Available in PDF, EPUB and Kindle. Book excerpt: It is becoming traditional that periodically those of us interested in the carotid body hold an international meeting to discuss their results. In 1966 a meeting was organized by R. W. Torrance in Oxford and in 1973 by M. J. Purves in Bristol; in 1974 A. S. Paintal organized a satellite symposium of the Physiological Congress in Kashmir. The organizers of these meetings are to be commended for their efforts in publishing both the papers and discussions. At these meetings it has become apparent that the direction of research is becoming more sharpely focused on the cellular mechanisms of chemoreception. During the meeting in Dortmund the papers dealt mostly with the different cell types in the carotid body and their environment, i. e. , local P0 and local flow. These included 2 light and electron microscopic studies of the morphometric and histochemical pro perties of the different cells, microelectrode studies of the glomoid tissue to understand the conversion of a chemical stimulation into nervous activity, as well as strictly bio chemical and physiologic investigations concerning the dependence of the chemo receptive process on O consumption and the turnover of catecholamines. In spite 2 of the variety in methodology, it was apparent that all contributors had a common interest: to understand the mechanisms of chemoreception. Although at the meeting itself there was ample time to fully discuss the various papers, it has become necessary here to shorten the papers and discussions; otherwise the cost of publication would have been prohibitive.

Available in PDF, EPUB and Kindle. Book excerpt: This book entitled Arterial Chemoreception is an edited compilation of the oral communications and posters presented at the IXth International Sym posium on Arterial Chemoreceptors held in Park City, Utah, from August 29th to September 3rd, 1988. The Symposium also saw the formal inau guration and first meeting of the International Society for Arterial Che moreception (ISAC). In all there were 87 presentations by 108 scientists from 18 countries. Authors making multiple presentations at Park City combined their results into single, longer papers for this volume. As a result this vol~me offers the reader 63 contributions of state-of-the-art research in this important and exciting field. Inasmuch as oxygen is the substrate sine qua non for the survival of all higher organisms, it is quite understandable that considerable interest sur rounds investigations into mechanisms responsible for detecting dwindling oxygen supplies in the organism. This interest has intensified as the newer techniques of cell, sub-cell, and molecular biology have become available. As detectors of insufficient oxygen in the arterial blood the arterial che moreceptors (carotid and aortic bodies) initiate many cardiopulmonary reflexes geared toward maintaining constant the delivery of oxygen to the tissues. These chemoreceptors, which also trigger secretions from the ad renal glands, are located near the carotid sinus and in the arch of the aorta.

Available in PDF, EPUB and Kindle. Book excerpt: Arterial chemoreceptors are unique structures which continuously monitor changes in arterial blood oxygen, carbon dioxide, glucose, and acid. Alterations in these gases are almost instantaneously sensed by arterial chemoreceptors and relayed into a physiological response which restores blood homeostasis. Arterial Chemoreception contains updated material regarding the physiology of the primary arterial chemoreceptor; the carotid body. Moreover, this book also explores tantalizing evidence regarding the contribution of the aortic bodies, chromaffin cells, lung neuroepithelial bodies, and brainstem areas involved in monitoring changes in blood gases. Furthermore this collection includes data showing the critical importance of these chemoreceptors in the pathophysiology of human disease and possible therapeutic treatments. This book is a required text for any researcher in the field of arterial chemoreception for years to come. It is also a critical text for physicians searching for bench-to-bedside treatments for heart failure, sleep apnea, and pulmonary hypertension.

Book excerpt: This volume records the papers presented in Warsaw on the meeting of the International Society of Arterial Chemoreception (LS. A. C. ) organized as a Satellite Symposium of the XXXI International Congress of the Union of Physiological Sciences (I. U. P. S. ) in Helsinki in July 1989. It is a 30 years old tradition to hold periodically international meetings on recent developments in chemoreceptor research and to exchange information between those of us interested in chemoreception. The first meeting was organized by B. B. Lloyd in Oxford in 1959. Later on, similar international meetings were held at irregular intervals. In 1966, R. W. Torrance organized the second meeting again in Oxford. In 1973, the third meeting was organized in Bristol (U. K. ) by M. J. Purves. In 1974, a fourth meeting combined with the XXVI I. U. P. S. Congress in Delhi was organized by A. S. Paintal in Srinagar (Kashmir, India). In 1976, H. Acker organized the fifth meeting in Dortmund (F. R. G. ), and in 1979, C. Belmonte in Valla dolid (Spain) organized the sixth international meeting commemorating the 50th anniversary of Fernando de Castro publishing his classical work on the structure and possible function of the carotid body. In 1982, the seventh meeting was due to D. J. Pallot in Leicester (U. K. ), in 1985 - the eighth one due to A. J.

