The designed conduits were investigated by physical, mechanical and microscopic analyses. The conduits were implanted into a 30-mm gap in the sciatic nerves of the rats. Four months after surgery, the regenerated nerves were evaluated by macroscopic assessments and histology. This polymeric conduit had sufficiently high mechanical properties to serve as a nerve guide. The results demonstrated that in the nanofibrous graft with cells, the sciatic nerve trunk had been reconstructed with restoration of nerve continuity and formatted nerve fibers with myelination. For the grafts especially the nanofibrous conduits with cells, muscle cells of gastrocnemius on the operated side were uniform in their size and structures. This study proves the feasibility of artificial conduit with Schwann cells for nerve regeneration by bridging a longer defect in a rat model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sciatic%20regeneration" title="sciatic regeneration">sciatic regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=Schwann%20cell" title=" Schwann cell"> Schwann cell</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20conduit" title=" artificial conduit"> artificial conduit</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibrous%20PHBV" title=" nanofibrous PHBV"> nanofibrous PHBV</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20assessments" title=" histological assessments"> histological assessments</a> </p> <a href="https://publications.waset.org/abstracts/21190/a-nanofi-brous-phbv-tube-with-schwann-cell-as-artificial-nerve-graft-contributing-to-rat-sciatic-nerve-regeneration-across-a-30-mm-defect-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">323</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">747</span> Development of 3D Printed, Conductive, Biodegradable Nerve Conduits for Neural Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei-Chia%20Huang">Wei-Chia Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jane%20Wang"> Jane Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Damage to nerves is considered one of the most irreversible injuries. The regeneration of nerves has always been an important topic in regenerative medicine. In general, damage to human tissue will naturally repair overtime. However, when the nerves are damaged, healed flesh wound cannot guarantee full restoration to its original function, as truncated nerves are often irreversible. Therefore, the development of treatment methods to successfully guide and accelerate the regeneration of nerves has been highly sought after. In order to induce nerve tissue growth, nerve conduits are commonly used to help reconnect broken nerve bundles to provide protection to the location of the fracture while guiding the growth of the nerve bundles. To prevent the protected tissue from becoming necrotic and to ensure the growth rate, the conduits used are often modified with microstructures or blended with neuron growth factors that may facilitate nerve regeneration. Electrical stimulation is another attempted treatment for medical rehabilitation. With appropriate range of voltages and stimulation frequencies, it has been demonstrated to promote cell proliferation and migration. Biodegradability are critical for medical devices like nerve conduits, while conductive polymers pose great potential toward the differentiation and growth of nerve cells. In this work, biodegradability and conductivity were combined into a novel biodegradable, photocurable, conductive polymer composite materials by embedding conductive nanoparticles in poly(glycerol sebacate) acrylate (PGSA) and 3D-printed into nerve conduits. Rat pheochromocytoma cells and rat neuronal Schwann cells were chosen for the in vitro tests of the conduits and had demonstrate selective growth upon culture in the conductive conduits with built-in microchannels and electrical stimulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20polymer" title="biodegradable polymer">biodegradable polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=3d%20printing" title=" 3d printing"> 3d printing</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20regeneration" title=" neural regeneration"> neural regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a> </p> <a href="https://publications.waset.org/abstracts/170754/development-of-3d-printed-conductive-biodegradable-nerve-conduits-for-neural-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170754.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">746</span> Bi-Layer Electro-Conductive Nanofibrous Conduits for Peripheral Nerve Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Nazeri">Niloofar Nazeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Derakhshan"> Mohammad Ali Derakhshan</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Faridi%20Majidi"> Reza Faridi Majidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Ghanbari"> Hossein Ghanbari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Injury of peripheral nervous system (PNS) can lead to loss of sensation or movement. To date, one of the challenges for surgeons is repairing large gaps in PNS. To solve this problem, nerve conduits have been developed. Conduits produced by means of electrospinning can mimic extracellular matrix and provide enough surface for further functionalization. In this research, a conductive bilayer nerve conduit with poly caprolactone (PCL), poly (lactic acid co glycolic acid) (PLGA) and MWCNT for promoting peripheral nerve regeneration was fabricated. The conduit was made of longitudinally aligned PLGA nanofibrous sheets in the lumen to promote nerve regeneration and randomly oriented PCL nanofibers on the outer surface for mechanical support. The intra-luminal guidance channel was made out of conductive aligned nanofibrous rolled sheets which are coated with laminin via dopamine. Different properties of electrospun scaffolds were investigated by using contact angle, mechanical strength, degradation time, scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The SEM analysis was shown that size range of nanofibrous mat were about 600-750 nm and MWCNTs deposited between nanofibers. The XPS result was shown that laminin attached to the nanofibers surface successfully. The contact-angle and tensile tests analysis revealed that scaffolds have good hydrophilicity and enough mechanical strength. In vitro studies demonstrated that this conductive surface was able to enhance the attachment and proliferation of PC12 and Schwann cells. We concluded that this bilayer composite conduit has good potential for nerve regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conductive" title="conductive">conductive</a>, <a href="https://publications.waset.org/abstracts/search?q=conduit" title=" conduit"> conduit</a>, <a href="https://publications.waset.org/abstracts/search?q=laminin" title=" laminin"> laminin</a>, <a href="https://publications.waset.org/abstracts/search?q=MWCNT" title=" MWCNT"> MWCNT</a> </p> <a href="https://publications.waset.org/abstracts/76928/bi-layer-electro-conductive-nanofibrous-conduits-for-peripheral-nerve-regeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">745</span> Bio-Functionalized Silk Nanofibers for Peripheral