Background: Apoptosis may be an important mechanism of hepatocyte death in chronic viral liver disease. Methods: We studied apoptosis in liver biopsies from 30 patients with chronic viral hepatitis and 8 patients with viral cirrhosis by the TUNEL method. 12 cases of non-alcoholic steatohepatitis and 12 cases of primary biliary cirrhosis were used as(More)
—The correct identification of the intima-media thickness (IMT) of the common carotid artery (CCA) walls has a high clinical relevance as it represents one of the most reliable predictor for future cardiovascular events. In this work we propose and evaluate an integrated system for the segmentation of the intima-media complex (IMC) and the lumen diameter in(More)
It is well known that the blood oxygen level-dependent (BOLD) signal measured by functional magnetic resonance imaging (fMRI) is influenced-in addition to neuronal activity-by fluctuations in physiological signals, including arterial CO2, respiration and heart rate/heart rate variability (HR/HRV). Even spontaneous fluctuations of the aforementioned(More)
