Peripheral Visions: Learning Along the Way

by Mary C. Bateson

Mary Catherine Bateson, author of Composing a Life, is our guide on a fascinating intellectual exploration of lifetime learning from experience and encountering the unfamiliar. Peripheral Visions begins with a sacrifice in a Persian garden, moving on to a Philippine village and then to the Sinai desert, and concludes with a description of a tour bus full of Tibetan monks. Bateson's reflections bring theses narratives homes, proposing surprising new vision of our own diverse and changing society and offering us the courage to participate even as we are still learning.

Periphery: How Your Nervous System Predicts and Protects against Disease

by Moses V. Chao

A leading neuroscientist argues that the peripheral nervous system, long understood to play a key role in regulating basic bodily functions, also signals the onset of illness.The central nervous system, consisting of the brain and the spinal cord, has long been considered the command center of the body. Yet outside the central nervous system, an elaborate network of nerve cells and fibers extends throughout our bodies, transmitting messages between the brain and other organs. The peripheral nervous system, as it’s known, regulates such vital functions as heart rate, digestion, and perspiration and enables us to experience the barrage of sounds, tastes, smells, and other sensory information that surrounds us. But beyond these crucial roles, the peripheral nervous system might do even more: it might warn us of diseases in our future.As Moses Chao argues in Periphery, from Parkinson’s disease to autism to dementia, many neurological conditions emerge not in the brain but rather within the peripheral nervous system, in the dense network of nerves that wrap around the gastrointestinal tract. What’s more, dysfunctions of the peripheral nervous system can signal the onset of disease decades before symptoms like tremor or memory loss occur. Fortunately, unlike nerves in the brain and spinal cord, peripheral nerves can heal and regenerate in response to injury and aging. The therapeutic implications are remarkable. Chao shows how, with a better understanding of the peripheral nervous system, we could not only predict and treat neurological diseases long before their onset, but possibly prevent them altogether.Full of new ideas and bold interpretations of the latest data, Periphery opens exciting avenues for medical research while deepening our understanding of a crucial yet underappreciated biological system.

Permafrost Ecosystems

by Akira Osawa Olga A. Zyryanova Takuya Kajimoto Yojiro Matsuura Ross W. Wein

Drawing from a decade-long collaboration between Japan and Russia, this important volume presents the first major synthesis of current knowledge on the ecophysiology of the coniferous forests growing on permafrost at high latitudes. It presents ecological data for a region long inaccessible to most scientists, and raises important questions about the global carbon balance as these systems are affected by the changing climate. Making up around 20% of the entire boreal forests of the northern hemisphere, these 'permafrost forest ecosystems' are subject to particular constraints in terms of temperature, nutrient availability, and root space, creating exceptional ecosystem characteristics not known elsewhere. This authoritative text explores their diversity, structure, dynamics and physiology. It provides a comparison of these forests in relation to boreal forests elsewhere, and concludes with an assessment of the potential responses of this unique biome to climate change. The book will be invaluable to advanced students and researchers interested in boreal vegetation, forest ecology, silviculture and forest soils, as well as to researchers into climate change and the global carbon balance.

Permeable Reactive Barrier: Sustainable Groundwater Remediation (Advances in Trace Elements in the Environment #1)

by Ravi Naidu

Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.

Permutation Testing for Isotonic Inference on Association Studies in Genetics

by Rosa Arboretti Livio Corain Luigi Salmaso Dario Mazzaro

The purpose of this book is to illustrate a new statistical approach to test allelic association and genotype-specific effects in the genetic study of diseases. There are some parametric and non-parametric methods available for this purpose. We deal with population-based association studies, but comparisons with other methods will also be drawn, analysing the advantages and disadvantages of each one, particularly with regard to power properties with small sample sizes. In this framework we will work out some nonparametric statistical permutation tests and likelihood-based tests to perform case-control analyses to study allelic association between marker, disease-gene and environmental factors. Permutation tests, in particular, will be extended to multivariate and more complex studies, where we deal with several genes and several alleles together. Furthermore, we show simulations under different assumptions on the genetic model and analyse real data sets by simply studying one locus with the permutation test.

Peroxiporins: Redox Signal Mediators In and Between Cells (Oxidative Stress and Disease #50)

by Iria Medraño-Fernandez Gerd Patrick Bienert Roberto Sitia

To produce energy, aerobic organisms transform oxygen molecules into water. This reductive mechanism yields toxic radical intermediates, collectively known as reactive oxygen species (ROS). Paradoxically, these physiological processes entail the production of potentially damaging species. Evolution has turned this apparent disadvantage into an opportunity for transmitting information. As a result, redox signaling within the cell is an efficient exquisitely organized process. A key element for its regulation is the physical separation of sources and targets into different cell compartments. Peroxiporins, H2O2 transporting proteins spanning biological membranes, distribute the signal from emitters to receptors. Thus, these channels are strategically situated in the thin line between life and death, guaranteeing adequate but safe signaling. Key Features: - Provides a brief history of the discovery and characterization of peroxiporins- Reviews key findings on hydrogen peroxide transport across biological membranes- Discusses the cartography of redox signaling in crowded cells- Includes lavish illustrations and comprehensive images to facilitate teaching- Highlights recent findings, outstanding controversies and open questions

Peroxisomes and their Key Role in Cellular Signaling and Metabolism

by Luis A. del Río

Peroxisomes are a class of ubiquitous and dynamic single membrane-bounded cell organelles, devoid of DNA, with an essentially oxidative type of metabolism. In recent years it has become increasingly clear that peroxisomes are involved in a range of important cellular functions in almost all eukaryotic cells. In higher eukaryotes, including humans, peroxisomes catalyze ether phospholipids biosynthesis, fatty acid alpha-oxidation, glyoxylate detoxification, etc, and in humans peroxisomes are associated with several important genetic diseases. In plants, peroxisomes carry out the fatty acid beta-oxidation, photorespiration, metabolism of ROS, RNS and RSS, photomorphogenesis, biosynthesis of phytohormones, senescence, and defence against pathogens and herbivores. In recent years it has been postulated a possible contribution of peroxisomes to cellular signaling. In this volume an updated view of the capacity and function of peroxisomes from human, animal, fungal and plant origin as cell generators of different signal molecules involved in distinct processes of high physiological importance is presented.

The Perpetual Now: A Story of Amnesia, Memory, and Love

by Michael D. Lemonick

In the aftermath of a shattering illness, Lonni Sue Johnson lives in a "perpetual now," where she has almost no memories of the past and a nearly complete inability to form new ones. The Perpetual Now is the moving story of this exceptional woman, and the groundbreaking revelations about memory, learning, and consciousness her unique case has uncovered. Lonni Sue Johnson was a renowned artist who regularly produced covers for The New Yorker, a gifted musician, a skilled amateur pilot, and a joyful presence to all who knew her. But in late 2007, she contracted encephalitis. The disease burned through her hippocampus like wildfire, leaving her severely amnesic, living in a present that rarely progresses beyond ten to fifteen minutes. Remarkably, she still retains much of the intellect and artistic skills from her previous life, but it's not at all clear how closely her consciousness resembles yours or mine. As such, Lonni Sue's story has become part of a much larger scientific narrative—one that is currently challenging traditional wisdom about how human memory and awareness are stored in the brain. In this probing, compassionate, and illuminating book, award-winning science journalist Michael D. Lemonick uses the unique drama of Lonni Sue Johnson's day-to-day life to give us a nuanced and intimate understanding of the science that lies at the very heart of human nature.