Nerve Regeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kayla%20Belanger">Kayla Belanger</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Vigneron"> Pascale Vigneron</a>, <a href="https://publications.waset.org/abstracts/search?q=Guy%20Schlatter"> Guy Schlatter</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernard%20Devauchelle"> Bernard Devauchelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Egles"> Christophe Egles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A severe injury to a peripheral nerve leads to its degeneration and the loss of sensory and motor function. To this day, there still lacks a more effective alternative to the autograft which has long been considered the gold standard for nerve repair. In order to overcome the numerous drawbacks of the autograft, tissue engineered biomaterials may be effective alternatives. Silk fibroin is a favorable biomaterial due to its many advantageous properties such as its biocompatibility, its biodegradability, and its robust mechanical properties. In this study, bio-mimicking multi-channeled nerve guidance conduits made of aligned nanofibers achieved by electrospinning were functionalized with signaling biomolecules and were tested in vitro and in vivo for nerve regeneration support. Silk fibroin (SF) extracted directly from silkworm cocoons was put in solution at a concentration of 10wt%. Poly(ethylene oxide) (PEO) was added to the resulting SF solution to increase solution viscosity and the following three electrospinning solutions were made: (1) SF/PEO solution, (2) SF/PEO solution with nerve growth factor and ciliary neurotrophic factor, and (3) SF/PEO solution with nerve growth factor and neurotrophin-3. Each of these solutions was electrospun into a multi-layer architecture to obtain mechanically optimized aligned nanofibrous mats. For in vitro studies, aligned fibers were treated to induce β-sheet formation and thoroughly rinsed to eliminate presence of PEO. Each material was tested using rat embryo neuron cultures to evaluate neurite extension and the interaction with bio-functionalized or non-functionalized aligned fibers. For in vivo studies, the mats were rolled into 5mm long multi-, micro-channeled conduits then treated and thoroughly rinsed. The conduits were each subsequently implanted between a severed rat sciatic nerve. The effectiveness of nerve repair over a period of 8 months was extensively evaluated by cross-referencing electrophysiological, histological, and movement analysis results to comprehensively evaluate the progression of nerve repair. In vitro results show a more favorable interaction between growing neurons and bio-functionalized silk fibers compared to pure silk fibers. Neurites can also be seen having extended unidirectionally along the alignment of the nanofibers which confirms a guidance factor for the electrospun material. The in vivo study has produced positive results for the regeneration of the sciatic nerve over the length of the study, showing contrasts between the bio-functionalized material and the non-functionalized material along with comparisons to the experimental control. Nerve regeneration has been evaluated not only by histological analysis, but also by electrophysiological assessment and motion analysis of two separate natural movements. By studying these three components in parallel, the most comprehensive evaluation of nerve repair for the conduit designs can be made which can, therefore, more accurately depict their overall effectiveness.

In this study, we developed a new hybrid bioreactor by adopting 50 Hz uniform alternative current (AC) magnetic stimulation and 4% strain mechanical stimulation. The guide tube for nerve regeneration is mesh structured tube made of biodegradable polymer, such as polylatic acid (PLA). However, when neural damage is large, there is a possibility that peripheral nerve undergoes necrosis. So it is quite important to accelerate the nerve tissue regeneration by achieving enhancement of nerve axonal extension rate. Therefore, we try to design and fabricate the system that can simultaneously load the uniform AC magnetic field stimulation and the stretch stimulation to cells for enhancement of nerve axonal extension. Next, we evaluated systems performance and the effectiveness of each stimulation for rat adrenal pheochromocytoma cells (PC12). First, we designed and fabricated the uniform AC magnetic field system and the stretch stimulation system. For the AC magnetic stimulation system, we focused on the use of pole piece structure to carry out in-situ microscopic observation. We designed an optimum pole piece structure using the magnetic field finite element analyses and the response surface methodology. We fabricated the uniform AC magnetic field stimulation system as a bio-reactor by adopting analytically determined design specifications. We measured magnetic flux density that is generated by the uniform AC magnetic field stimulation system. We confirmed that measurement values show good agreement with analytical results, where the uniform magnetic field was observed. Second, we fabricated the cyclic stretch stimulation device under the conditions of particular strains, where the chamber was made of polyoxymethylene (POM). We measured strains in the PC12 cell culture region to confirm the uniform strain. We found slightly different values from the target strain. Finally, we concluded that these differences were allowable in this mechanical stimulation system. We evaluated the effectiveness of each stimulation to enhance the nerve axonal extension using PC12. We confirmed that the average axonal extension length of PC12 under the uniform AC magnetic stimulation was increased by 16 % at 96 h in our bio-reactor. We could not confirm that the axonal extension enhancement under the stretch stimulation condition, where we found the exfoliating of cells. Further, the hybrid stimulation enhanced the axonal extension. Because the magnetic stimulation inhibits the exfoliating of cells. Finally, we concluded that the enhancement of PC12 axonal extension is due to the magnetic stimulation rather than the mechanical stimulation. Finally, we confirmed that the effectiveness of the uniform AC magnetic field stimulation for the nerve axonal extension using PC12 cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nerve%20cell%20PC12" title="nerve cell PC12">nerve cell PC12</a>, <a href="https://publications.waset.org/abstracts/search?q=axonal%20extension" title=" axonal extension"> axonal extension</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20regeneration" title=" nerve regeneration"> nerve regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic-mechanical%20stimulation" title=" electromagnetic-mechanical stimulation"> electromagnetic-mechanical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=bioreactor" title=" bioreactor"> bioreactor</a> </p> <a href="https://publications.waset.org/abstracts/73506/electromagnetic-mechanical-stimulation-on-pc12-for-enhancement-of-nerve-axonal-extension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">743</span> Close Loop Controlled Current Nerve Locator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20A.%20Alzomor">H.

