Geron Demonstrates hESC-derived cardiomyocytes improve heart function after myocardial infarction

... cardiomyocytes, their survival in the infarct zone of rats when transplanted four days after ... of engraftment in the hostile environment of the infarct zone. Moreover, a portion of the cardiomyocytes ... increase in systolic wall thickening in the infarct zone relative to controls (0.01). Significance ...

Winners announced in the Elsevier Grand Challenge

... Researcher Disruptive Technologies and co-organizer of the Challenge. "It seems clear that there is no single solution to solving the information infarct in biology. Apart from helping develop some wonderfully innovative thinking about improved ways to publish and access science, the Challenge has ...

A stronger heart with flavonoids

... consumption and effective absorption of anthocyanins rendered the rats more resistant to myocardial infarction; in other words, the size of the infarct was significantly reduced in rats fed the anthocyanin-rich diet. The quantity of absorbed anthocyanins is important too. Maria Benedetta Donati, ...

Protein therapy may reduce infarct size in heart attack patients

... Researchers are searching for new methods and therapies to reduce infarct size and improve blood flow to the heart muscle in patients who experience ... implantation and by continuous electrocardiogram recordings) and reduced infarct size (measured 14 days after the heart attack) were observed at the 0.5 mg ...

Potential heart benefit found in stem cells

... density of the corresponding capillaries in four areas: the damaged or infarct area, the healthy myocardium (cardiac muscle), and in two parts of the border zone. As predicted, the infarct areas of the heart walls in the ADSC group were thicker than in the ...

Stem cell mobilization therapy appears to be ineffective in repairing damage caused by heart attack

... of bone marrow stem cells. The researchers found that this did not alter infarct size (area of damage) or left ventricular function after a heart attack. ... based on sensitive assessment methods of left ventricular function and infarct size. In conclusion, use of G-CSF therapy to mobilize bone marrow–derived ...

Bone marrow stem cells may heal hearts even years after heart attacks

... velocity rose 57 percent, and there was a significant reduction of infarct size by 30 percent. Concerning all those parameters, no significant ... by 15 percent, which represents myocardial metabolism and viability, into infarct tissue was observed," Dr. Strauer said. "The stem cell therapy ...

Survival of heart patients on beta-blockers varies greatly with genetic variation

... from patients with acute myocardial infarction have shown that beta-blockers are generally effective. They are known to decrease the size of the infarct and seem to prolong survival, on average." Recent research, however, reveals that variations in the beta-adrenergic receptor genes affect the ...
