The field of neural transplantation is at a crucial stage, with important clinical trials on transplantation in patients with Parkinson's disease nearing completion and novel, alternative approaches to fetal transplantation being developed. This timely book brings together leading neuroscientists, clinicians, and cell and developmental biologists to discuss the use of neural transplants in neurodegenerative disorders, such as Parkinson's disease, Huntington's chorea, amyotrophic lateral sclerosis, multiple sclerosis and spinal cord injury. There is also extensive coverage of the potential alternatives to freshly derived fetal tissue as the source of transplants, for example xenografts, encapsulated cells and immortalized stem cells. With authoritative contributions and lively discussion sections, this book presents much new and exciting work in this field and identifies promising new research directions.
This book summarizes early pioneering achievements in the field of human neural stem cell (hNSC) research and combines them with the latest advances in stem cell technology, including reprogramming and gene editing. The powerful potential of hNSC to generate and repair the developing and adult CNS has been confirmed by numerous experimental in vitro and in vivo studies. The book presents methods for hNSC derivation and discusses the mechanisms underlying NSC in vitro fate decisions and their in vivo therapeutic mode of action. The long-standing dogma that the human central nervous system (CNS) lacks the ability to regenerate was refuted at the end of the 20th century, when evidence of the presence of neurogenic zones in the adult human brain was found. These neurogenic zones are home to human neural stem cells (hNSCs), which are capable of self-renewing and differentiating into neurons, astrocytes and oligodendrocytes. NSCs isolated from human CNS have a number of clinical advantages, especially the innate potential to differentiate into functional neural cells. Nevertheless, their full clinical exploitation has been hindered by limited access to the tissue and low expansion potential. The search for an alternative to CNS sources of autologous, therapeutically competent hNSCs was the driving force for the many studies proving the in vitro plasticity of different somatic stem cells to generate NSCs and their functional progeny. Now the era of induced pluripotent stem cells has opened entirely new opportunities to achieve research and therapeutic goals with the aid of hNSCs.
The editor of this volume, having research interests in the field of ROS production and the damage to cellular systems, has identified a number of enzymes showing ·OH scavenging activities details of which are anticipated to be published in the near future as confirmatory experiments are awaited. It is hoped that the information presented in this book on NDs will stimulate both expert and novice researchers in the field with excellent overviews of the current status of research and pointers to future research goals. Clinicians, nurses as well as families and caregivers should also benefit from the material presented in handling and treating their specialised cases. Also the insights gained should be valuable for further understanding of the diseases at molecular levels and should lead to development of new biomarkers, novel diagnostic tools and more effective therapeutic drugs to treat the clinical problems raised by these devastating diseases.
This book begins with a synopsis of experimental work underlying degeneration and recovery in the nervous system, which is then discussed in the context of strategies to repair the central nervous system (CNS) and peripheral nervous system (PNS). The major part of the book is given over to the approach involving the use of transplanted tissues to replace and restore disrupted neural networks. This experimental work has formed the basis for the emerging clinical trials employing neural grafts for diseases such as Parkinson's and Huntington's, which are discussed in detail. The book then goes on to discuss newer cellular strategies involving the manipulation of neural cells both in culture and genetically, an approach that may ultimately be employed in the clinical situation. Neural Repair, Transplantation and Rehabilitation is unique in bridging the gap from experimental studies to clinical trials, whilst also providing the non-specialist with a background in rehabilitation strategies as well as basic neuroscience. It is recommended for all those involved in the management of patients with degenerative and traumatic injuries to the nervous system.
Active neuroscientists survey NSCs as potential tools for central nervous system and spinal cord repair by explaining their clinically significant fundamental properties, manipulations, and potential therapeutic paradigms. Their discussion of the fundamental biology of NSCs illustrates the signaling pathways that regulate stem cell division and differentiation, and defines the methods of NSC expansion and propagation, neuromorphogenesis, the factors determining cell fate both in vitro and in situ, and the induction of self-reparative processes within the brain. They also present strategies that may lead to fruitful clinical applications in the near future. These range from the replacement of degenerated, dysfunctional, or maldeveloped cells to the provision of factors that may protect, correct, recruit, promote self-repair, or mediate the connectivity of host cells.
This book delineates how systems biology, pharmacogenomic, and behavioral approaches, as applied to neurodevelopmental toxicology, provide a structure to arrange information in a biological model. The text reviews and discusses approaches that can be used as effective tools to dissect mechanisms underlying pharmacological and toxicological phenomena associated with the exposure to drugs or environmental toxicants during development. The book intends to elaborate functional outcomes of component-to-component relationships using rodent and nonhuman primate in vitro and in vivo models that allow for the directional and quantitative description of the complete organism in response to environmental perturbations. In addition, attention has also been directed to some of the more recent methodologies, including genomics, proteomics and metabolomics, applied in the evolutionary neurobiological field.
