Unique promotion of erythrophagocytosis by malondialdehyde

American Journal of Hematology, 1988
AbstractModification of the normal erythrocyte membrane by reagent malondialdehyde (MDA) promotes phagocytosis of red blood cells by human macrophages, a phenomenon previously shown to involve both IgG‐dependent and IgG‐independent mechanisms and to be demonstrable even at micromolar MDA concentrations.

Distribution and oxidation of malondialdehyde in mice

Prostaglandins, 1985
The in vivo metabolism of malondialdehyde (MDA) by male and female Swiss mice was investigated. Distribution of an i.p. dose of MDA is rapid and uniform throughout the body. Conversion of 14C-labeled MDA to CO2 is complete 4 hours after an i.p. dose of 5 mumol to 200 mumol with no signs of short term toxicity.

Malondialdehyde, modified lipoproteins, and atherosclerosis

European Heart Journal, 1990
It is likely that identification of the mechanisms releasing malondialdehyde and other peroxidative decomposition products in the arterial wall will provide new insights into the sequence of biochemical and cellular events in the pathogenesis of atherosclerosis and ultimately may lead to development of strategies for the intervention and reduction of ...

Malondialdehyde determination in raw and processed meat products by UPLC-DAD and UPLC-FLD.

Food Chemistry, 2019
The objective of this study was to develop an accurate and fast method to determine malondialdehyde (MDA) levels in raw and processed meat. This method is based on extraction with trichloroacetic acid (TCA), reaction with 2-thiobarbituric acid (TBA) and ...

Proinflammatory effects of malondialdehyde in lymphocytes

Journal of Leukocyte Biology, 2012
Abstract MDA changed cytokine/chemokines mRNA profiles in lymphocytes; increased cytokines expression is via oxidative stress, p38MAPK, and PKC pathways. Diabetes is an inflammatory disease promoted by alterations in immune cell function.

Malondialdehyde formation in stored plasma

Biochemical and Biophysical Research Communications, 1980
Summary The formation of malondialdehyde in plasma during storage was used as an indicator of lipid peroxidation. Malondialdehyde concentrations were measured in plasma stored at 4°C in the presence of various preservative reagents. A rapid rate of formation of malondialdehyde (15.0 ± 14.0 nmol/dl/week) was observed in control plasma preserved with ...

Vortex-assisted liquid-liquid microextraction based on hydrophobic deep eutectic solvent for determination of malondialdehyde and formaldehyde by HPLC-UV approach

Microchemical journal (Print), 2018
A simple, and cost-effective vortex-assisted liquid-liquid microextraction (VALLME) based on hydrophobic deep eutectic solvent (DES) has been developed to extract malondialdehyde (MDA) and formaldehyde (FA) after derivatization with 2,4 ...

Electronic spectroscopy of malondialdehyde

Chemical Physics Letters, 1976
Abstract The electronic absorption spectra of malondialdehyde in vapor and solutionphases and derived monoanion in solution are presented. Comparison of CNDO/s-CI computations with experiment allows two singlet—singlet transitions at λ ⩾ 1800 A to be assigned within the G 4 molecular symmetry group description of the planar non-rigid neutral ...

Malondialdehyde Contents in Infant Milk Formulas

Journal of Agricultural and Food Chemistry, 2004
Malondialdehyde (MDA) levels in infant milk formulas have been monitored by using an aqueous acid extraction method combined with the thiobarbituric acid method (TBA-test). Vegetable oils, with a remarkable content of polyunsaturated fatty acids (PUFA) are used to enrich the infant milk formulas. As PUFA are more susceptible to autoxidation, it becomes
