The role of the innate immunity during human ageing is not well understood. The aim of the study was to estimate reactivity of NK (natural killer) cells in the very old (mean age 91 years) and old subjects (mean age 78 years) compared to young individuals (mean age 26 years) in respect to the indices of the oxidative stress (telomere length of NK cells,(More)
Common molecular changes in cancer cells are high carbon flux through the glycolytic pathway and overexpression of fatty acid synthase, a key lipogenic enzyme. Since glycerol 3-phosphate dehydrogenase creates a link between carbohydrates and the lipid metabolism, we have investigated the activity of glycerol 3-phosphate dehydrogenase and various lipogenic(More)
BACKGROUND/AIMS The aim of this study was to explain the molecular basis for elevated concentrations of circulating triglycerides (TAGs) after partial surgical removal of adipose tissue (lipectomy) in rats. METHODS The levels of mRNA and protein: a) involved in synthesis of fatty acids and TAGs; b) participating in TAG-rich lipoproteins assembly and(More)
Clinical studies have indicated that circulating bile acid (BA) concentrations increase following bariatric surgery, especially following malabsorptive procedures such as Roux-en-Y gastric bypasses (RYGB). Moreover, total circulating BA concentrations in patients following RYGB are positively correlated with serum glucagon-like peptide-1 concentrations and(More)
BACKGROUND Resistin is an adipokine, which displays proinflammatory properties. Thus, it is likely that resistin can influence the course of chronic pancreatitis, and/or that chronic pancreatitis may affect the serum resistin concentration. GOALS The aim of the present study was to determine the serum resistin concentration in patients with chronic(More)
Heavy metals (HM) and polycyclic aromatic hydrocarbons (PAHs) are present in the freshwater environment at concentrations that can be hazardous to the biota. Among HMs and PAHs, cadmium (Cd) and anthracene (ANT) are the most prevalent and toxic ones. The response of Chlamydomonas cells to Cd and ANT at concentrations that markedly reduced the growth of(More)
NK cells are a component of innate immunity which activity significantly correlates with health status. The aim of our study was to estimate a status of NK (natural killer) cells in the very old (mean age 92+/-2 ys) and old subjects (mean age 78+/-5 ys) as compared to a control group of young individuals (mean age 25+/-4 ys). NK cells were characterized by(More)
Telomerase is extensively investigated as potential diagnostic and prognostic marker in human tumors. In this study, we determined telomerase activity in histological specimens and voided urine of 52 human bladder cancers. Using the PCR-ELISA method telomerase activity was found in 21 (88%) of the 24 tumor tissues and in the corresponding sediments from(More)
The present study aimed to evaluate the possible relationship between the changes in hydrogen peroxide (H2O2) and nitric oxide (NO) content and the course of growth and reproductive processes of the cell cycle of Chlamydomonas reinhardtii. The peak of H2O2 observed at the beginning of the cell cycle was found to originate from Fe-SOD and Mn-SODchl. activity(More)
