Flavanols from chocolate appear to increase nitric oxide bioavailability, protect vascular endothelium, and decrease cardiovascular disease (CVD) risk factors. We sought to test the effect of flavanol-rich dark chocolate (FRDC) on endothelial function, insulin sensitivity, beta-cell function, and blood pressure (BP) in hypertensive patients with impaired(More)
Background: Recent evidence has indicated that flavanol consumption may have many health benefits in humans, including improved cognitive activities. Objective: The aim was to evaluate the effect of flavanol consumption on cognitive performance in cognitively intact elderly subjects. Design: This was a double-blind, controlled, parallel-arm study conducted(More)
Oxidative stress results from an imbalance between excessive formation of reactive oxygen species (ROS) and/or reactive nitrogen species and limited antioxidant defences. Endothelium and nitric oxide (NO) are key regulators of vascular health. NO bioavailability is modulated by ROS that degrade NO, uncouple NO synthase, and inhibit synthesis. Cardiovascular(More)
It has been suggested that cerebrovascular factors contribute to Alzheimer's disease. Soluble CD40 ligand (sCD40L) is directly involved in the development of vascular damage. We tested the hypothesis that sCD40L may be enhanced in Alzheimer's disease and predictive of its clinical course. Plasma sCD40L levels were evaluated in three groups of 40 consecutive(More)
Hyperuricemia is commonly associated with traditional risk factors such as dysglicemia, dyslipidemia, central obesity and abnormal blood pressure, i.e. the metabolic syndrome. Concordantly, recent studies have revived the controversy over the role of circulating uric acid, hyperuricemia, and gout as an independent prognostic factor for cardiovascular(More)
Angiotensin converting enzyme inhibitors (ACE-I) are able to reduce the formation of the potent vasoconstrictor endothelin-1 and increase nitric oxide bioavailability in human vascular endothelial cells (HUVECs). We tested the effects of two sulfhydryl-containing ACE-I, zofenoprilat, and captopril, and two nonsulfhydryl containing ACE-I, enalaprilat and(More)
OBJECTIVES Long and repeated periods of sustained wakefulness constitute a serious problem for shift workers in general and for medical interns in particular. In a real clinical setting, we investigated whether taking a long nap can counteract the negative consequences of acute sleep deprivation on executive skills in residents. METHODS Fifty-four interns(More)
Hypertension and arterial stiffening are independent predictors of cardiovascular mortality. Flavonoids may exert some vascular protection. We investigated the effects of black tea on blood pressure (BP) and wave reflections before and after fat load in hypertensives. According to a randomized, double-blind, controlled, cross-over design, 19 patients were(More)
Background. Cerebral amyloid angiopathy-related inflammation (CAA-ri) results from autoimmune response to beta-amyloid deposits in cerebral vessels. Its clinical course and complications have seldom been described in literature. Case Report. In a patient presenting with delirium and left hemiparesis the diagnosis of CAA-ri was supported by the finding of(More)
Anthracyclines (A) and taxanes (T) are standard first-line chemotherapy agents for patients with advanced breast cancer. Platinum analogues have also shown activity in the triple-negative breast cancer (TNBC) histology, but clinical data are limited. Here we report the long-term follow-up of a phase II study on TNBC treated with a combined modality therapy,(More)
