Download or read book Integrative Computational Modeling of Calcium Handling and Cardiac Arrhythmias written by Henry Sutanto and published by Henry Sutanto. This book was released on 2021-01-01 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiomyocyte calcium handling is a major determinant of excitation-contraction coupling. Alterations in one or more calcium-handling proteins may induce arrhythmias through the formation of ectopic activity, direct and indirect ion-channel regulation, and structural remodeling. Due to the complex and tight interactions between calcium and other molecules within a cardiomyocyte, it remains experimentally challenging to study the exact contributions of calcium-handling abnormalities to arrhythmogenesis. Multiscale computational studies performed in close collaboration with laboratory experiments create new opportunities to unravel the mechanisms of arrhythmogenesis. This thesis describes the roles of integrative computational modeling in unraveling the arrhythmogenic consequences of calcium-handling abnormalities.

Download or read book Cardiovascular Physiology in the Genetically Engineered Mouse written by Brian D. Hoit and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enormous advances in molecular biology and genetics coupled with the progress in instrumentation and surgical techniques have produced a voluminous and often bewildering quantity of data. The need for a second edition of Cardiovascular Physiology in the Genetically Engineered Mouse is underscored not only by these rapid advances, but by the increasing numbers of scientists who have focussed their research on genetically engineered mice. It is the primary objective of this second edition to interpret critically the literature and to provide a framework for the enormous amount of information in this burgeoning field. As in the first edition, the monograph serves as a practical guide for the investigator interested in the functional methods used to characterize the murine cardiovascular phenotype. However, this guidebook is a more comprehensive text than its predecessor; although the major objectives enumerated in the first edition have not substantially changed, they have been refined in keeping with the increased sophistication of the molecular biologist, geneticist, and physiologist in each other's discipline. Each chapter has been expanded and updated, richly enhanced with original tables and figures, and in many cases, extensively rewritten. Eight chapters written by internationally recognized experts have been added; this represents a 43 % increase from the first edition.

Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.
Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.
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.

Download or read book The Role of Mitochondria Oxidative Stress and Altered Calcium Homeostasis in Amyotrophic Lateral Sclerosis From Current Developments in the Laboratory to Clinical Treatments written by Manoj Kumar Jaiswal and published by Frontiers Media SA. This book was released on 2017-04-17 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive, devastating and fatal disease characterized by selective loss of upper and lower motor neurons of the cerebral cortex, brainstem, spinal cord and muscle atrophy. In spite of many years of research, the pathogenesis of ALS is still not well understood. ALS is a multifaceted genetic disease, in which genetic susceptibility to motor neuron death interacts with environmental factors and there is still no cure for this deleterious disease. At present, there is only one FDA approved drug, Riluzole which according to past studies only modestly slows the progression of the disease, and improves survival by up to three months. The suffering of the ALS patients, and their families is enormous and the economic burden is colossal. There is therefore a pressing need for new therapies. Different molecular pathways and pathological mechanisms have been implicated in ALS. According to past studies, altered calcium homeostasis, abnormal mitochondrial function, protein misfolding, axonal transport defects, excessive production of extracellular superoxide radicals, glutamate-mediated excitotoxicity, inflammatory events, and activation of oxidative stress pathways within the mitochondria and endoplasmic reticulum can act as major contributor that eventually leads to loss of connection between muscle and nerve ultimately resulting to ALS. However, the detailed molecular and cellular pathophysiological mechanisms and origin and temporal progression of the disease still remained elusive. Ongoing research and future advances will likely advance our improve understanding about various involved pathological mechanism ultimately leading to discoveries of new therapeutic cures. Importantly, clinical biomarkers of disease onset and progression are thus also urgently needed to support the development of the new therapeutic agents and novel preventive and curative strategies. Effective translation from pre-clinical to clinical studies will further require extensive knowledge regarding drug activity, bioavailability and efficacy in both the pre-clinical and clinical setting, and proof of biological activity in the target tissue. During the last decades, the development of new therapeutic molecules, advance neuroimaging tools, patient derived induced stem cells and new precision medicine approaches to study ALS has significantly improved our understanding of disease. In particular, new genetic tools, neuroimaging methods, cellular probes, biomarker study and molecular techniques that achieve high spatiotemporal resolution have revealed new details about the disease onset and its progression. In our effort to provide the interested reader, clinician and researchers a comprehensive summaries and new findings in this field of ALS research, hereby we have created this electronic book which comprises of twenty seven chapters having various reviews, perspective and original research articles. All these chapters and articles in this book not only summarize the cutting-edge techniques, approaches, cell and animal models to study ALS but also provide unprecedented coverage of the current developments and new hypothesis emerging in ALS research. Some examples are novel genetic and cell culture based models, mitochondria-mediated therapy, oxidative stress and ROS mechanism, development of stem cells and mechanism-based therapies as well as novel biomarkers for designing and testing effective therapeutic strategies that can benefit ALS patients who are at the earlier stages in the disease. I am extremely grateful to all the contributors to this book and want to thank them for their phenomenal efforts. Manoj Kumar Jaiswal, Ph.D. February 5, 2017 New York, NY

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 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.

Download or read book Calcium Entry Channels in Non Excitable Cells written by Juliusz Ashot Kozak and published by CRC Press. This book was released on 2017-07-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.
