Hormesis is defined as any circumstance in which exposure of a cell or organism to a low dose of a substance or condition results in an adaptive stimulatory/beneficial outcome, while exposure to a high dose results in an inhibitory / detrimental outcome. When plotted on a graph the shape of the dose response curve is biphasic, the hallmark of hormesis. This groundbreaking book "Hormesis: A Revolution in Biology, Toxicology and Medicine" describes why and how hormesis is a fundamental feature of all living systems and is based on the evolutionary principle of selection for genetic traits that confer the ability to respond adaptively to adverse environmental conditions. Using numerous specific examples the authors explain why knowledge of hormesis is important for our health, our environment, and the future of our planet. Several chapters of the book describe emerging research findings that elucidate the molecular and cellular underpinnings of the biphasic dose response/hormesis. The implications of the tapping of cellular systems that underlie hormesis for the discovery and optimization of new drugs and dietary formulations are described.

From environmental protection policy to medical practice, it is critical that leaders recognize and understand hormesis, and incorporate it into their decision making process. The authors propose that the prevention of major diseases, including diabetes, obesity and cardiovascular disease can be achieved using hormetic approaches. Scientists, physicians, environmental gurus and anyone interested in the science underlying biology and medicine will benefit from reading this book.

Edward J. Calabrese, Ph.D. is a Professor and Program Director of
Environmental Health Science, at the University of Massachusetts in Amherst.

His research focuses on environmental toxicology with an emphasis on biological factors including genetic and nutritional factors that enhance susceptibility to pollutant toxicity and the environmental implications of toxicological hormesis. Dr. Calabrese has researched extensively in the area of host factors affecting susceptibility to pollutants, and is the author of more than 300 papers in scholarly journals, as well as 24 books in the field of toxicology and environmental pollution. Dr. Calabrese has received numerous awards including, most recently, the prestigious Marie Curie Prize.

Zusammenfassung

Hormesis is a poorly understood phenomenon affecting all forms of life on earth. This groundbreaking book summarizes and analyzes the various positives of hormesis in an attempt to reveal hormesis as a fundamental principle of biomedical sciences as a whole.
