    Annual Reports in Organic Synthesis—1970 presents an annual review of synthetically useful information that would prove beneficial to nearly all organic chemists, both specialist and nonspecialist in synthesis. It should help relieve some of the information storage burden of the specialist and should aid the nonspecialist who is seeking help with a specific problem to become rapidly aware of recent synthetic advances. In producing this volume the editors abstracted 47 primary chemistry journals, selecting useful synthetic advances. All reactions and methods which are new, synthetically useful, and reasonably general are included. Each entry is comprised primarily of structures accompanied by very few comments. The purpose of this is to aid the reader in rapidly scanning the book. Chapters I-III are organized by reaction type and constitute the major part of the book. Chapter IV deals with methods of synthesizing heterocyclic systems and concentrates heavily on common, simple systems. Chapter V covers the use of new protecting groups. Chapter VI is divided into two parts and covers those synthetically useful transformations which do not fit easily into the first three chapters. The first part deals only with functional group syntheses. The second part is self-explanatory and involves useful multistep sequences.

  • Lectures in Immunochemistry

    • 1 Edición
    • Michael Heidelberger
    • Inglés
    Lectures in Immunochemistry is a compilation of lectures that would probably never have been put together but for an unusual combination of circumstances. The book includes six lectures given at the behest of Professor Tornio Ogata, Professor of Serology in the Faculty of Medicine at the University of Tokyo. The six lectures were conducted before the Faculty during the period from September 26 to October 6, 1955. No attempt was made to give a course in immunochemistry, since much of the subject was being covered in Professor Ogata's own course in serology. It seemed more profitable, both for the lecturer and his listeners, to select a limited number of topics and to discuss their historical development under the impact of the introduction of quantitative micromethods conforming to the rigorous criteria of analytical chemistry. At the suggestion of Professor Takeo Tamiya, material was included to show how and why certain topics and substances were chosen for the research to be described and discussed. Although the resulting six lectures present an incomplete coverage of the field, they at least bring together a number of scattered fragments into a whole, unified by an experimental approach to the various problems, and by the solution of those problems through the application of quantitative analytical micromethods.

    • Inglés
    Functions of Alternative Terminal Oxidases is a collection of papers from the 11th meeting of the Federation of European Biochemical Societies in Copenhagen in 1977. The book opens with a review of the alternate electron transport mechanism to the main phosphorylating respiratory chain. One paper presents the respiration of mutant stains of Neurospora crassa treated with chloramphenicol that results in three distinct pathways distinguishable by the use of inhibitors. Another paper outlines the testing methods to determine the parameters controlling cyanide-insensitive respiration in Acanthamoeba castellanii and notes the physiological function of this insensitivity. The book then explains that this phenomenon of cyanide-insensitive respiration is common among yeasts, and such pathway of electron transport to oxygen that is insensitive to cyanide or antimycin is well founded in many higher plants and microorganisms. One paper then investigates the terminal oxidases found in two stages in the life cycle of trypanosomes, which cause African sleeping sickness. Another paper notes that a study of the energy metabolism of End. magnusii, a kind of yeast, showed no glucose repression, no alternative oxidation pathway, and no cyanide-insensitive pathway was normally present. The text will be of interest to those whose work involves these organisms, and to researchers, professors, and students whose disciplines are in developmental biology, micro-biology, or cellular biology.

The paper notes that plastic crystals and liquid crystals are different manifestations of the duality of the melting process in molecular crystals, resulting in the loss of positional and orientation order. One paper describes the essential linear defects found in solid crystals, which have been researched in terms of the major role they play in macroscopic properties, particularly plasticity, as the defects or dislocations of translation. G. Friedel's work classifies liquid crystals into an intermediary symmetry composed of the nematic, the cholesteric, and the smectic phases. This intermediary symmetry occurs between the liquid type symmetry and the solid type symmetry. This collection can prove useful for researchers in liquid crystals and industrial scientists in the field of chemistry and polymer composites.

    Teratogens Chemicals Which Cause Birth Defects, 2nd Revised Edition is a collection of papers that discusses the practical aspect of teratogens, particularly regarding information on the teratogenic potential of chemicals. This book describes the principles and mechanism of teratogenesis, including the initiating mechanisms during the subcellular or molecular level and the role of bio-activation in teratogenesis. Investigations have been done on the relationship between spontaneous abortion in women exposed to organic solvents, antineoplastic agents, and chemicals in plastics. Other studies also show that teratogenicity depends in part on enzymatic bio-activation to an embryotoxic reactive intermediate. This text also explains the legal and ethical aspects of fetal protection policies with emphasis on fetal protection. Protection to expecting women extends to pregnant students exposed to teratogenic chemicals in chemistry laboratories. The book explains how and where to get information about the teratogenic potential of chemicals and how to properly handle these chemicals in the laboratory. The book also provides a list from RTECs of toxic chemicals which can cause reproductive effects.

    • Inglés
    Advances in Liquid Crystals, Volume 4 is a collection of papers that deals with liquid crystal sciences, particularly the flow problems in liquid crystals, the effects of high pressure on liquid crystals, lyotropic and thermotropic polymeric liquid crystals, and the light-scattering properties of thermotropic liquid crystals. One paper reviews the continuum theory in flow problems in liquid crystals, presents theoretical predictions, and compares these with associated observations. High-pressure experiments in liquid crystals pave the way for discoveries involving pressure-induced mesomorphism in certain materials, suppression of mesophases, tricritical phase transitions, and re-entrant behavior. Another paper describes the types of macromolecular structures that have a propensity for mesomorphism — linear, conventional types of polymers, such as block copolymers and graft copolymers. Another paper examines the application of light scattering in fluctuations that happens during the liquid crystalline phases. The paper investigates the assumption that light is scattered by inhomogeneities in the dialectric constant of the medium it is passing through. This collection can prove useful for scientists in liquid crystals, and industrial researchers in the field of advanced chemistry and physics.
