DIAGNOSTIC ACCURACY OF CORONARY OPACIFICATION DERIVED FROM CORONARY COMPUTED TOMOGRAPHY ANGIOGRAPHY TO DETECT ISCHEMIA: FIRST VALIDATION VERSUS SINGLE-PHOTON EMISSION COMPUTED TOMOGRAPHY

Abstract Background Estimation of functional relevance of a coronary stenosis by fractional flow reserve (FFR) from coronary computed tomography angiography (CCTA) has recently provided encouraging results.Due to its limited availability, the corrected contrast opacification (CCO) decrease and the transluminal attenuation gradient (TAG) were sugges

Nutritional iron deficiency anemia is considered the main public health problem of poor less-developed and developing countries.The World Health Organization has estimated that 1.5-2.0 billion persons are anemic.It has been said that close to 1 million deaths are linked to iron deficiency anemia.The groups most vulnerable to this form of anemia are

The exploration of the energy landscape of a chemical system is essential for understanding and predicting its observable properties.In most cases, this is a challenging task due to the high complexity of such landscapes, which often consist of multiple, possibly hierarchical basins that are difficult to locate and thoroughly explore.In this study,

We developed a computational model of the propagation of retinal ischemia in diabetic retinopathy and analyzed the consequences of various patterns and sizes of burns in peripheral retinal photocoagulation.The model addresses retinal ischemia as a phenomenon of adverse local feedback in which once a capillary is occluded there is an elevated probab
