This book is based on papers presented at the Second International Symposium on Bacterial and Bacteria-like Contaminants of Plant Tissue Cultures held at University College, Cork, Ireland in September 1996, with additional invited papers. Since the first symposium (published as Acta Horticulturae 225, 1988), there have been considerable advances in both plant disease diagnostics and in the development of structured approaches to the management of disease and microbial contamination in micropropagation. These approaches have centered on attempts to separate, spatially, the problems of vertical disease transmission, via infected explants to progeny microplants, from laboratory contamination. Disease control is best achieved by establishing pathogen-free cultures, while laboratory contamination management is based on subsequent good working practice. Control of losses due to pathogens and microbial contamination in vitro addresses, arguably, the most important causes of losses in the industry; nevertheless, losses at and post establishment can also be considerable due to poor quality micro-propagules. In this book, a holistic approach to pathogen and microbial contamination control is evident with the recognition that micropropagators must address pathogen and microbial contamination in vitro, and diseases and microplant failure at establishment. There is increasing interest in establishing beneficial bacterial and mycorrhizal association with microplants in vitro and in vivo. The contents are divided into sections. In each section there are papers that update contributions offered at the first symposium; for example, major advances have been made in microbial taxonomy and diagnosticsbased on advances in DNA-based techniques. Consolidation has occurred in therapy and laboratory contamination management. Novel, and arguably speculative, in vitro contamination control based on autotrophic culture is described; and disease control at establishment using bacterial and mycorrhizal inoculants is discussed.

Animal cell technology is a newly growing discipline of cell biology which aims not only to understand structure, function and behavior of differentiated animal cells but also to uncover their ability useful for industrial and medical purpose. The goal of animal cell technology includes clonal expansion of differentiated cells with useful ability, optimization of their culturing in industrial scale, modulation of their ability for production of pharmaceutical proteins and monoclonal antibodies, and newly application to gene therapy and organ culture. The last seven Annual Meetings of the Japanese Association for Animal Cell Technology (JAACT) had attracted increasing number of participants. At the Eighth Meeting (JAACT'95) held in Iizuka from November 6 through 10, 1995. Before this Meeting, we were all shocked by the sudden death of a founder of JAACT, the late Prof. Hiroki Murakami in February of this year. But we had more than 90 participants from outside of Japan and 170 from Japan in this Meeting. The editors express their sincere gratitude to all researchers who joined the meeting, to the organizers of the Symposium Sessions, to members of the organizing committee who dedicated themselves in assuring the Meeting's success in the absence of Prof. H. Murakami, and the graduates and undergraduates students of Kyushu University and Kyushu Institute of Technology who supported management of the Meeting. We also thank the Japanese Bioindustry Association and Fukuoka Science & Technology Foundation for the financial support.

The book presents a new, powerful model of neuronal networks, consisting of a three-dimensional neuronal culture in which 3D neuronal networks are coupled to micro-electrode-arrays (MEAs). It discusses the main advantages of the three-dimensional system compared to its two-dimensional counterpart, and shows that the network dynamics, recorded during both spontaneous and stimulated activity, differs between the two models, with the 3D system being better able to emulate the in vivo behaviour of neural networks. The book offers an extensive analysis of the system, from the theoretical background, to its design and applications in neuro-pharmacological studies. Moreover, it includes a concise yet comprehensive introduction to both 2D and 3D neuronal networks coupled to MEAs, and discusses the advantages, limitations and challenges of their applications as cellular and tissue-like in vitro experimental model systems.

Continuous cell lines derived from human cancers are the mostwidely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions offundamental importance to the relevanceof human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative oftumors at that site is naive and misleading."

Cell biologists have recently come to understand that asymmetry of division is an important regulatory phenomenon in the fate of a cell. In adult organisms asymmetric divisions regulate the stem cell reservoir and are a source of the drift that contributes to aging. This book describes the phenomenon in different organisms and addresses its implications for the development of the organism, cell differentiation, human aging and the biology of cancers.

