Objective(s): Renal ischemia reperfusion (IR) contributes to the development of acute renal failure (ARF). Oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal IR. The purpose of this study was to investigate the effect of co-administration of melatonin (MEL) and erythropoietin (EPO), potent antioxidant and ...

Introduction: Renal ischemia/reperfusion (I/R) injury due to reactive oxygen species (ROS) formation is the main cause of acute kidney damage. Nitric oxide (NO) biosynthesis and oxidative stress are closely related to the pathogenesis of renal I/R injury. This study was undertaken to determine the effects of L-arginine (L-arg) as NO donor and aerobic exercise (EX) and also the combination of L-...

BACKGROUND There is debate as to whether, in patients with acute lung injury, continuous renal replacement therapy has beneficial effects on pulmonary gas exchange by mechanisms other than fluid removal. Because continuous renal replacement therapy is associated with potential morbidity and mortality, it seems unethical to perform a randomized trial in patients with acute lung injury without re...

Objective(s):Acute kidney injury (AKI), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  Renal ischemia-reperfusion, one of the main causes of AKI, is of particular importance in the setting of kidney transplantation. Materials and Methods: Sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

Introduction: Monoclonal Gammopathy of Renal Significance (MGRS) is an immunoglobulin proliferative disorder that leads to the destruction of the renal glomerular basement membrane and progression to end-stage renal disease. The pathogenesis of MGRS is similar to that of multiple myeloma and chronic lymphocytic lymphoma but lacks criteria for either disease. This inability to characterize the d...

Objective: To evaluate a mathematical model to study the dynamics of renal failure in patients with acute kidney injury. Methods: A mathematical model was applied to simulate the “dynamic path of renal lesion” in patients with acute kidney injury. results: The dynamics of glomerular filtration rate was simulated with the real data of a patient attended at the Intensive Care Unit. conclusions: T...

Acute renal failure is a frequent clinical problem with an increasing incidence, an unacceptably high mortality rate that has not improved in more than 40 years, and no specific treatment, yet renal failure is not the usual cause of death. The role of inflammation has been documented in both acute renal injury and cardiac dysfunction. Several investigators have shown that congestive heart failu...

Crush injury is a recognised cause of acute renal failure, histologically giving characteristic myoglobin casts in biopsy specimens. A similar syndrome can be precipitated by muscle damage associated with barbiturate overdose1 and carbon monoxide poisoning.2 We report a case of acute renal failure in which the renal biopsy specimen showed a typical "crush injury" appearance due to severe acute ...

Acute kidney injury causes significant morbidity and mortality in the community and clinic. Various pathologies, including renal and cardiovascular disease, traumatic injury/rhabdomyolysis, sepsis, and nephrotoxicity, that cause acute kidney injury (AKI), induce general or regional decreases in renal blood flow. The ensuing renal hypoxia and ischemia promotes the formation of reactive oxygen sp...
