Book Description
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.

Book Description
Tbis volume discusses and evaluates the use of neurotoxins to produce animal models of human neurodegenerative diseases. Tbe models presented use neuro toxins to induce some or most of the pathophysiological changes (including behavioral) that characterize the most studied motor neuron disorders and cogni tive disorders (dementia) in humans. Within the biomedical research community, there is little doubt about the utility of such models. But with increasing frequen cy, individuals concemed with animal rights question the validity of such models and argue that they actually produce no useful information for understanding or developing treatments for human disorders. Each of the chapters will address this issue, considering the utility, validity, generalizability, and limitations of the models presented. Chapter 1 begins with a brief review of the ethics of animal use in neuro biological research, inc1uding a discussion of the criteria that may be used to evaluate animal models of human disease and extrapolate from the model to appropriate questions regarding humans. The limitations of such extrapolation are also discussed, with special consideration of issues specific to the use of neurotoxins. Chapter 2 extends this theme with further consideration of issues and strategies involved in developing neurotoxin-induced models of neuro degenerative disorders and assessing risk factors associated with neurotoxin ex posure. It then narrows to evaluate the use of a model systems approach to explore neurotoxin-induced leaming and memory deficits in animals as related to humans with dementia.

Book Description
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.

Book Description
N eurotoxicology is a broad and burgeoning field of research. Its growth in recent years can be related, in part, to increased interest in and concern with the fact that a growing number of anthropogenic agents with neurotoxic potential, including pesticides, 1ead, mercury, and the polytypic byproducts of combustion and industrial production, continue to be spewed into and accumulate in the environment. In addition, there is great interest in natural products, including toxins, as sources of therapeutic agents. Indeed, it is well known that many natural toxins ofbroadly differing structure, produced or accumulated for predatory or defensive purposes, and toxic agents, accumulated incidentalIy by numerous species, function to perturb nervous tissue. Components of some of these toxins have been shown to be useful therapeutic agents and/or research reagents. Unfor of some neurotoxicants of anthropogenic ori tunately, the environmental accumulation gin, expecialIy pesticides and metals, has resulted in incidents ofhuman poisoning, some of epidemic proportion, and high levels of morbidity and mortality. Furthermore, an increasing incidence of neurobehavioral disorders, some with baffling symptoms, is confronting clinicians. It is not clear whether this is merely the re suit of increased vigi lance and/or improved diagnostics or a consequence of improved health care. In any case, the role of exposure to environmental and occupational neurotoxicants in the etiology of these phenomena, as well as neurodegenerative diseases, is coming under increasing scrutiny and investigation.

Book Description
The specific topic, “Isoquinolines And Beta-Carbolines As Neurotoxins And Neuroprotectants – New Perspectives In Parkinson`S Disease Therapy,” was chosen in light of accumulating neurobiological evidence indicating that, in addition to exogenous neurotoxins (e.g., 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine [MPTP]), endogenous compounds may play an important role in the most common neurodegenerative disorders (e.g., Parkinson`s disease). Two groups of amine related compounds, which appeared chemically like MPTP, were detected in human brain and cerebrospinal fluid (CSF): ß-carbolines (BCs) and tetrahydroisoquinolines (TIQs). These are heterocyclic compounds formed endogenously from phenylalanine/tyrosine (TIQs) and tryptophan, tryptamine, and 5-hydroxytryptamine (BCs), respectively and exert a wide spectrum of psychopharmacological and behavioral effects. The TIQs and BCs may bind to their own high affinity sites on neuronal membranes associated with or located close to the receptors of neurotransmitters. Research on TIQs and BCs is stimulated also by their possible role in pathological conditions, especially parkinsonism and alcoholism. Recently, clinical interest has been spurred by their role as neuroprotective, and even neurorestorative, anticonvulsant and antiaddictive, substances. In this book we are going to summarize, for the first time, the results from behavioral, neurochemical and molecular experiments, which demonstrate a wide spectrum of TIQs and BCs effects - from their rather mild neurotoxic actions to the important neuroprotective and antiaddictive properties. Additionally, the recent results of experimental studies in vivo have allowed a much better understanding and simultaneous comparison of the neurochemical and molecular mechanisms underlying the neuroprotective and neurotoxic actions of endogenous TIQs and BCs and have pointed to the possibility of their therapeutic applications in neurodegenerative diseases such as Parkinson's disease.

Book Description
This handbook is a reference source for identifying, characterizing, instructing on use, and describing outcomes of neurotoxin treatments – to understand mechanisms associated with toxin use; to project outcomes of neurotoxin treatments; to gauge neurotoxins as predictors of events leading to neurodegenerative disorders and as aids to rational use of neurotoxins to model disease entities. Neuroprotection is approached in different manners including those 1) afforded by therapeutic agents – clinical and preclinical; or 2) by non-drug means, such as exercise. The amorphous term ‘neurotoxin’ is discussed in terms of the possible eventuality of a neuroprotectant producing an outcome of excess neuronal survival and a behavioral spectrum that might produce a dysfunction – akin to a neurotoxin’s effect. This new edition significantly expands on the information provided in the first edition, providing the latest research in neurotoxicity and highlighting the relationship between specific neurotoxins and the neurodegenerative disorders they can cause. It also includes new sections on the neurotoxicity of heavy metals, fungi, and snake venom. The Handbook of Neurotoxicity is thus an instructive and valuable guide towards understanding the role of neurotoxins/neurotoxicity in the expansive field of Neuroscience, and is an indispensable tool for laboratory investigators, neuroscientists, and clinical researchers.
