BACKGROUND High levels of ketone bodies are associated with improved survival as observed with regular exercise, caloric restriction, and-most recently-treatment with sodium-glucose linked transporter 2 inhibitor antidiabetic drugs. In heart failure, indices of ketone body metabolism are upregulated, which may improve energy efficiency and increase blood flow in skeletal muscle and the kidneys....
اخیرا یک سری تحقیقات دامنه داری در زمینه ی تاثیرات پیچیدگی فعلیت محور(task complexity) بر روی تولید کلامی در قالب "صحت"ء "روانی" و "پیچیدگی" گفتار صورت گرفته است. هر چند تاثیرات "پیچیدگی فعلیت محور" برتعامل کلامی و "واکنش فراگیربه بازخورد تصحیح گر"(learner uptake) به ندرت مورد تحقیق قرار گرفته است. به منظور بررسی تاثیرات فعلیت محور بر روی واکنش فراگیر به بازخورد تصحیح گر 38زبان آموز مذکر در سطح...
In obesity, the development of cardiomyopathy is associated with the accumulation of myocardial triacylglycerols (TAGs), possibly stemming from elevation of myocardial long-chain fatty acid (LCFA) uptake. Because LCFA uptake is regulated by insulin and contractions, we examined in cardiac myocytes from lean and obese Zucker rats the effects of insulin and the contraction-mimetic agent oligomyci...
Uteroplacental insufficiency causes intrauterine growth retardation (IUGR) and subsequent low birth weight, which predisposes the affected newborn towards adult Syndrome X. Individuals with Syndrome X suffer increased morbidity from adult ischemic heart disease. Myocardial ischemia initiates a defensive increase in cardiac glucose metabolism, and individuals with Syndrome X demonstrate reduced ...
INTRODUCTION Delayed-enhancement magnetic resonance imaging (DE-MRI) has been recently proposed as an alternative tool in identifying myocardial viability and transmural distribution of necrosis in the myocardium. CASE PRESENTATION We describe a case of a 71-year-old man admitted for ischemic-like chest pain in which DE-MRI and post-nitrate 99mTc-tetrofosmin myocardial scintigraphy equally co...
objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...
