Inside this book are reflections on the nature of vision and blindness. Further, there are explorations of interpretive research, and presentations of some seminal and contemporary publications in the field of blindness. The other major fodder for conversation with you the reader is an elaborated example of empirical research entitled Blind Online Learners. Each element of this inquiry is explicitly reflected upon as an example of interpretive research. This book is intended for four intersecting groups of readers. If you are a philosopher, closet or sanctioned, then you cannot ponder the nature of being without due consideration for vision, and cannot contemplate the role of seeing in our lives without listening to the stories of those who are blind. The tales within this text are particularly contemporaneous because they are contextualized by the cyber-phenomena of online learning. This segues to the second group of readers, as the described empirical research was originally intended to bring greater depth and breadth of understanding to the field of educational technology, particularly as it intersects with disability studies. There is a paucity of published literature that has inquired into disabled online learners, and this research study responds to that call. Third, this book may be used as a textbook on approaches to interpretive empirical research. It is as close as one may come to a recipe, walking students through a specific example. Because it is situated in actual empirical research, the intention was that it avoid the trap of being prescriptive or formulaic. Finally, the text is intended for readers interested in the field of blindness. The text reviews some of the seminal and contemporary research on blindness, and then presents an elaborated example of what we can and should expect to emerge in the knowledge production industry, changing what it means to be blind.

This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences.Understanding reproductive biology is centrally important to the way many of the world's conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world's fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 - 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.

Humans have utilized the bioactive principles of different plants for various beneficial physiological properties including antimicrobial properties for many centuries. However, interests of using medicinal plants declined in the 20th century with the availability of effective synthetic antimicrobial drugs. The development of microbial resistance to various drugs has accelerated research interests towards the use of phytochemicals as alternatives to synthetic drugs in the recent years. This book presents an comprehensive reviews on the antimicrobial and antiviral properties of numerous recently reported phytochemicals, and their mechanisms of antimicrobial actions. Some of the chapters have critically discussed the beneficial and adverse effects of antibacterial, and stimulatory activities of dietary phytochemicals on rumen microbial populations, and gut microbial populations of humans and animals. Microbial adaptation and resistance of microbes to phytochemicals has also been highlighted. On the applied apects, the use of phytochemicals against drug resistance microbes, to treat microbial diseases, for food preservation, to inhibit methanogenic archaea in the rumen, and to modulate lipid biohydrogenating microbial populations to increase conjugated linoleic acids in animal-derived foods have been presented in different chapters.

Neuropsychiatric disorders such as schizophrenia, mood disorders, Alzheimer s disease, epilepsy, alcoholism, substance abuse and others are one of the most debilitating illnesses worldwide characterizing by the complexity of the causes, and lacking the laboratory tests that may promote diagnostic and prognostic procedures. Recent advances in neuroscience, genomic, genetic, proteomic and metabolomic knowledge and technologies have opened the way to searching biomarkers and endophenotypes, which may offer powerful and exciting opportunity to understand the etiology and the underlying pathophysiological mechanisms of neuropsychiatric disorders. The challenge now is to translate these advances into meaningful diagnostic and therapeutic advances. This book offers a broad synthesis of the current knowledge about diverse topics of the biomarker and endophenotype strategies in neuropsychiatry. The book is organized into four interconnected volumes: Neuropsychological Endophenotypes and Biomarkers (with overview of methodological issues of the biomarker and endophenotype approaches in neuropsychiatry and some technological advances), Neuroanatomical and Neuroimaging Endophenotypes and Biomarkers, Metabolic and Peripheral Biomarkers and Molecular Genetic and Genomic Markers . The contributors are internationally and nationally recognized researchers and experts from 16 countries. This four-volume handbook is intended for a broad spectrum of readers including neuroscientists, psychiatrists, neurologists, endocrinologists, pharmacologists, clinical psychologists, general practitioners, geriatricians, health care providers in the field of neurology and mental health interested in trends that have crystallized in the last decade, and trends that can be expected to further evolve in the coming years. It is hoped that this book will also be a useful resource for the teaching of psychiatry, neurology, psychology and mental health. "

Despite a half century of structural, biophysical and biochemical investigations of ribonucleic acids, they are still mysterious. RNAs stand at fertile crossroads of disciplines, integrating concepts from genomics, proteomics, dynamics as well as biochemistry and molecular biology. From 20 years it is clear, that genetic regulation of eukaryotic organisms has been misunderstood for the last years that the expression of genetic information is effected only by proteins. Basic understanding of nucleic acids has enhanced our foundation to probe novel biological functions. This is especially evident for RNA molecules whose functionality, maturation, and regulation require formation of correct secondary structure through encoded base-pairing interactions.

