Once the existence of free radicals was proven, an avalanche of studies on free radical-mediated biological processes ensued. The study of reactive oxygen and nitrogen species (ROS and RNS) is center stage in biological free radical investigations. Written by a biochemist, Signaling Mechanisms of Oxygen and Nitrogen Free Radicals discusses the regu

Nitric oxide (NO) has been discovered to play a fundamental role in a number of biological phenomena. This book describes various aspects of nitric oxide biology, physiology and pharmacology. It is divided into three sections. The first part deals with the basic chemistry and enzymology of NO, thus laying a molecular basis for what follows. The middle part surveys the physiological roles of NO under normal conditions. The concluding part explores the relevance of NO to disease, both as a pathogenic factor and a therapeutic target. The book thus provides detailed information on NO biology to the reader unfamiliar with the field and represents a reference work for scientists working in an NO-related field of biomedical research. Each chapter, written by experts in their fields, gives a broad introduction followed by a comprehensive review of the current knowledge and a detailed reference list.

"Provides the latest advances in the explosive growth of nitric oxide (NO) study-covering the behavior of this highly reactive molecule in a wide variety of physiologicial processes, including respiration, blood pressure, neurotransmission, nospecific host defense, and wound healing."

Leading clinical and experimental investigators comprehensively review the chemistry, biochemistry, molecular biology, physiology, and pathophysiology of nitric oxide in the cardiovascular systems. These experts particularly illuminate nitric oxide biology, its cardiovascular pathophysiology, and its role in cardiovascular therapeutics. Topics also included are the development of nitric oxide donors for the treatment of myocardial ischemia and thrombosis, the development of gene therapeutic restoration of endothelial function in atherosclerosis, and the application of nitric oxide biology to investigative arenas in cardiovascular medicine. With its balanced presentation of basic and clinically relevant information, Nitric Oxide and the Cardiovascular System provides a comprehensive, authoritative guide for all those cardiovascular biologists, cardiologists, physiologists, and cardiovascular surgeons engaged in today's clinical or experimental research.

Papers: characterization of inducible nitric oxide synthase expression in human airway epithelium; nitric oxide and its congeners in mitochondria; role of nitric oxide in inflammation and tissue injury during endotoxemia and hemorrhagic shock; nitric oxide and peroxynitrite production in ocular inflammation; 5 papers on pulmonary/pollutant effects; 6 papers on oxidants and signal transduction, including impact of oxidative stress on signal transduction control by phosphotyrosine phosphatases; the nature of antioxidant defense mechanisms; lipid peroxidation products and antioxidants in human disease; and lung injury and oxidoreductases.

Conditions such as oxidative stress and hypoxia, which have a generalized impact on the oxygen metabolism, have been implicated in the genesis of kidney disease. This means that deepening our understanding of the pathobiology of oxygen metabolism in such diseases could be a fruitful path towards tangible clinical benefits. Studies in Renal Disorder collects reviews from leading researchers and clinical scientists working in exactly this field, providing an overview of the latest advances. The causal role of impaired oxygen metabolism in kidney disease has numerous clinical implications. It affects our understanding of the therapeutic benefits accruing from anti-hypertensive agents; the way we control hyperglycemia/hyperinsulinemia and hyperlipidemia; and our use of dietary approaches to the correction of obesity. The defensive mechanisms against oxidative stress, such as the Nrf2-Keap1 system, and hypoxia, such as the PHD-HIF system, have recently been explored in various cells, including kidney cells. These mechanisms include intracellular sensors for oxidative stress and hypoxia. This means that novel approaches targeting these sensors may offer clinical benefits in kidney disease in which oxidative stress and/or hypoxia is a final, common pathway.
