Cell-cell and cell-matrix interactions are of fundamental
importance for the development and the maintenance of tissues and
organs in multicellular organisms. Adhesive processes are mediated
and controlled by an increasingly large and complex number of cell
adhesion molecules that are anchored to the cell surface membrane
by transmembrane domains. According to their structural and
functional features, cell adhesion molecules have been classified
into at least four major families: the integrins, selectins,
cadherins and members of the immunoglobulin superfamily. Apart from
linking cells to each other or to components of the extracellular
matrix, cell adhesion molecules function also as receptors that
interact via their cytoplasmic domain with numerous signalling
molecules including protein kinases and phosphatases, G-proteins,
or proteins of the beta-catenin/armadillo family. Cell adhesion
molecules can activate various signalling pathways and as a
consequence play a crucial role in the regulation of cell
differentiation, proliferation, migration and apoptosis. During the
last decade it has been recognized that acquired as well as
inherited defects of cell adhesion molecules and adhesion-linked
signalling molecules are the molecular basis of various types of
disease including cancer, infectious and inflammatory disease,
connective tissue disorders or blistering disease.
Focusing on assessment through therapist-driven protocols, this valuable tool provides an overview of the assessment process and fundamentals needed for success. It offers discussion of the top five treatment protocols: oxygen, hyperinflation , bronchial hygiene and bronchodilator therapies, as well as mechanical ventilation. Using a case study approach, students learn to manage an entire case from beginning to end. Each time they assess the patient, they use the SOAP format: Subjective, Objective, Assessment, and Plan reasoning, giving them practice in documenting history and developing care plans.
Regulated turnover of extracellular matrix (ECM) is an important component of tissue homeostasis. In recent years, the enzymes that participate in, and control ECM turnover have been the focus of research that touches on development, tissue remodeling, inflammation and disease. This volume in the Biology of Extracellular Matrix series provides a review of the known classes of proteases that degrade ECM both outside and inside the cell. The specific EMC proteases that are discussed include cathepsins, bacterial collagenases, matrix metalloproteinases, meprins, serine proteases, and elastases. The volume also discusses the domains responsible for specific biochemical characteristics of the proteases and the physical interactions that occur when the protease interacts with substrate. The topics covered in this volume provide an important context for understanding the role that matrix-degrading proteases play in normal tissue remodeling and in diseases such as cancer and lung disease. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology.
From humble beginnings over 25 years ago as a lipid kinase activity associated with certain oncoproteins, PI3K (phosphoinositide 3-kinase) has been catapulted to the forefront of drug development in cancer, immunity and thrombosis, with the first clinical trials of PI3K pathway inhibitors now in progress. Here we give a brief overview of some key discoveries in the PI3K area and their impact, and include thoughts on the current state of the field, and where it could go from here
This unique and authoritative book presents an up-to-date overview of the many aspects of energy balance and its relationships to disease processes resulting from excess energy consumption and storage. It provides a comprehensive treatment of important research and clinical aspects of energy metabolism and obesity. It will be a valuable resource for endocrinologists, diabetes specialists, internists and family practitioners.
This volume represents the first collection of articles contributed by research leaders working on the Myb family of transcriptional regulatory proteins. In more than twenty chapters the authors discuss the range of biological processes and diverse cell types in which Myb proteins operate. Although concentrating on the three vertebrate Myb family members, homologues from lower species are also discussed because of the light they are able to shed on the evolution and function of these proteins. Individual chapters describe the involvement of Myb proteins, in particular c-Myb, in normal and diseased development and function of many tissues including haemopoietic cells, blood vessels, the gastrointestinal tract and the brain. Several chapters explore the mechanistic details of the action of Myb proteins, especially structural features, their interaction with DNA and other regulatory proteins, and the variety of genes that are regulatory targets for this group of transcription factors. This work will be of interest to those working directly in the field and also to the wider research community investigating the transcriptional regulation of development, differentiation and growth. The therapeutic potential of manipulating Myb function is also discussed making the book appealing to clinician scientists in several fields including haematology, oncology and cardiology.
Spanning biological, mathematical, computational, and engineering sciences, computational biofluiddynamics addresses a diverse family of problems involving fluid flow inside and around living organisms, organs, tissue, biological cells, and other biological materials. Computational Hydrodynamics of Capsules and Biological Cells provides a comprehensive, rigorous, and current introduction to the fundamental concepts, mathematical formulation, alternative approaches, and predictions of this evolving field. In the first several chapters on boundary-element, boundary-integral, and immersed-boundary methods, the book covers the flow-induced deformation of idealized two-dimensional red blood cells in Stokes flow, capsules with spherical unstressed shapes based on direct and variational formulations, and cellular flow in domains with complex geometry. It also presents simulations of microscopic hemodynamics and hemorheology as well as results on the deformation of capsules and cells in dilute and dense suspensions. The book then describes a discrete membrane model where a surface network of viscoelastic links emulates the spectrin network of the cytoskeleton, before presenting a novel two-dimensional model of red and white blood cell motion. The final chapter discusses the numerical simulation of platelet motion near a wall representing injured tissue. This volume provides a roadmap to the current state of the art in computational cellular mechanics and biofluiddynamics. It also indicates areas for further work on mathematical formulation and numerical implementation and identifies physiological problems that need to be addressed in future research.

