Phase transitions occur throughout nature. The most familiar example is the one that occurs in water the abrupt, discontinuous transition from a liquid to a gas or a solid, induced by a subtle environmental change. Practically magical, the ever-so-slight shift of temperature or pressure can induce an astonishing transition from one entity to another entity that bears little resemblance to the first. So "convenient" a feature is seen throughout the domains of physics and chemistry, and one is therefore led to wonder whether it might also be common to biology. Indeed, many of the most fundamental cellular processes are arguably attributable to radical structural shifts triggered by subtle changes that cross a critical threshold. These processes include transport, motion, signaling, division, and other fundamental aspects of cellular function. Largely on the basis of this radical concept, a symposium was organized in Poitiers, France, to bring together people who have additional evidence for the role of phase transitions in biology, and this book is a compendium of some of the more far-reaching of those presentations, as well as several others that seemed to the editors to be compelling. The book should be suitable for anyone interested in the nature of biological function, particularly those who tire of lumbering along well trodden pathways of pursuit, and are eager to hear something fresh. The book is replete with fresh interpretations of familiar phenomena, and should serve as an excellent gateway to deeper understanding."

This volume assembles protocols for chromosome engineering and genome editing in two recently developed approaches for manipulating chromosomal and genomic DNA in plants. The first approach is a "plant chromosome vector" system, which allows the introduction of desired genes or DNA into target sites on the chromosome vector, particularly by sequence-specific recombination. The second approach is "genome-editing," which makes it possible to introduce mutations into any of the genes of DNA that we wish to change. In addition, this book also covers other related techniques used to accelerate progress in plant chromosome and genome engineering. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Chromosome and Genomic Engineering in Plants: Methods and Protocols provides a comprehensive source of protocols and other necessary information to anyone interested in this field of study.
In Neuroprotective Signal Transduction prominent researchers and clinicians focus on how inter- and intracellular signaling mechanisms prevent the degeneration and death of neurons occurring in both acute and chronic neurodegenerative disorders. Authoritative contributions dissect the signaling pathways of an array of neuroprotective factors-ranging from neurotrophins (NGF, BDNF, NT-3, and NT-4/5), to growth factors (bFGF, IGF-1, GDNF), to cytokines (TNF, IL-1b, and TGFb), to secreted amyloid precursor proteins, to protease nexin-1. Also treated are cytoprotective signaling events that occur within injured neurons independently of intercellular signals. Neuroprotective Signal Transduction presents fundamental, cutting-edge treatment of the cellular and molecular signal transduction pathways found in human neurodegenerative conditions. The book's elucidation of the molecular cascades evolved by the nervous system to protect itself is now lead to effective strategies for preventing neuronal degeneration in such conditions as stroke, traumatic brain injury, Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis, and will form the basis for powerful new drug discovery and gene therapy strategies.
When first conceived, not only was the aim of Protocols for Oligo nucleotides and Analogs to provide wide coverage of the ohgonuc- otide chemistry field for readers who are well versed within the field, but also to give investigators just entering into the field a new perspective. The very first book on this topic was edited and published by Michael Gait in 1984, in whose laboratory I encountered the newer aspects of oligonucleotide chemistry. Since then, oligonucleotide research has developed to such an extent that its uses extend far beyond basic studies, and now find wide application throughout clinical science as well. Until recently, the major application of oligonucleotides has been in the area of DNA-based diagnostic and "antisense oligonucleotid- based therapeutic approaches. However, oligonucleotides are now also being used as therapeutic agents and are thus frequently found in clinical trials in humans. Synthesis of unmodified oligonucleotides using automated synthe sizers has become a common practice in numerous laboratories. How ever, improvements on the existing techniques and the introduction of ever newer methods for oligonucleotide synthesis is constantly driving ahead in the leading research laboratories. And several new oligonucle otide analogs have been synthesized and studied for their individual prop erties in recent years. The present volume strives to bring the readers the most up-to-date information on the newest aspects of synthesis of oligo nucleotides and their analogs. A separate volume covers synthesis of oligonucleotide conjugates, along with most of the analytical techniques presently used for analysis of oligonucleotides."
In the summer of 1988, my developmental biology professor announced to the class that hematopoietic stem cells (HSCs) had finally been purified. Somehow, I never forgot the professor's words. When I started working in Dr. Irv Weissman's labo- tory at Stanford as a postdoctoral fellow, I realized that the findings mentioned by the professor were from Weissman's laboratory and had been published in a 1988 edition of the journal Science. It has been over 20 years since the publication of that seminal paper, and since then tremendous advances in understanding the biology and maturation of HSCs, namely the process of hematopoiesis, which includes lymphocyte development, have been made. These discoveries were made possible in part by advancements in technology. For example, recent availability of user friendly fluorescence activated cell sorting (FACS) machines and monoclonal an- bodies with a variety of fluorescent labels has allowed more scientists to sort and analyze rare populations in the bone marrow, such as HSCs. All classes of hematopoietic cells are derived from HSCs. Stem cell biology draws enormous attention not only from scientists, but also from ordinary people because of the tremendous potential for development of new therapeutic application to diseases that currently lack any type of effective therapy. Thus, this type of "regenerative medicine" is a relatively new and attractive field in both basic science and clinical medicine.
