    Receptors of Inflammatory Cells: Structure-Function Relationships is the first in a new serial on Cellular and Molecular Mechanisms of Inflammation. The purpose of this serial is to bring together the latest knowledge in various areas of research in this actively developing field around a topical focus. These volumes are not intended to present comprehensive reviews. Rather, each contribution is meant to be a status report from laboratories actively working in an area. This volume presents an analysis of the structure-function relationships of receptors. It is clear that the structure of receptors provides the initial guidance for numerous functions of each cell in the organism. Through an analysis of the submolecular features of the receptors that are responsible for the initiation of activity of diverse biochemical pathways within the cells, a molecular understanding of the all important initial, guiding events of cell functions will emerge. In the broad sense of cells involved in inflammation, this includes mitogenesis, gene transcription, generation of lipid metabolites and oxidants, clearance of molecules from the surrounding medium, and release of granular constituents from cytoplasmic vesicles into the external medium, among others. The contents of this first volume will serve as a foundation for the subject of the second volume, which is signal transduction. Four additional volumes are in preparation, including Endothelial Leukocyte-Adhesion Molecules, Leukocyte Adhesive Mechanisms in Inflammation and Immunity, a second volume on Signal Transduction, and Stimulation of Inflammatory Cells.

    The Toxicology of Radioactive Substances, Volume 3: Iron-59 deals with the experimental results of tests conducted at the Radiotoxicology Laboratory of the Institute of Occupational Hygiene and Disease, Academy of Medical Sciences, U.S.S.R. The book focuses on studies made on iron-59, which is widely used in science and technology, such as in the metal industry and in the research of hemoglobin metabolism in the bone marrow and red cells. Other studies show, however, that there is a long-term detrimental effect of intake of iron-59. The text then gives a brief outline of the physical, chemical, and biological properties of iron. Research also shows that the body's reaction to radioactive substances depends on how these are transmitted to the body and on their physicochemical properties. The effect of prolonged administration of radioactive iron on the electrical activity of the cerebral cortex of animals is analyzed, of which, possibly, the nervous system is most affected. The book notes also the changes in the red blood cells during chronic administration of iron-59 in small doses, wherein the hemoglobin levels increased temporarily. Studies of prolonged exposure to radioactive isotopes during pregnancy of the test animals show that there are significant changes in erythropoiesis, associated with iron deficiency. In another study, the prolonged internal administration of radioactive substances showed phasic changes in the height of electrocardiographic waves of the test animals. The text is suitable for physicists, nuclear scientists, doctors of toxicology, and researchers in nuclear medicine.

    • Inglés
    The Molecular Properties and Evolution of Excitable Cells describes the theoretical aspects in which excitable cells, such as nerves, muscles, and sense organs, operate. This book develops a hypothesis regarding the evolution and characteristics of excitable cells. This monograph focuses on the properties of the bounding membrane and its complex permeability system, which starts the excitation state. Sense organs, as the input component in both vertebrates and invertebrates, are then discussed. The text then briefly describes the ways that the ionic permeability of the excitable membrane can both be modified and controlled. The book points out that since ions pass through standard sizes of the pores in an excitable membrane, their passage is determined by the dimensions of the pore and by the existing charge found on its walls. The book then explains the application of a mechanical stimulus to a mechanoreceptor that will cause deformations in the membrane. This deformation leads to enzyme activity and produces alteration in the rate at which ATP is supplied to the lateral borders of the cell. The text discusses a hypothesis that invokes enzyme activity by propagating action potential along the axon, and other input systems, such as adrenaline, amino acids, and y-amino-butyric acid (GABA). The book also explains the hypothesis that living organisms are composed of an ordered system of protein-enzymes forming on phospholipid-protein membranes. This monograph will benefit microbiologists, biotechnologists, and academicians connected with the biological sciences.
