  • Origins of Resistance to Toxic Agents

    • 1 Edición
    • M Sevag
    • Inglés
    Origins of Resistance to Toxic Agents contains the proceedings of the Symposium held in Washington, D.C. on March 25-27, 1954. Contributors theoretically explore the origins of drug resistance and related problems, based on the concept that the development of resistance to various toxic agents is associated with alterations and/or loss in enzyme proteins, and can explain the mutational and other processes. This text is organized into five sections encompassing 25 chapters and begins with an overview of the evolutionary aspects of resistance to antibacterial agents, herbicides, and insecticides. The book then discusses spontaneous and induced mutations to drug resistance in Escherichia coli, along with the mechanism of drug resistance in protozoa and bacteria, the physiological aspects of insect resistance to insecticides, and the enzymatic detoxication of DDT. The next chapters focus on the origins of tolerance and addiction to drugs and the problem of alcoholism; biochemical effects of narcotics and alcohol administration; tolerance and physical dependence to narcotics; and resistance and dependence in cancer cells. The book concludes by analyzing the significance of protein configuration to the specificity of biological interaction. This book is a valuable source of information for physicians, biochemists, pharmacologists, entomologists, plant physiologists, students of cancer, and those who are interested in the theory of the evolution of living matter.

  • Transport And Diffusion Across Cell Membranes

    • 1 Edición
    • Wilfred Stein
    • Inglés
    Transport and Diffusion across Cell Membranes is a comprehensive treatment of the transport and diffusion of molecules and ions across cell membranes. This book shows that the same kinetic equations (with appropriate modification) can describe all the specialized membrane transport systems: the pores, the carriers, and the two classes of pumps. The kinetic formalism is developed step by step and the features that make a system effective in carrying out its biological role are highlighted. This book is organized into six chapters and begins with an introduction to the structure and dynamics of cell membranes, followed by a discussion on how the membrane acts as a barrier to the transmembrane diffusion of molecules and ions. The following chapters focus on the role of the membrane's protein components in facilitating transmembrane diffusion of specific molecules and ions, measurements of diffusion through pores and the kinetics of diffusion, and the structure of such pores and their biological regulation. This book methodically introduces the reader to the carriers of cell membranes, the kinetics of facilitated diffusion, and cotransport systems. The primary active transport systems are considered, emphasizing the pumping of an ion (sodium, potassium, calcium, or proton) against its electrochemical gradient during the coupled progress of a chemical reaction while a conformational change of the pump enzyme takes place. This book is of interest to advanced undergraduate students, as well as to graduate students and researchers in biochemistry, physiology, pharmacology, and biophysics.

    • Hugh McKenzie
    • Inglés
    Milk Proteins: Chemistry and Molecular Biology, Volume I discusses the structure of evolution and biological function of milk proteins and enzymes. The milk proteins arise from a specific mammalian adaptation, and their study is important in its own right. However, the properties of milk proteins are such that their study has attained considerable importance in protein chemistry. In order to have a proper appreciation of the properties of milk proteins, this volume provides a general perspective and strategy for their study. This book is divided into three parts. Part A focuses on the historical survey of milk proteins, its comparative examination and characterization, and study of its immunological and allergenic reactions. Parts B and C discuss the basis of chemical and physical approaches most appropriate to the investigation of milk proteins. This publication is recommended to protein chemists and biochemists working in other areas. It will also serve as a good reference for advanced undergraduate and graduate students of milk protein chemistry.
