Caspase-3 is a key enzyme that regulating cell death. Our objective was to examine the influence of anti-apoptotic drug Z-VAD-FMK (pan-caspase inhibitor) on in vitro viability of dog follicles within the ovarian cortex. Ovaries were obtained from prepubertal (age, 2.5–6 months) and adult (age, 8 months to 2 years) bitches and ovarian cortical fragments were recovered. The cortices were then incubated on 1.5% (w/v) agarose gel blocks within a 24-wells culture plate (three cortical pieces/well) containing Minimum Essential Medium Eagle - Alpha Modification (Alpha MEM) supplemented with 4.2 µg/ml insulin, 3.8 µg/ml transferrin, 5 ng/ml selenium, 2 mM L-glutamine, 100 µg/mL of penicillin G sodium, 100 µg/mL of streptomycin sulfate, 0.05 mM ascorbic acid, 10 ng/mL of FSH and 0.1% (w/v) polyvinyl alcohol in humidified atmosphere of 5% CO2 and 5% O2. The cortices were divided in six treatment groups: 1) 10 ng/mL EGF (EGF V0); 2) 10 ng/mL of EGF plus 1 mM Z-VAD-FMK (EGF V1); 3) 10 ng/mL of EGF and 10 mM Z-VAD-FMK (EGF V10); 4) 1 mM Z-VAD-FMK; 5) 10 mM Z-VAD-FMK and (6) no EGF and Z-VAD-FMK supplementation. Ovarian follicles within the tissues were processed for histology and assessed for follicle density, viability (based on morphology) and diameter immediately after collection (Control) or after 3 or 7 days of in vitro incubation. Comparison among fresh and culture treatment group was performed using ANOVA test. There were no differences (P > 0.05) in follicle density and viability among different culture treatments. However, there were differences in this parameter between culture days. Specifically, culturing tissue for 7 days resulted in significant reduction in follicle viability and density, regardless of treatments. We found a difference in size between culture days when these follicles were cultured using 10 mM Z-VAD-FMK or 10 ng/mL EGF (EGF V0). In sum, the finding demonstrated that Z-VAD-FMK at the dosage used in the present study does not provide the protective effect to ovarian tissue during in vitro culture. Future studies should explore different Z-VAD-FMK dosages or other anti-apoptotic agent, such as surviving in protecting ovarian follicles against cell death. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti%20apoptotic%20drug" title="anti apoptotic drug">anti apoptotic drug</a>, <a href="https://publications.waset.org/abstracts/search?q=bitches" title=" bitches"> bitches</a>, <a href="https://publications.waset.org/abstracts/search?q=follicles" title=" follicles"> follicles</a>, <a href="https://publications.waset.org/abstracts/search?q=Z-VAD-FMK" title=" Z-VAD-FMK"> Z-VAD-FMK</a> </p> <a href="https://publications.waset.org/abstracts/56568/effect-of-z-vad-fmk-on-in-vitro-viability-of-dog-follicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56568.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">361</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">5920</span> Coagulase Negative Staphylococci: Phenotypic Characterization and Antimicrobial Susceptibility Pattern</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lok%20Bahadur%20Shrestha">Lok Bahadur Shrestha</a>, <a href="https://publications.waset.org/abstracts/search?q=Narayan%20Raj%20Bhattarai"> Narayan Raj Bhattarai</a>, <a href="https://publications.waset.org/abstracts/search?q=Basudha%20Khanal"> Basudha Khanal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Coagulase-negative staphylococci (CoNS) are the normal commensal of human skin and mucous membranes. The study was carried out to study the prevalence of CoNS among clinical isolates, to characterize them up to species level and to compare the three conventional methods for detection of biofilm formation. Objectives: to characterize the clinically significant coagulase-negative staphylococci up to species level, to compare the three phenotypic methods for the detection of biofilm formation and to study the antimicrobial susceptibility pattern of the isolates. Methods: CoNS isolates were obtained from various clinical samples during the period of 1 year. Characterization up to species level was done using biochemical test and study of biofilm formation was done by tube adherence, congo red agar, and tissue culture plate method. Results: Among 71 CoNS isolates, seven species were identified. S. epidermidis was the most common species followed by S. saprophyticus, S. haemolyticus. Antimicrobial susceptibility pattern of CoNS documented resistance of 90% to ampicillin. Resistance to cefoxitin and ceftriaxone was observed in 55% of the isolates. We detected biofilm formation in 71.8% of isolates. The sensitivity of tube adherence method was 82% while that of congo red agar method was 78%. Conclusion: Among 71 CoNS isolated, S. epidermidis was the most common isolates followed by S. saprophyticus and S. haemolyticus. Biofilm formation was detected in 71.8% of the isolates. All of the methods were effective at detecting biofilm-producing CoNS strains. Biofilm former strains are more resistant to antibiotics as compared to biofilm non-formers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CoNS" title="CoNS">CoNS</a>, <a href="https://publications.waset.org/abstracts/search?q=congo%20red%20agar" title=" congo red agar"> congo red agar</a>, <a href="https://publications.waset.org/abstracts/search?q=bloodstream%20infections" title=" bloodstream infections"> bloodstream infections</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20body-related%20infections" title=" foreign body-related infections"> foreign body-related infections</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20culture%20plate" title=" tissue culture plate "> tissue culture plate </a> </p> <a href="https://publications.waset.org/abstracts/77219/coagulase-negative-staphylococci-phenotypic-characterization-and-antimicrobial-susceptibility-pattern" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77219.