Interest in retinoic acid, the main biologically active derivative of vi- min A or retinol, increased dramatically between 1989 and 1993, following the cloning of nuclear receptors or RARs reported in 1987 (Fig. 1). Important discoveries since then have shown how RARs work as all-trans retinoic ac- dependent heterodimers with related nuclear receptors for 9-cis retinoic acid called RXRs. This has stimulated the development of synthetic analogs s- cific for each type of receptor, and opens the way to develop new methods for regulating pharmacologically the activity ofretinoic acid-dependent pathways of gene activation. The potential for the development of new drugs by the pharmaceutical industry is now a maj or factor driving forward our understa- ing of vitamin A-regulated pathways in animal development and homeostasis. However, apart from the real potential ofretinoid analogs as novel pharma- logical agents, there remains the considerable intellectual challenge of und- standing the way in which vitamin A and its derivatives function in cell development and differentiation. Retinoid Protocols is an attempt to bring together various methodologies that will be vital for rising to this challenge in the future. Retinoid molecular biology has few methods of its own, but is reliant on standard molecular biology methods applied to this particular research area.
This volume describes the current state of our knowledge on the neurobiology of muscle fatigue, with consideration also given to selected integrative cardiorespiratory mechanisms. Our charge to the authors of the various chapters was twofold: to provide a systematic review of the topic that could serve as a balanced reference text for practicing health-care professionals, teaching faculty, and pre-and postdoctoral trainees in the biomedi cal sciences; and to stimulate further experimental and theoretical work on neurobiology. Key issues are addressed in nine interrelated areas: fatigue of single muscle fibers, fatigue at the neuromuscular junction, fatigue of single motor units, metabolic fatigue studied with nuclear magnetic resonance, fatigue of the segmental motor system, fatigue involving suprasegmental mechanisms, the task dependency of fatigue mechanisms, integrative (largely cardiorespiratory) systems issues, and fatigue of adapted systems (due to aging, under-and overuse, and pathophysiology). The product is a volume that provides compre of processes that operate from the forebrain to the contractile proteins."
Islands are special because they promote unique forms of life, and large proportions of the species they hold are found nowhere else on Earth. The mammals of the South-west Pacific are no exception, with many distributed only across single islands or archipelagos. Mammals of the South-west Pacific details the natural history for more than 180 species of marsupials, bats and rodents from 24 Pacific nations and territories. Species profiles are accompanied by distribution maps, illustrations and photographs – many being the first images ever captured for the species. By combining available knowledge with unpublished data collected over years of field work, Mammals of the South-west Pacific forms a definitive guide to the mammals from this region.
The author makes a unique contribution to the field by discussing the history and philosophy of the neurosciences, and then developing critical approaches which integrate techniques, theory, and ethics. Taken as a whole, Jacobson's work will provide a coherent and humane framework for future research programs. The paperback edition of this highly successful text, first published in 1993, is now available! The author brings the ethics of neuroscience into a closer relationship with empirical research. Covering the field's history, philosophy, theories, and techniques, this volume provides the necessary moral and ethical framework to evaluate neuroscience research.
JOHN G. HILDEBRAND Research on insect olfaction is important for at least two reasons. First, the olfactory systems of insects and their arthropod kin are experi mentally favourable models for studies aimed at learning about general principles of olfaction that apply to vertebrates and invertebrates alike. Detailed comparisons between the olfactory pathways in vertebrates and insects have revealed striking similarities of functional organisation, physiol ogy, and development, suggesting that olfactory information is processed through neural mechanisms more similar than different in these evolution arily remote creatures. Second, insect olfaction itself is important because of the economic and medical impact of insects that are agricultural pests and disease vectors, as well as positive impact of beneficial species, such as the bees and moths responsible for pollination and production of honey. The harm or benefit attributable to an insect is a function of what it does - that is, of its behaviour - which is shaped by sensory information. Often olfaction is the key modality for control of basic insect behaviour, such as ori entation and movement toward, and interactions with, potential mates, appro priate sites for oviposition, and sources of food. Not surprisingly, therefore, much work on insect olfaction has been motivated by long-term hopes of using knowledge of this pivotal sensory system to design strategies for mon itoring and managing harmful species and fostering the welfare of beneficial ones."
