This book is based on the invited and contributed papers presented at the 2nd International Conference on Anticarcinogenesis and Radiation Protection held at the National Bureau of Standards, Gaithersburg, Maryland, USA, on March 8-12, 1987. The conference documented developments that have taken place in areas that were addressed during the first conference in 1982. A number of new topics, such as biological response modifiers, were included because of their emerging relevance to anticarcinogenesis and radiation protection. The organization of the material in this book does not follow the conference program; rather, we have attempted to provide a different sequence for didactic reasons. The ...
The dramatic decrease in the incidence of stomach cancer in industrialized countries during the past 50 years, which is yet to be fully explained, and the observation that carcinogenesis in laboratory animals can be inhibited by antioxidants, retinoids, and caloric restriction, among other influences, challenge us to press on in the search for practical means to prevent cancer. It is in relation to this goal that the studies summarized in this book have special significance. This book is based on the invited and contributed papers presented at the Third Internationai Conference on Anticarcinogenesis and Radiation Protection, held on October 15-21, 1989, in Dubrovnik, Yugoslavia. They cover a...
Food Storage Stability addresses one of the foremost problems faced by food processors - how to stabilize food once it is harvested. Using a holistic approach, the book discusses the changes responsible for food quality deterioration and considers strategies for minimizing or eliminating these degradative changes. Topics include: consumer perceptions and preferences, cellular changes, conversion of major constituents to more stable products, the effect of color and texture, packaging issues, and practical strategies for storing foods frozen, chilled, or at ambient temperature. Food Storage Stability is the only treatment of this subject that covers the diverse factors that influence quality retention in foods and integrates basic concepts in storage stability with practical applications. Food scientists and technologists concerned with changes in food quality are interested in ensuring that safe and appealing food products reach consumers - this is the book that will assist them with that important goal.
This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.
Among the various theories proposed to account for the process of aging, the free radical theory is of practical interest since it includes the possibility of retarding this process by administrating natural or synthetic antioxidants and free radical scavengers. The book "Free Radicals and Aging" summarizes knowledge accumulated during recent years in 42 reviews written by experts in the field. Aspects of free radical involvement in the intrinsic aging process and in age-related diseases, as well as the importance of the pro-antioxidant balance throughout life are discussed. Epidemiological studies from several European countries are reported showing correlations between low plasma levels of...
Annotation The breadth of scientific and technological interests in the general topic of photochemistry is truly enormous and includes, for example, such diverse areas as microelectronics, atmospheric chemistry, organic synthesis, non-conventional photoimaging, photosynthesis, solar energy conversion, polymer technologies, and spectroscopy. This Specialist Periodical Report on Photochemistry aims to provide an annual review of photo-induced processes that have relevance to the above wide-ranging academic and commercial disciplines, and interests in chemistry, physics, biology and technology. In order to provide easy access to this vast and varied literature, each volume of Photochemistry com...
The papers are arranged in eight sections, addressing: antimutagens in food; antimutagens and anticarcinogens in environmental toxicology; free radicals; antitumor initiators; antitumor promoters; aspects of mammalian and human genetics; molecular aspects of mutagenesis and antimutageneis; and oncog
How does dietary restriction affect the physiological and biochemical state of laboratory animals? How will the present conclusions affect further research? What are the implications for human health and safety assessment? These are the main questions asked in this book by leading international researchers. After a first look at feeding regimens and diets of laboratory animals, the book elaborates on a variety of age-associated toxicological and pathological endpoints including tumor development. The following sections detail the underlying mechanisms which may induce the broad spectrum of physiological and biochemical changes. This summary of current multidisciplinary research will enhance understanding of the practical applications and implications of dietary restriction.

Twenty years ago, the enzyme superoxide dismutase which uses the superoxide radical anion as its specific substrate was reported. With this discovery was born a new scientific field, in which oxygen, necessary for aerobi c 1 ife on thi s planet, had to be cons i dered also in terms of its toxicity and stresses. This stimulated the search for knowledge of active oxygen species in biology and medicine. Superoxide and other reactive oxygen species are now implicated in many disease processes. Major advances have been achieved during these past years with respect to free radical generation and mechanisms of free radical action in causing tissue injury. In parallel, the possibil ity of influencin...