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">198</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">5919</span> Investigation of Astrocyte Physiology on Stiffness-Controlled Cellulose Acetate Nanofiber as a Tissue Scaffold</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20Il%20Yu">Sun Il Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Hyun%20Joo"> Jung Hyun Joo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwa%20Sung%20Shin"> Hwa Sung Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Astrocytes are known as dominant cells in CNS and play a role as a supporter of CNS activity and regeneration. Recently, three-dimensional culture of astrocytes were actively applied to understand in vivo astrocyte works. Electrospun nanofibers are attractive for 3D cell culture system because they have a high surface to volume ratio and porous structure, and have already been used for 3D astrocyte cultures. In this research, the stiffness of cellulose acetate (CA) nanofiber was controlled by heat treatment. As stiffness increased, astrocyte cell viability and adhesion increased. Reactivity of astrocyte was also upregulated in stiffer CA nanofiber in terms of GFAP, an intermediate filament protein.

The quadrilateral plate elements include the 4-node conforming plate element based on the classical laminate plate theory (CLPT), the 4-node and 9-node Mindlin plate element based on the first-order shear deformation laminated plate theory (FSDT), and a displacement-based 4-node quadrilateral element (RDKQ-NL20). Using the von-Karman’s large deflection theory and the total Lagrangian (TL) approach, the nonlinear FE governing equations for plate under thermal load are derived. Convergence analysis for four elements is first conducted. These elements are then used to predict the stable shapes of thermally-induced bistable plate. Numerical test shows that the plate element based on FSDT, namely the 4-node and 9-node Mindlin, and the RDKQ-NL20 plate element can predict two stable cylindrical shapes while the 4-node conforming plate predicts a saddles shape. Comparing the simulation results with ABAQUS, the RDKQ-NL20 element shows the best accuracy among all the elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bistable" title="Bistable">Bistable</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=geometrical%20nonlinearity" title=" geometrical nonlinearity"> geometrical nonlinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrilateral%20plate%20elements" title=" quadrilateral plate elements"> quadrilateral plate elements</a> </p> <a href="https://publications.waset.org/abstracts/124454/finite-element-analysis-of-thermally-induced-bistable-plate-using-four-plate-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124454.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">220</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">5917</span> Numerical Analysis of Dynamic Responses of the Plate Subjected to Impulsive Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Mohammadzadeh">Behzad Mohammadzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Huyk%20Chun%20Noh"> Huyk Chun Noh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The plate is one of the popular structural elements used in a wide range of industries and structures. They may be subjected to blast loads during explosion events, missile attacks or aircraft attacks. This study is to investigate dynamic responses of the rectangular plate subjected to explosive loads. The effects of material properties and plate thickness on responses of the plate are to be investigated. The compressive pressure is applied to the surface of the plate. Different amounts of thickness in the range from 10mm to 30mm are considered for the plate to evaluate the changes in responses of the plate with respect to the plate thickness. Two different properties are considered for the steel. First, the analysis is performed by considering only the elastic-plastic properties for the steel plate. Later on damping is considered to investigate its effects on the responses of the plate. To do analysis, the numerical method using a finite element based package ABAQUS is applied. Finally, dynamic responses and graphs showing the relation between maximum displacement of the plate and aim parameters are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impulsive%20loaded%20plates" title="impulsive loaded plates">impulsive loaded plates</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20analysis" title=" dynamic analysis"> dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ABAQUS" title=" ABAQUS"> ABAQUS</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20nonlinearity" title=" material nonlinearity"> material nonlinearity</a> </p> <a href="https://publications.waset.org/abstracts/28535/numerical-analysis-of-dynamic-responses-of-the-plate-subjected-to-impulsive-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28535.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">523</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">5916</span> Molecular Analysis of Somaclonal Variation in Tissue Culture Derived Bananas Using MSAP and SSR Marker</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emma%20K.%20Sales">Emma K.