This book reports the text of the lectures of the 6th International Conference on Sodium Calcium Exchange held in Lacco Ameno in the Island of Ischia in the Gulf of Naples, Italy, from October 1 to October 5, 2011. The present book uncovers the most striking new findings on NCX that emerged since the previous Conference on Sodium Calcium Exchange, such as the structural dissection of the molecular determinants of Ca2+ sensitivity of the exchanger, the epigenetic regulation of ncx1 gene, the molecular identification of the mitochondrial Sodium Calcium Exchanger, and the discovery of NCX in unexpected anatomical locations such as the female reproductive tract. The book is organized into 11 parts covering NCX structural aspects, genetic and epigenetic regulation, regulatory mechanisms, subcellular localization in mitochondria, involvement in neurodegenerative diseases and in immune regulation, and the role of the cardiovascular and endocrine systems, as well as diabetes in physiology and pathophysiology. Selected chapters of the book are also devoted to the interaction of NCKX and other ion channels and transporters with NCX, like ASICs, TRPM, and NHE.
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.

In 1898, an Austrian microbiologist Heinrich Winterberg made a curious observation: the number of microbial cells in his samples did not match the number of colonies formed on nutrient media (Winterberg 1898). About a decade later, J. Amann qu- tified this mismatch, which turned out to be surprisingly large, with non-growing cells outnumbering the cultivable ones almost 150 times (Amann 1911). These papers signify some of the earliest steps towards the discovery of an important phenomenon known today as the Great Plate Count Anomaly (Staley and Konopka 1985). Note how early in the history of microbiology these steps were taken. Detecting the Anomaly almost certainly required the Plate. If so, then the period from 1881 to 1887, the years when Robert Koch and Petri introduced their key inventions (Koch 1881; Petri 1887), sets the earliest boundary for the discovery, which is remarkably close to the 1898 observations by H. Winterberg. Celebrating its 111th anniversary, the Great Plate Count Anomaly today is arguably the oldest unresolved microbiological phenomenon. In the years to follow, the Anomaly was repeatedly confirmed by all microb- logists who cared to compare the cell count in the inoculum to the colony count in the Petri dish (cf., Cholodny 1929; Butkevich 1932; Butkevich and Butkevich 1936). By mid-century, the remarkable difference between the two counts became a universally recognized phenomenon, acknowledged by several classics of the time (Waksman and Hotchkiss 1937; ZoBell 1946; Jannasch and Jones 1959).
This book gathers together contributions from internationally renowned authors in the field of cardiovascular systems and provides crucial insight into the importance of sex- and gender-concepts during the analysis of patient data. This innovative title is the first to offer the elements necessary to consider sex-related properties in both clinical and basic studies regarding the heart and circulation on multiscale levels (i.e. molecular, cellular, electrophysiologically, neuroendocrine, immunoregulatory, organ, allometric, and modeling). Observed differences at (ultra)cellular and organ level are quantified, with focus on clinical relevance and implications for diagnosis and patient management. Since the cardiovascular system is of vital importance for all tissues, Sex-Specific Analysis of Cardiovascular Function is an essential source of information for clinicians, biologists, and biomedical investigators. The wide spectrum of differences described in this book will also act as an eye-opener and serve as a handbook for students, teachers, scientists and practitioners.
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.

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.
