprusside (SNP) and iron (Fe+2) stimulate production of free radicals and lipid peroxidation. In the present study, we investigated the free radical and/or aldehyde scavenger effects of polyamines spermine and ...

Oxidative imbalance and lipid peroxidation in Alzheimer's disease
Drug Development Research, 2002AbstractAlzheimer's disease (AD) is a growing serious public health problem worldwide. Clinically, AD is a progressive neurodegenerative disorder characterized by a global cognitive decline. There is significant evidence that reactive oxygen species‐mediated reactions, particularly of neuronal lipids, are extensive in those AD brain areas directly ...

Antipsoriatic drug action of anthralin: Oxidation reactions with peroxidizing lipids
Journal of Free Radicals in Biology & Medicine, 1985Reactions of anthralin with peroxidizing lipids were investigated. Using ESR spectroscopy and quantitative HPLC analysis radical species and decomposition products respectively were analysed in the reaction mixture as a function of time. Directly after mixing anthralin with peroxidized lipids, the 1,8-dihydroxy-9-anthron-10-yl radicals (primary radical)

[Relationship between lipid peroxide oxidation and cell respiration].
Biofizika, 1983A relationship between lipid peroxide oxidation (LPO) in biomembranes and kinetics of oxygen uptake by intact cells and cells under hypotonic shock in the course of their incubation has been studied. Different effect of bivalent ferrum ions--activators of LPO was found; it depended on cell integrity.

Urinary Nitric Oxide Metabolites and Lipid Peroxidation By-Products in Migraine
Cephalalgia, 2003Enhanced endothelium nitric oxide (NO) and superoxide anion release may cause migraine through related cerebral blood flow changes. Thirty subjects suffering from migraine with and without aura and 20 healthy controls were investigated. Urine samples collected for 24 h during and after the migraine attack, and during the headache-free period, were ...

Protein oxidation in thyroid hormone-induced liver oxidative stress: relation to lipid peroxidation
Toxicology Letters, 1999The influence of thyroid hormone administration (daily doses of 0.1 mg of 3,3',5-triiodothyranine (T3)/kg for 1-3 consecutive days) on rat liver protein oxidation was investigated in relation to the calorigenic and lipid peroxidative actions of the hormone.

Oxidative Stress-Induced Lipid Peroxidation: Role in Inflammation
2014Oxidative stress-induced lipid peroxidation is known to produce mediators that are implicated in the pathophysiology of a wide range of inflammatory diseases. In many inflammatory diseases, various lipid-derived aldehydes (LDAs) including 4-hydroxy-trans-2-nonenal (HNE), acrolein, and malondialdehyde (MDA) have been identified.

Oxidation of lipids and membranes I: In vitro formation of peroxidative lipid polymers
Journal of Supramolecular Structure, 1975AbstractFluorescent polymers were obtained by oxidizing partly emulsified linolenic acid with different oxidants. The speed of formation of polymers differed for the various oxidants, and the difference was not a simple function of the oxidation potential.
