Bile Acids in Gastroenterology: Basic and Clinical Advances


Book Description

This book contains the proceedings of the XIIIth International Bile Acid Meeting (Falk Symposium 80), an official satellite meeting of the World Congress of Gastroenterology, held in San Diego, California, U.S.A., September 30--October 2, 1994. It begins with presentations of major advances in bile acid chemistry, biology and pharmacology. The new structure proposed for the mixed micelles present in bile is reviewed, as are the properties of new synthetic analogues of bile acids. The mechanisms by which bile acids interact with cell membranes are discussed in order to provide insight into the hepatotoxic effects of bile acids in cholestatic liver disease. The book further shows the exciting progress in the molecular biology of bile acid transport by the hepatocyte and enterocyte, and concludes with a consensus on the use of ursodeoxycholic acid in cholestatic liver disease and as an adjunct to immunosuppressive therapy after liver transplantation, and to interferon therapy in chronic viral hepatitis.

Subsequent chapters focus on diseases involving bile acid abnormalities, and specific applications are addressed concerning gallstones, cholestatic liver disease, NAFLD/NASH, hepatitis, pancreatitis, esophageal cancer and colon cancer. In keeping with the book’s integrated approach, the Editor has gathered a broad range of eminent scholars and practitioners to provide a comprehensive review of modern bile acid research. The book offers clinical physicians, basic researchers and postgraduate students essential insights into cutting-edge research and paves the way for further research.




Bile Acids - Cholestasis - Gallstones


Book Description

This volume, the proceedings of the Falk Symposium No. 84 held in Berlin, Germany, June 8-10, 1995, deals with three important topics in gastroenterology: the basics of bile acid and the phospholipid mechanism, the diagnosis and therapy of gall bladder and bile duct stones, and the treatment of chronic liver diseases. The contributors have all made major contributions to the investigation of these areas and therefore present first-hand information on the latest developments. Audience: This book is a state of the art update on both basic science and clinical aspects of bile acids, for all researchers and clinicians involved in the area.




Workshops in Bile Acid Research


Book Description

During the 7th International Bile Acid meeting held in Cortina d'Ampezzo. , Italy, during March 1982, there were two important Workshops dealing with recent advances in two areas of bile acid metabolism - Serum Bile Acids i,n Health and Disease and The Pathophysiology of the Enterohepatic Circulation. These Workshops complemented the broad range of topics in bile acid metabolism which were presented formally as part of a Postgraduate Course. The proceedings of these formal presentations have already been pub lished by MTP Press under the title Bile Acids in Gastroenterology but in view of the exciting, important, new information which emerged during both Workshops, the organisers of the meeting felt that it would be valuable to record and edit the proceedings of the Work shops, which form the basis of this volume. The advent of new techniques for measurement of total and indi vidual bile acids in serum now means that accurate and reliable 7 PREFACE measurements of bile acids in peripheral circulation are available to all. This has resulted in a veritable explosion of information in the serum bile acid field and, therefore, the appearance of a critical evalu ation of the technical and basic scientific and clinical aspects of measuring serum bile acids is indeed timely.




Bile Acids and Hepatobiliary Diseases - Basic Research and Clinical Application


Book Description

Since the last International Bile Acid Meeting in San Diego in 1994, new advances have been made in the understanding of bile acid metabolism and transport. The cytotoxic as well as the therapeutic effects of specific bile acids have been further explored and the beneficial effects of ursodeoxycholic acid in various chronic cholestatic conditions have been substantiated. Much basic and clinical research has been conducted to unravel the underlying mechanisms of action. This volume, the proceedings of Falk Symposium No. 93 (XIV International Bile Acid Meeting), held in Freiburg-im-Breisgau, Germany, October 22-24, 1996, is dedicated to both basic and clinical aspects of bile acid research related to the role of bile acids in hepatobiliary diseases.




