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.

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

It will be a valuable resource for endocrinologists, diabetes specialists, internists and family practitioners.

This volume summarizes recent advances in research on mesenchymal cell populations in the bone marrow. It explores how mesenchymal cells create niches for immune cells in extramedullary organs and it discusses new concepts of lympho-hematopoietic microenvironments. Readers are introduced to the fundamentals of hematopoietic stem cells (HSCs) differentiation to all types of blood cells, including immune cells, in the bone marrow. The book highlights how this process is supported and regulated by the individual microenvironments of stem cells, termed niches. The identity of HSC niches has been subject to longstanding debates. Recent studies identified the population of mesenchymal stem cells as the major cellular component of niches, for hematopoietic stem and progenitor cells (HSPCs) and their candidate developmental origin. Furthermore, candidate cellular niches for immune cells in lymph nodes and adipose and connective tissues were identified. The authors of this volume focus on shared features between those and HSPC niche cells in the bone marrow. Covering latest research results, this book serves as fascinating read for researchers and clinicians in hematology and immunology.

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.

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.

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.

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.

Chapters also discuss the clinical implications of histamine receptor antagonists.

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.

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.

In this book, expert researchers present their findings on molecular and physiological/pathological aspects of 5-HT2B receptors. The molecular section includes a discussion of the genetics of 5-HT2B receptors and impulse control. The physiological section covers their role in many biological systems including the nervous system, the heart, and the lungs.

Only recently have we begun to appreciate the role of microbiome in health and disease. Environmental factors and change of life style including diet significantly shape human microbiome that in turn appears to modify gut barrier function affecting nutrient & electrolyte absorption and inflammation. Approaches that can reverse the gut dysbiosis represent as reasonable and novel strategies for restoring the balance between host and microbes. In the book, we offer summary and discussion on the advances in understanding of pathophysiological mechanisms of microbial host interactions in human diseases. We will not only discuss intestinal bacterial community, but also viruses, fungi and oral microbiome. Microbiome studies will facilitate diagnosis, functional studies, drug development and personalized medicine. Thus, this book will further highlight the microbiome in the context of health and disease, focusing on mechanistic concepts that underlie the complex relationships between host and microbes.

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.

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.

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.

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.
