Bioimaging in life sciences is a burgeoning area that is of growing interest to today's professionals and researchers in the field. This is the first book that bridges the gap between biomedical imaging and the bioscience community. This unique resource gives professionals a detailed understanding of imaging platforms, fluorescence imaging, and fundamental image processing algorithms. Further, it guides readers through the application of advanced image analysis methods and techniques to specific biological problems. The book presents applications that span a wide range of scales, from the detection of signaling events in sub-cellular structures, to the automated analysis of tissue structures. Other critical areas discussed include the dynamics of cell populations and in vivo microscopy. A DVD is also included. It contains full-color images, movies and other valuable supplementary material that further illustrate topics discussed in the book.
Our planet is crowded with a spectacular diversity of living creatures. As a most peculiar fact, the oldest of these are in general the most primitive whereas the most recent are the most advanced. How can evolution be working in order to bring about such a counterintuitive result? This raises the challenging question of a direction of evolution. Is it proceeding in a certain direction, is it improving, is it even accelerating? By introducing the concept of complexity, the author suggests a new way of describing the process of evolution. In this conception, the human cultural evolution is found to be a continuous extension of biological evolution in a common process of ever increasing complexity, characterized as a stepwise, cumulative progression. What is man's place in this process? Is it meaningful to reflect upon this at all? In fact, in asking this very question we have at the same time answered it. No other creature would. Our brains provide us with a fantastic range of exclusive cognitive abilities and in this respect we are unique. In this book, we embark on an innovative, exploratory and inter-disciplinary adventure, step by step following the author towards his quest of investigating evolution, its direction and the place of ourselves in it.
The isolation of leptin in 1994 and its characterization as a factor influencing appetite, energy balance, and adiposity, immediately thrust the polypeptide into the rapidly growing body of literature centered on the physiology of obesity. The growing clinical awareness of obesity as a major health risk in developed societies dovetailed perfectly with any of a number of roles that leptin might play in this abenant physiological condition. Almost unnoticed amidst the excitement generated by early leptin publications was the suggestion that the "fat hormone" might also regulate a wide range of systems and events important to reproduction, including pubertal development, gonadal endocrinology, fettility, and pregnancy. Recognizing this potential, a relatively small cadre of researchers began to examine leptin specifically as a reproductive hormone, thus creating a new and fertile field of investigation. Interest in this area has since gained momentum and an increased number of participants have now made significant contributions to our understanding of many leptin-related mechanisms that are relevant to reproductive biology. Leptin and Reproduction is the first major volume to specifically address leptin as a reproductive hormone and closely examines the advances made in the short time since this field of interest developed. Preeminent researchers ti'om many of the subdisciplines working within this area present a welcomed compendium of the wealth of related literature and voice novel interpretations of cun'ent advances.
This volume not only discusses various common biobanking topics, it also delves into less-discussed subjects such as what is needed to start a biobank, training of new biobanking personnel, and ethnic representation in biospecimen research. Other chapters in this book span practical topics including: disaster prevention and recovery; information technology; flora and fauna preservation including zoological fluid specimen photography; surgical and autopsy biobanking; biobanking of bodily fluids; biosafety; cutting frozen sections; immunohistochemistry; nucleic acid extraction; and biospecimen shipping. 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. Unique and comprehensive, Biobanking: Methods and Protocols is a valuable resource for novice and practicing biobankers, and for end-user researchers. This book aims to bring new insight into the field and expand on current biomedical biobanking studies.
From cell division to heartbeat, clocklike rhythms pervade the activities of every living organism. The cycles of life are ultimately biochemical in mechanism but many of the principles that dominate their orchestration are essentially mathematical. The Geometry of Biological Time describes periodic processes in living systems and their non-living analogues in the abstract terms of nonlinear dynamics. Enphasis is given in phase singularities, waves, and mutual synchronization in tissues composed of many clocklike units. Also provided are descriptions of the best-studied experimental systems such as chemical oscillators, pacemaker neurons, circadian clocks, and excitable media organized into biochemical and bioelectrical wave patterns in two and three dimensions. No theoretical background is assumed; the required notions are introduced through an extensive collection of pictures and easily understood examples. This extensively updated new edition incorporates the fruits of two decades' further exploration guided by the same principles. Limit cycle theories of circadian clocks are now applied to human jet lag and are understood in terms of the molecular genetics of their recently discovered mechanisms. Supercomputers reveal the unforeseen architecture and dynamics of three-dimensional scroll waves in excitable media. Their role in life-threatening electrical aberrations of the heartbeat is exposed by laboratory experiments and corroborated in the clinic. These developments trace back to three basic mathematical ideas.
