It synthesizes findings from behavioral and population genetics, evolutionary biology and criminology and presents the latest findings in twin studies, adoption cohort studies, molecular genetics and animal models for human aggression. Also included is a detailed analysis of the legal implications of genetics and crime research and strategies for rehabilitation.

This book draws together contributions from some of the leading investigators in the field of autism to consider specific problem areas in current research. Each contributor brings expertise from a different field, providing a balanced view of the whole spectrum of study of this disorder. It covers four main areas: Twin and family studies indicate that the heritability of the underlying liability to autism exceeds 90% and point to a multifactorial causation, involving a relatively small number of susceptibility genes. The book discusses this issue in detail, along with the problem of why some additional symptoms are associated with autism while others are not. New techniques are available for examining the neurobiology of autism. The book contains results from imaging studies showing the contributions of different brain regions to autism. It includes neuropathological data and examines the neuropharmacology of autism. There is considerable discussion concerning the fundamental psychological deficit in children with autism. There is good evidence that «Theory of Mind» deficits are associated with autism and this issue is discussed in the book, as are other competing possibilities. The most important practical question facing medical and psychological practitioners is how to help children with autism. The evidence relating to possible psychological or psychiatric interventions for rehabilitation of children with autism is examined in detail. Drug treatments have generally been disappointing in this field and there is one chapter devoted specifically to this problem. The book focusses ultimately on intervention studies and so is of practical relevance to people interested in helping autistic children. In addition, it provides a very convenient summary of the principal controversies which currently exist in research on autism.

To understand the brain and its devastating diseases, we need to reveal the mechanisms that produce it and the ways in which it can constantly change throughout a lifetime. This book features a timely and insightful discussion between developmental neurobiologists and clinicians who deal with disorders of the nervous system. Chapters in this book deal specifically with cell fate determination, cell migration and disorders of cell migration; current concepts and new ideas about cortical arealisation, and disorders which can arise from incorrect arealisation; genes implicated in the development of cortical connectivity and related pathologies such as schizophrenia and synaesthesia; and susceptibility genes for cognitive disorders such as schizophrenia, autism, dyslexia, and attention deficit disorder.

This book brings together material on all aspects of immunological tolerance. Basic mechanisms of tolerance are examined in detail, including mechanisms of peripheral T cell tolerance, molecular and genetic mechanisms for maintaining self tolerance, partial T cell activation, and the role of apoptosis in tolerance. Careful consideration is also given to the clinical applications of our understanding of immunological tolerance, with specific chapters dealing with T cell activation during tumour therapy, antiantigen specific immune suppression, tolerance in infectious diseases, tolerance during pregnancy, and tolerance during various autoimmune diseases.

A timely volume dealing with the evolutionary and structural links between the clotting and fibrinolytic proteins and plasminogen-related growth factors. The role of individual domains for enzymatic proteins and plasminogen-related growth factors is also comprehensively examined.

The field of lymphokine research has grown in parallel to the exciting developments around the two sets of cells which defend the body. While lymphokines are the «property» of immunologists, the molecular regulators of hemopoiesis (CSFs) belong to the hematologists. This book offers the rare opportunity to examine these separate fields of expertise together.

Many common human diseases have a multifactorial origin: they are influenced by a person's genetic predisposition as well as by factors in the environment. This volume deals with the application of recombinant DNA techniques to the identification of diseases that have more than one inherited component. Focus is on the polygenic factors responsible for coronary atherosclerosis. Several other disorders having a polygenic origin are also discussed, including hypertension, diabetes mellitus, psychiatric diseases, and autoimmune (HLA-related) disorders. Problems raised by the study of different families or different populations are covered, as well as the possibility of applying molecular techniques to disease prevention–for example, through gene therapy. Also, some of the ethical issues that relate to human gene mapping are briefly explored.

This book is a comprehensive and up-to-date account of where we stand in immunological strategies for preventing or treating type 1 diabetes (T1D). Brings together contributions from the leaders in the arena of clinical immunotherapy, not limited to the diabetes field exclusively, in order to delineate a road-map that would lead to future clinical trials. The book integrates information from human and animal studies. The book considers T1D within the broader context of autoimmune disease. The format contains several discussions, which address specific questions and provides guidelines for future strategies and solutions for discovering a cure.

This book explores the possibility that life exists on Mars. It provides an interdisciplinary overview of the early evolution of life in hydrothermal ecosystems on Earth, focusing on the problem of remote sensing and incorporating geological work relevant to the search for evidence of early life on Earth and Mars. It discusses the belief that studying thermal spring deposits as part of this search may be the best opportunity to test whether life on earth is a «unique experiment,» or whether there is life elsewhere in the solar system.

