Angiotensin-II (AII), the dominant effector of the renin-angiotensin system, is involved in the pathogenesis of cardiovascular diseases, such as atherosclerosis. Upregulation of the adhesion molecules VCAM-1, ICAM-1, and E-selectin in endothelial cells by inflammatory cytokines through nuclear factor kappa B (NFkappaB) activation is implicated in formation(More)
Diabetic patients undergo a chronic oxidative stress. This phenomenon is demonstrated by low levels of reduced glutathione (GSH) levels. The NADPH used by glutathione reductase for the reduction of oxidized glutathione (GSSG) to GSH is also used by aldose reductase for the reduction of glucose to sorbitol through the polyol pathway. The competition for(More)
OBJECTIVE To determine ambulatory and home blood pressure means and distributions in relation to clinic blood pressure in a general population. METHODS We obtained a random sample of 2400 subjects stratified by sex and 10 year age groups to be representative of residents aged 25-64 years of the city of Monza. Participation rate was 69% (1651 subjects).(More)
The influence of insulin on renal Na+ excretion is still subject to debate. In order to evaluate the effect of insulin suppression on Na+ excretion, 20 never-treated essential hypertensive men and 8 normotensive men were studied. All subjects had a body mass index < 27 kg/m2. Both the glucose and the lipid metabolisms were normal. After 2 weeks under normal(More)
The effect of postural changes on plasma atrial natriuretic factor (ANF) levels was investigated in 16 diabetic hypertensives (eight with and eight without mild autonomic neuropathy) and in 10 hypertensives. The presence of renal damage or secondary hypertension was excluded. All diabetic patients were in good metabolic control. In upright position, the(More)
Ambulatory blood pressure monitoring (ABPM) is increasingly used in the clinical evaluation of hypertension. However, a number of limitations restrict its routine use. One of the limitations is a lack of definite conclusions about ambulatory blood pressure normality, because of the shortcomings of previous studies on this issue. In the present study we(More)
The mammalian kidney is derived from progenitor cells in intermediate mesoderm. During embryogenesis, progenitor cells expressing the Wilms tumor suppressor gene, WT1, are induced to differentiate in response to WNT signals from the ureteric bud. In hereditary Wilms tumors, clonal loss of WT1 precludes the β-catenin pathway response and leads to(More)
It has been suggested that kallikrein-kinin system may influence carbohydrate metabolism via a kinin-mediated increment of insulin-mediated glucose uptake. To evaluate the effect of acute inhibition of the kallikrein-kinin system on insulin sensitivity, a randomized, placebo-controlled, double-blind study was performed in 15 male non-insulin-dependent(More)
The results of the present analysis indicate, from 1969 to 1987, a sharp and stable decline in cardiovascular (CVD) mortality in Italians aged 35-74 years (37.6% in males 53.6% in females). These trends were responsible for consistent reductions of total mortality (27.5% and 38% in the two gender groups, respectively), and for the increase of life(More)
