The research field of biobanks and tissue research is highly promising. Many projects around the globe are involved in the collection of human tissue and health data for research purposes. These initiatives are driven by the perspective of decisive breakthroughs in the knowledge of the genetic pathways involved in widespread diseases. However, there are considerable ethical and legal challenges to be considered as well. These challenges encompass the use of body material for research purposes, the misuse of genetic and other health data by third parties, trust in science and medicine, concerns regarding privacy, use of genetic data for forensic applications by the state and the police, and regulatory issues. This volume is divided into three parts: the inclusion of the public, the rights of donors and patients, examples and recommendations for the future of tissue research. It presents a comprehensive overview of the most important topics in the field by renowned scholars in medical ethics and biolaw.

Mitochondria in plants, as in other eukaryotes, play an essential role in the cell as the major producers of ATP via oxidative phosphorylation. However, mitochondria also play crucial roles in many other aspects of plant development and performance, and possess an array of unique properties which allow them to interact with the specialized features of plant cell metabolism. The two main themes running through the book are the interconnection between gene regulation and protein function, and the integration of mitochondria with other components of plant cells. The book begins with an overview of the dynamics of mitochondrial structure, morphology and inheritance. It then discusses the biogenesis of mitochondria, the regulation of gene expression, the mitochondrial genome and its interaction with the nucleus, and the targeting of proteins to the organelle. This is followed by a discussion of the contributions that mutations, involving mitochondrial proteins, have made to our understanding of the way the organelle interacts with the rest of the plant cell, and the new field of proteomics and the discovery of new functions. Also covered are the pathways of electron transport, with special attention to the non-phosphorylating bypasses, metabolite transport, and specialized mitochondrial metabolism. In the end, the impact of oxidative stress on mitochondria and the defense mechanisms, that are employed to allow survival, are discussed. This book is for the use of advanced undergraduates, graduates, postgraduates, and beginning researchers in the areas of molecular and cellular biology, integrative biology, biochemistry, bioenergetics, proteomics and plant and agricultural sciences.
Cell cycle checkpoints control the fidelity and orderly progression of eukaryotic cell division. By controlling the orderly progression of critical cell cycle events such as DNA replication and chromosome segregation and ensuring proper repair of damaged DNA, cell cycle checkpoints function to ensure genome integrity. Mechanisms of checkpoint controls are not only the research focus of investigators interested in mechanisms that regulate the cell cycle, but are also the interests of researchers studying cancer development as it is increasingly clear that loss of cell cycle checkpoints, which leads to genomic instability as a result, is a hallmark of tumorigenesis. Cell Cycle Checkpoints: Methods and Protocols provides detailed descriptions of methodologies currently employed by researchers in the field, including those commonly used in the mammalian, yeast, C. elegans, Drosophila, and Xenopus model systems. Each chapter describes a specific technique or protocol, such as a method to induce cell cycle checkpoints in a particular model system, to synchronize a population of cells to allow observations of cell cycle progression, to identify genes involved in checkpoint regulation, and to study particular protein components of cell cycle checkpoint pathways. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Cell Cycle Checkpoints: Methods and Protocols seeks to serve both professionals and novices with its well-honed methodologies in an effort to further our knowledge of this essential field.
Disulfide-containing proteins belong to a unique class of proteins for studying the mechanism of protein folding. Their folding mechanism can be analyzed by three distinct techniques: (1) The conventional denaturation-renaturation method (disulfide intact); (2) The disulfide oxidation method (oxidative folding); and (3) The emerging disulfide scrambling method. Each technique provides specific information as to how an unfolded disulfide protein refolds to form the native structure. This book is intended to highlight the knowledge of several important proteins (BPTI, RNase A, beta-Lactalbumin and Lysozyme etc.) that have been characterized in depth by these methodologies. The book will also devote sections to comparing these methodologies and chaperones (PDI and Dsb machineries) that facilitate folding of disulfide proteins. Folding of Disulfide Proteins aims to cover the knowledge of protein folding accumulated from studies of disulfide-containing proteins, including methodologies, folding pathways, and folding mechanism of numerous extensively characterized disulfide proteins. This book will be of interest to those interested in problems related to protein folding, and anyone who is interested in understanding the mechanism of protein misfolding and protein misfolding-related diseases. Folding of Disulfide Proteins aims to cover the knowledge of protein folding accumulated from studies of disulfide-containing proteins, including methodologies, folding pathways, and folding mechanism of numerous extensively characterized disulfide proteins.

