This book was released on 2012 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive oxygen species (ROS) influence various physiological processes including host defense, hormone biosynthesis, and cellular signaling. Increased ROS production (oxidative stress) is implicated in many diseases of the cardiovascular system, including hypertension, atherosclerosis, cardiac failure, stroke, diabetes, and kidney disease. ROS are produced throughout the cardiovascular system, in the kidney and central and peripheral nervous system. A major source for cardiovascular, renal, and neural ROS is a family of non-phagocytic NAD(P)H oxidases, including the prototypic Nox2 homologue-based NAD(P)H oxidase, as well as other NAD(P)H oxidases, such as Nox1 and Nox4. Other possible sources include mitochondrial electron transport enzymes, xanthine oxidase, cyclooxygenase, lipoxygenase, and uncoupled nitric oxide synthase (NOS). NAD(P)H oxidase-derived ROS is important in regulating endothelial function and vascular tone and oxidative stress is implicated in endothelial dysfunction, inflammation, hypertrophy, apoptosis, migration, fibrosis, angiogenesis and rarefaction, important processes involved in vascular remodeling in cardiovascular disease. These findings have evoked considerable interest because of the possibilities that therapies targeted against non-phagocytic NAD(P)H oxidase to decrease ROS generation and/or strategies to increase nitric oxide (NO) availability and antioxidants may be useful in minimizing vascular injury and thereby prevent or regress target organ damage associated with hypertension and other cardiovascular diseases.

This book was released on 2019-01-22 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of ROS/RNS signaling in cardiovascular functions and diseases is increasingly emerging in the last decades. The involvement of ROS/RNS in the control of a large number of cardiovascular functions like the regulation of the vascular tone, the control of blood pressure or myocyte excitation-contraction coupling and force development has been broadly investigated and in part clarified. On the other hand, many efforts have been focused in clarifying the redox mechanisms involved in cardiovascular diseases like ischemia/reperfusion injury, diabetes-associated cardiovascular dysfunctions, atherosclerosis or hypertension, just to mention the major ones. However, in most cases the two levels of investigation remain separate and not interlaced, failing in the attempt to provide a unified vision of the pathophysiologic mechanisms of cardiovascular diseases. The major aim of the Research Topic has been to collect original papers and review articles dealing with the issue from basic to translation research point of views. The topic includes contributions that highlight different interesting aspects of cardiovascular biology with an integrated approach useful for the development of new ideas and advancements in the field of redox signaling in the control of normal cardiovascular functions and their disruption in diseases.

Presenting recent studies on improved forms of ROS scavenging enzymes; specific inhibitors for different ROS generating enzymes; and oxidant induced signaling pathways and their antagonists that allow subtle modulation of redox signaling, it also discusses the spatial and temporal aspects of oxidative stress in the cardiovascular system, which are of vital importance in developing better strategies for treating heart disease. Each chapter offers researchers valuable insights into identifying targets for drug development for different types of heart disease.
Download or read book Modulation of Oxidative Stress in Heart Disease written by Sajal Chakraborti and published by Springer Nature. This book was released on 2019-11-10 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the multifaceted roles of Reactive Oxygen Species (ROS) in modulating normal cellular and molecular mechanisms during the development of different types of heart disease. Each chapter in the book deals with the role that altered redox homeostasis plays in the pathophysiology of heart disease. In addition, the book explains how reactive oxidant species interact with their targets and provides novel strategies for attenuating oxidative stress-induced types of heart disease. The book not only covers ROS-induced response in heart disease at the cellular level, but also demonstrates that an imbalance of redox states has its roots in our genes, and explains the ways gene expression is regulated. In turn, it reviews potential sources of ROS, their pathological effects on the heart, and potential sites for therapeutic interventions.

Download or read book Oxidative Stress and Vascular Disease written by John F. Keaney Jr. and published by Springer Science & Business Media. This book was released on 1999-12-31 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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, there is still uncertainty as to the exact mechanisms by which elevated plasma cholesterol and LDL levels initiate and favor the progression of lesions. There is general consensus that one of the earliest responses to hypercholesterolemia is the adhesion of monocytes to aortic endothelial cells followed by their penetration into the subendothelial space, where they differentiate into macrophages. These cells, and also medial smooth muscle cells that have migrated into the subendothelial space, then become loaded with mUltiple, large droplets of cholesterol esters . . . the hallmark of the earliest visible atherosclerotic lesion, the so-called fatty streak. This lesion is the precursor of the more advanced lesions, both in animal models and in humans. Thus the centrality of hypercholesterolemia cannot be overstated. Still, the atherogenic process is complex and evolves over a long period of time.
Download or read book Reactive Oxygen Species ROS in Living Cells written by Filip Cristiana and published by BoD – Books on Demand. This book was released on 2018-05-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen represents only 20% of the Earth's atmosphere, yet it is vital for the survival of aerobic organisms. There is a dark part of the use of oxygen that consists in generating reactive species that are potentially harmful to living organisms. Moreover, reactive oxygen species can combine with nitrogen derivatives and generate many other reactive species. Thus, living organisms are continuously assaulted by reactive species from external or internal sources. However, the real danger comes in the case of high concentrations and prolonged exposure to these species. This book presents an image of the mechanisms of action of reactive species and emphasizes their involvement in diseases. Inflammation and cancer are examined to determine when and how reactive species turn the evolution of a benign process to a malignant one. Some answers may come from recent studies indicating that reactive species are responsible for epigenetic changes.

