Accelerated glycoxidation takes part in the development of diabetic complications. We determined advanced glycation end-products (AGEs) and advanced oxidation protein products (AOPP) in the sera of 52 patients with diabetes mellitus (DM) - 18 with DM Type 1 and 34 with DM Type 2 and examined their relationship to the compensation of the disease. AGEs were(More)
Alcohol-induced oxidative stress is linked to the metabolism of ethanol. Three metabolic pathways of ethanol have been described in the human body so far. They involve the following enzymes: alcohol dehydrogenase, microsomal ethanol oxidation system (MEOS) and catalase. Each of these pathways could produce free radicals which affect the antioxidant system.(More)
Several diseases (atherosclerosis, diabetes mellitus, chronic renal failure) are associated with oxidative and carbonyl stress, microinflammation and eventually autoimmune reaction. Both oxidative and carbonyl stress cause damage to important biological structures-proteins, carbohydrates, lipids and nucleic acids and may enhance inflammatory response. New(More)
This article represents the proceedings of a workshop at the 2000 ISBRA Meeting in Yokohama, Japan. The chair was Albert Y. Sun. The presentations were (1) Ethanol-inducible cytochrome P-4502E1 in alcoholic liver disease, by Magnus Ingelman-Sundberg and Etienne Neve; (2) Regulation of NF-kappaB by ethanol, by H. Matsumoto, Y. Nishitani, Y. Minowa, and Y.(More)
Receptor for advanced glycation end products (RAGE) may be involved in the pathogenesis of the cancer progression and metastasis. Pathological effects mediated via RAGE are physiologically inhibited by soluble RAGE (sRAGE), so the higher sRAGE levels may confer the patients with cancer with better outcome. The aim was to study sRAGE and RAGE gene(More)
Modification of low density lipoprotein (LDL) particles due to oxidation, glycation and binding of advanced glycation end-products (AGEs) or malondialdehyde (MDA, a final product of lipid peroxidation) is considered most important in the process of atherogenesis. Oxidatively modified LDL are distinguished by another receptor type, which was discovered on(More)
Procalcitonin (PCT) levels can distinguish between infectious and non-infectious systemic inflammatory response. However, there are some differences between Gram-negative (G−), Gram-positive (G+), and fungal bloodstream infections, particularly in different cytokine profiles, severity and mortality. The aim of current study was to examine whether PCT levels(More)
BACKGROUND Advanced glycation end products (AGEs) accumulate in patients with decreased renal function and exert various toxic effects through the receptor for AGEs (RAGE). Soluble RAGE (sRAGE) is a naturally occurring inhibitor of AGE-RAGE action. The aim of the study is to describe the relationship of sRAGE to renal function and dialysis modalities. (More)
BACKGROUND The receptor for advanced glycation end products (RAGE) is involved in the pathogenesis of vascular and inflammatory diseases. The pathological effects mediated via RAGE are physiologically inhibited by soluble RAGE (sRAGE). Our aim was to study sRAGE and RAGE gene polymorphisms in haemodialysis (HD) patients. METHODS A total of 261 stable HD(More)
UNLABELLED Oxidative and carbonyl stress may, on one hand, contribute to the progression of cancer, on the other hand, they may have some antiproliferative effects. We examined serum levels of AGEs (advanced glycation end-products), CML (carboxymethyllysine) and AOPP (advanced oxidation protein products) in 86 patients with breast cancer subdivided based on(More)
