    Rapid advances in chromatographic procedures, spectroscopic techniques and pharmacological assay methods have resulted in the discovery of an increasing number of new and interesting natural products from terrestrial and marine sources. The present volume contains comprehensive reviews on some of the major advances in this field which have taken place in recent years. The reviews include those on: novel metabolites from marine gastropods; the chemistry of marine natural products of the Halenaquinol family; secondary metabolites from Echinoderms and Bryozoans; triterpenoids and aromatic compounds from medicinal plants; chemistry and activity of sesquiterpenes from the genus Lactarius; the chemistry of bile alcohols; antifungal sesquiterpene dialdehydes; annonaceous acetogenins; nargenicin macrolides; and lignans and diarylheptanoids. Tropane alkaloids and phenolides formed by root cultures are also reviewed. Articles on natural Diels-Alder type adducts, the use of computer aided overlay for modelling the substrate binding domain of HLADH, applications of 170 NMR spectroscopy to natural product chemistry and the role of biological raw materials in synthesis are included. Volume 17 provides material of interest to natural products chemists.

  • Subband Compression of Images: Principles and Examples

    • 1st Edition
    • Volume 6
    • T.A. Ramstad + 2 more
    • English
    Sixth in the book series, Advances in Image Communication, which documents the rapid advancements of recent years in image communication technologies, this volume provides a comprehensive exploration of subband coding.Originally, subband coding and transform coding were developed separately. The former, however, benefitted considerably from the earlier evolution of transform coding theory and practice. Retaining their own terminology and views, the two methods are closely related and this book indeed aims to unify the approaches. Specifically, the volume contributes effectively to the understanding of frequency domain coding techniques. Many images from coding experiments are presented, enabling the reader to consider the properties of different coders.Chapter 1 introduces the problem of image compression in general terms. Sampling of images and other fundamental concepts, such as entropy and the rate distortion function, are briefly reviewed. The idea of viewing coding techniques as series expansions is also introduced. The second chapter presents signal decomposition and the conditions for perfect reconstruction from minimum representations. Chapter 3 deals with filter bank structures, primarily those displaying the perfect reconstruction property. Quantization techniques and the efficient exploitation of the bit resources are discussed from a theoretical perspective in Chapter 4 and this issue is further examined in Chapter 6, from a more practical point of view. Chapter 5 provides a development of gain formulas, i.e. quantitative measures of the performance of filter banks in a subband coding context, and these are then employed in a search for optimal filter banks. A number of examples of coded images using different subband coders are presented in Chapter 7, these indicating that subband coders give rise to some characteristic types of image degradations. Accordingly, Chapter 8 presents several techniques for minimizing these artifacts. The theory and practice of subband coding of video, at several target bit rates, is discussed in the last chapter.

  • Sequence Stratigraphy on the Northwest European Margin

    • 1st Edition
    • Volume 5
    • R.J. Steel + 3 more
    • English
    Sequence Stratigraphy, presently one of the most rapidly growing areas in geology, is concerned with the documentation and prediction of how sandstones (potential hydrocarbon reservoirs) and shales (potential source rocks) are distributed in time and space within sedimentary basins. The book takes a critical look at some of the sequence stratigraphy concepts, and provides an account of how these have been applied recently in NW Europe (North Sea, mid Norway and E. Greenland, Barents Sea and Svalbard), mainly in connection with the exploration for oil and gas.There is currently no similar book available.

    • English
    The account in this inaugural volume of the series covers the period 1900 to 1960, but also outlines the principal developments in earlier centuries from which biochemistry emerged. Findings are considered in the light of present knowledge, rather than in a rigid historical framework.

  • Membrane Protein Transport

    • 1st Edition
    • Volume 1
    • S.S. Rothman
    • English
    This is the first volume in a series on membrane protein transfer. Membrane protein transport underlies the topological disposition of many proteins within cells and it is this disposition that allows for the co-ordination of the central cellular processes, such as metabolism.

  • General Principles

    • 1st Edition
    • Volume 1
    • A.G. Lee
    • English
    Progress in understanding the nature of the biological membrane has been very rapid over a broad front, but still pockets of ignorance remain. Application of the techniques of molecular biology has provided the sequences of a very large number of membrane proteins, and has led to the discovery of superfamilies of membrane proteins of related structure. In turn, the identification of these superfamilies has led to new ways of thinking about membrane processes. Many of these processes can now be discussed in molecular terms, and unexpected relationships between apparently unrelated phenomena are bringing a new unity to the study of biological membranes. The quantity of information available about membrane proteins is now too large for any one person to be familiar with anything but a very small part of the primary literature. A series of volumes concentrating on molecular aspects of biological membranes therefore seems timely. The hope is that, when complete, these volumes will provide a convenient introduction to the study of a wide range of membrane functions. This first volume is devoted to general surveys of the structure and synthesis of membrane proteins and lipids, of the interactions between lipids and proteins, and of the functions of biological membranes.

  • The Chemistry and Pharmacology of Taxol® and its Derivatives

    • 1st Edition
    • Volume 22
    • H. Timmerman
    • V. Farina
    • English
    Taxol®, a naturally occurring diterpenoid is one of the most exciting antitumor drugs available today. Its current indications (refractory ovarian and metastatic breast cancer) may soon be expanded since the drug is showing activity against lung and head-and-neck cancers.The book opens with a review of the naturally occurring taxoids, a chapter which is not a comprehensive list of all taxoids isolated to date, but attempts a systematic approact to describing the different classes of taxoids, with particular reference to all skeletal types and the various functionality patterns. Biosynthetic studies are also discussed, as well as some of the basic chemistry and common functionalities of taxoidic skeleton. Structural identification of taxoids, mostly by spectroscopic means; the formulation of taxanes; the metabolism and pharmacokinetics of Taxol® are also discussed, as are the chemistry of taxanes in relation to SAR studies; SAR aspects of the phenylisoserine side chain; and the mode of action of the taxanes and the mechanisms of resistance.The book is therefore written for medical chemists, in order to stimulate further research in this area and to provide the reader with the necessary background information to start a research program in the area.
