The Role of an Acidic Peptide in Controlling the Oxidation Process of Walnut Oil

Foods, 2019
Here, the mechanism of action of an antioxidant peptide rich in acidic amino acid residues in controlling lipid oxidation is discussed. Firstly, in the presence of this peptide, the fluorescence intensity of lipid peroxide in samples of walnut oil was ...

Lipid peroxidation in eclampsia

Journal of Obstetrics and Gynaecology, 1997
In order to investigate the extent of lipid peroxidation in hypertensive disorders of pregnancy, a case-control study was designed. Eight eclamptic women were matched with women with severe pre-eclampsia (n = 8) and healthy pregnant controls (n = 8).

Unsolved mysteries: How does lipid peroxidation cause ferroptosis?

PLoS Biology, 2018
Ferroptosis is a cell death process driven by damage to cell membranes and linked to numerous human diseases. Ferroptosis is caused by loss of activity of the key enzyme that is tasked with repairing oxidative damage to cell membranes—glutathione ...

Identification of some lipid peroxides by thin-layer chromatography

Journal of Lipid Research, 1965
Solvent systems are described which permit class separations of various peroxidized lipids by thin-layer chromatography. This procedure has proved useful in biological studies and for testing the deterioration of lipids.Proof is given that the least ...

FADS gene polymorphisms in Koreans: association with ω6 polyunsaturated fatty acids in serum phospholipids, lipid peroxides, and coronary artery disease.

Atherosclerosis, 2011
OBJECTIVE We investigated the association of polymorphisms in FADS genes with polyunsaturated fatty acids (PUFAs) in serum phospholipids, lipid peroxides, and coronary artery disease (CAD) in Koreans. METHODS In this case-control study, CAD patients (n=

Tiam1/Rac1 signaling pathway mediates palmitate-induced, ceramide-sensitive generation of superoxides and lipid peroxides and the loss of mitochondrial membrane potential in pancreatic β-cells

Biochemical Pharmacology, 2010
The phagocytic NADPH-oxidase [NOX] has been implicated in the generation of superoxides in the pancreatic β-cell. Herein, using normal rat islets and clonal INS 832/13 cells, we tested the hypothesis that activation of the small G-protein Rac1, which is ...

Superoxide Radicals in the Execution of Cell Death

Antioxidants, 2022
Superoxide is a primary oxygen radical that is produced when an oxygen molecule receives one electron. Superoxide dismutase (SOD) plays a primary role in the cellular defense against an oxidative insult by ROS. However, the resulting hydrogen peroxide is

Beneficial Impact of an Extract from the Berries of Aronia melanocarpa L. on the Oxidative-Reductive Status of the Submandibular Gland of Rats Exposed to Cadmium

Antioxidants, 2020
Oxidative stress underlies the pathomechanisms of toxic action of cadmium (Cd), including its damaging impact on the oral cavity. This study investigated whether the administration of an extract from Aronia melanocarpa L.

The role of non-coding RNA in ferroptosis of liver cancer and its impact on lipid peroxidation

Frontiers in Immunology
Ferroptosis is an iron-dependent programmed death caused by the imbalance of lipid peroxides in cells. Unlike apoptosis, autophagy and necrosis, ferroptosis is mainly induced by the small molecule compound erastin. The main characteristics of ferroptosis
