This book was released on 2017-05-11 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mounting evidence shows that increasing numbers of children are being diagnosed with neurodevelopmental disorders, and it is clear that this increase cannot be explained by genetic background alone. A number of studies, including epidemiological studies, have found an association between in-utero and childhood exposure to certain chemicals, such as endocrine disruptors, psychoactive pharmaceuticals, volatile organic chemicals, persistent organic compounds and heavy metals, and children’s brain development. Yet, the mechanisms by which these chemicals impair brain development and function are not fully understood. In addition, little is known about how these chemicals enter and accumulate in the brain. Experimental approaches are essential to understand how those harmful chemicals enter children’s brain and pose discrete effects on specific brain sites. These approaches include the following: improvement of technologies for the detection and measurement of neuroendocrinological and behavioral changes in animal models: development of analytical methods for the identification and quantification of chemicals and their metabolites in the brain; development of in vitro cell line assays; and imaging technologies to illustrate cellular functions. In this research topic, we collected articles that provide state-of-the-art science and technologies that can help us identify environmental chemicals that influence brain development. We also included articles that lead to a better understanding of the actions and dynamics of these chemicals. The articles in this research topics supplied novel information about harmful endpoints of environmental chemicals. The reviews demonstrated the typical and novel interactions between environmental chemicals and the developing brain. We believe that these studies would lead to further understanding of neurodevelopmental disorders caused by environmental factors.

This book was released on 1990-02-01 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to toxic chemicalsâ€"in the workplace and at homeâ€"is increasing every day. Human behavior can be affected by such exposure and can give important clues that a person or population is in danger. If we can understand the mechanisms of these changes, we can develop better ways of testing for toxic chemical exposure and, most important, better prevention programs. This volume explores the emerging field of neurobehavioral toxicology and the potential of behavior studies as a noninvasive and economical means for risk assessment and monitoring. Pioneers in this field explore its promise for detecting environmental toxins, protecting us from exposure, and treating those who are exposed.

Available in PDF, EPUB and Kindle. Book excerpt: The exponential increases in neurodevelopmental disorders implicate both genetic causes and environmental factors. Flame-retardants, pesticides, plasticizers, and other every-day products contain chemicals shown to affect thyroid hormone signaling, which if disrupted can result in significant impairment to IQ. Across entire populations, such effects spell large-scale social and economic consequences. In this book Barbara Demeneix suggests what can and must be done to halt and reverse this disturbing trend.
Download or read book Environmental Neurotoxicology written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.
Download or read book Sensing the Environment Regulation of Local and Global Homeostasis by the Skin s Neuroendocrine System written by Andrzej T. Slominski and published by Springer Science & Business Media. This book was released on 2012-06-02 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.

Available in PDF, EPUB and Kindle. Book excerpt: Neuroendocrine Regulation of Animal Vocalization: Mechanisms and Anthropogenic Factors in Animal Communication examines the underpinning neuroendocrine (NE) mechanisms that drive animal communication across taxa. Written by international subject experts, the book focuses on the importance of animal communication in survival and reproduction at an individual and species level, and the impact that increased production and accumulation of endocrine-disrupting chemicals (EDCs) can have on these regulatory processes. This book discusses sound production, perception, processing, and response across a range of animals. This includes insects, fish, bats, birds, nonhuman primates, infant humans, and many others. Some chapters analyze how neuroactive substances, endocrine control, and chemical pollution affect the physiology of the animal's perceptive and sound-producing organs, as well as their auditory and vocal receptors and pathways. Other chapters address the recent approaches governments have taken to protect against the endocrine disruption of animal (vocal) behaviors. The book is a valuable resource for researchers and advanced students seeking first-rate material on neuroendocrinological effects on animal behavior and communication. - Serves as the most comprehensive cross-taxa study of its kind, revolutionary in its focus on the impacts of EDCs on the processes guiding animal communication - Emphasizes the importance of production, perception and processing of acoustic vocalization for survival - Analyzes recent governmental policies and protections against the effects of EDCs on humans and wildlife

Download or read book Endocrine Disruptors Brain and Behavior written by Heather B. Patisaul and published by Oxford University Press. This book was released on 2017-04-10 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our world and bodies are becoming increasingly polluted with chemicals capable of interfering with our hormones and thus, possibly, our present and future neural and mental health. As authors Heather Patisaul and Scott Belcher outline, there is a large lack of data and evidence in this causal relationship, which begs a need for further study to accelerate progress in the endocrinology and neuroendocrinology fields. Endocrine Disruptors, Brain, and Behavior focuses on if and how these chemicals, known as endocrine disrupting compounds (EDCs), affect the development and function of the brain and might be contributing to neural disorders rapidly rising in prevalence. The book provides an overall synthesis of the EDC field, including its historical roots, major hypotheses, key findings, and research gaps. The authors explain why even the concept of endocrine disruption is controversial in some circles, how differing definitions of endocrine disruption and what constitutes an "adverse" outcome on the brain shape public policy, and where the current capacity by different stakeholders (industry, academia, regulatory agencies) to evaluate chemicals for safety in a regulatory context begins and ends. The book concludes with suggestions for future research needs and a summary of emerging technology which might prove capable of more effectively evaluating existing and emerging chemicals for endocrine disrupting properties. As such, it provides the context for interdisciplinary and innovative input from a broad spectrum of fields, including those well-schooled in neuroscience, evolutionary biology, brain, behavior, sex differences, and neuroendocrinology.

Download or read book Neuroendocrine Immune System Interactions written by Jan Pieter Konsman and published by Springer Nature. This book was released on 2023-03-03 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concepts of the neuroendocrine system and the immune system emerged more or less simultaneously in the second half of the 20th century. Although these systems have a high degree of autonomy, it has also become clear that they interact in many ways and at different levels. This book focuses on the neuroendocrine and immune interactions that are fundamental to normal development and maintenance of health. The first introductory chapters are devoted to the historical and philosophical concepts within the field, as well as evolutionary considerations, offering critical interdisciplinary perspectives on the development of this field of research. Without attempting an exhaustive overview, the book then introduces some of the regulatory pathways that mediate interactions between the neuroendocrine and immune systems and examines modulating factors such as age and sex. In addition, several chapters address the importance of neuroendocrine-immune interactions in some disease states. Readers can expect to gain a broad perspective of neuroendocrine-immune interactions in development, health, and disease, along with a critical evaluation of current methods used in the field. Given its scope, the book is essential reading for undergraduate and graduate students with an interest in neuroendocrinology, neuroimmunology, and neuroscience, as well as postdoctoral fellows and established researchers seeking a comprehensive overview and historical perspective of the field of neuroendocrine-immune interactions.

Download or read book From Neurons to Neighborhoods written by National Research Council and published by National Academies Press. This book was released on 2000-11-13 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.