In a ?rst approximation, certainly rough, one can de?ne as non-crystalline materials those which are neither single-crystals nor poly-crystals. Within this category, we canincludedisorderedsolids,softcondensed matter,andlivesystemsamong others. Contrary to crystals, non-crystalline materials have in common that their intrinsic structures cannot be exclusively described by a discrete and periodical function but by a continuous function with short range of order. Structurally these systems have in common the relevance of length scales between those de?ned by the atomic and the macroscopic scale. In a simple ?uid, for example, mobile molecules may freely exchange their positions, so that their new positions are permutations of their old ones. By contrast, in a complex ?uid large groups of molecules may be interc- nected so that the permutation freedom within the group is lost, while the p- mutation between the groups is possible. In this case, the dominant characteristic length, which may de?ne the properties of the system, is not the molecular size but that of the groups. A central aspect of some non-crystalline materials is that they may self-organize. This is of particular importance for Soft-matter materials. Self-organization is characterized by the spontaneous creation of regular structures at different length scales which may exhibit a certain hierarchy that controls the properties of the system. X-ray scattering and diffraction have been for more than a hundred years an essential technique to characterize the structure of materials. Quite often scattering anddiffractionphenomenaexhibitedbynon-crystallinematerialshavebeenreferred to as non-crystalline diffraction.
Bioinformatics is an evolving field that is gaining popularity due to genomics, proteomics and other high-throughput biological methods. The function of bioinformatic scientists includes biological data storage, retrieval and in silico analysis of the results from large-scale experiments. This requires a grasp of knowledge mining algorithms, a thorough understanding of biological knowledge base, and the logical relationship of entities that describe a process or the system. Bioinformatics researchers are required to be trained in multidisciplinary fields of biology, mathematics and computer science. Currently the requirements are satisfied by ad hoc researchers who have specific skills in biology or mathematics/computer science. But the learning curve is steep and the time required to communicate using domain specific terms is becoming a major bottle neck in scientific productivity. This workbook provides hands-on experience which has been lacking for qualified bioinformatics researchers.
For the first time a compilation of chapters that depict the biological bases underlying the development of lentiviral vectors, the techniques involved in the manufacture of this new gene delivery tool, and its most promising applications.
The first book of Failure Analysis Case Studies selected from
volumes 1, 2 and 3 of the journal "Engineering Failure Analysis"
was published by Elsevier Science in September 1998. The book has
proved to be a sought-after and widely used source of reference
material to help people avoid or analyse engineering failures,
design and manufacture for greater safety and economy, and assess
operating, maintenance and fitness-for-purpose procedures. In the
last three years, "Engineering Failure Analysis" has continued to
build on its early success as an essential medium for the
publication of failure analysis cases studies and papers on the
structure, properties and behaviour of engineering materials as
applied to real problems in structures, components and design.
Apoptosis is a form of cell death that occurs in a controlled manner and is generally noninflammatory in nature. Apoptosis, or programmed cell death, implies a cell death that is part of a normal physiological process of pruning of unneeded cells. However, many disease conditions utilize apoptosis for pathological ends, resulting in inappropriate cell death and tissue destruction. This book starts with an introduction that reviews the general characteristics of apoptosis, its regulation and its role in physiology and disease. Next, the book focuses on three areas as they relate to inflammatory cells and diseases. The first area consists of chapters on signals for apoptosis important to inflammatory cells, namely growth factors and arachidonic acid metabolism. The next area that the book focuses on are effects at the cellular level, on cell survival versus cell death and signals critical for cell function in both normal and disease states. These topics are covered in chapters on lymphocytes, granulocytes, chondrocytes and keratinocytes. The last area that the book focuses on are events at the level of tissue and disease, looking at the evidence for altered apoptosis and/or apoptotic processes in immune and inflammatory diseases. These topics are covered in chapters on rheumatoid arthritis, osteoarthritis, lupus, psoriasis and renal disease. Together, these chapters will provide the reader with the latest insight in the role of apoptosis in inflammatory cells and diseases.

Electron Paramagnetic Resonance (EPR) Volume 17 highlights major developments in this area reported up to the end of 1999, with results being set into the context of earlier work and presented as a set of critical yet coherent overviews. The topics covered describe contrasting types of application, ranging from biological areas such as EPR and ENDOR studies of metalloproteins and evidence of free-radical reactions in biology and medically-related systems, to experimental developments and applications involving EPR imaging, the use of very high fields, and time-resolved methods. Critical reviews of applications involving bacterial photosynthesis, spin-labelling and spin-probes studies of self-assembled systems, and organometallic chemistry are also included. As EPR continues to find new applications in virtually all areas of modern science, including physics, chemistry, biology and materials science, this series caters not only for experts in the field, but also those wishing to gain a general overview of EPR applications in a given area. Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.
leading to an overall decrease in the world's forest cover. The forests of Asia, in particular, have been strongly impacted. A number of initiatives have suggested forest policy reforms, and the need for the sustainable management of forests has been widely recognized and encouraged. But because implementation of reforms at the local level has been insufficient, it is imperative that local people begin to effectively participate in forest planning and management as well as in protected-area management. The Forest Conservation Project, launched in April 1998 by the Institute for Global Environmental Strategies (IGES), has carried out research activities on forest strategies, including policy analysis and on-site surveys. This book gives an overview of the project's research activities in its first three-year phase (April1998-March 2001). Since viable forest strategies work best when based on the involvement of local people, this report is addressed to stakeholders in the communities of the relevant countries, including local people and authorities, community-based organizations, experts, national agencies, and international institutions.