This manual provides an easy guide to pain management for the veterinary practitioner. Beginning with pain terminology, it goes on to describe to physiology of pain, management strategies, various drugs and techniques, and the management of specific conditions and procedures. Strategies for the treatment of pain are comprehensively reviewed, with an overview of the mechanisms by which pain is perceived and the principles of pain management. The drugs currently used in the treatment of acute and chronic pain are discussed as well as the specific techniques that can be used to control intra- and post operative pain in dogs and cats. The book covers a broad range of information on specific aspects of pain management from analgesic techniques to management of chronic pain to pain perception. Published by Teton New Media USA and distributed by CRC Press outside of North America.
In this introductory text, Dr. Birdi demonstrates experimental methods and analyses of fractal dimensions in natural processes. In addition to a general overview, he discusses in detail problems in the fields of chemistry, geochemistry, and biophysics. Both students and professionals with a minimum of mathematics or physical science training will learn to find and model shapes and patterns from their own everyday observations.
Many organisms have evolved the ability to enter into and revive from a dormant state. They can survive for long periods in this state (often even months to years), yet can become responsive again within minutes or hours. This is often, but not necessarily, associated with desiccation. Preserving onea (TM)s body and reviving it in future generations is a dream of mankind. To date, however, we have failed to learn how cells, tissues or entire organisms can be made dormant or be effectively revived at ambient temperatures. In this book studies on organisms, ranging from aquatic cyanobacteria that produce akinetes to hibernating mammals, are presented, and reveal common but also divergent physiological and molecular pathways for surviving in a dormant form or for tolerating harsh environments. Attempting to learn the functions associated with dormancy and how they are regulated is one of the great future challenges. Its relevance to the preservation of cells and tissues is one of the key concerns of this book.
The great variety in structure and function of arthropod sensory organs is due to the huge number of species living in spatially and temporally different environments and to great variation in behavioral patterns. This atlas compiles the electron microscopic anatomy of arthropod sensory organophotoreceptors, chemoreceptors, and others in relation to function, behavior, and environment. The authors show how each sensory receptor is finely tuned to detect the necessary information in the arthropods surroundings and how the sensory receptors dynamically change their fine structures according to their functional and adaptational states. In each two-page spread of the book, electron or light micrographs are shown on the right, with diagrammatic illustrations and accompanying text on the left, in a format that is attractive and easy to understand. The atlas thus provides an important bridge between the physiology and morphology of arthropod sensory receptors.
The most recent research findings on the important genes, key
molecules, and mechanisms in neural development and regeneration
are presented in this volume. The papers collected here were
delivered at the second of the Keio University International
Symposia for Life Sciences and Medicine, held in Mita (Tokyo),
Japan, and are in eight main sections: Early Neurogenesis and
Pattern Formation, Regional and Cellular Specification, Trophic
Factors, Adhesion Molecules, Glial Cell Lineage and Myelination,
Circuit Formation, Synaptic Refinement and Neurotransmitter
Release, and Neural Regeneration. Together, they present the
concept of neural development and regeneration and its vital
importance at the frontiers of medical science today.
This new series on The Biochemistry and Molecular Biology of Fishes
grew out of the demand for state-of-the-art review articles in a
rapidly expanding field of research. Up to the present, most
research literature on biochemistry involved rats and humans, but
new breakthroughs in the piscine setting have indicated that the
field is ready for a review series of its own. Because of funding
and experimental availability restrictions, most research in the
field has dealt with fish and insects. Within the insect field,
comparative biochemistry and comparative physiology have proceeded
along independent paths as opposed to the piscine field, where the
tendency has been for the latter to envelop the former.
Here is the first effort in a single volume to cover all of the integrative functions of calcium signalling - how changes in intracellular calcium coordinate a variety of coherent cellular responses. Written by a team of internationally established researchers, Integrative Aspects of Calcium Signalling provides the latest experimental data and concepts, bringing together a detailed analysis of the events, processes, and functions regulated by calcium signalling. A unique resource for professionals and students of physiology, biophysics, neurobiology, biochemistry, and all related fields.
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.
The overall scope of this new series will be to evolve an understanding of the genetic basis of (1) how early mesoderm commits to cells of a heart lineage that progressively and irreversibly assemble into a segmented, primary heart tube that can be remodeled into a four-chambered organ, and (2) how blood vessels are derived and assembled both in the heart and in the body. Our central aim is to establish a four-dimensional, spatiotemporal foundation for the heart and blood vessels that can be genetically dissected for function and mechanism. Since Robert DeHaan's seminal chapter "Morphogenesis of the Vertebrate Heart" published in Organogenesis (Holt Rinehart & Winston, NY) in 1965, there have been surprisingly few books devoted to the subject of cardiovascular mor phogenesis, despite the enormous growth of interest that occurred nationally and internationally. Most writings on the subject have been scholarly compilations of the proceedings of major national or international symposia or multiauthored volumes, often without a specific theme. What is missing are the unifying concepts that can make sense out of a burgeoning database of facts. The Editorial Board of this new series believes the time has come for a book series dedicated to cardio vascular morphogenesis that will serve not only as an important archival and didac tic reference source for those who have recently come into the field but also as a guide to the evolution of afield that is clearly coming of age.

