OBJECTIVE To assess the ischemic threshold and stress-induced left ventricular dysfunction after high fat (HFM) and high carbohydrate (HCM) meals in patients with stable coronary disease. METHODS Twelve patients (68 ± 7 years) underwent stress (treadmill exercise testing) echocardiography after fasting (8h), after HFM and HCM (2h). Time to 1mm ST-segment(More)
BACKGROUND The aim of this study was to evaluate feasibility and accuracy of a videophone-based system for remote cardiopulmonary examination of patients with heart failure. METHODS AND RESULTS Fifty patients were examined by 2 cardiologists, 1 with a conventional stethoscope and 1 remotely with a videophone-based method, employing an electronic(More)
The effect of prenatal ethanol exposure on N-methyl-D-aspartate (NMDA)-sensitive [3H]-glutamate receptor binding site density was studied in rat brain. Pregnant Sprague-Dawley rats were fed a liquid diet containing 3.35% ethanol throughout gestation. This diet produced maternal peak blood ethanol levels of about 39 mg/dl eight hours after the administration(More)
The effect of prenatal ethanol exposure on putative glutamate receptor binding sites in rat brain was studied using radiohistochemical techniques. Pregnant Sprague-Dawley rats were fed a liquid diet containing either 3% or 6% (vol./vol.) ethanol throughout gestation. Pair-fed dams received isocalorically matched liquid diets and a lab chow ad lib group(More)
BACKGROUND Previous studies provide evidence for a significant reduction of coronary flow reserve after ingestion of meals of different compositions. A possible role of hyperinsulinemia and increased free fatty acid levels, which are deleterious during acute myocardial ischemia and reperfusion, has been hypothesized. We assessed in patients with stable(More)
The effect of prenatal ethanol exposure on the kainate-sensitive subtype of glutamate receptor binding sites was studied using in vitro 3H-vinylidene kainic acid (VKA) autoradiography. Pregnant Sprague-Dawley rats were fed a liquid diet containing either 3.35% or 6.7% ethanol throughout gestation. Pair-fed dams received isocalorically matched liquid diets(More)
The long-term consequences of prenatal ethanol exposure on histochemically detectable hippocampal mossy fiber zinc was examined using a recently developed quantitative histofluorescence procedure. Pregnant Sprague-Dawley rats were maintained throughout gestation on one of three dietary regimens: (a) a liquid diet containing either 3.35% ethanol, (b) an(More)
The possibility of modifying cardiac metabolism by switching the fuel used by the myocardium could become increasingly important. Inhibitors of free fatty acid (FFA) oxidation could have an important role in therapeutic strategy for patients with heart failure, and shifting the energy substrate preference away from FFA metabolism and toward glucose(More)
BACKGROUND Capsaicin has been shown to exert direct vasodilating effects through increased calcitonin gene-related peptide (CGRP) release. However, no data exist on its effect following systemic administration in humans. METHODS Twelve male patients with stable coronary disease and a persistently positive exercise were selected for study. According to a(More)
The effect of perinatal hypothyroidism on hippocampal mossy fiber zinc density was examined in rats. Timed pregnant Sprague-Dawley rat dams were given water containing either 0.02% propylthiouracil (PTU) or vehicle from gestational day 18 until their litters were weaned on postnatal day 31. Hippocampal mossy fiber zinc density was reduced by 75% in both the(More)
