Download and read online ebook Oxidative Stress in Heart Diseases write by Sajal Chakraborti. This book was released on 2019-11-06. Oxidative Stress in Heart Diseases available in PDF, EPUB and Kindle. This book bridges the gap between fundamental and translational research in the area of heart disease. It describes a multidisciplinary approach, and demonstrates biochemical mechanisms associated with dysregulation of redox signaling, which leads heart disease. 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 and read online ebook Modulation of Oxidative Stress in Heart Disease write by Sajal Chakraborti. This book was released on 2019-11-10. Modulation of Oxidative Stress in Heart Disease available in PDF, EPUB and Kindle. 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.

Oxidative Stress and Vascular Disease available in PDF, EPUB and Kindle. 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.

Reactive Oxygen Species and the Cardiovascular System available in PDF, EPUB and Kindle. 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 and read online ebook Studies on Cardiovascular Disorders write by Heinrich Sauer. This book was released on 2010-09-11. Studies on Cardiovascular Disorders available in PDF, EPUB and Kindle. 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.