The Chlamydomonas Sourcebook, Third Edition, Volume Three: Cell Motility and Behavior has been fully revised and updated to include the wealth of new resources for the Chlamydomonas community. The book presents the latest advances in the area from an international array of expert authors, reflecting significant advancements in our understanding of the role of basal bodies and flagella in human diseases. In addition, employing quantitative proteomics/mass spectroscopy as well as cryo EM tomography and single particle cryo EM has revolutionized our knowledge of the axoneme in terms of the location of proteins and their interactions. Current insights on mitosis and cytokinesis, flagellar assembly and motility, intraflagellar transport, and more will ensure use of this reference as a guide for understanding human diseases of the cilium.

The beta cells of the pancreatic islets of Langerhans are the only cells in the body that produce and secrete insulin. This metabolic hormone plays a central role in the maintenance of glucose homeostasis. This book provides a comprehensive review of the beta cell in health and disease. The book s primary aim is to encourage investigators to become actively involved in diabetes research and the search for new approaches to prevent and treat diabetes.
Communication between cells via intercellular channels gap junctions appears essential to certain developmental processes and appropriate organ function. Gap Junctions in Development and Disease aims to describe the molecular events underlying impaired development and disease. Beginning with a comprehensive review of various mouse and human genes encoding the channel-forming connexins, later chapters describe several connexin mutations associated with human diseases such as hereditary deafness and female infertility. Erroneous signaling mediated by the interaction of mutant connexins with other proteins, thought to be responsible for dysfunction of organs such as heart, muscle, brain, skin, lens, placenta, and endocrine tissue in both mice and men, is also addressed. Although the question of why some mutations in gap-junction proteins lead to specific phenotypes remains to be answered, the reviews in this book provide an intriguing insight into the future direction of this research field."
This book is the lasting product, a resource of up-to-date information in the scientific literature for the field of animal cell technology, as it was presented during a pleasant and stimulating meeting in TylAsand, Sweden, in June 2001. The title of the meeting, From Target to Market, indicates the usefulness of Animal Cell Technology during all steps in the pharmaceutical development process. Following the biotech products reaching the market, it shows an upward trend in the contribution of biotech products to total New Molecular Entity output in the nineties, which continued until 1996 when biotech represented 25% of the annual output. Since then the proportion has been decreasing. A perceived hurdle from a market perspective is that a protein per definition is biodegradable and thus requires intravenous, or for some drugs subcutaneous administration. New promising administration technologies such as pulmonary delivery were highlighted at this meeting. The emphasis on project selection prior to entry in the development phase has triggered a portfolio management using more extensive preclinical data before a development decision is taken. Animal cells have become a very important tool in the drug discovery process. The next generation of products will evolve from applications such as gene therapy, novel vaccines, cell therapy, and gene regulation. Animal cell technology has a major role to play in the post-sequence era.
By the end of the 1980s only two microtubule-dependent motors, the plus end-directed kinesin and the minus end-directed cytoplasmic dynein, had been identified. At the time, these two motors seemed almost sufficient to explain directional motility events on polar microtubule tracks in the cell. No- theless, shortly after, the tip of the iceberg began to emerge with the identi- cation of proteins containing in their sequences a domain found in kinesin. This domain, called the "motor domain," conferred on these proteins the essential property of moving on microtubules, using the energy derived from ATP hydro- sis. Since then, the identification of new proteins belonging to the kinesin superfamily of microtubule-dependent motors has gone at such a pace that nowadays more than 200 entries with motor domain sequences are deposited in the database. Kinesin family members are found in all eukaryotic org- isms tested. They present a wide range of domain organizations with a motor domain located at different positions in the molecule. Their motility prop- ties are also variable in directionality, velocity, and such other characteristics as bundling activity and processivity. Finally, and most important, they p- ticipate in a multitude of cellular functions. Our understanding of many cel- lar events, such as mitotic spindle assembly and neuronal transport, to cite only two, has progressed substantially in the last few years thanks to the id- tification of these motors.
