This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Download or read book Apoptosis in Immunology written by Guido Kroemer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any movement of their life, immune cells, especially T and B lymphocytes, are confronted with an essential choice: to continue their existence or to commit a sort of metabolic suicide that is referred to as apoptosis or programmed cell death. In contrast to most philosophers, lymphocytes and their precursors are constantly susceptible to suicide, and it even appears that the usual cause of T or B cell elimination is suicide rather than death from natural causes, accidents or murder. This book provides a vast overview of lymphocytes suicide: external triggers and internal motives leading to suicidal impulses, accomplices in self-destruction, weapons implicated in self-execution, removal of dead bodies and pharmacological prevention of suicide. Most of the chapters in this book are devoted to the physiology of apoptosis. The goal is to unmask the external triggers of apoptosis, unravel the signal transduction pro cesses involved therein and describe the role of oncogenes, "death genes" and effector molecules in the apoptotic cas cade. The remaining chapters deal with the pathophysiologi cal aspects of lymphocyte apoptosis, namely, as a host contribution to HIV-induced lymphopenia, and therapeutic strategies for the avoidance of lymphocyte death. We are confident that this compendium will contribute to the exploration of cellular suicide, not only from a basic scientist's viewpoint but also with regard to the possible clinical implications of apoptosis (dys)regulation. Far from having a depressing effect on the reader, cellular suicide may thus provide a source of both intellectual excitement and therapeutic inspiration.

Download or read book Variation and Evolution in Plants and Microorganisms written by National Academy of Sciences and published by National Academies Press. This book was released on 2000-10-11 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.

Download or read book The Origin and Evolution of Eukaryotes written by Patrick J. Keeling and published by . This book was released on 2014 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: All protists, fungi, animals, and plants on Earth are eukaryotes. Their cells possess membrane-bound organelles including a nucleus and mitochondria, distinct cytoskeletal features, and a unique chromosome structure that permits them to undergo mitosis or meiosis. The emergence of eukaryotic cells from prokaryotic ancestors about 2 billion years ago was a pivotal evolutionary transition in the history of life on Earth. But the change was abrupt, and few clues exist as to the nature of the intermediate stages. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology examines evolutionary scenarios that likely led to the emergence and rapid evolution of eukaryotes. Contributors review the mechanisms, timing, and consequences of endosymbiosis, as well as molecular and biochemical characteristics of archaea and bacteria that may have contributed to the first eukaryotic lineage. They explore all of the available evidence, including clues from the fossil record and comparative genomics, and formulate ideas about the origin of genomic characteristics (e.g., chromatin and introns) and specific cellular features (e.g., the endomembrane system) in eukaryotes. Topics such as the origins of multicellularity and sex are also covered. This volume includes discussion of multiple evolutionary models that warrant serious attention, as well as lively debate on some of the most contentious topics in the field. It will thus be fascinating reading for evolutionary biologists, cell and molecular biologists, paleobiologists, and all who are interested in the history of life on Earth.

This book was released on 1997 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992 a Concerted Action Programme (CAP) was initiated by Peter Sijmons with the purpose of intensifying collaborations between 16 European laboratories working on plant-parasitic nematodes. The four-year programme entitled Resistance Mechanisms Against Plant-Parasitic Nematodes focused on molecular aspects of the interaction between sedentary nematodes and plants on the model system Arabidopsis and on novel resistance strategies. Funding was provided mainly for exchange visits between collaborating laboratories and for the organization of annual meetings. During the last annual meeting which was held in May 1996 in Toledo, Spain, Carmen Fenoll initiated the production of this volume.

Download or read book When Cells Die written by Richard A. Lockshin and published by Wiley-Liss. This book was released on 1998-04-13 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Cells Die A Comprehensive Evaluation of Apoptosis and Programmed Cell Death Edited by Richard A. Lockshin, Zahra Zakeri, and Jonathan L. Tilly Cell death is fast becoming one of the most dynamic areas of biological research -involving as it does the study of apoptosis and programmed cell death and the role these phenomena play in development and homeostasis on the one hand, and aging and disease on the other. The profound implications for medicine and agriculture from the manipulation of these processes have spawned a deluge of research papers, articles, approaches, and methods -making it difficult for scientists to get an overview of the field. When Cells Die establishes a coherent framework for the study of cell death -cutting across viewpoints and disciplines and consolidating disparate research efforts. Leading international researchers describe a wide range of topics, including evaluation methods for programmed cell death and apoptosis in numerous tissues and circumstances; genetic mechanism, signal transduction, and observed manifestations of physiological cell death; model systems ranging from nematodes to humans; relevant work in cancer research, AIDS, immune disorders, fertility, eye disease, and Alzheimer's disease; and more. Written to provide an in-depth overview of cell death, the book is divided into five major parts: * The phenomenon of cell death * Themes and approaches to cell death * Cell death where mitosis is high and evanescence is desirable * Cell death in long-lived cells * The clinical relevance of apoptosis. When Cells Die offers a comprehensive introduction to an intriguing discipline, insight into areas in need of exploration, and information on new techniques and therapeutic applications -all supported with diagrams and flowcharts and a fully cross-referenced and indexed text. It is important reading for anyone working in cell and developmental biology, neuroscience, immunology, cancer research, and virology. It is also useful for advanced undergraduate and graduate-level students, postdoctoral fellows, and researchers just entering the field.