Locating peripheral nerves is preferred to be done using nerve stimulation. In order to generate a nerve impulse by electrical means, a minimum threshold stimulus of current “rheobase” must be applied to the nerve. The technique depends on stimulating muscular twitching at a close distance to the nerve without actually touching it. Success rate of this operation depends on the accuracy of current intensity pulses used for stimulation. In this paper, we will discuss a circuit and algorithm for closed loop control for the current, theoretical analysis and test results and compare them with previous techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Close%20Loop%20Control%20%28CLC%29" title="Close Loop Control (CLC)">Close Loop Control (CLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=constant%20current" title=" constant current"> constant current</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20locator" title=" nerve locator"> nerve locator</a>, <a href="https://publications.waset.org/abstracts/search?q=rheobase" title=" rheobase"> rheobase</a> </p> <a href="https://publications.waset.org/abstracts/2622/close-loop-controlled-current-nerve-locator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2622.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">742</span> Development of Three-Dimensional Bio-Reactor Using Magnetic Field Stimulation to Enhance PC12 Cell Axonal Extension </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eiji%20Nakamachi">Eiji Nakamachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryota%20Sakiyama"> Ryota Sakiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Koji%20Yamamoto"> Koji Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuke%20Morita"> Yusuke Morita</a>, <a href="https://publications.waset.org/abstracts/search?q=Hidetoshi%20Sakamoto"> Hidetoshi Sakamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The regeneration of injured central nerve network caused by the cerebrovascular accidents is difficult, because of poor regeneration capability of central nerve system composed of the brain and the spinal cord. Recently, new regeneration methods such as transplant of nerve cells and supply of nerve nutritional factor were proposed and examined. However, there still remain many problems with the canceration of engrafted cells and so on and it is strongly required to establish an efficacious treating method of a central nerve system. Blackman proposed the electromagnetic stimulation method to enhance the axonal nerve extension. In this study, we try to design and fabricate a new three-dimensional (3D) bio-reactor, which can load a uniform AC magnetic field stimulation on PC12 cells in the extracellular environment for enhancement of an axonal nerve extension and 3D nerve network generation. Simultaneously, we measure the morphology of PC12 cell bodies, axons, and dendrites by the multiphoton excitation fluorescence microscope (MPM) and evaluate the effectiveness of the uniform AC magnetic stimulation to enhance the axonal nerve extension. Firstly, we designed and fabricated the uniform AC magnetic field stimulation bio-reactor. For the AC magnetic stimulation system, we used the laminated silicon steel sheets for a yoke structure of 3D chamber, which had a high magnetic permeability. Next, we adopted the pole piece structure and installed similar specification coils on both sides of the yoke. We searched an optimum pole piece structure using the magnetic field finite element (FE) analyses and the response surface methodology. We confirmed that the optimum 3D chamber structure showed a uniform magnetic flux density in the PC12 cell culture area by using FE analysis. Then, we fabricated the uniform AC magnetic field stimulation bio-reactor by adopting analytically determined specifications, such as the size of chamber and electromagnetic conditions. We confirmed that measurement results of magnetic field in the chamber showed a good agreement with FE results. Secondly, we fabricated a dish, which set inside the uniform AC magnetic field stimulation of bio-reactor. PC12 cells were disseminated with collagen gel and could be 3D cultured in the dish. The collagen gel were poured in the dish. The collagen gel, which had a disk shape of 6 mm diameter and 3mm height, was set on the membrane filter, which was located at 4 mm height from the bottom of dish. The disk was full filled with the culture medium inside the dish. Finally, we evaluated the effectiveness of the uniform AC magnetic field stimulation to enhance the nurve axonal extension. We confirmed that a 6.8 increase in the average axonal extension length of PC12 under the uniform AC magnetic field stimulation at 7 days culture in our bio-reactor, and a 24.7 increase in the maximum axonal extension length. Further, we confirmed that a 60 increase in the number of dendrites of PC12 under the uniform AC magnetic field stimulation. Finally, we confirm the availability of our uniform AC magnetic stimulation bio-reactor for the nerve axonal extension and the nerve network generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nerve%20regeneration" title="nerve regeneration">nerve regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=axonal%20extension" title=" axonal extension "> axonal extension </a>, <a href="https://publications.waset.org/abstracts/search?q=PC12%20cell" title=" PC12 cell"> PC12 cell</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20bio-reactor" title=" three-dimensional bio-reactor"> three-dimensional bio-reactor</a> </p> <a href="https://publications.waset.org/abstracts/80976/development-of-three-dimensional-bio-reactor-using-magnetic-field-stimulation-to-enhance-pc12-cell-axonal-extension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80976.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">741</span> Stimulation of Nerve Tissue Differentiation and Development Using Scaffold-Based Cell Culture in Bioreactors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Simon%20Grossemy">Simon Grossemy</a>, <a href="https://publications.waset.org/abstracts/search?q=Peggy%20P.%20Y.%20Chan"> Peggy P.

Scaffolds are used as a support to enhance nerve regeneration. In order to successfully design novel scaffolds and in vitro cell culture systems, a deep understanding of the factors affecting nerve regeneration processes is needed. Physical and biological parameters associated with the culture environment have been identified as potentially influential in nerve cell differentiation, including electrical stimulation, exposure to extracellular-matrix (ECM) proteins, dynamic medium conditions and co-culture with glial cells. The mechanisms involved in driving the cell to differentiation in the presence of these factors are poorly understood; the complexity of each of them raises the possibility that they may strongly influence each other. Some questions that arise in investigating nerve regeneration include: What are the best protein coatings to promote neural cell attachment? Is the scaffold design suitable for providing all the required factors combined? What is the influence of dynamic stimulation on cell viability and differentiation? In order to study these effects, scaffolds adaptable to bioreactor culture conditions were designed to allow electrical stimulation of cells exposed to ECM proteins, all within a dynamic medium environment. Gold coatings were used to make the surface of viscose rayon microfiber scaffolds (VRMS) conductive, and poly-L-lysine (PLL) and laminin (LN) surface coatings were used to mimic the ECM environment and allow the attachment of rat PC12 neural cells. The robustness of the coatings was analyzed by surface resistivity measurements, scanning electron microscope (SEM) observation and immunocytochemistry. Cell attachment to protein coatings of PLL, LN and PLL+LN was studied using DNA quantification with Hoechst. The double coating of PLL+LN was selected based on high levels of PC12 cell attachment and the reported advantages of laminin for neural differentiation. The underlying gold coatings were shown to be biocompatible using cell proliferation and live/dead staining assays. Coatings exhibiting stable properties over time under dynamic fluid conditions were developed; indeed, cell attachment and the conductive power of the scaffolds were maintained over 2 weeks of bioreactor operation. These scaffolds are promising research tools for understanding complex neural cell behavior. They have been used to investigate major factors in the physical culture environment that affect nerve cell viability and differentiation, including electrical stimulation, bioreactor hydrodynamic conditions, and combinations of these parameters. The cell and tissue differentiation response was evaluated using DNA quantification, immunocytochemistry, RT-qPCR and functional analyses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioreactor" title="bioreactor">bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20differentiation" title=" nerve differentiation"> nerve differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=PC12%20cells" title=" PC12 cells"> PC12 cells</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title=" scaffold"> scaffold</a> </p> <a href="https://publications.waset.org/abstracts/43994/stimulation-of-nerve-tissue-differentiation-and-development-using-scaffold-based-cell-culture-in-bioreactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43994.