Network-on-Chip (NoC) designs have emerged as a replacement for traditional shared-bus designs for on-chip communications. Typically, these systems require fully balanced clock distribution trees to enable synchronous communication between all nodes on-chip, resulting in higher power consumption. One approach to reduce power consumption is to replace the balanced clock tree with a globally-asyn...

We designed a nonroller extra-corporeal circulation system (NRECC) to minimize space requirements and to improve the safety and ease of cardiopulmonary bypass. The NRECC includes a circuit, a centrifugal pump, and a vacuum regulator. The vacuum regulator has five channels, each of which can control negative pressure independently. Negative pressure is applied to suctions, a vent, and a venous r...

The purpose of the present research is to investigate the effective channels of the monetary transmission mechanism in Iran. To do so, we devised a New Keynesian Dynamic Stochastic General Equilibrium Model. In our model, the different types of nominal rigidities are introduced beside all the related structural equations, which are extracted and linearized around a steady state point. Furthermo...

background : cardiovascular operations are associated with an inherent bleeding tendency that sometimes leads to severe bleeding and transfusion requirement. pharmacological intervention to minimize post-bypass bleeding and blood product transfusions has received increasing attention from both medical and economic viewpoints. methods: this double-blind, randomized, placebo-controlled clinical t...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

background: euroscore is a simple and rigorous risk stratification model and is, thus, commonly used in predicting the early and late outcomes of cardiac surgery across the world. we aimed to assess the discriminative power of the euroscore model to predict postoperative morbidity and total prolonged length of stay in hospital (los) and intensive care unit (icu) stay in an iranian group of card...

background: reducing blood pressure through diet decreases the possibility of heart attacks, and lowering blood cholesterol can reduce the risk of coronary artery disease. the aim of the present study was to examine the effects of education based on the health belief model on the dietary behavior of patients following coronary artery bypass graft surgery (cabg) at the heart surgery department o...

background higher life expectancy and increased ischemic heart disease (ihd) have resulted in increasing number of the elderly patients undergoing cardiac surgeries. age along with many other comorbidities influence the outcome of major surgeries in the elderly patients; hence, case selection before major surgeries is challenging. objectives the pure effect of age after adjusting for other majo...

conclusions our study showed that desmopressin could not reduce the amount of blood loss after cabg. also, desmopressin did not have a significant effect on coagulation status. therefore, based on the results of our study, it seems that the use of this medication cannot be a helpful for patients with any indication for cabg. background coronary artery bypass grafting (cabg) is a common surgical...

conclusions the findings of this study indicate that oral pregabalin (300 mg dose) can alleviate patients’ pain and nausea/vomiting and notably reduce adverse effects. results a total of 60 patients were compared; 30 patients in each of the pregabalin and control groups. both groups were similar in age and sex distribution. mean pain intensity levels during the whole follow up were lower in the...
