Cardiac ion channels and mechanisms for protection against atrial fibrillation. Intrinsically photosensitive retinal ganglion cells. Quantifying and modeling the temperature-dependent gating of TRP channels.
Since the first gap junction protein (connexin) was cloned over a decade ago, more than a dozen connexin genes have been cloned. Consequently, a wealth of information on the molecular basis of gap junctional communication has been accumulated. This book pays tribute to this exciting era in the history of cell communication research by documenting the great strides made in this field as a result of the merging of biophysics and molecular biology, two of the most powerful approaches to studying the molecular basis of membrane channel behavior. Twenty-eight comprehensive chapters, authored by internationally recognized leaders in the field, discuss the biophysical, physiological, and molecular characteristics of cell-to-cell communication via gap junctions. Key aspects of molecular structure, formation, gating, conductance, and permeability of vertebrate and invertebrate gap junction channels are highlighted. In addition, a number of chapters focus on recent discoveries that implicate connexin mutations and alterations of gap junctional communication in the pathogenesis of several diseases, including the X-linked Charcot-Marie-Tooth demyelinating disease, some forms of inherited sensorineural deafness, malignant transformation, cardiac malformations and arrhythmia, eye lens cataract, and Chagas disease.
Sunao Tawara's epoch-making work on the excitation conduction system of the mammalian heart paved the way for the advancement of modern cardiology in the 20th century. Even today, more than 90 years after the publication of the German monograph "Das Reizleitungssystem des Saugetierherzen", his precise account of the conduction system from the atrioventricular node through the His-Purkinje system to the ordinary ventricular muscle fibers retains all of its original actuality.This English edition of Tawara's monograph will serve as an invaluable reference for both basic and clinical cardiological research in the years ahead.
Considerable evidence exists that visual sensory information is analyzed simultaneously along two or more independent pathways. In the past two decades, researchers have extensively used the concept of parallel visual channels as a framework to direct their explorations of human vision. More recently, basic and clinical scientists have found such a dichotomy applicable to the way we organize our knowledge of visual development, higher order perception, and visual disorders, to name just a few. This volume attempts to provide a forum for gathering these different perspectives.
When we walk, drive a car, or fly an airplane, visual motion is
used to control and guide our movement. Optic flow describes the
characteristic pattern of visual motion that arises in these
situations. This book is the first to take an in-depth look at the
neuronal processing strategies that underlie the brain's ability to
analyze and use optic flow for the control of self-motion. It does
so in a variety of species which use optic flow in different
behavioral contexts. The spectrum ranges from flying insects to
birds, higher mammals and man. The contributions cover
physiological and behavioral studies as well as computational
models. Neuronal Processing of Optic Flow provides an authoritative
and comprehensive overview of the current state of research on this
topic written by a group of authors who have made essential
contributions to shaping this field of research over the last ten
years.
This book is an essential handbook on bisphosphonates, the most
widely used new class of drugs for osteoporosis therapy. It reviews
basic physiology in addition to the indications and adverse
reactions of these drugs. Bisphosphonates in Bone Disease, 4E,
discusses the compounds' chemistry, mechanisms of action, and
animal toxicology before presenting a clinical picture of the
diseases treated by bisphosphonates. The book provides a table
listing the trade names of the commercially available
bisphosphonates, registered indications, and the available forms
for various countries. The revised Fourth Edition contains
approximately 50% new material, including information on all of the
latest drugs.
Protein conversion from a water-soluble native conformation to the insoluble aggregates and fibrils, which can deposit in amyloid plaques, underlies more than 20 human diseases, representing a major public health problem and a scientific challenge. Such a conversion is called protein misfolding. Protein misfolding can also involve errors in the topology of the folded proteins and their assembly in lipid membranes. Lipids are found in nearly all amyloid deposits in vivo, and can critically influence protein misfolding in vitro and in vivo in many different ways. This book focuses on recent advances in our understanding of the role of lipids in modulating the misfolding of various proteins. The main emphasis is on the basic biophysical studies that address molecular basis of protein misfolding and amyloid formation, and the role of lipids in this complex process.
Gert Ter Horst and a panel of recognized experts illuminate the complexities and importance of heart-brain and brain-heart interactions in human health. These distinguished authorities critically review what is known about autonomic control of the heart, hypothalamo-pituitary- adrenal modulation, heart pain, modulation by humoral factors, and the relationship between cognitive/neuropsychiatric disorders and heart disease. Highly relevant and up-to-date, The Nervous System and the Heart offers the first comprehensive treatment of the important mutual interactions of the heart and the brain. By integrating specialist knowledge in cardiology with that from neuroscience, this important book constitutes a brilliant guide to today's novel approaches to neural control of the heart and consequent reduction of cardiovascular mortality.
