    • Inglés
    The role of the agricultural scientist is to manipulate crop and livestock response phenomena so that they serve society's needs better, enabling countries to obtain full benefit from their agricultural resources. By producing food more efficiently, resources can be made available for non-agricultural development and other needs beyond the essentials of food and fibre. This text provides an introductory outline of the analytical principles involved in appraising the efficiency of crop-fertilizer and livestock-feed response. It provides students of both agricultural science and economics with a simple but formal exposition of the why, how and wherefore of the principles of crop and livestock analysis, thereby helping to further co-operative effort among biological and economic researchers. The third edition has been updated and revised, with additions relating to the principles of modelling, the concept of economic duality as pertinent to response processes, the appraisal of aggregate response, and the economics of response research.

    • Inglés
    Learning and Memory: A Biological View is a comprehensive textbook about the neurobiology of learning and memory. Topics covered include developmental approaches to the memory process; anatomical correlates of neuronal plasticity; drugs that modulate learning and memory; and biochemical correlates of learning and memory. The link between aging and memory is also discussed, along with electrophysiological approaches to the study of memory. Comprised of 12 chapters, this book begins with a review of historical traditions that influenced research on the biological basis of learning and memory. Experimental findings suggesting that the engram for a simple classically conditioned skeletal response may be in the cerebellum are also presented. The next chapter emphasizes the importance of anatomical mechanisms that could mediate learning, plasticity, and memory storage in young and adult animals. Subsequent chapters explore the influence of peripheral hormones and particularly opioid peptides on complex behavior such as learning and memory; the contribution of individual neurotransmitter systems to learning; the psychopathology of aging; and long-term potentiation as a model of the way the central nervous system stores information. Learning in complex vertebrate systems and direct stimulation of various brain nuclei are also examined. The final chapter presents a neurobehavioral analysis of the structure of memory formation that utilizes lesions and explores human memory pathology. This monograph is intended for advanced undergraduate students, graduate students, and research workers in the field of memory.
  • T and B Lymphocytes: Recognition and Function

    • 1 Edición
    • Fritz Bach
    • Inglés
    T and B Lymphocytes: Recognition and Function is the 16th volume of the 1979 ICN-UCLA Symposia on Molecular and Cellular Biology. This book is organized into seven sections, encompassing 74 chapters that summarize molecular level progress in the field of immunobiology. It emphasizes cell membrane, techniques developed for its analysis, and varied products of the major histocompatibility complex, as well as other receptors on cells of the immune system. The book starts by describing two approaches for molecular association evaluation. First is the use of artificial membranes or lipid vesicles for the incorporation of antigens for recognition by T-lymphocytes both at the afferent and efferent levels. Second is the chemical crosslinking of cell surface components with a variety of different crosslinking reagents. This is followed by a discussion on the molecular nature of a T-cell receptor that provides insights of the target(s) recognized by T-lymphocytes. Several chapters discuss data dealing with the issue of the apparent differential recognition by T- and B-cells while both use the same VH genes. Antiidiotypic sera, together with the activity of ""regulator"" T-cells, are also discussed, with regard to their role in networks of regulation of the immune response. This book presents works demonstrating that human T-lymphocytes can also be cloned and both noncytotoxic proliferating T-lymphocytes and Tc can be so obtained. This is along with the continuing studies regarding heterogenity of B-lymphocytes as well as macrophages. Part V focuses on the interaction between lymphocyte and virus and molecular modifications of viral-infected cells. The subsequent section deals with recognition, reactivities, and function of T- and B-lymphocytes. Considerable chapters in this section discuss T-cell cytotoxicity, dichotomy of MHC control over anti H-Y cytotoxic T-cell responses, mouse alloantibodies, and mixed lymphocyte reactions. The concluding part describes immunological tools, such as synthetic membranes and cloned T-cells with biological function.
