The evolutionary history of TUBBY-like proteins (TLPs), which contain a highly conserved tubby domain, can be traced to the early stages of eukaryote evolution, on account of the identification of this gene family in organisms from single-celled to multicellular eukaryotes. While genome-wide structural and evolutionary analyses of the entire TLP gene family(More)
OBJECTIVE Cardiac surgery, especially when employing cardiopulmonary bypass and deep hypothermic circulatory arrest, is associated with systemic inflammatory responses that significantly affect morbidity and mortality. Intestinal perfusion abnormalities have been implicated in such responses, but the mechanisms linking local injury and systemic inflammation(More)
This study examined the hypothesis that core temperature (T(o)) during cardiopulmonary bypass (CPB) influences the perioperative systemic inflammatory response and post-operative organ damage. Twenty-four pigs were assigned to a T(o) regimen during CPB: normothermia (T(o) 37 degrees C; n = 8), moderate hypothermia (T(o) 28 degrees C; n = 8), or deep(More)
BACKGROUND The control of the systemic inflammatory response taking place during cardiac operations depends on adequate antiinflammatory reaction. In this prospective study we tested the hypothesis that cytokine balance during pediatric cardiac surgical procedures would be influenced by the patients' preoperative clinical condition, defined as hypoxemia or(More)
OBJECTIVES We sought to test the hypothesis that cytokines would be expressed in the myocardium of infants with congenital cardiac defects and to identify the signaling pathways involved. BACKGROUND Mechanical stress upregulates pro-inflammatory cytokines in the myocardium. METHODS Fifteen infants with tetralogy of Fallot (TOF) (n = 7) or with(More)
Anti-thrombogenicity and rapid endothelialisation are prerequisites for the use of closure devices of intra-atrial communications in order to reduce the risk of cerebral embolism. The purpose of this study was therefore to assess the effect of bioactive coatings on biocompatibility of Nitinol coils designed for the closure of intra-atrial communications.(More)
SUMMARY OBJECTIVES To identify the signaling pathways involved in the anti-inflammatory shift of the cytokine balance due to hypothermia during cardiopulmonary bypass. DESIGN Experimental animal study. SETTING Department of experimental surgery of a university hospital. SUBJECTS Young pigs. INTERVENTIONS Animals underwent normothermic (37 degrees C) or(More)
OBJECTIVES The response to hypoxia is primarily mediated by the transcription factor hypoxia-inducible factor-1 (HIF-1) which leads to the induction of a variety of adaptive gene products including vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS). This study was designed to test the hypothesis that HIF-1 and its target(More)
OBJECTIVES The goal of this study was to test the hypothesis that moderate hypothermia during cardiopulmonary bypass (CPB) provides myocardial protection by enhancing intra-myocardial anti-inflammatory cytokine balance. BACKGROUND Moderate hypothermia during experimental CPB stimulates production of interleukin-10 (IL10) and blunts release of tumor(More)
OBJECTIVES This study was undertaken to test the hypothesis that the myocardial protective effect of moderate hypothermia during cardiopulmonary bypass involves upward regulation of heat shock protein 72. METHODS Sixteen young pigs were randomly assigned to a temperature regimen during standardized cardiopulmonary bypass of normothermia or moderate(More)
