Book Description
Research has clearly established a link between omega fatty acids and general health, particularly cardiovascular health. Omega Fatty Acids in Brain and Neurological Health, Second Edition, illustrates the importance of omega-3 fatty acids in longevity, cognitive impairment and structure and function of the brain's neurons and also the adverse effects of omega-6 fatty acids on neurological function. This book encompasses some of the most recent research on the links between omega fatty acids and the developing brain, aging, dementia, Alzheimer's disease and multiple sclerosis, including the role of omega-3 fatty acid supplements on hippocampal neurogenesis, substantia nigra modulation, migraine headaches, the developing brain in animals, sleep and neurodegenerative diseases. This completely updated second edition focuses on the counterbalancing dietary and tissue omega-6 fatty acids as well as it studies the effects in pregnancy and early infancy, animal model studies and autoimmune neurological diseases. - Provides a comprehensive introduction to omega-3 and omega-6 fatty acids in neurological health and directions for future research - Features novel focus on the adverse effects of omega-6 fatty acids on neurological function and the counterbalancing of dietary and tissue omega-6 - Illustrates the importance of omega-3 fatty acids in longevity and cognitive impairment - Features new chapters on early effects in pregnancy and early infancy, animal model studies and autoimmune neurological diseases - Discusses links between omega fatty acids and the developing brain, aging, dementia, Alzheimer's disease and multiple sclerosis, including the role of omega-3 fatty acid supplements

Book Description
“Empowering and thoroughly researched, this book offers useful contemporary analysis and possible solutions to one of the greatest threats to democracy.” —Kirkus Reviews Editors’ choice, The New York Times Book Review Recommended reading, Scientific American Why should we care about having true beliefs? And why do demonstrably false beliefs persist and spread despite bad, even fatal, consequences for the people who hold them? Philosophers of science Cailin O’Connor and James Weatherall argue that social factors, rather than individual psychology, are what’s essential to understanding the spread and persistence of false beliefs. It might seem that there’s an obvious reason that true beliefs matter: false beliefs will hurt you. But if that’s right, then why is it (apparently) irrelevant to many people whether they believe true things or not? The Misinformation Age, written for a political era riven by “fake news,” “alternative facts,” and disputes over the validity of everything from climate change to the size of inauguration crowds, shows convincingly that what you believe depends on who you know. If social forces explain the persistence of false belief, we must understand how those forces work in order to fight misinformation effectively. “[The authors] deftly apply sociological models to examine how misinformation spreads among people and how scientific results get misrepresented in the public sphere.” —Andrea Gawrylewski, Scientific American “A notable new volume . . . The Misinformation Age explains systematically how facts are determined and changed—whether it is concerning the effects of vaccination on children or the Russian attack on the integrity of the electoral process.” —Roger I. Abrams, New York Journal of Books

Book Description
Over 400 years ago, Swiss alchemist and physician Paracelsus (1493-1541) cited: "All substances are poisons; there is none that is not a poison. The right dose differentiates a poison from a remedy." This is often condensed to: "The dose makes the poison." So, why are we overtly anxious about intoxications?In fact, poisons became a global problem with the industrial revolution. Pesticides, asbestos, occupational chemicals, air pollution, and heavy metal toxicity maintain high priority worldwide, especially in developing countries. Children between 0 and 5 years old are the most vulnerable to both acute and chronic poisonings, while older adults suffer from the chronic effects of chemicals. This book aims to raise awareness about the challenges of poisons, to help clinicians understand current issues in toxicology.

Book Description
The key target systems and organismal effects of 'Fish Toxicology' describe the key target organ systems for chemical impacts in fish, how chemicals produce cancer in these animals and how fish can develop resistance to chemical or drug toxicity. Therefore in fish, as in humans, livestock, companion animals, equines, wild animals and laboratory animals, pharmacology and toxicology cover all researches involved with basic and clinical pharmacology and toxicology. Human medicines may potentially induce similar pharmacological and toxicological actions in fish. Fish not only play an important role in the demand of food for humans but they are widely used as 'model organisms' for various biological experiments. Fish and other aquatic organisms are exposed from different substances like chemicals, drugs, toxicants or pollutants. Most of these substances or their metabolites cause pollution, leading to toxicity and various diseases including cancer. Therefore, the fishery scientists must develop the skill in recognizing the action and toxicity of such toxic substances in fish.

Book Description
Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.