This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over two centuries ago, oxygen was discovered as "air vital": the component of the earth's atmosphere necessary for life. Less than five years after this discovery, it was found that oxygen was both a life-sustaining and life threatening inhalant as it plays a role in the two extremes of the animal kingdom: life and death. In the subse quent years, we have made major strides in understanding the role of oxygen in maintaining life and volumes of information are now available on this topic. Our knowledge of the contribution of oxygen in cellular dysfunction and cell death which for the most part had lagged behind has begun to catch up. The deleterious ef fects of oxygen radicals and activated oxygen species on a variety of biological systems have now been described. Recently attention has also been focused on the toxic effects of oxygen on the cardiovascular system. The major aim of the present treatise is to offer an integrated view of the pathophysiological aspects of oxygen toxicity in the heart and blood vessels coupled with a review of therapeutic approaches (hopes?) with free radical scavengers and antioxidants. Internationally known expert investigators provide a concise and critical review on the topic of their expertise which also contains data from their own research.

Download or read book Studies on Cardiovascular Disorders written by Heinrich Sauer and published by Springer Science & Business Media. This book was released on 2010-09-11 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of articles on oxidative stress in clinical practice surveys essential current research in what is a rapidly evolving field. As well as giving the reader a mechanistic overview of how oxidative stress affects cardiovascular disease, it analyzes the potential of a number of therapeutic options that target these pathways. Understanding the complexity of the cellular redox system could lead to the development of better targeted interventions that facilitate patient recovery. Even as large-scale clinical trials of so-called ‘simple’ antioxidant approaches such as vitamins C and E show that significant benefits for cardiovascular patients remain elusive, Studies on Cardiovascular Disorders demonstrates that such approaches are too simplistic. Beginning with a summary of redox signaling models that could induce the progression of redox-associated cardiovascular disorders, the volume moves on to examine redox-mediated protein modification under physiological and pathophysiological conditions. It provides an outline of the signaling pathways in cardiovascular development during embryogenesis, and what impact these might have in the differentiation process of resident cardiac and blastocyst derived stem cells. Further chapters detail our current knowledge of the influence the sensory nervous system exerts on the cardiovascular system, and the paradoxical role of mitochondria-derived ROS in cardiac protection. In all, almost 30 contributions cover issues as diverse as the antioxidant properties of statins in the heart and the oxidative risk factors for cardiovascular disease in women. A range of medical practitioners will find the contents of Studies on Cardiovascular Disorders provides illuminating insight into the Janus-faced role of ROS in the cardiovascular system.
Download or read book Reactive Oxygen Species written by Harald H. H. W. Schmidt and published by Springer Nature. This book was released on 2021-02-23 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive oxygen species (ROS) have been implicated in almost every human disease phenotype, without much, if any, therapeutic consequence foremost exemplified by the failure of the so-called anti-oxidants. This book is a game changer for the field and many clinical areas such as cardiology and neurology. The term ‘oxidative stress’ is abandoned and replaced with a systems medicine and network pharmacology-based mechanistic approach to disease. The ROS-related drugs discussed here target either ROS- forming or ROS -modifying enzymes for which there is strong clinical evidence. In addition, ROS targets are included as they jointly participate in causal mechanisms of disease. This approach is transforming the ROS field and represents a breakthrough in redox medicine indicating a path to patient benefit. In the coming years more targets and drugs may be discovered, but the approach will remain the same and this book will thus become, and for many years remain, the leading reference for ROSopathies and their treatment by network pharmacology.

Download or read book Reactive Oxygen Species at High Altitude Hypobaric Hypoxia on the Cardiovascular System written by Patricia Siques and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive oxygen species (ROSs) play important physiological and physiopathological roles in the cardiovascular system. An imbalance between ROS and antioxidants, termed oxidative stress, can contribute to endothelial dysfunction and cardiovascular remodeling. ROSs have been demonstrated to be increased and to regulate the following main pulmonary vasculature changes that occur at high altitude (hypobaric hypoxia): hypoxic pulmonary vasoconstriction (HPV), pulmonary hypertension, right ventricular hypertrophy (RVH), and ultimately, cardiac failure. Thus, ROS increases are a public health concern for the increasing number of people living or working at high altitudes. ROSs trigger the activation of different metabolic signaling pathways that alter the activity of redox-sensitive transcription factors and translational signals. Consequently, we provide a comprehensive review of the literature on the main factors, sources, and mechanisms of action of ROS and their effects on the cardiovascular system under hypobaric hypoxic conditions. Although ROS generation is a normal physiological activity, under hypobaric hypoxia (high altitude) conditions, ROS levels are elevated. The principal sources of ROS are nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-4 (NOX4) in the vascular system and NOX2 in cardiac tissue. Thus, the information presented in this review provides a broad view of the relationship between ROS and hypoxia.
