  • Humoral Control of Growth And Differentiation

    Vertebrate Regulatory Factors
    • 1 Edición
    • Joseph Lobue
    • Inglés
    Humoral Control of Growth and Differentiation, Volume I: Vertebrate Regulatory Factors is a part of two-volume work that introduces the reader to humoral control of growth and differentiation in vertebrates. This volume gives emphasis on chemical messengers, which have received relatively little attention in standard treatises on endocrine physiology for a number of reasons. Organized into three parts, this book begins with the physiological significance of chalones. This class of hormones is intimately associated with mitotic homeostasis as inhibitors of cell division. The book then looks into the aspects of blood cell formation and release, as well as the humoral control of organs and tissue growth. This volume also includes chapters discussing the humoral changes occurring in diseases of the blood and other pathologic states. The humoral factors influencing lymphocyte proliferation in culture are also explained. Moreover, this volume examines the effects of the more orthodox hormones upon skeletal growth and regeneration.

  • The Developmental Biology of Reproduction

    • 1 Edición
    • Clement Markert
    • Inglés
    The Developmental Biology of Reproduction documents the proceedings of the 33rd symposium of the Society for Developmental Biology. Reproductive Biology was selected as the main theme of the symposium. The symposium aimed to draw center attention on basic aspects of reproduction in both plants and animals in the hope of stimulating research that might provide the necessary foundation for effective, practical control of human reproduction. Five areas were selected for emphasis: the formation of eggs and sperm; the activation of the egg to develop into an embryo; the genetic and biochemical events underlying the early development of the embryo; the hormonal controls operating in the reproductive process; and the general control of implantation and growth of the mammalian embryo in the uterus. Thirteen reports were given by distinguished researchers in each of these areas. All biologists interested in a broad understanding of problems of reproduction will find this symposium interesting and important for their own work.

    • Inglés
    Inhibition and Destruction of the Microbial Cell focuses on the effects of various classes of toxic chemical agents on microbial cell. This book is organized into 14 chapters that cover the topics from two points of view: the agent and the target (the microbial cell). The introductory chapters are devoted to the inhibitory effects of elevating temperature and to the lethal effect of environmental thermal energy supply restriction on growing bacteria. A chapter focuses on the effect of various classes of antibacterial compounds, such as 4-amino-quinaldinium and 8-hydroxyquinoline derivatives, chlorhexidine, amidines, halogens, dyes, and nitrofurans. The subsequent chapters examine the effects of other chemical agents on microorganisms, including toxic gases, solutes, ions, and radiations. The book goes on examining the inhibition and destruction of specific microorganisms, such as Pseudomonas aeruginosa, Enterobacteriaceae, Mycobacteria, Cocci, bacterial spores, molds, yeasts, and viruses. The last chapter discusses the effect of the cultural prehistory of microorganisms upon their response to inhibition and destruction. This book is an invaluable resource for graduate research workers and scientists in pure and applied microbiology. This will also be a good reference for undergraduates reading specialized courses at honors level in microbiology or applied courses in food science and agriculture. Furthermore, it will be of interest to the medical profession, especially those involved in public health and pathology, as well as to scientists in the pharmaceutical industry.

  • Acidic Proteins of the Nucleus

    • 1 Edición
    • Ivan Cameron
    • Inglés
    Acidic Proteins of the Nucleus focuses on the functional role of acidic nuclear proteins in differential gene expression. Historically, these proteins are referred to as acidic in nature because they are insoluble in dilute mineral acids and their amino acid composition shows a preponderance of acidic over basic amino acid residues. After an introduction to DNA-binding proteins and transcriptional control in prokaryotic and eukaryotic systems, the subsequent chapters describe various approaches for isolating, separating, and characterizing acidic nuclear proteins. The core chapters specifically cover the isolation, fractionation, and characterization of acidic nuclear phosphoproteins, and the role of these proteins in cell proliferation, cell differentiation, and cell cycle. The last two chapters address the role of acidic nuclear protein in binding steroid hormones and in gene regulation. Each chapter contains some previously unpublished work and provides recommendations for future research. This book will be a good reference background for researchers of acidic nuclear proteins.

    Environmental Control of Cell Synthesis and Function presents the proceedings of the Fifth International Symposium on the Continuous Culture of Micro-organisms, held at St. Catherine’s College, University of Oxford, on July 19-24, 1971. It reflects the symposium’s four main areas of interest, namely, kinetics of growth, advances in equipment design and operation, influence of environment on the control of cell synthesis, and physico-chemical effects on cell structure and functioning, and some 20 individual topics. With a strong focus on the influence of chemical and physical nature of the growth environment on the structure and functioning of microbial cell, the book starts by presenting the chemostat theory, its validity, extensions, and future challenges. It goes on to discuss the progress in environmental control of continuous culture, the product formation in continuous culture, and internal and external conditions involved in its control. Chapters 3 to 8 explore the hypertrophic and continuously synchronized growths; mixed culture studies with the chemostat; kinetics of growth on aqueous-oil and aqueous-solid dispersed systems; design and operation improvements of the chemostat; and the role of turbidostat. Chapters 9 to 14 focus on the influence of environmental and cellular factors on cell physiology. The concluding chapters discuss the application of continuous culture to research in microbiology, particularly, to problems of microbial physiology. This book is ideal for microbial researchers, microbial physiologists, and cell biologists who are particularly interested in continuous culture techniques.
