For the past decade or more, much of cell biology research has been focused on determining the key molecules involved in different cellular processes, an analytical problem that has been amenable to biochemical and genetic approaches. Now, we face an integrative problem of understanding how all of these molecules work together to produce living cells, a challenge that requires using quantitative approaches to model the complex interactions within a cell, and testing those models with careful quantitative measurements. This book is an introductory overview of the various approaches, methods, techniques, and models employed in quantitative cell biology, which are reviewed in greater detail in the other volumes in this e-book series. Particular emphasis is placed on the goals and purpose of quantitative analysis and modeling, and the special challenges that cell biology holds for understanding life at the physical level.
This book offers a comprehensive overview of Alexander disease, a rare and devastating neurological disorder that often affects the white matter of the brain and spinal cord. Its distinctive neuropathology consists of abundant Rosenthal fibers within astrocytes (one of the four major cell types of the central nervous system). Nearly all cases are caused by variants in the gene encoding the intermediate filament protein GFAP, but how these changes in GFAP lead to the widespread manifestations of disease is poorly understood. Astrocytes, while discovered over a century ago, are themselves still much of a mystery. They exhibit considerable diversity, defy precise definition, and yet actively regulate many aspects of nervous system functioning. We also have incomplete understanding of Rosenthal fibers, odd structures that contain GFAP as just one of many components. Whether they are toxic or protective is unknown. Moreover, Rosenthal fibers are not absolutely unique to Alexander disease, and are seen sporadically in a wide variety of other conditions, including brain tumors and multiple sclerosis. GFAP is the third unknown. It is an ancient protein, arising early in the evolution of vertebrates, but its role in normal biology is still a matter of debate. Yet Alexander disease shows, without a doubt, that changing just a single of its 432 amino acids can lead to catastrophe, not just in the astrocytes where GFAP is produced but also in the other cells with which astrocytes interact. Despite all of the unknowns, much has been learned in the past 20 years, and it is time to share this knowledge. This book is intended for recently diagnosed patients and families, as well as non-specialist researchers interested in this neurological disease. It covers historical origins, the state of current knowledge, and prospects for what lies ahead, with citations to the primary literature given throughout.
Africa is home to an amazing array of animals, including the world's most diverse assortment of large mammals. These include the world's largest terrestrial mammal, the African elephant, which still roams great swathes of the continent alongside a host of hooved mammals such as hippopotamuses, giraffes, rhinoceroses, and zebras. African Ark: Mammals, Landscape and the Ecology of a Continent tells the story of where these mammals have come from and how they have interacted to create the richly varied landscape that makes up Africa as we know it today. It also highlights small mammals, such as rodents and bats, which are often overlooked by both naturalists and zoologists in favour of their larger cousins. African Ark explains the processes through which species and population groups are formed and how these fluctuate over time. It explores the impact of megafauna on the environment and the important roles they play in shaping the landscape. In this way, mammals such as elephants and rhinoceros support countless plant communities and the habitats of many smaller animals. The book brings in a human perspective as well as a conservation angle in its assessment of the interaction of African mammals with the people who live alongside them. African Ark is at once scientifically rigorous - drawing on the contributions of numerous zoologists, ecologists and conservationists - and an engaging read for anyone dedicated to the understanding of Africa and its wildlife.
Successes and Challenges of NK Immunotherapy: Increasing Anti-tumor Efficacy describes the unique therapeutic applications of NK cells to fight cancers and eliminate the bulk and subset of cancer stem cells responsible for metastasis, relapse and recurrences. The book provides information on the development, engineering, mechanisms of action, response to various preclinical models, and applications in various clinical trials. Sections cover the development of highly engineered cytotoxic NK cells, their mechanisms of action, preclinical and clinical applications, the development and application of CAR-NK cells, and new NK-drug conjugates, also emphasizing that activated NK cells can target and kill highly resistant cancer stem cells. Written by the leading experts on NK immunotherapy worldwide, this is a valuable resource for researchers, clinicians and members of the biomedical field who are interested in understanding novel and efficient therapies to fight cancers.
Epidemiology of Brain and Spinal Tumors provides a single volume resource on imaging methods and neuroepidemiology of both brain and spinal tumors. The book covers a variety of imaging techniques, including computed tomography (CT), MRI, positron emission tomography (PET), and other laboratory tests used in diagnosis and treatment. Detailed epidemiology, various imaging methods, and clinical considerations of tumors of the CNS make this an ideal reference for users who will also find diverse information about structures and functions, cytology, epidemiology (including molecular epidemiology), diagnosis and treatment. This book is appropriate for neuroscience researchers, medical professionals and anyone interested in a complete guide to visualizing and understanding CNS tumors.
