In this study, we tested the hypothesis that myocardial ischemia induced by exercise in patients is associated with diminished metabolism and/or delayed clearance of an intravenously injected fatty acid, iodine 123-labeled phenylpentadecanoic acid (IPPA). Fifteen normal volunteers and 18 patients with significant coronary heart disease (CHD) received IPPA during exercise. In the patients with C...
BACKGROUND The reproducibility of brachial artery flow-mediated vasodilatation (FMD) is limited by the operator dependence of most measurement methods. METHODS A new automated computerized analysis of brachial artery ultrasound scan providing a continuous evolution of the diameter during acute hyperemia, reactive to short hyperemia of the forearm and hand, was tested in 10 normal volunteers a...
Objective(s): Crocin is the chemical ingredient primarily responsible for the color of saffron. It has different pharmacological effects such as antioxidant, anticancer and memory improving activities. Crocin tablets were evaluated for short-term safety and tolerability in healthy adult volunteers. Materials and Methods: The study was a randomized, double-blind, placebo-controlled design consis...
BACKGROUND Xylitol is a 5-carbon sugar that can lower the airway surface salt concentration, thus enhancing innate immunity. We tested the safety and tolerability of aerosolized iso-osmotic xylitol in mice and human volunteers. METHODS This was a prospective cohort study of C57Bl/6 mice in an animal laboratory and healthy human volunteers at the clinical research center of a university hospit...
Background: Depression is a common problem and reduces function of persons. Evaluation of this matter in Gifted Intelligence– because superior their beneficial ness– have more importance. Our aim in this study is to determine relative frequency of depression in Gifted Intelligence as compared with Normal persons. Materials and Methods: In the context of a case – control study 90 Normal volunt...
Iodine deficiency remains a major health problem in the world, including some parts of Iran. It has been recognized that there is usually a close and inverse relationship between iodine in the soil and water and presence of endemic goiter. Calcium has been suggested as one of goitrogens, though the definite role, extent and mechanism particularly in human have not been studied. Serum protein-...
Introduction Quantitative myocardial perfusion to assess impaired coronary vasoreactivity has been used to identify subclinical atherosclerosis. Impaired coronary vasodilation has been observed in patients with cardiac risk factors in the MESA cohort. The coronary vasodilator response in patients with angiographically normal coronary arteries/ minimal stenosis is not known. The purpose of this ...