In March 2000 leading scientists gathered at the Centro Seminariale Monte Verita, Ascona, Switzerland, for the Third International Symposium on "Fractals 2000 in Biology and Medicine." This interdisciplinary conference was held over a four-day period and provided stimulating contributions from the very topical field Fractals in Biology and Medicine. This Volume III in the MBI series highlights the growing power and efficacy of the fractal geometry in understanding how to analyze living phenomena and complex shapes. Many biological objects, previously considered as hopelessly far from any quantitative description, are now being investigated by means of fractal methods. Researchers currently used fractals both as theoretical tools, to shed light on living systems self-organization and evolution, and as useful techniques, capable of quantitatively analyzing physiological and pathological cell states, shapes and ultrastructures. The book should be of interest to researchers and students from Molecular and C"

The fungus fusarium is a major plant pathogen that causes disease in nearly every agriculturally important plant. In addition, some strains produce mycotoxins that can cause serious illness in humans and livestock. The enormous economic importance of and health hazards posed by fusarium have fuelled research into its biochemistry, genetics, genomics, proteomics and metabolomics by scientists worldwide. In this book, an international group of researchers critically review the most important research on the genomics and molecular and cellular biology of fusarium.

Exocytosis is a fundamental cellular process that is used by eukaryotic cells to release a variety of biological compounds including peptide hormones and neurotransmitters or to insert specific lipids and proteins in the plasma membrane. In recent years, a multidisciplinary approach promoted an extraordinary progress in the understanding of the molecular mechanisms regulating exocytosis. This led to the discovery of a large number of components belonging to the machinery that governs the fusion of secretory vesicles with plasma membranes in different cell systems, including neuronal and endocrine cells. The basic machinery required for vesicle fusion turned out to be well conserved through evolution from yeast to man. So far, because of the large number of components involved, understanding of the molecular basis of exocytosis has remained the privilege of a relatively small group of specialists. This book, written by recognized experts in the field aims at clarifying for a non-specialist audience the role of the key players in the exocytotic process not only in neuronal and endocrine cells but also in a variety of other relevant cell systems. introduce researchers and students to the forefront of this rapidly moving and fascinating field.

Haploid plants have the gametophytic number of chromosomes. They are of great importance, especially in studies on the induction of muta tions and also for the production of homozygous plants, they are needed in large numbers. The conventional methods employed by plant breeders for their production are cumbersome, time-consuming, laborious and rather inefficient. Sometimes it may take years to produce a pure line. However, with the introduction of in vitro techniques, especially anther culture for the induction of androgenesis, it has become increasingly evi dent that these methods considerably accelerate the production of haploids for plant breeding programs. During the last decade, in vitro-produced haploids have been incor porated into breeding programs of many agricultural crops, and positive results have been obtained especially with rice, wheat, potato, barley, maize, asparagus, sunflower, brassica, tobacco, etc. Among these, rice and wheat are the best examples in which a number of improved varieties have been released. In wheat, the breeding cycle can be shortened by three or four generations when the pollen haploid breeding method is used instead of conventional cross-breeding. The release of the wheat varieties Jinghua 1 and Florin is a typical example of what can be achieved with other crops. Taking these developments into considera tion, the present volume, Haploids in Crop Improvement I, was compil ed."

This essential volume explores mesenchymal stem cells (MSCs) and their potential to suppress immune-mediated inflammation. The chapters examine applications in autoimmune diseases such as lupus, rheumatoid arthritis and multiple sclerosis; blood cancers such as leukemia and lymphoma; and reproductive complications, specifically pre-term labor and use of MSCs in vitro and in animal models to discover methods of suppressing the causal inflammatory response. It also further defines the methodologies required to develop research on MSCs in vitro into established preclinical animal models including those which are proven replicas of autoimmunity and pre-term labor, to name but two. Mesenchymal Stem Cells and Immunomodulation, part of Springer's Stem Cell Biology and Regenerative Medicine, is an invaluable resource for researchers and clinicians working with stem cells, autoimmune disease, oncology, and reproductive medicine.