The brains of males and females, men and women, are different, that is a fact. What is debated is how different and how important are those differences. Sex differences in the brain are determined by genetics, hormones, and experience, which in humans includes culture, society, and parental and peer expectations. The importance of nonbiological variables to sex differences in humans is paramount, making it difficult if not impossible to parse out those contributions that are truly biological. The study of animals provides us the opportunity to understand the magnitude and scope of biologically based sex differences in the brain, and understanding the cellular mechanisms provides us insight into novel sources of brain plasticity. Many sex differences are established during a developmental sensitive window by differences in the hormonal milieu of males versus females. The neonatal testis produces large amounts of testosterone which gains access to the brain and is further metabolized into active androgens and estrogens which modify brain development. Major parameters that are influenced by hormones include neurogenesis, cell death, neurochemical phenotype, axonal and dendritic growth, and synaptogenesis. Variance in these parameters results in sex differences in the size of particular brain regions, the projections between brain regions, and the number and type of synapses within particular brain regions. The cellular mechanisms are both region and endpoint specific and invoke many surprising systems such as prostaglandins, endocannabinoids, and cell death proteins. Epigenetic modifications to the genome both establish and maintain sex differences in the brain and behavior. By understanding when, why, and how sex differences in the brain are established, we may also learn the source of strong gender biases in the relative risk and severity of numerous neurological diseases and disorders of mental health. Boys are much more likely to be diagnosed with autism spectrum or attention and hyperactivity disorders, as well as speech and language deficits, compared to girls. By contrast, women are more likely to suffer from affective disorders, such as depression, anxiety, compulsion, and eating disorders and more likely to experience autoimmune and neurodegenerative disorders. Schizophrenia with an early onset is more common in males but a late-onset version is markedly more frequent in females. Male biased disorders have origins in development while female biased disorders are almost exclusively post-puberty. This remarkable shift in disease risk demands our attention. Novel insights into the biological origins of disease are also gained by comparing and contrasting the same processes in different sexes.
The Oxford Handbook of Metamemory investigates the human ability to evaluate and control learning and information retrieval processes. Each chapter in this authoritative guide highlights a different facet of metamemory research, including classical metamemory judgments; applications of metamemory research to the classroom and courtroom; and cutting-edge perspectives on continuing debates and theory. Chapters also provide broad historical overviews of each research area and discussions of promising directions for future research. The breadth and depth of coverage on offer in this Handbook make it ideal for seminars on metamemory or metacognition. It would also be a valuable supplement for advanced courses on cognitive psychology, of use especially to graduate students and more seasoned researchers who are interested in exploring metamemory for the first time.
Tumor Microenvironment Regulation of Tumor Expansion is a practical guide to understand and perform research on tumor microenvironments, and to support related clinical decisions. Tumor progression is linked to an imbalance between positive and negative regulators, and mainly depends on the release of specific growth factors by inflammatory or neoplastic cells. Inflammatory infiltrate contributes to tumor progression and the metastatic process, and there are many reports of associations between tumor inflammatory infiltrate, progression, and prognosis. Understanding different contexts of organs is a key factor in improving treatment outcome, especially in new therapeutic treatments targeting components of the tumor microenvironment. This book is a valuable resource for cancer researchers, clinicians, graduate students, and scientists in many biomedical fields who are interested in the complex relationship between the tumor microenvironment and its context in specific organs.
This title includes a number of Open Access chapters. This collection presents a broad selection of recent research on analytical chemistry, including methods of determination and analysis as applied to plants, pharmaceuticals, foods, proteins, and more. Analytical chemistry is the study of what chemicals are present and in what amount in natural and artificial materials. Because these understandings are fundamental in just about every chemical inquiry, analytical chemistry is used to obtain information, ensure safety, and solve problems in many different chemical areas, and is essential in both theoretical and applied chemistry. Analytical chemistry is driven by new and improved instrumentation.
In The Mind within the Brain, David Redish brings together cutting edge research in psychology, robotics, economics, neuroscience, and the new fields of neuroeconomics and computational psychiatry, to offer a unified theory of human decision-making. Most importantly, Redish shows how vulnerabilities, or "failure-modes," in the decision-making system can lead to serious dysfunctions, such as irrational behavior, addictions, problem gambling, and PTSD. Told with verve and humor in an easily readable style, Redish makes these difficult concepts understandable. Ranging widely from the surprising roles of emotion, habit, and narrative in decision-making, to the larger philosophical questions of how mind and brain are related, what makes us human, the nature of morality, free will, and the conundrum of robotics and consciousness, The Mind within the Brain offers fresh insight into one of the most complex aspects of human behavior.
