BACKGROUND Both intermittent triggered and real-time myocardial contrast echocardiography (MCE) have been proposed to detect impaired myocardial perfusion. We compared the ability of these 2 methods to quantify altered myocardial blood flow (MBF) and transmural distribution of MBF produced by graded coronary stenoses. METHODS AND RESULTS In 8 open-chest dogs, we created 4 graded left anterior...

A coronary artery-left ventricular fistula (CAF) is an extremely rare anatomical abnormality in which blood drains directly from a coronary artery into the left ventricle. CAF may cause myocardial ischaemia and angina. Myocardial contrast echocardiography (MCE) is a non-invasive technique which assesses myocardial perfusion. We describe a patient with CAF in whom transmural myocardial ischaemia...

When induced to differentiate, growth-arrested 3T3-L1 preadipocytes synchronously reenter the cell cycle and undergo mitotic clonal expansion (MCE) followed by expression of genes that produce the adipocyte phenotype. The preadipocytes traverse the G(1)S checkpoint synchronously as evidenced by the expressionactivation of cdk2-cyclin-EA, turnover of p27kip1, hyperphosphorylation of Rb, transloc...

Effects of maternal cytoplasmic environment (MCE) on development rate in rainbow trout were evaluated within a quantitative trait loci (QTL) analysis framework. Previous research had identified QTL for development rate in doubled haploid (DH) progeny produced from a cross between the Oregon State University (OSU) and the Swanson (SW) River rainbow trout clonal lines. In this study, progeny for ...

AIMS Myocardial blood flow (MBF) is the gold standard to assess myocardial blood supply and, as recently shown, can be obtained by myocardial contrast echocardiography (MCE). The aims of this human study are (i) to test whether measurements of collateral-derived MBF by MCE are feasible during elective angioplasty and (ii) to validate the concept of pressure-derived collateral-flow assessment. ...

Introduction: ECIGs are currently under scrutiny concerning their safety, particularly in reference to the impact ECIG liquids (E-liquids) have on human health. One concern is that aerosolized E-liquids contain trace metals that could become trapped in respiratory tissues and induce pathology. Methods: To mimic this trapping, peristaltic pumps were used to generate and transport aerosol onto mi...

Objectives. We sought to assess the feasibility and accuracy of myocardial contrast echocardiography (MCE) using standard imaging approaches for the detection of perfusion defects in patients who had a myocardial infarction (MI). Background. Myocardial contrast echocardiography may be more versatile than perfusion scintigraphy for identifying the presence and extent of perfusion defects after M...

the following optimization of the discriminative functions the extended BW algorithm (12) was applied to re-estimate the mixtures of the phoneme models. All phoneme alternatives within the automatically derived phoneme seg-mentation were used in the calculation of the discriminance measure. According to (6), the mixtures of the correct and of all competing models were updated to minimize the ob...

cyanobacteria blooms are common in baltic sea and their intensity have been increased due toanthropogenic eutrophication. in this study we investigated the cyanotoxin levels in the water samplescollected from four different locations in the baltic sea at three different seasons including summer 2011.protein phosphatase 2a (pp2a) inhibition assays, enzyme-linked immunosorbent assays (elisa) and ...

In the setting of suspected acute myocardial infarction (AMI), a cardiologist needs to know three things: (1) whether there is actually an ongoing infarction, (2) whether reperfusion therapy has succeeded, and (3) how much myocardium was salvaged by reperfusion. Myocardial contrast echocardiography (MCE) can answer the first question by demonstrating the presence of a perfusion defect resulting...