Moreover, the utility of molecular markers (SSR and MSAP) in sorting off types/somaclones were investigated. Results show that somaclonal variation is in effect due to prolonged subculture and high 2,4-D concentration. The resultant variation was observed to be due to high level of methylation events specifically cytosine methylation either at the internal or external cytosine and was identified by methylation sensitive amplification polymorphism (MSAP). Simple sequence repeats (SSR) on the other hand, was able to associate a marker to a trait of interest. These therefore, show that molecular markers can be an important tool in sorting out variation/mutants at an early stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methylation" title="methylation">methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=MSAP" title=" MSAP"> MSAP</a>, <a href="https://publications.waset.org/abstracts/search?q=somaclones" title=" somaclones"> somaclones</a>, <a href="https://publications.waset.org/abstracts/search?q=SSR" title=" SSR"> SSR</a>, <a href="https://publications.waset.org/abstracts/search?q=subculture" title=" subculture"> subculture</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title=" 2"> 2</a>, <a href="https://publications.waset.org/abstracts/search?q=4-D" title="4-D">4-D</a> </p> <a href="https://publications.waset.org/abstracts/6604/molecular-analysis-of-somaclonal-variation-in-tissue-culture-derived-bananas-using-msap-and-ssr-marker" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6604.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">301</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">5915</span> Aerodynamic Sound from a Sawtooth Plate with Different Thickness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Ruhliah%20Lizarose%20Samion">Siti Ruhliah Lizarose Samion</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sukri%20Mat%20Ali"> Mohamed Sukri Mat Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of sawtooth plate thickness on the aerodynamic noise generated in flow at a Reynolds number of 150 is numerically investigated. Two types of plate thickness (hthick=0.2D and hthin=0.02D) are proposed. Flow simulations are carried out using Direct Numerical Simulation, whereas the calculation of aerodynamic noise radiated from the flow is solved using Curle’s equation. It is found that the flow behavior of thin sawtooth plate, consisting counter-rotating-vortices, is more complex than that of the thick plate. This then explains well the generated sound in both plates cases. Sound generated from thin plat is approximately 0.5 dB lower than the thick plate. Findings from current study provide better understanding of the flow and noise behavior in edge serrations via understanding the case of a sawtooth plate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20sound" title="aerodynamic sound">aerodynamic sound</a>, <a href="https://publications.waset.org/abstracts/search?q=bluff%20body" title=" bluff body"> bluff body</a>, <a href="https://publications.waset.org/abstracts/search?q=sawtooth%20plate" title=" sawtooth plate"> sawtooth plate</a>, <a href="https://publications.waset.org/abstracts/search?q=Curle%20analogy" title=" Curle analogy"> Curle analogy</a> </p> <a href="https://publications.waset.org/abstracts/62349/aerodynamic-sound-from-a-sawtooth-plate-with-different-thickness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62349.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">436</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">5914</span> Application of Bioreactors in Regenerative Dentistry: Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20Malhotra">Neeraj Malhotra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Bioreactors in tissue engineering are used as devices that apply mechanical means to influence biological processes. They are commonly employed for stem cell culturing, growth and expansion as well as in 3D tissue culture. Contemporarily there use is well established and is tested extensively in the medical sciences, for tissue-regeneration and tissue engineering of organs like bone, cartilage, blood vessels, skin grafts, cardiac muscle etc. Methodology: Literature search, both electronic and hand search, was done using the following MeSH and keywords: bioreactors, bioreactors and dentistry, bioreactors & dental tissue engineering, bioreactors and regenerative dentistry. Articles published only in English language were included for review. Results: Bioreactors like, spinner flask-, rotating wall-, flow perfusion-, and micro-bioreactors and in-vivo bioreactor have been employed and tested for the regeneration of dental and like-tissues. These include gingival tissue, periodontal ligament, alveolar bone, mucosa, cementum and blood vessels. Based on their working dynamics they can be customized in future for regeneration of pulp tissue and whole tooth regeneration. Apart from this, they have been successfully used in testing the clinical efficacy and biological safety of dental biomaterials. Conclusion: Bioreactors have potential use in testing dental biomaterials and tissue engineering approaches aimed at regenerative dentistry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioreactors" title="bioreactors">bioreactors</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20process" title=" biological process"> biological process</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20stimulation" title=" mechanical stimulation"> mechanical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20dentistry" title=" regenerative dentistry"> regenerative dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cells" title=" stem cells"> stem cells</a> </p> <a href="https://publications.waset.org/abstracts/80359/application-of-bioreactors-in-regenerative-dentistry-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80359.