The Journal Of Experimental Biology 196 Transporters

This collection of articles, edited by D. W. Halton, is the specially commissioned supplement to the journal Parasitology, volume 113.

The gold standard for industrial research now completely revised in line with current trends in the field, with all contributions extensively updated or rewritten. In 21 chapters readers can benefit from the key working knowledge of today's leading pharmaceutical companies, including Pfizer, AstraZeneca, and Roche. Drug developers from industry and academia present all the factors governing drug bioavailability, complete with practical examples and real-life data. Part I focuses on in vitro and in vivo measurements of physicochemical properties, such as membrane permeability and ionization. Part II discusses solubility and gastrointestinal absorption, while the third part is devoted to metabolism and excretory mechanisms. The much revised and expanded part IV surveys current in silico approaches to predict drug properties needed to estimate the bioavailability of any new drug candidate. The final part shows how poor bioavailability may be improved by various approaches during the development process. No other publication offers the same level of treatment on this crucial topic in modern drug development.

Biological cell membranes regulate the transfer of matter and information between the intracellular and extracellular compartments as basic survival and maintenance functions for an organism. This volume contains a series of reviews that are c- cerned with how epithelial plasma membranes regulate the transport of solutes between the intracellular and extracellular compartments of a cell. This book is also an attempt to analyze the molecular basis for the movement of various solutes across an epithelial cell membrane. This volume is devoted to a diversity of epithelial transport mechanisms in rep- sentative cell membranes of a variety of living things. The ?rst section of the book (Chapters 1–6) focuses on mechanisms of solute transport in epithelia of inver- brates. The last section which comprises ten chapters (Chapters 7–16) deals with solute transporters in epithelial cell membranes of vertebrates. It is hoped that with this particular ordering the reader can glean a telescopic view of the evolutionary history of the various epithelial solute transporters.

This book presents specially commissioned reviews of key topics in farm animal metabolism and nutrition, such as repartitioning agents, near infrared reflectance spectroscopy and digestibility and metabolisable energy assays, where major advances have recently been made or which continue to represent issues of significance for students and researchers. Authors include leading researchers from Europe, North America and Australia.

Factors Affecting Neurodevelopment: Genetics, Neurology, Behavior, and Diet is a comprehensive reference on the genetic and behavioral features associated with proper and abnormal development. The book discusses the mechanisms underlying neurological development and provides readers with a detailed introduction to the neural connections and complexities in biological circuitries, as well as the physiological, behavioral, molecular, and cellular features of neurodevelopment. In addition, the book examines in vitro and in vivo modeling of development with stem cells and model systems. Provides the most comprehensive coverage of a broad range of topics relating to the neuroscience of development Features sections on the genetics of developmental conditions and accompanying behavior Contains an abstract, key facts, mini dictionary of terms, and summary points to aid in understanding in each chapter Focuses on neurodevelopmental disorders and environmental factors that influence neural development Includes more than 500 illustrations and tables

Cation Transporters in Plants presents expert information on the major cation transporters, along with developments of various new strategies to cope with the adverse effects of abiotic and biotic stresses. The book will serve as a very important repository for the scientist, researcher, academician and industrialist to enhance their knowledge about cation transport in plants. Further, applications listed in the book will facilitate future developments in crop designing strategies. This comprehensive resource provides an alternative strategy for abiotic and biotic stress management in agricultural and horticultural crops. In addition, it will further improve basic knowledge om the origin and mechanism of cation homeostasis and their role in developmental transition and stress regulation. Contains in-depth knowledge about various cation transporters in plants Provides information about important macro and micronutrient cation transporters and their applications in the agricultural and biotechnology sectors Facilitates agricultural scientists and industries in future crop designing strategies Provides an alternative strategy for abiotic and biotic stress management in agricultural and horticultural crops

Covering advanced nutrition with a comprehensive, easy-to-understand approach, Biochemical, Physiological, and Molecular Aspects of Human Nutrition, 3rd Edition focuses on the biology of human nutrition at the molecular, cellular, tissue, and whole-body levels. It addresses nutrients by classification, and describes macronutrient function from digestion to metabolism. This edition includes the new MyPlate dietary guide and recommendations from the Dietary Guidelines for Americans 2010, plus coverage of the historical evolution of nutrition and information on a wide range of vitamins, minerals, and other food components. In Biochemical, Physiological, and Molecular Aspects of Human Nutrition, lead authors Martha H. Stipanuk and Marie A. Caudill are joined by a team of nutrition experts in providing clear, concise, coverage of advanced nutrition. 55 expert contributors provide the latest information on all areas of the nutrition sciences. Nutrition Insight boxes discuss hot topics and take a closer look at basic science and everyday nutrition. Clinical Correlation boxes show the connection between nutrition-related problems and their effects on normal metabolism. Food Sources boxes summarize and simplify data from the USDA National Nutrient Database on the amount and types of foods needed to reach the recommended daily allowances for vitamins and minerals. DRIs Across the Life Cycle boxes highlight the latest data from the Institute of Medicine on dietary reference intakes for vitamins and minerals, including coverage of infants, children, adult males and females, and pregnant and lactating women. Life Cycle Considerations boxes highlight nutritional processes or concepts applicable to individuals of various ages and in various stages of the life span. Thinking Critically sections within boxes and at the end of chapters help in applying scientific knowledge to "real-life" situations. Lists of common abbreviations provide an overview of each chapter's content at a glance. Comprehensive cross-referencing by chapters and illustrations is used throughout. Current references and recommended readings connect you to nutrition-related literature and provide additional tools for research. Coverage of the USDA's MyPlate dietary guide reflects today's new approach to diet and nutrition. Recommendations outlined in the Dietary Guidelines for Americans 2010 are incorporated throughout the book. Updated format features more subheadings, tables, and bullets, making it easier to learn and recall key points. Updates of key chapters and boxes reflect significant changes within the fields of nutrition, biology, molecular biology, and chemistry. NEW illustrations simplify complex biochemical, physiological, and molecular processes and concepts.