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">740</span> Optic Nerve Sheath Measurement in Children with Head Trauma </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabiha%20Sahin">Sabiha Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kursad%20Bora%20Carman"> Kursad Bora Carman</a>, <a href="https://publications.waset.org/abstracts/search?q=Coskun%20Yarar"> Coskun Yarar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Measuring the diameter of the optic nerve sheath is a noninvasive and easy to use imaging technique to predict intracranial pressure in children and adults. The aim was to measure the diameter of the optic nerve sheath in pediatric head trauma. Methods: The study group consisted of 40 children with healthy and 40 patients with head trauma. Transorbital sonographic measurement of the optic nerve sheath diameter was performed. Conclusion: The mean diameters of the optic nerve sheath of right and left eyes were 0.408 ± 0.064 mm and 0.417 ± 0.065 mm, respectively, in the trauma group. These results were higher in patients than in control group. There was a negative correlation between optic nerve sheath diameters and Glasgow Coma Scales in patients with head trauma (p < 0.05). There was a positive correlation between optic nerve sheath diameters and positive CT findings, systolic blood pressure in patients with head trauma. The clinical status of the patients at admission, blood pH and lactate level were related to the optic nerve sheath diameter. Conclusion: Measuring the diameter of the optic nerve sheath is not an invasive technique and can be easily used to predict increased intracranial pressure and to prevent secondary brain injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=head%20trauma" title="head trauma">head trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=intracranial%20pressure" title=" intracranial pressure"> intracranial pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=optic%20nerve" title=" optic nerve"> optic nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=sonography" title=" sonography"> sonography</a> </p> <a href="https://publications.waset.org/abstracts/104676/optic-nerve-sheath-measurement-in-children-with-head-trauma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">739</span> A Polyimide Based Split-Ring Neural Interface Electrode for Neural Signal Recording</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ning%20Xue">Ning Xue</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivas%20Merugu"> Srinivas Merugu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignacio%20Delgado%20Martinez"> Ignacio Delgado Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Sun"> Tao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Tsang"> John Tsang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shih-Cheng%20Yen"> Shih-Cheng Yen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have developed a polyimide based neural interface electrode to record nerve signals from the sciatic nerve of a rat. The neural interface electrode has a split-ring shape, with four protruding gold electrodes for recording, and two reference gold electrodes around the split-ring. The split-ring electrode can be opened up to encircle the sciatic nerve. The four electrodes can be bent to sit on top of the nerve and hold the device in position, while the split-ring frame remains flat. In comparison, while traditional cuff electrodes can only fit certain sizes of the nerve, the developed device can fit a variety of rat sciatic nerve dimensions from 0.6 mm to 1.0 mm, and adapt to the chronic changes in the nerve as the electrode tips are bendable. The electrochemical impedance spectroscopy measurement was conducted. The gold electrode impedance is on the order of 10 kΩ, showing excellent charge injection capacity to record neural signals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impedance" title="impedance">impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20interface" title=" neural interface"> neural interface</a>, <a href="https://publications.waset.org/abstracts/search?q=split-ring%20electrode" title=" split-ring electrode"> split-ring electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20signal%20recording" title=" neural signal recording"> neural signal recording</a> </p> <a href="https://publications.waset.org/abstracts/6287/a-polyimide-based-split-ring-neural-interface-electrode-for-neural-signal-recording" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6287.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">738</span> Analysis of Motor Nerve Conduction Velocity (MNCV) of Selected Nerves in Athletics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jogbinder%20Singh%20Soodan">Jogbinder Singh Soodan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashok%20Kumar"> Ashok Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Gobind%20Singh"> Gobind Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: This study aims to describe the motor nerve conduction velocity of selected nerves of both the upper and lower extremities in athletes. Thirty high-level sprinters (100 mts and 200 mts) and thirty high level distance runners (3000 mts) were volunteered to participate in the study. Method: Motor nerve conduction velocities (MNCV) of radial and sural nerves were recorded with the help of computerized equipment, NEUROPERFECT (MEDICAID SYSTEMS, India), with standard techniques of supramaximal percutaneus stimulation. The anthropometric measurements taken were body height (cms), age (yrs) and body weight (kgs). The neurophysiological parameters taken were MNCV of radial nerve (upper extremity) and sural nerve (lower extremity) of both sides (i.e. dominant and non-dominant) of the body. The room temperature was maintained at 37 degree Celsius. Results: Significant differences in motor nerve conduction velocities were found between dominant and non-dominant limbs in each group. The MNCV of radial nerve was obtained was significantly higher in the sprinters than long distance runners. The MNCV of sural nerve recorded was significantly higher in sprinters as compared to distance runners. Conclusion: The motor nerve conduction velocity of radial nerve was found to be higher in sprinters as compared to the distance runners and also, the MNCV for sural nerve was found to be higher in sprinters as compared to distance runners. In case of sprinters, the MNCV of radial and sural nerves were higher in dominant limbs (i.e. arms and legs) of both sides of the body. But, in case of distance runners, the MNCV of radial and sural nerves is higher in non dominant limbs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motor%20nerve%20conduction%20velocity" title="motor nerve conduction velocity">motor nerve conduction velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20nerve" title=" radial nerve"> radial nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=sural%20nerve" title=" sural nerve"> sural nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=sprinters" title=" sprinters"> sprinters</a> </p> <a href="https://publications.waset.org/abstracts/10891/analysis-of-motor-nerve-conduction-velocity-mncv-of-selected-nerves-in-athletics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10891.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">564</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">737</span> Examining the Change of Power Transmission Line in Urban Regeneration with Geographical Information System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Yagci">C.

The amount of the parcels, which are affected by the negativity of PTL is clearly seen with the aid of generated maps. Some kind of changes are exhibited in the system, which are created by GIS, for instance before urban regeneration PTL was very close to people’s private properties and huge parts of PTL were among the buildings, however; after urban regeneration electricity lines were changed their locations to the underground. According to the results, GIS can be used as a device in planning and managing of PTL in urban regeneration projects and can be used for analyses.

