  • Enzymes in Blood Plasma

    • 1 Edición
    • Benno Hess
    • Inglés
    Enzymes in Blood Plasma gives a comprehensive account of the current state of research and practical application of biochemistry and biology, as well as the pathology and clinical aspects of plasma enzymes. Enzymes in blood plasma, for reasons of principle and methods, are not limited to plasma-specific enzymes, which are only briefly mentioned. Emphasis will rather be placed on plasma-nonspecific enzymes, i.e., enzymes of identical properties in plasma and serum. Their action is, for technical reasons, generally determined in serum. The enzymes in plasma will be stressed in this presentation, but the situation in other extracellular spaces and even extracorporeal areas such as urine, excreta, and feces will be included. There exists no basic difference of enzyme function in these biological areas. Many of the findings reported in this volume were obtained with the old units and methods, rather than the International Unit. For this reason, the section dealing with methods includes a table for conversion, which can be used for comparison of data, insofar as these data were obtained under optimalconditions of measurement.

  • Methods in Polyphenol Chemistry

    Proceedings of the Plant Phenolics Group Symposium, Oxford, April 1963
    • 1 Edición
    • J. B. Pridham
    • Inglés
    Methods in Polyphenol Chemistry documents the proceedings of the Plant Phenolics Group Symposium held at the University of Oxford, on 2-4 April 1963. The symposium focused on the methods and techniques which made advances in the chemistry and biochemistry of phenolic compounds possible. The development of paper chromatographic and ultraviolet spectroscopic techniques was particularly important and largely responsible for the rapid growth in knowledge of polyphenols which has occurred during the last 10-15 years. In addition to these two methods other spectroscopic techniques were dealt with at the symposium. Particular mention should perhaps be made of nuclear magnetic resonance spectroscopy which is becoming increasingly important in polyphenol chemistry. Modern chromatographic methods such as thin layer and gas-liquid techniques will probably be used extensively in the future. These will enable the analyses of polyphenol mixtures to be carried out more rapidly and with greater resolution. Polyamide chromatography also has high powers of resolution, although this technique has not been widely used owing to difficulties in obtaining supplies of polyamide powder. This situation has now improved, however.

The next chapters deal with the historical developments and pharmacology of drugs in cerebral palsy, as well as the two aspects of drug evaluation, namely, the immediate or direct effects of the drug on patients and the double-blind test. The discussion the shifts to the pharmacological capacity of muscle relaxants and anti-convulsant drugs. The last chapter considers the possible toxic drug reactions, which are the result of individual idiosyncrasy and may occur regardless of drug dosage. This book will be of value to pharmacologists, neurologists, clinicians, and researchers who are interested in drug evaluation in cerebral palsy.

    • Inglés
    Water Relations in Membrane Transport in Plants and Animals contains the presentations in a symposium dealing with Water Relations in Membranes in Plants and Animals, during the 27th Annual Fall Meeting of the American Physiological Society held at The University of Pennsylvania, 17-19 August 1976. The purpose of the symposium was to explore the common modes of water regulation in plants and animals. In these proceedings, the mechanisms employed to restrict water flow across plant and metazoan animal cells are described. Putative differences in mechanisms of water regulation retained by plant versus animal cells become inconsequential in the light of the numerous similarities: dependence upon bioelectric potentials maintained across cell membranes, energy dependence of uphill water movement, and solute coupling during water transport. The presentations can be organized into four. The first takes up specific mechanisms of water transport in plants. The second and third parts deal with specific mechanisms in invertebrates and vertebrates, respectively. The fourth part covers generalized mechanisms common to plants and animals.

    Soil Fungi and Soil Fertility, Second Edition is an introduction to soil microbiology, incorporating significant advances in knowledge and understanding of the way micro-organisms live and function under laboratory and natural conditions. This book is comprised of nine chapters, discusses soil microbiology, and shows how the living ecosystem of the soil helps maintain soil fertility and crop production. This text begins with a description of the soil as a habitat, encompassing both its physical and chemical characteristics. The root systems, soil fauna, and soil micro-organisms or the Protist Kingdom all form the living inhabitants of the soil. The components of soil fungi from the organization and growth of its branching system called mycelium to the asexual reproduction and final dispersion are explained. This book also discusses genetic mechanisms in fungi and nuclear division that is a compensatory reduction in the number of chromosomes back to the haploid number that must occur. This text also presents a comparison of further studies of the fungal communities through microscopic and cultural methods, as well as other methods that would yield better soil fungi and soil fertility. Also considered are factors that affect the competitive saprophytic colonization of substrates by soil fungi, and then how these fungi exploit their colonized substrates for survival. This monograph then examines the root-infecting fungi through their ability to feed on living plant tissues and how a balanced host-parasite relationship actually benefits the fungi community.This book is suitable for soil mycologists, soil researchers, agriculturists, and university undergraduates interested in soil microbiology.

    • Inglés
    Opiate Receptors and the Neurochemical Correlates of Pain, Volume V, documents the proceedings of the 3rd Congress of the Hungarian Pharmacological Society held in Budapest, 1979. The congress offered a good opportunity to stimulate discussions and exchange of ideas between scientists from various countries who approach the problem of narcotics and pain mechanisms in different ways. The 27 contributions in this volume have enriched knowledge in this rapidly expanding field of pharmacology. This volume begins with a discussion of opiate receptors. The results suggest the interaction of various morphine-like drugs with different opiate receptor populations. The existence in nerve tissue of specific opiate receptors binding morphine and other opioids has led to the assumption of endogenous ligand for opiate receptors. One section of the present volume is devoted to enkephalins and endorphins, their structure-activity relationships, interactions with transmitter and other systems, their behavioral effects, and to factors controlling their release. Some other aspects of nociception; the pathways involved in the mode of action of different types of analgesics, e.g. narcotics and non-narcotics; and their relations to inflammation and active substances, such as prostaglandins and substance P, are discussed from various aspects.
