  • Adsorption on New and Modified Inorganic Sorbents

    • 1st Edition
    • Volume 99
    • A. Dabrowski + 1 more
    • English
    There has been a lack of authoritative, current information on the structure, investigation and preparation of inorganic sorbents, their numerous applications as well as the adsorption from gaseous and liquid phases on new and chemically modified inorganic solids. This volume deals with the above-mentioned themes and presents 34 up-to-date comprehensive and critical reviews written by well-recognized authorities. The sorbents discussed are primarily mineral ones. Each contribution treats a problem critically by showing its development, presenting documentation on the state-of-the-art and identifying subjects for further research.The book will be of interest to researchers in academic institutes and industrial laboratories engaged in the fields of surface chemistry, inorganic chemistry, adsorption, ion-exchange, catalysis, chromatography and spectroscopy of the surface phenomena, as well as to students attending graduate and postgraduate courses.

  • Cytoskeleton

    • 1st Edition
    • Volume 12
    • J. Hesketh
    • English
    It is now clear from a wide range of research that cytoplasm is not merely a buffered solution of proteins and enzymes but contains a series of complex filamentous structures. The cytoskeleton is the collective term given to these filaments. There is a considerable amount of data available on the protein composition of the major filament systems (microfilaments, microtubules, and intermediate filaments) but we are still comparatively ignorant about the role of the cytoskeleton in cell physiology. However such major cytoplasmic components (actin and tubulin, the monomeric constituents of microfilaments and microtubules, are major cell proteins) must have important roles to play in cell function, and investigations into the functional role of the cytoskeleton currently represent a major area of cell biological research.In recent years rapid advances in molecular biology have begun to influence research on the cytoskeleton. This trend is sure to continue and the techniques of molecular biology and genetics are set to make major contributions to our understanding of the cytoskeleton, as illustrated in this volume by several reviews; the use of transfection techniques by Ben-Ze'ev, the power of Drosophila genetics is described by Fyrberg and the major advances made in the inesin field using molecular approaches as described by Cyr et al. The chapters by Fyrberg and Cyr et al. also illustrate two other areas where major advances in our understanding of the cytoskeleton is occuring; the great array of different motor proteins involved in intracellular movements and the study of the cytoskeleton in developmental biology. Overall, Volume 12 in this series illuminates our increasing knowledge of the important roles of the cytoskeleton in cell function, particularly how it is central to metabolic organization, intracellular transport, interactions with matrix, and nerve function. Our knowledge of the cytoskeleton is now reaching a stage where it is clear that abnormalities in the organization of the cytoskeleton can lead to important clinical manifestations of disease; an example of how such research is now impinging on medical science is presented in the final chapter by Lane on keratin diseases.

  • Advances in Biophysical Chemistry Volume 5

    • 1st Edition
    • BUSH
    • English
    Advances in Biophysical Chemistry, Volume 5, provides reviews of important topics in physical and structural biochemistry. The volume begins with a review of the chemical reactivity of DNA and its relationship to the dynamic nature of DNA conformation and its dependence on base sequence. The underlying chemistry has become extremely important to many researchers who use a host of chemical "footprinting" techniques to study biologically relevant complexes of DNA. This is followed by separate chapters that cover an innovative application of fluorescence energy transfer to investigate the dynamics of complex glycopeptides; the NMR of cations which bind to DNA, providing a picture of DNA conformation and dynamics which is complementary to that provided by 1H NMR spectroscopy; the use of NMR to study electron transfer reactions between cytochrome c peroxidase and cytochrome c; methods for analysis of data on O2 binding by hemoglobin; and experimental methods for obtaining data on protein association.

