BACKGROUND The models for end-stage liver disease (MELD) and serum sodium (SNa) are important prognostic markers in cirrhosis. A novel index, MELD to SNa ratio (MESO), was developed to amplify the opposing effect of MELD and SNa on outcome prediction. METHODS A total of 213 cirrhotic patients undergoing hepatic venous pressure gradient (HVPG) measurement(More)
Recent studies have shown that the activated endocannabinoid system participates in the increase in IHR (intrahepatic resistance) in cirrhosis. The increased hepatic production of vasoconstrictive eicosanoids is involved in the effect of endocannabinoids on the hepatic microcirculation in cirrhosis; however, the mechanisms of these effects are still(More)
Portopulmonary hypertension is a recognized but uncommon complication of cirrhosis. Liver transplantation may be contraindicated in patients with severe portopulmonary hypertension. In order to decrease the pulmonary arterial pressure, intravenous administration of epoprostenol has been shown to provide substantial beneficial results in these patients.(More)
BACKGROUND/AIMS Increased intrahepatic resistance (IHR) in cirrhosis is due to fibrosis and hepatic endothelial dysfunction (HED). Besides producing fibrosis, increased reactive oxygen species (ROS) promotes ROS-related nitration of anti-oxidative enzymes in cirrhotic livers. Tyrosine nitration (nitrotyrosilation)-related inactivation of anti-oxidative(More)
BACKGROUND The model for end-stage liver disease (MELD), hepatic venous pressure gradient (HVPG), and serum sodium (SNa) are important prognostic markers for patients with liver cirrhosis. The correlation among these markers and their predictive accuracy for survival are unclear. METHODS A total of 213 cirrhotic patients undergoing hemodynamic measurement(More)
BACKGROUND Honokiol, a small active molecular compound extracted from magnolia, has recently been shown to inhibit hepatitis C virus (HCV) infection in vitro. AIMS This study further characterized aspects of the HCV lifecycle affected by the antiviral functions of honokiol. METHODS The influence of honokiol on HCV infection, entry, translation and(More)
Increased oxidative stress is involved in the development of portal hypertension in cirrhosis. Our study aimed to assess the relationship between oxidative stress and hemodynamic parameters in cirrhotic patients. Forty-two patients with viral cirrhosis and 24 normal controls were enrolled. Measurements of plasma levels of malondialdehyde (MDA),(More)
BACKGROUND/AIM Anandamide can activate potassium (K(+)) channels to induce an endothelium-dependent vasorelaxation in normal rat mesenteric arteries. Cannabinoids contribute partly to the splanchnic vasodilation in cirrhosis. This study investigated the roles of vascular K(+) channels in anandamide-induced mesenteric vasorelaxation in isolated rat cirrhotic(More)
Cannabinoids have been reported to participate in the pathogenesis of peripheral vasodilatation in cirrhosis. However, their roles in increased intrahepatic resistance (IHR) in cirrhotic livers are unknown. We aimed to investigate the effects of cannabinoids in the hepatic microcirculation of cirrhotic rats produced by bile duct ligation. In isolated liver(More)
Gastropericardial fistula is generally associated with benign gastric diseases and is an uncommon complication of gastric adenocarcinoma. Pericarditis and cardiac tamponade are the ultimate outcome, with extremely high mortality rates. We report a 47-year-old man with gastric adenocarcinoma who had completed radiotherapy and was on scheduled chemotherapy,(More)