Beginning with the Escherichia coli co protein, or bacterial DNA topoisomerase I, an ever-increasing number of enzymes has been identified that catalyze changes in the linkage of DNA strands. DNA topoisomerases are ubiquitous in nature and have been shown to play critical roles in most p- cesses involving DNA, including DNA replication, transcription, and rec- bination. These enzymes further constitute the cellular targets of a number of clinically important antibacterial and anticancer agents. Thus, further studies of DNA topology and DNA topoisomerases are critical to advance our und- standing of the basic biological processes required for cell cycle progression, cell division, genomic stability, and development. In addition, these studies will continue to provide critical insights into the cytofoxic action of drugs that target DNA topoisomerases. Such mechanistic studies have already played an important role in the development and clinical application of antimicrobial and chemotherapeutic agents. The two volumes of DNA Topoisomerase Protocols are designed to help new and established researchers investigate all aspects of DNA topology and the function of these enzymes. The chapters are written by prominent investigators in the field and provide detailed background information and st- by-step experimental protocols. The topics covered in Volume I; DNA Topology and Enzymes, range from detailed methods to analyze various aspects of DNA structure, from linking number, knotting/unknotting, site-specific recombi- tion, and decatenation to the overexpression and purification of bacterial and eukaryotic DNA topoisomerases from a variety of cell systems and tissues.

about the involvement of signaling Transforming growth factor in tumor development and metastasis. plays a central role in the signaling network that controls morphogenesis, 2. THE BASICS OF growth and cell differentiation in SIGNALING multicellular organisms. The different members of this pleiotropic family of 2. 1. receptor signaling growth and differentiation factors seem to The family of growth factors regulate many processes in human disease consists of more than thirty members in and, in particular, tumor development. humans alone (15, 16). They cluster in Our understanding of how two major groups, the group composed of initiated signals are mediated has both the bone morphogenetic proteins increased dramatically in the last fifteen (BMP) and growth and differentiation years. Firstly, the prototype of factors (GDFs), and the group formed by this still constantly growing family, was the Activins, and Nodals. The two identified and cloned (1). Secondly, the groups differ in their use of receptors for family receptors were transmembrane receptors and the identified by expression cloning from subsequent activation of the mammalian tissue culture (2-7). Thirdly, transcriptional mediators (for recent genetic screens in Drosophila reviews see (13, 14, 17)).

Phosphoinositides (PIs) are minor components of cellular membranes that play critical regulatory roles in several intracellular functions. This book describes the main enzymes regulating the turnover of each of the seven PIs in mammalian cells, some of their intracellular functions and some evidence of their involvement in human diseases. Due to the complex inter-relation between the distinct PIs and the plethora of functions that they can regulate inside a cell, this book is not meant to be a comprehensive coverage of all aspects of PIs signalling but rather an overview on the current state of the field and where it could go from here. Phosphoinositide and inositol phosphates interact with and modulate the recruitment and activation of key regulatory proteins and in doing so control diverse functions including cell growth and proliferation, apoptosis, cytoskeletal dynamics, insulin action, vesicle trafficking and nuclear function. Initially, inositide signaling was limited to the PLC pathway; however, it is now clear that all the seven phosphoinositides and more than 30 different inositol phosphates likely have specific signaling functions. Moreover there is a growing list of proteins that are regulated by inositol signaling. This has raised the question as to how inositol signaling can control diverse processes and yet maintain signaling specificity. Controlling the levels of inositol signaling molecules and their subcellular compartmentalisation is likely to be critical. This meeting will bring together scientists from different backgrounds to discuss how understanding inositol signaling may be used to target complex human diseases that manifest themselves when inositol signaling is deregulated.

