OBJECTIVE To investigate the relationship between endothelium-dependent and endothelium-independent functions and the stiffness of conduit arteries as well as levels of endothelial activation markers in patients with systemic sclerosis (SSc). METHODS Endothelium-dependent (i.e., flow-mediated) and endothelium-independent (i.e., nitroglycerin-induced)(More)
OBJECTIVE Atherosclerotic progression is accelerated in rheumatoid arthritis (RA). We evaluated arterial stiffness and endothelial dysfunction in RA patients and controls by pulse wave analysis (PWA). METHODS Thirty RA patients with long-standing disease and 30 age- and sex-matched controls were examined using applanation tonometry of the radial artery(More)
Growth hormone (GH) deficiency is associated with abnormal vascular reactivity and development of atherosclerosis. GH treatment in GH deficient states restores systemic vascular resistance, arterial compliance, endothelium-dependent and endothelium-independent vasodilation, and may reverse markers of early atherosclerosis. However, very little is known(More)
Acromegaly [overproduction of GH (growth hormone)] is associated with cardiovascular disease. Transgenic mice overexpressing bGH (bovine GH) develop hypertension and hypercholesterolaemia and could be a model for cardiovascular disease in acromegaly. The aims of the present study were to investigate the effects of excess GH on vascular function and to test(More)
OBJECTIVE We have established a technique to estimate the total rate of nitric oxide (NO) formation in mice, based on inhalation of a stable oxygen isotope (18O(2)). Changes of NO production with age were also studied. METHODS The experiments were performed in eight-week- (n=6) and eight-month-old (n=6-7), respectively, female (C57/Bl6xCBAca) mice. Pairs(More)
BACKGROUND Nitric oxide (NO) is predominantly a locally acting mediator, affecting several functions in the human female reproductive tract. In vivo, it is quickly metabolized to its stable end product nitrate, which is cleared by the kidney. METHODS AND RESULTS The aim of the present study was to evaluate possible fluctuations of plasma nitrate(More)
OBJECTIVE Low adipocyte IRS-1 protein expression is a biomarker for insulin resistance and early atherosclerosis. However, whether IRS-1 protein expression is related to systemic arterial stiffness, is unknown. METHODS AND RESULTS Ten non-diabetic male subjects with low adipocyte IRS-1 protein expression (LIRS) were matched with 10 non-diabetic males with(More)
BACKGROUND The aim of the study was to evaluate the acute and continuous (up to 14 days of treatment) effect of growth hormone (GH) on blood pressure (BP) regulation and to investigate the interplay between GH, nitric oxide (NO) and BP. In un-supplemented and GH supplemented hypophysectomized (Hx) male rats as well as intact rats, continuous resting mean(More)
