Membrane Transport Processes In Organized Systems

Membrane Transport Processes in Organized Systems is a softcover book containing portions of Physiology of Membrane Disorders (Second Edition). The parent volume contains six major sections. This text encompasses the fourth and fifth sections: Transport Events in Single Cells and Transport in Epithelia: Vectorial Transport through Parallel Arrays. We hope that this smaller volume, which deals with transport processes in single cells and in organized epithelia, will be helpful to individuals interested in general physiology, transport in single cells and epithelia, and the methods for studying those transport processes. THOMAS E. ANDREOLI JOSEPH F. HOFFMAN DARRELL D. FANESTIL STANLEY G. SCHULTZ Vll Preface to the Second Edition The second edition of Physiology of Membrane Disorders represents an extensive revision and a considerable expansion ofthe first edition . Yet the purpose of the second edition is identical to that of its predecessor, namely, to provide a rational analysis of membrane transport processes in individual membranes, cells, tissues, and organs, which in tum serves as a frame of reference for rationalizing disorders in which derangements of membrane transport processes play a cardinal role in the clinical expression of disease. As in the first edition, this book is divided into a number of individual, but closely related, sections. Part V represents a new section where the problem of transport across epithelia is treated in some detail. Finally, Part VI, which analyzes clinical derangements, has been enlarged appreciably.

With the recent changes in the health care industry, surgeons face increasing pressure to devote their time to their clinical activities, thus limiting their research efforts. It is essential that young and creative individuals are encouraged to perform research and are given incentives to participate in research under the mentorship of more experienced research investigators. Surgical Research is the first book to include all the information necessary for the surgical scientist to perform a research experiment. The editors have assembled outstanding, expert investigators in multiple surgical fields and asked them to describe how they achieve their research accomplishments. In Surgical Research, these experts in the field have outlined everything involved in preparing and conducting a research project. Some of the topics covered in the book include how to state a research question, how to review the available information, how to write research protocol, how to obtain grant money for the experiment, how to analyze the data, and how to present the findings. Also discussed are the ethics of animal and human experimentation along with the history and philosophy of surgical research. To continue to advance technologies and surgical methods, research must continually be performed. Potentially great discoveries are being missed because would-be researchers do not know where to start or how to conduct research, and therefore do not even try. This book provides prospective researchers with all the basic steps needed to perform a research experiment in the surgical field. No student, resident, or fellow should start a research project without this book and no senior surgical scientist should be without it occupying a prominent position in the library. Key Features * The first complete compendium detailing the process and procedures to perform surgical research * Provides details on and compares various methodologies * A "must have" resource for the surgical resident, fellow, or scientist * Includes a listing of resources and web sites to help the researcher even further

Focus, Organization, and Content This book, like the first edition, deals with the mass transport processes that take place in living systems, with a focus on the normal behavior of eukaryotic cells and the - ganisms they constitute, in their normal physiological environment. As a consequence of this focus, the structure and content of the book differ from those of traditional transport texts. We do not start with the engineering principles of mass transport (which are well presented elsewhere) and then seek biological applications of these principles; rather, we begin with the biological processes themselves, and then - velop the models and analytical tools that are needed to describe them. This approach has several consequences. First of all, it drives the content of the text in a direction distinctively different from conventional transport texts. This is - cause the tools and models needed to describe complex biological processes are often different from those employed to describe more well-characterized inanimate systems. Many biological processes must still be described phenomenologically, using me- odologies like nonequilibrium thermodynamics. Simple electrical analogs employing a paucity of parameters can be more useful for characterization and prediction than complex theories based on the behavior of more well-defined systems on a laboratory bench. By allowing the biology to drive the choice of analysis tools and models, the latter are consistently presented in the context of real biological systems, and analysis and biology are interwoven throughout.

Clinical Disorders of Membrane Transport Processes is a softcover book containing a portion of Physiology of Membrane Disorders (Second Edition). The parent volume contains six major sections that deal with general aspects of the physiology of transport processes and specific aspects of transport processes in cells and in organized cellular systems, namely epithelia. This text contains the last section, which deals with the application of the physiology of transport processes to the understanding of clinical disorders. We hope that this smaller volume will be helpful to individuals particularly interested in clinical derangements of membrane transport processes. THOMAS E. ANDREOLI JOSEPH F. HOFFMAN DARRELL D.

Amino acid transport is a part of each of two larger subjects, amino acid metabolism and the biomembrane transport of various . small molecules and ions. Nevertheless in this volume we treat amino acid transport as more than a fragment of either of these two larger subjects. A more comprehensive approach is justified when we remember two historic and ongoing aspects of the title subject. First, amino acid transport had its beginning and acquired a distinct momentum (even if somewhat interrupted from 1913 until about 1945) as amino acid metabolism with the central and pioneer work of Van Slyke and Meyer in 1913. The reviews in this volume will show that it steadily becomes a larger aspect of amino acid metabolism, broadly perceived. These chapters will show for how many organelles, cells, tissues, organs and organ systems, the transmembrane compartmentations and flows of amino acids play very large parts in their fundamental biological relations. The authors here are tending collectively to evaluate an understanding of amino acid flows across biomernbranes, and the regulation of these flows, as necessary to an ultimate understanding of the full range of development and metabolism. Such an understanding goes far beyond the purely substrate-destabilizing contributions by enzymes, which have often been arbitrarily limited to that conceptual entity, "the cell", and which for so long a splendid time had most of biochemical research attention.