Area-based approach of neighborhood regeneration with the focus on people, place and system which covers the main sustainable aspects shall be studied as part of the solution. Project implementation in small scale without fully depending on the financial support from the government and main stakeholders is the advantage of neighborhood regeneration. This enables the improving and upgrading of living conditions to be ongoing even during the economy downturn. In addition to that, there will be no specific selection on the development areas as the entire nation share the similar opportunity to upgrade and to improve their neighborhood. This is important to narrow the income disparities in urban. The objective of this paper is to review and to summarize the urban regeneration in developed countries with the focus on Korea, Singapore and Hong Kong. The aim is to determine the direction of sustainable urban regeneration in Malaysia for post-Vision 2020 through the introduction of neighborhood regeneration. This paper is conducted via literature review and observations in those selected countries. In conclusion, neighborhood regeneration shall be one of the approach of sustainable urban regeneration in Malaysia. A few criteria have been identified and to be recommended for the adaptation in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=area-based%20regeneration" title="area-based regeneration">area-based regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20participation" title=" public participation"> public participation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20regeneration" title=" sustainable urban regeneration"> sustainable urban regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20redevelopment" title=" urban redevelopment"> urban redevelopment</a> </p> <a href="https://publications.waset.org/abstracts/54083/comparison-of-urban-regeneration-strategies-in-asia-and-the-development-of-neighbourhood-regeneration-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">735</span> Thermal Regeneration of CO2 Spent Palm Shell-Polyetheretherketone Activated Carbon Sorbents </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usman%20D.%20Hamza">Usman D.

The adsorption/desorption process was carried out using static volumetric adsorption. Regeneration is important in the overall economy of the process and waste minimization. This work focuses on the thermal regeneration of the CO2 exhausted microwave activated carbons. The regeneration strategy adopted was thermal with nitrogen purge desorption with N2 feed flow rate of 20 ml/min for 1 h at atmospheric pressure followed by drying at 1500C. Seven successive adsorption/regeneration processes were carried out on the material. It was found that after seven adsorption regeneration cycles; the regeneration efficiency (RE) for CO2 activated carbon from palm shell only (M4P0) was more than 90% while that of hybrid palm shell-PEEK (M4P2, M5P2) was above 95%. The cyclic adsorption and regeneration shows the stability of the adsorbent materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20shell-PEEK" title=" palm shell-PEEK"> palm shell-PEEK</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal" title=" thermal"> thermal</a> </p> <a href="https://publications.waset.org/abstracts/25253/thermal-regeneration-of-co2-spent-palm-shell-polyetheretherketone-activated-carbon-sorbents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25253.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">734</span> Evaluating the Logistic Performance Capability of Regeneration Processes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thorben%20Kuprat">Thorben Kuprat</a>, <a href="https://publications.waset.org/abstracts/search?q=Julian%20Becker"> Julian Becker</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Mayer"> Jonas Mayer</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Nyhuis"> Peter Nyhuis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For years now, it has been recognized that logistic performance capability contributes enormously to a production enterprise’s competitiveness and as such is a critical control lever.

Since production and regeneration processes have different characteristics, production planning and control measures cannot be directly transferred to regeneration processes.

The aim of this study was to assess the involvement of sensory and/or motor ulnar nerve fibers in patients with CTS and whether this affects the accuracy of the median versus ulnar sensory and motor comparative tests. Patients and methods: The present study included 145 CTS hands and 71 asymptomatic control hands. Clinical examination was done for all patients. The following tests were done for the patients and control: (1) Sensory conduction studies: median nerve, ulnar nerve, dorsal ulnar cutaneous nerve and median versus ulnar digit (D) four sensory comparative study; (2) Motor conduction studies: median nerve, ulnar nerve and median versus ulnar motor comparative study. Results: There were no statistically significant differences between patients and control group as regards parameters of ulnar motor study and dorsal ulnar cutaneous sensory conduction study. It was found that 17 CTS hands (11.7%) had ulnar sensory abnormalities in 17 different patients. The median versus ulnar sensory and motor comparative studies were abnormal among all these 17 CTS hands. There were statistically significant negative correlations between median motor latency and both ulnar sensory amplitudes recording D5 and D4. There were statistically significant positive correlations between median sensory conduction velocity and both ulnar sensory nerve action potential amplitude recording D5 and D4. Conclusions: There is ulnar sensory nerve abnormality among CTS patients. This abnormality affects the amplitude of ulnar sensory nerve action potential. The presence of abnormalities in ulnar nerve occurs in moderate and severe degrees of CTS. This does not affect the median versus ulnar sensory and motor comparative tests accuracy and validity for use in electrophysiological diagnosis of CTS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title="carpal tunnel syndrome">carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=ulnar%20nerve" title=" ulnar nerve"> ulnar nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20nerve" title=" median nerve"> median nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20versus%20ulnar%20comparative%20study" title=" median versus ulnar comparative study"> median versus ulnar comparative study</a>, <a href="https://publications.waset.org/abstracts/search?q=dorsal%20ulnar%20cutaneous%20nerve" title=" dorsal ulnar cutaneous nerve"> dorsal ulnar cutaneous nerve</a> </p> <a href="https://publications.waset.org/abstracts/19196/ulnar-nerve-changes-associated-with-carpal-tunnel-syndrome-and-effect-on-median-ersus-ulnar-comparative-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">567</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">732</span> Investigation of Soot Regeneration Behavior in the DPF Cleaning Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Won%20Jun%20Jo">Won Jun Jo</a>, <a href="https://publications.waset.org/abstracts/search?q=Man%20Young%20Kim"> Man Young Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To meet stringent diesel particulate matter regulations, DPF system is essential after treatment technology providing exceptional reliability and filtration performance. At low load driving conditions, the passive type of DPF system is ineffective for regeneration method due to the inadequate of engine exhaust heat in removing accumulated soot from the filter. Therefore, DPF cleaning device is necessary to remove the soot particles. In this work, the numerical analysis on the active regeneration of DPF in DPF cleaning device is performed to find the optimum operating conditions. In order to find the DPF regeneration characteristics during active regeneration, 5 different initial soot loading condition are investigated. As the initial soot mass increases, the maximum temperature of DPF and regeneration rate also increase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20regeneration" title="active regeneration">active regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=DPF%20cleaning%20device" title=" DPF cleaning device"> DPF cleaning device</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20drop" title=" pressure drop"> pressure drop</a>, <a href="https://publications.waset.org/abstracts/search?q=Diesel%20Particulate%20Filter" title=" Diesel Particulate Filter"> Diesel Particulate Filter</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20matters" title=" particulate matters"> particulate matters</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a> </p> <a href="https://publications.waset.org/abstracts/46196/investigation-of-soot-regeneration-behavior-in-the-dpf-cleaning-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">731</span> Ulnar Nerve Changes Associated with Carpal Tunnel Syndrome Not Affecting Median versus Ulnar Comparative Studies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Sayed%20El-Tawab"> Sarah Sayed El-Tawab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to assess the involvement of ulnar sensory and/or motor nerve fibers in patients with carpal tunnel syndrome (CTS) and whether this affects the accuracy of the median versus ulnar comparative tests. The present study included 145 CTS hands and 71 asymptomatic control hands. Clinical examination was done. The following tests were done: Sensory conduction studies: median, ulnar and dorsal ulnar cutaneous nerves; and median versus ulnar digit (D) four sensory comparative study; and motor conduction studies: median nerve, ulnar nerve and median versus ulnar motor comparative study. It was found that 17 CTS hands (11.7%) had ulnar sensory abnormalities in 17 different patients. The median versus ulnar sensory and motor comparative studies were abnormal among all these 17 CTS hands. There were significant negative correlations between median motor latency and both ulnar sensory amplitudes recording D5 and D4.

