This study was designed to elucidate the role of peroxisome proliferator-activated receptor (PPAR)-alpha in the development of inflammation after ischemia/reperfusion injury of the kidney. We have evaluated the effects of ischemia/reperfusion on renal dysfunction, injury, and inflammation in wild-type mice or mice in which the gene for PPAR-alpha has been deleted [PPAR-alpha(-/-)] and then trea...

There are many reasons for solitary kidney. Congenital causes include renal agenesis and dysplasia. Acquired nephrectomy performed including traumatic kidney injury, disease (e.g., cell carcinoma), donation transplantation. According to the European Association of Urology, World Society Emergency Surgery, American Surgery Trauma guidelines, it is important preserve remaining function as much po...

Autophagy is important for cellular survival during renal ischemia/reperfusion (I/R) injury. Ischemic preconditioning (IPC) has a strong renoprotective effect during renal I/R. Our study here aimed to explore the effect of IPC on autophagy during renal I/R injury. Rats were subjected to unilateral renal ischemia with or without prior IPC. Hypoxia/reoxygenation (H/R) injury was induced in HK-2 c...

OBJECTIVE To study the effect of erythropoietin (EPO) treatment on renal and lung injury following renal ischemia/reperfusion (I/R). MATERIALS AND METHODS Thirty male Wistar rats were assigned to three groups of 10 rats each. The first group was sham-operated, the second was subjected to renal I/R (30 min of ischemia followed by 24 h of reperfusion). The third group was subjected to renal I/R...

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...

Ischemia/reperfusion (I/R) injury is a common cause of injury to target organs such as brain, heart, and kidneys. Renal injury from I/R, which may occur in renal transplantation, surgery, trauma, or sepsis, is known to be an important cause of acute kidney injury. The detailed molecular mechanism of renal I/R injury is still not fully clear. Here, we investigate the role of AMP-activated protei...

Meldrum, Kirstan K., Daniel R. Meldrum, Xianzhong Meng, Lihua Ao, and Alden H. Harken. TNF-dependent bilateral renal injury is induced by unilateral renal ischemiareperfusion. Am J Physiol Heart Circ Physiol 282: H540–H546, 2002; 10.1152/ajpheart.00072.2001.—While tumor necrosis factor (TNF)is an important mediator of renal ischemiareperfusion (I/R) injury, its role in contralateral renal injur...

We previously demonstrated that renal peptidyl arginine deiminase-4 (PAD4) is induced after renal ischemia and reperfusion (I/R) injury and exacerbates acute kidney injury (AKI) by increasing the renal tubular inflammatory response. Here, we tested whether genetic ablation of PAD4 attenuates renal injury and inflammation after I/R in mice. After renal I/R, PAD4 wild-type mice develop severe AKI...

results there are many pitfalls in diagnosis of utis both with urinalysis and culture methods and also in evaluating the risk factors and causes of utis. conclusions this paper reviews and discusses the common pitfalls in diagnosis and evaluation of utis in children. context urinary tract infections (utis) are among the most common infections in children that affect up to 3% of boys and 8% of g...

BACKGROUND Despite broad clinical use of the American Association of the Surgery of Trauma (AAST) injury scale for kidney, it has only been found to predict the need for renal surgery in single institution series. We sought to validate this scheme for morbidity and mortality in a national cohort of patients with renal injury. METHODS A retrospective cohort design was used to determine the ass...