For two decades, Understanding Clinical Papers has been helping students and professionals understand the research that supports evidence-based practice. Now in its fourth edition, this popular introductory textbook covers every major aspect of reading and evaluating clinical research literature, from identifying the aims and objectives of a paper to analysing the data with different multivariable methods. Numerous excerpts from actual clinical research papers make learning real and immediate, supported by a unique visual approach that reinforces key points and connects examples with the chapter material. The fourth edition includes extensively revised content throughout, including four brand-new chapters covering qualitative studies, Poisson regression, studies of complex interventions, and research using previously collected data. New and updated material discusses the difference between clinical and statistical significance, the consequences of multiple testing and methods of correction, how topic guides are used to explore and explain participants' experiences, standardised guidelines for writing trials and reviews, and much more. Offering clear explanations of important research-related topics, this reader-friendly resource: Offers a clear, concise, and accessible approach to learning how to read and analyse clinical research literature Features new coverage of qualitative research, including descriptive studies, sampling and populations, and identifying, summarising, and measuring qualitative characteristics Provides new material on missing data, sub-group analysis, feasibility and pilot studies, cluster randomised trials, and adaptive trial designs Includes new tables, abstracts, and excerpts from recent clinical research literature Understanding Clinical Papers is essential reading for all healthcare professionals and students, particularly those involved in clinical work and medical research, as well as general readers wanting to improve their understanding of research literature.

Cardiorespiratory function is prominently affected by oxidative stress. Cigarette smoking is the archetype of oxidative and nitrative stress and free radical formation. New adverse effects of smoking keep on propping up in research. The chapters provide the comprehensive view of new developments in this area regarding cardiovascular and lung function and muscle catabolism. Alterations in inflammatory cytokines and proteins as well as degradation of muscle proteins due to smoking, by far unrecognized, caused by oxidative stress also are presented. Much less is known about the effect of cognitive stress on vagally-mediated cardiorespiratory function and surprisingly, on vagal immune pathway. The experimental studies also show that clinically important meconium aspiration syndrome contains an oxidative trait which is amenable to antioxidative treatment. This volume creates a source of information on the damaging role of oxidative stress in cardiorespiratory function that has by far not been available.

Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Machine learning is a novel discipline concerned with the analysis of large and multiple variables data. It involves computationally intensive methods, like factor analysis, cluster analysis, and discriminant analysis. It is currently mainly the domain of computer scientists, and is already commonly used in social sciences, marketing research, operational research and applied sciences. It is virtually unused in clinical research. This is probably due to the traditional belief of clinicians in clinical trials where multiple variables are equally balanced by the randomization process and are not further taken into account. In contrast, modern computer data files often involve hundreds of variables like genes and other laboratory values, and computationally intensive methods are required. This book was written as a hand-hold presentation accessible to clinicians, and as a must-read publication for those new to the methods.

Animal cells are the preferred "cell factories" for the production of complex molecules and antibodies for use as prophylactics, therapeutics or diagnostics. Animal cells are required for the correct post-translational processing (including glycosylation) of biopharmaceutical protein products. They are used for the production of viral vectors for gene therapy. Major targets for this therapy include cancer, HIV, arthritis, cardiovascular and CNS diseases and cystic fibrosis. Animal cells are used as in vitro substrates in pharmacological and toxicological studies. This book is designed to serve as a comprehensive review of animal cell culture, covering the current status of both research and applications. For the student or R&D scientist or new researcher the protocols are central to the performance of cell culture work, yet a broad understanding is essential for translation of laboratory findings into the industrial production. Within the broad scope of the book, each topic is reviewed authoritatively by experts in the field to produce state-of-the-art collection of current research. A major reference volume on cell culture research and how it impacts on production of biopharmaceutical proteins worldwide, the book is essential reading for everyone working in cell culture and is a recommended volume for all biotechnology libraries.

