a fundamental study of "histiriographic metafiction", and "literary genres", as introduced in "new historical philosophy", and tracing them in the works of julian barnes.
abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
15 صفحه اولSpatial heterogeneity in fasting and insulin-stimulated (18)F-2-deoxyglucose uptake in pigs with hibernating myocardium.
BACKGROUND Previous studies of hibernating myocardium in the fasting state have shown regionally increased (18)F-2-deoxyglucose (FDG) uptake with a marked transmural gradient. We hypothesized that this adaptation to chronic ischemia might be associated with altered maximal FDG uptake. METHODS AND RESULTS Pigs were instrumented with a 1.5-mm proximal left anterior descending artery (LAD) steno...
متن کاملQuantitative analysis of acute myocardial infarct in rat hearts with ischemia-reperfusion using a high-resolution stationary SPECT system.
UNLABELLED The purpose of this study was to develop an in vivo imaging protocol for a high-resolution stationary SPECT system, called FASTSPECT, in a rat heart model of ischemia-reperfusion (IR) and to compare 99mTc-sestamibi imaging and triphenyltetrazolium chloride (TTC) staining for reliability and accuracy in the measurement of myocardial infarcts. METHODS FASTSPECT consists of 24 modular...
متن کاملUtility of 18 F-FDG and 11C-PBR28 microPET for the assessment of rat aortic aneurysm inflammation
BACKGROUND The utility of (18) F-FDG and (11)C-PBR28 to identify aortic wall inflammation associated with abdominal aortic aneurysm (AAA) development was assessed. METHODS Utilizing the porcine pancreatic elastase (PPE) perfusion model, abdominal aortas of male Sprague-Dawley rats were infused with active PPE (APPE, AAA; N = 24) or heat-inactivated PPE (IPPE, controls; N = 16). Aortic diamete...
متن کاملIschemic preconditioning reduces infarct size in swine myocardium.
We evaluated the hypothesis that stunning swine myocardium with brief ischemia reduces oxygen demand in the stunned region and increases tolerance of myocardium to longer periods of ischemia. Wall function was quantified with ultrasonic crystals aligned to measure wall thickening, and stunning was achieved with two cycles of left anterior descending coronary artery (LAD) occlusion (10 minutes) ...
