OBJECTIVE We developed an individualized off-pump approach in an all internal thoracic artery (AITA) composite graft revascularization (AITACR) program to minimize postoperative neurological complications and to obtain the best long-term results possible. Early results of the individualized approach are reported. PATIENTS AND METHODS The operative method (on-pump or off-pump) was determined b...

BACKGROUND This prospective non-randomized clinical study was done to compare Off-pump and On-pump myocardial revascularization by Troponin I release in patients undergoing first elective coronary artery bypass graft used to evaluate myocardial injury. METHODS One hundred an twenty patients were non-randomly assigned to a Off-pump or On-pump myocardial revascularization group. Cardiac Troponi...

this study represents effect of four variables in performance of a heat-pump in two cities of tehran and rasht. a computer program has been developed, simulating a certain heat pump acting in different environments with different refrigerants in heating season. the analysis is based on a homogeneous model. effect of different refrigerants, depth of the buried heat exchangers and moisture conten...

legionella pneumophila is the pathogen responsible for severe pneumonia known as legionnaires’ disease. legionella can live under varied stress conditions, especially in cold environments, and is common in many artificial environments. in this study, the antimicrobial activity of biogenic silver nanoparticles, prepared using the culture supernatant of klebsiella pneumoniae, was evaluated agains...

this paper presents a fuzzy search controller approach along with the look-up tables, to optimize the efficiency of a pump-induction motor drive. the induction motor and the converter are modeled based on thermal loss; and for modeling the pump and the hydraulic system, which are non-linear and relatively complicated, the neural network is used. in the designed system, in order to optimize the ...

conclusions the occurrence of he is associated with hyponatremia and ppi use in patients with aclf. results in univariate analysis, patients with he in aclf had a significantly higher rate of ppi use (89.1%) compared with non-he (63.6%, p = 0.001). in addition, clinical and standard laboratory variables were significantly different between the two groups regarding the infection rate, hyponatrem...

objective(s):pantoprazole, is a proton pump inhibitor (ppi) prescribed for the treatment of upper gastrointestinal disorders, which in high doses has been suggested to decrease calcium absorption leading to hypocalcaemia and therefore osteoporosis. the aim of this study was to assess whether pantoprazol, could alter the rate of orthodontic tooth movement (otm) in rats. materials and methods: a ...

BACKGROUND The effect of the use of coronary-artery bypass surgery without cardiopulmonary bypass and cardiac arrest ("off pump") on graft patency remains uncertain. We undertook a prospective, randomized, controlled study to compare graft-patency rates and clinical outcomes in off-pump surgery with conventional, "on-pump" surgery. METHODS We randomly assigned 50 patients to undergo on-pump c...

BACKGROUND It has been well documented that women have higher morbidity and mortality rates than men following coronary artery bypass graft (CABG) surgery. In view of this evidence, it is necessary to know if there is benefit to off-pump CABG surgery in women in comparison to on-pump CABG. OBJECTIVES Compare outcomes between off-pump CABG and on-pump CABG in women. METHODS Retrospective stu...
