Liver fibrosis is the main predictor of the progression of chronic hepatitis C, and its assessment by liver biopsy (LB) can help determine therapy. However, biopsy is an invasive procedure with several limitations. A new, noninvasive medical device based on transient elastography has been designed to measure liver stiffness. The aim of this study was to(More)
BACKGROUND/AIMS Periodic endoscopic screening for oesophageal varices is recommended in patients with cirrhosis, but might be limited to a subgroup of patients if a simple non-invasive test was available to select those at risk of bleeding. METHODS We studied in 165 patients with cirrhosis the relation between the presence of oesophageal varices assessed(More)
In this paper, we develop a handwritten numeral recognition using multiwavelets and neural networks. We first transform the character image into polar coordinate ( ) θ , r using the center of mass of the character as origin, then by performing the Fourier transform, characters spectrum achieved; afterward the multi-wavelet transformation is applied to get(More)
Most clinical studies suggest that the prevalence and severity of liver steatosis are higher in patients infected with hepatitis C virus (HCV) genotype 3 than in patients infected with other genotypes. This may reflect the diversity and specific intrinsic properties of genotype 3 virus proteins. We analyzed the possible association of particular residues of(More)
A simple analysis of the learners' academic status at different levels of education shows that these learners have poor performance in probability and statistics subject. Also they have negative attitude to this subject. According to some researchers, teachers' attitude and their inappropriate method of teaching are among the most important factors in(More)
Chronic liver diseases complications generally occur when fibrosis progresses to cirrhosis. It is recognised that some patients do not progress while others develop significant fibrosis. Factors influencing the fibrosis progression rate are especially studied in chronic hepatitis C. Among many identified factors, the most important are those warranted a(More)
