    • Inglés
    Nitrogen in the Environment, Volume 2: Soil-Plant-Nitrogen Relationships is the second of a two-volume treatise based on manuscripts presented at the international conference on ""Nitrogen in the Environment,"" held at the University of California Conference Center, Lake Arrowhead, in February, 1977. All original manuscripts were revised in accordance with discussions at the conference. The chapters published in these volumes are those revised manuscripts, with provisions in each chapter to preserve the major suggestions for their improvement. These two volumes—Nitrogen Behavior in Field Soil and Soil-Plant-Nitrogen Relationships—should be of value in bringing into perspective current knowledge on selected aspects of nitrogen in the environment. The book contains 22 chapters and opens with a study on the factors influencing nitrate acquisition by plants; assimilation and fate of reduced nitrogen. Separate chapters follow on topics such as absorption and utilization of ammonium nitrogen by plants; potential nitrate levels in edible plant parts; control of biological nitrogen fixation; and methods for analysis of denitrification in soils.

  • Evolution of Living Organisms

    Evidence for a New Theory of Transformation
    • 1 Edición
    • Pierre-P. Grassé
    • Inglés
    Evolution of Living Organisms: Evidence for a New Theory of Transformation discusses traditional interpretations of evolution with a new assumption. The book presents a rational and general account of real evolutionary phenomena based on paleontology and molecular biological data. The text reviews biological evolution from the simple to the complex or progressive and regressive evolution. The author explains the appearance of types of organization from Captorhinomorphs to Pelycosaurs to the Theriodonts— from which the mammals arose. He also explains that in the evolution to mammals, the transformation of the Theriodonts concerned only the skeleton, muscles, dentition, and not the brain. He cites the case of the Perissodactyls as an example. The author also asserts that paleontology and molecular biology can explain the mechanism of evolution without even detailing the causes of orientations of lineages, of the finalities of structures, of living functions, and of cycles. But this approach will involve metaphysics. This book can be appreciated by anthropologists, researcher and scientists involved in zoology, paleontology, genetics and biochemistry.

    • 1 Edición
    • Robert J. Rosen
    • Inglés
    Foundations of Mathematical Biology, Volume III, is devoted to the treatment of behavior of whole organisms and groups of organisms. The viewpoint taken throughout the book is a holistic, phenomenological one. That is, the integrated behavior of these organisms and groups of organisms is not, in general, referred back to specific structural properties of interacting subunits (as in a reductionist scheme), but is rather treated on its own terms without invoking the properties of lower levels of organization. The book begins with an overview of organization and control in physiological systems, with emphasis on the mathematical techniques involved in more detailed investigations of specific physiological mechanisms. Separate chapters cover the cardiovascular system, with particular reference to blood flow; gross problems of organic form; a relational overview of physics, biology, and sociology; the automata theory in the context of the central nervous system; and populations of interacting organisms. The final chapter discusses the material presented in the entire work, some of its philosophical presuppositions and implications, and the possibility of constructing a unified theory of mathematical biology.

  • Benign and Pathological Chromosomal Imbalances

    Microscopic and Submicroscopic Copy Number Variations (CNVs) in Genetics and Counseling
    • 1 Edición
    • Thomas Liehr
    • Inglés
    Benign & Pathological Chromosomal Imbalances systematically clarifies the disease implications of cytogenetically visible copy number variants (CG-CNV) using cytogenetic assessment of heterochromatic or euchromatic DNA variants. While variants of several megabasepair can be present in the human genome without clinical consequence, visually distinguishing these benign areas from disease implications does not always occur to practitioners accustomed to costly molecular profiling methods such as FISH, aCGH, and NGS. As technology-driven approaches like FISH and aCGH have yet to achieve the promise of universal coverage or cost efficacy to sample investigated, deep chromosome analysis and molecular cytogenetics remains relevant for technology translation, study design, and therapeutic assessment. Knowledge of the rare but recurrent rearrangements unfamiliar to practitioners saves time and money for molecular cytogeneticists and genetics counselors, helping to distinguish benign from harmful CG-CNV. It also supports them in deciding which molecular cytogenetics tools to deploy.

    • 1 Edición
    • George R. Mangun
    • Inglés
    Cognitive Electrophysiology of Attention explores the fundamental mechanisms of attention and related cognitive functions from cognitive neuroscience perspectives. Attention is an essential cognitive ability that enables humans to process and act upon relevant information while ignoring distracting information, and the capacity to focus attention is at the core of mental functioning. Understanding the neural bases of human attention remains a key challenge for neuroscientists and psychologists, and is essential for translational efforts to treat attentional deficits in a variety of neurological and psychiatric disorders. Cognitive electrophysiology is at the center of a multidisciplinary approach that involves the efforts of psychologists, neuroscientists, neuropsychologists, psychiatrists, and neurologists to identify basic brain mechanisms and develop translational approaches to improve mental health. This edited volume is authored by leading investigators in the field and discusses methods focused on electrophysiological recordings in humans, including electroencephalograp... (EEG) and event-related potential (ERP) methods, and also incorporates evidence from functional magnetic resonance imaging (fMRI). Cognitive Electrophysiology of Attention illuminates specific models about attentional mechanisms in vision, audition, multisensory integration, memory, and semantic processing in humans.

