In The Intelligent Movement Machine: An Ethological Perspective on the Primate Motor System, Michael Graziano offers a fundamentally new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex pattern, explaining the otherwise inexplicable details of the motor cortex organization. This clearly written book book includes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to Graziano's "action map" view. Though focused on the motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social beahvior such as smiling and laughing, to the mysterious link between movement disorders and autism. This book is written for a general audience, and should be of interest to experts, students, and the scientific lay.
How do you keep track of basic information on the proteins you work
with? Where do you find details of their physicochemical
properties, amino acid sequences, gene organization? Are you tired
of scanning review articles, primary papers and databases to locate
that elusive fact?
DNA sequence specificity is a sub-specialty in the general area of
molecular recognition. This area includes macromolecular-molecular
interactions (e.g., protein-DNA), oligomer-DNA interacitons (e.g.,
triple strands), and ligand-DNA interactions (e.g., drug-DNA). It
is this latter group of DNA sequence specificity interactions that
is the subject of Volumes 1 and 2 of "Advances in DNA Sequence
Specific Agents." As was the case for Volume 1, Part A also covers
methodology, but in Volume 2 we include calorimetric titrations,
molecular modeling, X-ray crystallographic and NMR structural
studies, and transcriptional assays. Part B also follows the same
format as Volume 1 and describes the sequence specificities and
covalent and noncovalent interactions of small ligands with
DNA.
Research on the cytochrome P450 family of genes has traditionally
been dominated by forms participating in drug metabolism. This has
occurred in spite of early discovery of steroid hydroxy lase P450
cytochromes in the adrenal gland. More recently, contributions on
the characterization and regulation of P450 cytochromes involved in
biosynthetic reactions have been found at the international
meetings on cytochrome P450 and in the several books on the field.
Key recognition that P450 cytochromes should be recognized in a
physiological context was provided by an international meeting in
Jerusalem in 1991 and the subsequent publication of the proceedings
in the "Journal of Steroid Biochemistry and Molecular Biology" (43,
number 8, 92). Like this meeting, this book seeks to place equal
weight on the physiological processes that are controlled by the
products of reactions at usually very selective cytochrome P450
forms. Each of the authors was asked to discuss the molecular
regulation of these P450 forms. Each of the authors was asked to
discuss the molecular regulation of these P450 forms in the light
of these physiological processes. In some cases the physiological
role of the cytochrome P450 and even the natural substrate are
unresolved, but a pattern of strong endocrine regulation is
indicative of a hidden function. As more and more low abundance
P450 genes are uncovered, the need to address potential
physiological activities becomes more pressing. It is almost
infinitely more difficult to identify a physiological substrate
than to clone a new form.
In Volume 18 of this well-established series, Professor
Atta-ur-Rahman again brings together the work of several of the
world's leading authorities in organic chemistry. Their
contributions demonstrate the rapid, ongoing development of this
field by illustrating many of the latest advances in synthetic
methods, total synthesis, structure determination, biosynthetic
pathways, and biological activity.
This practical book provides the detailed methodology and expert
guidance required for measuring and manipulating cytosolic ion
concentrations. In addition, the strengths, weaknesses, and
pitfalls of various techniques are presented. It is an invaluable
source for those needing an objective evaluation of current
methodologies and for those contemplating setting up such
procedures.
Gene probes, whether RNA or DNA, have played a central role in the rapid development of molecular biology. The wide variety of applications is matched by a considerable diversity in the methods used for generating probes, a complete account of which would be very difficult to make. Instead, this second volume in the series combines a selection of newer gene probe procedures with a review of the most important established methods, together with some examples of the ways in which gene probes can be applied. In doing so, the book aims to act not only as an introductory manual for newcomers to the field, but also as a means of broadening the horizons of existing researchers.