This book puts the ethics, policy and politics of stem cells into context in a way that helps readers understand why past and current issues have developed the way they have and what the implications are for their work going forward. It also addresses emerging issues as the field progresses towards clinical and industrial uses. While there is a superabundance of material on the ethics of embryo use and questions of embryonic "personhood," there is little that covers what practicing scientists and managers need to know in order to plan and execute responsible research. Furthermore, researchers funded by the NIH are required to have ethics training as a condition of the grant. As such, this book is an essential resource to all of these pre-professional students whether they plan to move into industry, government or academia.
Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II reducing chromosome number from the diploid level to a haploid genome and recombining chromosome arms by crossing-over. In animals, all this happens during formation of eggs and sperm in yeasts before spore formation. The mechanisms of reciprocal exchange at crossover/chiasma sites are central to mainstream meiosis. To initiate the meiotic exchange of DNA, surgical cuts are made as a form of calculated damage that subsequently is repaired by homologous recombination. These key events are accompanied by ancillary provisions at the level of chromatin organization, sister chromatid cohesion and differential centromere connectivity. Great progress has been made in recent years in our understanding of these mechanisms. Questions still open primarily concern the placement of and mutual coordination between neighboring crossover events. Of overlapping significance, this book features two comprehensive treatises of enzymes involved in meiotic recombination, as well as the historical conceptualization of meiotic phenomena from genetical experiments. More specifically, these mechanisms are addressed in yeasts as unicellular model eukaryotes. Furthermore, evolutionary subjects related to meiosis are treated."

Simple carbohydrates, complex oligosaccharides and polysaccharides all belong to a class of ubiquitous (macro)molecules that exhibit a wide range of biological functions, and the recent advent of enhanced enzymatic, chemical and analytical tools used to study these sugars has inaugurated a genuine explosion in the field of glycomics. Specifically, it has led to a deeper understanding of how specific sugar structures modulate cellular phenotypes, and that breakthrough has led to the discovery of new pharmaceuticals for the treatment of many serious diseases, such as cancer. The subsequent rapid expansion of this research holds high promise for future therapeutic regimens, and capillary electrophoresis (CE) refers to the range of related separation techniques that are integral to this vital research. CE uses narrow-bore fused-silica capillaries to separate a complex array of large and small molecules, and Capillary Electrophoresis of Carbohydrates offers a comprehensive look at the latest breakthroughs and improvements in CE and CE techniques applied to monosaccharides up to complex oligosaccharides and polysaccharides. It begins with an overview of the application of CE and CE- mass spectrometric in the analysis of simple carbohydrates without any previous derivatization step before discussing various detection techniques such as spectrophotometric detection, electrochemical detection and other less common techniques. It then covers in detail an array of related topics and numerous applications. It is an essential text for anyone exploring the myriad possibilities of this rapidly expanding field.

Enzymes and whole cells are able to catalyze the most complex chemical processes under the most benign experimental and environmental conditions. In this way, enzymes and cells could be excellent catalysts for a much more sustainable chemical industry. However, enzymes and cells also have some limitations for nonbiological applications: fine chemistry, food chemistry, analysis, therapeutics, and so on. Enzymes and cells may be unstable, difficult to handle under nonconventional conditions, poorly selective toward synthetic substrates, and so forth. From this point of view, the transformation-from the laboratory to industry-of chemical processes catalyzed by enzymes and cells may be one of the most complex and exciting goals in biotechnology. For many industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used over very long periods of time. From this point of view, immobilization, simplicity, and stabilization have to be strongly related concepts. Over the last 30 years, a number of protocols for the immobilization of cells and enzymes have been reported in scientific literature. However, only very few protocols are simple and useful enough to greatly improve the functional properties of enzymes and cells, activity, stability, selectivity, and related properties.

Many plants produce enzymes collectively known as ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of an adenine residue from a conserved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors. Ribosomes modified in this way are no longer able to carry out protein synthesis. Most RIPs exist as single polypeptides (Type 1 RIPs) which are largely non-toxic to mammalian cells because they are unable to enter them and thus cannot reach their ribosomal substrate. In some instances, however, the RIP forms part of a heterodimer where its partner polypeptide is a lectin (Type 2 RIPs). These heterodimeric RIPs are able to bind to and enter mammalian cells. Their ability to reach and modify ribosomes in target cells means these proteins are some of the most potently cytotoxic poisons found in nature, and are widely assumed to play a protective role as part of the host plant's defenses. RIPs are able to further damage target cells by inducing apoptosis. In addition, certain plants produce lectins lacking an RIP component but which are also cytotoxic. This book focuses on the structure/function and some potential applications of these toxic plant proteins.