Dengue virus is a member of the Flaviviridae family, which includes viruses associated with human diseases such as yellow fever, Japanese encephalitis and hepatitis C. Dengue fever is transmitted by mosquitoes, principally Aedes aegypti. There are four serotypes of dengue virus, of which DENV-2 has been the most prevalent in many recent epidemics. Following primary infection, lifelong immunity develops, preventing repeated assault by the same serotype. However, the non-neutralizing antibodies from a previous infection or maternally acquired antibodies are thought to form complexes with a different serotype during a subsequent infection and cause dengue haemorrhagic fever/dengue shock syndrome, which can be fatal. There is no treatment or vaccine available today that can combat this emerging and uncontrolled disease. This book features contributions from the world’s leading researchers working on dengue and related flaviviruses who examine the current state of the art in the molecular biology of the dengue virus. Particular emphasis is placed on the structure and function of the virus and the targeting of virus proteins by potential antiviral agents. The pathogenesis of dengue and dengue haemorrhagic fever are discussed in detail, especially the target cells and the specific receptors on these cells, thereby developing a clear overview of host and viral factors that contribute to dengue haemorrhagic fever. Finally, the book reviews the therapeutic options, paying particular attention to ways in which vector, host and environment can play a critical role in the spread of this disease. With dengue fever and other emerging viral diseases becoming increasingly prevalent around the world, this book provides valuable insight into the virus that causes this disease and potential ways to manage it. It is essential reading for all those working in tropical diseases, public health and virology. Praise from the reviews: «The book provides an excellent summary of dengue/flavivirus research and is important for individuals and institutions interested in emerging infectious diseases.» MICROBIOLOGY TODAY

Much recent research in evolutionary developmental biology has focused on the origin of new body plans. However, most evolutionary change at the population and species level consists of tinkering: small-scale alterations in developmental pathways within a single body plan. Such microevolutionary events have been well studied on a population genetic level and from the perspective of adaptive phenotypic evolution, but their developmental mechanisms remain poorly studied. This book explores both theoretical and practical issues of tinkering. It features a wide range of perspectives to address several fundamental questions. How does tinkering occur developmentally, and how is it manifested phenotypically? Are the developmental mechanisms by which tinkering occur different from those that underlie larger evolutionary changes? What are the developmental constraints on tinkering? And how do we test hypotheses about microevolutionary shifts in development from the fossil record? With contributions from experts in a range of fields, this fascinating book makes exciting reading for anyone studying evolution, developmental biology or genetics.

Anaphylaxis is an immediate-type allergic reaction involving the whole organism. It is the most life-threatening allergic condition. Although there are few exact epidemiological data regarding prevalence, estimates regarding insect sting anaphylaxis range from 1-3% in the general population, but much higher values have been reported by some authors for food and drug-induced anaphylaxis. Anaphylaxis is the main acute killer of allergic individuals. Although anaphylaxis was discovered at the beginning of the 20th century, there are still many unresolved issues. These include non-IgE-mediated anaphylactoid reactions, non-immunologically mediated anaphylactoid (pseudo-allergic) reactions, pathophysiological events at the microcirculatory level, appropriate therapy for the acute reaction, strategies for prevention, public education about the problem and new approaches to prevention and therapy at the IgE level. All these subjects are discussed in this book. Since anaphylaxis occurs acutely and is unforeseen, it is very difficult to organize controlled studies regarding therapy and prevention. The spectrum of symptomatology covers many clinical areas (skin, respiratory, cardiovascular and gastrointestinal system), therefore inter-disciplinary approaches are necessary for progress in the field. There is widespread uncertainty among physicians about therapy, especially concerning self-administered treatment. In this important book, an multidisciplinary group of experts explore the pathophysiology of different types of anaphylactic and anaphylactoid reactions. Evidence is presented on the epidemiology of these conditions while problems relating to diagnosis, therapy and prevention are examined in detail. This thorough and up-to-date coverage of the subject will be of great interest to all clinical immunologists, researchers and physicians who deal with this life-threatening condition.

