  • The Role of Selenium in Nutrition

    • 1st Edition
    • Gerald F. Jr. Combs
    • English
    The Role of Selenium in Nutrition reviews the most pertinent scientific literature dealing with the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. The book begins with a general discussion of Se, covering its various forms, chemistry and physical properties, and techniques for Se analysis. This is followed by separate chapters on the environmental aspects of Se, including its presence in mineral deposits, soils, water, air, and uptake by plants; Se contents of human foods and animal feedstuffs; biological utilization of dietary Se; and absorption, excretion, metabolism, and tissue concentrations of Se. Subsequent chapters deal with the biochemical functions of Se; Se-related diseases of animals and livestock; the role of Se in human health and in support of normal immune function and disease resistance; and the relationship of Se and cancer. The final chapter reviews the evidence concerning the toxicity of Se compounds and sets this in perspective with current knowledge of the roles of Se in nutrition and health, and of the normal exposures of animals and humans to Se compounds.
  • Flow Visualization

    • 1st Edition
    • Wolfgang Merzkirch
    • English
    Flow Visualization describes the most widely used methods for visualizing flows. Flow visualization evaluates certain properties of a flow field directly accessible to visual perception. Organized into five chapters, this book first presents the methods that create a visible flow pattern that could be investigated by visual inspection, such as simple dye and density-sensitive visualization methods. It then deals with the application of electron beams and streaming birefringence. Optical methods for compressible flows, hydraulic analogy, and high-speed photography are discussed in other chapters. With appropriate flow pictures, this book tries to distinguish the various methods and the range of their applicability by outlining the physical principles on which each method is based.

    • 1st Edition
    • Fazal Ahmad
    • English
    From Gene to Protein: Translation into Biotechnology is the 15th volume in the continuing series under the title ""Miami Winter Symposia"". The theme of the symposium is the translation of the basic research findings into the practical application of biotechnology. This book summarizes methodology and its applications that lie behind the practical innovations. The book starts with reviews of techniques of eukaryotic cell culture, hybridoma technology and uses, and the in vitro synthesis of DNA and its use in the generation of protein analogs. Considerable space is devoted to development of monoclonal antibodies that promises to be the dominating tool of medical technology, both for diagnosis and therapy. Cloning into eukaryotic cells and methods of increasing the levels of gene expression are included. These topics reflect areas of intensive research that have important commercial and clinical value. Core chapters describe biological activities of cloned gene products, including reports on trials with human subjects of interferon, human insulin, and growth hormone. A panel session on horizons in biotechnology is also provided, looking forward to the directions of future research and its applications. Biotechnologists, cell biologists, scientists, researchers, teachers, and students will greatly benefit from this book.

    • 1st Edition
    • Donald S. Farner + 2 more
    • English
    Written by international experts from many disciplines, this multi-volume treatise is a comprehensive survey of the established data and principles of avian biology. The volumes thoroughly review knowledge of the 8600 living species of birds-knowledge resulting from advances in instrumentation and technology and improved transportation facilities that permit more detailed, far-ranging field studies than ever before. The emphasis is on the significance of avian biological research to such areas of biology as ethology, ecology, population biology, evolutionary biology, and physiological ecology.
  • Challenging Problems in Organic Reaction Mechanisms

    • 1st Edition
    • Darshan Ranganathan
    • English
    Challenging Problems in Organic Reaction Mechanisms explores the problems encountered in the study of the various facets of organic chemistry, including syntheses, reactions, reagents, and reaction mechanisms. Each problem describes the starting material, the conditions of the reaction, and the product, followed by the reference to the original publication. This permits the reader to solve the problem independently and then compare the results with those presented in the literature. The example problems are arranged in such a manner that each page is balanced. The utility of this collection has been enhanced by inclusion of, first, a ""compound index"" which allows rapid identification of rearrangements associated with a specific substrate; second, a ""reaction-type index"" which unifies reactions associated with a particular transition state and brings into focus the usefulness of Woodward-Hoffman notations in understanding bond formation and cleavage; and, finally, a ""problem classification index"". This work is of great value to organic chemists and researchers and organic chemistry teachers and students.
  • Techniques in Protein Chemistry

The structure of synthetic test peptide-3 (STP-3), a peptide designed to test the analytical limits of current technology in the field of protein chemistry is also elaborated. This publication is suited for chemists and researchers conducting work on the analytical techniques available for the molecular characterization of proteins.
  • Optimizing The Soil Physical Environment Toward Greater Crop Yields

    • 1st Edition
    • Daniel Hillel
    • English
    Optimizing the Soil Physical Environment Toward Greater Crop Yields contains the proceedings of an invitational panel convened during the International Symposium on Soil-Water Physics and Technology held at The Hebrew University Faculty of Agriculture in Rehovot, Israel, August 29 to September 5, 1971. Organized into 13 chapters, this book begins with a discussion on the criteria for determining the aims and direction of research in soil physics and technology. Some chapters deal with the transformation and fluxes of energy and matter in the field, particularly water, soil temperature, soil structure, soil salinity, radiation climate, and nutrient supply and uptake. The book also explores the methods of measuring, managing, and modifying the crop production system to greater agricultural advantage. This book will reflect not only what is known, but also what is missing in the incomplete conception of this environment.
  • RNA and Protein Synthesis

    • 1st Edition
    • Kivie Moldave
    • English
    RNA and Protein Synthesis is a compendium of articles dealing with the assay, characterization, isolation, or purification of various organelles, enzymes, nucleic acids, translational factors, and other components or reactions involved in protein synthesis. One paper describes the preparatory scale methods for the reversed-phase chromatography systems for transfer ribonucleic acids. Another paper discusses the determination of adenosine- and aminoacyl adenosine-terminated sRNA chains by ion-exclusion chromatography. One paper notes that the problems involved in preparing acetylaminoacyl-tRNA are similar to those found in peptidyl-tRNA synthesis, in particular, to the lability of the ester bond between the amino acid and the tRNA. Another paper explains a new method that will attach fluorescent dyes to cytidine residues in tRNA; it also notes the possible use of N-hydroxysuccinimide esters of dansylglycine and N-methylanthranilic acid in the described method. One paper explains the use of membrane filtration in the determination of apparent association constants for ribosomal protein-RNS complex formation. This collection is valuable to bio-chemists, cellular biologists, micro-biologists, developmental biologists, and investigators working with enzymes.
  • Role of the Gut Flora in Toxicity and Cancer

    • 1st Edition
    • I Rowland
    • English
    Role of the Gut Flora in Toxicity and Cancer examines the relationship between the gut microflora and its host. The aim is to provide a comprehensive view of the contribution of the gut flora to foreign compound metabolism in man and laboratory animals. The object has been to relate this bacterial metabolism to toxic events occurring in mammals and to consider the interrelationships of bacterial and mammalian metabolic pathways. The early chapters are set the scene and provide a background to the sections on metabolism of specific groups of compounds which follow. Subsequent chapters encompass the bacterial metabolism of both xenobiotics and food components, and concentrate on those reactions which have actual or potential toxicological and/or clinical importance. The concluding chapters provide assessments of the role of the gut flora in the etiology of cancer, in particular from the point of view of the formation of carcinogens, mutagens, and promotors within the large bowel.