Ion channels are the major class of membrane proteins responsible for rapid and regulated transport of ions across biological membranes and for the generation and propagation of electrical signals in the brain, heart, and skeletal and vascular tissues. Ion channels are also known to play critical roles in regulation of cell proliferation, insulin secretion and intracellular signaling in a variety of cell types. This book focuses on the roles of ion channels in vascular tissues under normal and pathological conditions. Vascular abnormalities are known to underlie a plethora of severe pathological conditions, such as atherosclerosis, systemic and pulmonary hypertension, coronary or cerebral vasospasm, and diabetes. In addition, misregulated angiogenesis is one of the major contributors to the development of tumors. Therefore, it is clearly imperative to obtain a better understanding of the molecular mechanisms that contribute to vascular disorders. This book will be the first comprehensive assembly of assays to present the studies that have been done during the last decade to elucidate the roles of ion channels in different vascular diseases.

Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, application details for both the expert and non-expert reader, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Artificial Neural Networks: Second Edition aids scientists in continuing to study Artificial Neural Networks (ANNs).

This volume presents the most current reviews on how cancer stem cells (CSCs) hypothesis dictates that the continued proliferation of a tumor is dependent on a sub-population of self-renewing and asymmetrically dividing neoplastic stem cells that supply a largely differentiated tumor. This volume provides a comprehensive overview of the characteristics of CSCs, their role in central nervous system (CNS) tumors, and the recent CSC-specific treatment modalities being used. The emerging focus on CSCs in brain tumors represents a paradigm shift in our understanding of the pathogenesis of these neoplasms. Importantly, the realization that a distinct sub-population of cells contributes disproportionately to the growth and sustenance of central nervous system tumors has important implications for the treatment of such tumors. To treat CNS tumors, there is now a growing need to treat CSCs to achieve adequate tumor control.

Writing or editing a book on a very topical field of science is always a great challenge,since by the time the book is published some of the newest and latest findings might be obsolete compared with results reported in the most current issues of various high-level journals. Nevertheless,stimulating good books describe complicated systems and int- relationships and provide a broad spectrum of material for talented researchers who may find new inspiration from a joint presentation of correlated data. Of course,an editor cannot rank his own book. However,in this case,the contrib- ing authors have high scientific standards and well-known achievements which speak for themselves. Transmembrane signaling has many different forms and biochemical and biophysical details. However,the final outcome of transmembrane signaling at the cellular level elucidates some cellular functions, which are at the center of se- defense, alimentation, escape reactions, etc. Transmembrane signaling can be studied best in the immune system,in particular in lymphocytes,the main cel- lar carriers of immune defense. The different chapters are independent studies, written by well-known experts in their particular fields. Some chapters include the authors' very recent data, generalized, on the one hand, to provide und- standable material for those who are interested in the field but not experts. On the other hand,the current data and novel efforts to unify biochemical and bioph- ical events in a physiological description provide interesting reading for experts as well.

This thoughtful and provocative book provides a concise, up-to-date presentation of how current and projected future phosphorus scarcity will affect legume growth and their symbiotic nitrogen-fixing capabilities. It is a timely examination of the physiological and molecular responses of nodules to phosphorous deficiency in attempt to identify common principles. Students and researchers in the many disciplines related to crop productivity will find this title an exciting contribution in the area of plant stress physiology. The knowledge in this volume can also aid plant breeders, particularly through new methods of genetic engineering, in developing unique and adaptive cultivars with higher symbiotic efficiency. The awareness of the rapidly rising world population must translate into a parallel increase in agricultural production in order to sustain the growing population both now and in the future. Hence, the demand for food crops to produce proteins and vegetable oil for human consumption is going to increase considerably during the coming years. The essential role of legumes in agriculture is well-recognized, given the abundant levels of proteins and oils found in plants along with their enormous contribution to the sustainability of agricultural systems and human health. The capacity of legumes to fix nitrogen (N2) in partnership with rhizobia provides an input-saving and resource-conserving alternative, thereby reducing the need for chemical fertilizers while enhancing overall crop productivity. The use of N2-fixing legumes to produce plant proteins results in a substantial decrease in the consumption of fossil fuels and therefore also in the agricultural effects to global warming. However, a major constraint to legume production is low soil phosphorus (P) availability, considering that an overwhelming majority of the world's soils are classified as P-deficient. Low-P availability is especially problematic for legumes, since legume nodules responsible for N2 fixation have a high P requirement. Therefore, this book explains how nodule N2 fixation responds to low P availability, which is crucial for improving legume production and maintaining agricultural sustainability in the context of the global P crisis.