Available in PDF, EPUB and Kindle. Book excerpt: The International Society for Arterial Chemoreception (ISAC) was founded in August 1988 during the 9th International Symposium on Arterial Chemoreception which was held at Park City, Utah, USA. ISAC was established with the aim of providing a framework to support the increasing number of investigators from a wide variety of disciplines (anatomists, pathologists, respiratory physiologists and clinicians, high altitude physiologists, biochemists, biophysicists, physiologists and pharmacologists) who share a common interest in arterial chemoreception. ISAC took over the co-ordination of the international chemoreceptor meetings, with the membership deciding the venue for forthcoming meetings. During the Park City symposium Dublin was selected to host the 1993 meeting, under the Presidency of Professor Ronan O'Regan. The 12th International Meeting on Arterial Chemoreception, which was held in Dublin in August 1993, was acclaimed as a great success by all those present. The delegates not only shared in a wide-ranging feast of chemoreceptor based science, they had plenty of opportunity during the meeting for renewing acquaintances and establishing new friendships. The location for the meeting at University College Dublin's modem Belfield campus helped to promote such interaction, and the social programme was outstanding.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1959, the International Society of Arterial Chemoreception (ISAC) has organized in a variety of countries fifteen scientific meetings devoted to the mechanisms of peripheral arterial chemoreception and chemoreceptor reflexes. After the meeting held in Philadelphia with Sukhamay Lahiri as president, ISAC membership elected Lyon (CNRS, University Claude Bernard, France) as the site of the xv" ISAC Symposium. The Symposium was effectively held in Lyon from the 18th to the 22nd of November 2002 and Jean-Marc Pequignot was its president. The organizers were Jean-Marc Pequignot and Yvette Dalmaz Lyon (CNRS, University Claude Bernard, France) and the Scientific Committee was formed by John Carroll (University of Arkansas for Medical Sciences, USA), Constancio Gonzalez (University of Valladolid, Spain), Prem Kumar (University of Birmingham, U. K. ), Sukhamay Lahiri (University of Pennsylvania, Philadelphia, USA), Colin Nurse (McMaster University, Hamilton, Ontario, Canada), and Nanduri Prabhakar (Case Western University, Cleveland, Ohio, USA). The Symposium in Lyon intended to follow the path opened in Philadelphia gathering people working at the interface of cellular and molecular biology with researchers in the more classical topics of chemoreception pathways and reflexes. The aim was to join experts with different perspectives. Along these lines, some participants are engaged in the exploration of the intimate mechanisms of oxygen sensing and cellular responses, with their work centered in a great number of preparations covering a broad spectrum from bacteria, to chemoreceptor cells or to central nervous systems neurons.

This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume records the papers presented in Chieti, Italy, at the 1991 meeting of the International Society for Arterial Chemoreception (ISAC). This was the eleventh of a series of assemblies held since 1959. This field of research, which examines the critical function and mechanisms of O and pHIPC0 sensitive cells in 2 2 the body, is unique in that it encompasses diverse biological and medical areas. The reader of this book will note chapters concerning modem techniques like in situ hybridization; analysis of cell membrane channels and intracellular ion movements; immunohistochemistry of peptides, hormones, and the corresponding receptors of chemoreceptor cells; and systemic analysis of reflex pathways involving chemoreceptor cells and their meaning in health and disease. This broad spectrum will appeal to readers interested in the chemoreceptor field, as well as young scientists seeking a scientific field where not only structural analysis but also a sense for functional connections is required. In recognition of the importance of the contribution of a new scientific generation to this field, ISAC awarded the prestigious F. de Castro-C. Heymans E. Neil prize to A. G6rlach, a young scientist. Also at this meeting, the Ferdinando Data Foundation Award, for helping scientists from non-developed countries to pursue their interest in chemoreception, was initiated. ISAC held plenary lectures in honor of C. Eyzaguirre and R. Forster, both of whom have contributed greatly to research in the chemoreceptor field.

Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
