Book Synopsis Alzheimer's Disease: Cellular and Molecular Aspects of Amyloid beta by : J. Robin Harris
Download or read book Alzheimer's Disease: Cellular and Molecular Aspects of Amyloid beta written by J. Robin Harris and published by Springer Science & Business Media. This book was released on 2004-12-17 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand Alzheimer's disease (AD) is one of the major thrusts of present-day clinical research, strongly supported by more fimdamental cellular, biochemical, immunological and structural studies. It is these latter that receive attention within this book. This compilation of 20 chapters indicates the diversity of work currently in progress and summarizes the current state of knowledge. Experienced authors who are scientifically active in their fields of study have been selected as contributors to this book, in an attempt to present a reasonably complete survey of the field. Inevitably, some exciting topics for one reason or another have not been included, for which we can only apologize. Standardization of terminology is often a problem in science, not least in the Alzheimer field; editorial effort has been made to achieve standardization between the Chapters, but some minor yet acceptable personal / author variation is still present, i. e. P-amyloid/amyloid-P; Ap42/Apl-42/APi. 42! The book commences with a broad survey of the contribution that the range of available microscopical techniques has made to the study of Alzheimer's amyloid plaques and amyloid fibrillogenesis. This chapter also serves as an Introduction to the book, since several of the topics introduced here are expanded upon in later chapters. Also, it is significant to the presence of this chapter that the initial discovery of brain plaques, by Alois Alzheimer, utilized light microscopy, a technique that continues to be extremely valuable in present-day AD research.
Download or read book Neuronal Cytoskeleton written by Hirokawa and published by CRC Press. This book was released on 1994-01-12 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the primary functions of microtubule-associated proteins (MAPs) such as MAP2 and tau in neuronal morphogenesis, as well as relationships between neuronal differentiation and the expression of neuronal intermediate filaments (nestin, alpha internexin, and neurofilament triplet proteins). It emphasizes the importance of several cytoskeletal proteins for neuronal differentiation and morphogenesis, organelle transport, and synaptic functions. The book considers the involvement of tau MAPs in the formation of paired helical filaments in Alzheimer's disease, and it examines the mechanisms of organelle transports and molecular motors such as kinesin, braindynein, and kinesin superfamily proteins. Cytoskeletal proteins involved in synaptic formation and transmitter release and new synaptic junctional-associated proteins are explored as well.
Book Synopsis Pathobiology of Alzheimer's Disease by :
Download or read book Pathobiology of Alzheimer's Disease written by and published by Elsevier. This book was released on 1995-10-17 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuroscience Perspectives provides multidisciplinary reviews of topics in one of the most diverse and rapidly advancing fields in the life sciences.Whether you are a new recruit to neuroscience, or an established expert, look to this series for 'one-stop' sources of the historical, physiological, pharmacological, biochemical, molecular biological and therapeutic aspects of chosen research areas.The last decade has seen tremendous advances in our understanding of the pathobiology of Alzheimer's disease. These will lead to the first generation of drugs aimed at prevention rather than cure. This book covers some of the most important and exciting of these advances, with chapters written by many of the leading researchers in the field.With genetic studies as a backbone to this volume many chapters are devoted to the function and regulation of amyloid b-protein precursor (APP) and apolipoprotein E (ApoE). Other chapters describe cell biological approaches helping to piece together the link between the genetic alterations and the phenotype we call Alzheimer's disease.Although APP and its proteolytic cleavage product, amyloid b-protein, do not answer all the questions, detailed research into this system has undoubtedly increased our knowledge of the pathobiology of AD and has lead to the identification of other risk factors. Understanding the role of ApoE in the pathology of Alzheimer's disease promises to open a whole new field in AD research.* * Reviews the current knowledge of the pathogenesis of Alzheimer's Disease from a clinical perspective to a genetic and cell biological perspective* A comprehensive description of the role of amyloid B-protein precursor in Alzheimer's disease.* Up-to-date research data* Clear illustrations complement the text

This book presents contemporary views on the genetic, biochemical, and immunological determinants of this disease. This book also concerns the issue of Alzheimer's disease prevention through lifestyle and physical activity. Moreover, it describes the therapies used in Alzheimer's disease to slow the progression of the disease and delay its onset. Subsequently, the authors discuss experimental and clinical trials used now and in the near future. We hope that this book will help the readers to understand the complex mechanism leading to the development of Alzheimer's disease and indicate effective ways to prevent this disorder.
Book Synopsis Magnesium in the Central Nervous System by : Robert Vink
Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

Book Synopsis Mechanisms of Cell Toxicity by : E. Edward Bittar
Download or read book Mechanisms of Cell Toxicity written by E. Edward Bittar and published by JAI Press(NY). This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular toxicology has entered a new era. No longer are we concerned only with necrotic cell death produced by severe, acute insult (often to multiple intracellular targets) leading to disruption of the cell membrane. New advances in molecular and cellular biology are allowing the dissection of mechanisms of cell death involving more subtle targets within the cell. Toxicology has been very important, not only in understanding the mechanisms, nature, and severity of toxicity and thereby helping in risk assessment, but toxicology has also played a very important role in helping to understand basic biological processes. Historically this has perhaps been most evident in the use of toxic agents to interfere with specific reactions in the body and hence help to dissect out the mechanisms of metabolic processes. For example, the use of chemical inhibitors was very important in understanding the process of oxidative phosphorylation, or the tricarboxylic acid cycle. More recent examples are seen herein where toxicology interfaces with, for example structural biology in the study of the cytoskeletal components and their interactions. Indirectly, an understanding of the mechanisms of endogenous protective systems also improves knowledge of basic cell biology. Toxic insult and manipulation of cell signalling and control mechanisms in cell growth and differentation also highlight how important the discipline of cell toxicity has been and will continue to be a major contributor to our understanding of basic issues in the biological and biomedical sciences. This book offers selected reviews of some of the principal molecular mechanisms of cell toxicity.

Download or read book Update on Dementia written by Davide Moretti and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The dementia challenge is the largest health effort of the times we live in. The whole society has to move to a realization of the significance of prioritization to make an attempt in the direction of mental health promotion and dementia risk reduction. New priorities for research are needed to go far beyond the usual goal of constructing a disease course-modifying medication. Moreover, a full empowerment and engagement of men and women living with dementia and their caregivers, overcoming stigma and discrimination should be promoted. The common efforts and the final aim will have to be the progress of a ''dementia-constructive'' world, where people with dementia can take advantage of equal opportunities."--Provided by publisher