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">209</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">5913</span> Effect of Operative Stabilization on Rib Fracture Healing in Porcine Experimental Model: A Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Stepankova">Maria Stepankova</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucie%20Vistejnova"> Lucie Vistejnova</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Klein"> Pavel Klein</a>, <a href="https://publications.waset.org/abstracts/search?q=Tereza%20Blassova"> Tereza Blassova</a>, <a href="https://publications.waset.org/abstracts/search?q=Marketa%20Slajerova"> Marketa Slajerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Radek%20Sedlacek"> Radek Sedlacek</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Bartos"> Martin Bartos</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaroslav%20Chlupac"> Jaroslav Chlupac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Clinical outcome benefits of the segment rib fracture surgical therapy are well known and follow from better stabilization of the chest wall. Despite this, some authors still incline to conservative therapy and point out to possible rib fracture healing failure in connection with the bone vascular supply disturbance caused by metal plate implantation. This suggestion met neither experimental nor clinical verification and remains the object of discussion. In our pilot study we investigated the titanium plate fixation effect on the rib fracture healing in porcine model and its histological, biomechanical and radiological aspects. Materials and Method: Two porcine models (experimental group) underwent the operative chest wall stabilization with a titanium plate implantation after osteotomy. Two other porcine models (control group) were treated conservatively after osteotomy. Three weeks after surgery, all animals were sacrificed, treated ribs were explanted and the histological analysis, µCT imaging and biomechanical testing of the calluses tissue were performed. Results: In µCT imaging, experimental group showed a higher cortical bone volume compared to the control group. Histological analysis using the non-decalcified bone tissue blocks demonstrated more maturated callus with higher newly-formed osseous tissue ratio in experimental group in comparison to controls. In contrast, no significant differences in bone blood vessels supply in both groups were observed. This finding suggests that the bone blood supply in experimental group was not impaired. Biomechanical analysis using 3-point bending test demonstrated significantly higher bending stiffness and the maximum force in experimental group. Conclusion: Based on our observation, it could be concluded, that the titanium plate fixation of the rib fractures leads to faster bone callus maturation whereas does not cause the vascular supply impairment after 3 weeks and thus has a beneficial effect on the rib fracture healing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20vascular%20supply" title="bone vascular supply">bone vascular supply</a>, <a href="https://publications.waset.org/abstracts/search?q=chest%20wall%20stabilization" title=" chest wall stabilization"> chest wall stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20healing" title=" fracture healing"> fracture healing</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20analysis" title=" histological analysis"> histological analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20plate%20implantation" title=" titanium plate implantation"> titanium plate implantation</a> </p> <a href="https://publications.waset.org/abstracts/121410/effect-of-operative-stabilization-on-rib-fracture-healing-in-porcine-experimental-model-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121410.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">141</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">5912</span> A Numerical Study on the Flow in a Pipe with Perforated Plates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myeong%20Hee%20Jeong">Myeong Hee Jeong</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> The use of perforated plate and tubes is common in applications such as vehicle exhaust silencers, attenuators in air moving ducts and duct linings in jet engines. Also, perforated plate flow conditioners designed to improve flow distribution upstream of an orifice plate flow meter typically have 50–60% free area but these generally employ a non-uniform distribution of holes of several sizes to encourage the formation of a fully developed pipe flow velocity distribution. In this study, therefore, numerical investigations on the flow characteristics with the various perforated plates have been performed and then compared to the case without a perforated plate. Three different models are adopted such as a flat perforated plate, a convex perforated plate in the direction of the inlet, and a convex perforated plate in the direction of the outlet. Simulation results show that the pressure drop with and without perforated plates are similar each other. However, it can be found that that the different shaped perforated plates influence the velocity contour, flow uniformity index, and location of the fully developed fluid flow. These results can be used as a practical guide to the best design of pipe with the perforated plate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perforated%20plate" title="perforated plate">perforated plate</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20uniformity" title=" flow uniformity"> flow uniformity</a>, <a href="https://publications.waset.org/abstracts/search?q=pipe%20turbulent%20flow" title=" pipe turbulent flow"> pipe turbulent flow</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20%28Computational%20Fluid%20Dynamics%29" title=" CFD (Computational Fluid Dynamics) "> CFD (Computational Fluid Dynamics) </a> </p> <a href="https://publications.waset.org/abstracts/23752/a-numerical-study-on-the-flow-in-a-pipe-with-perforated-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23752.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">691</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">5911</span> Suitability Evaluation of CNW as Scaffold for Osteoblast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoo%20Cheol%20Lee">Hoo Cheol Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae%20Seung%20Kim"> Dae Seung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Myung%20Jung"> Sang Myung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Gwang%20Heum%20Yoon"> Gwang Heum Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwa%20Sung%20Shin"> Hwa Sung Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Loss of bone tissue can occur due to a bone tissue disease and aging or fracture. Renewable formation of bone is mainly made by its differentiation and metabolism. For this reason, osteoblasts have been studied for regeneration of bone tissue. So, tissue engineering has attracted attention as a recovery means. In tissue engineering, a particularly important factor is a scaffold that supports cell growth. For osteoblast scaffold, we used the cellulose nanowhisker (CNW) extracted from marine organism. CNW is one of an abundant material obtained from a number of plants and animals. CNW is polymer consisting of