Following many years when a great deal of attention was directed towards the intracellular roles of purines, there is expanding interest in the field of extracellular purinergic signalling. In this book we focus on the actions of purines in cardiovascular biology, where it is clear that they play major roles in both normal and pathophysiological conditions. Activation of different purinoceptor subtypes by purines can regulate cardiac contractility and electrical activity, modulate catecholamine-mediated responses both pre- and post-junctionally, trigger and mediate ischaemic preconditioning, cause vasodilation and vasoconstriction and enhance endothelial proliferation and apoptosis as well a...
Cardiac catheterization has long been a central diagnostic modality in the evaluation of children, adolescents, and adults with congenital heart disease, and in children with acquired heart disease. Over the past two decades, transcatheter interventions have become equally important in the treatment of pediatric and congenital heart disease. Some transcatheter therapies have become established as the standard of care for congenital cardiovascular anomalies previously managed surgically, others serve to supplement surgery in the integrated management of complex lesions, and still others are in their infancy, as pediatric interventional cardiology continues to advance in step with the broader ...
This book presents a remarkable collection of chapters that cover a wide range of topics in the areas of information and communication technologies and their real-world applications. It gathers the Proceedings of the Future of Information and Communication Conference 2019 (FICC 2019), held in San Francisco, USA from March 14 to 15, 2019. The conference attracted a total of 462 submissions from pioneering researchers, scientists, industrial engineers, and students from all around the world. Following a double-blind peer review process, 160 submissions (including 15 poster papers) were ultimately selected for inclusion in these proceedings. The papers highlight relevant trends in, and the late...
One of the major biomedical triumphs of the post-World War II era was the defmitive demonstration that hypercholesterolemia is a key causative factor in atherosclerosis; that hypercholesterolemia can be effectively treated; and that treatment significantly reduces not only coronary disease mortality but also all cause mortality. Treatment to lower plasma levels of cholesterol - primarily low density lipoprotein (LDL) cholesterol - is now accepted as best medical practice and both physicians and patients are being educated to take aggressive measures to lower LDL. We can confidently look forward to important decreases in the toll of coronary artery disease over the coming decades. However, th...
The publication embodied here represents the life work of a premier Russian scientist studying Sudden Cardiac Death. As one can gather from more than 35 first authored publications cited in the References, Dr. Rajskina has been involved with the investigation of mechanisms responsible for Sudden Cardiac Death for over 30 years. She has brought a classical approach to the sub ject, considering the effects of blood supply disturbances, electrophysiological changes that occur after regional ischemia, metabolic alterations, and the role of the autonomic nervous system in modulating these changes. These studies naturally lead to a consideration of interventions, based on her research, to prevent ...
The molecular basis for atrial fibrillation continues to be largely unknown, and therapy remains unchanged, aimed at controlling the heart rate and preventing systemic emboli with anticoagulation. Familial atrial fibrillation is more common than previously suspected. While atrial fibrillation is commonly associated with acquired heart disease, a significant proportion of individuals have early onset without other forms of heart disease, referred to as "lone" atrial fibrillators. It is also well recognized that atrial fibrillation occurs on a reversible or functional basis, without associated structural heart disease, such as with hyperthyroidism or of atrial fibrillation following surgery. I...
Although clinicians have recognized the importance of inflammatory mediators in the pathogenesis of heart disease for well over 200 years, it has taken nearly as many years for clinicians and scientists to focus on the basic biological mechanisms by which inflammatory mediators contribute to the pathogenesis of cardiac disease states. Over the past decade there has been increasing interest in the potential role that inflammatory mediators, play in a variety of cardiac disease states, including chronic heart failure. The Role of Inflammatory Mediators in the Failing Heart provides a state-of-the-art review on inflammatory mediators and the failing heart. This book will serve both as a useful introduction to the field, as well as an update for those interested in the role of inflammatory mediators and the failing heart.
This book, with its 16 chapters, documents the present state of knowledge of the adenosine A receptor. It covers a wide range of information, including data from 3 studies of theoretical, molecular and cellular pharmacology, signal transduction, integrative physiology, new drug discoveries and clinical applications. It fills an important gap in the literature since no alternative source of such information is currently available. Although the A receptor is increasingly being recognized for 3 its increasing number of biological roles throughout the body and many A receptor 3 ligands have proven useful in elucidating peripheral and central pathologies, many issues remain unresolved. Moreover, ...
