Download or read book The Biology of Ascidians written by H. Sawada and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ascidians are the invertebrate group that gave rise to vertebrates, thus the biology of ascidians provides an essential key to understanding both invertebrates and vertebrates. This book is the first to cover all areas of ascidian biology, including development, evolution, biologically active substances, heavy metal accumulation, asexual reproduction, host-defense mechanisms, allorecognition mechanisms, comparative immunology, neuroscience, taxonomy, ecology, genome science, and food science. The 69 articles that make up the collection were contributed by leading ascidiologists from all over the world who participated in the First International Symposium on the Biology of Ascidians, held in June 2000 in Sapporo, Japan. For scientists and students alike, the book is an invaluable source of information from the latest, most comprehensive studies of ascidian biology.

Download or read book Vanadium in Biological Systems written by N.D. Chasteen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, vanadium has increasingly attracted the interest of biologists and chemists. The discovery by Henze in 1911 that certain marine ascidians accumulate the metal in their blood cells in unusually large quantities has done much to stimulate research on the role of vanadium in biology. In the intervening years, a large number of studies have been carried out to investigate the toxicity of vanadium in higher animals and to determine whether it is an essential trace element. That vanadium is a required element for a few selected organisms is now well established. Whether vanadium is essential for humans remains unclear although evidence increasingly suggests that it probably is. The discovery by Cantley in 1977 that vanadate is a potent inhibitor of ATPases lead to numerous studies of the inhibitory and stimulatory effects of vanadium on phosphate metabolizing enzymes. As a consequence vanadates are now routinely used as probes to investigate the mechanisms of such enzymes. Our understanding of vanadium in these systems has been further enhanced by the work of Tracy and Gresser which has shown striking parallels between the chemistry of vanadates and phosphates and their biological compounds. The observation by Shechter and Karlish, and Dubyak and Kleinzeller in 1980 that vanadate is an insulin mimetic agent has opened a new area of research dealing with the hormonal effects of vanadium. The first vanadium containing enzyme, a bromoperoxidase from the marine alga Ascophyllum nodosum, was isolated in 1984 by Viltner.

Available in PDF, EPUB and Kindle. Book excerpt: Nature learned long ago how useful proteins are as a diverse set of building blocks to make materials with very diverse properties. Spider webs, egg whites, hair follicles, and skeletal muscles are all largely protein. This book provides a glimpse into both nature's strategies for the design and produc tion of protein-based materials, and how scientists have been able to go beyond the constraints of natural materials to produce synthetic analogs with potentially wider ranges of properties. The work presented is very much the beginning of the story. Only recently has there been much progress in obtaining a molecular understanding of some of nature's com plex materials, and the mimicry or replacement of these by synthetic or genetically engineered variants is a field still in its infancy. Yet this book will serve as a useful introduction for those wishing to get started in what is sure to be an active and productive field throughout the 21st century. The authors represent a wide range of interests and expertise, and the topics chosen are comprehensive. Charles R. Cantor Center for Advanced Biotechnology Boston University Series Preface The properties of materials depend on the nature of the macromolecules, small molecules and inorganic components and the interfaces and interac tions between them. Polymer chemistry and physics, and inorganic phase structure and density are major factors that influence the performance of materials.

Available in PDF, EPUB and Kindle. Book excerpt: A state-of-the-art work surveying the toxicology of important aquatic pollutants, this book provides a critical overview of the current research. It assesses the response at community, species, tissue, cellular, and subcellular levels to particular toxicants and covers the mechanisms of uptake, metabolism, and excretion of many toxic pollutants. Special attention is given to changes induced by toxicants in the biochemical and physiological systems of organisms. The book also covers recent developments in the methodology used in detecting pterturbations in life processes of aquatic biota induced by environmental toxins.
