Download or read book Role of the Sarcoplasmic Reticulum in Smooth Muscle written by Derek J. Chadwick and published by John Wiley & Sons. This book was released on 2003-07-07 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smooth muscle contraction is a vital component of the functioning of blood vessels, the uterus, airways and the bladder. Its malfunction can lead to serious pathological conditions, such as hypertension and pre-term labour. The calcium ion plays a central role in smooth muscle function, increasing in concentration for contraction and decreasing for relaxation. Calcium entry into the cell is facilitated by the sarcoplasmic reticulum (SR). This book explores the latest research on the role of the sarcoplasmic reticulum (SR) in smooth muscle function. It examines the control and modulation of the SR and how this may vary among smooth muscle types. Potential therapeutic implications are also discussed. Discusses new and exciting work in this area and identifies promising new research directions. Considers the advances in this relatively unexplored field, offering new insights into the role of the SR muscle. Brings together contributions from key workers, both in basic and clinical science, whose studies range from physiological to pathological and molecular to whole animal.

Book excerpt: Muscle cells, including cardiomyocytes, contain a specialized smooth endoplasmic reticulum (ER), sarcoplasmic reticulum (SR) calcium ions (Ca2+) release and reuptake by the sarcoplasmic reticulum trigger the contraction and relaxation of the myofibrils, respectively. This book examines the control and modulation of the SR and how this may vary among skeletal and cardiac muscle without bypassing the smooth muscle. It presents new and exciting work in this area and identifies promising new research directions. Furthermore, it considers the advances in this relatively unexplored field, offering new insights into the role of SR communication with other organelles and the new concepts about ER stress. Generally, this scientific book brings together contributions from key workers--both in basic and clinical sciences-- whose studies range from physiological to pathological and molecular to whole animal. In this book, the authors provide insights into the evolution of SR design and function.
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.

Download or read book Gastrointestinal Motility written by D. Grundy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basis of this book is a ten-lecture course on the control of gastrointesti nal motility given each year to the final year undergraduate students in Physiology at Sheffield University. A naive thought led me to believe that the conversion of my lecture notes into the present book would be a relatively easy task. I now know differently. As there is no equivalent undergraduate course elsewhere that I know of, it would be dishonest of me to claim this book to be an undergraduate text. The comprehensive way in which I have dealt with the subject, together with the inclusion of the most up-to-date material, make the book more relevant to postgraduate students of physiology, medicine and related sciences who require an introduction to the field of gastrointestinal motility and its control. I have, however, attempted to present the current concepts on the physiological mechanisms regulating motility in a way which under graduates, as well as postgraduates, will find readable, informative and, hopefully, enjoyable.
Download or read book Cellular Aspects of Smooth Muscle Function written by C. Y. Kao and published by Cambridge University Press. This book was released on 1997-08-28 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smooth muscles line many internal organs and, in general, are involved in moving fluids and slurry around the body. They are controlled by the action of hormones, by nervous stimulation, and can be influenced by drugs. This 1997 book provides a review of our understanding of smooth muscle and integrates molecular, cellular and physiological information with tissue and anatomical studies. Well-known researchers have written chapters giving detailed reviews of our current knowledge of the biochemistry, pharmacology, physiology and anatomy of smooth muscle. In particular, they cover the seven most important areas of smooth muscle function including morphology, electrophysiology, mechanisms of electromechanical and pharmacomechanical coupling, calcium homeostasis, signal transduction, mechanics of contraction, and the contractile proteins. All those interested in muscular contraction will find this book worthwhile, whether they are biochemists, physiologists, or cell biologists.

Download or read book Vascular Ion Channels in Physiology and Disease written by Irena Levitan, PhD and published by Springer. This book was released on 2016-07-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are the major class of membrane proteins responsible for rapid and regulated transport of ions across biological membranes and for the generation and propagation of electrical signals in the brain, heart, and skeletal and vascular tissues. Ion channels are also known to play critical roles in regulation of cell proliferation, insulin secretion and intracellular signaling in a variety of cell types. This book focuses on the roles of ion channels in vascular tissues under normal and pathological conditions. Vascular abnormalities are known to underlie a plethora of severe pathological conditions, such as atherosclerosis, systemic and pulmonary hypertension, coronary or cerebral vasospasm, and diabetes. In addition, misregulated angiogenesis is one of the major contributors to the development of tumors. Therefore, it is clearly imperative to obtain a better understanding of the molecular mechanisms that contribute to vascular disorders. This book will be the first comprehensive assembly of assays to present the studies that have been done during the last decade to elucidate the roles of ion channels in different vascular diseases.
Download or read book An Introduction to Smooth Muscle Mechanics 2nd Edition written by Chun Y. Seow and published by Cambridge Scholars Publishing. This book was released on 2020-11-13 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition is an updated version of an introductory level textbook intended for students who are interested in understanding the mechanical properties of smooth muscle. Compared with skeletal and cardiac muscles, smooth muscle is the least understood in terms of its contraction mechanism and the structure of its contractile apparatus. Nevertheless, it is an important tissue that is vital in many organ functions, such as blood pressure control, intestinal peristalsis, and the emptying of the bladder. Dysfunction of the muscle has been implicated in many diseases such as high blood pressure, asthma, and overactive bladders. This is the only book-length treatment of functional models of a variety of smooth muscle behaviors with their corresponding mathematical descriptions, and offers an easy-to-follow, step-by-step mathematical derivation that will help students to appreciate the muscle cell as a fine-tuned aggregate of mechanisms governed by the fundamental laws of physics. In addition to providing a detailed description of the known subcellular structure and mechanical function of the contractile apparatus of smooth muscle, it also covers experimentation techniques, instrumentation, and data analysis. The book is a must-have information source for anyone interested in smooth muscle cell ultrastructure, physiology, biochemistry, and pharmacology.

Download or read book Colonic Motility written by Sushil K. Sarna and published by Biota Publishing. This book was released on 2010-11-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three distinct types of contractions perform colonic motility functions. Rhythmic phasic contractions (RPCs) cause slow net distal propulsion with extensive mixing/turning over. Infrequently occurring giant migrating contractions (GMCs) produce mass movements. Tonic contractions aid RPCs in their motor function. The spatiotemporal patterns of these contractions differ markedly. The amplitude and distance of propagation of a GMC are several-fold larger than those of an RPC. The enteric neurons and smooth muscle cells are the core regulators of all three types of contractions. The regulation of contractions by these mechanisms is modifiable by extrinsic factors: CNS, autonomic neurons, hormones, inflammatory mediators, and stress mediators. Only the GMCs produce descending inhibition, which accommodates the large bolus being propelled without increasing muscle tone. The strong compression of the colon wall generates afferent signals that are below nociceptive threshold in healthy subjects. However, these signals become nociceptive; if the amplitudes of GMCs increase, afferent nerves become hypersensitive, or descending inhibition is impaired. The GMCs also provide the force for rapid propulsion of feces and descending inhibition to relax the internal anal sphincter during defecation. The dysregulation of GMCs is a major factor in colonic motility disorders: irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diverticular disease (DD). Frequent mass movements by GMCs cause diarrhea in diarrhea predominant IBS, IBD, and DD, while a decrease in the frequency of GMCs causes constipation. The GMCs generate the afferent signals for intermittent short-lived episodes of abdominal cramping in these disorders. Epigenetic dysregulation due to adverse events in early life is one of the major factors in generating the symptoms of IBS in adulthood.

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.
