AIM The aim of our cross-sectional study was to assess the relationships between body iron stores, oxidative stress, impaired insulin sensitivity and carotid atherosclerosis in a cohort of healthy men in primary prevention of cardiovascular disease. METHODS We examined 151 volunteers, aged 35- 60 years. Anthropometric parameters, markers of metabolic(More)
AIMS The aim of our study was to compare the influence of a hypocaloric, high-fat diet enriched with MUFA (M) and conventional diet (C) on weight loss and metabolic parameters in obese non-diabetic and obese Type 2 diabetic subjects over a 3-month period. It was our hypothesis that the enriched diet would be more effective in decreasing blood glucose and(More)
Atherogenic lipoproteins can cause endothelial dysfunction in the initial stage of atherogenesis. In our study we examined 134 patients with defined hyperlipoproteinemia (non-HDL cholesterol>4.1 mmol/l or triglycerides>2.5 mmol/l or taking any of lipid lowering drugs)--94 men and 40 women. The subgroup of controls of comparable age contained 54(More)
BACKGROUND The aim of our study was to assess the impact of increased iron stores on the presence of asymptomatic atherosclerosis in a cohort of healthy men. We anticipated that higher iron stores would be associated with higher soluble cluster of differentiation 163 (sCD163) concentrations, elevated markers of oxidative stress, inflammation and higher(More)
BACKGROUND/OBJECTIVES Vegans have a lower incidence of insulin resistance (IR)-associated diseases and a higher insulin sensitivity (IS) compared with omnivores. The aim of this study was to examine whether the higher IS in vegans relates to markers of mitochondrial biogenesis and to intramyocellular lipid (IMCL) content. SUBJECTS/METHODS Eleven vegans(More)
Our aim was to detect markers of Chlamydia pneumoniae (CPN) and human cytomegalovirus (HCMV) infection in patients with peripheral vascular occlusive disease and to follow markers of inflammation, endothelial dysfunction and lipid metabolism alteration in patients with active infection. CPN genome was detected in 9 (47.4 %) patients by at least one PCR(More)
BACKGROUND AND AIM In the recent years several studies showed the association between body iron stores, represented by serum ferritin, and atherosclerosis. It was proposed that iron bound to ferritin catalyzes the formation of highly reactive forms of oxygen free radicals which subsequently cause the oxidative modification of atherogenic lipoproteins. Aim(More)
AIM In this study, we tested the impact of short-term intake of increased amounts of C18:1 trans fatty acids (TFAs) on parameters of cellular and humoral immunity in healthy young men. METHODS Twenty-seven healthy young men were subsequently exposed to a standard diet for 7 days and an experimental TFA-enriched diet for 4 days. The mean energy content of(More)
Subcutaneous apomorphine, a dopaminergic agonist, is used as a neuroendocrine probe for assessing central dopaminergic activity. The aim of our study was to test sublingual apomorphine for the same purpose. We administered sublingual apomorphine in a weight-dependent dose (0.033 mg/kg) to 42 healthy men. Prolactin and growth hormone levels were measured(More)
The study investigates the relationship between the labile iron pool (LIP) in circulating monocytes and markers of iron metabolism, inflammation, oxidative stress, endothelial dysfunction and arterial elasticity in patients with chronic cardiovascular disease and in healthy volunteers. The patients with a history of CVEs had significantly higher LIP values(More)
