Female Wistar rats, 100 weeks old, were divided into four groups: one group was fed a high-cholesterol diet, one received a non-cholesterol diet, and the others were fed either a non- or a high-cholesterol diet plus docosahexaenoic acid. The level of lipid peroxide (LPO) in brain tissue was measured with a LPO assay kit. Fatty acid concentrations were analyzed by gas chromatography. Brain LPO i...

Bacterial lipopolysaccharide (LPS) causes lipid peroxidation (LPO). We have found that LPS induces LPO in tissue homogenates in vitro in a concentration-dependent manner, the concentration of 400 μg/ml demonstrating the most efficient lipid damaging effect. Antioxidant properties of melatonin are unquestionable and have been proved both in vivo and in vitro. It has been demonstrated that also m...

The purpose of this study was to determine the effect of urinary tract infection (UTI) on antioxidant systems and lipid peroxidation (LPO) levels during pregnancy. We also investigated if these antioxidant systems and LPO levels differed in each trimester. One hundred forty-three nonpregnant women, as a control group, and 77 pregnant women were included in the study. Urine cultures were perform...

CONTEXT Periodontitis is the most common lytic disease of bone and is recognized as a common complication of diabetes. Lipid peroxidation (LPO) is increased in diabetes and may be related to modulation of the inflammatory response. LPO levels in patients with diabetes and periodontal disease have not been evaluated. OBJECTIVE The aim of this study was to evaluate the levels of LPO and its cor...

Lipoxygenase (LPO) metabolites of arachidonic acid participate in the activation and/or proliferation of a variety of cell types. In this study, we examined the role of LPO metabolites in controlling myelopoiesis and erythropoiesis in vitro. Monocyte depleted cells (MDC) prepared from human whole blood or whole mononuclear cells from human bone marrow were cultured in methylcellulose in the pre...

All-solid-state batteries (ASSBs) based on sulphide electrolytes are promising next-generation energy storage systems because they expected to have improved safety, increased volumetric density, and a wide operating temperature range. However, side reactions at the cathode/electrolyte interface deteriorate electrochemical performance limit commercialization of ASSBs. Surface coating cathode is ...

Oxidative damage to macromolecules, including lipids, has been hypothesized as a mechanism of aging. One end product of lipid peroxidation, malondialdehyde (MDA), is often quantified as a measure of oxidative damage to lipids. We used a commercial colorimetric assay for MDA (Bioxytech LPO-586, Oxis International, Portland, OR) to measure lipid peroxidation potential in liver tissue from young (...

Introduction: This study was designed to compare the plasma lipid peroxidation (LPO) levels in preterm and full-term neonates and their respective mothers, to assess their relationship with the degree of oxidative stress and the levels of vitamin C, an important antioxidant of the body. Material and methods: The studied groups included 70 neonates, 30 preterm (24-36 weeks of gestation) and 40 f...

The interaction of a series of derivatives of tyrosine with horseradish peroxidase (HRP) and lactoperoxidase (LPO) was studied by using optical difference spectroscopy, c.d. and proton n.m.r. spectroscopy in order to reveal differences in the mode of binding of L-tyrosine and D-tyrosine, which are substrates of but react at different rates with the two peroxidases, to HRP and LPO. All the donor...
