PRE-PUBLICATION ENDORSEMENTS: "Physiology of the Gastrointestinal Tract has been the benchmark text related to this specific topic for years, yet the last (third) edition was published more than a decade ago. During this period there have been many discoveries in GI pathobiology and, simultaneously, a recognition that this organ system is an elegant one for basic molecular discovery. That a relatively recent issue of Science was completely devoted to alimentary tract biology, speaks to this previous point. Thus the newly minted fourth edition of this work comes at an auspicious time. It does not disappoint. Basic chapters on physiology and growth are outstanding; examples being new contributions focused on the Wnt/Catenin and Notch pathways. Chapters are authored by leaders in the subfields, are clearly written, scientifically rigorous, and tend toward the comprehensive. This work imparts the flavor of organ function but does so by building up basic understanding such that it culminates in a more holistic picture; doing so based on science, not simply phenomena. This new edition is a delight and represents a critical resource for all serious students of the alimentary tract." -James L. Madara, M.D., Dean, Division of Biological Sciences and the Pritzker School of Medicine University; Vice-President for Medical Affairs, The University of Chicago The table of contents of the fourth edition of the Physiology of the Gastrointestinal Tract is impressive, and brings together a wide range of true experts in their fields. The chapters are authoritative and up to date. There has been a real attempt to cover the entire field of GI Physiology. There is no other text that currently offers this degree of depth of coverage with monographs by leaders in their fields. This will be a wonderful resource for investigators in GI Physiology and for those educators who teach that subject." -David H. Alpers, MD, William B.
