We are running a collective chemical fever that we cannot break. Everyone everywhere now carries a dizzying array of chemical contaminants, the by-products of modern industry and innovation that contribute to a host of developmental deficits and health problems in ways just now being understood. These toxic substances, unknown to our grandparents, accumulate in our fat, bones, blood, and organs as a consequence of womb-to-tomb exposure to industrial substances as common as the products that contain them. Almost everything we encounter—from soap to soup cans and computers to clothing—contributes to a chemical load unique to each of us. Scientists studying the phenomenon refer to it as “chemical body burden,” and in The Body Toxic, the investigative journalist Nena Baker explores the many factors that have given rise to this condition—from manufacturing breakthroughs to policy decisions to political pressure to the demands of popular culture. While chemical advances have helped raise our standard of living, making our lives easier and safer in many ways, there are costs to these conveniences that chemical companies would rather consumers never knew about. Baker draws back the curtain on this untold impact and assesses where we go from here.

This book describes the mathematical and diagrammatic techniques employed in the popular many-body methods to determine molecular structure, properties and interactions.

Human hair is the subject of a wide range of scientific investigations. Its chemical and physical properties are of importance to the cosmetics industry, forensic scientists, and to biomedical researchers. This updated and enlarged fourth edition continues the tradition of its predecessor as being the definitive monograph on the subject. It now contains new information on various topics including: chemical hair damage, the cause of dandruff, skin and eye irritation, hair straightening, and others. Chemical and Physical Behavior of Human Hair is a teaching guide and reference volume for cosmetic chemists and other scientists in the hair products industry, academic researchers studying hair and hair growth, textile scientists, and forensic specialists.

The largest interventional and monitoring studies to date worldwide give us an excellent overview of our current state of knowledge on the physiological interactions between nutrition and exercise. This wealth of evidence covers aspects like body weight, metabolism, fatty tissue, hormones, the cardiovascular system and skeletal structures – all ultimate determinants of immunity. The book you hold in your hands is based on the findings generated by such long-term investigations. Herein, each topic is dealt with page by page in an understandable manner. The reader will find illustrations and discussions of key physiological adaptation mechanisms and the basic principles of preventive healthcare. This non-fiction work has been written to be easily comprehensible for all individuals interested in learning the salient facts about the popular subjects of health, fitness and nutrition. For this 3rd edition, the text has been revised and updated to the state of the art in science and medicine, including the addition of 11 new topics.

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