Cancer is one of the leading killers in the world and the incidence is increasing, but most cancer patients and cancer survivors suffer much from the disease and its conventional treatments' side effects. In the past, clinical data showed that some complementary and alternative medicine (CAM) possessed anticancer abilities, but some clinicians and scientists have queried about the scientific validity of CAM due to the lack of scientific evidence. There is great demand in the knowledge gap to explore the scientific and evidence-based knowledge of CAM in the anticancer field. With this aim, a book series is needed to structurally deliver the knowledge to readers. Recently there have been encouraging results from both laboratory experiments and clinical trials demonstrating the anticancer effects of herbal medicine. There is considerable interest among oncologists and cancer researchers to find anticancer agents in herbal medicine. This volume is a specialised book presenting the up-to-date scientific evidence for anticancer herbal medicine. This unique book provides an overview of the anticancer herbal medicines and remedies, as well as a detailed evidence-based evaluation of 18 common anticancer herbal medicines covering their biological and pharmacological properties, efficacies, herb-drug interactions, adverse effects, pre-clinical studies, and clinical applications. Gathering international opinion leaders' views, this volume will contribute great to the cancer, academic, and clinical community by providing evidence-based information on the anticancer efficacy of herbal medicine. Readership Oncologists, cancer researchers, pharmacologists, pharmaceutical specialists, Chinese medicine practitioners, medical educators, postgraduates and advanced undergraduates in biomedical disciplines, cancer caregivers, cancer patients.

This book is targeted to biologists with limited statistical background and to statisticians and computer scientists interested in being effective collaborators on multi-disciplinary DNA microarray projects. State-of-the-art analysis methods are presented with minimal mathematical notation and a focus on concepts. This book is unique because it is authored by statisticians at the National Cancer Institute who are actively involved in the application of microarray technology. Many laboratories are not equipped to effectively design and analyze studies that take advantage of the promise of microarrays. Many of the software packages available to biologists were developed without involvement of statisticians experienced in such studies and contain tools that may not be optimal for particular applications. This book provides a sound preparation for designing microarray studies that have clear objectives, and for selecting analysis tools and strategies that provide clear and valid answers. The book offers an in depth understanding of the design and analysis of experiments utilizing microarrays and should benefit scientists regardless of what software packages they prefer. In order to provide all readers with hands on experience in data analysis, it includes an Appendix tutorial on the use of BRB-ArrayTools and step by step analyses of several major datasets using this software which is freely available from the National Cancer Institute for non-commercial use. The authors are current or former members of the Biometric Research Branch at the National Cancer Institute.  They have collaborated on major biomedical studies utilizing microarrays and in the development of statistical methodology for the design and analysis of microarray investigations. Dr. Simon, chief of the branch, is also the architect of BRB-ArrayTools.

The present work offers a snapshot of the state-of-the-art of crystallographic, analytical, and computational methods used in modern drug design and development. Topics discussed include: drug design against complex systems (membrane proteins, cell surface receptors, epigenetic targets, and ribosomes); modulation of protein-protein interactions; the impact of small molecule structures in drug discovery and the application of concepts such as molecular geometry, conformation, and flexibility to drug design; methodologies for understanding and characterizing protein states and protein-ligand interactions during the drug design process; and monoclonal antibody therapies. These methods are illustrated through their application to problems of medical and biological significance, such as viral and bacterial infections, diabetes, autoimmune disease, and CNS diseases. As approaches to drug discovery have changed over time, so have the methodologies used to solve the varied, new, and difficult problems encountered in drug discovery. In recent years we have seen great progress in the fields of genetics, biology, chemistry, and medicine, but there are still many unmet medical needs, from bacterial infections to cancer to chronic maladies, that require novel, different, or better therapies. This work will be of interest to researchers and policy makers interested in the latest developments in drug design.

An integrative approach across different scales from molecular sensing to mechanotransduction and gene modulation for physiological regulation of cellular functions will be explored, as well as applications to pathophysiological states in disease. A comprehensive understanding of the roles of physicochemical microenvironment and intracellular responses in determining cellular function in health and disease will also be discussed.

Over the last 18 years, there have been many advances in the field of intraoperative monitoring. This new edition of Neurophysiology in Neurosurgery: A Modern Approach provides updates on the original techniques, as well as other more recent methodologies that may either prove beneficial or are commonly used in neuromonitoring. The purpose of this book is to describe the integration of neuromonitoring with surgical procedures. Each methodology is discussed in detail as well as chapters describing how those methodologies are applied to multiple surgical procedures and the evidence used to support those uses. The second edition features a surgical procedure section, which focuses on specific surgical procedures and the type of monitoring used during these procedures. The original chapters have been updated, expanded, and the structure modified to ensure the book is beneficial to both physiologists and surgeons. This book is written for neurosurgeons, neurophysiologists, neurologists, anesthesiologists, interventional neuroradiologists, orthopedic surgeons, and plastic surgeons.

