Book Synopsis Calcium in Muscle Activation by : Johann C. Rüegg
Download or read book Calcium in Muscle Activation written by Johann C. Rüegg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comparative and interdisciplinary approach to excitation-contraction-coupling in smooth and striated mus cles, including the myocardium. It is an account of the path ways and mechanisms by which cellular calcium is handled and activates the contractile proteins. It also describes how these mechanisms are adapted in various kinds of muscle to meet specific functional requirements, such as speed or economy. This monograph then presents facts, ideas and theories and the evidence on which they are based, and ifit stimulates others and furthers research, it will have served its purpose. All of the chapters are self-contained and may be read in any order, but readers unfamiliar with muscle are recommended to start with the introductory chapter on excitation and contraction. During all the years of writing this book, I received enormous help from Isolde Berger who corrected, edited and transformed my innumerable notes and drafts into a readable manuscript; she also compiled the list of references and the Subject Index. I owe a great debt of gratitude to her and also to Claudia Zeugner, who prepared the figures with expertise and care. Then I would like to thank the Deutsche F orschungs gemeinschaft and the Fritz-Thyssen-Stiftung for supporting the work of my Department which has been reported in this monograph. A great many people contributed with helpful discussions.

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Book Synopsis Excitation-Contraction Coupling in Skeletal, Cardiac, and Smooth Muscle by : George B. Frank
Download or read book Excitation-Contraction Coupling in Skeletal, Cardiac, and Smooth Muscle written by George B. Frank and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third International Symposium on Excitation-Contraction Coupling in Skeletal, Cardiac, and Smooth Muscle, organized by George Frank, C. Paul Bianchi, and Henk E. DJ. ter Keurs, was held in Banff Centre, Banff, Alberta, Canada during June 26 to June 30, 1991. The theme of these symposia has been to recognize the similarities and dissimilarities of excitation-contraction coupling in skeletal, cardiac, and smooth muscle. Cross fertilization of concepts of excitation-contraction coupling in these three types of muscle has occurred since the early studies in the late fifties and early sixties on skeletal muscle. Investigators in each field meet only at specialized symposia which exclude investigators in the other fields. The purpose of the symposia has been to bring together international investigators studying excitation-contraction coupling in skeletal, cardiac, and smooth muscle so that we may learn from each other and hence provide a more global concept of excitation-contraction. The Third International Symposia has accomplished its objective as we recognize that calcium channels of the sarcolemma and the sarcoplasmic reticulum play key essential roles in excitation-contraction coupling in all three types of muscles. In skeletal muscle the recognition that E-C coupling consists of two parallel mechanisms, one dependent upon a dihydropyridine voltage-sensitive sensors coupled to calcium release from the terminal cisternae via the ryanodine sensitive channel in the foot structure of the triad.
Book Synopsis Endocrinology of the Vasculature by : J. R. Sowers
Download or read book Endocrinology of the Vasculature written by J. R. Sowers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key workers in vascular medicine and biology apply state-of-the-art techniques in cell and molecular biology to study the endothelial and vascular smooth muscle cells. The distinguished scientists and clinicians open a new area of endocrinology, which sees the vasculature and kidney as endocrine organs and sheds new light on the hormonal regulation of the cardiovascular system. They also add significantly to our current understanding of the autocrine, paracrine, and endocrine regulation of vascular function in health and in those vascular disease states that accompany diabetes mellitus, dyslipidemia, and hypertension. Endocrinology of the Vasculature is the first book to comprehensively and systematically explore the vasculature as an endocrine organ.

This book was released on 2012-12-06 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixth Annual Graduate Hospital Research Symposium REGULATION OF SMOOTH MUSCLE PROGRESS IN SOLVING THE PUZZLE Every so often a scientific conference comes at a time when everyone has new and exciting information, when old "dogmas" do not seem to be as well established, and when speakers and participants alike are ready to challenge interpretations of old and new experimental data. This was such a conference. What turns on a smooth muscle cell? The precise answer to this question has eluded scientists for much longer than I have been involved in the field. We know that an increase in cytosolic calcium is necessary and we know that phosphorylation of the 20 kDa myosin light chain is an important step in the process. We do not know if other processes are necessary for the initiation and lor maintenance of a smooth muscle contraction nor do we know if other processes modulate the regulation of contraction. The goal of the symposium on which this volume is based was to explore the most current hypotheses for the answers to these questions. I believe that after reading the chapters included in this volume, you will agree that this goal was achieved. The importance of calcium and calmodulin dependent myosin light chain phosphoryla tion in the regulation of smooth muscle contraction was reinforced by many presentations. However, the status of myosin light chain phosphorylation as a simple calcium dependent switch came under serious suspicion.
Book Synopsis Influence of the Thin Filament Calcium Activation on Muscle Force Production and Rate of Contraction in Cardiac Muscle by : Catalina Norman
Download or read book Influence of the Thin Filament Calcium Activation on Muscle Force Production and Rate of Contraction in Cardiac Muscle written by Catalina Norman and published by . This book was released on 2007 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: These results have physiological relevance and possible clinical applications considering that, on a beat-to-beat basis, the heart contracts at submaximum Ca2+ activation. In heart failure, Ca2+ sensitizing TnC mutants would increase the rate of contraction and improve contractility, whereas in hypertrophic cardiomyopathy, Ca2+ desensitizing TnC mutants would correct for the cardiac sensitization and/or the hypercontractile state.
Book Synopsis Regulating Muscle Contraction by : Milad Webb
Download or read book Regulating Muscle Contraction written by Milad Webb and published by . This book was released on 2013 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this dissertation is to characterize the relationship between myosin ATPase kinetics, calcium sensitivity and cooperativity of thin filament activation to explain the role of calcium- and myosin-dependent activation processes observed during muscle contraction. The findings will be extended to a cardiomyocyte system developed to investigate the relationship between myosin kinetics, force generated from the sarcomere, and maladaptive phenotypic changes. Using the in vitro motility assay to simulate unloaded muscle shortening, the effect of inhibition of intermediate states of the myosin ATPase cycle was characterized. We determined that calcium sensitivity and cooperativity were modulated via perturbation of myosin duty ratio. A cardiomyocyte system for mechanical studies was developed to further investigate the role of ATPase kinetics in cardiac remodeling. This system allows for the perturbation of ATPase kinetics, as well as manipulation of various signaling pathways (which can be monitored fluorescently), while monitoring force generated internally and transferred to the extracellular environment, which is critical in the study of hypertrophic phenotypes. Collectively, our findings indicate that targeted therapeutics which modulate myosin ATPase kinetics can normalize calcium sensitivity and cooperativity in compromised cardiac tissue; and these therapeutics can be accurately evaluated and modeled in the in vitro environment.