This new series, based on a bi-annual conference and its topics, represents a major contribution to the emerging science of cancer research and regenerative medicine. Each volume brings together some of the most pre-eminent scientists working on cancer biology, cancer treatment, cancer diagnosis, cancer prevention and regenerative medicine to share information on currently ongoing work which will help shape future therapies. These volumes are invaluable resources not only for already active researchers or clinicians but also for those entering these fields, plus those in industry. Tissue Engineering and Regenerative Medicine is a proceedings volume which reflects papers presented at the 3rd bi-annual Innovations in Regenerative Medicine and Cancer Research conference; taken with its companion volume Stem Cells: Biology and Engineering it provides a complete overview of the papers from that meeting of international experts.
Possible new breakthroughs in understanding the aging mind that can be used to benefit older people are now emerging from research. This volume identifies the key scientific advances and the opportunities they bring. For example, science has learned that among older adults who do not suffer from Alzheimer's disease or other dementias, cognitive decline may depend less on loss of brain cells than on changes in the health of neurons and neural networks. Research on the processes that maintain neural health shows promise of revealing new ways to promote cognitive functioning in older people. Research is also showing how cognitive functioning depends on the conjunction of biology and culture. The ways older people adapt to changes in their nervous systems, and perhaps the changes themselves, are shaped by past life experiences, present living situations, changing motives, cultural expectations, and emerging technology, as well as by their physical health status and sensory-motor capabilities. Improved understanding of how physical and contextual factors interact can help explain why some cognitive functions are impaired in aging while others are spared and why cognitive capability is impaired in some older adults and spared in others. On the basis of these exciting findings, the report makes specific recommends that the U.S. government support three major new initiatives as the next steps for research.
This book represents the third in a series of International Conferences related to Alzheimer's (AD) and Parkinson's (PD) diseases. The first one took place in Eilat, Israel, in 1985; and the second one in Kyoto, Japan, in 1989. This book contains the full text of oral and poster presentations from the Third International Conference on Alzheimer's and Parkinson's Diseases: Recent Developments, held in Chicago, Illinois, U.S.A. on November 1-6, 1993. The Chicago Conference was attended by 270 participants. The Scientific Program was divided into nine oral sessions, a keynote presentation, and a poster session. The conference culminated in a Round Table Discussion involving all of the participants in the conference. The four and one-half day meeting served as an excellent medium for surveying the current status of clinical and preclinical developments in AD and PD. There were 59 oral presentations and 93 posters. This book incorporates a majority of both.
The past two decades have seen unparalleled developments in our knowledge of the brain and mind. However, these advances have forced us to confront head-on some significant ethical issues regarding our application of this information in the real world- whether using brain images to establish guilt within a court of law, or developing drugs to enhance cognition. Historically, any consideration of the ethical, legal, and social implications of emerging technologies in science and medicine has lagged behind the discovery of the technology itself. These delays have caused problems in the acceptability and potential applications of biomedical advances and posed significant problems for the scientific community and the public alike - for example in the case of genetic screening and human cloning. The field of Neuroethics aims to proactively anticipate ethical, legal and social issues at the intersection of neuroscience and ethics, raising questions about what the brain tells us about ourselves, whether the information is what people want or ought to know, and how best to communicate it. A landmark in the academic literature, the Oxford Handbook of Neuroethics presents a pioneering review of a topic central to the sciences and humanities. It presents a range of chapters considering key issues, discussion, and debate at the intersection of brain and ethics. The handbook contains more than 50 chapters by leaders from around the world and a broad range of sectors of academia and clinical practice spanning the neurosciences, medical sciences and humanities and law. The book focuses on and provides a platform for dialogue of what neuroscience can do, what we might expect neuroscience will do, and what neuroscience ought to do. The major themes include: consciousness and intention; responsibility and determinism; mind and body; neurotechnology; ageing and dementia; law and public policy; and science, society and international perspectives. Tackling some of the most significant ethical issues that face us now and will continue to do so over the coming decades, The Oxford Handbook of Neuroethics will be an essential resource for the field of neuroethics for graduate students and postdoctoral fellows, basic scientists in the neurosciences and psychology, scholars in humanities and law, as well as physicians practising in the areas of primary care in neurological medicine.