Antiplatelet therapy is the cornerstone of treatment of ischemic cardiovascular disease and over the last few years spectacular advancements in this field have been recorded. This is the first comprehensive handbook entirely dedicated to all the aspects of antiplatelet therapy. The book is divided into three main sections, pathophysiology, pharmacology and therapy, for a total of 23 chapters. A large group of leading experts from different European countries and from the USA, both from academia and industry, have contributed to the book. Besides a detailed overview on the pharmacology and clinical applications of all the currently used or of the novel antiplatelet agents, innovative approaches (e.g. intracellular signalling as an antiplatelet target, small RNAs as platelet therapeutics, etc.) or unconventional aspects (e.g. pharmacologic modulation of the inflammatory action of platelets are also treated. The book is oriented to both basic investigators and to clinicians involved with research on platelet inhibition or with the clinical use of antiplatelet therapies.

In 2009 the University Medicine Greifswald launched the "Greifswald Approach to Individualized Medicine" (GANI_MED) to implement biomarker-based individualized diagnostic and therapeutic strategies in clinical settings. Individualized Medicine (IM) has led not only to controversies about its potentials, but also about its societal, ethical and health economic implications. This anthology focusses on these areas and includes - next to clinical examples illustrating how the integrated analysis of biomarkers leads to significant improvement of therapeutic outcomes for a subgroup of patients - chapters about the definition, history and epistemology of IM. Additionally there is a focus on conceptual philosophical questions as well as challenges for applied research ethics (informed consent process, the IT-based consent management and the handling of incidental findings). Finally it pays attention to health economic aspects. The possibilities of IM to initiate a paradigm shift in the German health care provision are investigated. Furthermore, it is asked whether the G-DRG system is ready for the implementation of such approaches into clinical routine.

The young investigator with an idea has to negotiate many institutional, federal, and industrial challenges in order to get a product to market. Nowhere is described the steps in the development of new drugs, diagnos tics, or devices; the person with an idea has nowhere to turn for information and details. The young investigator may understand the elements of basic and clinical research, but ordinarily has no insight into novel ways of finding research funding or how to explore to find the funding opportunities that are available. The young investigator has little knowledge of the mecha nisms to bring an idea through the developmental phases to the market. There are other players in this complex endeavor with whom he or she has no contact, including those from industry, the Food and Drug Administration, and the legal community. Exposure to the philosophy of product develop ment and to procedural information would be useful to the scientific com munity, as would contact with those who have successfully taken an idea to a finished product. A first attempt to do this was the symposium on Idea to Product: The Process, sponsored by Serono Symposia USA and held No vember 17 to 20, 1994, in Washington, D.C. This book comprises the pro ceedings of that meeting. The editors are indebted to the many contributors to this volume, and we are especially grateful to Serono Symposia USA and to Leslie Nies and her staff for their expertise in organizing the symposium."

The early detection of myocardial damage is one of the major challenges in contemporary cardiology. New biochemical markers have now emerged which appear to be highly sensitive and specific for the assessment not only of patients with myocardial infarction but also of those with unstable angina and prolonged chest pains. Some of these markers, such as the troponins, have been shown to have prognostic value in the context of acute chest pain. The incorporation of novel markers of myocardial damage to the routine diagnostic armamentarium is not without difficulty. The reasons for this include cost-benefit implications and the lack of definitive comprehensive publications dealing specifically with these issues. Technical difficulties with some of the novel markers are also a problem in some cases and this issue also needs to be carefully reviewed. A critical analysis of the biochemical characteristics, sensitivity and specificity as well as the potential clinical applications of the new markers is required. This monograph addresses these issues and also sets up the basis for a redefinition of myocardial damage and myocardial infarction. The book will be of particular interest to biochemists, pharmacologists, cardiologists, general physicians and clinical and basic researchers. The important issue of myocardial damage in relation to pharmacological agents has been specifically addressed in the book and this topic will be of particular interest to both clinical pharmacologists and those working in the pharmaceutical industry. International authorities, whose original work and expertise in the field are widely recognised, have contributed chapters to the book.
