Barrett's esophagus is the transformation of normal esophageal squamous epithelium to specialized intestinal metaplasia (SIM). Among the Barrett's specialized cells, those that can develop protective mechanisms against apoptosis may have potential to become malignant. Studies have shown that overexpression of metallothionein (MT), low molecular protein that(More)
OBJECTIVE Adaptative optic is a new non-invasive imaging technique that allows to measure arterioles wall thickness and diameter with a resolution near two microns. Our objectives were to evaluate the feasibility and the reproducibility of this technique in untreated hypertensive patients. DESIGN AND METHODS In 23 naive hypertensive patients and in 14(More)
Inflammation and neovascularization in vulnerable atherosclerotic plaques are key features for severe clinical events. Dynamic contrast-enhanced (DCE) MRI and FDG PET are two noninvasive imaging techniques capable of quantifying plaque neovascularization and inflammatory infiltrate, respectively. However, their mutual role in defining plaque vulnerability(More)
OBJECTIVE Arachidonate 5-lipoxygenase (5-LO) is a key enzyme in the synthesis of leukotrienes. VIA-2291 is a potent 5-LO inhibitor, which has been shown to reduce hsCRP and noncalcified coronary plaque volume following an acute coronary syndrome (ACS). We aim to evaluate the effect of VIA-2291 on vascular inflammation compared to placebo using FDG-PET. (More)
18F-FDG PET is a new noninvasive tool for inflammation functional imaging. Low spatial resolution is now compensated by coregistration with CT or MRI. New mechanistic insights have emerged from animal and histology to explain the obtained signals by hypoxia, macrophage infiltration, and differentiation. Mixed results have been found in biomarkers studies.(More)
We evaluated the therapeutic effect of L-5-hydroxytryptophan (L-5HTP), the precursor of serotonin (5-hydroxytryptamine), combined with carbidopa, a peripheral decarboxylase inhibitor, in patients with intention myoclonus and examined the serotonin metabolites in spinal fluid, blood and urine before and during therapy. In 18 patients with intention myoclonus(More)
OBJECTIVE To evaluate in hypertensive patients followed in a specialized hypertension unit, the prevalence of subjects uncontrolled despite triple therapy including a diuretic. The aim is to estimate the percentage of hypertensive patients with an indication to renal denervation. METHOD From a database of computerized medical records of a unit specialized(More)
PURPOSE OF REVIEW A healthy diet should be rich in vegetables and fruits, whole-grain, high-fiber foods, and fish and should contain a small amount of saturated and trans fats. In addition to these recommendations, some food ingredients such as plant sterol/stanol soy protein and isoflavones may help reduce cholesterol levels. Increased dietary fiber(More)
The High Level Architecture (HLA) for distributed simulations was proposed by the Defense Modeling and Simulation Office of the Department of Defense (DOD) in order to support interoperability among simulations as well as reuse of simulation models. One aspect of reusability is the ability to collect and analyze data from simulation executions, including a(More)
INTRODUCTION Bromocriptin, member of the class of ergolines, is commonly prescribed as treatment of Parkinson's disease. Apart from vascular, digestif, neurologic and psychic disorders, the authors report cases of retroperitoneal fibrosis and pleural effusion, as adverse reactions related to the bromocriptin. SYNTHESIS About 40 cases of skin, pleural,(More)