There are some factors that affect the temperature distribution and the nerve lesion size, one of these factors is the inhomogeneities in the tissue medium. Our objective is to calculate the temperature distribution and the nerve lesion size in a nonhomogenous medium surrounding the RF electrode. A two 3-D finite element models are used to compare the temperature distribution in the homogeneous and nonhomogeneous medium. Also the effect of temperature-dependent electric conductivity on maximum temperature and lesion size is observed. Results show that the presence of a nonhomogeneous medium around the RF electrode has a valuable effect on the temperature distribution and lesion size. The dependency of electric conductivity on tissue temperature increased lesion size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title="finite element model">finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20lesioning" title=" nerve lesioning"> nerve lesioning</a>, <a href="https://publications.waset.org/abstracts/search?q=pain%20relief" title=" pain relief"> pain relief</a>, <a href="https://publications.waset.org/abstracts/search?q=radiofrequency%20lesion" title=" radiofrequency lesion"> radiofrequency lesion</a> </p> <a href="https://publications.waset.org/abstracts/1842/modeling-of-radiofrequency-nerve-lesioning-in-inhomogeneous-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1842.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">417</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">729</span> Early Detection of Neuropathy in Leprosy-Comparing Clinical Tests with Nerve Conduction Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suchana%20Marahatta">Suchana Marahatta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabina%20Bhattarai"> Sabina Bhattarai</a>, <a href="https://publications.waset.org/abstracts/search?q=Bishnu%20Hari%20Paudel"> Bishnu Hari Paudel</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilip%20Thakur"> Dilip Thakur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Every year thousands of patients develop nerve damage and disabilities as a result of leprosy which can be prevented by early detection and treatment. So, early detection and treatment of nerve function impairment is of paramount importance in leprosy. Objectives: To assess the electrophysiological pattern of the peripheral nerves in leprosy patients and to compare it with clinical assessment tools. Materials and Methods: In this comparative cross-sectional study, 74 newly diagnosed leprosy patients without reaction were enrolled. They underwent thorough evaluation for peripheral nerve function impairment using clinical tests [i.e. nerve palpation (NP), monofilament (MF) testing, voluntary muscle testing (VMT)] and nerve conduction study (NCS). Clinical findings were compared with that of NCS using SPSS version 11.5. Results: NCS was impaired in 43.24% of leprosy patient at the baseline. Among them, sensory NCS was impaired in more patients (32.4%) in comparison to motor NCS (20.3%). NP, MF, and VMT were impaired in 58.1%, 25.7%, and 9.4% of the patients, respectively. Maximum concordance of monofilament testing and sensory NCS was found for sural nerve (14.7%). Likewise, the concordance of motor NP and motor NCS was the maximum for ulnar nerve (14.9%). When individual parameters of the NCS were considered, amplitude was found to be the most frequently affected parameter for both sensory and motor NCS. It was impaired in 100% of cases with abnormal NCS findings. Conclusion: Since there was no acceptable concordance between NCS findings and clinical findings, we should consider NCS whenever feasible for early detection of neuropathy in leprosy. The amplitude of both sensory nerve action potential (SNAP) and compound nerve action potential (CAMP) could be important determinants of the abnormal NCS if supported by further studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leprosy" title="leprosy">leprosy</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20function%20impairment" title=" nerve function impairment"> nerve function impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropathy" title=" neuropathy"> neuropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20conduction%20study" title=" nerve conduction study"> nerve conduction study</a> </p> <a href="https://publications.waset.org/abstracts/31963/early-detection-of-neuropathy-in-leprosy-comparing-clinical-tests-with-nerve-conduction-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31963.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">728</span> Management of Facial Nerve Palsy Following Physiotherapy </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassam%20Band">Bassam Band</a>, <a href="https://publications.waset.org/abstracts/search?q=Simon%20Freeman"> Simon Freeman</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohan%20Munir"> Rohan Munir</a>, <a href="https://publications.waset.org/abstracts/search?q=Hisham%20Band"> Hisham Band</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To determine efficacy of facial physiotherapy provided for patients with facial nerve palsy. Design: Retrospective study Subjects: 54 patients diagnosed with Facial nerve palsy were included in the study after they met the selection criteria including unilateral facial paralysis and start of therapy twelve months after the onset of facial nerve palsy. Interventions: Patients received the treatment offered at a facial physiotherapy clinic consisting of: Trophic electrical stimulation, surface electromyography with biofeedback, neuromuscular re-education and myofascial release. Main measures: The Sunnybrook facial grading scale was used to evaluate the severity of facial paralysis. Results: This study demonstrated the positive impact of physiotherapy for patient with facial nerve palsy with improvement of 24.2% on the Sunnybrook facial grading score from a mean baseline of 34.2% to 58.2%. The greatest improvement looking at different causes was seen in patient who had reconstructive surgery post Acoustic Neuroma at 31.3%. Conclusion: The therapy shows significant improvement for patients with facial nerve palsy even when started 12 months post onset of paralysis across different causes.

