Antibodies to malondialdehyde (MDA)-modified macromolecules (adducts) have been detected in the serum of patients with atherosclerosis and correlate with the progression of this disease. However, the epitope and its formation have not been characterized. Studies have shown that excess MDA can be degraded to acetaldehyde, which combines with proteins to from a stable dihydropyridine adduct. To i...

Purpose. To compare serum levels of malondialdehyde (MDA) in patients with wet age-related macular degeneration (wAMD), patients with dry AMD (dAMD), and patients without AMD and to evaluate the efficacy of nutritional supplementation for treating elevated serum MDA in patients with wAMD. Methods. MDA levels were measured in sera from 20 patients with wAMD, 20 with dAMD, and 24 without AMD. Pat...

OBJECTIVE In this study, we aim to demonstrate that measurement of the malondialdehyde (MDA) level in the umbilical cord blood of newborn infants born via cesarean section (C/S) and normal vaginal delivery (NVD) is indicative of oxidative stress during the perinatal period. METHODS The study was conducted at Bakirkoy Training and Research Hospital between January 2006 and April 2006 on 15 new...

BACKGROUND We aimed to evaluate urinary MCP-1 and oxidative stress through urinary malondialdehyde (MDA) in leprosy and correlate them with traditional, but less sensitive markers of renal disease. METHODS This is a cross-sectional study of 44 patients with diagnosis of leprosy and no previous treatment. Skin smear was assessed through a bacteriological index - from 0 to 6+. Glomerular filtra...

Serous ovarian cancer (SOC) is usually diagnosed at late stage and stage-adjusted five year survival rate is low. Mortality is relatively heavy on African-Americans/Black (AA) affected with SOC compared to their Caucasian counterparts, though the cause for the disparity remains unclear. DNA damage induced by oxidative stress has been linked to ovarian cancer, but the role of oxidative stress in...

ABSTRACTBackground: Antioxidant is a substance that can catch and neutralize free radicals so the process of oxidative stress be stopped cell damage avoided. Kaffir lime peel contains antioxidant compounds have potential to neuroprotective agent protect neurons from radical-induced damage.Objective: To evaluate effect kaffir extract (Citrus hystrix) on plasma malondialdehyde (MDA) level mice in...

Pyridostigmine bromide, a reversible anticholinesterase drug, was used by military personnel during the Gulf War. They were under physical stress and might have been exposed to low-dose nerve gas, sarin. This study examined the interactions of low-dose sarin and pyridostigmine in exercised mice. Male NIH Swiss mice were treated as follows: 1) Control; 2) Sarin (0.01 mg/kg, sc); 3) exercise; 4) ...

An imbalance between oxidative stress and antioxidant capacity has been proposed to play an important role in the development and progression of chronic diseases in the elderly. The present study was carried out to investigate correlation between the serum antioxidants (lycopene and alpha-tocopherol) and malondialdehyde (MDA), a marker of oxidative stress in the healthy Thai elderly. The 207 he...

BACKGROUND Obesity is associated with increased oxidative stress and lipid peroxidation is thought to play a crucial role in the generation of atherosclerotic lesions of Acute Myocardial Infarction (AMI). METHODS The case-control study contained 120 subjects divided in two groups, 60 patients with AMI and equal number of age- and sex-matched healthy subjects as controls. Ratio of Waist Circum...

In the present study, toxic effects of glyphosate on Allium cepa L. (Amaryllidaceae) cells were investigated. For this aim, we used the germination percentage, root length, seedling weight, malondialdehyde (MDA) level, frequency of micronucleus (MN), chromosomal aberrations (CAs) and mitotic index (MI) as indicators of toxicity. In addition to the analyses mentioned above, we also examined chan...