In this state-of-the-art exploration of a hugely dynamic and fast-evolving field of research, leading researchers share their collective wisdom on the role that stem cells could play in the context of physiological stress and lung injury. The text focuses on reviewing the most relevant-and recent-ideas on using local, endogenous, and exogenous progenitor/stem cells in preventing and treating injury to the lung. The lungs are one of the most complex organs in the human body, with a mature adult lung boasting at least 40 morphologically differentiated cell lineages. Our entire blood supply passes through the lung's alveolar units during oxygenation. This interaction with the outside world, along with the intricacies of its structure, makes the lung a highly susceptible organ that is vulnerable to numerous types of injury and infection. This means that the mechanisms of lung repair are in themselves correspondingly complex. Because of their multipotentiality, as well as the fact of the lung's relatively rapid cell turnover, stem cells are thought to be an important alternative cell-base therapy in lung injury. Despite the controversial nature of stem cell research, there has been growing interest in both local and endogenous stem cells in the lung. This highly topical book with chapters on everything from using mesenchymal stem cells in lung repair to the effect of physical activity on the mobilization of stem and progenitor cells, represents an exciting body of work by outstanding investigators and will be required reading for those with an interest in the subject.

of diseases such as heart disease, allergy, asthma, and cancer. As
a result of the discovery of this link to disease, the topic of
chemokines and drugs that block their actions has become an intense
are of study. This book presents the topics of chemokines,
chemokine receptors, and related pathologies in an integrated
manner that provides the reader with a comprehensive and up-to-date
knowledge of these topics.
Biomaterials for Surgical Operation offers a review of the latest advances made in developing bioabsorbable devices for surgical operations which include surgical adhesives (sealants), barriers for the prevention of tissue adhesion, polymers for fractured bone fixation, growth factors for the promotion of wound healing, and sutures. Over the years, many descriptions of biomaterials have appeared in academic journals and books, but most of them have been devoted to limited clinical areas. This is in marked contrast with this volume which covers a wide range of bioabsorbable devices used in surgery from a practical point of view. The currently applied polymeric devices are critical in surgery, but all involve serious problems due to their poor performance. For instance, fibrin glue, the most widely used surgical sealant, can produce only a weak gel with low adhesive strength to tissues, accentuating the limited effectiveness of current treatment options. Likewise, the currently available barrier membranes cannot fully prevent tissue adhesion at the acceptable level and are, moreover, not easy to handle with endoscopes due to their poor mechanical properties. Biomaterials for Surgical Operation is aimed at those who are interested in expanding their knowledge of how the problems associated with the currently used devices for surgical operation can be solved. It primarily focuses on the absorbable biomaterials which are the main components of these medical devices.
Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants' responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

"About 25 years ago, Mosmann & Coffman introduced the TH1 / TH2 paradigm of T helper cell differentiation which helped explain many aspects of adaptive immunity from eliminating intracellular versus extracellular pathogens to induction of different types of tissue inflammation. However, TH1 / TH2 paradigm could not adequately explain development of certain inflammatory responses which provided impetus for the discovery of a new subset of T cells called TH17 cells. After the discovery of differentiation and transcription factors for TH17 cells, it was clear that TH17 cells represent an independent subset of T cells with specific functions in eliminating certain extracellular pathogens, presumably not adequately handled by TH1 or TH2 cells. The major role of TH17 cells has been described in inducing auto-immune tissue inflammation. The discovery of TH17 cells has expanded the TH1 / TH2 paradigm, and the integration of TH17 cells with TH1 and TH2 effector T cells is beginning to explain the underlying mechanisms of tissue inflammation in a number of infections and auto-immune disease settings." - From Chapter One by Vijay K. Kuchroo, Harvard University, USA "The recently identified Interleukin 17 (IL-17) cytokine family contributes to immunity to infectious diseases and chronic inflammatory diseases. Further studies on the regulation and function of this important cytokine family may provide better understanding on the roles of the IL-17 family in immune-mediated diseases; such knowledge may lead to the development of immunotherapeutic strategies for treatment of several inflammatory diseases." - From Chapter Two by Chen Dong, University of Texas and MD Anderson Cancer Center, USA
This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other "methanogenic" mammals contribute significantly to the global methane budget; especially the rumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology. |
