TLRs are an evolutionarily conserved family of cell membrane proteins believed to play a significant role in innate immunity and the response to tissue injury, including that induced by ischemia. TLR signaling pathways activate transcription factors that regulate expression of prosurvival proteins, as well as proinflammatory cytokines and chemokines through one of two proximal adapter proteins,...

BACKGROUND Despite a genomic revolution in biological sciences, clinical medicine has yet to integrate diagnostics based upon gene expression into practice. While commonly used plasma protein assays rely on organ-specific origins, nearly all nucleic acid in whole blood is derived from white blood cells limiting their utility to diagnose non-immune disorders. The aim of the study was to use cell...

Neutrophil gelatinase-associated lipocalin (NGAL) is one of the most promising candidate biomarkers of renal injury, with expression in renal tissue increasing dramatically after ischemia-reperfusion injury but not in the case of pure pre-renal failure. In a recent issue of Critical Care, Di Somma and colleagues reported that NGAL could improve the classification of acute kidney injury compared...

ecstasy (mdma; 3,4-methylenedioxymethylamphetamine) is an illicit drug that has been increasingly abused by young people. its effects include euphoria, enhanced sociability and heightened mental awareness. these come about via the increase of serotonin in both the central nervous system and the sympathetic nervous system. despite the drug’s prevalent abuse, serious or adverse effects are rare. ...

background considering the significant geographical and ethnical differences in pattern of incidence, etiology and outcome of chronic kidney disease (ckd), the present study aimed to assess the etiology and outcome of ckd in iranian children. materials and methods in a cross-sectional study etiology and outcome of 372 children aged 3 months to 18 years with ckd was studied during the period 199...

background serum creatinine as a classic marker of renal function has several limitations in the detection of renal dysfunction. objectives this study assessed the validity of serum cystatin c as a marker of renal function in critically ill patients with normal serum creatinine. patients and methods eighty adult patients referred to intensive care units with serum creatinine levels < 1.5 mg/dl ...

Fas-mediated apoptosis has been suggested to contribute to tubular cell death after renal ischemia-reperfusion injury. Here we investigate whether small interfering RNA (siRNA) duplexes targeting Fas protect mice from acute renal failure after clamping of the renal artery. Renal ischemia-reperfusion injury was induced by clamping the renal vein and artery for 15 or 35 min. Mice were treated bef...

renal ischemia-reperfusion (ir) injury is a common problem in kidney transplantation. there is increasing evidence about the role of the reactive oxygen species (ros) in these injuries and endogenous antioxidants seem to have an important role in decreasing the renal tissue injury. the aim of this study was to investigate the effects of kidney ir on renal antioxidant enzymes activity such as ca...

BACKGROUND One of the most common causes of acute kidney injury (AKI) is kidney ischemia/reperfusion injury (IRI). The distant organ injury such as acute lung injury is one of the side effects of AKI or kidney IRI. In this study, we performed bilateral renal IRI in rats and the protective role of N-acetylcysteine (NAC) in kidney and lung was investigated. METHODS Rats (n = 30) were randomly a...
