Recent emerging technologies such as internetworking and the World Wide Web (WWW) have signiicantly expanded the types, availability, and volume of data accessible to an information management system. In this new environment it is imperative to view an information source at the level of its relevant semantic concepts. We propose that these semantic concepts(More)
Diverticular disease is one of the most prevalent medical conditions to affect Western populations. Symptomatic diverticular disease can range from mild, low-level symptomatology similar to that seen in irritable bowel syndrome to acute bouts of diverticulitis complicated by abscess or frank perforation. This review discusses the epidemiology,(More)
BACKGROUND Altered small intestinal motility in cirrhotics may play a major role in the development of bacterial translocation (BT) by leading to small intestinal bacterial overgrowth. BT has been implicated in the development of several complications including spontaneous bacterial peritonitis, esophageal variceal hemorrhage, and hepatorenal syndrome.(More)
BACKGROUND Historical ambulatory pH monitoring systems for the evaluation of gastroesophageal reflux disease have been catheter based and uncomfortable for patients, commonly limiting both their diet and activities. Catheter-based studies have also been reported to underestimate the amount of reflux a patient may have in a normal, routine day. Compared with(More)
Modulation of intestinal flora through the use of probiotics is an emerging therapeutic strategy in the management of chronic liver diseases. This article focuses on the pathophysiologic basis for using probiotics in liver disease and reviews the existing literature on the subject. The role of probiotics is examined in the following areas: a) prevention of(More)
The World Wide Web is fast becoming a ubiquitous computing environment Prevalent keyword based search techniques are scalable but are incapable of accessing information based on concepts We investigate the use of concepts from multiple real world pre existing domain ontologies to describe the underlying data content and support information access at a(More)
Diverticular disease is one of the most common medical conditions affecting Western populations. Inflammatory complications are the most common manifestation of the disease and typically cause acute bouts of abdominal pain and fever. Chronic symptoms can also occur and can be mistakenly attributed to irritable bowel syndrome and rarely to inflammatory bowel(More)
Workkow management is primarily concerned with dependencies between the tasks of a workkow, to ensure correct control ow and data ow. Transaction management, on the other hand, is concerned with preserving data dependencies by preventing execution of connicting operations from multiple, concurrently executing tasks or transactions. In this paper we argue(More)
Workkows are composite activities that can be used to support and automate multisystem applications involving humans, heterogeneous databases and legacy systems. The traditional atomic transaction model, successful for centralized and homogeneous applications, is not suitable for supporting such workkows. Intertask dependencies, which are conditions(More)
