Reliability of malondialdehyde as a biomarker of oxidative …
网页2015年7月26日 · Malondialdehyde (MDA) is the most frequently used biomarker of oxidative stress in many health problems such as cancer, psychiatry, chronic obstructive pulmonary disease, asthma, or cardiovascular diseases. This perspective study aimed to collect some evidence for low reliability of the MDA as a biomarker of oxidative stress.
[Malondialdehyde (MDA) as a lipid peroxidation marker]
网页Malondialdehyde (MDA) is one of the final products of polyunsaturated fatty acids peroxidation in the cells. An increase in free radicals causes overproduction of MDA. Malondialdehyde level is commonly known as a marker of oxidative stress and the antioxidant status in cancerous patients.
Urinary Malondialdehyde (MDA) Concentrations in the General …
网页2022年3月29日 · It is defined as an imbalance between the production and elimination of reactive oxygen species (ROS). ROS can oxidize proteins, lipids, and DNA, and some of these oxidized products are excreted in urine, such as malondialdehyde (MDA), which is considered a biomarker for oxidative damage of lipids.
Malondialdehyde, a Product of Lipid Peroxidation, Is Mutagenic …
网页Malondialdehyde (MDA) is an endogenous genotoxic product of enzymatic and oxygen radical-induced lipid peroxidation whose adducts are known to exist in DNA isolated from healthy human beings. To evaluate the mutagenic potential of MDA in human cells, we reacted MDA with pSP189 shuttle vector DNA and …
Malonaldehyde - an overview | ScienceDirect Topics
网页Malondialdehyde (MDA), a highly reactive bifunctional molecule, is an end product of membrane lipid peroxidation. MDA has been shown to cross-link erythrocyte phospholipids and proteins. This process results in impairment of the membrane-related functions that ultimately leads to diminished survival.
