The field of gastrointestinal biology has been transformed by an explosion of knowledge for gastrointestinal motility, absorption, and secretion. The chapters in this book summarise the methods of molecular biology and the cell biology of gut enzymes, secreting cells and cells that respond to these enzymes. This book is a valuable reference for students, researchers and faculties of gastrointestinal motility, absorption and secretion. No other single source covers this field so comprehensively. It contains a considerable amount of detail on subjects such as gut hormones, gut malabsorption, alcohol toxicity on the stomach and methods used in physiologic study of the digestive tract. Disease conditions are discussed only to the extent that they illustrate physiologic mechanisms. It is difficult for such a comprehensive work to remain up to date for very long, considering how rapidly our knowledge of life sciences expands. This book, a comprehensive treatise on the causes, diagnosis, and management of gastrointestinal-motility disorders, consists of eighteen chapters with extensive references contained in slightly fewer than 300 pages. It achieves its goal through generally lucid writing and the overlap of information from chapter to chapter commonly observed in multi-authored works. Therefore, the reader is best advised to go through this book in a relaxed manner; this will allow them to finish it in a relatively short amount of time and appreciate the field of gastrointestinal motility, particularly current practices and research methods for solving its many riddles. All the chapters are clearly written, but the target audience seems to vary from medical students to practicing gastroenterologists. Despite these drawbacks, gastroenterologists, surgeons, and basic scientists wishing to bring their general knowledge of clinical motility disorders up to date will find this book useful.

Over the past few years, epidemiological studies have revealed that there is an increase of life threatening liver diseases worldwide. It becomes increasingly clear that developments in this field are moving so rapidly toward the creation of new drugs against these maladies. Numerous research articles and books have been published on various aspects of toxicities, symptoms, managements and health implications of the liver. Consequently, a catalogue of collective information of toxicities, various features of natural products, and remedies for the prevention of toxicities is needed. This book deals with the toxicities in organs like the liver and the role natural products have in the preventing these ailments. It also analyses trends in the processing of natural products by using nanotechnology and their health implications. The main purpose of this book is to exhibit relevant, modern information on hepatotoxicity, its symptoms, and treatments presented by internationally recognised experts in the field. Therefore, it is our belief that this book has covered some of the most interesting aspects of research in liver diseases and provides a trustworthy source of current information in this area of research which should prove useful to the scientists interested in this discipline throughout the world. This collection will interest a variety of other scientific disciplines including toxicology, genetics, medicine and pharmacology, as well as drug and food sciences. We hope that our readers will find this volume to be a delightful addition to their personal libraries, laboratories and offices. Additionally, it can be used as a required or recommended text for related courses taught at colleges and universities levels.
