BACKGROUND & AIMS Statins improve hepatic endothelial function and liver fibrosis in experimental models of cirrhosis, thus they have been proposed as therapeutic options to ameliorate portal hypertension syndrome. The transcription factor Kruppel-like factor 2 (KLF2) may be induced by statins in liver sinusoidal endothelial cells (SEC), orchestrating an(More)
BACKGROUND & AIMS Liver grafts obtained from healthy rat donors develop acute microcirculatory dysfunction due to cold-storage and warm-reperfusion injuries. These detrimental effects are avoided adding simvastatin to the cold-storage solution. Considering the importance of increasing organ donor pool for transplantation, we characterized whether(More)
INTRODUCTION Autophagy is a cellular process essential for survival and homeostasis that confers cellular protection toward a wide range of deleterious stimuli. It has a highly complex regulation with several autophagic proteins also belonging to other main signaling pathways as cell proliferation or apoptosis. In addition, autophagy has an important role(More)
UNLABELLED Endothelial dysfunction drives vascular derangement and organ failure associated with sepsis. However, the consequences of sepsis on liver sinusoidal endothelial function are largely unknown. Statins might improve microvascular dysfunction in sepsis. The present study explores liver vascular abnormalities and the effects of statins in a rat model(More)
Warm ischemia and reperfusion (WIR) causes hepatic damage and may lead to liver failure, however the mechanisms involved are largely unknown. Here we have characterized the microcirculatory status and endothelial phenotype of livers undergoing WIR, and evaluated the use of simvastatin in WIR injury prevention. Male Wistar rats received simvastatin, or(More)
Hepatic microcirculatory dysfunction due to cold storage and warm reperfusion (CS+WR) injury during liver transplantation is partly mediated by oxidative stress and may lead to graft dysfunction. This is especially relevant when steatotic donors are considered. Using primary cultured liver sinusoidal endothelial cells (LSECs), liver grafts from healthy and(More)
Insecticidal dipping fluid emulsions, mixed in vitro in dam water containing suspended clay particles and 1% w/v zinc sulphate, were analysed to determine rates of settling of diazinon, cyhalothrin and cypermethrin. Fifteen minutes after mixing, the concentration of the insecticides 5 cm below the surface had declined by 72.5%, 72.8% and 89.4%,(More)
Hepatic stellate cells (HSC) play a key role in the development of chronic liver disease (CLD). Liraglutide, well-established in type 2 diabetes, showed anti-inflammatory and anti-oxidant properties. We evaluated the effects of liraglutide on HSC phenotype and hepatic microvascular function using diverse pre-clinical models of CLD. Human and rat HSC were in(More)