monomer cellulose and this composition offers biodegradability and biocompatibility to CNW. Mechanical strength of CNW is superior to the existing natural polymers. In addition, substances of marine origin have a low risk of secondary infection by bacteria and pathogen in contrast with those of land-derived. For evaluating its suitability as an osteoblast scaffold, we fabricate CNW film for osteoblast culture and performed the MTT assay and ALP assay to confirm its cytotoxicity and effect on differentiation. Taking together these results, we assessed CNW is a potential candidate of a material for bone tissue regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20regeneration" title="bone regeneration">bone regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose%20nanowhisker" title=" cellulose nanowhisker"> cellulose nanowhisker</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20derived%20material" title=" marine derived material"> marine derived material</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title=" osteoblast"> osteoblast</a> </p> <a href="https://publications.waset.org/abstracts/7802/suitability-evaluation-of-cnw-as-scaffold-for-osteoblast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7802.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">347</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">5910</span> Comparative Study of Antioxidant Activity in in vivo and in vitro Samples of Purple Greater Yam (Dioscorea alata L).</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sakinah%20Abdullah">Sakinah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosna%20Mat%20Taha"> Rosna Mat Taha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species such as singlet oxygen, superoxide, peroxyl radicals, and peroxynitrite which result in oxidative stress leading to cellular damage. Natural antioxidant are in high demand because of their potential in health promotion and disease prevention and their improved safety and consumer acceptability. Plants are rich sources of natural antioxidant. Dioscorea alata L. known as 'ubi badak' in Malaysia were well known for their antioxidant content, but this plant was seasonal. Thus, tissue culture technique was used to mass propagate this plant. In the present work, a comparative study between in vitro (from tissue culture) and in vivo (from intact plant) samples of Dioscorea alata L. for their antioxidant potential by 2,2-diphenil -1- picrylhydrazyl (DPPH) radical scavenging activity method and their total phenolic and flavonoid contents were carried out. All samples had better radical scavenging activity but in vivo samples had the strongest radical scavenging activity compared to in vitro samples. Furthermore, tubers from in vivo samples showed the greatest free radical scavenging effect and comparatively greater phenolic content than in vitro samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dioscorea%20alata" title="Dioscorea alata">Dioscorea alata</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20culture" title=" tissue culture"> tissue culture</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vivo" title=" in vivo"> in vivo</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro" title=" in vitro"> in vitro</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH" title=" DPPH"> DPPH</a> </p> <a href="https://publications.waset.org/abstracts/31969/comparative-study-of-antioxidant-activity-in-in-vivo-and-in-vitro-samples-of-purple-greater-yam-dioscorea-alata-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31969.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">470</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">5909</span> Bacteriological Culture Methods and its Uses in Clinical Pathology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prachi%20Choudhary">Prachi Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Gopal%20Sharma"> Jai Gopal Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbial cultures determine the type of organism, its abundance in the tested sample, or both. It is one of the primary diagnostic methods of microbiology. It is used to determine the cause of infectious disease by letting the agent multiply in a predetermined medium. Different bacteria produce colonies that may be very distinct from the bacterial species that produced them. To culture any pathogen or microorganism, we should first know about the types of media used in microbiology for culturing. Sometimes sub culturing is also done in various microorganisms if some mixed growth is seen in culture. Nearly 3 types of culture media based on consistency – solid, semi-solid, and liquid (broth) media; are further explained in the report. Then, The Five I's approach is a method for locating, growing, observing, and characterizing microorganisms, including inoculation and incubation. Isolation, inspection, and identification. For identification of bacteria, we have to culture the sample like urine, sputum, blood, etc., on suitable media; there are different methods of culturing the bacteria or microbe like pour plate method, streak plate method, swabbing by needle, pipetting, inoculation by loop, spreading by spreader, etc. After this, we see the bacterial growth after incubation of 24 hours, then according to the growth of bacteria antibiotics susceptibility test is conducted; this is done for sensitive antibiotics or resistance to that bacteria, and also for knowing the name of bacteria. Various methods like the dilution method, disk diffusion method, E test, etc., do antibiotics susceptibility tests. After that, various medicines are provided to the patients according to antibiotic sensitivity and resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inoculation" title="inoculation">inoculation</a>, <a href="https://publications.waset.org/abstracts/search?q=incubation" title=" incubation"> incubation</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics%20suspectibility%20test" title=" antibiotics suspectibility test"> antibiotics suspectibility test</a>, <a href="https://publications.waset.org/abstracts/search?q=characterizing" title=" characterizing"> characterizing</a> </p> <a href="https://publications.waset.org/abstracts/161272/bacteriological-culture-methods-and-its-uses-in-clinical-pathology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161272.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">82</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">5908</span> Stability of Square Plate with Concentric Cutout</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20S.%20Jayashankarbabu">B.

