Purpose Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods We re...

Objective—To determine whether myocardial contrast echocardiography (MCE) following intravenous injection of perfluorocarbon microbubbles permits identification of resting myocardial perfusion abnormalities in patients who have had a previous myocardial infarction. Patients and interventions—22 patients (mean (SD) age 66 (11) years) underwent MCE after intravenous injection of NC100100, a novel...

BACKGROUND There are currently no data on the accuracy of intravenous myocardial contrast echocardiography (MCE) in detecting myocardial hibernation in man and its comparative accuracy to dobutamine echocardiography (DE) or thallium 201 (Tl(201)) scintigraphy. METHODS AND RESULTS Twenty patients with coronary artery disease and ventricular dysfunction underwent MCE 1 to 5 days before bypass s...

We have developed a novel loss function that embeds largemargin classification into Minimum Classification Error (MCE) training. Unlike previous efforts this approach employs a loss function that is bounded, does not require incremental adjustment of the margin or prior MCE training. It extends the Bayes risk formulation of MCE using Parzen Window estimation to incorporate large– margin classif...

Background: Little is known about the relation between the extent of microvascular damage and infarct size in patients after successful mechanical reperfusion of acute myocardial infarction. Objective: To compare the spatial extent of reduced myocardial signal between real time myocardial contrast echocardiography (MCE) and single photon emission computed tomography (SPECT) after successful mec...

Moutan Cortex (MCE) has been used in traditional medicine to remove heat from the blood, promote blood circulation and alleviate blood stasis. This study was conducted to evaluate the effects of MCE on regulatory mechanisms of cytokines and nitric oxide (NO) involved in immunological activity of Raw264.7 cells. Cells were pretreated with methanolic extracts of MCE, and further cultured for an a...

A memory conjunction error (MCE) is said to occur when a novel test item composed of parts of previously studied items is falsely recognized as old. This study investigated the effects of warning against false positives and the semantic relatedness between study and test items on the magnitude of the MCE. Results indicate that while the MCE depends critically on the semantic relatedness, warnin...

MCE has evolved from a laboratory tool to a clinical procedure. It would be wrong to consider it merely another tool for imaging of myocardial perfusion. As discussed, it allows physicians to bring physiology and pathophysiology to the bedside, providing a better understanding of the underlying mechanisms of abnormal findings in individual patients. MCE can provide quantitative measurements tha...

BACKGROUND Although assessment of myocardial perfusion by myocardial contrast echocardiography (MCE) is feasible, its incremental benefit to stress echocardiography is not well defined. We examined whether the addition of MCE to combined dipyridamole-exercise echocardiography (DExE) provides incremental benefit for evaluation of coronary artery disease (CAD). METHODS AND RESULTS MCE was combi...
