BACKGROUND Ischemia reperfusion injury (IRI) is a leading cause of acute kidney injury (AKI) in both native and transplanted kidneys. The objective of the present study was to evaluate whether low-molecular-weight fucoidan (LMWF) could attenuate renal IRI in an animal model and in vitro cell models and study the mechanisms in which LMWF protected from IRI. METHODOLOGY/PRINCIPAL FINDINGS Male ...
BACKGROUND Intestinal ischemia-reperfusion injury (IRI) can occur in clinical scenarios such as organ transplantation, trauma and cardio-pulmonary bypass, as well as in neonatal necrotizing enterocolitis or persistent ductus arteriosus. Pharmacological protection by pretreating ("preconditioning") with opioids attenuates IRI in a number of organs. Remifentanil appears particularly attractive fo...
Background: Renal ischemia-reperfusion (I/R) is an important Etiopathological mechanism of acute renal failure (ARF). It occurs during renal transplantation and leads to reduced allograft survival. Deterioration of kidney function is associated with disturbance in hypothalamic-pituitarygonadal (HPG) axis. Hypoxia-inducible factor-1 α (HIF-1 α ) plays an essential role in cellular and systemic o...
Background:Troxerutin has antioxidant and anti-inflammatory properties and in this study, its antioxidant effect on the reduction of oxidative stress induced by ischemia-reperfusion sciatic nerve injury was investigated. Methods:In this study, 64 male rats were randomly divided into 8 groups as follows: 1- IR2: ischemia (3 hours) and reperfusion (2 days), 2- T...
BACKGROUND The protective role of IL-11, an IL-6 family cytokine, has been implicated in ischemia/reperfusion injury (IRI) in the heart and kidney, but its role has not been elucidated in liver IRI. This study was designed to evaluate the effects of IL-11 and its mechanism of action on liver IRI in a mouse model. METHODS A partial (70%) warm liver IRI was induced by interrupting the artery/po...
Reactive oxygen species induce formation of 15-F(2t)-isoprostane (15-F(2t)-IsoP), a specific marker of in vivo lipid peroxidation, which is increased after myocardial ischemia and during the subsequent reperfusion. 15-F(2t)-IsoP possesses potent bioactivity under pathophysiological conditions. However, it remains unknown whether 15-F(2t)-IsoP, by itself, can influence myocardial ischemia-reperf...
conclusions treatment with epo and mel had a beneficial effect on renal ir injury. the results may also indicate that mel protects against morphological damage better than epo in renal ir injury. results ischemia-reperfusion significantly decreased the observed hb and hct values. the histopathological findings in the ir group confirmed that there was an increase in the hyaline cast and thickeni...
BACKGROUND/AIMS Renal ischemia/reperfusion injury (IRI) is a very common clinical event and usually leads to ischemic acute renal failure (ARF). In the present study, we investigated the protective role of vitamin C in renal function and renal arterial relaxation following ischemic injury. METHODS IRI model in mice was used. Various biochemical parameters including nitric oxide (NO), reduced ...
BACKGROUND Large body of evidences accumulated in clinical and epidemiological studies indicate that hearts of diabetic subjects are more sensitive to ischemia reperfusion injury (IRI), which results in a higher rate of mortality at post-operation than that of non-diabetes. However, experimental results are equivocal and point to either increased or decreased susceptibility of the diabetic hear...
BACKGROUND Ischemia-reperfusion injury (IRI) is a major cause of cardiac damage following various pathological processes. Gaseous hydrogen sulfide (H2S) is protective during IRI by inducing a hypometabolic state in mice which is associated with anti-apoptotic, anti-inflammatory and antioxidant properties. We investigated whether gaseous H2S administration is protective in cardiac IRI and whethe...
