This book was released on 2012-12-06 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Paul Cranefield published his monograph, The Conduction of the Cardiac Impulse, in 1975, much has been learned about the role of the slow inward current in cardiac electrophysiology. Because of this expanse in know ledge, both basic and clinical, it appeared reasonable to review in a mono graph once again what was known. When Martinus Nijhoff first approached us to undertake the task of updating this information, we were initially reluctant for several reasons. First, we did not feel that the subject could be adequately and thoroughly reviewed, from the cell to the bedside, by a single person. Second, time constraints on all of us precluded even attempting such a task. However, we were encouraged by several of our friends (' egged on' one might even say, since they wished the job done but did not want to do it themselves!) who promised faithfully to contribute chapters on time if we accepted the task. So we did, and most of them did also.
Download or read book Electrogenesis of Biopotentials in the Cardiovascular System written by Nicholas Sperelakis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1979 Dr Sperelakis published the `Origin of the Cardiac Resting Potential' in the Handbook of Physiology of the Heart. Since that time, many investigators and teachers of membrane biophysics have used this article as a source of reference on the fundamental principles and equations describing the factors that establish the resting potential in excitable and non-excitable cells. Professor Sperelakis has expanded the scope of this article to provide the present book, creating a comprehensive work and an invaluable reference on the electrophysiological concepts underlying cellular excitability. There has long been a need for a text which precisely defines the assumptions underlying the derivations and equations that describe the principles of electrical excitability and maintenance of ion gradients in excitable cells. Here, Professor Sperelakis not only defines the equations and underlying concepts of membrane potentials, but gives working examples of solutions, thus allowing investigators to utilize the fundamental principles in their research, and students of membrane physiology to establish a sound basis of electrophysiological theory. `I have used the `Origin of the Cardiac Resting Potential' in graduate courses on cell physiology and biophysics, and look forward to using this new book. The time and effort required to put this work together reflects the dedication of Dr Sperelakis to the field of membrane biophysics and electrophysiology in his long, productive career.' From the Foreword by Dr David R. Harder.

Download or read book Cardiac Rate and Rhythm written by L.N. Bouman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the denervated state the mammalian heart, both in vivo and in vitro, is excited at very regular intervals, the coefficient of variance of the interbeat intervals not exceeding 2%. The pacemaker that is the source of this regular ex citation is localised normally within the sinus node (" sino-atrial node " node of Keith and Flack), a most intriguing small piece of tissue in the caval corner of the right atrium. A small portion of this node containing a group of probably only a few thousands of cells fires spontaneously, that means without any exter nal influence to trigger their activity. The so called pacemaker cells do this by letting their membrane potential fall to the level where an action potential will start which subsequently activates surrounding cells to fire an action po tential. The first question which is tackled in this book is which processes underly this spontaneous diastolic depolarization. This is discussed in section I, concerning the fundamental properties of pacemaker cells with special refer ence to ionic membrane currents. Although views still quite differ about the exact nature of the membrane processes that cause the automatic pacemaker dis charge there is agreement that diastolic depolarization is brought about by the interaction of a number of ionic current systems, including both inward and out ward going currents.

