BACKGROUND Ischemic preconditioning (IPC) is a mechanism protecting tissues from injury during ischemia and reperfusion. Remote IPC (RIPC) can be elicited by applying brief periods of ischemia to tissues with ischemic tolerance, thus protecting vital organs more susceptible to ischemic damage. Using a porcine model, we determined whether RIPC of the limb is(More)
BACKGROUND/AIMS To examine whether intestinal bacterial translocation occurs early in acute mild and severe pancreatitis and whether the intestinal expression of tight junction proteins (claudins-2, -3, -4, -5, -7), apoptosis or proliferation would explain the possible translocation. METHODOLOGY Fifteen pigs were randomized to controls (n=5) or to develop(More)
OBJECTIVES Bone marrow mononuclear cells (BM-MNCs) can ameliorate focal ischaemic brain injury. A global ischaemic brain injury, which can occur after cardiac or thoracic surgery, could be an essential target for BM-MNCs. No studies using BM-MNCs for this indication have been conducted. DESIGN Ten porcine underwent a global normothermic ischaemic insult,(More)
BACKGROUND Remote ischemic preconditioning is a novel method of reducing ischemia-reperfusion injury in which a transient ischemic period of the limb provides systemic protection against a prolonged ischemic insult. This method of preconditioning has shown some potential in ameliorating ischemia-related injury in various organs and experimental settings. We(More)
Stem cell therapy represents a potential novel additional therapy for acute myocardial infarction. Cardiac applications of stem cell therapy are now undergoing clinical trials though many properties, including localization, possible adhesion, and infiltration of the injected stem cells in the myocardium, have not been studied in detail even in vitro. To(More)
BACKGROUND Acute myocardial infarction (AMI) launches an inflammatory response and a repair process to compensate cardiac function. During this process, the balance between proinflammatory and anti-inflammatory cytokines is important for optimal cardiac repair. Stem cell transplantation after AMI improves tissue repair and increases the ventricular ejection(More)
OBJECTIVE The clinical data considering the bone marrow mononuclear cell (BMMNC) therapy in treatment for acute myocardial infarction (AMI) are controversial and the mechanisms remain unknown. Our objective was to study the cardiac function and changes in cytokine levels after administration of BMMNC in experimental AMI model. DESIGN Unlabeled or(More)
