The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.
Pancreatic Cancer has been and still is one of the deadliest types of human malignancies. The annual mortality rates almost equal incidence rates making this disease virtually universally fatal. The 5-year survival of patients with pancreatic cancer is a dismal 5% or less. Therapeutic strategies are extremely limited with gemcitabine extending the survival by a disappointing few weeks. The failure of several randomized clinical trials in the past decade investigating the therapeutic efficacy of different mono- and combination therapies reflects our limited knowledge of pancreatic cancer biology. In addition, biomarkers for early detection are sorely missing. Several pancreatic cancer risk fa...
This Research Topic eBook includes articles from Volume I and II of The Future of Physiology: 2020 and Beyond series: Research Topic “The Future of Physiology: 2020 and Beyond, Volume I” Research Topic “The Future of Physiology: 2020 and Beyond, Volume II” The term Physiology was introduced in the 16th century by Jean Francois Fernel to describe the study of the normal function of the body as opposed to pathology, the study of disease. Over the ensuing centuries, the concept of physiology has evolved and a central tenet that unites all the various sub-disciplines of physiology has emerged: the quest to understand how the various components of an organism from the sub-cellular and cel...
This book provides an evidence-based approach to the diagnosis and surgical management of the diseases of the pancreas and biliary tree, highlighting the most recent findings. The chapters are designed to accompany the reader on a step-by-step approach to the patient, providing the latest evidence to justify each recommendation. Wherever feasible and indicated, emphasis is placed on the use of tables and algorithms to simplify decision-making. The information contained in this well-referenced book is thus relevant not only to practicing pancreatobiliary and general surgeons, but also offers valuable guidance for surgical trainees. This book covers 14 diseases of the pancreas and biliary tree, from the more common gallstones and common bile duct stones, acute and chronic pancreatitis, to more complex benign conditions such as biliary fistulae and strictures, as well as cystic tumors of the pancreas, and finally the major malignancies include gallbladder cancer, pancreatic cancer and hilar cholangiocarcinoma.
Clinical Pancreatology Since the book Clinical Pancreatology for Practising Gastroenterologists and Surgeons was first published sixteen years ago, the knowledge and clinical management of pancreatic diseases have developed markedly. Thanks to the development of the translational research and the from bench to bedside concept, much progress from the lab has been applied to clinical practice. In addition, several highly relevant clinical trials published over the last years have resulted in the update and optimisation of clinical guidelines. A new and validated classification of severity and complications of acute pancreatitis is firmly rooted in clinical practice and has been the basis for t...
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
The encyclopedic guide to the pancreas for practicing clinicians and surgeons In the past decade extraordinary developments in diagnostic and therapeutic radiology and endoscopy have been coupled with major advances in surgical techniques and basic sciences. As a result the management of pancreatic disorders is now handled by a multidisciplinary team. This book shows you how to achieve superior patient management by taking the team approach to in-hospital care. Fully revised and updated, this new edition of The Pancreas: An Integrated Textbook of Basic Science, Medicine and Surgery details the latest knowledge on genetics and molecular biological background in terms of anatomy, physiology, p...
