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...

BACKGROUND Although defects on intracoronary myocardial contrast echocardiography (MCE) indicate loss of viability after reperfusion, opacified segments may also exhibit persistent dyssynergy. Therefore, we related the intensity and texture of opacification produced by an intravenous contrast agent to histological findings to determine the characteristics of necrotic tissue by postreperfusion M...

OBJECTIVES The purpose of the present work was to investigate the effect of marine crustacean extract (MCE) from marine mantis shrimp Erugosquilla massavensis and silymarin on oxidative stress induced by carbon tetrachloride (CCl4) in rat liver and erythrocytes. MATERIALS AND METHODS Male rats were randomly divided into 3 main groups, (1) control group which administered olive oil orally for ...

Microchip electrophoresis (MCE) has been recognized as an important separation technique on the research field of micro total analytical systems (μ-TAS) since the first publication on MCE was reported by Manz et al. in 1992 [1]. In MCE, there are several advantages, e.g., high speed analysis in seconds, small amount of sample, high separation efficiency, and high-throughput analysis by using mi...

Purpose: Low-dose dobutamine echocardiography (LDDE) has been demonstrated as an accurate imaging modality to identify viability after acute myocardial infarction (AMI), but LDDE has its limitations. Myocardial contrast echocardiography (MCE) is a good tool to assess microvascular perfusion. This study was undertaken to compare the effect of real-time MCE and LDDE in early assessment of left ve...

OBJECTIVES The purpose of this study was to compare myocardial contrast echocardiography (MCE) with single-photon emission computed tomography (SPECT) for the detection of significant coronary artery disease (CAD) in patients with symptoms suggestive of CAD. BACKGROUND Single-photon emission computed tomography is a well-established method of assessing patients with CAD. Myocardial contrast e...

BACKGROUND Colonoscopy visualizes more of the colon than flexible sigmoidoscopy. This study compares the outcomes of an unsedated modified colon endoscopy (MCE) with flexible sigmoidoscopy (FS) in family medicine practice. METHODS We conducted a retrospective chart review of existing clinical data to compare outcomes for 48 patients undergoing MCE and 35 patients undergoing FS at 3 family med...

Hormonal induction of growth-arrested 3T3-L1 preadipocytes triggers a signaling cascade that culminates in adipogenesis. CCAATenhancer-binding protein (CEBP)beta is expressed immediately but gains DNA-binding activity only after a long lag as the cells synchronously begin mitotic clonal expansion (MCE). After MCE, a process required for adipogenesis, CEBPbeta activates expression of CEBPalpha a...

Background. Since myocardial blood flow changes dynamically after reperfusion and since both hyperemia and impairment in microvascular function exist within the acutely reperfused bed, we sought to investigate the role of myocardial contrast echocardiography (MCE) in (1) defining the temporal variability in perfusion patterns after reflow and relating these to microsphere-derived blood flow; (2...