Download or read book Structure and Function of the Circulation written by Colin J. Schwartz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to produce a superior scholarly treatise in bio medical science, three important conditions need to be met. First, the subject needs to be of recognized importance and preferably one in which a sizeable volume of new knowledge has been added recently. Second, it needs to be quite evident that the field involved re quires much more up-to-date coverage than it has received and third, the choice of the editors and in turn the authors needs to be recognized as outstanding. This major treatise fills these criteria in an admirable way. There are few who would deny the importance of knowledge concerning the circulatory system. This all pervasive system is the route by which virtually all of the cells and tissues of the body receive their nutrition and it is the major route by which metabolic waste products are carried away. Furthermore, the diseases that involve the circulatory system are, by far, the underlying causes of death and morbidity in the largest number of Americans, Western Europeans and several other populations of industrialized nations. Not only is atherosclerosis-induced-ischemic disease of the heart, brain and extremities widespread in these populations but venous occlusive disease also takes a great toll from phlebothrombosis, pulmonary embolism, etc.
Download or read book Applied Bioelectricity written by J. Patrick Reilly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric currents and electromagnetic fields have been applied to biological systems, particularly humans, with both therapeutic and pathological results. This text discusses biological responses to electric currents and electromagnetic fields, including medical applications and shock hazards. It covers fundamental physical and engineering principles of responses to short-term electrical exposure and emphasises human reactions, although animal responses are considered as well, and the treatment covers reactions from the just-detectable to the clearly detrimental. An important new chapter discusses standards for human exposure to electromagnetic fields and electric current and demonstrates how these standards have been developed using the principles treated in earlier chapters.
Download or read book Gap Junctions Molecular Basis of Cell Communication in Health and Disease written by and published by Academic Press. This book was released on 1999-12-22 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Sinus Node written by F.I. Bonke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the clinician the sinus node is more or less a hidden structure and only by indirect assessment he is able to say something about the function of this center of pacemaker activity. The morphologist, however, is able to describe the structural microscopic and even electronmicroscopic features of this structure. The only disadvantage is that, as soon as he is coming into the picture, the tissue is dead. The physiologist tries to investigate the electrophysiological behavior of the sinus node. Since there is not a human being willing to give his sinus node for research, he has to do his investigation on isolated preparations of animals. Though there are a lot of experts in the field of the sinus node they nearly never speak the same 'language'. Therefore, it was my dream to bring all those people - or at least some of them -together on a workshop. I had the feeling that it was important to organize such a meeting without an audience but only with 'experts'.

This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of cardiac ion channels and transporters has advanced remarkably in the last two decades with the development of patch-clamp and molecular biological techniques. This textbook offers a comprehensive overview of structures and functions of ion channels and transporters in the heart. Readers are first introduced to the molecular biology and electrophysiology of all the important ion channels. After discussing their developmental changes, the pharmacology and pathophysiology of clinically-relevant ion channels are reviewed. Molecular aspects of the cardiac excitation-contraction coupling and intracellular Ca2+ regulation by ion transporters are also described. The book will be useful to electrophysiologists, cardiac physiologists and pharmacologists, and molecular biologists interested in ion channels at all levels. For research specialists, the book will provide a perspective of the field. The book can be used as a reference source for working scientists in the fields of ion channels, biophysics, cardiac electrophysiology, and pharmacology. It is aimed at graduate and medical students, designed for use as a textbook for graduate and medical courses.
Download or read book Handbook of Stable Strontium written by Stanley Skoryna and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly two hundred years ago Crawford and Cruickshank, surgeons and chemists in the Royal Artillery, reported the occurrence of a "new earth" in the mines at the Scottish village of Strontian. Humphrey Davy, following the advice of Berzelius, isolated stable strontium in 1808 along with other alkali earth metals. It was not until 1883 that physiological effects of stable strontium were first recognized by none other than Sidney Ringer in his experiments on frog heart. The medicinal use of strontium salts was first described in Squire's Companion in 1894. Subsequently, strontium was introduced into the Pharma copeias of Great Britain, United States, France, Germany, Spain, Italy, and Mexico and was used in treatment of a variety of disease. s, clearly without detailed knowledge of its actions. It is hoped that this handbook will provide a sound basis for further research on stable strontium and the establishment of the levels of intake, necessary or desirable, in different pathophysiological conditions. The objective of this publication was to assemble a comprehensive collection of essays on stable strontium which review the respective areas of research as well as present original data. I consider myself fortunate to have been able to work with the contributors of these essays. It is obvious that this type of book should be interdisciplinary in nature owing to the necessity of examining each subject from the viewpoint of different disciplines.
