    Advances in Endogenous and Exogenous Opioids contains the proceedings of the International Narcotic Research Conference (Satellite Symposium of the 8th International Congress of Pharmacology) held in Kyoto, Japan on July 26-30, 1981. The conference provided a forum for discussing advances that have been made in the understanding of endogenous and exogenous opioids and tackled a wide array of topics ranging from novel opiate binding sites selective for benzomorphan drugs to the purification of opioid receptors and sequellae of receptor binding. Comprised of 156 chapters, this book begins with an analysis of the interaction of opioid peptides and alkaloid opiates with mu-, delta-, and kappa-binding sites. The reader is then systematically introduced to biochemical evidence for kappa and sigma opiate receptors; the action of morphine and oxymorphone as partial agonists on the field-stimulated rat vas deferens; mechanisms of supersensitivity in the enkephalinergic system; and properties of the solubilized opiate receptor from human placenta. Subsequent chapters explore the biosynthesis of opioid peptides as well as their localization, release, and degradation; physiological and pharmacological actions of opioids; and the use of analgesia in acupuncture. Results of behavioral and clinical studies of endogenous and exogenous opioids are also presented, and the structure-activity relationships of opioids are examined. This monograph will be of interest to students, practitioners, and researchers in the fields of psychiatry and pharmacology.

    • Inglés
    Plant Proteins is a compendium of papers discussing, in general, plant proteins as materials for human foods, and in particular, the properties, biosynthesis, deposition of reserves in seeds, undesirable factors, production, and nutritional aspects of plant proteins in the food industry. Some papers review the properties and biosynthesis of plant proteins, the synthesis of chloroplast proteins, and legume seed proteins. Other papers discuss the development of protein reserves in seeds, as well as the toxicity and antagonistic actions in relation to amino acid and protein synthesis. One paper examines the world supply and demand for sources of protein from three plant sources, namely cereals, oilseeds, and legumes. Another paper discusses the capabilities of certain species of micro-organisms to synthesize from a few simple raw materials all the main components needed in the diet of a human or a farm animal. One paper notes that the acceptance of plant protein foods in society depends on their presentation, flavor, texture, appearance, identity, and product name. This compendium will benefit agronomists, agriculturists, biochemists, microbiologists, nutritionists, botanists, chemists, economists, food scientists, physicists and plant breeders.

    • Inglés
    Cardiovascular Review 1982 is an attempt to survey and organize much of the English speaking literature as concisely and expeditiously as possible for those who wish to remain current but have insufficient time for this purpose. The format of the 1982 edition has been changed in the service of space and editorial costs. An outline mode of presentation has been continued while abandoning wasteful indentations of text. Almost all references have been retained for their bibliographic value unless they were felt to be no longer germane to the matrix of medical thinking. With the exception of a few statements and paragraphs in a number of sections, the book has been virtually entirely rewritten. With the addition of 2113 references in the current review, the total number of papers currently identified is well in excess of 5000. The table of contents has been constructed to reflect the order in which the preponderance of cardiologic literature appears. Thus, ischemic heart disease, valvular heart disease, arrhythmias, and conduction defects have been assigned a high priority reflected by their location in the first few sections of this book. Thereafter, topics ranging from acromegaly to tumors of the heart have been addressed in alphabetical order.

    These proceedings contain most of the oral presentations and posters of the international symposium on Stability and Stabilization of Enzymes held in Maastricht in November 1992. They provide a comprehensive overview of the state-of-the-art in this field.The possible applications of enzymes are enormous. Years of development have seen many enzymes brought onto the market, but they are still expensive to use. Therefore, their efficient application is a prerequisite for common usage. One of the main factors for this efficiency is the stability of the enzymes. The topics thus ranged from the extensive fundamental thermodynamic knowledge gathered in academic research to the practical applied knowledge built up in industry during the time that enzymes have been produced commercially.The subject Stability and Stabilization of Enzymes was discussed from various points of view, as was reflected in the themes of the symposium sessions. In the session on Fundamentals of Enzyme Stabilisation the thermodynamic background of the phenomenon was highlighted. In yet another session, the recently developed analytical tools to measure enzyme stability and stabilisation were discussed. Further sessions comprised the physical, chemical and biological ways to obtain enzyme stabilisation and finally, the industrial practice of enzyme stabilisation was treated by representatives of the world's most important enzyme producers. The book will be of interest to researchers in universities and industry in the fields of biochemistry, enzymology and biotechnology.

    • Inglés
    Some pioneers in soil research such as Müller and Kubiëna were as much biologists as they were soil scientists and the legendary biologist Charles Darwin was foresighted in recognizing the earthworms as instrumental in reworking the soil, thereby forming what he called "vegetable mould". Still, soil science has largely been the realm of physicists and chemists over the past decades. Whatever the reason, this picture is rapidly changing. Until recently, research on the transport and transformation of elements in soil was often concerned with either soil biota/plant relationships or with soil structure/plant relationships, if the biota were considered at all, but very few studies explicitly took the interrelationships between soil structure and soil biota into account. The conference on Soil Structure/Soil Biota Interrelationships, held at Wageningen, The Netherlands, 24-28 November 1991, was meant to bridge that gap, focussing on methods of research, organized in three levels: features, processes and effects. The proceedings of the conference are testimony of the need to intertwine the biological, morphological, physical and chemical disciplines in soil research to understand better and forecast soil properties and processes as related to land use for agricultural and other purposes.This book should be of particular interest to soil scientists and ecologists who feel the need for a cross-disciplinary approach in soils research. It should also be a rich source of teaching material for courses in soil science and soil ecology at graduate level and above, with ample reference to studies on land use as related to agriculture and the environment.