This study was done to determine different reactions of the temperatures in different depths of brain tissue in confronting with radiofrequency waves of cell phones. Methodology: This study was an empirical research. A cow's brain tissue was placed in a compartment and the effects of radiofrequency waves of the cell phone was analyzed during confrontation and after confrontation, in three different depths of 2, 12, and 22 mm of the tissue, in 4 mm and 4 cm distances of the tissue to a cell phone, for 15 min. Lutron thermometer was used to measure the tissue temperatures. Data analysis was done by Lutron software. Findings: The rate of increasing the temperature at the depth of 22 mm was higher than 2 mm and 12mm depths, during confrontation of the brain tissue at the distance of 4 mm with the cell phone, such that the tissue temperatures at 2, 12, and 22 mm depths increased by 0.29 ˚C, 0.31 ˚C, and 0.37 ˚C, respectively, relative to the base temperature (tissue temperature before confrontation). Moreover, the temperature of brain tissue at the distance of 4 cm by increasing the tissue depth was more than other depths. Increasing the tissue temperature also existed by increasing the brain tissue depth after the confrontation with the cell phone. The temperature of the 22 mm depth increased with higher speed at the time confrontation. Conclusion: Not only radiofrequency waves of cell phones increased the tissue temperature in all the depths of the brain tissue, but also the temperature due to radiofrequency waves of the cell phone was more at the depths higher than 22 mm of the tissue. In fact, the thermal effect of radiofrequency waves was higher in higher depths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20phone" title="mobile phone">mobile phone</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20waves" title=" radio frequency waves"> radio frequency waves</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20tissue" title=" brain tissue"> brain tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/98613/exposure-to-radio-frequency-waves-of-mobile-phone-and-temperature-changes-of-brain-tissue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98613.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">201</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">5904</span> Repair of Cracked Aluminum Plate by Composite Patch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Lecheb">S.

The dynamic analysis in the present work covered parametric studies on a composite laminated plate (square plate) to determine its effect on the natural frequency of the plate. The parametric study is represented by set of changes (plate thickness, number of layers, support conditions, layer orientation), and the plates have been simulated by using ANSYS package 12. The boundary conditions considered in this study, at all four edges of the plate, are simply supported and fixed boundary condition. The results obtained from ANSYS program show that the natural frequency for both fixed and simply supported increases with increasing the number of layers, but this increase in the natural frequency for the first five modes will be neglected after 10 layers. And it is observed that the natural frequency of a composite laminated plate will change with the change of ply orientation, the natural frequency increases and it will be at maximum with angle 45 of ply for simply supported laminated plate, and maximum natural frequency will be with cross-ply (0/90) for fixed laminated composite plate. It is also observed that the natural frequency increase is approximately doubled when the thickness is doubled. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminated%20plate" title="laminated plate">laminated plate</a>, <a href="https://publications.waset.org/abstracts/search?q=orthotropic%20plate" title=" orthotropic plate"> orthotropic plate</a>, <a href="https://publications.waset.org/abstracts/search?q=square%20plate" title=" square plate"> square plate</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency%20%28free%20vibration%29" title=" natural frequency (free vibration)"> natural frequency (free vibration)</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20%28graphite%20%2F%20epoxy%29" title=" composite (graphite / epoxy)"> composite (graphite / epoxy)</a> </p> <a href="https://publications.waset.org/abstracts/63332/parametric-study-on-dynamic-analysis-of-composite-laminated-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63332.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">348</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">5902</span> Effect of Welding Parameters on Penetration and Bead Width for Variable Plate Thickness in Submerged Arc Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harish%20K.%20Arya">Harish K.

In a conventional cell culture, trypsinization was employed for cell detachment. However, trypsinization causes proliferation decrease due to injury of cell membrane. In order to detach cells using an enzyme-free method, therefore, this study proposes a novel cell detachment method capable of detaching adherent cells using acoustic radiation pressure exposed to the dish by the assistance of serum-free medium with ITS liquid medium supplement. Methods used In order to generate acoustic radiation pressure, a piezoelectric ceramic plate was glued on a glass plate to configure an ultrasonic transducer. The glass plate and a chamber wall compose a chamber in which a culture dish is placed in glycerol. Glycerol transmits acoustic radiation pressure to adhered cells on the culture dish. To excite a resonance vibration of transducer, AC signal with 29-31 kHz (swept) and 150, 300, and 450 V was input to the transducer for 5 min. As a pretreatment to reduce cell adhesivity, serum-free medium with ITS liquid medium supplement was spread to the culture dish before exposed to acoustic radiation pressure. To evaluate the proposed cell detachment method, C2C12 myoblast cells (8.0 × 104 cells) were cultured on a ø35 culture dish for 48 hr, and then the medium was replaced with the serum-free medium with ITS liquid medium supplement for 24 hr. We replaced the medium with phosphate buffered saline and incubated cells for 10 min. After that, cells were exposed to the acoustic radiation pressure for 5 min. We also collected cells by using trypsinization as control. Cells collected by the proposed method and trypsinization were respectively reseeded in ø60 culture dishes and cultured for 24 hr. Then, the number of proliferated cells was counted. Results achieved: By a phase contrast microscope imaging, shrink of lamellipodia was observed before exposed to acoustic radiation pressure, and no cells remained on the culture dish after the exposed of acoustic radiation pressure. This result suggests that serum-free medium with ITS liquid inhibits adhesivity of cells and acoustic radiation pressure detaches cells from the dish. Moreover, the number of proliferated cells 24 hr after collected by the proposed method with 150 and 300 V is the same or more than that by trypsinization, i.e., cells were proliferated 15% higher with the proposed method using acoustic radiation pressure than with the traditional cell collecting method of trypsinization. These results proved that cells were able to be collected by using the appropriate exposure of acoustic radiation pressure. Conclusions: This study proposed a cell detachment method using acoustic radiation pressure by the assistance of serum-free medium. The proposed method provides an enzyme-free cell detachment method so that it may be used in future clinical applications instead of trypsinization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20radiation%20pressure" title="acoustic radiation pressure">acoustic radiation pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20detachment" title=" cell detachment"> cell detachment</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20free" title=" enzyme free"> enzyme free</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20transducer" title=" ultrasonic transducer"> ultrasonic transducer</a> </p> <a href="https://publications.waset.org/abstracts/61227/acoustic-radiation-pressure-detaches-myoblast-from-culture-substrate-by-assistance-of-serum-free-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61227.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">254</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">5899</span> Parameters Optimization of the Laminated Composite Plate for Sound Transmission Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20T.%20Tsai">Yu T.

