This book was released on 2012-12-06 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 Oxidative Stress Revisited Major Role in Vascular Diseases written by Cristina M. Sena and published by Frontiers Media SA. This book was released on 2019-10-21 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress is an underlying factor in health and disease. Reactive oxygen species are produced as a result of normal cellular metabolism. The subsequent altered redox state between the formation and the neutralization of pro-oxidants results in their increased levels and therefore leads to cellular damage. Different research disciplines have increased our knowledge of the importance of this cell redox status and the recognition of oxidative stress as a process with implications for many pathophysiological states. Genetic and environmental factors, nutrition and lifestyle may indicate a pro-oxidative and pro-inflammatory state, linked to alterations in cellular structure and function. Oxidative stress emerges as a common, unifying factor in several conditions including diabetes and cardiovascular diseases. This eBook aims to provide novel data regarding the role played by oxidative stress and inflammation in the development of chronic diseases and the different classes of therapeutics from the bench to the clinic, stressing the awareness of these concepts for the treatment of disease. In addition, articles addressing an overview of the role of oxidative stress in vascular diseases reviewing some current concepts indicating that oxidative stress and inflammation are key mechanisms linking vascular diseases and current state-of-the-art approaches to monitor, prevent and inhibit oxidative stress will be highlighted. There is a close relation between oxidative stress, inflammation and cardiovascular diseases. Despite the great amount of investigation carried out in the field, there are still uncertainties about the mechanisms by which free radicals can modify tissues such as perivascular adipose tissue that ultimately will reflect on vascular function. This eBook will focus on articles that can explore and identify these mechanisms. Concurrent with this understanding of oxidative stress milieu, it is necessary to recognize the need for new pharmacological tools effective in restoring oxidative balance. The abundance of new information and the paradigm shift in our understanding of how antioxidants and other redox-active drugs work in a wide variety of vascular diseases will be specifically highlighted. This eBook will provide a comprehensive, up-to-date source of information on the design and mechanistic, pharmacological, and medicinal aspects of redox-active therapeutics. Finally, a unique feature of the eBook is to provide a way to foster an enthralling discussion revisiting old paradigms and finding new solutions for the treatment of vascular diseases. The topic will include original research articles, hypotheses, perspectives and (mini)reviews from experts in the field. The next decade shows promise for the translation of this body of knowledge to novel human therapeutics and this eBook will enable to increment our knowledge in this field.

Download or read book Reactive Oxygen Species and the Cardiovascular System written by Augusto C. Montezano and published by Morgan & Claypool Publishers. 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.

Download or read book Oxidative Stress Inflammation and Atherosclerosis Related Diseases From basic to clinical research written by Qiang Liu and published by Frontiers Media SA. This book was released on 2023-11-27 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. As a result, different diseases (ischemic heart disease, carotid artery disease, peripheral artery disease, ischemic stroke, and chronic kidney disease) may develop based on which arteries are affected. Atherosclerosis-related diseases are a global crisis and require a global response. The increasing global crisis in atherosclerosis-related diseases is a barrier to development goals including poverty reduction, health equity, economic stability, and human security. There is a synergic action between genetic, ambient, local, and systemic factors, and ultimately the progression of atherosclerosis is responsible for coronary heart disease (CHD) and its complications (such as unstable “in crescendo” angina, myocardial infarction, and sudden death), peripheral arterial disease, and ischemic stroke. Recent investigations show that mitochondrial alterations, oxidative stress and inflammation are inextricably linked and play major roles in the onset and development of atherosclerosis-related diseases. Long-term oxidative stress, autophagy and vascular inflammation could lead to atherosclerosis-related diseases. The evidence of oxidative stress, inflammation, autophagy, mitochondrial dynamic dysfunction, and the interaction of those factors had been proposed.

