The Adenosine Hypothesis Revisited: Modulation of Coupling between Myocardial Perfusion and Arterial Compliance
For over four decades the thoracic aortic ring model has become one of the most widely used methods to study vascular reactivity and electromechanical coupling. A question that is rarely asked, however, is what function does a drug-mediated relaxation (or contraction) in this model serve in the intact system? The physiological significance of adenosine relaxation in rings isolated from large el...
متن کاملAssessment of segmental myocardial blood flow and myocardial perfusion reserve by adenosine-stress myocardial arterial spin labeling perfusion imaging.
PURPOSE To determine the feasibility of measuring increases in myocardial blood flow (MBF) and myocardial perfusion reserve (MPR) on a per-segment basis using arterial spin labeled (ASL) magnetic resonance imaging (MRI) with adenosine vasodilator stress in normal human myocardium. MATERIALS AND METHODS Myocardial ASL scans at rest and during adenosine infusion were incorporated into a routine...

on translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولRelationship between Baseline ECG Abnormalities and Quantitative Perfusion Parameters of Myocardial Perfusion Findings
Background: Coronary Artery Disease (CAD) is one of the major causes of mortality in most countries. Electrocardiography (ECG) and myocardial perfusion imaging (MPI) are non-invasive disgnostic tests for CAD. Finding a relationship between abnormal findings in the baseline ECG and MPI findings can be helpful in better diagnosis of CAD. Materials and Methods: The present study examined ECG of pa...
