Lipid peroxidation (LPO) product accumulation in human tissues is a major cause of tissular and cellular dysfunction that plays a major role in ageing and most age-related and oxidative stress-related diseases. The current evidence for the implication of LPO in pathological processes is discussed in this review. New data and literature review are provided(More)
UNLABELLED New-onset diabetes is a common complication after liver transplantation. AIM We aimed to analyze the incidence and rate of known risk factors and the impact of new-onset diabetes mellitus on postoperative outcome. METHODS We retrospectively evaluated the files of 310 patients who underwent liver transplantation between 1995 and 2009.(More)
IL-6 is a cytokine with pleiotropic biological functions, including induction of the hepatic acute phase response and differentiation of activated B cells into Ig-secreting plasma cells. We found that human peripheral blood monocytes express the IL-6-R, which is undetectable on the large majority of lymphocytes of healthy individuals. Stimulation of(More)
BACKGROUND Our previous results showed that hepatitis C virus (HCV) is detectable on erythrocytes by RT in situ PCR. The aims of the present study were to compare the sensitivity of this erythrocyte in situ PCR to routine serum solution phase HCV PCR as well as to obtain more data about the binding and cellular localization of HCV in the erythrocyte.

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide. Primary hepatocellular carcinoma can be found most frequently (80-90 %) in patients with liver cirrhosis. The most frequent causes of liver cirrhosis are chronic hepatitis B and C virus infections and chronic alcohol consumption. The occurrence of hepatocellular(More)
UNLABELLED The ability to predict which patients are most likely to achieve a sustained virologic response (SVR) with peginterferon/ribavirin would be useful in optimizing treatment for hepatitis C virus (HCV). The objective of this large international noninterventional cohort study was to investigate the predictive value (PV) of a virologic response (VR)(More)
BACKGROUND In a cross-sectional study we studied the fasting serum DPP-4 enzymatic activity (sDPP-4) and the insulin resistance index (HOMA2-IR) in gliptin naïve patients with type 2 diabetes and in non-alcoholic fatty liver disease (NAFLD) and in healthy controls (CNTRL). METHODS AND FINDINGS sDPP-4 was measured by kinetic assay in 39 NAFLD (F/M:19/20,(More)
Human blood monocytes normally express the interleukin-6 receptor. Treatment of cultured monocytes with endotoxin, interleukin-1 beta, or interleukin-6 results in a decrease in interleukin-6 receptor mRNA levels. Glucocorticoids aso cause a drop in monocytic interleukin-6 receptor mRNA levels. We also found interleukin-6 receptor expression in cultured(More)
In chronic liver diseases caused by oxidative stress (alcoholic and non-alcoholic fatty liver diseases, drug- and chemical-induced hepatic toxicity), the antioxidant medicines such as silymarin can have beneficial effect. Liver cirrhosis, non-alcoholic fatty liver and steatohepatitis are risk factors for hepatocellular carcinoma (HCC). Insulin resistance(More)
Oxidative stress plays an important role in the pathogenesis of toxic liver diseases and of other hepatic alterations. We summarize the pathomechanism of free radical reactions in liver diseases and the results of experimental and clinical observations. Most of the hepatoprotective drugs belong in the group of free-radical scavengers, their mechanism of(More)
