Molecular Approaches to Immunology is the 9th volume of the series ""Miami Winter Symposia"". This volume presents papers that cover various aspects about cellular and modern immunology. Cellular immunology deals with the interactions of cells and molecules of the immune system and how these interactions help eliminate pathogens. The main goal of this book is to discuss and provide basic assumptions, approaches, and direction about the advances in the research of immunological science. In relation to this, the chapters of the book examine the recognition of antigen by T-lymphocytes, the role of cell interactions in determining the immune responsiveness, and the concepts behind clonal selection. The book also explains the different genes coding used for antibodies and the characterization of cell surface receptors at molecular level. Furthermore, it examines the evidences for genetic restrictions in cell interactions and the chemical properties of thymosin used in physiological studies. Discussions on the immunoregulation and immunological tolerance by T cells and the growth control of mammalian cells are also presented in this volume. This compilation will be invaluable to biologists, medical practitioners, professors, and students.

Intracellular Parasitic Protozoa introduces the basic structure and classification of intracellular parasitic protozoa and the concept of parasitism. This book starts by discussing the concept of parasitism and the taxonomic background of various intracellular protozoan organisms. This is followed by a description of the relationships between intracellular protozoan and their host cells. Then, this book discusses the ultrastructure of cells and organisms, emphasizing cell morphology that serves as the primary basis of generalizations of the host cell-parasite relationships. It also presents the intracellular protozoa in several groups according to their probable taxonomic relationships and more obvious morphological similarities. Finally, this text describes protozoan fine structure, along with a brief discussion of their biological aspects. This book is ideal for researchers, teachers, and students who wish to gain more knowledge in parasitism caused by intracellular protozoa.

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.

Aspects of Nuclear Structure and Function deals with various aspects of nuclear structure and function and covers topics ranging from the ultrastructure of the female gamete to the structure, biochemistry, and functions of the nuclear envelope. Banding patterns in chromosomes, histones and nonhistone proteins, and the transfer of genetic information in polytene cells are also discussed. This book is comprised of six chapters and begins by presenting a comparative view of some aspects of the ultrastructure of the vegetative (growth) aspects of oogenesis, with emphasis on microtubules, intercellular bridges of differentiating oocytes, and vitellogenesis as well as accessory structures of the egg envelope. The following chapters explore the structure, biochemistry, and functions of the nuclear envelope; banding patterns in chromosomes; chromosomal proteins (histones and nonhistone proteins); transfer of genetic information in polytene cells; and the intracellular biology of DNA polymerases in eukaryotic cells, their association with the nucleus, and how this association changes during the mitotic cell cycle. The relationship between eukaryotic DNA polymerases and DNA replication is also examined. This monograph should be a valuable resource for biochemists.

Ecology of Halophytes documents the proceedings of a symposium on the ecology of halophytes sponsored by the Physiological Ecology section of the Ecological Society of America, and held as a portion of the American Institute of Biological Sciences meetings in August 1972. The book considers the fundamentals of distribution, anatomy, and physiology of halophytes. It provides an overview of the role of the halophyte in ecosystems in various parts of the world. A section on habitat associations of halophytes considers the relation of the plants to other fauna and flora in natural systems. A final section deals with recent applied research related to halophytes and quantification of the impact of man on the ecology of halophytes. This text will be useful for various disciplines working in saline wetlands ecosystems. It is intended to serve land use planners, federal and state natural resources and transportation interests, and real estate developers in providing a comprehensive summary of the ""state of the art"" in understanding halophytic ecosystems. With a better fundamental knowledge of the system, the above mentioned professionals should be better able to plan activities and uses compatible with the natural halophytic ecosystem and avoid some of the past errors man has made.