    • Inglés
    Gene therapy as a treatment for cancer is at a critical point in its evolution. Exciting new developments in gene targeting and vector technology, coupled with results from the first generation of preclinical and clinical studies have led to the design and testing of new therapeutic approaches. The Third Edition of Gene Therapy of Cancer provides crucial updates on the basic and applied sciences of gene therapy. It offers a comprehensive assessment of the field including the areas of suicide gene therapy, oncogene and suppressor gene targeting, immunotherapy, drug resistance gene therapy, and the genetic modification of stem cells. Researchers at all levels of development, from basic laboratory investigators to clinical practitioners, will find this book to be instructive. Cancer gene therapy, like cancer therapy in general, is evolving rapidly, testing new concepts, targets and pathways, evoking new technologies, and passing new regulatory hurdles. Its essence, however, has not changed: the hope and challenges of returning altered genes to normal, using targeted gene expression to alter the function of both tumor and microenvironment, and in some cases normal cells, and delivering functionally important genes to specific cell types to increase sensitivity to killing or to protect normal cells from cancer therapies. In some instances, gene therapy for cancer forms a continuum from gene repair through the use of molecularly modified cells; the use of viral and non-viral vector based gene delivery to both tumor and tumor microenvironment; the use of viral and gene based vaccines; and development of new gene-based therapeutics. The unique mechanistically chosen vector platforms are at the heart of this technology because they allow for direct and selective cell death and transient to sustained delivery of vaccine molecules or molecules that affect the microenvironment, vasculature, or the immune response.

    • Inglés
    Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation — recognized as a suitable, long-term strategy — effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM. This book is a useful resource to entomologists, agronomists, horticulturists, and environmental scientists.

    • Inglés
    Disorders of the peripheral nervous system (PNS) are the cause of prominent neurological symptoms including weakness, sensory loss, pain and autonomic dysfunction associated with deficits, morbidity and mortality. These disorders may be primary hereditary or cryptogenic neurologic disorders confined to the PNS or part of the pathology of both the central nervous system and the PNS. Most PNS disorders are secondary to other system disorders and may be responsive to treatment of the primary disease. Important advances have been obtained in several areas including molecular genetics, biochemistry, immunology, morphology and physiology that have enhanced our understanding of the causes and consequences of damage to peripheral nerve. Understanding of both these groups of PNS diseases has greatly expanded over recent years and has led to important advances of treatment both to protect and to repair damages of peripheral nerve. This volume provides an overview of the state-of-the-art of examination, diagnosis and treatment of these very diverse disorders and will be of interest to both the research and clinical neuroscience and neurology communities.

    • Stanislaw Brzychczy + 1 más
    • Inglés
    Mathematical Neuroscience is a book for mathematical biologists seeking to discover the complexities of brain dynamics in an integrative way. It is the first research monograph devoted exclusively to the theory and methods of nonlinear analysis of infinite systems based on functional analysis techniques arising in modern mathematics. Neural models that describe the spatio-temporal evolution of coarse-grained variables—such as synaptic or firing rate activity in populations of neurons —and often take the form of integro-differential equations would not normally reflect an integrative approach. This book examines the solvability of infinite systems of reaction diffusion type equations in partially ordered abstract spaces. It considers various methods and techniques of nonlinear analysis, including comparison theorems, monotone iterative techniques, a truncation method, and topological fixed point methods. Infinite systems of such equations play a crucial role in the integrative aspects of neuroscience modeling.

    • Paul W. Glimcher
    • Inglés
    In the years since it first published, Neuroeconomics: Decision Making and the Brain has become the standard reference and textbook in the burgeoning field of neuroeconomics. The second edition, a nearly complete revision of this landmark book, will set a new standard. This new edition features five sections designed to serve as both classroom-friendly introductions to each of the major subareas in neuroeconomics, and as advanced synopses of all that has been accomplished in the last two decades in this rapidly expanding academic discipline. The first of these sections provides useful introductions to the disciplines of microeconomics, the psychology of judgment and decision, computational neuroscience, and anthropology for scholars and students seeking interdisciplinary breadth. The second section provides an overview of how human and animal preferences are represented in the mammalian nervous systems. Chapters on risk, time preferences, social preferences, emotion, pharmacology, and common neural currencies—each written by leading experts—lay out the foundations of neuroeconomic thought. The third section contains both overview and in-depth chapters on the fundamentals of reinforcement learning, value learning, and value representation. The fourth section, “The Neural Mechanisms for Choice,” integrates what is known about the decision-making architecture into state-of-the-art models of how we make choices. The final section embeds these mechanisms in a larger social context, showing how these mechanisms function during social decision-making in both humans and animals. The book provides a historically rich exposition in each of its chapters and emphasizes both the accomplishments and the controversies in the field. A clear explanatory style and a single expository voice characterize all chapters, making core issues in economics, psychology, and neuroscience accessible to scholars from all disciplines. The volume is essential reading for anyone interested in neuroeconomics in particular or decision making in general.

  • Toxoplasma Gondii

    The Model Apicomplexan - Perspectives and Methods
    • 2 Edición
    • Louis M. Weiss
    • Inglés
    This 2e of Toxoplasma gondii reflects the significant advances in the field in the last 5 years, including new information on the genomics, epigenomics and proteomics of T. gondii as well as a new understanding of the population biology and genetic diversity of this organism. T. gondii remains the best model system for studying the entire Apicomplexa group of protozoans, which includes Malaria, making this new edition essential for a broad group of researchers and scientists. Toxoplasmosis is caused by a one-celled protozoan parasite known as T. gondii. The infection produces a wide range of clinical syndromes in humans, land and sea mammals, and various bird species. Most humans contract toxoplasmosis by eating contaminated, raw or undercooked meat (particularly pork), vegetables, or milk products; by coming into contact with the T. gondii eggs from cat feces; or by drinking contaminated water. The parasite damages the ocular and central nervous systems, causing behavioral and personality alterations as well as fatal necrotizing encephalitis. It is especially dangerous for the fetus of an infected pregnant woman and for individuals with compromised immune systems, such as HIV-infected patients.
