Evaluation of experimental myocardial infarction models via electromechanical mapping and magnetic resonance imaging.

The diagnostic characteristics of electromechanical mapping (EMM) were evaluated in porcine myocardial infarction (MI) models with the parallel application of cardiac magnetic resonance imaging (cMRI) from the aspect of different pathophysiology and localization. Balloon occlusion in the left anterior descending coronary artery (LAD balloon group) or coil deployment in the LAD (LAD coil group) or circumflex artery (Cx coil group) was applied percutaneously in 16 domestic pigs. Regional left ventricular viability data were captured via cMRI and EMM.

Intraamygdaloid microinjection of acylated-ghrelin influences passive avoidance learning.

The brain-gut peptide acylated-ghrelin (A-Ghr) is a potent growth hormone (GH) secretagogue substance. A-Ghr is also known to influence on memory and learning processes. Its effect is mediated partly via GH secretagogue receptor (GHS-R) type 1a.

Effects of intraamygdaloid microinjections of acylated-ghrelin on liquid food intake of rats.

Ghrelin (Ghr) has two main forms in the blood: the acylated (A-Ghr) and non-acylated (NA-Ghr) Ghr. A-Ghr was discovered as a potent growth hormone (GH) secretion increasing substance acting on GH secretagouge receptor (GHS-R) type 1a. A-Ghr facilitates food intake after its i.
