Stress is such an over-used word that it is at time difficult to define its core features. When is an environment stressful? What does a stressful environment do to the brain and to the body? What are the biological mechanisms by which a stressor affects us? How does stress contributes to the onset and the progression of mental disorders? How do the effects of stress change over the life-time of an individual? These are just some of the overarching questions addressed by this book, thanks to the contribution of some of the world leading experts on the neurobiology of stress at the pre-clinical and clinical levels. Topics include current advances on the neurobiology of stress on various neurobiological systems such as immune, hypothalamic-pituitary-adrenal (HPA) axis, neurogenesis and neuroplasticity, neurotransmitter (glutamate, noradrenaline, dopamine, serotonin and endocannabinoid), neuropeptides, cognition and emotional processing as well as in utero and early postnatal effects. The clinical chapters deal with the relationship of stress and mental disorders such as depression, posttraumatic stress disorder (PTSD), anxiety disorders, schizophrenia, bipolar disorder, substance abuse and addiction, dementia and age-related cognitive decline as well as resilience to stress. Thus, this book brings together some of the most updated and authoritative views on the effects of stress of brain and behavior.
Research now shows us that long-term activation of the stress cycle can have a hazardous, even lethal, effect on the body, increasing the risk of obesity, heart disease, depression, cancer, and other illnesses. This new edition of an award-winning book presents cutting-edge research on the effects of stress. Edited by one of the world's authorities in stress management, occupational psychology, and occupational medicine, Handbook of Stress Medicine and Health, Second Edition offers a completely revised and updated look at the different types of stress, including their characteristics, symptoms, duration, and treatment approaches. The text proposes a generic theory on stress and health and explores the relationship of stress to a variety of health outcomes, including heart disease, cancer, mental health, burnout, and complications of the endocrine and immune systems. It addresses the link between stress and personality, and discusses the impact of social support on various health conditions. The final chapters deal with stress and its consequences, such as the emotional processing of traumatic events, dealing with stress in families and in chronic disease, and coping with stress in the workplace. With contributions from the foremost leaders in the field, this authoritative book evaluates a wide range of psychosocial factors that contribute to many of today's major illnesses. It also proposes strategies for prevention and management, which will hopefully encourage future research into the reduction of stress.

This book is about doing innovative research to achieve sustainable and equitable change in people's health and well-being through improved interactions with the environment. It presents experiences from the field of ecosystem approaches to health (or ecohealth research) and some insights and lessons learned. It builds on previous literature, notably Forget (1997), Forget and Lebel (2001), Lebel (2003), and Waltner-Toews et al. (2008). Through case-studies and other contributions by researchers supported by Canada's International Development Research Centre (IDRC), the book presents evidence of real changes in conditions of people, their health, and the ecosystems that support them. These changes were derived from applications of an ecosystem approach to health in developing regions of the world. The book also illustrates the resulting body of applied, participatory, and action research that improved health and environmental management in developing countries and, in many cases, influenced policies and practices.
It is now more than ten years since Dr. Alec Jeffreys (now Professor Sir Alec Jeffreys, FRS) reported in Nature that the investigation of certain minisatellite regions in the human genome could produce what he termed DNA fingerprints and provide useful information in the fields of paternity testing and forensic analysis. Since that time we have witnessed a revolution in the field of forensic identification. A total change of technology, from serological or electrophoretic analysis of protein polymorphisms to direct investigation of the underlying DNA polymorphisms has occurred in a short space of time. In addition, the evolution and development of the DNA systems themselves has been rapid and spectacular. In the last decade we have progressed from the multilocus DNA fing- prints, through single locus systems based on the same Southern blot RFLP technology, to a host of systems based on the PCR technique. These include Allele Specific Oligonucleotide (ASO)-primed systems detected by dot blots, the "binary" genotypes produced by mapping variations within VNTR repeats demonstrated by minisatellite variant repeat (MVR) analysis, and yet other fragment-length polymorphisms in the form of Short Tandem Repeat (STR) loci. Hand in hand with the increasing range of systems available has been the development of new instrumentation to facilitate their analysis and allow us to explore the possibilities of high volume testing in the form of mass scre- ing and offender databases.
Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children's neurological development; to recommend a prevention strategy for protecting children's health and development.

This title includes a number of Open Access chapters. Environmental chemistry is an interdisciplinary field of study that involves the science of ecology as well as chemistry. Environmental chemistry covers the basic chemistry and biochemistry that occur naturally in the world around us. It focuses on the air, water, and land. Environmental science normally begins by determining the chemical reactions that are occurring in the environment when all systems are in balance and then goes on the discover how chemistry has changed when there is an imbalance caused by stress or pollution. The field is constantly changing, with new discoveries being made all the time. The availability of new and more sensitive instruments in analytical science is enabling the detection of smaller and smaller concentrations of pollutants in the environment. This new volume deals with a host of important topics in environmental chemistry, such as pesticide-related illnesses in humans and plants, the effects of litterfall in the soil of tropical forests, toxicants in various bodies of water, and much more.
Soils with high Ni contents occur in several parts of the world, especially in areas with ultramafic rocks which cause serious environmental impacts. This book aims to extend the knowledge on the risks and problems caused by elevated Ni contents and to cover the existing gaps on issues related to various aspects and consequences of high Ni contents in soils and plants. Nickel in Soils and Plants brings together discussions on Ni as a trace element and as a micronutrient essential for plant growth and its role in plant physiology. It analyzes the biogeochemistry of Ni at the soil plant interface, and explains its behavior in the rhizosphere resulting in Ni deficiency or toxicity, or Ni tolerance of various Ni hyperaccumulators. Included are Ni resources and sources, the origin of soil Ni, its geochemical forms in soils and their availability to plants, a special reference on soils enriched with geogenic Ni, such as serpentine soils, and the special characteristics of those ecosystems. Recent advancements in methods of Ni speciation, including the macroscale and X- ray absorption spectroscopy studies as well as serious views on Ni kinetics, are also covered. Written by a team of internationally recognized researchers and expert contributors, this comprehensive work addresses the practical aspects of managing Ni in soils and plants for agricultural production, and managing soils with high Ni levels by using organic and inorganic amendments. The text also addresses practical measures related to Ni toxicity in plants, the removal and recovery of Ni from high Ni wastes, and offers environmentally friendly innovative processes for mining Ni from soils containing high Ni levels.

Homeostasis. The health of an organism is influenced by external and internal changes that may lead to the loss of homeostasis. Under healthy conditions organisms compensate these changes. If compensation fails disease ensues. Attention will be paid to lifestyle, environmental changes, genetic makeup and health system. It will be answered how lifestyle, environment, genetic makeup and social conditions help to maintain or upset the biological balance and lead to cancer. Tumor formation. To understand this process the transfer of intracellular and the pathways of extracellular information (signal transduction) will be reviewed briefly. Loss of cellular balance may lead to cell death (.e.g. apoptosis) or to rapid cell growth of cells leading to tumor formation. Metastasis. Animal tumor models serve to understand the spread of the primary tumor cells to distant locations of the organism. Different types of tumors and metastases will be reviewed. |