Download or read book Antioxidants and Cardiovascular Disease written by J.C. Tardif and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Generation of oxidants or reactive oxygen species is a natural process of human biology. Mitochondrial respiration, phagocytic activity and cyclooxygenase activation are all essential processes of life, which also generate oxidative species. In humans, chronic oxidative stress often coupled with deficiency of antioxidant defenses is associated with the aging process and can lead to the development of disorders such as cancer and arterial disease. Major cardiovascular conditions in which oxidative damage has been strongly implicated include atherosclerosis, myocardial ischemia and reperfusion, coronary restenosis and congestive heart failure. Compelling evidence points to oxidative stress as an important trigger in the complex chain of events leading to atherosclerosis. The expression of chemotactic factors and adhesion molecules is modified by oxidative stress. Exposure to superoxide ions activates the NF-kappa B regulatory complex and triggers the transcription of several atherosclerosis related genes. These events lead to the accumulation of macrophages in the arterial wall. Macrophages avidly incorporate oxidized low-density lipoproteins (LDL) to form foam cells. The activity of matrix metalloproteinases is also regulated by oxidative stress. This activity appears to be closely coupled with smooth muscle cell activation and migration. Matrix metalloproteinases have also been implicated in the pathophysiology of plaque rupture. Antioxidant supplementation including vitamin E decreases susceptibility ofLDL to oxidation and retards the progression of atherosclerosis in animal models.

Download or read book Smoking Prevention and Cessation written by Mirjana Rajer and published by BoD – Books on Demand. This book was released on 2018-12-05 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smoking was and remains one of the most important public healthcare issues. It is estimated that every year six million people die as a result of tobacco consumption. Several diseases are caused or worsened by smoking: different cancer types, heart disease, stroke, lung diseases and others. In this book we describe the different toxic effects of smoke on the human body in active and in passive smokers. It is also well known that many people who smoke wish to quit, but they rarely succeed. Smoking prevention and cessation are of utmost importance, thus we also describe different strategies and aspects of these issues. We hope that this book will help readers to understand better the effects of smoking and learn about new ideas on how to effectively help other people to stop smoking.

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to clarify the potential association between frailty and cardiovascular disease in older people. Covering the biological as well as the clinical point of view, it allows researchers and clinicians to discover the significance of this topic. The contributions cover the most important aspects in the potential relationship between frailty and cardiovascular disease. In particular, authoritative authors in this field have clarified the definition and the epidemiology of frailty and cardiovascular disease in older people. A large part of the volume is dedicated to the biological mechanisms of frailty and cardiovascular disease, trying to find those in common between these two conditions. Since this book is dedicated to both researchers and clinicians, we have proposed some chapters to the importance of comprehensive geriatric assessment in the evaluation and treatment of cardiovascular diseases and frailty. In this regard, the importance of geriatric evaluation in cardiac surgery for older people is well covered. Finally, the importance of cardiac rehabilitation and physical exercise is summarized, being, actually, the most important treatments for both frailty and cardiovascular disease. Written by many well-known and widely published experts in their respective fields, this book will appeal to a wide readership such as researchers in the field and clinicians, especially suited in geriatric medicine and cardiology who, every day, face frail older patients.

Download or read book Studies on Cardiovascular Disorders written by Heinrich Sauer and published by Humana Press. This book was released on 2012-11-07 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of reactive oxygen species (ROS) in the cardiovascular system is Jan- faced. Whereas low concentrations of ROS are involved in variety of physiological signalling events, oxidative stress resulting from deregulated overproduction of ROS and/or impaired antioxidant defences contributes to cardiovascular disease. The actions of ROS in the cardiovascular system are a fascinating topic, not only for the basic science researcher but also for the clinician who is interested in seeking new therapies for his patients suffering from cardiovascular disease. The current book provides a comprehensive overview of the molecular mechanisms and pathoph- iological settings in which chronic and detrimental oxidative stress arises within the heart and vasculature. The book also considers currently discussed strategies in avoiding chronic redox stress resulting from exposure to risk factors or various cardiovascular interventions. The series starts with an overview by Denise de Castro Fernandes, Diego Bonatto and Francisco Laurindo of redox signaling models that could underlie the dev- opment of redox-associated cardiovascular disorders. The interactions of proteins within signalling cascades with ROS and the regulation of such interactions by the anti-oxidative capacity of the cell are discussed. Rebecca Charles, Joseph Burgoyne and Philip Eaton report on redox-mediated modi cations of proteins under ph- iological and pathophysiological conditions and the variety of post-translational oxidative modi cations that explain redox sensing and signal transduction by proteins at the molecular level. ROS are generated during embryogenesis and may be involved in the proper development of the cardiovascular system.
