New Frontiers in Respiratory Control by Ikuo Homma,Hiroshi Onimaru,Yoshinosuke Fukuchi Pdf

Breathing is performed by the rhythmic contraction of respiratory muscles. It ma- tains homeostasis of the organism by taking in the oxygen necessary to live and work and by controlling the level of CO within the organism. At first glance, breathing 2 seems simple; however, it is produced by a complex system in the brain with various afferents and efferents. The control of breathing is of the utmost importance in s- taining life, and although more than 150 years have passed since research on brea- ing control was first begun, many unsolved mysteries still remain. Breathing is like watching the tides at a beach that are created by the vast, complex open sea. The first Oxford Conference on Modeling and Control of Breathing was held 30 years ago in September of 1978 at the University Laboratory of Physiology in Oxford, England. During this first conference, the participants engaged in a hot d- cussion on the problem of whether breathing rhythm was produced by pacemaker cells or a neural network. This was before the discovery of the Bötinger complex in the medulla, and at the time, central chemoreceptive areas were still the focus of research. This conference was an especially unforgettable moment in the dawning of the new age of respiratory research. It has since been held every 3 years in various countries around the globe and is widely appreciated as the best respiratory meeting in the world.

Modelling Parasite Transmission and Control by Edwin Michael,Robert C. Spear Pdf

It is clear that many fascinating problems still remain to be addressed in parasite transmission modelling, from better understanding of transmission processes and natural history of infection to investigating the impact of ecological and spatial scales, climate change, host immunity and social behaviour, parasite-host evolutionary dynamics and parasite community ecology on parasite transmission. This book captures some of the advances made in recent years and provides indications of ways forward for addressing these questions by shedding light on developments in conceptual frameworks and modelling tools as well as the emergence of new data forms for aiding model construction, testing and analysis. Another important advance has been the parallel development of robust computationally-intensive statistical methods to allow model testing and parameterization by aiding the fitting of models to complex data. This is an exciting area of work, which we believe will broaden the scope of mathematical modelling in investigating parasite transmission processes. In particular, we expect this advance will now allow modellers to begin the successful development and analysis of mechanistically-rich models of parasite transmission that will facilitate better integration of the variety of mechanisms increasingly recognized as important in simultaneously affecting transmission, including abiotic processes, trophic and evolutionary interactions, movement in space, and behaviour and even physiology of the individual. We foresee a continuing bright future for using mathematical modelling to clarify parasite transmission dynamics and address problems related to effective parasite control. Ultimately, through this improved application of models to research and management, we expect that parasite control would be an achievable goal bringing benefits to a vast number of our fellow human beings.

Respiratory Biology of Animals by Steven F. Perry,Markus Lambertz,Anke Schmitz Pdf

Oxygen uptake for metabolic energy demand and the elimination of the resulting carbon dioxide is one of the essential processes in all higher life forms; in the case of animals, everything from protozoans to insects and vertebrates including humans.� Respiratory Biology of Animals provides a contemporary and truly integrative approach to the topic, adopting a strong evolutionary theme. It covers aerobic metabolism at all levels, from gas exchange organs such as skin, gills, and lungs to mitochondria - the site of cellular respiration. The book also describes the functional morphology and physiology of the circulatory system, which often contains gas-carrying pigments and is important for pH regulation in the organism. A final section describes the evolution of animal respiratory systems. Throughout the book, examples are selected from the entire breadth of the animal kingdom, identifying common themes that transcend taxonomy. Respiratory Biology of Animals is an accessible supplementary text suitable for both senior undergraduate and graduate students taking courses in respiratory biology, comparative animal physiology, and environmental physiology. It is also of relevance and use to the many professional academics requiring a concise but authoritative overview of the topic.

Frontiers in Brain Repair by Rahul Jandial Pdf

In the rapidly-evolving landscape of neurosciences, it is no easy task to select a limited array of topics to present in a text such as this. The current volume takes as its purpose to provide a representative survey of the current science of brain repair for those seeking to establish a foundation in the field or to replenish a prior knowledge base that may have lapsed in its currency. It also hopes to offer insights into what remains elusive to our collective investigations, defining the “frontiers” of brain repair for those that are currently immersed in the exciting intersection of biological advances and neuroscientific discoveries. In Chapter 1 the fundamentals of imaging transplanted cells is discussed with emphasis on animal models as well as the horizon for clinical trials. Then, detailed methods on the culture of neural stem cells is reviewed as a foundation for approaching therapeutic goals. Chapter 3 presents the broad scope of animal models that serve as the foundation for developmental and pre-clinical investigation, with mention of recent genetically engineered mouse models that represent the best models for studying disease development and treatment. Chapter 4 provides background on the delivery techniques to animals and patients that are available, providing vital information on the subtleties of technique necessary for optimal cellular grafting. Chapters 5 and 6 discuss new and evolving information on the origins of brain tumors and the indelible role of stromal and microenvironmental influences on oncogenesis and tumor progression. Subsequently, the utility of neural stem cells as cellular vehicles to deliver chemotherapeutics to broad neuropathology is reviewed. In Chapter 8 the scope of treating brain tumors is expanded beyond stem cells, to present the best biological interventions to improve upon current treatment options for brain malignancy. The last two chapters present a comprehensive review on stem cell and gene therapy options for treating cerebrovascular and neurovascular pathology. In amassing this collection, my intention has been to provide the reader with a broad introduction into molecular imaging, stem cell biology, cell therapy, animal models, central nervous system malignancies, stroke, and neurodegeneration. My hope is that Frontiers of Brain Repair will be the intellectual soil from which a deeply rooted and well-nourished vintage of neuroscience will arise.