The Bile Acids: Chemistry, Physiology, and Metabolism


Book Description

Over a decade has elapsed since the last volume in this series was published. At that time we considered that we had comprehensively covered all aspects relating to bile acid chemistry and physiology. However, major strides have been made in our understanding of the physiology and pathophysiology of bile acids, due largely to the great advances which have taken place in analytical technology. As a result, the need to document these advances was felt acutely, and therefore this volume is devoted to methodologies in bile acid analysis and their applications. This volume includes twelve chapters written by prominent scientists in the field of bile acid research. The initial chapter discusses techniques of extraction and isolation of bile acids from biological fluids. It is followed by descriptions of physical methods of analysis and discussions of the way these techniques have been applied in the field of bile acid research. Of practical value is the inclusion of a comprehensive list of spectra obtained for refer ences by nuclear magnetic resonance spectroscopy and mass spectrometry . These chapters are followed by reviews of biological methods of immuno assay and bioluminescence. Specific applications of these techniques are then addressed in contributions relating to bile acid analysis of tissue, serum, urine, and feces. With this integrated approach we have attempted to provide a volume which represents a comprehensive review of the analytical field of bile acids, while also serving as a useful reference book for those workers involved in bile acid analysis.




Bile Acids in Gastroenterology


Book Description

Over the past 10 years there has been a veritable explosion of knowledge in working in this area are fortunate to meet their bile acid research. Those colleagues from time to time at International Meetings which are often held in attractive parts of the world. The 7th International Symposium on bile acids 'Bile Acids in Gastroenterology' was no exception. It took place in Cortina d'Ampezzo in the heart of the Italian Dolomites, from 17th-20th March 1982. This meeting was organised by a Scientific Committee, with representatives from Italy, the United States and Great Britain, in collaboration with the Italian Society of Gastroenterology. The format of the meeting was somewhat different from that of previous years. In addition to the free communications (verbal and poster presentations) which characte rise many scientific meetings, there was also an Advanced Postgraduate Course on bile acids given by a distinguished international panel of experts. Their contributions form the basis for this timely volume which should be of interest both to basic scientists and to clinical investigators alike. The editors are indebted to Dr Gian Germano Giuliani, Gipharmex SpA, Milano, whose generous support made the meeting possible. They also thank Mr P. M. Lister, Managing Editor, MTP Press Limited and Mrs Veronica Cesari, Italian Society of Gastroenterology for help with the publication of these proceedings. R.

Biology of Bile Acids in Health and Disease


Book Description

Beginning in 1970, the International Bile Acid Meeting has taken place every two years and each time new progress in our understanding of the complex role of bile acids in many metabolic processes of the liver and the intestine has been revealed by a selected group of leading scientists from all over the world. Although originally mainly physiological data on bile acid synthesis and transport were emphasized, and later on also the therapeutic benefit of bile acids in gallstone disease and cholestasis was discovered, we have come now to the molecular biology and genetic era with major discoveries in transport defects and related diseases. This book is the proceedings of Falk Symposium No. 120, held in The Hague, The Netherlands, on October 12-13, 2000 - the 16th International Bile Acid Meeting. One of the main discoveries recently has been the identification of nuclear receptors for bile acids, which gives them a much broader perspective than previously anticipated. It even suggests that bile acids can regulate their biosynthesis and enterohepatic circulation transcriptionally. It will therefore not be surprising that this topic, together with the molecular regulation of cholesterol 7alpha-hydroxylase and cholesterol homeostasis, has a dominant place in these proceedings. Another important topic is the progress in our molecular understanding of hepatic (both at the basolateral and canalicular sites), cholangiocytic and intestinal bile acid transport processes. Further insights into genetic defects causing cholestasis or intestinal malabsorption in animal models and in human diseases are also discussed by a number of well-known authors. Finally the last section deals with new findings on the role of bile acid therapy in cholestatic syndromes or chemoprevention and with the potential benefit of bile acid inhibitors. All contributors provide an update on the most recent developments in their field.
