BIR, L.S., DEMIR, S., ROTA, S. and KÖSEOĞLU, M. Increased Serum Malondialdehyde Levels in Chronic Stage of Ischemic Stroke. Tohoku J. Exp. Med., 2006, 208 (1), 33-39 ── Serum lipoperoxidation products such as malondialdehyde (MDA) reflect oxidative stress. There are contradictory results addressing the levels of lipoperoxidation products in chronic phase of ischemic stroke. In the present study...

Induction of inducible nitric oxide synthase (iNOS) gene expression, nitric oxide (NO) production and migration of RAW264.7 macrophages by coculture with breast cancer MDA-MB-231 cells or the addition of conditioned medium derived from MDA-MB-231 cells (MDA-CM) was identified. Increased iNOS/NO induction and migration of macrophages by MDA-CM were significantly blocked by adding the c-Jun-N-ter...

RATIONALE It has been proposed that malondialdehyde (MDA) reflects free oxygen-radical lipid peroxidation and can be useful as a biomarker to track this process. For the analysis of MDA molecules in humid air by selected ion flow tube mass spectrometry (SIFT-MS), the rate coefficients and the ion product distributions for the reactions of the SIFT-MS reagent ions with volatile MDA in the presen...

BACKGROUND One potential mechanism for early superficial cartilage wear in normal joints is alteration of the lubricant content and quality of synovial fluid. The purpose of this study was to determine if the concentration and quality of the lubricant, hyaluronan, in synovial fluid: (1) was similar in left and right knees; (2) exhibited similar age-associated trends, whether collected postmorte...

BACKGROUND LDL oxidation in the vascular wall is associated with aldehyde modification of surrounding extracellular matrix proteins that may target autoimmune responses against vascular tissues. Here we investigated the possible influence of immunity against a malondialdehyde (MDA)-modified form of the basement membrane protein laminin on atherosclerosis. METHODS AND RESULTS IgM and IgG autoa...

BACKGROUND As the Global Programme to Eliminate Lymphatic Filariasis (LF) approaches its 2020 goal, an increasing number of districts will enter the endgame phase where drug coverage rates from mass drug administration (MDA) are used to assess whether MDA can be stopped. As reported, the gap between reported and actual drug coverage in some contexts has overestimated the true rates, thus causin...

AIM Triple-negative breast cancer (TNBC), defined by the absence of receptors for estrogen, progesterone and human epithelial receptor 2 (HER2), is a recalcitrant disease in need of effective therapy. We previously isolated very-highly metastatic variants of the TNBC cell line MDA-MB-231 using serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. MATERIALS AND M...

OBJECTIVE To investigate effects of glucose excursion on the oxidative/antioxidative system in subjects with different types of glucose regulation. METHODS A total of 30 individuals with normal glucose regulation (NGR), 27 subjects with impaired glucose regulation (IGR) and 27 subjects with newly diagnosed type 2 diabetes mellitus (T2DM) were selected and recruited for 3 days' continuous gluc...

Lymphatic filariasis (LF) has been targeted for global elimination by 2020. The primary tool for the program is mass drug administration (MDA) with antifilarial medications to reduce the source of microfilariae required for mosquito transmission of the parasite. This strategy requires high MDA compliance rates. Egypt initiated a national filariasis elimination program in 2000 that targeted appr...