The transfer matrix approach is novelty presented for computational efficiency in solving the numerous layers of dynamic stiffness matrix (D-matrix) of the LCP. Besides the numerical simulations for calculating the TL of the LCP, the material properties inverse method is presented for the design of a laminated composite plate analogous to a metallic plate with a specified TL.

Wallich ex. Nees (Family Acanthaceae) popularly known as King of Bitters, is an important medicinal herb. It has an astonishingly wide range of medicinal properties such as anti-inflammatory,antidiarrhoeal, antiviral, antimalarial, hepatoprotective, cardiovascular, anticancer, and immunostimulatory activities. It is widely cultivated in southern Asia. Though propagation of this herb generally occurs through seeds, it has many germination problems which intrigued scientists to work out on the alternative techniques for its mass production. The potential of tissue culture techniques as an alternative tool for AP multiplication was found to be promising. However, the high mortality rate of explants caused by phenolic browning of explants is one of the difficulties reported. Low multiplication rates were reported in the proliferation phase, as well as cultures decline characterized by leaf fall and loss of overall vigor. In view of above problems, a study was undertaken to overcome seed dormancy to improve germination potential and to investigate further on the possible means for successful proliferation of cultures via preventive approaches to overcome failures caused by phenolic browning. Experiments were conducted to improve germination potential and among all the chemical and mechanical trials, scarification of seeds with sand paper proved to be the best method to enhance the germination potential (82.44%) within 7 days. Similarly, several pretreatments and media combinations were tried to overcome browning of explants leading to the conclusion that addition of 0.1% citric acid and 0.2% of ascorbic acid in the media followed by rapid sub culturing of explants controlled browning and decline of explants by 67.45%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant%20tissue%20culture" title="plant tissue culture">plant tissue culture</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20measure" title=" empirical measure"> empirical measure</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20culture" title=" tissue culture"> tissue culture</a> </p> <a href="https://publications.waset.org/abstracts/15545/empirical-measures-to-enhance-germination-potential-and-control-browning-of-tissue-cultures-of-andrographis-paniculata" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15545.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">414</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">5897</span> Inflammatory Changes Caused by Lipopolysaccharide in Odontoblasts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Virve%20P%C3%A4%C3%A4kk%C3%B6nen">Virve Pääkkönen</a>, <a href="https://publications.waset.org/abstracts/search?q=Heidi%20M.%20Cuffaro"> Heidi M.

