BACKGROUND AND STUDY AIMS Small intestinal ischemia-reperfusion (IR) is a frequent, potentially life threatening phenomenon. There is a lack of non-invasive diagnostic modalities. For many intestinal diseases, visualizing the intestinal mucosa using endoscopy is gold standard. However, limited knowledge exists on small intestinal IR-induced, early mucosal changes. The aims of this study were to...
AIM Constitutive genetic deletion of the adaptor protein p66(Shc) was shown to protect from ischaemia/reperfusion injury. Here, we aimed at understanding the molecular mechanisms underlying this effect in stroke and studied p66(Shc) gene regulation in human ischaemic stroke. METHODS AND RESULTS Ischaemia/reperfusion brain injury was induced by performing a transient middle cerebral artery occ...
Self-reactive natural Abs initiate injury following ischemia and reperfusion of certain tissues, but their role in ischemic stroke is unknown. We investigated neoepitope expression in the postischemic brain and the role of natural Abs in recognizing these epitopes and mediating complement-dependent injury. A novel IgM mAb recognizing a subset of phospholipids (C2) and a previously characterized...
OBJECTIVES This study examined the impact of omentin on myocardial injury in a mouse model of ischemia/reperfusion (I/R) and explored its underlying mechanisms. BACKGROUND Obesity is a major risk factor for ischemic heart disease. Omentin is a circulating adipokine that is down-regulated by obesity. METHODS In patients who underwent successful reperfusion treatment after acute myocardial in...
Research in the field of ischemia-reperfusion injury continues to be plagued by the inability to translate research findings to clinically useful therapies. This may in part relate to the complexity of disease processes that result in intestinal ischemia but may also result from inappropriate research model selection. Research animal models have been integral to the study of ischemia-reperfusio...
BACKGROUND Nonlethal ischemia and reperfusion reduce ischemia-reperfusion-induced cell death, a phenomenon called ischemic preconditioning. In animal models, this potent endogenous protection is mimicked in vivo by administration of adenosine. In humans, exploitation of ischemic preconditioning is hindered by the lack of an appropriate in vivo model to study this phenomenon. To solve this probl...
The role of fatty acyl CoA synthetase (FACS) in ischemia/reperfusion (I/R) injury has not been well established. Our earlier studies showed that triacsin C, a selective FACS inhibitor, decreases endothelial nitric oxide synthase (eNOS) palmitoylation and increases nitric oxide (NO) in cultured human coronary endothelial cells. In the present study, we tested the hypothesis that triacsin C would...
Gonzalez LM, Moeser AJ, Blikslager AT. Animal models of ischemiareperfusion-induced intestinal injury: progress and promise for translational research. Am J Physiol Gastrointest Liver Physiol 308: G63–G75, 2015. First published November 20, 2014; doi:10.1152/ajpgi.00112.2013.—Research in the field of ischemia-reperfusion injury continues to be plagued by the inability to translate research find...
Objectives: Curcumin has anti-inflammatory and antioxidative properties. The objective of this study was to investigate the therapeutic effects of curcumin on functional disturbances, oxidative stress, and leukocyte infiltration induced by renal ischemia/reperfusion (I/R). Materials and Methods: Animals were randomly divided into 9 groups. The groups with 24-h reperfusion consisted of sham-24h,...
Abstract Introduction: Resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. The aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% O2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. Methods: Following 60 and 180 minutes of hyperoxia, rat hearts w...
