Ascaris infections remain major global public health problems despite the wide availability of cheap, effective anthelminthic drugs. An improved understanding of host susceptibility to Ascaris infection may suggest new approaches for targeting available drugs more effectively, or may suggest novel targets for drug development efforts. This chapter explores our current understanding of the underlying genetic architecture of susceptibility to Ascaris infection. The past and potential future uses of different types of genetic approaches, from quantitative genetic studies of heritability, to gene localization, to sequencing of functional variants, are explored. The field of human complex disease genetics is moving rapidly as a result of both technological and theoretical advances. State-of-the-art genetic techniques promise to yield new insights which will dramatically improve our understanding of the determinants of differential host susceptibility to Ascaris infection.
The rise of the multi-billion dollar ancestry testing industry points to one immutable truth about us as human beings: we want to know where we come from and who our ancestors were. John H. Relethford and Deborah A. Bolnick explore this topic and many more in this second edition of Reflections of Our Past. Where did modern humans come from and how important are the biological differences among us? Are we descended from Neandertals? How should we understand the connections between genetic ancestry, race, and identity? Were Native Americans the first to inhabit the Americas? Can we see evidence of the Viking invasions of Ireland a millennium ago even in the Irish of today? Through engaging examination of issues such as these, and using non-technical language, Reflections of Our Past shows how anthropologists use genetic information to suggest answers to fundamental questions about human history. By looking at genetic variation in the world today and in the past, we can reconstruct the recent and remote events and processes that have created the variation we see, providing a fascinating reflection of our genetic past.
A long-awaited book from developmental disorders expert John Morton, Understanding Developmental Disorders: A Causal Modelling Approach makes sense of the many competing theories about what can go wrong with early brain development, causing a child to develop outside the normal range. Based on the idea that understanding developmental disorders requires us to talk about biological, cognitive, behavioral and environmental factors, and to talk about causal relationships among these elements. Explains what causal modelling is and how to do it. Compares different theories about particular developmental disorders using causal modelling. Will have a profound impact on research in the fields of psychology, neuroscience and medicine.
Though we have other distinguishing characteristics (walking on two legs, for instance, and relative hairlessness), the brain and the behavior it produces are what truly set us apart from the other apes and primates. And how this three-pound organ composed of water, fat, and protein turned a mammal species into the dominant animal on earth today is the story John S. Allen seeks to tell. Adopting what he calls a “bottom-up” approach to the evolution of human behavior, Allen considers the brain as a biological organ; a collection of genes, cells, and tissues that grows, eats, and ages, and is subject to the direct effects of natural selection and the phylogenetic constraints of its ancestry. An exploration of the evolution of this critical organ based on recent work in paleoanthropology, brain anatomy and neuroimaging, molecular genetics, life history theory, and related fields, his book shows us the brain as a product of the contexts in which it evolved: phylogenetic, somatic, genetic, ecological, demographic, and ultimately, cultural-linguistic. Throughout, Allen focuses on the foundations of brain evolution rather than the evolution of behavior or cognition. This perspective demonstrates how, just as some aspects of our behavior emerge in unexpected ways from the development of certain cognitive capacities, a more nuanced understanding of behavioral evolution might develop from a clearer picture of brain evolution.
This is the second edition of a monograph on generalized linear models with random effects that extends the classic work of McCullagh and Nelder. It has been thoroughly updated, with around 80 pages added, including new material on the extended likelihood approach that strengthens the theoretical basis of the methodology, new developments in variable selection and multiple testing, and new examples and applications. It includes an R package for all the methods and examples that supplement the book.
With the increasing incidence of Type 2 diabetes in the adult population and the realization that this is a vascular disease and a major coronary risk factor, Professor Betteridge has chosen fifty diabetologists to contribute a case which has had an effect on their clinical practice. Both Types 1 and 2 diabetes are included, along with other forms of diabetes, eg gestational. Each case is presented in the same format. The various cases are informative and educational and should provide the reader with a sounder knowledge of patient and disease types.