Twin and Family Studies of Epigenetics, Volume 27, the latest release in the Translational Epigenetics series, gathers expert opinions on epigenetic twin and family study research methods, recent findings across various disease areas, and future directions. The book provides in-depth coverage of epigenetics fundamentals, twin and family epigenetic study design, and the broader role of epigenetics in answering questions on the developmental origins of health and disease. Throughout the volume, twin and family studies are employed to examine causes of epigenetic variation, the relationship between epigenetic modifications and mental illness, cancers, cardiovascular disease, diabetes, obesity, high blood pressure, and more. Emerging research methods applied in twin and family studies discussed include imaging epigenetics, exposure-specific DNA methylation changes, and unravelling time trends in epigenetic effects.
Food and water are necessary for survival, but can only be obtained via ingestive behavior (feeding, drinking, and moving). Survival thus depends on the ability of the brain to coordinate the need for water and energy with appropriate behaviors to modify their intake as necessary for homeostasis. However, the balance of these behaviors also inherently determines body weight, and imbalances contribute to the development of weight disorders, such as obesity and anorexia nervosa. The lateral hypothalamic area (LHA) of the brain is anatomically positioned to coordinate the sensation of osmotic and energy status with goal-directed ingestive behaviors necessary to maintain homeostasis and body weight, and, hence, may hold insight into the potential treatment for energy balance disorders. This volume reviews the essential role of the LHA for the control of body weight, from its historical description as a ""feeding center"" to the current view of this LHA as a cellularly heterogeneous hub that regulates multiple aspects of physiology to influence body weight. Furthermore, we evaluate how specific LHA populations coordinate certain metabolic cues and behaviors, which may guide the development of pathway-specific interventions to improve the treatment of energy balance disorders.
This is the first volume to provide a detailed introduction to some of the main areas of research and practice in the interdisciplinary field of art and neuroscience. With contributions from neuroscientists, theatre scholars and artists from seven countries, it offers a rich and rigorous array of perspectives as a springboard to further exploration. Divided into four parts, each prefaced by an expert editorial introduction, it examines: * Theatre as a space of relationships: a neurocognitive perspective * The spectator's performative experience and 'embodied theatrology' * The complexity of theatre and human cognition * Interdisciplinary perspectives on applied performance Each part includes contributions from international pioneers of interdisciplinarity in theatre scholarship, and from neuroscientists of world-renown researching the physiology of action, the mirror neuron mechanism, action perception, space perception, empathy and intersubjectivity. While illustrating the remarkable growth of interest in the performing arts for cognitive neuroscience, this volume also reveals the extraordinary richness of exchange and debate born out of different approaches to the topics.

Why a text on neuroscience and Christian formation? Simply put, we need one that represents the range of possible intersections for today and into the future. In recent years, neuroscience's various fields of study have influenced our understanding of theperson, memory, learning, development, communal interaction, and the practice of education. The book serves as an introductory textbook for Christian education/formation professors to use in Christian education or Christian formation courses at the College or Seminary level. The book is designed to provide an overview of how current research in neuroscience is impacting how we view Christian education and formation with particular attention given to faith formation, teaching, development, and worship The first four chapters discuss how neuroscience broadly influences Christian education and formation. Chapters five through eight explore how neuroscience informs specific formational practices, from personal meditation, to intercultural encounter, to congregational formation and worship. The last four chapters explore various aspects of neuroscience along developmental lines, The book also moves from conceptual overviews to more empirical studies late in the text. Each chapter of this book canalso be read and discussed individually. Each author has provided both discussion topics, suggestions for future reading within neuroscience, and discussion questions at the end of the chapter.
Human Caspases and Neuronal Apoptosis in Neurodegenerative Diseases elucidates elaborately the role of caspase enzymes implicated in the initiation of molecular events leading to neuronal apoptosis in the neurodegenerative disease. The book starts with introduction to neuropathology, neurogenetics, and epidemiology of neurodegenerative disease and illustrates the involvement of human caspases, neuronal apoptosis, apoptotic pathways, genetic polymorphisms, and several other factors and underlying mechanisms in the pathology of Alzheimer's disease, Parkinson's disease, and Huntington's disease. An important focus in all chapters is the intricate mechanisms and interplay that occur during or leading to neuron death in neurodegenerative diseases, along with disease pathobiology.
