BACKGROUND The significance of heavy metals in pathogenesis of the circulatory system diseases remains unresolved. The aim of the study was to evaluate electrocardiographic changes in workers occupationally exposed to lead without clinical presentation of cardiac involvement. METHODS A group of 60 smelters and refiners and 45 healthy men, as a control(More)
BACKGROUND In patients with systemic scleroderma (SSc), clinically evident cardiac involvement is recognized to be a poor prognostic factor. The aim of the study was to evaluate electrocardiographic changes, parameters of heart rate variability (HRV), and heart rate turbulence (HRT) in patients with SSc without evident symptoms of heart disease. METHODS A(More)
Aim of the study was to assess the effect of KT on heart conduction in HD children. Non-invasive electrocardiographic method of BSPM was used. Isochrone maps, presenting a VAT distribution, were taken from eight HD patients and 26 normal subjects. Patients were divided into two groups: I--three children were HD <12 months prior to KT; II--five children were(More)
BACKGROUND Cardiovascular complications are considered a significant problem in patients with chronic kidney disease (CKD). Body surface potential mapping (BSPM) is a noninvasive method that is useful in detecting early changes involving the heart. The aim of the study was to evaluate possible abnormalities within the cardiac intraventricular conduction(More)
The aim of the study was to examine endothelial function in workers occupationally exposed to lead by means of FMD (flow-mediated dilatation). 44 men professionally exposed to lead, smelters and refiners, employees working at copper smelter and control group of 41 healthy men were enrolled into the study. Within the group of men occupationally exposed to(More)
The authors examined the number of interstitial cells of Cajal-like cells (ICC-LCs) in obstructed ureteropelvic junction (UPJ) in comparison with normal UPJ specimens and age-related changes. A total of 20 human formalin fixed, paraffin-embedded specimens of intrinsic UPJO from children at the mean age of 8.1 years (age range: 8 months–16.8 years) and 5(More)
OBJECTIVES The most important factors in the pathogenesis of cognitive disorders in diabetes mellitus (DM) are metabolic changes directly caused by hyperglycemia. Impairment of cognitive function is accompanied by a decrease in cerebral insulin. Insulin improves cognitive processes, including somatosensoric cognitive functions. Cognitive disorders are(More)
It is possible that electromagnetic field (EMF) generated by mobile phones (MP) may have an influence on the autonomic nervous system (ANS) and modulates the function of circulatory system. The aim of the study was to estimate the influence of the call with a mobile phone on heart rate variability (HRV) in young healthy people. The time and frequency domain(More)
AIM The aim of the study is an analysis of distribution of visual evoked potentials (VEP) latencies in the group of schizophrenic and healthy subjects. METHOD A study was carried out on a group of 30 patients (8 males and 22 females) with a DSM-III-R diagnosis of schizophrenia (disorganised schizophrenia--5, paranoid schizophrenia--12, residual(More)
Sirtuins, silent information regulator 2 (Sir 2) proteins, belong to the family of NAD+-dependent enzymes with deacetylase or mono-ADP-ribosyltransferase activity. These enzymes are responsible for processes of DNA repair or recombination, chromosomal stability and gene transcription. In mammals, sirtuins occur in seven varieties, from 1 to 7 (SIRT1–SIRT7),(More)
