The transformation of macrophages into lipid-loaded foam cells is a critical early event in the pathogenesis of atherosclerosis. Both receptor-mediated uptake of modified LDL, mediated primarily by scavenger receptors-A (SR-A) and CD36 along with other proteins such as lipoprotein lipase (LPL), and macropinocytosis contribute to macrophage foam cell(More)
We examined in vitro antioxidant capacity of polyphenolic extract obtained from the wood of oak Quercus robur (QR), Robuvit, using TEAC (Trolox equivalent antioxidant capacity) method and the effect of its intake on markers of oxidative stress, activity of antioxidant enzymes, and total antioxidant capacity in plasma of 20 healthy volunteers. Markers of(More)
Statins (HMG-CoA reductase inhibitors) represent a major class of compounds for the treatment of hypercholesterolemia due to their ability to inhibit de novo cholesterol synthesis. In addition to their hypolipidemic effects, chemoprotective properties have been attributed to statins as well. These effects involve multiple mechanisms, which, however, are not(More)
PURPOSE In this study, we focused on the effect of hyperglycemia on the generation of reactive oxygen species and on the release of pro-inflammatory cytokines in the human monocytic cell line (U937). We also monitored potential anti-inflammatory effects of walnut oil as well as its protective effect against oxidative damage to biopolymers (DNA and(More)
The aim of our study was to estimate cytostatic/cytotoxic activity of the copper(II) Schiff base complex of the composition [Cu(N-salicylidene-l-glutamato)(H2O)2]·H2O, further Cu(SG-L)H2O, against human colon carcinoma cell line HT-29, as well as to determine type of cell death and to find out the molecular mechanism of apoptosis induced by this complex.(More)
BACKGROUND Autophagy plays an important role in cancer cells. Targeting autophagy in cancer can provide new opportunities for drug development. METHODS In this study we tested four Schiff base Cu(II) complexes against human breast cancer cells (MCF-7) and human non-cancerous cells (HEK-293T). We have tested their cytotoxic effect by evaluating IC50 using(More)
Diabetes-related complications, including cardiovascular disease, retinopathy, nephropathy, and neuropathy, are a significant cause of increased morbidity and mortality among people with diabetes. Previous studies have confirmed that hyperglycemia has pro-oxidative and proinflammatory properties which cause diabetic complications. We hypothesized that(More)
We have focused on determining the range of oxidative stress biomarkers and their dynamic changes in patients at different time points after the acute ischemic stroke (AIS). 82 patients with AIS were involved in our study and were tested: within 24 h from the onset of the attack (group A); at 7-day follow-up (group B); and at 3-month follow-up (group C). 81(More)
CONTEXT Methylation reactions are particularly important in the brain and their inhibition can lead to a number of serious pathologies. Multiple sclerosis is one of the most common neurological disorders caused by interaction of genetic and environmental factors, but little is known about its cause or factors that contribute to the disorder. Although(More)
Schiff base copper (II) complexes are known for their anticancer, antifungal, antiviral and anti‑inflammatory activities. The aim of the current study was to investigate biological effects of Schiff base Cu (II) complexes (0.001‑100 µmol/l)‑[Cu2(sal‑D, L‑glu)2(isoquinoline)2]·2C2H5OH (1), [Cu(sal‑5‑met‑L‑glu)(H2O)].H2O (2),(More)
