AIMS This study investigated whether sedentary behaviour and different activity levels have an independent association with carotid intima-media thickness (IMT) and with the 3-year IMT progression in different carotid segments. METHODS AND RESULTS The study population included 614 healthy men and women (mean age = 44 +/- 8 years) without carotid(More)
OBJECTIVE This study evaluated the impact of prolonged circulatory unloading and subsequent left ventricular (LV) mass decrease on LV myocardial performance. Five-week head-down tilt (-6°) bed rest (HDTBR) was used as a model of prolonged circulatory unloading. METHODS Ten young healthy male volunteers (age 23 ± 2 years) were studied a day before and(More)
Physical activity (PA) may modify cardiovascular structure and function as well as insulin sensitivity and level of plasma adipokines in relation to its extent, duration, and intensity. To evaluate the associations of average daily PA and bouts of moderate-to-vigorous-intensity PA with cardiovascular and metabolic measures, 45 healthy volunteers (mean age =(More)
During 1994, 19 thyroid tumor-affected children and 17 healthy children from the Gomel region, one of the areas most polluted by the Chernobyl fallout, were analysed for (i) the presence of in their urine and (ii) chromosome aberrations (CA) in circulating lymphocytes. They were compared with 35 healthy children from Pisa, Italy. Tumor-affected children(More)
BACKGROUND Arterial hypertension is frequently associated with the presence of structural alterations in small arteries. Moreover, a reduced coronary flow reserve and vasodilator capacity has been observed in essential hypertensive patients, possibly due, at least in part, to microangiopathy of small coronary vessels. The aim of the present study was to(More)
CONTEXT Adiponectin inhibits protein synthesis in cardiac myocytes, thereby opposing the effect of cardiac workload and trophic factors (in particular, insulin) on left ventricular (LV) mass and wall thickness (WT). OBJECTIVE We tested whether adiponectin and its isoforms are related to LV mass, WT, and function independently of metabolic factors. (More)
BACKGROUND Carotid intima-media thickness (IMT), indices of large artery stiffness and measures of endothelium function may be used as markers of early atherosclerosis in type 1 diabetes mellitus (T1DM). The aim of the present study was to compare the indices of large artery structure and function as well as endothelial function and regenerating capacity(More)
BACKGROUND AND PURPOSE Three-dimensional (3-D) vascular ultrasound can be expected to improve qualitative evaluation of vessel pathology and to provide quantitative data on vascular morphology and function. The objective of this study was to develop an ultrafast 3-D vascular system and to validate its performance for quantitation of atherosclerosis and(More)
BACKGROUND Increased central aortic pressure resulting from large artery stiffening and increased wave reflection is associated with higher hypertension-related morbidity. OBJECTIVE The goal of this study was to evaluate the effects of a vasodilator-based therapy with the calcium channel blocker barnidipine on arterial stiffness, wave reflection, and left(More)
Sedentary aging is associated with endothelial dysfunction and nitric oxide (NO) impairment. The aim of the present study was to assess the effects of regular physical exercise on nitrite/nitrate (NOx) concentrations and microcirculatory function in older men compared with young individuals. We measured NOx plasma concentrations and baseline and stimulated(More)