In this volume of Reviews of Physiology, Biochemistry and Pharmacology there a contributions by M.D. Swope, E. Lolis, F.Hofmann, L. Lacinova, N. Klugbauer, M. Hermann, P. Berger, S.S. Shen, J.S. Kim, M.E. Weksler, M. Hirsch-Kauffmann and M.Schweiger.
Anesthetics produce a reversible state of unconsciousness accompanied by ante- grade amnesia. This remarkable phenomenon brings great relief to surgical patients and wonder to clinicians and scientists. To date, we do not fully understand the mechanisms by which anesthetics ablate conscious sensation and memory. We are, however, making progress. This book presents original results as well as overviews of the current state of knowledge of the problem. It is authored by investigators who know the ?eld well; their research at a number of levels has contributed substantially to our c- rent understanding of anesthetic modulation of memory and consciousness. Most of the contributors were presenters at two workshops organized by Dr. Pearce and Dr. Hudetz at the 40th Annual Winter Conference on Brain Research, held at Snowmass Village, Colorado, from January 27 through February 2, 2007. One workshop focused on anesthetic modulation of consciousness and another on an- thetic modulation of memory. Seven of the chapters are based on material presented at these symposia - appropriately updated with new relevant ?ndings. This infor- tion is supplemented by chapters on anesthesia and sleep, computational analysis of the state of anesthesia, and the clinical phenomenon of "anesthesia awareness," a topic that has recently received much public attention. With these three additional contributions, the book thus includes 10 chapters.
Well known experts in the field of Chronobiology from around the world, provide an integrative view of the state of the art of circadian biology. At present, genetic and epigenetic interaction of regulatory pathways among circadian oscillators, metabolic networks, cellular differentiation and neuronal communication are subject of intense scrutiny. The book is organized in three sections: The first includes selected examples of the circadian systems of crustaceans, insects, fish, birds and mammals. The second is a detailed view of the physiological mechanisms underlying the circadian clocks in mammals. Finally, in the third section some examples of the relevance of circadian biology and circadian misalignment to health and disease are provided including nutrition and metabolism, obesity, cancer, cardiovascular and pulmonary diseases, Huntington and affective diseases. This section concludes with a brief review on gene therapy and its potential use as a therapeutic tool to correct "clock genes" pathologies. This book is aimed at all those interested in contemporary aspects of physiology, biochemistry and molecular biology applied to the study and characterization of timing systems.. It could be used as an initial approach to this field, but it also provides updated information for those already familiar with the fascinating field of Chronobiology.
This collection of contributions on the subject of the neural mechanisms of sensorimotor control resulted from a conference held in Cairns, Australia, September 3-6, 2001. While the three of us were attending the International Union of Physiological Sciences (IUPS) Congress in St Petersburg, Russia, in 1997, we discussed the implications of the next Congress being awarded to New Zealand. We agreed to organise a satellite to this congress in an area of mutual interest -the neuroscience of movement and sensation. Australia has a long-standing and enviable reputation in the field of neural mechanisms of sensorimotor control. Arguably this reached its peak with the award of a Nobel Prize to Sir John Eccles in 1963 for his work on synaptic transmission in the central nervous system. Since that time, the subject of neuroscience has progressed considerably. One advance is the exploitation of knowledge acquired from animal experiments to studies on conscious human subjects. In this development, Australians have achieved international prominence, particularly in the areas of kinaesthesia and movement control. This bias is evident in the choice of subject matter for the conference and, subsequently, this book. It was also decided to assign a whole section to muscle mechanics, a subject that is often left out altogether from conferences on motor control. Cairns is a lovely city and September is a good time to visit it.

Platelets are fragments of blood cells that occur in the blood of
vertebrates and are associated with blood clotting. Scientists have
made great strides in recent years in understanding what stimulates
platelets to form blood clots at the molecular level and in
developing drugs to inhibit platelet action. Their work has a
direct effect on millions of people who deal with cardiovascular
disease, strokes, surgery, physical trauma, and other conditions.
While references to platelet function have been included in some
large texts, there has not been a basic reference manual that
researchers and clinicians can use in their daily work until
now.

The book describes spirometry and the peak flow meter as existing tools in assessing asthma along with their limitations. In addition, a detailed description of capnography as a new approach is included with various studies conducted on its analysis. Academicians and researchers in biomedical engineering, particularly in the course of biomedical signal processing and biomedical instrumentation will find the book useful.