With more than 2200 references to assist further research, Molybdenum and Tungsten: Their Roles in Biological Processes is an essential resource for scientists and students in many disciplines, including bioinorganic, inorganic, and coordination chemistry; biochemistry; biophysics; molecular biology; enzymology; pharmacology; physiology; clinical chemistry; nutrition; toxicology; and environmental sciences.
Primate locomotion has typically been studied from two points of view. Laboratory-based researchers have focused on aspects like biomechanics and energetics, whereas field-based researchers have focused on (locomotor) behaviour and ecology. Unfortunately, to date, there is relatively little scientific exchange between both groups. With a book, which will be the result of a symposium on the 2008 Meeting of the International Primatological Society in Edinburgh, we would like to bring together laboratory and field-based primate locomotion studies. We are convinced this will be beneficial for both research lines. For example, biomechanists might wonder how frequently the locomotor style they study in the lab actually occurs in nature, and field workers might use calculated costs of locomotion to understand why certain locomotor behaviours are favoured under specific conditions. Thus, on the one hand, an established link between both groups may help interpret the results by using each other's findings. On the other hand, recent technological advances (e.g. portable high-speed cameras) make it possible to bridge the gap between lab-based and field-based research by actually collecting biomechanical data in situ. Again, communication between both groups is necessary to identify the specific needs and start up achievable and successful research projects in the field. In order to generate a wide interest, we have invited biomechanists, ecologists, and field-based researchers who combine both disciplines, and we hope their combined contributions will facilitate lasting cooperation between the mentioned disciplines and stimulate innovative research in Primatology. We are convinced that the most appropriate format to publish the different symposium contributions is a conference volume within an existing book series. Firstly, the chapters will not only contain new data but will also review existing data and elaborate on potential future work - more so than can be done in a journal article. Secondly, the combination of chapters will form an entity that is more valuable than the sum of the separate chapters and therefore they need to be presented together. Lastly, this volume will benefit from the typically long "shelf life" of a book in a renowned series, allowing it to be used as reference book for both researchers and students.
"Environment and Animal Development "is the first book to focus specifically on the interactions between the environment and developmental mechanisms with particular emphasis given to the consequences for animal populations. The underlying premise of the book is that the study of physiological mechanisms alongside the analysis of adaptive values will enable rapid advancements in our knowledge of this important field. With contributions from well-known experts, the book will be invaluable for all graduate students and researchers in this area.
Because of developments in powerful computer technology, computational techniques, advances in a wide spectrum of diverse technologies, and other advances coupled with cross disciplinary pursuits between technology and its greatly significant applied implications in human body processes, the field of biomechanics is evolving as a broadly significant area. The four volumes of Biomechanical Systems: Techniques and Applications presents the advances in widely diverse areas with significant implications for human betterment that occur continuously at a high rate. These include dynamics of musculo-skeletal systems; mechanics of hard and soft tissues; mechanics of muscle; mechanics of bone remodeling; mechanics of implant-tissue interfaces; cardiovascular and respiratory biomechanics; mechanics of blood flow, air flow, flow-prosthesis interfaces; mechanics of impact; dynamics of man machine interaction; and numerous other areas. The great breadth and depth of the field of biomechanics on the international scene requires at least four volumes for adequate treatment. These four volumes constitute a well integrated set that can be utilized as individual volumes. They provide a substantively significant and rather comprehensive, in-depth treatment of biomechanic systems and techniques that is most surely unique on the international scene.
The bright colour of haemoglobin has, from the very beginning,
played a significant role in both the investigation of this
compound as well as in the study of blood oxygen transport.
Numerous optical methods have been developed for measuring
haemoglobin concentration, oxygen saturation, and the principal
dyshaemoglobins in vitro as well as in vivo. Modern applications
include pulse oximeters, fibre optic oximeters, multiwavelength
haemoglobin photometers ('co-oximeters') and instruments for near
infrared spectroscopy in vivo. Knowledge of the light absorption
spectra of the common haemoglobin derivatives is a prerequisite for
the development and understanding of these techniques.