M. Prasad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge of variations of nerves of gluteal region is important for clinicians administering intramuscular injections, for orthopedic surgeons dealing with the hip surgeries, possibly for physiotherapists managing the painful conditions and paralysis of this region. Herein, we report multiple variations of the nerves of gluteal region. In the current case, the sciatic nerve was absent. The common peroneal and tibial nerves arose from sacral plexus and reached the gluteal region through greater sciatic foramen above and below piriformis respectively. The common peroneal nerve gave a muscular branch to the gluteus maximus. The inferior gluteal nerve and posterior cutaneous nerve of the thigh arose from a common trunk. The common trunk was formed by three roots. Upper and middle roots arose from sacral plexus and entered gluteal region through greater sciatic foramen respectively above and below piriformis. The lower root arose from the pudendal nerve and joined the common trunk. These variations were seen in the right gluteal region of an adult male cadaver aged approximately 70 years. Innervation of gluteus maximus by common peroneal nerve and presence of a common trunk of inferior gluteal nerve and posterior cutaneous nerve of the thigh make this case unique. The variant nerves may be subjected to iatrogenic injuries during surgical approach to the hip. They may also get compressed if there is a hypertrophy of the piriformis syndrome. Hence, the knowledge of these variations is of importance to clinicians, orthopedic surgeons and possibly for physiotherapists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gluteal%20region" title="gluteal region">gluteal region</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20variations" title=" multiple variations"> multiple variations</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20injury" title=" nerve injury"> nerve injury</a>, <a href="https://publications.waset.org/abstracts/search?q=sciatic%20nerve" title=" sciatic nerve"> sciatic nerve</a> </p> <a href="https://publications.waset.org/abstracts/30346/multiple-variations-of-the-nerves-of-gluteal-region-and-their-clinical-implications-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30346.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">726</span> Peripheral Nerves Cross-Sectional Area for the Diagnosis of Diabetic Polyneuropathy: A Meta-Analysis of Ultrasonographic Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Pourhassan">Saeed Pourhassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nastaran%20Maghbouli"> Nastaran Maghbouli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 1) Background It has been hypothesized that, in individuals with diabetes mellitus, the peripheral nerve is swollen due to sorbitol over-accumulation. Additionally growing evidence supported electro diagnostic study of diabetes induced neuropathy as a method having some challenges. 2) Objective To examine the performance of sonographic cross-sectional area (CSA) measurements in the diagnosis of diabetic polyneuropathy (DPN). 3) Data Sources Electronic databases, comprising PubMed and EMBASE and Google scholar, were searched for the appropriate studies before Jan 1, 2020. 4) Study Selection Eleven trials comparing different peripheral nerve CSA measurements between participants with and without DPN were included. 5) Data Extraction Study design, participants' demographic characteristics, diagnostic reference of DPN, and evaluated peripheral nerves and methods of CSA measurement. 6) Data Synthesis Among different peripheral nerves, Tibial nerve diagnostic odds ratios pooled from five studies (713 participants) were 4.46 (95% CI, 0.35–8.57) and the largest one with P<0.0001, I²:64%. Median nerve CSA at wrist and mid-arm took second and third place with ORs= 2.82 (1.50-4.15), 2.02(0.26-3.77) respectively. The sensitivities and specificities pooled from two studies for Sural nerve were 0.78 (95% CI, 0.68–0.89), and 0.68 (95% CI, 0.53–0.74). Included studies for other nerves were limited to one study. The largest sensitivity was for Sural nerve and the largest specificity was for Tibial nerve. 7) Conclusions The peripheral nerves CSA measured by ultrasound imaging is useful for the diagnosis of DPN and is most significantly different between patients and participants without DPN at the Tibial nerve. Because the Tibial nerve CSA in healthy participants, at various locations, rarely exceeds 24 mm2, this value can be considered as a cutoff point for diagnosing DPN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=polyneuropathy" title=" polyneuropathy"> polyneuropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/124321/peripheral-nerves-cross-sectional-area-for-the-diagnosis-of-diabetic-polyneuropathy-a-meta-analysis-of-ultrasonographic-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124321.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">725</span> Electrochemical Regeneration of GIC Adsorbent in a Continuous Electrochemical Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20N.%20Hussain">S.

The numerical study reveals the self-similar spectral broadening very effective for 2R all-optical regeneration; the proposed design presents high stability compared to a conventional regenerator using SPM broadening with reduction of the intensity fluctuations and improvement of the extinction ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=all-optical%20function" title="all-optical function">all-optical function</a>, <a href="https://publications.waset.org/abstracts/search?q=2R%20optical%20regeneration" title=" 2R optical regeneration"> 2R optical regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=self-similar%20broadening" title=" self-similar broadening"> self-similar broadening</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamyshev%20regenerator" title=" Mamyshev regenerator"> Mamyshev regenerator</a> </p> <a href="https://publications.waset.org/abstracts/101178/all-optical-function-based-on-self-similar-spectral-broadening-for-2r-regeneration-in-high-bit-rate-optical-transmission-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101178.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">186</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">722</span> Sensitivity and Specificity of Clinical Testing for Digital Nerve Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guy%20Rubin">Guy Rubin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ravit%20Shay"> Ravit Shay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nimrod%20Rozen"> Nimrod Rozen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The accuracy of a diagnostic test used to classify a patient as having disease or being disease-free is a valuable piece of information to be used by the physician when making treatment decisions. Finger laceration, suspected to have nerve injury is a challenging decision for the treating surgeon. The purpose of this study was to evaluate the sensitivity, specificity and predictive values of six clinical tests in the diagnosis of digital nerve injury. The six clinical tests included light touch, pin prick, static and dynamic 2-point discrimination, Semmes Weinstein monofilament and wrinkle test. Data comparing pre-surgery examination with post-surgery results of 42 patients with 52 digital nerve injury was evaluated. The subjective examinations, light touch, pin prick, static and dynamic 2-point discrimination and Semmes-Weinstein monofilament were not sensitive (57.6, 69.7, 42.4, 40 and 66.8% respectively) and specific (36.8, 36.8, 47.4, 42.1 and 31.6% respectively). Wrinkle test, the only objective examination, was the most sensitive (78.1%) and specific (55.6%). This result gives no pre-operative examination the ability to predict the result of explorative surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20nerve" title="digital nerve">digital nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=injury" title=" injury"> injury</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20examination" title=" nerve examination"> nerve examination</a>, <a href="https://publications.waset.org/abstracts/search?q=Semmes-Weinstein%20monofilamen" title=" Semmes-Weinstein monofilamen"> Semmes-Weinstein monofilamen</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=specificity" title=" specificity"> specificity</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20point%20discrimination" title=" two point discrimination"> two point discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=wrinkle%20test" title=" wrinkle test"> wrinkle test</a> </p> <a href="https://publications.waset.org/abstracts/74474/sensitivity-and-specificity-of-clinical-testing-for-digital-nerve-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74474.