— We define analog product codes as a special case of analog parallel concatenated codes. These codes serve as a tool to get some more insight into the convergence of " Turbo " decoding. We prove that the iterative " Turbo "-like decoding of analog product codes indeed is an estimation in the least-squares sense and thus correspond to the optimum(More)
AIMS Congestive heart failure (CHF) can be thought of as a state of chronic immune activation. Polymorphonuclear neutrophil (PMN) apoptosis is one of the mechanisms responsible for the resolution of inflammation. A reduced PMN apoptotic rate in CHF patients may generate a persistent inflammatory response and hence mediate tissue damage in this group of(More)
MicroRNAs have been proposed as novel regulators of vascular inflammation and dysfunction. This study aimed to evaluate the role of miR-149 in regulating the expression of key molecules associated with TNFα-induced endothelial activation. miR-149 was selected by in silico analysis and microRNA target prediction. Endothelial dysfunction was induced by TNFα(More)
Nowadays, engineering studies are characterized by high mobility of students, lecturers and workforce and by the dynamics of multinational companies where " classes " or " students' teams " composed of persons with different competencies and backgrounds, working together in projects to solve complex problems. Such an environment will become increasingly(More)
BACKGROUND Insulin-like growth factor-1 (IGF-1) promotes the survival of cardiomyocytes by activating type 1 IGF receptor (IGF-1R). Within the myocardium, IGF-1 action is modulated by IGF binding protein-3 (IGFBP-3), which sequesters IGF-1 away from IGF-1R. Since cardiomyocyte apoptosis is implicated in anthracycline cardiotoxicity, we investigated the(More)
Cell attachment is provided by cell-matrix and cell-cell bonds, and acts as a regulator of vascular smooth muscle cell (VSMC) survival, activity and homeostasis, as well as of VSMCs response to pathogenic stimuli. In this work we elicited an exclusive cell-cell contact by culturing A7r5 VSMCs on agarose-coated wells to form floating cell clusters, and we(More)
This study proposes an alternative technique to prevent heat degradation induced by classic procedures of bioactive compound extraction, comparing classical maceration/decoction in hot water of polyphenols from Mango (Mangifera indica L.) (MI) with ultrasound-assisted extraction (UAE) in a water solution of β-cyclodextrin (β-CD) at room temperature and(More)
PURPOSE One of the limitations emerged with both synthetic and degradable vascular grafts is the lack of endothelialization after implantation that is known to be the main reason leading to unfavourable outcomes. It emerges the need to find new strategies to promote a rapid endothelialization of the scaffold. Pleiotrophin is a growth/differentiation(More)