Importance of bacterial products, e.g. lipoteichoic acid (LTA), a cell wall component of Gram-positive bacteria and lipopolysaccharide (LPS), a cell wall component of Gram-negative bacteria, have been indicated in the pathogenesis of pulpitis. Gram-positive bacteria are more prevalent in superficial carious lesion while the amount gram-negative is higher in the deep lesions. Objective of this study was to investigate the effect of these bacterial products on inflammatory response of pulp tissue. Interleukins (IL) were of special interest. Various ILs have been observed in the dentin-pulp complex of carious tooth in vivo. Methods: Tissue culture method was used for testing the effect of LTA and LPS on human odontoblasts. Enzymatic isolation technique was used to extract living odontoblasts for cell cultures. DNA microarray and quantitative PCR (qPCR) were used to characterize the changes in the expression profile of the tissue cultured odontoblasts. Laser microdissection was used to cut healthy and affected dentin and odontoblast layer directly under carious lesion for experiments. Cytokine array detecting 80 inflammatory cytokines was used to analyze the protein content of conditioned culture media as well as dentin and odontoblasts from the carious teeth. Results: LPS caused increased gene expression IL-1α, and -8 and decrease of IL-1β, 12 , -15 and -16 after 1h treatment, while after 24h treatment decrease of IL-8, -11 and 23 mRNAs was observed. LTA treatment caused cell death in the tissue cultured odontoblasts but in in the cell culture but not in cell culture. Cytokine array revealed at least 2-fold down-regulation of IL-1β, -10 and -12 in response to LPS treatment. Cytokine array of odontoblasts of carious teeth, as well as LPS-treated tissue-cultured odontoblasts, revealed increased protein amounts of IL-16, epidermal growth factor (EGF), angiogenin and IGFBP-1 as well as decreased amount of fractalkine. In carious dentin, increased amount of IL-1β, EGF and fractalkine was observed, as well as decreased level of GRO-1 and HGF. Conclusion: LPS caused marked changes in the expression of inflammatory cytokines in odontoblasts. Similar changes were observed in the odontoblasts cut directly under the carious lesion. These results help to shed light on the inflammatory processes happening during caries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammation" title="inflammation">inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin" title=" interleukin"> interleukin</a>, <a href="https://publications.waset.org/abstracts/search?q=lipoteichoic%20acid" title=" lipoteichoic acid"> lipoteichoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=odontoblasts" title=" odontoblasts"> odontoblasts</a> </p> <a href="https://publications.waset.org/abstracts/55956/inflammatory-changes-caused-by-lipopolysaccharide-in-odontoblasts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55956.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">211</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">5896</span> Free Vibration and Buckling of Rectangular Plates under Nonuniform In-Plane Edge Shear Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20H.%20Young">T.

Nanobioactive glass has been synthesized by sol gel method having a combination of silicon, calcium and phosphorous in the molar ratio of 75:21:4. The prepared particles were analyzed for surface morphology by FEG SEM and FEG TEM. Physiochemical properties were investigated using ICP AES, FTIR spectroscopy and X-ray diffraction (XRD) techniques. To ascertain their use for therapeutic use, biocompatibility evaluation of the particles was done by performing soaking studies in SBF and in vitro cell culture studies on MG63 cell lines. Cell morphology was observed by FE SEM and phase contrast microscopy. Nanobioactive glasses (NBG) thus prepared were of 30-200 nm in size, which makes them suitable for nano-biomedical applications. The spherical shape of the particles imparts high surface to volume ratio, promoting fast growth of hydroxyapatite (HA), which is the mineral component of bone. As evaluated by in vitro cell culture studies the NBG was found to enhance the surface activation which enhances osteoblast adhesion. This is an essential parameter to improve bone tissue integration, thereby making nanobioactive glass therapeutically suitable for correcting bone defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title=" bone tissue engineering"> bone tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=nanobioactive%20glass" title=" nanobioactive glass"> nanobioactive glass</a> </p> <a href="https://publications.waset.org/abstracts/14477/preparation-and-application-of-biocompatible-nanobioactive-glass-as-therapeutic-agents-for-bone-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14477.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">456</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">5894</span> A CMOS-Integrated Hall Plate with High Sensitivity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Sup%20Kim">Jin Sup Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Seo"> Min Seo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An improved cross-shaped hall plate with high sensitivity is described in this paper. Among different geometries that have been simulated and measured using Helmholtz coil. The paper describes the physical hall plate design and implementation in a 0.18-µm CMOS technology. In this paper, the biasing is a constant voltage mode. In the voltage mode, magnetic field is converted into an output voltage. The output voltage is typically in the order of micro- to millivolt and therefore, it must be amplified before being transmitted to the outside world. The study, design and performance optimization of hall plate has been carried out with the COMSOL Multiphysics. It is used to estimate the voltage distribution in the hall plate with and without magnetic field and to optimize the geometry. The simulation uses the nominal bias current of 1mA. The applied magnetic field is in the range from 0 mT to 20 mT. Measured results of the one structure over the 10 available samples show for the best sensitivity of 2.5 %/T at 20mT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-shaped%20hall%20plate" title="cross-shaped hall plate">cross-shaped hall plate</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=CMOS%20technology" title=" CMOS technology"> CMOS technology</a>, <a href="https://publications.waset.org/abstracts/search?q=Helmholtz%20coil" title=" Helmholtz coil"> Helmholtz coil</a> </p> <a href="https://publications.waset.org/abstracts/79041/a-cmos-integrated-hall-plate-with-high-sensitivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79041.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">197</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">5893</span> Design and Fabrication of a Scaffold with Appropriate Features for Cartilage Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20S.%20Salehi">S.

An artificial tissue should have some features such as biocompatibility, biodegradation and, enough mechanical properties like the original tissue. In this work, a composite hydrogel is prepared by using natural and synthetic materials that has high porosity. Mechanical properties of different combinations of polymers such as modulus of elasticity were tested, and a hydrogel with good mechanical properties was selected. Bone marrow derived mesenchymal stem cells were also seeded into the pores of the sponge, and the results showed the adhesion and proliferation of cells within the hydrogel after one month. In comparison with previous works, this study offers a new and efficient procedure for the fabrication of cartilage like tissue and further cartilage repair. <p
