  • Soil Structure/Soil Biota Interrelationships

    International Workshop on Methods of Research on Soil Structure/Soil Biota Interrelationships, Held at the International Agricultural Centre, Wageningen, The Netherlands, 24-28 November 1991
    • 1 Edición
    • L. Brussaard + 1 más
    • 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.

  • Animal Biotechnology

    Comprehensive Biotechnology, First Supplement
    • 1 Edición
    • L.A. Babiuk + 2 más
    • Inglés
    The advent of biotechnology has the potential to develop a variety of novel or better quality products for the treatment of a large number of diseases in livestock. In addition, as we understand more about the reproductive physiology of animals, the potential exists to dramatically increase the productivity of animals through better therapeutics and diagnostics for the control of many infectious diseases. Productivity can also be increased through animal breeding strategies including gene transfer, micromanipulation of embryos and gamete sex selection. As well as being a valuable reference to current knowledge in these areas, this first supplement to Comprehensive Biotechnology also looks at societal concerns over the use of antibiotics and chemical residues in meat and milk products, which are forcing biotechnologists to investigate more natural means of controlling infection by stimulating the animal's own immune system to combat infection. The identification of a variety of cytokines which are involved in regulating immune responses provides opportunities to use the animal's natural defence mechanisms to combat many infections or increase the animal's resistance to such infections. These approaches should provide tools for eventual elimination of specific diseases from counties, regions or whole continents.

    Cisplatin: Current Status and New Developments is a collection of papers presented at a symposium sponsored by the University of Alabama in Birmingham Comprehensive Cancer Center and the Bristol Laboratories in Syracuse, ?ew York, and held on September 27-28, 1979, in Atlanta, Georgia. The symposium provided a forum for assessing developments with regards to cisplatin as an anticancer drug, with emphasis on its clinical application in a wide variety of adult and pediatric malignancies as well as the mechanism by which the drug appears to cause tumor cell death. Comprised of 39 chapters, this book begins with a preclinical overview of cisplatin, focusing on its mechanism of action, pharmacology, antitumor activity, analogs, and toxicity. The discussion then turns to the effects of cisplatin on DNA and the possible relationships to cytotoxicity and mutagenicity in mammalian cells; lethal activity of platinum compounds in combination with pyrimidine derivatives; and ultrastructural effects of cisplatin. Subsequent chapters focus on the rationale of combination chemotherapy; toxic side effects of platinum analogs; radiopharmacokinetic... of cisplatin; and the use of cisplatin for the treatment of malignancies such as ovarian cancer and advanced adenocarcinoma of the prostate. This monograph will be useful to oncologists and pharmacologists.

  • Assessing Ecological Risks of Biotechnology

    • Lev R. Ginzburg
    • Inglés
    Assessing Ecological Risks of Biotechnology presents a comprehensive analysis of ecological risk assessment for biotechnology as viewed predominantly by scientists doing research in this area, but also by regulators, philosophers, and research managers. The emphasis is on the ecological risks associated with the release of genetically engineered organisms into the environment. The book contains 17 chapters that are organized into four parts. Part I discusses the ecological experience gained from previous biological introductions. Part II explores the ecology and the genetics of microbial communities. Emphasis is given to the transport of microorganisms since one of the major ecological concerns about biotechnology is the danger of the spread of genetically engineered organisms to ecosystems other than the one to which they are released. Part III reviews mathematical models that can be used for ecological risk assessment at four different levels. Part IV concerns the regulation of biotechnology, current research trends, and social values.

    Pharmacology in Clinical Practice describes basic pharmacology, clinical pharmacology, including the pharmacology of important drug groups. The author reviews the general principles of clinical pharmacology including drug actions, absorption, disposition, and excretion. Most drugs are xenobiotics—compound... foreign and harmful to human living tissues. Drugs should be properly metabolized and converted to nontoxic substance before being excreted either through spontaneous changes not mediated by enzymes or through transformation by enzyme systems. The author also discusses pharmacokinetics, including drug plasma concentration, absorption, first-pass metabolism, distribution and elimination. The author addresses pharmacogenetics that deal with possible different responses to drug intake due to factors such as age, sex, liver or renal disease, smoking, diet. The book tackles other drugs, their uses, and characteristics such as antibacterial agents, obesity drug, cytotoxic drugs or those used in chemotherapy medicine. The author explains the diagnosis of drug ingestion, clinical signs of overdose, clinical course, and prophylactic measures for users to avoid drug overdose or self-poisoning.
