OBJECTIVES The Arterial Revascularization Trial (ART) is a randomized comparison of bilateral internal mammary artery (BIMA) versus single internal mammary artery (SIMA) grafting in coronary artery bypass graft (CABG) surgery and is one of the largest randomized trials of surgery ever conducted. ART is also one of the largest studies of contemporary CABG with a high proportion of off-pump surge...

In this article, the impact of input pump profile on the gain spectrum as well as the saturation behavior of one-pump fiber optical parametric amplifiers (FOPAs) is investigated. Since in practical circumstances, pump sources used for FOPAs have Lorentz-Gaussian profile instead of Gaussian, a more realistic case is considered for simulating FOPAs in this article. The results of simulations for ...

Oil pump in diesel engine has significant effect on energy consumption and environment pollution. In this paper, the modeling and simulation of a gear oil pump used in a diesel engine and its fluid flow analysis by a solver has been explained. Also the optimization and redesign of it has been discussed and then the outcomes have been compared with the experimental and previous results. The t...

diabetic mellitus (dm) is a major risk factor of morbidity, mortality and economic cost to society. diabetic patients are at risk of having microvascular or macrovascular disorders of diabetes. postoperative anemia have wide spectrum of some early complications that require more care in hospitalization stays. therefore, this study was designed to evaluate effect of preoperative anemia on short-...

During cardiopulmonary bypass (CPB) the concentration of blood components is controlled by fluid administration and diuresis. However, diuresis is not always adequate and at the end of CPB the diluted pump blood, unless processed by expensive and cumbersome RBC saving techniques, is usually discarded. To control "diuresis" during CPB and to concentrate all blood components of the diluted pump b...

this pump could be used to irrigate the regions where ground water level is close to land surface and thire is enough wind energy in the region. since advanced pumps are costly, this pump is designed only to send up water one meter high with the flow of one.inexperimental fluid mechanics laboratory of orrsay france amodel of this pump was conducted. results show that the pump could be manufactu...

Many theoretical and practical problems arise at different stages of the design/manufacturing process during development of a pump. The experience obtained in pump development proves that the quality of a pump depends on many factors, which should he satisfied to receive good results. At the same time, the theory of engineering design principles exists, which is applicable to designing various ...

Left ventricular assist devices (LVADs) are now a durable mainstay of therapy for medically refractory advanced heart failure (HF). Continuous-flow LVADs demonstrated increased longevity and enhanced quality of life in a series of landmark trials, ushering in an era where more LVADs are now implanted annually than hearts transplanted. Less than 50% of current LVAD recipients are listed for hear...

Introduction: In the past decade, multidrug-resistant Acinetobacter baumannii has become one of the most critical challenges in treating infected patients. The AdeABC efflux pump is the most important among the various resistance mechanisms. This pump can force various antibiotics and ethidium bromide out of the bacterial cell to the surrounding environment. Methods: In this study, nine A. baum...