Recent advances in genetic engineering and in the chemistry and biochemistry of fruit and vegetables have radically changed our understanding of the mechanisms underlying these processes, and the potential for modification of the products themselves. This is the first book to examine these topics and address the role of fresh fruits and vegetables in a healthy diet and the prevention of cancer and coronary diseases. The main focus is on the secondary metabolites which are responsible for quality characteristics including color, aroma, and flavor, and their nutritional importance and role in the prevention of cancer and cardiovascular diseases. The book also explores how the post-harvest technological treatments to which these commodities are submitted can cause changes in secondary metabolism, with consequences for the quality of the product.
A timely book for DNA researchers, Automated DNA Sequencing and
Analysis reviews and assesses the state of the art of automated DNA
sequence analysis-from the construction of clone libraries to the
developmentof laboratory and community databases. It presents the
methodologies and strategies of automated DNA sequence analysis in
a way that allows them to be compared and contrasted. By taking a
broad view of the process of automated sequence analysis, the
present volume bridges the gap between the protocols supplied with
instrument and reaction kits and the finalized data presented in
the research literature. It will be an invaluable aid to both small
laboratories that are interested in taking maximum advantageof
automated sequence resources and to groups pursuing large-scale
cDNA and genomic sequencing projects.
During the past two decades international collaborative studies
have yielded extensive information on genome sequences, genome
architecture and their variations. The challenge we now face is to
understand how these variations impact structure and function of
organelles, physiological systems and phenotype. The goal of this
book is to present steps in the pathways of exploration to connect
genotype to phenotype and to consider how alterations in genomes
impact disease.
In the past, the stability of milk and milk products was the primary consideration, but this is no longer the principal objective due to the evolution of modern sanitary practices as well as pasteurization. Today, the manufacture of dairy products of consistently good flavor and texture is crucial. In previous flavor studies, researchers identified hundreds of volatile compounds, with little or no attention paid to their sensory contribution to overall flavor of dairy products. The availability of powerful chromatographic separation techniques like high resolution gas chromatography in combination with mass spectrometry and olfactory detection ports have revolutionized the work on characterization of dairy flavor. This along with recent developments in sensory methods and our increased knowledge about the genomics of diary culture organisms have allowed great advancements in our understanding of dairy flavor chemistry. Flavor of Dairy Products covers the evolution of dairy flavor research and presents updated information in the areas of instrumental analysis, biochemistry, processing and shelf-life issues related to the flavor of dairy products.
Flora of North America brings together for the first time ever in a
concise and easy to understand format information on all of the
plants growing spontaneously in North America north of Mexico.
Volume 24 of Flora North America is one of two volumes on grasses
to be published in this series (Volume 25, though it follows
sequentially, was published in 2003). Together they will provide a
comprehensive, authoritative, illustrated account of this important
group of plants. Most of the species treated are either native to
North America north of Mexico or are introduced species that are
now established in the region, but there are many that do not fit
into these categories. Among the additional species are several
that the USDA has identified as major weed threats; and others that
are known only as cultivated plants, some being cultivated for
their ornamental value, others as sources for human food or animal
forage. For instance, volume 24 includes such ecologically
important genera as Elymus (wheatgrasses), Poa (bluegrasses), and
Festuca (fescues), economically important species such as Triticum
(wheat), Hordeum (barley), Oryza (rice), and Zizania (wild rice),
several ornamental species, including some bamboos, and noxious
weeds such as Elymus repens (quackgrass), and Bromus tectorum
(cheatgrass).
