Ischemia-reperfusion injury (IRI) is a common clinical consequence of hepatic surgery, cardiogenic shock, and liver transplantation. A steatotic liver is particularly vulnerable to IRI, responding with extensive hepatocellular injury. Autophagy, a lysosomal pathway balancing cell survival and cell death, is engaged in IRI, although its role in IRI of a steatotic liver is unclear. The role of au...
Ischemia reperfusion injury (IRI) is a major cause of delayed graft function. Recent studies have shown that selectins play an important role in IRI. Selectins bind to sialylated and fucosylated sLe(x) receptors, and two enzymes, fucosyltransferase IV (FucT-IV) and VII (FucT-VII), are important in the function of these receptors. We hypothesized that fucosyltransferase (FucT) enzymes were impor...
BACKGROUND Dexmedetomidine has shown beneficial effects in several inflammatory models, including ischemia-reperfusion injury (IRI). This study investigated whether the continuous infusion of dexmedetomidine could improve renal IRI in rats. METHODS Rats were subjected to either a sham operation and given pentobarbital (10 mg/kg/h; n=6) or were subjected to 45 minutes of renal ischemia and ane...
BACKGROUND Despite a significant improvement in the management of chronic kidney disease (CKD), its incidence and prevalence has been increasing over the years. Progressive renal fibrosis is present in CKD and involves the participation of several cytokines, including Transforming growth factor-β1 (TGF-β1). Besides cardiovascular diseases and infections, several studies show that Vitamin D stat...
Delayed neurological deterioration in the absence of direct cord insult following surgical removal and cord decompression is a rare but severe postoperative complication in a small subset of patients with intraspinal meningiomas. To date, the underlying pathophysiology of such a finding remains unclear and ischemia-reperfusion injury (IRI) is considered as the potential etiology in the literatu...
Stathmin-deficient mice develop fibrosis and show delayed recovery from ischemic-reperfusion injury.
In kidneys subjected to ischemic reperfusion injury (IRI) stathmin, a tubulin-binding protein involved in the regulation of mitosis, is expressed in dedifferentiated and proliferating renal tubule cells during the recovery phase. To ascertain the role of stathmin in the recovery from ischemic kidney injury, stathmin-deficient (OP18-/-) and wild-type (WT) animals were subjected to experimental I...
Acute myocardial infarction (AMI) is the leading cause of morbidity and mortality worldwide. Timely reperfusion is considered an optimal treatment for AMI. Paradoxically, the procedure of reperfusion can itself cause myocardial tissue injury. Therefore, a strategy to minimize the reperfusion-induced myocardial tissue injury is vital for salvaging the healthy myocardium. Herein, we investigated ...
BACKGROUND Endothelial dysfunction contributes to ischemia-reperfusion injury (IRI) and is reduced by ischemic preconditioning (IPC). IPC may involve activation of ATP-sensitive potassium channels (K(ATP)). We determined whether modulation of K(ATP) channels occurs in endothelial IPC in humans. METHODS AND RESULTS IRI of the forearm was induced by inflating a blood pressure cuff to 200 mm Hg ...
Background: Liver ischemia / reperfusion Injury (IRI) is one of the major causes of liver failure during various types of liver surgery, trauma and infections. The present study investigates the effect of dexsamethasone on the liver injury and inducible nitric oxide synthase gene expression during hepatic warm ischemia/reperfusion in rats. Materials and Methods: 24 male Wistar rats (200-250 g)...
Background: Paraplegia is a major devastating and unpredictable complication of spinal cord ischemic reperfusion injury (SC-IRI). Ischemic preconditioning (IPC) is a procedure whereby a brief episode of non-lethal ischemia to an organ produces protection against subsequent detrimental ischemic-reperfusion insult to that organ. It has been shown that IPC may not only induce a local protective ef...
