Genetic Control of Immune Responsiveness: Relationship to Disease Susceptibility documents the proceedings of an international conference held at Brook Lodge, Augusta, Michigan, May 8-10, 1972. It brings together the detailed experimental evidence on the mechanism of action of specific immune response genes, and shows how the two major classes of immune response genes affect our understanding of basic immunology and antibody formation on the one hand, and of host factors determining disease susceptibility on the other. The book is organized into seven parts that correspond to the seven sessions of the conference. Part I presents a session on how the study of the genetic control of immune responses in guinea pigs and mice has contributed to the development of T cell immunology. Part II presents a session on genetic fine structure of the major (H-2) histocompatibility complex in the mouse. Part III presents a session dealing with the association between the production of homogeneous antibody, or of idiotypic antibody, and immunoglobulin allotypes. Part IV presents a session on the relationship between histocompatibility-linked and allotype-linked immune response genes and antigen-specific receptors on T and B cells. Part V presents a session on animal models of multigenic control of susceptibility to disease. Part VI presents a session on the associations between HL-A type and specific disease entities. Finally, Part VII provides a commentary on the ideas and concepts emerging from the three days of free-ranging discussion.

Progress in Theoretical Biology, Volume 2, brings together the significant and timely theoretical developments in particular areas of biology in a critical and synthetic manner. It is concerned with a field which has emerged as an identifiable subdiscipline of the biological sciences. This emergence and recognition signify that biological science has evolved from its initial stage of description and classification into the adolescence of transformation to the quantitative. The book's opening chapter develops a theory that uses a new generalization of statistical mechanics to provide a basis for understanding how the microscopic behavior of nonliving parts can generate the macroscopic appearance of a living aggregate. The subsequent chapters discuss theoretical methods in systematic and evolutionary studies; the theory of neural masses; the design of chemical reaction systems; cooperative processes in biological systems; and the organization of motor systems. This book is intended for the modern biological scientist as well as for the physical scientist who is inquisitive of the ways of the most complex of all processes.

Mutagenic Effects of Environmental Contaminants investigates the mutagenic consequences of environmental contaminants, such as pesticides, industrials, food additives, drugs, and biologicals, as well as the possible relationships between mutagenesis and carcinogenesis. It describes the monitoring of chemical mutagens in the environment and the ways that genetic mutations cause disease in humans. Organized into 14 chapters, this volume begins with an overview of the current burden of human genetic disease and the biochemical mechanisms of mutation. It then discusses practical and feasible methods that use a variety of organisms to screen potential mutagenic agents, increased mutation rates in human populations, mutagens that are currently used commercially, and the interrelationships between mutagenicity, carcinogenicity, and teratogenicity. The reader is also introduced to genetic toxicology, detection of chemically induced mutations in experimental animals, and chromosome and somatic mutations in humans. This book is a valuable resource for scientists, policymakers, and administrators of environmental programs.

Biology of Halophytes is a monograph on the biological aspects of halophytes and their behavior under saline conditions. It explores the physioecological characteristics of halophytes, such as reproduction, growth, metabolism, water relations, mineral nutrition, salt transport, salt secretion, and salt resistance. It also provides ecological information on higher marine plants, particularly submerged angiosperms, mangroves, and high coast plants. Organized into 16 chapters, this volume begins with an overview of sources of salinity and the development and nature of salines and salt-affected soils. It proceeds with a discussion of the classification of halophytes, their mutual relationships, distribution, and sociology. It also summarizes autecological information on some terrestrial halophytes and introduces the reader to the formative effects of salinity, interrelationships between plants and spatial distribution within the community, ion transport and mineral nutrition, and regulation of salt content of shoots, before concluding with a short review on ecotypic differentiation in halophytes. This book will be a valuable resource for advanced students, as well as teachers of plant and environmental sciences.

Developmental Aspects of the Cell Cycle

Developmental Aspects of the Cell Cycle discusses the molecular, organelle, cellular, and organismal levels of cell cycle, cell proliferation, and cell differentiation. It addresses the possible antagonism between the ability of cells to proliferate and to differentiate. After brief historical, theoretical, and methodological background information for each cell system, this book concentrates on the mechanisms involved in the regulation of cell proliferation and differentiation. The book presents systems in which mass cultures of cells can be induced to undergo a synchronous transition from one cell state to another, enabling the amplification of cellular and biochemical events to be analyzed with the available morphological and biochemical techniques. Some chapters explain the possibility of cell state production by a microenvironment that occurs at the organismal level, in which a series of mitotic and growth steps causes cells proliferation. The concluding chapters discuss cell proliferation and differentiation in specific cell system, such as embryonic chick and male germ cell. This book will appeal to investigators in many disciplines, teachers, and life sciences students, particularly, to molecular, cellular, and developmental biologists.

Investigations in General Biology presents an overview of studies in general biology, including behavior, biological models, cell activities, organization of plants and animals, population genetics, and evolution. The opening chapters deal with the significance of accurate observations of systematic ordering of biological events in plants and animals. The use of laboratory tools for biological analysis and the application of such tools in biological diffusion process are also considered. This book describes the use of model to investigate cellular phenomenon and an application of a valid model of cell membrane function using microscope. The responses in solutions of different concentrations are recorded. Considerable chapters discuss refined experimental approach to testing a biological hypothesis, with emphasis on the idea of using a control. The control indicates the amount of response that occurs due to variables not anticipated. Furthermore, this book discusses the organization of the flowering plant, including those organs involved in maintenance as well as animal organization, particularly, in crayfish and frog. It presents the proper statistical procedures that can be used by geneticist to determine probability genetic ratio. It explains gene frequencies of characters in human populations and consequences of nonrandom reproduction and subsequent departure from Hardy-Weinberg equilibrium. Finally, the concluding chapters deal with physiological attributes and classification of animal and plant population. General biology students and instructors will greatly benefit from this book.
