Urea Transporters


Book Description

The mechanisms and physiological functions of urea transporters across biological membranes are subjects of long-standing interests. Although urea represents roughly 40% of all urinary solutes in normal human urine, the handling of urea in the tissues has been largely neglected in the past and few clinical or experimental studies now report data on urea. Most recent physiological text books include chapters on water and electrolyte physiology but no chapter on urea. Our aim in writing this book is to stimulate further research in new directions by providing novel and provocative insights into the further mechanisms and physiological significance of urea metabolism and transport in mammals. This book offers a state-of-the-art report on recent discoveries concerning urea transport and where the field is going. It mainly focuses on advances made over the past 20 years on the biophysics, genetics, protein structure, molecular biology, physiology, pathophysiology and pharmacology of urea transport in mammalian cell membranes. It will help graduate students and researchers to get an overall picture of mammalian urea transporters and may also yield benefits for pharmaceutical companies with regard to drug discovery based on the urea transporter. Baoxue Yang is a professor and vice chairman of the Department of Pharmacology, Peking University. He is also an adjunct professor of Jilin University and a visiting professor of Northeast Normal University. Prof. Yang has been researching urea transporters for nearly 20 years and has published more than 70 original research articles in this field.




The Urea Cycle


Book Description













Aquaporins


Book Description

The aquaporin field has matured at an exceptionally fast pace and we are at the verge to develop serious strategies to therapeutically modulate aquaporin function directly or via regulatory networks. Key prerequisites are available today: i. a considerable (and growing) number of aquaporin crystal structures for the rational design of inhibitory molecules, ii. elaborate molecular dynamics simulation techniques for theoretical analyses of selectivity mechanisms and docking experiments, iii. comprehensive data on aquaporin immunohistochemistry, iv. aquaporin knockout animals for physiological studies, and v. assay systems for compound library screenings. The structure of this volume on aquaporins follows the points laid out above and thus covers the developments from basic research to potential pharmacological use. Situated between pharmacology textbooks and recent scientific papers this book provides a timely overview for readers from the fundamental as well as the applied disciplines.




Textbook of Nephro-Endocrinology


Book Description

The Textbook of Nephro-Endocrinology is the definitive translational reference in the field of nephro-endocrinology, investigating both the endocrine functions of the kidneys and how the kidney acts as a target for hormones from other organ systems. It offers researchers and clinicians expert, gold-standard analyses of nephro-endocrine research and translation into the treatment of diseases such as anemia, chronic kidney disease (CKD), rickets, osteoporosis, and, hypoparathyroidism. Investigates both the endocrine functions of the kidneys and how the kidney acts as a target for hormones from other organ systems Presents a uniquely comprehensive and cross-disciplinary look at all aspects of nephro-endocrine disorders in one reference work Clear translational presentations by the top endocrinologists and nephrologists in each specific hormone or functional/systems field







Molecular and Genetic Basis of Renal Disease


Book Description

This companion to Brenner and Rector's The Kidney offers a state-of-the-art summary of the most recent advances in renal genetics. Molecular and Genetic Basis for Renal Disease provides the nephrologist with a comprehensive look at modern investigative tools in nephrology research today, and reviews the molecular pathophysiology of the nephron as well as the most common genetic and acquired renal diseases.

Detailed review of the molecular anatomy and pathophysiology of the nephron that provides relevant basic science to consider when diagnosing and managing patients with these disorders.




Regulation of Tissue Oxygenation, Second Edition


Book Description

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
