BACKGROUND Idiopathic hypercalciuria (IH) is defined as hypercalciuria that persists after correction of dietary inbalances and has no detectable causes. Patients with IH have a higher prevalence of osteoporosis. Defective reabsorption of calcium by the renal tubule is considered a likely mechanism of IH. N-acetyl-beta-D-glucosaminidase (NAG) is a lysosomal(More)
Non-enzymatic glycation is a common post-translational modification of tissue and plasma proteins which can impair their functions in living organisms. In this study, the authors have demonstrated for the first time an inhibitory effect of in vitro glycation on the catalytic activity of alanine aminotransferase (ALT, EC 2.6.1.2), a pyridoxal phosphate(More)
The transfer kinetics of cyclosporine across the dually perfused rat placenta in the maternal to fetal direction and a possible involvement of P-glycoprotein were investigated. The transplacental clearance of cyclosporine in the materno-fetal direction was found to be dependent on the maternal inflow concentration of cyclosporine. Coadministration of(More)
Incubation of 50 mM D-glucose with aspartate aminotransferase (AST, EC 2.6.1.1) preparations (purified pig heart enzyme or a rat liver 20,000 x g supernatant) at 25 degrees C had no effect on enzyme activity. 50 mM D-fructose or D-ribose gradually inhibited pig heart AST under the same conditions to zero activity after 14 days. 50 mM DL-glyceraldehyde(More)
Switching of the paraprotein isotype or transient presence of oligoclonal bands detectable by serum immunofixation electrophoresis has been reported following not only transplantations, but also after intensive chemotherapy for leukemia. Retrospective analysis of 72 transplanted myeloma patients was carried out to determine the frequency and clinical(More)
BACKGROUND In vitro hemolysis, the prevailing cause of preanalytical error in routine laboratory diagnostics, might influence the reliability of several tests, affect the quality of the total testing process and jeopardize patient safety. Although laboratory instrumentation is now routinely equipped with systems capable of automatically testing and(More)
OBJECTIVE The aim of this study was to monitor and compare metabolic changes in the skeletal muscle during coronary artery bypass grafting surgery with and without cardiopulmonary bypass (CPB) by means of interstitial microdialysis. Glucose, lactate, pyruvate and glycerol were assessed as markers of basic metabolism and tissue perfusion. METHODS Twenty(More)
AIM Wound and mediastinal infections are still very serious complications of open-heart surgery, in spite of the use of prophylactic antibiotics. The use of cardiopulmonary bypass (CPB) is associated with profound physiological changes affecting the pharmacokinetic behaviour of antibiotics. The aim of this pilot study was to monitor the tissue(More)
The paper presents a prospective cohort study. Observed group was formed of children with plaque psoriasis (n=19) treated by Goeckerman therapy (GT). The study describes adverse (side) effects associated with application of GT (combined exposure of 3% crude coal tar ointment and UV radiation). After GT we found significantly increased markers of oxidative(More)
BACKGROUND Transjugular intrahepatic portosystemic shunts (TIPSs) have become a widely accepted tool in the treatment of patients with symptomatic portal hypertension. The aim of our study was to assess the value of cardiac markers before and after TIPS insertion for the prediction of one-year mortality in cirrhotic patients. METHODS The study population(More)