Covering 100 years of zoological research, the Handbook of Zoology represents a vast store of knowledge. Handbook of Zoology provides an in-depth treatment of the entire animal kingdom covering both invertebrates and vertebrates. It publishes comprehensive overviews on animal systematics and morphology and covers extensively further aspects like physiology, behavior, ecology and applied zoological research. Although our knowledge regarding many taxonomic groups has grown enormously over the last decades, it is still the objective of the Handbook of Zoology to be comprehensive in the sense that text and references together provide a solid basis for further research. Editors and authors seek a balance between describing species richness and diversity, explaining the importance of certain groups in a phylogenetic context and presenting a review of available knowledge and up-to-date references. New contributions to the series present the combined effort of an international team of editors and authors, entirely published in English and tailored to the needs of the international scientific community. Upcoming volumes and projects in progress include volumes on Annelida (Volumes 1-3), Bryozoa, Mammalia, Miscellaneous Invertebrates, Nannomecoptera, Neomecoptera and Strepsiptera and are followed later by fishes, reptiles and further volumes on mammals. Background The renowned German reference work Handbook of Zoology was founded in the 1920's by Professor Willi Kukenthal in Berlin and treated the complete animal kingdom from single cell organisms to mammals in eight thematic volumes: Volume I Protozoa, Porifera, Colenteratea, Mesozoa (1925); Volume II Vermes (1933/34); Volume III Arthropoda ex. Insecta (1927/1932); Volume IV Arthropoda: Insecta; Volume V Solenogastres, Mollusca, Echinoderma (1925); Volume VI Pisces / Amphibia (1930); Volume VII Reptilia / Aves (1931); Volume VIII Mammalia. The Volumes IV Arthropoda: Insecta and VII Mammalia continued publication into the present with the most recent contributions in English language. Adapting to the accelerating speed of scientific discovery in the past decades the Handbook of Zoology entered a next phase in 2010. In the new edition of the Handbook of Zoology, the original eight thematic volumes gave way for smaller and more flexible groupings that reflect the current state of phylogenetic knowledge. All subsequent volumes were published in print as well as e-book format. The Handbook of Zoology is additionally offered as a database, the Handbook of Zoology Online, which can easily be searched and rapidly updated. Original Handbook material (ca. 28 000 pages) has been reordered along taxonomic (instead of bibliographical) categories and forms the historical basis of this Online Reference Work. As a living Online Reference, the content is continuously updated and new content added. The material can be accessed through taxonomic and subject categories as well as free text, with a diversity of linking and search options. Faster publication times through online-first publication, reference- and cross-linking, and make the Handbook of Zoology highly attractive to both authors and users.

This book critically evaluates the causal link between cell division machinery and disease. Further, it identifies key open questions in the field and the means for exploring them. Throughout the various chapters, internationally known contributors present the evidence for and against a causal link between key elements of the cell division machinery and diseases such as cancer, neuropathologies, aging, and infertility. A more clinically oriented chapter further discusses the current and future applications of anti-mitotic drugs in these diseases. Cell Division Machinery and Disease is essential reading for graduate or advanced graduate students, researchers or scientists working on cell division as well as clinicians interested in the molecular mechanisms of the discussed diseases.
Cell senescence is the process whereby cells permanently lose the possibility to proliferate without undergoing cell death, and occurs in a plethora of distinct model organisms. In Cell Senescence: Methods and Protocols, expert researchers in the field detail the methods that are now commonly used to study cell senescence, in model organisms encompassing bacteria, fungi, worms, flies, zebrafish, and mammalian cells. These techniques cover the study of all the morphological, biochemical and functional manifestations of senescence at the cellular level and include protocols for population analyses and high-throughput approaches in suitable model organisms. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls.

This book presents an overview of the current state of research on ultrashort electric field pulses of high intensity and their use in biology and medicine. It examines in detail the most recent and exciting advances in how nanosecond and picosecond electric pulse research has grown and expanded into new areas of biology and medicine. Further, the book specifically focuses on electric pulses in the time domain, on intracellular effects as opposed to plasma membrane electroporation, and highlights the biological and medical applications of these unique pulse effects. Since the authors were initial innovators exploring nanosecond and picosecond pulses, their unique perspectives foreshadowed directions the research took, expanding into new areas that they continue to investigate today.
In the last ten years there has been a considerable increase of interest on the notion of the minimal cell. With this term we usually mean a cell-like structure containing the minimal and sufficient number of components to be defined as alive, or at least capable of displaying some of the fundamental functions of a living cell. In fact, when we look at extant living cells we realize that thousands of molecules are organized spatially and functionally in order to realize what we call cellular life. This fact elicits the question whether such huge complexity is a necessary condition for life, or a simpler molecular system can also be defined as alive. Obviously, the concept of minimal cell encompasses entire families of cells, from totally synthetic cells, to semi-synthetic ones, to primitive cell models, to simple biomimetic cellular systems. Typically, in the experimental approach to the construction of minimal the main ingredient is the compartment, lipid vesicles (liposomes) are used to host simple and complex molecular transformations, from single or multiple enzymic reactions, to polymerase chain reactions, to gene expression. Today this research is seen as part of the broader scenario of synthetic biology but it is rooted in origins of life studies, because the construction of a minimal cell might provide biophysical insights into the origins of primitive cells, and the emergence of life on earth. The volume provides an overview of physical, biochemical and functional studies on minimal cells, with emphasis to experimental approaches. 15 International experts report on their innovative contributions to the construction of minimal cells. |