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">721</span> Median Versus Ulnar Medial Thenar Motor Recording in Diagnosis Of Carpal Tunnel Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim of the work: This study proposed to assess the role of the median versus ulnar medial thenar motor (MTM) recording in supporting the diagnosis of carpal tunnel syndrome (CTS). Patients and methods: The present study included 130 hands (70 CTS and 60 controls). Clinical examination was done for all patients. The following tests were done (using surface electrodes recording) for patients and control: (1) sensory nerve conduction studies: median nerve, ulnar nerve and median versus ulnar digit four sensory study; (2) motor nerve conduction studies: median nerve, ulnar nerve, median (second lumbrical) versus ulnar (interosseous) (2-LINT) motor study and median versus ulnar (MTM) study. Results: The tests with higher sensitivity in diagnosing CTS were median versus ulnar (2-LINT) motor latency difference (87.1%), median versus ulnar (MTM) motor latency difference (80%) and median versus ulnar digit four sensory latency differences (91.4%). There was no statistically significant difference between median versus ulnar (MTM) motor latency difference with both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency difference (P > 0.05) as regards the confirmation of CTS. Conclusions: Median versus ulnar (MTM) motor latency difference has high sensitivity and specificity for the diagnosis of CTS as for both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency differences. It can be considered a useful neurophysiological test to be used in combination with another median versus ulnar comparative tests for confirming the diagnosis of CTS beside other well-known electrophysiological tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title="carpal tunnel syndrome">carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=medial%20thenar%20motor" title=" medial thenar motor"> medial thenar motor</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20nerve" title=" median nerve"> median nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=ulnar%20nerve" title=" ulnar nerve"> ulnar nerve</a> </p> <a href="https://publications.waset.org/abstracts/29852/median-versus-ulnar-medial-thenar-motor-recording-in-diagnosis-of-carpal-tunnel-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29852.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">720</span> Vestibular Schwannoma: A Rare Cause of Trigeminal Nerve Paraesthesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jessie%20Justice">Jessie Justice</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This is a case report of a vestibular schwannoma presenting with numbness to the left lower lip and tongue and altered taste. The aim of this case is to raise awareness of differential diagnoses for trigeminal nerve paraesthesia and, hence, prompt thorough investigation. A 65-year-old male was referred to the Oral and Maxillofacial department regarding sudden-onset of numbness to his left lower lip and left tongue, with altered taste sensation subsequently developing. The patient was simultaneously being investigated for severe hearing loss in his left ear. On examination, there was altered sensation in the distribution of the left inferior alveolar nerve and left lingual nerve. There was no palpable cervical lymphadenopathy and no intra-oral lesions or dental cause for the symptoms. Due to his hearing loss in the left ear, the patient was sent for magnetic resonance imaging of the internal auditory meatus by the Ear, Nose and Throat (ENT) department, revealing a 2.5cm mass within the left cerebellopontine angle presumed to be a vestibular schwannoma. This led to the diagnosis of trigeminal nerve compression by a medium vestibular schwannoma. Consequently, the patient was followed up by an ENT, who referred him for stereotactic radiosurgery. A literature review regarding vestibular schwannomas presenting with orofacial paraesthesia was then carried out. A review of the literature has shown the incidence of vestibular schwannoma to be 3-5 cases per 100,000. It has been reported that approximately 5% of vestibular schwannoma cases display orofacial dysaesthesia, and about 1-3% of cases exhibit trigeminal neuralgia symptoms. This is a rare case of vestibular schwannoma causing trigeminal nerve paraesthesia. The aim of this study is to raise awareness of alternative causes of trigeminal nerve paraesthesia and the available literature surrounding this. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20neuroma" title="acoustic neuroma">acoustic neuroma</a>, <a href="https://publications.waset.org/abstracts/search?q=orofacial%20dysaesthesia" title=" orofacial dysaesthesia"> orofacial dysaesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=trigeminal%20nerve%20paraesthesia" title=" trigeminal nerve paraesthesia"> trigeminal nerve paraesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=vestibular%20schwannoma" title=" vestibular schwannoma"> vestibular schwannoma</a> </p> <a href="https://publications.waset.org/abstracts/193761/vestibular-schwannoma-a-rare-cause-of-trigeminal-nerve-paraesthesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">14</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">719</span> Cultural Event and Urban Regeneration: Lessons from Liverpool as the 2008 European Capital of Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi-De%20Liu">Yi-De Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For many European cities, a key motivation in developing event strategies is to use event as a catalyst for urban regeneration. One type of event that is particularly used as a means of urban development is the European Capital of Culture (ECOC) initiative. Based on a case study of the 2008 ECOC Liverpool, this paper aims at conceptualising the significance of major event for a city’s economic, cultural and social regenerations. In terms of economic regeneration, the role of the ECOC is central in creating Liverpool’s visitor economy and reshaping city image. Liverpool planned different themes for eight consecutive years as a way to ensure economic sustainability. As far as cultural regeneration is concerned, the ECOC contributed to the cultural regeneration of Liverpool by stimulating cultural participation and interest from the demand side, as well as improving cultural provision and collaboration within the cultural sector from the supply side. So as to social regeneration, Liverpool treated access development as a policy guideline and considered the ECOC as an opportunity to enhance the sense of place. The most significant lesson learned from Liverpool is its long-term planning and efforts made to integrate the ECOC into the overall urban development strategy. As a result, a more balanced and long-term effect on urban regeneration could be achieved. <p class="card-text"><strong>Keywords:</strong> <a
