  • The Foundations of Genetics

    • 1 Edición
    • F. A. E. Crew
    • J. M. Dodd + 1 más
    • Inglés
    The Foundations of Genetics describes the historical development of genetics with emphasis on the contributions to advancing genetical knowledge and the various applications of genetics. The book reviews the work of Gregor Mendel, his Law of Segregation, and of Ernst Haeckel who suggested that the nucleus is that part of the cell that is responsible for heredity. The text also describes the studies of W. Johannsen on "pure lines," and his introduction of the terms gene, genotype, and phenotype. The book explains the theory of the gene and the notion that hereditary particles are borne by the chromosomes (Sutton-Boveri hypothesis). Of the constituent parts of the nucleus only the chromatin material divides at mitosis and segregates during maturation. Following studies confirm that the chromatin material, present in the form of chromosomes with a constant and characteristic number and appearance for each species, is indeed the hereditary material. The book describes how Muller in 1927, showed that high precision energy radiation is the external cause to mutation in the gene itself if one allele can mutate without affecting its partner. The superstructure of genetics built upon the foundations of Mendelism has many applications including cytogenetics, polyploidy, human genetics, eugenics, plant breeding, radiation genetics, and the evolution theory. The book can be useful to academicians and investigators in the fields of genetics such as biochemical, biometrical, microbial, and pharmacogenetics. Students in agriculture, anthropology, botany, medicine, sociology, veterinary medicine, and zoology should add this text to their list of primary reading materials.

    Immunointervention in Autoimmune Diseases is a collection of papers presented at the 1988 International Meeting by the same title, held in Paris, France. This text contains 21 chapters and begins with surveys of the role of antigen in autoimmune responses and the moving boundaries between physiology and pathology of immunity. The succeeding chapters deal with the regulation, immunosuppressive therapy, infections, and immunointervention of autoimmune disorders. These topics are followed by discussions of specific immunosuppressive therapy for a particular disease, including type I diabetes, T-cell leukemia, and systemic lupus erythomatosus. This work also explores the principles of allograft, the use of monoclonal antibody, and OKT3. The remaining chapters consider the maintenance of autoimmunity and the risk/benefit in immunointervention for autoimmune diseases. This book will prove useful to immunologists, pathologists, physiologists, and researchers.

    Specialists from a number of different disciplines have contributed to this book which presents actual basic and applied findings on Fusarium species, on their metabolites and taxonomy, in connection with pathogenicity to cereal plants and potato tubers. Over 100 metabolites produced by Fusaria are described together with results of studies on their occurrence in agricultural products, their metabolism in farm animals, and possibilities of elmination and detoxification during technological processes. Pathogenic Fusarium species are described from the point of view of their taxonomy, profiles of produced metabolites, ecology, pathogenicity and interaction with cereal tissues. Finally, some actual solutions to avoid cereal grain contamination are discussed, mainly in connection with agricultural practices and breeding programmes.The interdisciplinary and comprehensive nature of the book makes it particularly useful to all who are studying or teaching plant pathology, plant breeding, animal nutrition and any other area in which Fusaria and their metabolites play an important role.

    • Inglés
    Virus Structure describes the physical characteristics of isolated viruses that represent typical structural groups, with particular reference to those features analyzed with the aid of the electron microscope. For descriptive purposes, the book has been divided into sections starting with the small icosahedral viruses and leading to the larger and more sophisticated structures, regardless of whether they are animal, plant, or bacterial viruses. These include double-stranded DNA icosahedral viruses, herpesvirus, viruses with helical symmetry, and viruses with complex or a combination of symmetries. Many common architectural features will be found in those viruses selected for discussion in each of the sections, and for these reasons the introduction places some emphasis on the symmetry elements rather than the shapes of viruses. The mechanism by which viruses enter host cells and the events that follow once the cell has been infected are only mentioned briefly as the virus-host interaction is a relatively complex one.

    Hormones provides a comprehensive treatment of human hormones viewed in the light of modern theories of hormone action and in the context of current understanding of subcellular and cellular architecture and classical organ physiology. The book begins with discussions of the first principles of hormone action and the seven classes of steroid hormones and their chemistry, biosynthesis, and metabolism. These are followed by separate chapters that address either a classical endocrine system, e.g., hypothalamic hormones, posterior pituitary hormones, anterior pituitary hormones, ,thyroid hormones, pancreatic hormones, gastrointestinal hormones, calcium regulating hormones, adrenal corticoids, hormones of the adrenal medulla, androgens, estrogens and progestins, and pregnancy and lactation hormones; or newer domains of hormone action which are essential to a comprehensive understanding of hormone action, including prostaglandins, thymus hormones, and pineal hormones. The book concludes with a presentation of hormones of the future, i.e., cell growth factors. This book is intended for use by first-year medical students, graduate students, and advanced undergraduates in the biological sciences. It is also hoped that this book will fill the void that exists for resource materials for teaching cellular and molecular endocrinology and that it will be employed as an equal partner with most standard biochemistry textbooks to provide a comprehensive and balanced coverage of this realm of biology.
