Download or read book Epidural Spinal Stimulation is Associated with Changes in Surviving Axons and Associated Glial Cells After Spinal Cord Injury in Rodents written by Kyleigh Alexis DePetro and published by . This book was released on 2017 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: We previously demonstrated that epidural spinal stimulation (ES) and transcutaneous stimulation combined with step training can restore voluntary motor control in humans with chronic, motor-complete spinal cord injuries in at least 24 hours. The purpose of this study was to determine the underlying pathways involved. We hypothesized that chronic ES can provide motor improvements that persist in the absence of stimulation and that both surviving axons and their associated glial cells play important roles in ES-facilitated recovery. Our kinematic data suggested that chronic ES is associated with persistent motor recovery when ES is off. Our histological analysis demonstrated that the node of Ranvier, oligodendrocytes, astrocytic process extension, and apoptosis play important roles in mediating axonal integrity associated with functional motor improvement with ES in rats.
Download or read book Transplantation of Olfactory Ensheathing Cells Combined with Epidural Stimulation and Climb Training as a Long term Treatment for Severe Spinal Cord Injury in Rodents written by Kaitlin Lee Ingraham Dixie and published by . This book was released on 2019 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following a severe spinal cord injury (SCI), transplanted olfactory ensheathing cells (OECs) reduce inhibitory factors and promote axonal outgrowth at the lesion site to help reestablish circuit connectivity needed for functional recovery. Another promising therapy, electrical epidural stimulation (EES), also helps to reestablish connectivity but targets the spinal cord caudal to the injury. This study asked if the combination of OEC transplantation and administration of EES during climb training would improve recovery. Two cohorts of inbred Fischer 344 rats received a severe SCI and a two-week delayed transplant of OECs, media, or fibroblasts (FBs). Rats then received EES while performing a climbing task 3 times/week and were perfused at 5.5-6.5 months post-injury. We found that scores on the BBB locomotor test improved for all groups over time, but no consistent changes in climbing ability were detected. When we examined the injury sites, we found surviving GFP-labeled OECs and FBs for the first time at 6 months post-transplant. We also found that OEC treatment increased the amount of serotonergic and neurofilament (NF)-positive axons in the lesion core compared to media- and FB-treated controls. This was particularly true in areas of the lesion core with OECs where we found greater levels of axon density than in areas without OECs. Further, the percent of NF-positive axons associated with myelin proteins was greater in OEC- compared to media-treated rats. The OECs in the lesion core also interacted with serotonergic axons, myelinating and non-myelinating Schwann cells (SCs), and oligodendrocytes and expressed protein markers typically associated with SC-like myelin. Overall our results provide evidence that OEC transplantation combined with EES may be a beneficial treatment for severe SCI.
Download or read book The Spinal Cord written by Charles Watson and published by Academic Press. This book was released on 2009-11-27 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many hundreds of thousands suffer spinal cord injuries leading to loss of sensation and motor function in the body below the point of injury. Spinal cord research has made some significant strides towards new treatment methods, and is a focus of many laboratories worldwide. In addition, research on the involvement of the spinal cord in pain and the abilities of nervous tissue in the spine to regenerate has increasingly been on the forefront of biomedical research in the past years. The Spinal Cord, a collaboration with the Christopher and Dana Reeve Foundation, is the first comprehensive book on the anatomy of the mammalian spinal cord. Tens of thousands of articles and dozens of books are published on this subject each year, and a great deal of experimental work has been carried out on the rat spinal cord. Despite this, there is no comprehensive and authoritative atlas of the mammalian spinal cord. Almost all of the fine details of spinal cord anatomy must be searched for in journal articles on particular subjects. This book addresses this need by providing both a comprehensive reference on the mammalian spinal cord and a comparative atlas of both rat and mouse spinal cords in one convenient source. The book provides a descriptive survey of the details of mammalian spinal cord anatomy, focusing on the rat with many illustrations from the leading experts in the field and atlases of the rat and the mouse spinal cord. The rat and mouse spinal cord atlas chapters include photographs of Nissl stained transverse sections from each of the spinal cord segments (obtained from a single unfixed spinal cord), detailed diagrams of each of the spinal cord segments pictured, delineating the laminae of Rexed and all other significant neuronal groupings at each level and photographs of additional sections displaying markers such as acetylcholinesterase (AChE), calbindin, calretinin, choline acetlytransferase, neurofilament protein (SMI 32), enkephalin, calcitonin gene-related peptide (CGRP), and neuronal nuclear protein (NeuN). The text provides a detailed account of the anatomy of the mammalian spinal cord and surrounding musculoskeletal elements The major topics addressed are: development of the spinal cord; the gross anatomy of the spinal cord and its meninges; spinal nerves, nerve roots, and dorsal root ganglia; the vertebral column, vertebral joints, and vertebral muscles; blood supply of the spinal cord; cytoarchitecture and chemoarchitecture of the spinal gray matter; musculotopic anatomy of motoneuron groups; tracts connecting the brain and spinal cord; spinospinal pathways; sympathetic and parasympathetic elements in the spinal cord; neuronal groups and pathways that control micturition; the anatomy of spinal cord injury in experimental animals The atlas of the rat and mouse spinal cord has the following features: Photographs of Nissl stained transverse sections from each of 34 spinal segments for the rat and mouse; Detailed diagrams of each of the 34 spinal segments for rat and mouse, delineating the laminae of Rexed and all other significant neuronal groupings at each level. ; Alongside each of the 34 Nissl stained segments, there are additional sections displaying markers such as acetylcholinesterase, calbindin, calretinin, choline acetlytransferase, neurofilament protein (SMI 32), and neuronal nuclear protein (NeuN) All the major motoneuron clusters are identified in relation to the individual muscles or muscle groups they supply

Download or read book Galanin written by Tomas Hökfelt and published by Springer Science & Business Media. This book was released on 2010-08-18 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galanin is a neuropeptide found both in the central and peripheral nervous system. The 29-amino acid peptide (named after its N-terminal glycine and C-terminal alanine) was identified in 1983 by its C-terminal amidation. This 'reverse' approach, that is to discover a substance through a distinct chemical feature, and only subsequently to characterize its biological activity, was novel and has been successful in the identification of several other peptides. After the structure of galanin was determined in 1983, functional studies were performed with material purified from natural sources until the synthetic form of the peptide became available. Galanin can act as transmitter, modulator and trophic factor, and is involved in a number of physiological processes such as hormone secretion, cardiovascular mechanisms, feeding and cognition. This peptide may also be of significance for a number of pathological processes/disorders including pain, depression, Alzheimer's disease, epilepsy, addiction and cancer. This wide diversity of actions is mediated by three galanin receptor subtypes. The studies reviewed in this volume give a fairly complete overview of the spectrum of the biological actions and functions of galanin and its receptors and on possible therapeutic applications in a number of pathological conditions.

Download or read book The Neural Crest written by Nicole Le Douarin and published by Cambridge University Press. This book was released on 1999-11-28 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1999 edition of The Neural Crest contains comprehensive information about the neural crest, a structure unique to the vertebrate embryo, which has only a transient existence in early embryonic life. The ontogeny of the neural crest embodies the most important issues in developmental biology, as the neural crest is considered to have played a crucial role in evolution of the vertebrate phylum. Data that analyse neural crest ontogeny in murine and zebrafish embryos have been included in this revision. This revised edition also takes advantage of recent advances in our understanding of markers of neural crest cell subpopulations, and a full chapter is now devoted to cell lineage analysis. The major research breakthrough since the first edition has been the introduction of molecular biology to neural crest research, enabling an elucidation of many molecular mechanisms of neural crest development. This book is essential reading for students and researchers in developmental biology, cell biology, and neuroscience.
Download or read book Restorative Neurology of Spinal Cord Injury written by Milan R. Dimitrijevic and published by OUP USA. This book was released on 2012-01-12 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following injury or disease, neural circuitry can be altered to varying degrees leading to highly individualized characteristics that may or may not resemble original function. In addition, lost or partially damaged circuits and the effects of biological recovery processes coupled with learned compensatory strategies create a new neuroanatomy with capabilities that are often not functional or may interfere with daily life. To date, the majority of approaches used to treat neurological dysfunction have focused on the replacement of lost or damaged function, usually through the suppression of surviving neural activity and the application of mechanical assistive devices. Restorative Neurology of Spinal Cord Injury offers a different and novel approach. Focusing on the spinal cord and its role in motor control, the book details the clinical and neurophysiological assessment process and methods developed throughout the past half century by basic and clinical scientists. Then, through the use of specialized clinical and neurophysiological testing methods, conduction and processing performed within the surviving neural circuitry is examined and characterized in detail. Based on the results of such assessment, treatment strategies, also described in this book, are applied to augment, rather than replace, the performance of surviving neural circuitry and improve the functional capacity of people who have experienced injury to their spinal cords.
