Meanings of perfused hearts in English

In Langendorff perfused hearts, atrial conduction was studied using a 16-electrode array.

There were no significant differences in action potential morphology in paced Langendorff- perfused hearts.

We performed epicardial ventricular activation mapping on adult and senescent Langendorff perfused hearts.

Furthermore, 5-HT increased contractility in isolated perfused hearts from TG mice but not WT mice.

Better preservation of reactive hyperemia early in reperfusion may explain the better performance of blood perfused hearts.

Unlike other indictors, rhod 2 rapidly loaded in perfused hearts and was completely converted to the free acid form.

Methods: Both isolated perfused hearts and isolated ventricular myocytes from GK and matched control Wistar rat hearts were studied.

Mouse hearts perfused in the presence of insulin demonstrated accelerated glycolysis and glucose oxidation rates as compared with non-insulin- perfused hearts.

In addition, the DCD hearts are exposed to an intense catecholamine surge that is not seen with ex vivo perfused hearts.

Moreover, beneficial effects of endothelial Cx40 were not observed in isolated Langendorff- perfused hearts, suggesting direct involvement of endothelial-leucocyte interactions in the cardiac injury.

This study, which utilized coronary- perfused hearts and superfused papillary muscle, was designed to determine whether homocysteine acts acutely to alter cardiac contractile function.

Isolated, perfused hearts, Western blotting and flow-cytometric methods were utilized to determine myocardial function, expression and phosphorylation of key proteins and NO production, respectively.

Isolated perfused hearts from Sprague-Dawley rats were subjected to 35 minutes of regional ischemia and 120 minutes of reperfusion.

Isometric tension recordings and Langendorff experiments with isolated perfused hearts showed that NO-mediated relaxations were significantly enhanced, whereas EDH-mediated relaxations were markedly reduced in microcirculations.

Conclusions: Myocardial stretch induced by increasing LVEDP preconditioned isolated perfused hearts of both WKY rats and SHR, via mechanisms not involving myocardial ischemia during stretch.

In buffer- perfused hearts, functional recovery was recorded, and acute infarct size was measured using 1% triphenyltetrazolium chloride staining and lactate dehydrogenase release during reperfusion.
