BACKGROUND AND PURPOSE Endothelium-derived NO is formed from L-arginine by endothelial NO synthase (eNOS) encoded by the NOS 3 gene on chromosome 7. Because several studies have indicated that NO plays a key role in the development of the atherosclerotic process, we investigated whether common variants in the eNOS gene are associated with an increased risk(More)
RATIONALE Adolescent rodents differ markedly from adults in several neuro-behavioural parameters. Moreover, 'paradoxical' responses to psychostimulants have been reported at this age. OBJECTIVES Thus, we investigated the responses of adolescent (post-natal day, PND, 34 to 43) and adult (PND >60) Sprague-Dawley male rats to the psychostimulant drug(More)
To investigate the effects of salt loading on cardiopulmonary and arterial baroreceptor reflexes, 34 hypertensive patients underwent two 4-day periods with different dietary sodium intakes (70 and 370 meq/day). The patients were classified as salt-sensitive or salt-resistant depending on whether the mean arterial pressure value obtained on day 4 of high(More)
BACKGROUND p53 is a transcription factor with tumour suppressor properties, which is able to induce mitochondrial apoptosis independently of its transcriptional activity. We recently synthesised two new compounds (ISA27 and SM13), which block p53-MDM2 interaction and induce apoptosis in p53 wild-type (WT) tumour cells. The aim of this study was to verify(More)
To investigate whether or not hypertension with left ventricular hypertrophy (LVH) modifies the mechanisms underlying the vascular adjustments to orthostatic stress, we evaluated the hemodynamic and hormonal effects of graded lower-body negative pressure (LBNP) (-10 and -40 mm Hg) before and after sympathetic blockade in 10 hypertensive patients with LVH(More)
To investigate the potential contribution of cardiopulmonary reflexes in myocardial ischemia, the coronary vascular response to cardiopulmonary baroreceptor unloading and the number and the duration of spontaneous episodes of symptomatic and asymptomatic myocardial ischemia were evaluated in 23 patients with coronary heart disease. Lower-body negative(More)
Autonomic nervous system dysfunction is part of the spinocerebellar ataxia (SCA) clinical picture, but few data are available on this topic. The present study is aimed to report a detailed investigation of autonomic nervous system in patients with molecular diagnosis of SCA type 2, one of the most frequent forms and the commonest in Italy. Nine patients(More)
