Background: The widely adopted Jablonski scoring system for reporting histological damage in kidney ischaemia reperfusion injury (IRI) provides a limited score documenting the degree of necrosis within tubular cells. IRI is a complex process that involves damage to various cellular components of the renal cortex and therefore there is a need to develop a more detailed scoring system. The aims o...

Ischemia and reperfusion injury (IRI) is a crucial contributor to the development of renal fibrosis. Ozone has been proposed as a novel medical therapy for various conditions, including organ IRI. The aim of this study was to investigate whether ozone oxidative preconditioning (OzoneOP) has a beneficial effect in preventing the development of renal fibrosis following IRI. Sprague Dawley rats we...

Mesenchymal stem cells (MSCs) are a potential therapeutic tool for preventing the progression of acute kidney injury (AKI) to chronic disease (CKD). Herein, we investigated localization and maintenance engrafted human bone marrow-derived MSCs in rats subjected renal ischemia-reperfusion (IRI) compared effectiveness two intravascular injection routes via artery or inferior vena cava. Renal was m...

Ischemia-reperfusion injury (IRI) is inevitable during kidney transplantation leading to oxidative stress and inflammation. We previously reported that preoperative fasting in young-lean male mice protects against IRI. Since patients are generally of older age with morbidities possibly leading to a different response to fasting, we investigated the effects of preoperative fasting on renal IRI i...

PURPOSE To determine the pharmacokinetics and the antitumor activity in pediatric cancer models of MM-398, a nanoliposomal irinotecan (nal-IRI). EXPERIMENTAL DESIGN Mouse plasma and tissue pharmacokinetics of nal-IRI and the current clinical formulation of irinotecan were characterized. In vivo activity of irinotecan and nal-IRI was compared in xenograft models (3 each in nu/nu mice) of Ewing...

Objective(s): Hydrogen sulfide (H2S) attenuates ischemia-reperfusion injury (IRI) in different organs. However, its mechanism of action in renal IRI remains unclear. The present study investigated the hypothesis that H2S attenuates renal IRI via the induction of heat shock proteins (HSPs).Materials and Methods: Adult Wistar rats were subjected to unilateral renal ischemia for 45 min followed by...

Background Oxidative stress (OS), the production of free oxygen radicals caused by for instance renal ischemia/reperfusion injury (IRI), results in age associated diseases and accelerated aging. We have shown that preoperative fasting in young-lean C57BL6 male mice protects against renal IRI [1]. Since human patients are usually older and suffer from (co)morbidities, we investigated the effects...

BACKGROUND Renal ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury and a frequent occurrence in critically ill patients. Renal IRI releases proinflammatory cytokines within the kidney that induce crosstalk between the kidney and other organ systems. Atrial natriuretic peptide (ANP) has anti-inflammatory as well as natriuretic effects and serves important functions as a ...