Probabilistic Modelling in Bioinformatics and Medical Informatics has been written for researchers and students in statistics, machine learning, and the biological sciences. The first part of this book provides a self-contained introduction to the methodology of Bayesian networks. The following parts demonstrate how these methods are applied in bioinformatics and medical informatics. All three fields - the methodology of probabilistic modeling, bioinformatics, and medical informatics - are evolving very quickly. The text should therefore be seen as an introduction, offering both elementary tutorials as well as more advanced applications and case studies.
This thesis presents a new method for following evolving interactions between coupled oscillatory systems of the kind that abound in nature. Examples range from the subcellular level, to ecosystems, through climate dynamics, to the movements of planets and stars. Such systems mutually interact, adjusting their internal clocks, and may correspondingly move between synchronized and non-synchronized states. The thesis describes a way of using Bayesian inference to exploit the presence of random fluctuations, thus analyzing these processes in unprecedented detail. It first develops the basic theory of interacting oscillators whose frequencies are non-constant, and then applies it to the human heart and lungs as an example. Their coupling function can be used to follow with great precision the transitions into and out of synchronization. The method described has the potential to illuminate the ageing process as well as to improve diagnostics in cardiology, anesthesiology and neuroscience, and yields insights into a wide diversity of natural processes.
Major improvements in instrumentation and specimen preparation have brought SEM to the fore as a biological imaging technique. Although this imaging technique has undergone tremendous developments, it is still poorly represented in the literature, limited to journal articles and chapters in books. This comprehensive volume is dedicated to the theory and practical applications of FESEM in biological samples. It provides a comprehensive explanation of instrumentation, applications, and protocols, and is intended to teach the reader how to operate such microscopes to obtain the best quality images.
This book contains an interesting and state-of the art collection of chapters presenting several examples of attempts to developing modern tools utilizing computational intelligence in different real life problems encountered by humans. Reasoning, prediction, modeling, optimization, decision making, etc. need modern, soft and intelligent algorithms, methods and methodologies to solve, in the efficient ways, problems appearing in human activity. The contents of the book is divided into two parts. Part I, consisting of four chapters, is devoted to selected links of computational intelligence, medicine, health care and biomechanics. Several problems are considered: estimation of healthcare system reliability, classification of ultrasound thyroid images, application of fuzzy logic to measure weight status and central fatness, and deriving kinematics directly from video records. Part II, also consisting of four chapters, is devoted to selected links of computational intelligence and biology. The common denominator of three chapters is Physarum polycephalum, one-cell organisms able to build complex networks for solving different computational tasks. One chapter focuses on a novel device, the memristor, that has possible uses both in the creation of hardware neural nets for artificial intelligence and as the connection between a hardware neural net and a living neuronal cell network in the treatment and monitoring of neurological disease. This book is intended for a wide audience of readers who are interested in various aspects of computational intelligence.
Plant based Biotechnology has come to represent a means of mitigating the problems of global food security in the twenty first century. Products and processes in agriculture are increasingly becoming linked to science and cutting edge technology, to enable the engineering of what are in effect, designer plants. One of the most successful, non chemical approaches to pest management and disease control, which seeks a solution in terms of using living organisms to regulate the incidence of pests and and pathogens, providing a `natural control' while still maintaining the biological balance with the ecosystem. This volume, describes the various biological agents used to control insect pests of a variety of crops. Readers may also be interested in Volume 1: Crop diseases, Weeds and Nematodes, published in December 2000, ISBN 0-306-46460-8.
There are only very few chemical classes of antibiotics in medical use, and these have originated over a span of more than 60 years of research. Almost half a century ago, the first member of the macrolides, erythromycin, was introduced as a treatment option for bacterial infections. Erythromycin is a very complex fermentation product obtained from the soil bacterium Saccharopolyspora ery thraea (originally named Streptomyces erythreus). The success of erythromycin, based on its efficacy and tolerability, stimulated researchers throughout the world to undertake intense efforts to understand the biology and chemistry of macrolides and to use this experience to improve the properties of this compound class. The second generation of macrolides, based on chemical modifications of erythromy cin, is currently being in broad use, especially for treatment of respiratory tract infections. We presently foresee the introduction of a new generation of macro lides, i. e. the ketolides, which have the potential to overcome rising resistance problems. This monograph is intended to give the interested reader an overview on "macrolide experience," covering important areas from basic research to clinical use. Starting from a historic overview, the essential basic parameters - efficacy, pharmacokinetics, pharmacodynamics, and pharmacology - are highlighted in order to introduce the reader to the rationale for clinical use of macrolides. The following group of chapters cover the complex chemistry of the macro lactone structures, giving historic background, basic structure-activity relation ships of various derivatization strategies, and perspectives for future discovery of new semisynthetic macrolide antibiotics." |
