  • Cytogenetics of Cells in Culture

    • 1 Edición
    • R. J. C. Harris
    • Inglés
    Cytogenetics of Cells in Culture is a compendium of papers that deals with techniques to detect patterns of DNA replication, cellular control mechanisms, and chromosome analyses with automated instrumentation. Some papers discuss the effects of cell hybridization and of noxious substances such as radiation, chemical agents, and viruses on chromosomal patterns. Other papers focus on the influence of altered chromosomal complement on the survival of cells to long-term tissue culture or to ionizing radiation treatment. A couple of papers points out that naturally occurring chromosomal abnormalities in mammalian populations are relatively rare and are not necessarily associated with physical defects or disease. One paper notes that chromosomes in cells with different functions have different patterns of replication in which the changes are small and hidden. The chromosomes will usually be neutralized showing little of the characteristic pattern of replication or condensation during the early cleavage stages, that will later change into differentiated characteristic ways for each tissue type. Another paper describes chromosome breakage associated with viruses and DNA inhibitors. The compendium can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in the study of cellular biology or physiology.

  • Neurobiology of Social Behavior

    Toward an Understanding of the Prosocial and Antisocial Brain
    • 1 Edición
    • Michael Numan
    • Inglés
    Social neuroscience is a rapidly growing, interdisciplinary field which is devoted to understanding how social behavior is regulated by the brain, and how such behaviors in turn influence brain and biology. Existing volumes either fail to take a neurobiological approach or focus on one particular type of behavior, so the field is ripe for a comprehensive reference which draws cross-behavioral conclusions. This authored work will serve as the market’s most comprehensive reference on the neurobiology of social behavior. The volume will offer an introduction to neural systems and genetics/epigenetics... followed by detailed study of a wide range of behaviors – aggression, sex and sexual differentiation, mating, parenting, social attachments, monogamy, empathy, cooperation, and altruism. Research findings on the neural basis of social behavior will be integrated across different levels of analysis, from molecular neurobiology to neural systems/behavioral neuroscience to fMRI imaging data on human social behavior. Chapters will cover research on both normal and abnormal behaviors, as well as developmental aspects.

  • Cell Growth and Cell Division

    • 1 Edición
    • R. J. C. Harris
    • Inglés
    Cell Growth and Cell Division is a collection of papers dealing with the biochemical and cytological aspects of cell development and changes in bacterial, plant, and animal systems. One paper discusses studies on the nuclear and cytoplasmic growth of ten different strains of the genus Blepharisma, in which different types of nutrition at high and low temperatures alter the species to the extent that they became morphologically indistinguishable. The paper describes the onset of death at high and low temperatures as being preceded by a decrease in the size of the cytoplasm and a corresponding decrease in the size of the macronucleus. The moribund organisms, still possessing structure, are motionless with no distinguishable macronuclear materials. Another paper presents the response of meiotic and mitotic cells to azaguanine, chloramphenicol, ethionine, and 5-methyltryptophan. The paper describes the failure of spindle action, arrest of second division, inhibition of cytokinesis, aberrant wall synthesis, and alterations in chromosome morphology in meiosis cells. In the case of mitosis, a single enzyme—thymidine phosphorylase—shows that reagents which inhibit protein synthesis also inhibit the appearance of that enzyme if the reagent is applied one day before it normally appears. Other papers discuss control mechanisms for chromosome reproduction in the cell cycle, as well as the force of cleavage of the dividing sea urchin egg. The collection can prove valuable for bio-chemists, cellular biologists, micro-biologists, and developmental biologists.

  • The Interpretation of Ultrastructure

    • 1 Edición
    • R. J. C. Harris
    • Inglés
    The Interpretation of Ulstrastructure is a collection of papers dealing with techniques in ulstrastructural research such as in fixation, reversed staining, ultrastructure in embryos and in plants, control of observations by light microscopy, and cytochemistry at the electron microscope level. One paper describes various fixatives used on rat liver tissue including a standard osmium tetroxide solution, pure melted osmium tetroxide, and strong osmium tetroxide solutions in carbon tetrachloride. Another paper points out that the use of electron micrographs of the cell nucleus and chromosomes should include approaches to chromosome analysis. For the investigator studying the three dimensional organization of chromosomes, his approaches should include classical cytology and cytogenetics, chemical and cytochemical studies on nuclei, as well as chemical and physical analysis of nucleic acid and nucleoprotein molecules. Several papers discuss the study of natural and artificial DNA-plasma by thin sections, an assessment of negative staining techniques for revealing ultrastructure, and other approaches in the study of biological ultrastructure by high-resolution electron microscopy. The collection will benefit microbiologists, biotechnologists, and academicians connected with the biological sciences.

  • Advances in Planar Lipid Bilayers and Liposomes

    • 1 Edición
    • Volumen 20
    • Inglés

  • Differentiation and Immunology

    Symposia of the International Society for Cell Biology, Vol. 7
    • 1 Edición
    • Katherine Brehme Warren
    • Inglés
    Differentiation and Immunology is a collection of papers that deals with molecular specificity—the link between immunology and differentiation. One paper reviews the status of regulation in bacteria or viruses, and extends the results to animal cells. The paper also investigates a single aspect of the control of immunoglobulin through the use of plasmacytomas. Another paper discusses the role of macrophages in the minimum theory to possibly account for the energetics of the reaction with receptors, or to the frequency of antigen-sensitive cells. Some papers investigate the immunogenic function of macrophages, the transition from monocyte to macrophage, the factors influencing the formation of macrophage lysosomes, and the origin of macrophage lysosomes. Other papers also discuss the immune response as a model system for studies on cellular differentiation, as well as the differentiation for collagen synthesis in cultured cells. One paper suggests that in differentiation, the changes that can occur in the properties of protozoan cells, perpetuated for long periods, are reversible, and can be a means for survival—as every cell line is also capable of being a germ line. This collection can prove valuable to bio-chemists, cellular biologists, micro-biologists, developmental biologists, and scientists involved in immunology research.

  • Natural Hosts of SIV

    Implication in AIDS
    • 1 Edición
    • Aftab A. Ansari + 1 más
    • Inglés
    Natural Hosts of SIV: Implications in AIDS thoroughly reviews the possible mechanisms by which African nonhuman primate natural hosts of lentiviruses remain essentially disease-free while other hosts exhibit disease and death. The book ultimately indicates directions for further research and potential translations of this compelling phenomenon into novel approaches to treat and prevent HIV. When Asian non-human primate non-natural hosts are experimentally infected with viruses isolated from African species, disease and death normally results. Meanwhile, these African nonhuman primate natural hosts maintain similar levels of plasma and cellular viremia and exhibit compellingly different, essentially disease-free, states. This work attempts to answer the question of how the natural host remains disease resistant.
