Obj.ctive: To determine the feasibility and safety of skeletal myoblast transp lantation in patients with chronic myocardial infarction undergoing coronary art ery bypass grafting. Methods: Twelve patients with a previous myocardial infarct ion and ischemic coronary artery disease underwent treatment with coronary arter y bypass grafting surgery and intramyocardial inj.ction of autologous skeletal m yoblasts cultured with autologous serum. Global and regional cardiac function wa s assessed by echocardiogram. Fluorine 18 fluorodeoxyglucose and nitrogen 13-am monia positron emission tomography studies were used to determine cardiac viabil ity and perfusion. A group of historical control patients(n=14) treated with coronary artery bypass grafting surgery wi thout myoblast transplantation was analyzed. Results: The left ventricular ej.ct ion fraction improved from 35.5%±2.3%(mean±SEM) before surgery to 55.1%±8. 2%at 12 months(Pj.nction with coron ary artery bypass is safe and feasible and is associated with an increased globa l and regional left ventricular function, improvement in viability, and perfusio n of cardiac tissue and no significant incidence of arrhythmias.

Background To detect and identify mosquitoes using their characteristic high-pitched sound,we have developed a smartphone application,known as the‘HumBug sensor’,that records the acoustic signature of this sound,along with the time and *** data is then sent remotely to a server where algorithms identify the species according to their distinctive acoustic *** this system works well,a key question that remains is what mechanisms will lead to effective uptake and use of this mosquito survey tool?We addressed this question by working with local communities in rural Tanzania and providing three alternative incentives:money only,short message service(SMS)reminders and money,and SMS reminders *** also had a control group with no *** A multi-site,quantitative empirical study was conducted in four villages in Tanzania from April to August *** participants(n=148)were recruited and placed into one of the three intervention arms:monetary incentives only;SMS reminders with monetary incentives;and SMS reminders *** was also a control group(no intervention).To test effectiveness of the mechanisms,the number of audio uploads to the server of the four trial groups on their specific dates were *** focus group discussions and feedback surveys were also conducted to explore participants’perspectives on their participation in the study and to capture their experiences of using the HumBug *** Qualitative data analysis revealed that for many participants(37 out of 81),the main motivation expressed was to learn more about the types of mosquitoes present in their *** from the quantitative empirical study indicate that the participants in the‘control’group switched on their HumBug sensors more over the 14-week period(8 out of 14 weeks)when compared to those belonging to the‘SMS reminders and monetary incentives’trial *** findings are statistically significant(p0.95 under a tw
