Ischemia/reperfusion injury associated with kidney transplantation induces profound acute injury, influences early graft function, and affects long-term graft outcomes. To determine whether renal dendritic cells play any role during initial innate ischemia/reperfusion injury and the subsequent development of adaptive immune responses, we studied the behavior and function of renal graft and host...

OBJECTIVE Acute renal failure remains a major challenge in critical care medicine. Both neutrophils and chemokines have been proposed as key components in the development of acute renal failure. Although the Duffy antigen receptor for chemokines (DARC) is present in several tissues and a highly specific ligand for various chemokines, its exact role in vivo remains unclear. DESIGN Prospective,...

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...

AIMS AND OBJECTIVES Acute renal failure is a severe complication of lower extremity major arterial reconstructions, which could even be fatal. Levosimendan is a dual-acting positive inotropic and vasodilatory agent, which is suspected to have protective effects against cardiac ischemia. However, there is no data available on lower limb or remote organ ischemic injuries therefore the aim of the ...

Although altered renal vascular reactivity is known to occur after ischemia, the structural basis explaining the phenomenon has not been clarified. To evaluate for structural damage to the renal vasculature in ischemic acute renal failure (ARF), F-actin in the renal vasculature of rat kidneys and cultured vascular smooth muscle cells was examined using confocal fluorescence microscopy. The left...

Present study was designed to evaluate in Renoprotective activity of Pioglitazone and Glimepiride on Ischemia/reperfusion (I/R) induced renal damage in diabetic rats. Ischemia/reperfusion injury, which is commonly seen in the field of renal surgery or transplantation in diabetic condition, is a major cause of acute renal failure. Type 2 Diabetes was induced in rats by a single intraperitoneal (...

Aims: Renal vascular clamping during partial nephrectomy can lead to renal ischemia and kidney damage due to reperfusion injuries, but a surgical technique without any ischemia can eliminate such unwanted effects on kidney function. The present study aimed to demonstrate the feasibility of partial nephrectomy in conditions where the renal artery is ready to be clamped. Patient Information: In ...

ischemia-reperfusion injury is the tissue damage happened when blood supply returns to the tissue after a period of ischemia or shortage of oxygen. this brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. the aim of this study is investigating the effect of hydroalcoholic extract of  cyperus rotundus l. on the expression of the bcl-x1 an...

To elucidate the role of a proteasome-dependent proteolytic pathway in the pathogenesis of acute renal failure (ARF), we examined the effect of a selective proteasome inhibitor, lactacystin, on ARF induced by ischemia/reperfusion. Ischemic ARF was induced by clamping the left renal artery and vein for 45 min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal function in unt...

BACKGROUND Thioredoxin (TRX) is a small protein with redox-regulating functions. Although TRX is known to be induced in response to various forms of oxidative stress, including ischemia/reperfusion injury, the induction and the specific role of this protein in the kidney have not been fully investigated. METHODS Renal ischemia/reperfusion was induced by the clipping and release of renal arter...