Where did modern humans come from and how important are the biological differences among us? Are we descended from Neanderthals? How many races of people are there? Were Native Americans the first settlers of the New World? How can we tell if Thomas Jefferson had a child with Sally Hemings? Through an engaging examination of issues such as these, and using non-technical language, Reflections of Our Past shows how anthropologists use genetic information to test theories and define possible answers to fundamental questions in human history. By looking at genetic variation in the world today, we can reconstruct the recent and remote events and processes that created the variation we see, providing a fascinating reflection of our genetic past. Reflections of Our Pastis a W. W. Howells Book Prize Winner and Choice Outstanding Academic Title.

The genetic correlates of neuropsychiatric disorders are now known, but none have come close to explaining the great variety of human psychiatric illnesses. This volume, written by a neuropsychiatrist and an evolutionary biologist, offers a new paradigm for understanding these disorders. Proposing that neuronal pathways which underlie neuropsychiatric conditions mirror unique human capabilities, the authors iterate a new paradigm by which to understand human psychiatric illnesses. Human capabilities such as theory of mind, language, and complex social behaviors are explored through their histological, neuroanatomical and functional brain imaging correlates. The capacity for representation, the authors suggest, is central to the understanding of the human brain. Brain structures such as the frontal pole, temporal pole, and fronto-insular cortex are highly developed in humans and are associated with representation. Other brain regions, including the dorsal anterior cingulate cortex, auditory cortex, and hippocampus, are linked with directed effort while the ventral anterior cingulate cortex, orbital frontal cortex, and amygdala are related to emotional encoding. Both networks interact with representional regions and the dorsolateral prefrontal cortex. Conditions like schizophrenia may result, in part, from a failure of the networks associated with directed effort while bipolar disorders may arise from a failure of networks associated with emotional encoding. Similarly, autism may result from a failure of representational brain regions; frontotemporal dementia may be associated with failure of several discrete networks in later life. From this perspective, neuropsychiatric disorders are selective failures of brain networks involved in the integration of cognition, affect and perception. A better understanding of these brain networks will assist psychiatric and mental health researchers in the search for environmental factors and genetic correlates of disorders as well as aid in the development of more effective treatments for these diseases. This volume will be of interest to psychiatrists, neurologists, psychologists, biologists, and imaging scientists--anyone who has ever wondered what makes the human brain human.

A complete guide to the role of high-density lipoproteins (HDL) in new and emerging therapies With high-density lipoproteins (HDL) playing an increasing role in cardiovascular disease prevention, there is a growing need for an in-depth look at HDL and its clinical value. This book summarizes the current state of knowledge in the field, providing for the first time a comprehensive, systematic, stylistically coherent, and up-to-date review of the composition, structure, heterogeneity, metabolism, epidemiology, genetics, and function of HDL. Divided into three main parts, High-Density Lipoproteins first examines normal HDL particles, then describes defective HDL, and finally addresses the therapeutic normalization of subnormal levels and defective biological activities of this lipoprotein class. The book highlights the functional properties of HDL, which are relevant to the pathophysiology of atherosclerosis and thrombosis, and discusses the compositional and metabolic heterogeneity of HDL particles. Readers will come away with a clear understanding of the role of HDL in biological processes, the potential value of functional HDL as a therapeutic target, and how current and emerging therapies are poised to influence the treatment of heart disease in the future.
John Bachman (1790-1874) was an internationally renowned naturalist and a prominent Lutheran minister. This is the first collection of his writings, containing selections from his three major books, his letters, and his articles on plants and animals, education, religion, agriculture, and the human species. Bachman was the leading authority on North American mammals. He was responsible for the descriptions of the 147 mammal species included in Viviparous Quadrupeds of North America, a massive work produced in collaboration with John James Audubon. Bachman relied entirely on scientific evidence in his work and was exceptional among his fellow naturalists for studying the whole of natural history. Bachman also relied on scientific evidence in his Doctrine of the Unity of the Human Race. He showed that human beings constitute a single species that developed as varieties equivalent to the varieties of domesticated animals. In this work, perhaps his most significant accomplishment, Bachman stood nearly alone in challenging the polygenetic views of Louis Agassiz and others that white and black people descended from different progenitors. Bachman was also an important figure in the establishment of Lutheranism in the Southeast. He wrote the first American monograph on the doctrines of Martin Luther and the history of the Reformation. Bachman served for fifty-six years as minister of St. John's Lutheran Church in Charleston, South Carolina, and was one of the founders of Newberry College.
