Current Hypotheses and Research Milestones in Alzheimer's Disease


Book Description

Almost four decades of innovative and intensive research on Alzheimer’s disease (AD) have brought major advances in our understanding of its pathogenesis, improved tools for diagnosis, and strategies for its treatment. This research has helped build a solid foundation of knowledge in the neurosciences and biological basis of AD and AD-related neurological disorders. Scientific background and insightful hypotheses are of major relevance in order to approach to an effective therapy for this devastating disease. Current Hypotheses and Research Milestones in Alzheimer's Disease contains 20 seminal chapters by authors with varying views on the neuroanatomical, neuropathological, neuropsychological, neurological, and molecular aspects of AD. These chapters grew out of “Current Hypothesis on Alzheimer’s Disease”, held in Viña del Mar, Chile, in November of 2007. Participants included the world’s leading Alzheimer’s researchers, whose work has illuminated AD investigations during the past few decades. Students, academics and medical professionals will find this text an invaluable addition to the study of this important subject.




Managing Discovery in the Life Sciences


Book Description

In this book, distinguished scholars Philip A. Rea, Mark V. Pauly, and Lawton R. Burns explore the science and management behind marketable biomedical innovations. They look at how the science actually played out through the interplay of personalities, the cultures within and between academic and corporate entities, and the significance of serendipity not as a mysterious phenomenon but one intrinsic to the successes and failures of the experimental approach. With newly aggregated data and case studies, they consider the fundamental economic underpinnings of investor-driven discovery management, not as an obstacle or deficiency as its critics would contend or as something beyond reproach as some of its proponents might claim, but as the only means by which scientists and managers can navigate the unknowable to discover new products and decide how to sell them so as to maximize the likelihood of establishing a sustainable pipeline for still more marketable biomedical innovations.




The End of Alzheimer's


Book Description

The End of Alzheimer's: The Brain and Beyond, Second Edition is the first comprehensive overview on the molecular basis of Alzheimer's outside of the brain, merging the most recent findings within the field into a single book. It aims to educate the reader on the many overlooked aspects of Alzheimer's disease that occur outside the brain. This book uniquely provides step-by-step, peer-reviewed evidence that the current research model may be misguided and that a new and emerging model is more accurate. It carefully outlines the molecular research in Alzheimer's outside the brain and argues that a more thorough, whole-body diagnosis will provide better answers about its causes and lead to new treatments. It is beneficial to researchers who need to be apprised of the emerging science on the causes of Alzheimer's, and will hopefully redirect many into new avenues of cellular research and discovery. - Comprehensive literature-based summary of the current state of molecular Alzheimer's disease research - Details the shortcomings of the prevailing model and therapeutics in development - Reviews blood-based biomarkers for Alzheimer's and their link to amyloid- and Tau-independent causes outside the brain - Describes the tissues outside the brain impacted by Alzheimer's and the underlying molecular causes - Explains the whole-body risks associated with Alzheimer's, along with concomitant measures to slow or prevent the disease - Provides a protocol to properly research, evaluate, measure, diagnose, and potentially treat Alzheimer's patients




Cognitive Neuroscience


Book Description

The fifth edition of this comprehensive text explains the key issues, concepts and clinical applications of cognitive neuroscience.




Neuroscience


Book Description

The Neuronal Doctrine recently reached its 100th year and together with the development of psychopharmacology by the middle of 20th century promoted spectacular developments in the knowledge of the biological bases of behavior. The overwhelming amount of data accumulated, forced the division of neuroscience into several subdisciplines, but this division needs to dissolve in the 21st century and focus on specific processes that involve diverse methodological and theoretical approaches. The chapters contained in this book illustrate that neuroscience converges in the search for sound answers to several questions, including the pathways followed by cells, how individuals communicate with each other, inflammation, learning and memory, the development of drug dependence, and approaches to explaining the processes that underlie two highly incapacitating chronic degenerative illnesses.




