This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consistent with the occurrence of arrhythmias in junctin-deficient mice, 50% of them died sporadically up to 17 months of age, while none of the heterozygous mice died up to that time. Thus, normal intracellular Ca-cycling relies on maintenance of junctin levels and an intricate balance among the components in the SR quaternary Ca-signaling complex.

Download or read book Excitation Contraction Coupling and Cardiac Contractile Force written by Donald Bers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: How is the heartbeat generated? What controls the strength of contraction of heart muscle? What are the links between cardiac structure and function? How does our understanding of skeletal and smooth muscle and non-muscle cells influence our thinking about force development in the heart? Are there important species differences in how contraction is regulated in the heart? How do the new molecular data fit together in understanding the heart beat? What goes wrong in ischemia, hypertrophy, and heart failure? This book paints a modern `portrait' of how the heart works and in this picture the author shows a close-up of the structural, biochemical, and physiological links between excitation and contraction. The author takes the reader through a series of important, interrelated topics with great clarity and continuity and also includes many useful illustrations and tables. The book starts by considering the cellular structures involved in excitation-contraction coupling and then described the characteristics of the myofilaments as the end effector of excitation-contraction coupling. A general scheme of calcium regulation is described and the possible sources and sinks of calcium are discussed in simple, but quantitative terms. The cardiac action potential and its many underlying currents are reviewed. Then the characteristics of some key calcium transport systems (calcium channels, sodium/calcium exchange and SR calcium uptake and release) are discussed in detail. This is then built into a more integrated picture of calcium regulation in succeeding chapters by detailed discussions of excitation-calcium coupling mechanisms (in skeletal, cardiac, and smooth muscle), the interplay between calcium regulatory processes, and finally mechanisms of cardiac inotropy, calcium overload, and dysfunction (e.g., ischemia, hypertrophy, and heart failure). Excitation-Contraction Coupling and Cardiac Contractile Force – Second Edition is an invaluable source of information for anyone who is interested in how the heart beat is controlled and especially suited for students of the cardiovascular system at all levels from medical/graduate students through senior investigators in related fields.

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.

Download or read book The Role of Calcium Handling in Heart Failure and Heart Failure Associated Arrhythmias written by Elisabetta Cerbai and published by Frontiers Media SA. This book was released on 2019-05-15 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under normal, healthy conditions, the contraction of cardiac myocytes, leading to the pump function of this organ, is driven by calcium-dependent mechanisms. Entry of calcium into the myocyte during the cardiac action potential causes activation of the ryanodine receptors and release of calcium from the sarcoplasmic reticulum. This process termed calcium-induced calcium release is essential for excitation-contraction coupling and enables each action potential to be transduced into a mechanical event. Indeed, in healthy myocytes, the calcium concentration in the cytosol of is elevated approximately 10-fold from a resting level of ∼100 nM to ∼1 μM. This process is finely orchestrated by a number of key proteins, which can be specifically regulated by various pathways depending on the oxygen demand. Furthermore, the specific structure of the myocyte allows certain calcium-dependent processes to be compartmentalised, increasing the efficiency and safety of this regulation. Heart failure is a common, costly, and life-threatening condition. In 2015, for example, it affected around 40 million people globally. In patients with heart failure, the risk of sudden cardiac death and arrhythmias increases substantially. Cellular remodelling and alterations in calcium handling, which appear to contribute to the arrhythmogenic burden in heart failure, have been extensively reported. However, a number of unanswered questions remain, and each new study - while continuing to shed light on this subject - raises additional novel questions. This current compendium of articles covers a number of aspects and comprehensively reviews current knowledge and perspectives regarding the link between calcium handling, arrhythmias and heart failure providing at the same time insights that may lead to novel therapeutic options for the future.
