A total of 89 patients with alcoholic cirrhosis and 40 healthy subjects were included in a study to assess the prevalence of intestinal bacterial overgrowth and to analyze its relationship with the severity of liver dysfunction, presence of ascites, and development of spontaneous bacterial peritonitis (SBP). Bacterial overgrowth was measured by means of a(More)
This article presents a semantic-based Web retrieval system that is capable of retrieving the Web pages that are conceptually related to the implicit concepts of the query. The concept of “concept” is managed from a fuzzy point of view by means of semantic areas. In this context, the proposed system improves most search engines that are based on matching(More)
This paper presents an application of diverse soft-computing techniques to adaptive traffic light controls. The proposed methodology consists of two main phases: off-line and on-line. First, clustering techniques and optimization methods are used at the off-line stage to discover the prototypes which characterize the traffic mobility patterns at an(More)
To the Editor: In the October 1989 issue of Digestive Diseases and Sciences, Alberti et al (1) reported the results obtained studying the levels of soluble interleukin-2 receptors (slL-2R) in sera from patients with acute and chronic viral hepatitis. Increased slL-2R levels were detected in the early phase of acute hepatitis type B. Among patients with(More)
Bacterial translocation (BT) has been involved in the pathogenesis of spontaneous bacterial peritonitis (SBP) in experimental cirrhosis. Because malnutrition is a common feature in cirrhosis, the aim of this study was to evaluate the effect of nutrition on BT and SBP. We induced cirrhosis in 44 Sprague-Dawley rats by administration of oral CCl4, and,(More)