Non-fibrillar Amyloidogenic Protein Assemblies - Common Cytotoxins Underlying Degenerative Diseases


Book Description

Amyloid-forming proteins are implicated in over 30 human diseases. The proteins involved in each disease have unrelated sequences and dissimilar native structures, but they all undergo conformational alterations to form fibrillar polymers. The fibrillar assemblies accumulate progressively into disease-specific lesions in vivo. Substantial evidence suggests these lesions are the end state of aberrant protein folding whereas the actual disease-causing culprits likely are soluble, non-fibrillar assemblies preceding the aggregates. The non-fibrillar protein assemblies range from small, low-order oligomers to spherical, annular, and protofibrillar species. Oligomeric species are believed to mediate various pathogenic mechanisms that lead to cellular dysfunction, cytotoxicity, and cell loss, eventuating in disease-specific degeneration and systemic morbidity. The particular pathologies thus are determined by the afflicted cell types, organs, systems, and the proteins involved. Evidence suggests that the oligomeric species may share structural features and possibly common mechanisms of action. In many cases, the structure–function interrelationships amongst the various protein assemblies described in vitro are still elusive. Deciphering these intricate structure–function correlations will help understanding a complex array of pathogenic mechanisms, some of which may be common across different diseases albeit affecting different cell types and systems.




Update on Dementia


Book Description

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.




Herpesviridae


Book Description

Herpesviruses are unique among viruses as they encode for a complex self-regulatory system, aggressively invade and persist in the host, evade immune defense, alter all regulatory mechanisms of the macroorganism and modify the replication of heterologous viruses. Environmental factors influence these unconventional relationships. Consequently, a single herpesvirus species can be attributed to a wide range of diseases as etiological agents or cofactors. This book is intended to give an overview on selected clinical hot topics: herpes simplex virus encephalitis, persistent infection in the gingiva, thymidine kinase gene expression causing male infertility, and pharmaceutical reactivation of Epstein-Barr virus for oncolysis. Immune evasion mechanisms and new ways to formulate vaccines are exhaustively reviewed. Finally, a surprise: bovine herpesviruses could serve as models to study the pathomechanism of herpesviruses.




Mechanisms of Innate Neuroprotection


Book Description

As clinical trials of pharmacological neuroprotective strategies in stroke have been disappointing, attention has turned to the brain's own endogenous strategies for neuroprotection. Two endogenous mechanisms have been recently characterized, ischemic preconditioning and ischemic postconditioning. In the present topic newly characterized mechanisms involved in preconditioning- and postconditioning- neuroprotection will be discussed. The understanding of the mechanisms involved in the neuroprotective pathways induced by preconditioning and postconditioning will be clinically relevant for identifying new druggable target for neurodegenerative disorder therapy. Furthermore, the importance of these neuroprotective strategies resides in that it might be easily translatable into clinical practice. Therefore, the data presented here will highlight the capacity of ischemic preconditioning and postconditioning to be of benefit to humans.




The Biology of Alzheimer Disease


Book Description

Alzheimer disease causes the gradual deterioration of cognitive function, including severe memory loss and impairments in abstraction and reasoning. Understanding the complex changes that occur in the brain as the disease progressesincluding the accumulation of amyloid plaques and neurofibrillary tanglesis critical for the development of successful therapeutic approaches. Written and edited by leading experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine includes contributions covering all aspects of Alzheimer disease, from our current molecular understanding to therapeutic agents that could be used to treat and, ultimately, prevent it. Contributors discuss the biochemistry and cell biology of amyloid -protein precursor (APP), tau, presenilin, -secretase, and apolipoprotein E and their involvement in Alzheimer disease. They also review the clinical, neuropathological, imaging, and biomarker phenotypes of the disease; genetic alterations associated with the disorder; and epidemiological insights into its causation and pathogenesis. This comprehensive volume, which includes discussions of therapeutic strategies that are currently used or under development, is a vital reference for neurobiologists, cell biologists, pathologists, and other scientists pursuing the biological basis of Alzheimer disease, as well as investigators, clinicians, and students interested in its pathogenesis, treatment, and prevention.
