Resistance of transplanted mesenchymal stem cells (MSCs) in post-ischemic heart is limited by their poor vitality. Vascular-endothelial-growth-factor-A (VEGF-A) as such or slowly released by fibronectin-coated pharmacologically-active-microcarriers (FN-PAM-VEGF) could differently affect survival kinases and anti-apoptotic mediator (e.g. Bcl-2). Therefore(More)
Catestatin (CST) limits myocardial ischaemia/reperfusion (I/R) injury with unknown mechanisms. Clearly phosphoinositide-3-kinase (PI3K), protein kinase C (PKC) isoforms, including intra-mitochondrial PKCε, mitochondrial KATP (mitoKATP) channels and subsequent reactive oxygen species (ROS)-signalling play important roles in postconditioning cardioprotection,(More)
BACKGROUND In the presence of comorbidities the effectiveness of many cardioprotective strategies is blunted. The goal of this study was to assess in a hypertensive rat model if the early reperfusion with anti-hypertensive and pro-angiogenic Chromogranin A-derived peptide, Catestatin (CST:hCgA352-372; CST-Post), protects the heart via(More)
Postconditioning (PostC) modifies the early post-ischemic pH, redox environment, and activity of enzymes. We hypothesized that early acidosis in PostC may affect superoxide dismutase (SOD) and catalase (CAT) activities, may reduce 3-nitrotyrosine (3-NT) protein levels, and may increase S-nitrosylated (SNO) protein levels, thus deploying its protective(More)
Previous studies have shown that food ingestion is not capable of inhibiting the GHRH-induced GH release in anorexia nervosa, at variance with what is observed in normal subjects. Moreover, a cholinergic alteration has been hypothesized in this disorder. In a group of 24 anorectic patients in a stabilized phase of the illness, we tested, before and after a(More)