Myofibrillogenesis has been studied extensively over the last 100 years. Until recently, we have not had a comprehensive understanding of this fundamental process. The emergence of new technologies in molecular and cellular biology, combined with classical embryology, have started to unravel some of the complexities of myofibril assembly in striated muscles. In striated muscles, the contractile proteins are arranged in a highly ordered three dimensional lattice known as the sarcomere. The assembly of a myofibril involves the precise ordering of several proteins into a linear array of sarcomeres. Multiple isoforms in many of these proteins further complicate the process, making it difficult to define the precise role of each component. This volume has been compiled as a comprehensive reference on myofibrillogenesis. In addition, the book includes reviews on myofibrillar disarray under various pathological conditions, such as familial hypertrophic cardiomyopathy (FHC), and incorporates a section on the conduction system in the heart. Much of the information in this volume has not been described elsewhere. Presented in a manner to be of value to students and teachers alike, "Myofibrillogenesis" will be an invaluable reference source for all in the fields of muscle biology and heart development.
There is increasing concern in the media, among politicians and within environmental organizations, about the effects of chemicals in our environment that affect the endocrine systems of wildlife and humans. At its simplest these are referred to as gender-bending' chemicals or environmental estrogens'. The chemicals in question (pesticides, PCBs, plasticizers, petrochemicals, and a variety of industrial chemicals) have been known to decrease human sperm counts, cause fish to change sex', and increase male genital abnormalities. A great deal of pressure has been placed on environmental protection agencies to devise regulatory tests for the effects of these chemicals and to require limitations on their manufacture and release. Fish are increasingly recognized as an excellent model for such tests, in that the aquatic environment may provide early warnings of the effects that these chemicals will have on human health. In addition, the large number of eggs which fish produce provides an excellent model to examine the effects on female fertility. Endocrine Disruption in Fish provides a simple yet extensive background to the field of fish endocrinology in order to assist those toxicologists who have a limited background in either mammalian or fish endocrinology. It shows that environmental estrogens do not simply affect male reproductive potential, but that they may equally well affect the female. It is possible that these chemicals may have a complex effect on the brain, hypothalamus, pituitary, gonad and liver of both sexes. There are many other chemicals which affect both the gonads and other parts of the endocrine system to cause decreased fertility, abnormal sexual differentiation andbehavior, decreased response to stress, immune deficiency or altered basal metabolism. Many thousand man-made chemicals are released into the environment, but very few have been tested for endocrine disrupting activity. This book covers only the minute fraction for which evidence has been collected.
This book reviews all major models and hypotheses concerning the mechanisms supposed to underlie the process of navigation in vertebrates. It covers data on all major model groups of vertebrates studied in the context of animal navigation, such as migratory birds, homing pigeons, sea turtles, subterranean mammals and some migratory fish species. Some other - less studied - groups, e.g., whales, have also been touched. The first part of the book describes different sources of navigational information, with their specific navigational mechanisms known or supposed to be employed by animals for navigational goals. The second part discusses possible functions of these mechanisms in different vertebrates and in the context of different navigational tasks, ranging from short-range navigation, often performed by animals within as small an area as several square meters, to long-distance global-scale migrations performed by many birds and some sea turtles during their lifespan.
Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species: (a) Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. (b) Trans-specific communication with non-related organisms. (c) Species-specific communication between same or related species. (d) Intraorganismic communication, i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms. "
This is the first book devoted to international deer husbandry techniques for the growing industries of venison, velvet antler, and antler trophy production as well as long established extensive park systems for amenity. Written by world leaders in their specialised subjects, chapters shed light on widely differing management systems and the optimum design of deer farms, handling yards and fencing layouts. Moreover, readers will discover the requisites of good stockmanship and specialist veterinarians describe different diseases the deer may develop. Details on available treatments, the general biology of deer and an explanation of controversial ethics of velvet and trophy production complete this work. As deer farming has come of age this collection is timely. At fifty years the New Zealand deer industry carries one million animals with annual venison exports to America, Europe and growing antler markets in China and Korea. Chinese antler production is well-established and Asian reindeer husbandry even more ancient. In North America and Europe, deer are now being kept for antler trophies and amenity in many historic parks. This volume is a valuable resource for everyone researching deer management systems, be it practising veterinarians, deer farmers, park managers or agricultural and veterinary students. |
