OBJECTIVES To assess the prevalence and significance of HCV infection in patients with chronic active hepatitis B. METHODS We studied clinical and histological activity in 132 patients with chronic active hepatitis B, 17 of whom were co-infected by HCV. Serum HBV-DNA was determined by dot-blot hybridization and polymerase chain reaction (PCR) and serum(More)
The aim of this study was to assess the implications of dual infection with hepatitis B virus (HBV) and hepatitis C virus (HCV). The HBV and HCV status in 100 patients with chronic hepatitis was analysed. HBV DNA was studied using liquid hybridization and the polymerase chain reaction (PCR). HCV viremia was measured using qualitative and quantitative PCR.(More)
We studied a 62 year-old woman with a clinical phenotype characterized by encephalopathy, restrictive cardiomyopathy, and prominent intestinal pseudo-obstruction. Muscle morphology showed ragged red fibres with ultrastructurally abnormal mitochondrial whereas muscle respiratory chain was normal. Molecular genetics revealed the 'common deletion' in mtDNA,(More)
Evidence suggests that cognitive deficits are a core feature of schizophrenia. The concept of "cognitive dysmetria" has been introduced to characterize disintegration of fronto-thalamic-cerebellar circuitry which constitutes a key network for a variety of neuropsychological symptoms in schizophrenia. The present multimodal study aimed at investigating(More)
Natural killer (NK) cell activity against K562 cell line, and interleukin-2 (IL-2) activity in supernatants from lectin-activated PBMC cultures from 17 patients with acute hepatitis B in the early phase of illness were studied. These patients showed enhanced NK cytotoxicity and higher levels of IL2 activity as compared with control subjects. There was a(More)
Complete understanding of the mechanisms that coordinate work and energy supply of the brain, the so called neurovascular coupling, is fundamental to interpreting brain energetics and their influence on neuronal coding strategies, but also to interpreting signals obtained from brain imaging techniques such as functional magnetic resonance imaging.(More)
Interventional studies suggest that changes in physical fitness affect brain function and structure. We studied the influence of high intensity physical exercise on hippocampal volume and metabolism in 17 young healthy male adults during a 6-week exercise program compared with matched controls. We further aimed to relate these changes to hypothesized(More)
OBJECTIVES Factors that determine the severity of hepatitis C virus (HCV)-recurrent disease in patients undergoing orthotopic liver transplantation (OLT) for HCV cirrhosis have not been clearly identified. To address this issue, we evaluated the histological and virological outcome in 25 patients who underwent OLT for HCV cirrhosis. METHODS HCV-RNA was(More)
BACKGROUND The dysfunction of specific brain areas might account for the distortion of body image in patients with anorexia nervosa. The present study was designed to reveal brain regions that are abnormal in structure and function in patients with this disorder. We hypothesized, based on brain areas of altered activity in patients with anorexia nervosa and(More)
The aim of this study is to determine the origin, clinical outcome, allograft histological characteristics, and virological outcome of de novo hepatitis B virus (HBV) infection after orthotopic liver transplantation (OLT). We studied 136 hepatitis B surface antigen (HBsAg)-negative liver transplant recipients. HBV DNA was detected by dot-blot hybridization(More)