    • Inglés
    Physiology and Toxicology of Male Reproduction is a collection of papers that deals with general reproductive biology and specific aspects of reproductive toxicology, pertaining to the male sex. Some papers discuss testicular organization, reproductive toxicity testing systems, and germ-cell genetic toxicology. The use of in vitro systems by investigators to dissect the male reproductive toxicants can lead to a more scientific approach toward hazard assessment and the development of safer drugs and chemicals. Other papers explain the fundamental reproductive biology of the testis, the neuroendocrine system, the epididymis and accessory sex organs, and spermatozoal evaluation. Toxicological aspects cover the toxicological evaluation of the complete reproductive system, testicular morphology, sperm assessment, and germ-cell mutagenesis. One paper describes alternative methods in toxicology—by using new in vitro systems that should reduce or eliminate the need for tests conducted on animals. In vitro methodology embraces other systems such as from subcellular fractions to isolated intact organs. In relation to target-organ toxicity, the researcher can focus using primary cell cultures. This collection will prove helpful to toxicologists, graduate students and researchers in biology, particularly in male reproductive toxicology and fertility testing.

  • Agrammatism

    • Mary-Louise Kean
    • Inglés
    Agrammatism provides an overview of the state of knowledge on agrammatism, typically defined as a disorder of sentence production involving the selective omission of function words and some grammatical endings on words. The book opens with discussions of the diversity of the disorder. This is followed by separate chapters that address primarily questions of syntactic structure in agrammatism, from both linguistic and psycholinguistic perspectives. Within these two gross sections there is no consensus among the conclusions reached by the various authors. However, the position is taken that agrammatism is a disorder distinct from other aphasie disorders of sentence structure. This position is reconsidered in the final two chapters. Because of the intrinsically interdisciplinary character of research on agrammatism, it is hoped that the work presented in this volume will be of interest to linguists and psycholinguists working in areas outside the domain of aphasia, as well as to neurolinguists and neuropsychologists who are already involved in the study of language deficits.

    Engström-Finean Biological Ultrastructure, Second Edition, looks upon biological phenomena essentially as patterns of physical and chemical events organized in space and time. It attempts to describe the spatial aspects of this organization, emphasizing in particular the fundamental roles of individual types of molecules. It also introduces a minimum background of fundamental structural information and of techniques so as to aid in the appreciation of the significance of experimental data. The plan of the book in the present edition remains unchanged but the tremendous advances of recent years have necessitated changes in emphasis in the treatment of methods and fundamentals of structure and a complete reappraisal of biological ultrastructure. Key topics discussed include methods in ultrastructural research, the principles of molecular structure; the role of proteins, nucleic acids, lipids, carbohydrates, mineral salts; and the role of ultrastructure in biology and medicine.

    The Toxicology of Radioactive Substances, Volume 3: Iron-59 deals with the experimental results of tests conducted at the Radiotoxicology Laboratory of the Institute of Occupational Hygiene and Disease, Academy of Medical Sciences, U.S.S.R. The book focuses on studies made on iron-59, which is widely used in science and technology, such as in the metal industry and in the research of hemoglobin metabolism in the bone marrow and red cells. Other studies show, however, that there is a long-term detrimental effect of intake of iron-59. The text then gives a brief outline of the physical, chemical, and biological properties of iron. Research also shows that the body's reaction to radioactive substances depends on how these are transmitted to the body and on their physicochemical properties. The effect of prolonged administration of radioactive iron on the electrical activity of the cerebral cortex of animals is analyzed, of which, possibly, the nervous system is most affected. The book notes also the changes in the red blood cells during chronic administration of iron-59 in small doses, wherein the hemoglobin levels increased temporarily. Studies of prolonged exposure to radioactive isotopes during pregnancy of the test animals show that there are significant changes in erythropoiesis, associated with iron deficiency. In another study, the prolonged internal administration of radioactive substances showed phasic changes in the height of electrocardiographic waves of the test animals. The text is suitable for physicists, nuclear scientists, doctors of toxicology, and researchers in nuclear medicine.

    Food Legislative System of the UK discusses the principles underlying the country's food laws, the historical context of today's food legislation, and the process for amendments in legislation. The book also reviews the influences on the system such as those arising from interest groups, the changing diet, and health environment. In addressing the Food Legislative System of the United Kingdom, the book tackles various examples of food legislation and numerous food- related advisory bodies. Industry, consumer, or enforcement pressures can initiate changes and modifications of laws. Once ministers are convinced that a prima-facie case exists for amending food legislation, they will seek advice from various authorities; make a draft, and present it for full parliamentary procedure. For example, the "Food and Environment Bill" has passed through Parliament by ministers representing the Ministry of Agriculture, Fisheries and Food, while the "Food Bill" has gone through another route with the chief legal officers and company. The book emphasizes the mechanisms through which change is achieved, as well as the points when opportunities exist for interest groups to make their views known to the decision makers. The book can be helpful for food lobbyists, consumer food groups, nutritionists, political scientists, and heads of food and welfare organizations.
