Hepatic ischemia/reperfusion injury has so far been investigated in various experimental models. A clinical transfer of experimental results is, however, problematic because of anatomical and physiological differences and also the inevitable simplification of experimental work. The choice of model must therefore be adapted to the clinical question to be(More)
BACKGROUND Vascular occlusion to prevent haemorrhage during liver resection causes ischaemia-reperfusion (IR) injury. Insights into the mechanisms of IR injury gathered from experimental models have contributed to the development of therapeutic approaches, some of which have already been tested in randomized clinical trials. METHODS The review was based(More)
BACKGROUND The shortage of organ donors has led to the introduction of the Eurotransplant Senior Program (ESP) to optimize the allocation of kidneys from elderly donors by age-matching. In the face of a rapidly aging population, identification of prognostic factors for kidney allograft survival within the ESP population will be of enormous significance. (More)
BACKGROUND Preservation injury is a main factor leading to graft failure in liver transplantation. The aim of the study was to minimize preservation injury by modifications of the histidine-tryptophan-ketoglutarate (HTK) solution (incorporation of N-acetyl-histidine, aspartate, glycine, alanine, and arginine). MATERIALS AND METHODS The study was carried(More)
This study investigates the impact of rat strain on the development of nonalcoholic fatty liver disease (NAFLD) focusing on morphological features and microcirculation. Male rats of Lewis, Wistar, and Sprague Dawley (n = 6 per strain and group) were randomized into a high-fat group which was fed with a special high-fat nutrition for a 3-week period and a(More)
BACKGROUND Hepatocellular carcinoma (HCC) represents the main cause of death among patients with cirrhotic liver disease, but little is known about mechanisms of cirrhosis associated carcinogenesis. We investigated the diagnostic impact of microRNA-200 (miR-200) family members as important epigenetic regulators of epithelial-mesenchymal transition (EMT) to(More)
BACKGROUND Because of its immunomodulatory action, the protease bromelain represents a novel strategy for the treatment of hepatic ischemia/reperfusion (I/R) injury. A dose-response study was performed to investigate the effect of bromelain on liver function, microcirculation, and leukocyte-endothelium interactions in hepatic I/R injury. MATERIALS AND(More)
OBJECTIVE Simulation training improves laparoscopic performance. Laparoscopic basic skills can be learned in simulators as box- or virtual-reality (VR) trainers. However, there is no clear recommendation for either box or VR trainers as the most appropriate tool for the transfer of acquired laparoscopic basic skills into a surgical procedure. DESIGN Both(More)
The purpose of our study was to develop suitable methods to quantify oxidative DNA lesions in the setting of transition metal-related diseases. Transition metal-driven Fenton reactions constitute an important endogenous source of reactive oxygen species (ROS). In genetic diseases with accumulation of transition metal ions, excessive ROS production causes(More)
The remarkable capacity of the liver to regenerate after injury and the prospects of organ self-renewal have attracted much interest in the understanding and modulation of the underlying molecular events. We investigated the effect of mammalian target of rapamycin (mTOR) inhibitor rapamycin (RAPA) on liver by correlating intravital microscopy,(More)
