Book Description
Metal Ions in Biological Systems is devoted to increasing our understanding of the relationship between the chemistry of metals and life processes. The volumes reflect the interdisciplinary nature of bioinorganic chemistry and coordinate the efforts of researchers in the fields of biochemistry, inorganic chemistry, coordination chemistry, environmental chemistry, biophysics, pharmacy, and medicine. Volumes deal with such topics as the formation, stability, structure, and reactivity of biological compounds of low and high molecular weight containing metal ions; the metabolism and transport of metal ions and their complexes; and new models of complicated natural structures and processes. Volume 21 describes the underlying theories of nuclear magnetic resonance (NMR), promoting a wider use of NMR in studies of paramagnetic species. In six concise chapters by leading international authorities, Applications of Nuclear Magnetic Resonance to Paramagnetic Species outlines the most recent developments regarding the use of nuclear relaxation as a source for structural information ... examines studies of magnetically coupled metalloproteins and metal-porphyrin induced dipolar shifts for conformational analysis ... and evaluates the potential of paramagnetic ions as agents for enhancing NMR image contrast. With over 500 references that facilitate further research, Applications of Nuclear Magnetic Resonance to Paramagnetic Species is an essential resource for scientists and students in such disciplines as biophysics; bioinorganic, inorganic, and coordination chemistry; biochemistry; molecular biology; and enzymology.

Book Description
Volume 9 of Chemical Mutagens consists mainly of chapters discussing the development and validation of short-term assays to detect the mutagenic effects of environmental chemicals. These chapters include an assay with the grasshopper neuroblast, a comparison of mutagenic responses of human lung-derived and skin-derived diploid fibroblasts, a forward-mutation assay in Salmonella, a multigene sporulation test in Bacillus subtilis, a specific locus assay in mouse lymphoma cells, a study of the induction of bacteriophage lambda, and the granuloma pouch assay. In addition, there are two chapters on the identification of mutagens in cooked food and in human feces.

Book Description
This directory is a comprehensive guide to the toxicity of over 1000 polymers, monomers and additives used by the rubber and plastics industries. Since the toxic properties of materials are determined by the toxic properties of the substance released by them, a significant proportion of the book deals with monomers, plasticisers, stabilisers, and other additives. In this regard, the book will be of use when assessing the toxic properties not only of existing materials but also of future materials containing components that have already undergone toxicological analysis. Each entry gives a brief description of the material and its uses followed by summaries of studies on its toxicity. Extensive references are included for those requiring further details on the tests and results. The handbook is intended as a reference work and will provide a valuable reference work for all those involved with health and safety in the rubber and plastics industries. "This publication is a translation of a Russian text. As a consequence, the polymers and additives are not strictly in English alphabetical order."

Book Description
"Zoological Record is published annually in separate sections. The first of these is Comprehensive Zoology, followed by sections recording a year's literature relating to a Phylum or Class of the Animal Kingdom. The final section contains the new genera and subgenera indexed in the volume." Each section of a volume lists the sections of that volume.