It has been over 40 years since the original report by Salmon and Daughaday demon strating that the ability of GH to stimulate sulfation of cartilage was mediated by a "sulfation factor. " In the ensuing decades, it has become apparent that this "sulfation factor activity" encompasses a complex system ofligands (IGFs), receptors, and carrier proteins that are, in tum, responsible for a wide array of cellular actions. The IGF system has been demonstrated to be critically involved in both intrauterine and postnatal growth, and to have important implications in cancer biology as well, owing to the ability of the IGFs to function in endocrine, paracrine, and autocrine modes and given the wide distri bution of IGFs in virtually every organ system. The contributions to The /GF System reflect the wide span of interest in the IGF system and its implications for normal and abnormal growth and metabolism. The chapters have been divided into four broad sections: I. Molecular biology of the IGF system; II. Bio logical actions of the IGFs; III. IGF physiology; and IV. Clinical aspects of the IGFs. We have made every effort to highlight the major contemporary themes in IGF biology, but as is inevitable in such a fast-moving field, perspectives will continue to change as new information is accumulated."
This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.
This book is written to help and enable students in how to observe biological specimens in terms of viscosity, mass, elasticity and work producing elements. The observations are related to underlying chemical reactions by means of strain (fractional length change) sensitivity of the reactions, and a theory is developed how to connect these. Their mathematical derivation is complex when three or more states are involved, but a method is presented here to demonstrate how to simplify this complex problem. Basic mathematical solutions that are useful for this book, are presented (Fourier and Laplace transforms, differential equations, matrix operations) together with Fortran programs in the Appendix.
Hematopoietic Stem Cells Development brings together articles covering the biology of hematopoietic stem cells during embryonic development, reporting particular aspects of fly, fish, avian and mammalian models. Thus, this book allows a comparative overview of hematopoietic stem cell generation in the different classes, emphasizing the conserved trends in development. This book culminates with state-of-the art knowledge on hematopoietic development in human species and discussions of the most recent breakthroughs with relevance to both researchers and clinicians.
The immune system is not bound by a single tissue but is instead bestowed with the challenge of warding off invading pathogens throughout the body. Constant surveillance of the body requires that the immune system be highly mobile and able to purge pathogens from all tissues. Because each tissue presents its own unique architecture and milieu, it is necessary for the immune system to be as malleable as it is dynamic. For example, how the immune system handles a pathogen in the lung can differ significantly from a pathogen encountered in the gut. Understanding immune complexity in diverse tissue environments is a challenge for researchers. However, advances in imaging have greatly improved our ability to probe the immune system. From snap-shots in time to 4D movies, imaging systems have been used to generate stunning visualizations of immune cells in action throughout the body. These visualizations are not only aesthetically pleasing but they have yielded great advances in our understanding of immune function. This volume provides a synopsis of major insights in immunology revealed using imaging approaches. "Seeing is truly believing," and this volume was assembled to recognize past accomplishments and to provide visions of what the future holds in store in this exciting field.
When we began to organize the workshop "Calcium and Cellular Metabolism: Transport and Regulation" the goal we had in mind was to put together the knowledge of 2 several specialists on Ca + homeostasis, with various examples of cellular metabolisms 2 2 (such as protein synthesis), regulated by Ca + ions. Regarding the homeostasis of Ca + ions, we invited Ernesto Carafoli to write the first chapter as a general state-of-the-art introductory review. On the other hand, the other chapters are the contribution of different specialists on membrane calcium transport mechanisms, aiming to reunite at least in part the wide field of calcium homeostasis. We roughly try to group chapters that share similar subjects. The first group of chapters (Chapters 2 to 6), are mainly related to calcium channels. Thus, Chapter 2 by Rodolfo Llimis et a . describes a new concept related to the dimen sions of the calcium action domain at the inner mouth of calcium channels in the squid gi ant synapse and its relationship to neurotransmitter release. Chapter 3 by Martin Morad et a . informs us about new ways of identifying and measuring, by confocal microscopy, in dividual sites where calcium release occurs in ventricular myocytes. In the same group Osvaldo Uchitel and Eleonora Katz classify and evaluate the variety of calcium channels at the neuromuscular junction, in Chapter 4. Chapter 5 by Gustavo Brum et a ."
This ground-breaking book brings together researchers from a wide range of disciplines to discuss the control and coordination of processes involved in perceptually guided actions. The research area of motor control has become an increasingly multidisciplinary undertaking. Understanding the acquisition and performance of voluntary movements in biological and artificial systems requires the integration of knowledge from a variety of disciplines from neurophysiology to biomechanics.