The history of life is a nearly four billion year old story of transformative change. This change ranges from dramatic macroscopic innovations such as the evolution of wings or eyes, to a myriad of molecular changes that form the basis of macroscopic innovations. We are familiar with many examples of innovations (qualitatively new phenotypes that can provide a critical advantage) but have no systematic understanding of the principles that allow organisms to innovate. This book proposes several such principles as the basis of a theory of innovation, integrating recent knowledge about complex molecular phenotypes with more traditional Darwinian thinking. Central to the book are genotype networks: vast sets of connected genotypes that exist in metabolism and regulatory circuitry, as well as in protein and RNA molecules. The theory can successfully unify innovations that occur at different levels of organization. It captures known features of biological innovation, including the fact that many innovations occur multiple times independently, and that they combine existing parts of a system to new purposes. It also argues that environmental change is important to create biological systems that are both complex and robust, and shows how such robustness can facilitate innovation. Beyond that, the theory can reconcile neutralism and selectionism, as well as explain the role of phenotypic plasticity, gene duplication, recombination, and cryptic variation in innovation. Finally, its principles can be applied to technological innovation, and thus open to human engineering endeavours the powerful principles that have allowed life's spectacular success.
Ethicists and psychologists have become increasingly interested in the development of virtue in recent years, approaching the topic from the perspectives of virtue ethics and developmental psychology respectively. Such interest in virtue development has spread beyond academia, as teachers and parents have increasingly striven to cultivate virtue as part of education and child-rearing. Looking at these parallel trends in the study and practice of virtue development, the essays in this volume explore such questions as: How can philosophical work on virtue development inform psychological work on it, and vice versa? How should we understand virtue as a dimension of human personality? What is the developmental foundation of virtue? What are the evolutionary aspects of virtue and its development? How is virtue fostered? How is virtue exemplified in behavior and action? How is our conception of virtue influenced by context and by developmental and social experiences? What are the tensions, impediments and prospects for an integrative field of virtue study? Rather than centering on each discipline, the essays in this volume are orgnaized around themes and engage each other in a broader dialogue. The volume begins with an introductory essay from the editors that explains the full range of philosophical and empirical issues that have surrounded the notion of virtue in recent years.
In this book, Chris Eliasmith presents a new approach to understanding the neural implementation of cognition in a way that is centrally driven by biological considerations. He calls the general architecture that results from the application of this approach the Semantic Pointer Architecture (SPA), based on the Semantic Pointer Hypothesis. According to this hypothesis, higher-level cognitive functions in biological systems are made possible by semantic pointers. These pointers are neural representations that carry partial semantic content and can be built up into the complex representational structures necessary to support cognition. The SPA architecture demonstrates how neural systems generate, compose, and control the flow of semantics pointers. Eliasmith describes in detail the theory and empirical evidence supporting the SPA, and presents several examples of its application to cognitive modeling, covering the generation of semantic pointers from visual data, the application of semantic pointers for motor control, and most important, the use of semantic pointers for representation of language-like structures, cognitive control, syntactic generalization, learning of new cognitive strategies, and language-based reasoning. He agues that the SPA provides an alternative to the dominant paradigms in cognitive science, including symbolicism, connectionism, and dynamicism.
We are becoming increasingly aware of the overwhelming pollution of our limited water resources on this planet. And while many contaminants originate from Mother Earth, most water pollution comes as a direct result of anthropogenic activities. This problem has become so immense that it threatens the future of all humanity. If effective measures to reduce and/or remediate water pollution and its sources are not found, it is estimated by UN that 2.7 billion people will face water shortage by 2025 as opposed to 1.2 billion people who do not have access to clean drinking water now. Therefore, development of novel green technologies to address this major problem represents a priority of the highest importance. This book discusses green chemistry and other novel solutions to the water pollution problems which includes some interesting applications of nanoparticles. Novel Solutions to Water Pollution is a useful and informative text for those engaged in issues of water quality and water pollution remediation at operational, administrative, academic, or regulatory levels.

