    • 1 Edición
    • W. Hanke + 1 más
    • Inglés
    Biological Techniques is a series of volumes aimed at introducing to a wide audience the latest advances in methodology. The pitfalls and problems of new techniques are given due consideration, as are those small but vital details not always explicit in the methods sections of journal papers.In recent years, most biological laboratories have been invaded by computers and a wealth of new DNA technology and this will be reflected in many of the titles appearing in the series.The books will be of value to advanced researchers and graduate students seeking to learn and apply new techniques, and will be useful to teachers of advanced undergraduate courses involving practical or project work.Methods of constructing artificial membranes (planar lipid bilayers) from the main components of cell membranes (lipids) date from the early 1960s.Planar bilayers offer direct, quantitative experimental approaches to the study of membranes of precisely determined composition which can be manipulated by the experimenter. Pore-forming molecules, transporter molecules, ATP-dependent enzymes and other entities can be incorporated into the bilayers to simulate biological functions.Reconstitu... of such functions in this way remains a key final step in attributing a functional role to purified cell membrane proteins.This book aims to demystify these techniques and begins with a broad overview of the development of the subject before dealing with the protocols involved.Key references are provided at the end of the book together with a list of suppliers.

  • Neurotransmitter Release the Neuromuscular Junction

    • 1 Edición
    • Francesco Clementi
    • Inglés
    Neurotransmitter Release: The Neuromuscular Junction is a collection of papers presented at a small meeting organized in the University of Milan to honor Bruno Ceccarelli. Ceccarelli was particularly interested in the structure and functioning of the neuromuscular junction and spent the rest of his career characterizing the process of neurotransmitter release, and eventually providing the strongest available support for the widely accepted ""vesicle hypothesis"" of neurotransmitter release. The meeting was intended to gather as many scientists who had been directly in touch with Bruno as possible and to discuss together problems of Bruno's interest. Organized into 20 chapters, the book first discusses the organelles of distinct secretory pathways involved in distinct types of neuronal signaling, such as synapsins, synaptophysin , and synaptobrevin. It then examines the role of coated vesicles, acetylcholine compartments, and potassium and calcium channels on neurotransmission processes. Other topics considered are the regeneration of nerve-evoked neurotransmission; the single-channel recordings of KNa in avian sensory neurons; the modulation of voltage-dependent calcium currents in identified snail neurons; and the agonistic/antagonist... action of calcium channel in mammalian peripheral neurons. Cross-talks between receptors coupled to calcium currents and between different intracellular signaling are provided in the last chapters of the book. These chapters also look into the relevance of lipoxygenase metabolites of arachidonic acid to cell-to-cell communication in the central nervous system. This book is an invaluable source for scientists, researchers, and students who are interested in basic neurology.

  • An Introduction to Animal Law

    • 1 Edición
    • Cooper
    • Inglés
    Legislation relating to animals has ancient origins and in many civilizations certain species have held particular significance, be it religious, cultural, nutritional, or sporting. As a general rule, the law was primarily concerned with animals as property, rather than in need of protection, until the 19th century. Since the 1970s animal law has proved to be a growth area in the production and enforcement of both national and international legislation. This has been particularly so in the areas of conservation and welfare and there has been extensive legal and philosophical consideration of the status of animals.This book is not intended to be a standard text, but rather a handbook in the true sense, a guide for the lay person--namely, to help the non-lawyer to understand the basic concepts of animal law and to provide the lawyer (who is the lay person in the world of animal science) with an introduction to relevant concepts and literature which are not normally found in the conventional legal texts.

  • Transport And Diffusion Across Cell Membranes

    • 1 Edición
    • Wilfred Stein
    • Inglés
    Transport and Diffusion across Cell Membranes is a comprehensive treatment of the transport and diffusion of molecules and ions across cell membranes. This book shows that the same kinetic equations (with appropriate modification) can describe all the specialized membrane transport systems: the pores, the carriers, and the two classes of pumps. The kinetic formalism is developed step by step and the features that make a system effective in carrying out its biological role are highlighted. This book is organized into six chapters and begins with an introduction to the structure and dynamics of cell membranes, followed by a discussion on how the membrane acts as a barrier to the transmembrane diffusion of molecules and ions. The following chapters focus on the role of the membrane's protein components in facilitating transmembrane diffusion of specific molecules and ions, measurements of diffusion through pores and the kinetics of diffusion, and the structure of such pores and their biological regulation. This book methodically introduces the reader to the carriers of cell membranes, the kinetics of facilitated diffusion, and cotransport systems. The primary active transport systems are considered, emphasizing the pumping of an ion (sodium, potassium, calcium, or proton) against its electrochemical gradient during the coupled progress of a chemical reaction while a conformational change of the pump enzyme takes place. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in biochemistry, physiology, pharmacology, and biophysics.

    • Inglés
    Plant Nonprotein Amino and Imino Acids: Biological, Biochemical, and Toxicological Properties provides a comprehensive discussion of plant nonprotein amino acids. Much of this monograph is written with the neophyte in mind, thus necessitating the presentation of certain basic concepts that are well-known to the advanced worker. Rather than providing an exhaustive coverage of the subject matter, the book attempts to represent effectively the state of the art; to provide a helpful means of identifying and locating the pertinent literature; and to present the basic information necessary to encourage other workers to enter into the study of the nonprotein amino acids. The book begins with a review of nomenclature and physicochemical properties. This is followed by a discussion of analytical methods such as partition paper chromatography, thin-layer chromatography, ninhydrin color reaction, ion-exchange chromatography, and gas chromatography. Subsequent chapters deal with the toxicity of some nonprotein amino acids and their ability to exert debilitating effects in a host of organisms; and the intermediary metabolism of nonprotein amino acids.

    • Inglés
    The Biology of Crustacea, Volume 6: Pathobiology summarizes the state of knowledge, major advances, and important problems in crustacean diseases. Organized into five chapters, this book begins with the discussion on the disease-causing viruses, Rickettsiae, bacteria, and fungi afflicting crustaceans. It then talks about diseases caused by protozoans, indicating the large gaps in knowledge of life histories, mechanisms of transmission, and pathogenesis. This book also emphasizes the many different ways in which a host crustacean may respond to a disease-causing organism and how these responses are linked to the mode of invasion and nature of the disease-causing organism, itself. The life histories of metazoans that live in various relationships in or on crustacean hosts, and the life histories and impacts of parasitic crustaceans on hosts are also explored. This book will serve as a starting point for those needing a summary of topics concerning crustacean diseases and as a stimulus for further work.

  • Agricultural Ecology and Environment

    The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.
