The Alkali Metal Ions: Their Role for Life


Book Description

MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e.g., Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.







Cellular Aspects of Membrane Permeability


Book Description

Cellular Aspects of Membrane Permeability describes the state of knowledge on permeability problems and interprets experimental results within the framework of working hypotheses. The book discusses membrane permeability with some biochemical perspective presented to explain the origin and adaptations of animal life. The text explains the process and the driving forces affecting the permeability characteristics of the experimental object. It then discusses the distribution of ions and molecules between two phases separated by a living membrane. Then the text analyzes the chemical nature of the molecular architecture that causes such permeability characteristics. The book addresses the electrical potential profiles of epithelial tissues, and then discusses the conducting membranes. It also explains the relationships between inorganic ions, sugar, amino acids, fatty acids, and bioelectric potentials. The book also explains the physical nature of such chemical nature and structure of living membranes. The text then describes the structure of the cellular surface and the structural organization of the cell. The selection can prove useful for biologists, microbiologists, zoologists, and students and professors of biology and its related disciplines.




Kinetics of Drug Action


Book Description

Most drugs, toxins, hormones, and the like bring about their biologic actions by reacting with specific receptors somewhere in the body. Scientists working in all areas of biologic science have shown increasing interest in the analysis of drug-receptor interactions in the broadest sense. Studies of drugs (binding) to receptors in situ and to isolated and partly purified receptors are becoming common practice. The action of a drug in the body is, however, a kinetic event not only with respect to transport of drug molecules to the environment of the receptors, but also with respect to the drug-receptor interaction itself. Kinetics of Drug Action is an integrative approach to drug transport through the body, membrane transport toward the receptors, and the kinetics of drug receptor interaction. This volume is aimed at providing a critical and penetrating study of the problems relevant to the kinetics or drug action from drug dosage to the final response. It is felt that the critical surveys presented in this volume will contribute significantly to receptor study research in various biologic fields and to a better understanding of drug action. I would like to express my gratitude to our secretary Miss MARGOT JANSSEN for the extensive typing of manuscripts and to our laboratory assistant Miss COBY HURKMANS for her dedicated assistance in the correcting some of the manuscripts and preparating the index.
