Book Description
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.

Book Description
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.

Book Description
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.

Book Description
In patients surviving a myocardial infarction M), the heart undergoes a remodefing process characterized by hypertrophy which can also lead to heart failure. Although hypertrophy is an early response that may temporarily preserve cardiac function, numerous studies have suggested that this long term process of remodefing is also associated with an increase in oxidative stress and cardiac decompensation. The objectives of the present research on rat hearts subsequent to MI therefore, were to: (i) characterize changes in the oxidative stress and enzymatic antioxidants, (superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and catalase) in relation to their rnRNA abundance and protein content; (ii) study changes in nonenzymatic antioxidants at different stages of heart failure in relation to cardiac function in order to have a more comprehensive information about the antioxidant reserve, and (iii) study the effects of RAS inhibition at the AT1 receptor site by losartan on the myocardial enzymatic and non-enzymatic antioxidants (SOD, GSHPx, catalase, vitamins A and E) and oxidative stress (Lipid hydroperoxides, reduced and oxidized glutathione and the redox ratio) in relation to the changes in hemodynamic function during the sequelae of congestive heart failure. It is concluded that inhibition of the RAS at the AT1 receptor site with losartan, in addition to reducing cardiac remodeling and improving hemodynamic function, reduces oxidative stress and improves myocardial endogenous antioxidants subsequent to myocardial infarction. The study suggests a newer role for losartan in the treatment of heart failure. Although changes in the SOD and catalase activities during heart failure correlated with changes in mRNA for these enzymes, the precise mechanism/s for decrease in oxidative, stress and improvement in antioxidant reserve after losartan treatment is/are unclear at this time.

Book Description
This book discusses recent advances in our understanding of the role of oxidants in microbial pathophysiology, providing valuable insights into the complex role of reactive oxygen species (ROS) in host-microbial interactions. The various chapters take readers through the function of ROS in infections ranging from viral to bacterial, and describe how microorganisms have developed complex strategies to not only avoid contact with phagocyte-derived oxidants, but also protect themselves from injury when oxidants are encountered. Featuring the latest research in the field of microbial diseases, this timely book is a ready reference for scientists looking to develop new anti-microbial drugs.

Book Description
The book starts with the editors' preface summarizing the contributions of each of the following thirteen articles dealing with chemical and pharmacological aspects of the molecular modulators of the oxidative stress in regard to various therapeutic approaches in cardiovascular and neurodegenerative diseases, cancer, and diabetes. The seven articles present data from original research studies enlightening the roles and mechanisms of action of small molecular weight compounds (natural and synthetic; ascorbic acid/vitamin C, deferoxamine, N-acetylcysteine, MitoVitE, α-tocopherol, trolox, and ezetimibe) or proteins (SIRT3) in modulation of oxidative stress. In the six review papers, the authors present and discuss the possible therapeutic potential of novel approaches and compounds that are promising and deserve further investigation, in modulation of oxidative stress.

Book Description
This volume includes contributions by the leading experts in the field of yeast aging. Budding yeast (Saccharomyces cerevisiae) and other fungal organisms provide models for aging research that are relevant to organismic aging and to the aging processes occurring in the human body. Replicative aging, in which only the mother cell ages while the daughter cell resets the clock to zero is a model for the aging of stem cell populations in humans, while chronological aging (measured by survival in stationary phase) is a model for the aging processes in postmitotic cells (for instance, neurons of the brain). Most mechanisms of aging are studied in yeast. Among them, this book discusses: mitochondrial theories of aging, emphasizing oxidative stress and retrograde responses; the role of autophagy and mitophagy; the relationship of apoptosis to aging processes; the role of asymmetric segregation of damage in replicative aging; the role of replication stress; and the role of the cytoskeleton in aging. Modern methods of yeast genetics and genomics are described that can be used to search for aging-specific functions in a genome-wide unbiased fashion. The similarities in the pathology of senescence (studied in yeast) and of cancer cells, including genome instability, are examined.
