OBJECTIVES To investigate dual-phase multi-detector computed tomography (MDCT) for assessing extent and severity of jeopardised and infarcted myocardium subtended by infarct-related artery (IRA), and its indication for revascularisation after acute myocardial infarction (AMI). Designs, setting and PATIENTS Prospective, single-centre study included 107 patients with uncomplicated post-AMI 3-7 ...

OBJECTIVES The purpose of this study was to investigate the hypothesis that circulation via collateral vessels to an infarct-related artery (IRA) is impaired with aging in patients with acute myocardial infarction (AMI). BACKGROUND Animal experiments have shown that advanced age blunts the development of new vessels in response to angiogenic cytokines. METHODS Of 3,573 consecutive patients ...

Introduction: This study designed to use remote ischemic post conditioning (RIPC) as a protective strategy during percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI) to reduce myocardial cells damage due to reperfusion injury. Methods: Sixty-one patients were divided into test group (32 patients) receiving RIPC and control group (29 patie...

We investigate here a number of variations of the Para-IRA, which is an Impulse Radiating Antenna configured for parachute delivery. We consider first two scale models of the Para-IRA with aluminum reflectors, and then we consider a full-scale version built from fabric. In the scale models, we first investigate the effect of using a large F/D ratio in an IRA. We then investigate the effect of u...

The kinetics of exchange of Ru(III) at extremely low concentration on the strongly basic anion exchanger IRA-410 has been studied by means of finite volume method. The rate of exchange of Ru(III) studied as function of different parameters, the concentration, the particle size of the exchanger and temperature. The apparent activation energy obtained is 48.75±0.07 and 16.8 kJmol for IRA-410. The...

Recently, growing evidence demonstrates that recanalization of chronic total occlusion (CTO) lesions exerts a beneficial effect in terms of improvement in left ventricular function and long-term survival by alleviating residual/recurrent angina, and reduces the need for coronary artery bypass grafting. However, it remains unclear whether successful recanalization of a CTO in the non-infarctrela...

Después de años sin ensayos clínicos aleatorizados y controlados en el ámbito de la insuficiencia renal aguda (IRA) en pacientes críticos, se han publicado recientemente los resultados de 2 importantes ensayos clínicos, AKIKI1 y ELAIN2, que tratan de resolver las dudas acerca del mejor momento para iniciar la diálisis en pacientes graves con IRA. A pesar de décadas de investigación, la incidenc...

In this paper, capacity-achieving codes for memoryless binary-input output-symmetric (MBIOS) channels under maximum-likelihood (ML) decoding with bounded graphical complexity are investigated. The graphical complexity of a code is defined as the number of edges in the graphical representation of the code per information bit and is proportional to the decoding complexity per information bit per ...

Introdução: Dentre as inúmeras possibilidades que um indivíduo possui de experienciar e expressar a raiva ou ira, não é raro o sentimento fuja do controle termine em hostilidade agressões, podendo gerar consequências importantes na vida uma pessoa outros ao seu redor. Diante disso, torna-se fundamental aplicação técnicas comprovadamente eficazes, objetivando maior qualidade às pessoas com ele c...

Weakly supervised learning applies image tag labels to train convolutional neural networks locate defect. In industrial vision system, metal surface is anisotropic under light in all directions and it inevitable cause local overexposure due the natural reflection of active strong light, especially on cylindrical surface. this paper, injector valve taken as representative workpieces. Since varie...