Dietary supplements can contain a wide variety of ingredients, either singly or in combination, including nutrients, botanicals and 'bioactive components' commonly found in foods. They are marketed and used by consumers for a range of reasons: to enhance «well-being», as traditional medicines, for health promotion or disease risk reduction, and as alternatives or complements to conventional drug therapies. On a global basis, the dietary supplement industry has enjoyed rapid growth, becoming a multi-billion dollar enterprise over the last 10 years. This growth has been associated with significant changes in both the types of products available and the reasons for using these products. In many cases, these changes have occurred without the benefit of a sound scientific basis for evaluating the safety and efficacy of these products under the new conditions of use and frequently the same limited scientific evidence is used, even though current product composition, user populations, purported beneficial effects, and conditions of use may differ significantly from the available evidence or historical usage. This book presents systematic examinations of the scientific data that are available and/or needed to substantiate and evaluate the safety and efficacy of dietary supplements. A series of case studies that are illustrative of the types of scientific challenges that have been encountered in substantiating safety and efficacy for various product types are employed to point out some of the successes but also frustrations that have occurred in recent years. Discussions among presenters and participants identify the lessons learned from these experiences and formulate ideas for improved approaches to identifying research needs and for enhancing the quality and relevance of the scientific evidence available for policy decisions. Dietary Supplements and Health constitutes a useful resource for nutritionists, biochemists, public health researchers and anyone interested in herbal, alternative medicines.

A comprehensive volume examining the fundamental questions raised by reductionists' theory about levels of explanation necessary to understand biological systems. The book evaluates the enormously powerful techniques of molecular biology, and analyzes precisely how molecular information has improved our understanding of fundamental biological processes.

This book features scientists from a broad spectrum of disciplines discussing recent data on aggression in laboratory animals with particular reference to possible implications for understanding human aggression. Chapters focus on the major current experimental issues in the study of aggression in humans and animals. The extensive discussions deal with specific problems of interpretation at the molecular level, as well as general issues relating to our understanding of human and animal aggression.

Tissue engineering takes advantages of the combined use of cultured living cells and three-dimensional scaffolds to reconstruct adult tissues that are absent or malfunctioning. This book brings together scientists and clinicians working on a variety of approaches for regenerating of damaged or lost cartilage and bone to assess the progress of this dynamic field. In its early days, tissue engineering was driven by material scientists who designed novel bio-resorbable scaffolds on which to seed cells and grow tissues. This ground-breaking work generated high expectations, but there have been significant stumbling blocks holding back the widespread use of these techniques in the clinic. These challenges, and potential ways of overcoming them, are given thorough coverage in the discussions that follow each chapter. The key questions addressed in this book include the following. How good must cartilage repair be for it to be worthwhile? What is the best source of cells for tissue engineering of both bone and cartilage? Which are the most effective cell scaffolds? What are the best preclinical models for these technologies? And when it comes to clinical trials, what sort of outcome measures should be used? With contributions from some of the leading experts in this field, this timely publication will prove essential reading for anyone with an interest in the field of tissue engineering.

Prominent clinicians and researchers from diverse disciplines discuss the basic cell and molecular biology of steroid action and sex steroids' effects on the nervous and immune systems. Provides an integrated evaluation of the advantages and disadvantages of hormone replacement therapy.

Over recent decades vast amounts of biological data have been accumulated. However, it is becoming increasingly difficult to apply traditional theoretical methods to the formulation of coherent pictures of cell and organ function because it is no longer possible for a human theorist to integrate all of the available information. Instead, computer technologies must now be used to perform this integration. This book brings together contributions from many different fields to summarize the current status of computer-assisted modelling of biological processes. The initial chapters deal with fundamental developments in hardware, software and mathematics that underlie current approaches to biological modelling. Next, different approaches to collating data on gene structure and function are presented. These databases form a vital resource for any investigator trying to construct an integrated picture of particular biological systems. Cell signalling systems form a particularly complicated aspect of all cellular function and are important both in the understanding of basic cellular processes and in selecting targets for drugs. Recent approaches to integrating data on cell signalling into computer models are covered. Further chapters build on these approaches to show how computerized models of intact cells can be developed. Finally, approaches to the computer modelling of whole organs such as the heart are presented. The role of computer modelling in drug design is the subject of the final chapter and is also touched on throughout the discussions.