Rethinking Thought takes readers into the minds of 30 creative thinkers to show how greatly the experience of thought can vary. It is dedicated to anyone who has ever been told, "You're not thinking!", because his or her way of thinking differs so much from a spouse's, employer's, or teacher's. The book focuses on individual experiences with visual mental images and verbal language that are used in planning, problem-solving, reflecting, remembering, and forging new ideas. It approaches the question of what thinking is by analyzing variations in the way thinking feels. Written by neuroscientist-turned-literary scholar Laura Otis, Rethinking Thought juxtaposes creative thinkers' insights with recent neuroscientific discoveries about visual mental imagery, verbal language, and thought. Presenting the results of new, interview-based research, it offers verbal portraits of novelist Salman Rushdie, engineer Temple Grandin, American Poet Laureate Natasha Trethewey, and Nobel prize-winning biologist Elizabeth Blackburn. It also depicts the unique mental worlds of two award-winning painters, a flamenco dancer, a game designer, a cartoonist, a lawyer-novelist, a theoretical physicist, and a creator of multi-agent software. Treating scientists and artists with equal respect, it creates a dialogue in which neuroscientific findings and the introspections of creative thinkers engage each other as equal partners. The interviews presented in this book indicate that many creative people enter fields requiring skills that don't come naturally. Instead, they choose professions that demand the hardest work and the greatest mental growth. Instead of classifying people as "visual" or "verbal," educators and managers need to consider how thinkers combine visual and verbal skills and how those abilities can be further developed. By showing how greatly individual experiences of thought can vary, this book aims to help readers in all professions better understand and respect the diverse people with whom they work.
The technique of in situ hybridization is now vital to molecular biologists and their understanding of the pathophysiology of cellular functions. This practical guide covers all aspects of in situ hybridization, describing: practical procedures and protocols; the scientific background; areas of application; and the limitations of the technology. This edition has been completely rewritten to take into acocunt the many advances in the seven years since its initial publication.
Consumers, regulators, and the food industry increasingly require that foods comply not only with label descriptions of food content, but also with information regarding the food's origin. For example, the wine industry has a long history of labeling wines based on varietal, regional, or age (vintage)-related properties. However, regulatory agencies are now beginning to require methods to confirm this label information. Food retailers are also facing voluntary or mandatory labeling requirements that will indicate regional or country-of-origin, species and/or varietal information. As a result, development of reliable analytical methods to confirm the authenticity of the label information is needed. This book presents the latest research on food and wine authentication. The chapters are authored by leading international scientists whose research focuses on the development and application of analytical methodologies used for the authentication of food and beverages.
Measuring metabolic rates is central to important questions in many
areas of scientific research. Unfortunately these measurements are
anything but straightforward, and numerous pitfalls await the
novice and even the experienced investigator.
The human pathogens Neisseria meningitidis and Neisseria gonorrhoeae are exquisitely adapted to life within the human mucosa, their only natural niche. N. meningitidis is the causative agent of rapidly transmissible meningitis and septic shock. Vaccines developed to control this pathogen can be rendered ineffective by the pathogen's ability to undergo antigenic variation. In contrast, there are no current vaccination prospects for N. gonorrhoeae, the causative agent of sexually transmitted gonorrhoea. Historically, infections caused by N. gonorrhoeae were treated with antibiotics. However, the recent advent of new strains with resistance to all known antibiotics is causing such treatment regimes to fail, necessitating the need for new and more effective control strategies. In this book, leading Neisseria authorities review the most important research on pathogenic Neisseria to provide a timely overview of the field. The topics covered include: the link between pathogenesis and important metabolic pathways * vaccine development * antibiotic resistance * transcriptomics of regulatory networks * regulatory small RNAs * interactions with neutrophils * advances in humanized mouse models. An essential guide for research scientists, advanced students, clinicians, and other professionals working with Neisseria, the book is a recommended text for all microbiology libraries.
Primary sexual traits, those structures and processes directly
involved in reproduction, are some of the most diverse,
specialized, and bizarre in the animal kingdom. Moreover,
reproductive traits are often species-specific, suggesting that
they evolved very rapidly. This diversity, long the province of
taxonomists, has recently attracted broader interest from
evolutionary biologists, especially those interested in sexual
selection and the evolution of reproductive strategies. |
