Organic peroxides inhibit neutrophil leukotriene B4 biosynthesis

, 1992
Leukotriene B4, an autacoid metabolite of arachidonic acid produced by polymorphonuclear neutrophils, induces chemokinesis, chemotaxis, and adhesion of these cells at sites of inflammation.

Methionine-SAM metabolism-dependent ubiquinone synthesis is crucial for ROS accumulation in ferroptosis induction

Nature Communications
Ferroptosis is a cell death modality in which iron-dependent lipid peroxides accumulate on cell membranes. Cysteine, a limiting substrate for the glutathione system that neutralizes lipid peroxidation and prevents ferroptosis, can be converted by cystine

Lipid Peroxides and α-Tocopherol in Rat Streptozotocin-Induced Diabetes Mellitus

Measurement of lipid peroxides and alpha-tocopherol was undertaken in rats with streptozotocin-induced diabetes. In sera and livers in diabetic rats, the lipid peroxides increased but alpha-tocopherol decreased.

Generation of reactive oxygen species and formation of membrane lipid peroxides in cells infected with Chlamydia trachomatis

, 2000
Objectives: Chlamydiae are obligate intracellular pathogens that cause many diseases for which the pathogenic mechanisms are largely unknown. Because reactive oxygen species (ROS) have been implicated in pathogenesis of many viral and bacterial ...

The influence of vitamin C and E use on concentration of endothelin-1 and lipid peroxides in the serum of pregnant women with arterial hypertension

, 1970
Introduction: Hypertension occurs in 6 to 10 percent of pregnancies. It remains one of the most common disorders in pregnancy and the leading causes of maternal and fetal morbidity.

Lipid peroxides and glutathione status in human progenitor mononuclear (U937) cells following exposure to low doses of nickel and copper

, 2012
Effects of Cu2+, Ni2+ or Cu2+ + Ni2+ on lipid peroxide and glutathione (GSH) levels in U937 cells were investigated. Cells were treated with 0, 5, 10, and 20 µM of Cu2+ and/or Ni2+ and H2O2 (0.01 mM) and incubated for 24 hours at 37°C.

Pigmentation, carotenoids, lipid peroxides and lipid composition of red porgy (Pagrus pagrus) skin reared under open-cage conditions

, 2010
Pigmentation capability of red porgy (Pagrus pagrus) skin reared under open sea-cage conditions and fed an astaxanthin-enriched diet was studied. Skin lipid peroxide levels and lipid composition were also evaluated to establish the antioxidant role of ...

Changes of lipid peroxides and alpha-tocopherol in rats with experimentally induced myocardial necrosis.

Myocardial necrosis was produced in rats by injection of isoproterenol (80 mg per kg body weight). Lipid peroxides were measured by the thiobarbituric acid reaction. alpha-Tocopherol was assayed by fluorometric analysis.

Histochemical Localization of Xanthine Oxidase and Lipid Peroxides in Rat Myocytes

, 1988
Because xanthine oxidase (XO) induced H202 formation has been implicated as a source of free radicals and a cause of reperfusion injury, a histochemical method was developed to visualize the location of XO dependent production of H202 and the location of