Proteins by Gregor Anderluh,Jeremy H. Lakey Pdf

Formation of transmembrane pores is a very effective way of killing cells. It is thus not surprising that many bacterial and eukaryotic toxic agents are pore-forming proteins. Pore formation in a target membrane is a complex process composed of several steps; proteins need to attach to the lipid membrane, possibly aggregate in the plane of the membrane and finally form a pore by inserting part of the polypeptide chain across the lipid bilayer. Structural information about toxins at each stage is indispensible for the biochemical and molecular biological studies that aim to - derstand how pores are formed at the molecular level. There are currently only two Staphylococcus aureus and hemolysin E from Escherichia coli. Therefore, what we know about these proteins was obtained over many years of intense experimentation. We have nevertheless, in the last couple of years, witnessed a significant rise in structural information on the soluble forms of pore-forming proteins. Surprisingly, many unexpected similarities with other proteins were noted, despite extremely low or insignificant sequence similarity. It appears that lipid membrane binding and formation of transmembrane channels is achieved in many cases by a limited repertoire of structures. This book describes how several of the important pore forming toxin families achieve membrane bi- ing and which structural elements are used for formation of transmembrane pores. Our contributors have thus provided the means for a comparative analysis of several unrelated families.

Integrins and Ion Channels by Andrea Becchetti,Annarosa Arcangeli Pdf

Interdisciplinarity is more often invoked than practised. This is hardly surprising, considering the daunting vastness of modern biology. To reach a satisfactory understanding of a complex biological system, a wide spectrum of conceptual and experimental tools must be applied at different levels, from the molecular to the cellular, tissue and organismic. We believe the multifaceted regulatory interplay between integrin receptors and ion channels offers a rich and challenging field for researchers seeking broad biological perspectives. By mediating cell adhesion to the extracellular matrix, integrins regulate many developmental processes in the widest sense (from cell choice between differentiation and proliferation, to tissue remodeling and organogenesis). Rapidly growing evidence shows that frequent communication takes place between cell adhesion receptors and channel proteins. This may occur through formation of multiprotein membrane complexes that regulate ion fluxes as well as a variety of intracellular signaling pathways. In other cases, cross talk is more indirect and mediated by cellular messengers such as G proteins. These interactions are reciprocal, in that ion channel stimulation often controls integrin activation or expression. From a functional standpoint, studying the interplay between integrin receptors and ion channels clarifies how the extracellular matrix regulates processes as disparate as muscle excitability, synaptic plasticity and lymphocyte activation, just to mention a few. The derangement of these processes has many implications for pathogenesis processes, in particular for tumor invasiveness and some cardiovascular and neurologic diseases. This book provides a general introduction to the problems and methods of this blossoming field.

Polyploidization and Cancer by Randy Y.C. Poon Pdf

Limiting genome replication to once per cell cycle is vital for maintaining genome stability. Although polyploidization is of physiologically importance for several specialized cell types, inappropriate polyploidization is believed to promote aneuploidy and transformation. A growing body of evidence indicates that the surveillance mechanisms that prevent polyploidization are frequently perturbed in cancers. Progress in the past several years has unraveled some of the underlying principles that maintain genome stability. This book brings together leaders of the field to overview subjects relating to polyploidization and cancer.

Cardiovascular and Respiratory Systems by Jerry J. Batzel,Franz Kappel,Daniel Schneditz,Hien T. Tran Pdf

Cardiovascular and Respiratory Systems: Modeling, Analysis, and Control uses a principle-based modeling approach and analysis of feedback control regulation to elucidate the physiological relationships. Models are arranged around specific questions or conditions, such as exercise or sleep transition, and are generally based on physiological mechanisms rather than on formal descriptions of input-output behavior. The authors ask open questions relevant to medical and clinical applications and clarify underlying themes of physiological control organization. Current problems, key issues, developing trends, and unresolved questions are highlighted. Researchers and graduate students in mathematical biology and biomedical engineering will find this book useful. It will also appeal to researchers in the physiological and life sciences who are interested in mathematical modeling.

Biosurfactants by Ramkrishna Sen Pdf

The microbial world has given us many surprises including microbes that grow under extremely harsh conditions (122C at 40 MPa), novel metabolisms such as the uranium and perchlorate reduction, and novel chemicals that can be used to control diseases. We continually face new and difficult problems such as the need to transition to more carbon-neutral energy sources and to find eco-friendly chemicals and to find new drugs to treat disease. Will it be possible to tap into the seemingly limitless potential of microbial activity to solve our current and future problems?The answer to this question is probably yes. We are already looking to the microbial world to provide new energy sources, green chemicals to replace those made from petroleum, and new drugs to fight disease. To help us along these paths, we are deciphering how microorganisms interact with each other. We know that microbial populations interact and communicate with each other. The language that microbes use is chemical where small molecules are exchanged among different microbial cells. Sometimes, these chemicals suppress activities of competitors and could be used as antibiotics or may have other therapeutic uses. Other times, the chemicals stimulate complex responses in microbial populations such as fruiting body or biofilm formation. By understanding the conversation that microbes are having among themselves, e. g.

Disease Control Priorities, Third Edition (Volume 5) by Dorairaj Prabhakaran,Shuchi Anand,Thomas A. Gaziano,Jean-Claude Mbanya,Rachel Nugent Pdf

Cardiovascular, respiratory, and related conditions cause more than 40 percent of all deaths globally, and their substantial burden is rising, particularly in low- and middle-income countries (LMICs). Their burden extends well beyond health effects to include significant economic and societal consequences. Most of these conditions are related, share risk factors, and have common control measures at the clinical, population, and policy levels. Lives can be extended and improved when these diseases are prevented, detected, and managed. This volume summarizes current knowledge and presents evidence-based interventions that are effective, cost-effective, and scalable in LMICs.
