    • Inglés
    Molecular Mechanisms in the Control of Gene Expression documents the proceedings of the ICN-UCLA conference on Molecular Mechanisms in the Control of Gene Expression, organized through the Molecular Biology Institute of UCLA, held in Keystone, Colorado, 21-26 March 1976. The conference focused on three topics: the action of repressors on specific nucleotide sequences in DNA; how DNA and histones are intertwined in eucaryotic chromosomes; and in the development of new techniques that appear to lift genes from complex genomes. The volume contains 65 chapters organized into nine parts. The papers in Part I examine the organization of prokaryotic and eukaryotic chromosomes. Part II presents studies on the interaction of RNA a polymerase and regulatory molecules with defined DNA sites. Parts III and IV focus on RNA polymerases of eukaryotes and the regulation of transcription in eukaryotic systems, respectively. Part V contains papers dealing with nucleic acid sequences, transcription, and processing. Part VI covers cellular aspects in the study of gene expression. Part VII takes up cloning while Part VIII is devoted to genetic analysis through restriction mapping and molecular cloning. Finally, Part IX summarizes the recent progress reported at the conference and also indicates some of the limitations that can be placed upon interpretation of data.

Another paper examines the synthetic chemistry of oligosaccharides, particularly, the synthesis of trisaccharides, one of which is a repeating unit of O-antigenic polysaccharide from Salmonella anatum. One paper notes that plant acidic polysaccharides should be classified in terms of their basal core structures to enable groupings and comparisons of glycuronoglycans isolated from various sources. Another paper shows that the structure of the carbohydrate moiety of glycoproteins points to the biological role of carbohydrate moieties as possible cell recognition signals.

    • Inglés
    Ion Transport is a collection of papers from the Smith Kline & French Research "Symposium on Ion Transport" held in Cambridge, on April 12-14, 1989. These papers focus on the plasma membrane, particularly on the three main classes of transporters, namely, pumps, exchangers, and channels. Some papers discuss the different experimental approaches from electrophysiological and ion flux measurements through pharmacology, molecular biology, electrostatics, and computer modeling. Other papers discuss the P-type cation pump, a class of ATP-driven ion pumps, which is determined from its subunit composition and from the results of the hydrolysis of ATP. Several papers explain the techniques used in ion channels and their modulation. These techniques can be used in the voltage-gated Na+ channel or in permeation mechanisms. Other papers examine the transport proteins involved in the physiology of ion transport. Ions and fluid transport relate to, at the molecular level, how ions cross membranes. A minimum model, in conjunction with theoretical perspective, can describe the mechanism by which ions move through channels. This collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in the study of cellular biology or biophysics.

    Nonbenzenoid Aromatics, Volume II, provides an overview of the state of knowledge in the field of non-benzenoid aromatic compounds. The theme that threads its way through the six chapters is that of ""aromaticity,"" with each author making an effort to evaluate this concept in light of his own work. It is with this in mind that this treatise was initiated with an historical account tracing the development of the idea up to the discovery of the electron. The book begins with discussions of the estimation of the thermochemical and kinetic stability of a system which has not yet been synthesized and the calculation of electronic spectra. This is followed by separate chapters on the electron spin resonance (ESR) spectra of radical ions of nonbenzenoid aromatics; the theoretical and empirical bases of exaltation; and treatment of cyclic (4n + 2) π-electron systems with six or more π-electrons and bearing one or more formal charges.

This book opens with an introductory chapter that discusses fundamenta... concepts of the electronic theory of organic chemistry and the relationship of heterocyclic and carbocyclic aromatic compounds. This is followed by separate chapters on the chemistry of the six-membered ring compounds containing one or more heteroatoms, five-membered ring compounds, three- and four-membered rings, and the physical properties of representative heterocyclic compounds. Each chapter begins with introductory section that surveys the various ring types, gives the systems of nomenclature and numbering, and mentions a few important natural and synthetic compounds. Syntheses starting from aliphatic and carbocyclic compounds are then given. The preparation of one heterocyclic compound from another is considered as a reaction of the starting material. The reactions of aromatic and non-aromatic compounds are discussed separately.

    Excited States, Volume 7 is a collection of papers that discusses the excited states of molecules. The first paper reviews the rotational involvement in intra-molecular in vibrational redistribution. This paper analyzes the vibrational Hamiltonian as to its efficacy in detecting the manifestations of intra-molecular state-mixing in time-resolved and time-averaged spectroscopic measurements. The next paper examines the temporal behavior of intra-molecular vibration-rotation energy transfer (IVRET) and the effects of IVRET on collision, reaction, and the decomposition processes. This paper also describes how IVRET can decrease the anisotropy of the angular distribution of photo dissociating molecules that takes longer than the rotational period of disassociation. The third paper explains rotations and electronic decay by focusing on nonresonant light scattering, which is explained in the theory of radiationless transitions, when the exciting light source is included. The last paper shows how sub-Doppler techniques adapted from atomic physics can measure accurately dense rotational triplet structure and singlet-triplet couplings in high vibrational triplet levels. This book will prove helpful for researchers whose work involves physical chemistry or molecular chemistry and physicists involved in atomic or solid-state physics.

    Pesticide Residues: A Contribution to their Interpretation, Relevance and Legislation contains the papers presented at two special Symposia held in the Pesticide Residues Section at the Fourth International Congress of Pesticide Chemistry (lUPAC). This book is organized into two parts encompassing 17 chapters. Part I focuses on the accuracy of any statement on the amount of residue a sample contains, which is influenced by the interaction of multiple factors. This part specifically discusses some of these factors and their bearing on the analytical result of pesticide residue analysis. Part II deals with the complex problem of whether and how the unavoidable uncertainties in analytical findings can be matched to a legislative machinery accustomed to operating with rigid data. This part also covers the principles for the permission of pesticides from the food-hygienic point of view, with emphasis on regulatory toxicology and tolerances of pesticide residues. This book will be of value to toxicologists, agriculturists, public health workers, and legislators.

    • Inglés
    Infrared and Raman Spectroscopy of Lunar and Terrestrial Minerals makes available in a single reference work original descriptions and summaries of the research on infrared and Raman spectroscopy of lunar and terrestrial minerals so that this information will be readily available not only to those researchers in the continuing programs on lunar samples from the completed Apollo series and on the remote sensing of solar system objects, but, in particular, to that much larger group of researchers in government, industry, and universities involved in the many programs on terrestrial minerals and earth sciences by remote sensing. The chapters in this volume are arranged according to spectroscopic technique and/or frequency range rather than application. Thus there are chapters on visible and near-infrared, followed by those on mid-infrared, far-infrared, and Raman spectroscopy. Applications are roughly divided between lunar and terrestrial, although the broad range of interchangeability of applications is obvious in many instances. There are also chapters on remote sensing of space targets and earth sciences; on lunar mineralogy and terrestrial mineralogy and geology; and on structures of lunar minerals and structures of terrestrial minerals.
