BACKGROUND Cellular cardiomyoplasty is emerging as a potentially novel therapeutic option for heart failure and typically involves direct intramyocardial injection of donor cells into a beating heart. Yet, limited rates of cell engraftment remain an obstacle to be overcome before cell therapy is fully recognized. Mechanical and biological mechanisms may account for observed donor cell loss. Thi...

This study has been conducted in an effort to establish metabolic and inflammatory responses of the myocardium during aortic valve surgery on the beating heart with CPB and continuous coronary sinus perfusion with normothermic blood. Twenty patients, divided into two groups, participated in this study. Conventional aortic valvular operations were performed on first 10 patients, while the second...

ABSTRCT: High-speed cold roll-beating forming technique is a new near-net plastic forming method that the intermittent high-speed roll-beating is used to achieve dynamic impact local loading, and that is fast, transient, high impact, large deformation of the complex forming process. For this forming process, the main stress method is employed to derive an analytic formula for the deformation fo...

The shortage of organ donors remains a major obstacle in transplantation in Hawaii. Some patients die while waiting for a life-saving organ. Across the nation, "marginal" donors, including non-heart-beating donors are used. The authors describe the first successful non-heart-beating organ donor transplant in Hawaii, and include medical and ethical considerations.

Beating of monopole modes in nuclear dynamics. Abstract Time-dependent Hartree-Fock simulations of the evolution of excited gold fragments have been performed. The observed dynamics appears more complex than the collective expansion picture. The minimum density is often not reached during the first density oscillation because of the beating of several collective compression modes.

OBJECTIVE To study the differences in the prevalence of neurological complications following coronary artery bypass (CAB) carried out by conventional, on-pump beating and off-pump techniques. METHODS A retrospective analysis of all isolated coronary bypass operations (n=127) performed in King Fahad Cardiac Center, Riyadh over a period of one year starting from January 2005. Out of 127 patient...

background: the 5% to 25% prevalence of post-traumatic stress disorder (ptsd) during life-time can cause irrefutable harms an individuals and society. this research carried out to examine or not eye movement desensitization and reprocessing (emdr) treatment can improve ptsd symptoms. materials and methods: 71 patients (56 females and 15 males) have been selected randomly. demographic and kind o...

OBJECTIVES This study was conducted to investigate the effects of thyroid hormone on the electrophysiological characteristics of pulmonary vein (PV) cardiomyocytes. BACKGROUND Hyperthyroidism is an important etiology of paroxysmal atrial fibrillation (AF). Pulmonary veins are known to initiate paroxysmal AF. METHODS The action potential and ionic currents were investigated in single rabbit ...