Over the last several years, immunologists have re-discovered the importance of regulatory lymphocytes, formerly termed 'suppressor cells'. Many recent reports have documented their existence, effector functions and potential therapeutic benefits in autoimmunity and transplantation. However, even though modern techniques have allowed us to get a much more detailed picture of these cells, they are still highly controversial. Several unresolved issues responsible for this dilemma are discussed in this book: it is difficult to grow and clone such cells, their phenotypes and effector functions are diverse and can sometimes easily be lost, and it is not well understood how they interact with antigen-presenting cells. This book contains contributions from leading investigators from around the world, including lively discussion of the current state of the art in studies of regulatory lymphocytes. Topics featured are the physiological control of autoimmunity, the role of antigen-specific cells in various diseases and disease models and effector mechanisms. Therapeutic applications are considered, particularly for type 1 diabetes, tissue transplantation and the control of viral infection. This important and groundbreaking book should be of interest to all immunologists.

This book features contributions from experts in cell biology, genetics, neurobiology, immunology and structural biology. The unifying element is that they all study processes of cell shape change and motility. Several key questions in this field of research are discussed: What are the organising principles behind cell shape change? Are there ‘master switches’ present in every cell type? How are extracellular signals interpreted by the cell in order to activate intracellular mechanisms? What is the influence of the extracellular matrix on cell movement and internal signalling pathways? How do pathogens subvert cellular systems in order to stimulate or block their uptake? The book addresses all of these important questions. Data are presented on the key proteins that regulate cell shape: the GTP binding proteins of the Rho family. There are also extensive discussions of the potential applications of the data to clinical problems, particularly that of cell motility in cancer.

The past decade has seen mounting global concern regarding viral outbreaks such as SARS, avian influenza and West Nile virus. In 2004 and 2005, reports of bird-to-human, and possible human-to-human, transmissions of the H5N1 influenza viruses raised fears that these viruses could cause a pandemic on the scale of the Spanish flu pandemic of 1918. Previous to this, a novel coronavirus had been identified as the aetiological agent of the severe acute respiratory syndrome (SARS), a new respiratory viral disease that emerged at the end of 2002 and caused profound disturbances in over 30 countries worldwide in 2003. It is not known whether the SARS coronavirus will re-emerge, especially since its origins and potential reservoir(s) are unresolved. However, these outbreaks have shown that these viruses can emerge in any part of the world at any time. This book critically evaluates the latest scientific evidence on novel or re-emerging viral diseases and brings together contributions from world experts on this topic, explaining best practice in their area, and discussing lessons learned and how best to collaborate to prevent and control future outbreaks. Topics covered include: the latest advances in virology, particularly in the area of epidemiology diagnostics animal models for viral infection antiviral and vaccine development Novel and Re-emerging Respiratory Viral Diseases offers a comprehensive and interdisciplinary account of all aspects of the topic, from basic molecular biology to public health issues, and is therefore essential reading for virologists, infectious disease specialists, public health managers, researchers and epidemiologists, as well as those working in vaccine development, pharmaceutical medicine and drug discovery

Cigarette smoking is estimated to lead to 4.9 million premature deaths per year worldwide. This is predicted to rise to 10 million by 2020. In western countries it kills half of all smokers who fail to stop. The prevailing model for tobacco addiction is that nicotine from cigarettes rewards smoking and punishes abstinence, tapping into a motivational system of operant conditioning that requires no conscious awareness. However, there are also accounts which involve cognitive biases and the effect of nicotine on impulse control. The brain pathways involved have been studied extensively, but the role of different nicotine receptor subtypes and other neurotransmitter systems is still subject to debate. In western countries, cigarette smoking as an adult has a heritability of 30-50% and candidate genes have been identified that may contribute in part to addiction susceptibility. Many socio-cultural correlates of cigarette smoking have been established, but a comprehensive model that accounts for these and links them with the psychobiological aspects of nicotine addiction has not been forthcoming. Structured behavioural support programmes aid cessation attempts, as do a number of pharmacotherapies, most notably nicotine replacement treatments and bupropion, but the underlying mechanisms are unclear. This book deals with the problems involved in understanding and treating nicotine and tobacco addiction. Topics covered include the nature of the worldwide health problem posed by cigarette smoking, the psychodynamics of cigarette addiction, and the basic pharmacology and biochemistry of nicotine and its effect on the brain. Further chapters analyse the genetic basis of susceptibility to nicotine addiction. Finally, the contributors address approaches to therapy. A continuing theme in the discussions throughout the book is how best to treat nicotine addiction, given that many smokers would like to stop smoking but are unable to do so because of their addiction. This book will be of great value to all psychologists and psychiatrists working on addiction, specifically to nicotine but also to other compounds and behaviours. It will also be of interest to neuroscientists and pharmacologists working on nicotine receptors and the brain pathways involved in dependence, as well as to biochemists, molecular biologist and to public health officials.
