The effect of factor XIII on endothelial barrier function was studied in a model of cultured monolayers of porcine aortic endothelial cells and saline-perfused rat hearts. The thrombin-activated plasma factor XIII (1 U/ml) reduced albumin permeability of endothelial monolayers within 20 min by 30 +/- 7% (basal value of 5.9 +/- 0.4 x 10(-6) cm/s), whereas(More)
Stress evaluation was carried out in 26 patients approximately 7 months after aortic valve replacement with Björk-Shiley valves (13 patients) and St. Jude medical valves (13 patients). During isoproterenol infusion (0.3 micrograms/kg/min), cardiac output increased by a factor of 1.5 and aortic valve area decreased by 50% for both valve groups, while(More)
SUMMARY Stress evaluation was carried out in 26 patients approximately 7 months after aortic valve replacement with Bjork-Shiley valves (13 patients) and St. Jude medical valves (13 patients). During isoproterenol infusion (0.3 gg/kg/min), cardiac output increased by a factor of 1.5 and aortic valve area decreased by 50% for both valve groups, while(More)
Objective: In arteriosclerosis and bypass graft stenosis, intimal proliferation is controlled by local and systemic growth factors, such as platelet derived growth factor (PDGF) or insulin. Intimal hyperplasia can be produced in organ culture models. Our aim was to compare neointima formation in two organ culture models of internal mammary artery (IMA) and(More)
BACKGROUND There are conflicting results on the relationship of N5,N10-methylenetetrahydrofolate reductase C677T gene variation in coronary artery disease and myocardial infarction. METHODS AND RESULTS We analysed this gene variation in 2453 male Caucasians whose coronary anatomy was defined by coronary angiography. In the total sample, the C677T gene(More)
