Molecular Mechanisms of Oxygen Activation reviews some of the major advances that have been made in our understanding of the molecular mechanisms underlying oxygen activation, with emphasis on the role of oxygen activation in contemporary biological processes. The biological role of oxygenases in the metabolism of fatty acids and steroids is discussed, along with the functions of heme-containing dioxygenases, a-ketoglutarate-coupled dioxygenases, and pterin-requiring aromatic amino acid hydroxylases. This book is comprised of 14 chapters and begins with an overview of the general properties and biological functions of oxygenases, along with the chemical aspects of oxygen fixation reactions. The reader is then introduced to research concerning fatty acid and steroid oxygenases which has appeared in the literature since 1962, paying particular attention to the mechanism of oxygenation and the biosynthesis and metabolism of steroids. Subsequent chapters explore the biological functions of a variety of oxygenases such as heme-containing dioxygenases, copper-containing oxygenases, flavoprotein oxygenases, and pterin-requiring aromatic amino acid hydroxylases. Superoxide dismutase, cytochrome c oxidase, peroxidase, and bacterial monoxygenases are also considered. This monograph should serve as a valuable reference for biochemists as well as undergraduate and graduate students of biochemistry.

First Published in 1995: Written by specialists in their fields, this book contains short reviews intended to highlight points of growing interest in mechanistic toxicology. The first section considers selected aspects of molecular mechanisms, including selectivity of toxic agents and repair processes in the nervous system, toxicity of oxygen, fibers and aflatoxins. The second section discusses the interactions of carcinogens with DNA, and other targets, and their relevance to both molecular dosimetry of exposure and development of cancer. The final part is concerned with cellular and genetic aspects and includes coverage of some of the most recent and rapidly developing problems in toxicology.

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

This book focuses on hyperbaric oxygenation (HBO) therapy from the molecular biology perspective and its clinical applications, including molecular mechanisms of HBO’s positive effect on cellular function in hypoxic tissues. HBO is a therapeutic tool that enhances oxygen supply to hypoxic tissues and improves wound healing/tissue remodeling. Currently HBO therapy is applied to a wide range of clinical cases, which include not only acute hypoxic diseases but also many chronic and refractory diseases involving tissue hypoxia or intractable infection. HBO therapy is a well-recognized regimen for many researchers and clinicians. The first half of the book outlines basic molecular mechanisms of HBO and their potential applications for clinical activities, while the second half describes the rationale behind introducing HBO therapy into suitable clinical cases and presents successful clinical reports. It is primarily written for HBO clinicians, physiologists and basic research scientists, but is also of interest to clinicians who have an interest in this field considering introducing HBO therapy.
