Singlet Oxygen, the lowest electronically excited state of molecular oxygen, is highly reactive and involved in many chemical and biological processes. It is one major mediator during photosensitization, which has been used by mankind since ancient times, even though the mechanisms behind it were understood only about half a century ago. The combination of high reactivity and very long natural lifetime allows for direct optical detection of singlet oxygen and its interactions using its characteristic phosphorescence at around 1270 nm. Since this emission is very weak, optical detection was technically very challenging for a long time. Therefore, even today, most laboratories only exploit the high reactivity to observe the interaction with sensor molecules, rather than singlet oxygen emission itself. However, in recent years highly sensitive optical detection was developed, the authors being major contributors. This book is dedicated to the detection of singlet oxygen, discussing possibilities, pitfalls and limits of the various methods with a special focus on time-resolved phosphorescence and the kinetics of singlet oxygen generation and decay including involved and related processes, discussing investigated systems with various complexity from solutions over in vitro to in vivo. The long-standing paradigm that singlet oxygen phosphorescence is a benchmark for detection systems rather than an option for process observation is still ubiquitous and this book hopes to contribute in overcoming this still prevailing bias.

Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress.The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes.This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.
This volume addresses oxidant-reduction or redox and antioxidant sensitive molecular mechanisms and how they are implicated in different disease processes. Possible strategies to pharmacologically and/or nutritionally manipulate such redox-sensitive molecular responses are emphasized. - Reactive species as intracellular messengers - Redox regulation of cellular responses - Clinical implications of redox signaling and antioxidant therapy
The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.
Significant progress has been made in recent years in quenched-phosphorescence oxygen sensing, particularly in the materials and applications of this detection technology that are open to commercialization, like uses in brain imaging and food packaging. Prompted by this, the editors have delivered a dedicated book that brings together these developments, provides a comprehensive overview of the different detection methodologies, and representative examples and applications. This book is intended to attract new researchers from various disciplines such as chemistry, physics, biology and medicine, stimulate further progress in the field and assist in developing new applications. Providing a concise summary at the cutting edge, this practical guide for current experts and new potential users will increase awareness of this versatile sensing technology.
Free Radicals in Biology, Volume II is a nine-chapter text that describes the complexities in the chemical and physical behavior of free radicals. After briefly providing an overview of the biology of pyridinyl radicals, this book goes on discussing the role of glutathione in the cell and the reactions of single oxygen and its role in photochemical smog and in cellular chemistry. These topics are followed by a discussion on the production of free radicals from dry tissue. The subsequent chapters describe some of the key reactions in photochemical smog, including reaction studies by computer simulation, as well as the specific reactive materials that are present in smog. These chapters also look into the chemistry of nitrogen oxides and ozone, which are some of the most important reactions in photochemical smog. The concluding chapters explore the radiation damage to proteins and radiation protection and radical reactions produced by radiation in nucleic acids. Chemists, biologists, and physicists will find this text invaluable.