  • Cell Chemistry and Physiology: Part I

    • 1st Edition
    • Volume 4
    • Edward Bittar
    • English
    This is the first of a 4-volume module that is an introduction to the study of cell chemistry and physiology. It is not intended to be encyclopedic in nature but rather a general survey of the subject with an emphasis on those topics that are central to an understanding of cell biology and those that are certain to become of increasing importance in the teaching of modern medicine.We have followed what appeared to as to be the logical divisions of the subject beginning with proteins. Allewell and her colleagues stress the point that proteins fold spontaneously to form complex three-dimensional structures and that some of them unfold with the help of proteins called chaperones. Michaelis-Menten kinetics are shown by Nelsestuen to describe the behaviour of enzymes in the test tube. The formalism is particularly useful in the search for agents of therapeutic value, as exemplified by methotrexate. Uptake by mammalian cells of substrates and their metabolic conversions are discussed by van der Vusse and Reneman. However, both Welch and Savageau expound the view that the cell is not simply a bagful of enzymes. The biologist is urged by Savageau to abandon Michaelis-Menten formalism and apply the Power Law. The biologist is also told that the approach to arriving at a theory of metabolic control would have to be one of successive approximations requiring the use of the computer. Information gained from comparative biochemistry is shown by Storey and Brooks to have shed new light on mechanisms of metabolic rate depression and freeze tolerance, and to be applicable to organ transplantation technology. We are reminded that enzyme adaptation is partly the result of the presence of a hydrating shell of vicinal water that stabilises conformation of the enzyme. Vicinal water, according to Drost-Hausen and Singleton, lies adjacent to most solids and protein interfaces. The kinks or breaks observed in the slope of the Arrhenius plot are attributed to structural changes in vicinal water. Regulation of cell volume is shown by Hempling to involve regulation of cell water. It could be that the osmo-receptor or volume detection system is a protein that links the cytoskeleton to specific K and C1 channels. Additionally, it is interesting that aquaporins, which are water channel-forming membrane proteins, are now known to exist in both renal and extra-renal tissues. One of the renal porins is affected by vasopressin. We then pass on to protein synthesis (Rattan) and other important topics including protein glycosylation (Hounsell), methylation (Clarke), ADP-ribosylation (Pearson) and prenylation (Gelb). Among the four types of lipids attached to membrane proteins are the prenyl groups. Ford and Gross in their chapter on lipobiology drive home the point that there is an accumulation of acyl carnitine and lysophospholipids during myocardial infarction.

  • Cellular Organelles and the Extracellular Matrix

    • 1st Edition
    • Volume 3
    • Edward Bittar
    • English
    This volume is in two parts. The first contains the remaining chapters on cellular organelles and several chapters relating to organelle disorders. An account of mitochondriopathis is given in the chapter on the mitochondrion rather than in a separate one. The subject matter of this part of the volume shows quite clearly that the interdisciplinary approach to the study of organelles has shed considerable light on the nature of the mechanisms underlying the etiology and pathobiology of many of these disorders. As an example, mutations in the genes encoding integral membrane proteins are found to lead to disturbances in peroxisome assembly. It is also interesting and significant that mistargeting of protein is now thought to be another cause. It will be revealing to see whether mistargeting is the result of mutations in the genes encoding chaperones.The second part of the volume is concerned with the extracellular matrix. It sets out to show that a vast body of new knowledge of the extracellular matrix is available to us. Take for example the integrin family of cell adhesion receptors. It turns out that integrins play a key role not only in adhesion but also in coupling signals to the nucleus via the cytoskeleton. As for fibronectins, they seem to link the matrix with the cytoskeleton by interacting with integrins.Collagen molecules are dealt with in the last two chapters. The boundaries of collagen in disease are defined by drawing a clear line of demarcation between systemic connective tissue disorders (e.g., scleroderma), better known as autoimmune diseases, and the heritable, and the heritable diseases such as osteogenesis imperfect and the Marfan syndrome. This classification takes into account a second group of acquired disorders of collagen forming tissues in which regional fibrosis is the hallmark. Liver cirrhosis and pulmonary fibrosis are prime examples.The decision to place Volumes 2 and 3 before those dealing with cell chemistry was not easily made. It was based on the view that most students will have had an undergraduate course in biochemistry of cell biology or both courses, and that they could go to Volumes 4-7 in which the subject of cell chemistry is covered, and then return to Volumes 2 and 3.

  • Handbook of Industrial Membranes

    • 2nd Edition
    • K. Scott
    • English
    This manual contains necessary and useful information and data in an easily accessible format relating to the use of membranes. Membranes are among the most important engineering components in use today, and each year more and more effective uses for membrane technologies are found - for example: water purification, industrial effluent treatment, solvent dehydration by per-vaporation, recovery of volatile organic compounds, protein recovery, bioseparations and many others.The pace of change in the membrane industry has been accelerating rapidly in recent years, occasioned in part by the demand of end-users, but also as a result of the investment in R&D by manufacturers. To reflect these changes the author has obtained the latest information from some of the leading suppliers in the business. In one complete volume this unique handbook gives practical guidance to using selected membrane processes in individual industries while also providing a useful guide to equipment selection and usage.
