Despite different treatments and surgery, recurrence of glioblastoma cancer stem cells may arise as a subsequent tumor. For this reason, it is crucial to research the markers associated with glioblastoma stem cells and specifically their microenvironment. In this study, using bioinformatics analysis, we analyzed and nominated genes in the microenvironment pathways of glioblastoma stem cells. In this study, an appropriate database was selected for analysis by referring to the GEO database. This dataset comprised gene expression patterns in stem cells derived from glioblastoma patients. Gene clusters were divided as high and low expression. Enrichment databases such as Enrichr, STRING, and GEPIA were utilized to analyze the data appropriately. Finally, we extracted the potential genes 2700 high-expression and 1100 low-expression genes are implicated in the metabolic pathways of glioblastoma cancer progression. Cellular senescence, MAPK, TNF, hypoxia, zimosterol biosynthesis, and phosphatidylinositol metabolism pathways were substantially expressed and the metabolic pathways were downregulated. After assessing the association between protein networks, MSMP, SOX2, FGD4 ,and CNTNAP3 genes with high expression and DMKN and SBSN genes with low were selected. All of these genes were observed in the survival curve, with a survival of fewer than 10 percent over around 15 months. hsa-mir-192-5p, hsa-mir-129-5p, hsa-mir-215-5p, hsa-mir-335-5p, and hsa-mir-340-5p played key function in glioblastoma cancer stem cells microenviroments. We introduced critical genes through integrated and regular bioinformatics studies by assessing the amount of gene expression profile data that can play an important role in targeting genes involved in the energy and microenvironment of glioblastoma cancer stem cells. Have. This study indicated that hsa-mir-192-5p, and hsa-mir-129-5p are appropriate candidates for this. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glioblastoma" title="Glioblastoma">Glioblastoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Cancer%20Stem%20Cells" title="Cancer Stem Cells">Cancer Stem Cells</a>, <a href="https://publications.waset.org/abstracts/search?q=Biomarker%20Discovery" title="Biomarker Discovery">Biomarker Discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=Gene%20Expression%20Profiles" title="Gene Expression Profiles">Gene Expression Profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=Bioinformatics%20Analysis" title="Bioinformatics Analysis">Bioinformatics Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Tumor%20Microenvironment" title="Tumor Microenvironment">Tumor Microenvironment</a> </p> <a href="https://publications.waset.org/abstracts/147739/hsa-mir-192-5p-and-hsa-mir-129-5p-prominent-biomarkers-in-regulation-glioblastoma-cancer-stem-cells-genes-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147739.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">144</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">3030</span> Protective Potential of Hyperhalophilic Diatoms Extract Against Lead Induced Oxidative Stress in Rats and Human HepG2 and HEK293 Cells Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wassim%20Guermazi">Wassim Guermazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saoussan%20Boukhris"> Saoussan Boukhris</a>, <a href="https://publications.waset.org/abstracts/search?q=Neila%20Annabi%20Trabelsi"> Neila Annabi Trabelsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Rebai"> Tarek Rebai</a>, <a href="https://publications.waset.org/abstracts/search?q=Alya%20Sellami-Kamoun"> Alya Sellami-Kamoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Ayadi"> Habib Ayadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigates the protective effects of the microalga Halamphora sp. extract (H. Ext) as a natural product on lead-intoxicated liver and kidney human cells in vitro and in vivo on rats wistar. HepG2 cells line derived from human hepatocellular carcinoma and HEK293 cells line derived from human embryonic kidney were used for the in vitro study. The analysis of the fatty acids methyl esters of the extract was performed by a GC/MS. Four groups of rats, each of which was composed of six animals, were used for the in vivo experiment. The pretreatment of HepG2 and HEK293 cells line with the extract (100 µg mL-1) significantly (p < 0.05) protected against cytotoxicity induced by lead exposure. In vivo, the biochemical parameters in serum, namely malondialdehyde level (MDA), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities, were measured in supernatants of organ homogenates. H. Ext was found to be rich in fatty acids, essentially palmitic and palmitoleic accounting respectively 29.46% and 42.07% of total fatty acids. Both in vitro and in vivo, the co-treatment with H. Ext allowed the protection of the liver and kidney cells structure, as well as the significant preservation of normal antioxidant and biochemical parameters in rats. Halamphora extract rich in fatty acids has been proven to be effective in protection against Pb-induced toxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalga%20extract" title="microalga extract">microalga extract</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20cells%20line" title=" human cells line"> human cells line</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title=" fatty acid"> fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20exposure" title=" lead exposure"> lead exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a> </p> <a href="https://publications.waset.org/abstracts/163424/protective-potential-of-hyperhalophilic-diatoms-extract-against-lead-induced-oxidative-stress-in-rats-and-human-hepg2-and-hek293-cells-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163424.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">88</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">3029</span> Analysis of Anti-Tuberculosis Immune Response Induced in Lungs by Intranasal Immunization with Mycobacterium indicus pranii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ananya%20Gupta">Ananya Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeeta%20Bhaskar"> Sangeeta Bhaskar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycobacterium indicus pranii (MIP) is a saprophytic mycobacterium. It is a predecessor of M. avium complex (MAC). Whole genome analysis and growth kinetics studies have placed MIP in between pathogenic and non-pathogenic species. It shares significant antigenic repertoire with M. tuberculosis and have unique immunomodulatory properties. MIP provides better protection than BCG against pulmonary tuberculosis in animal models. Immunization with MIP by aerosol route provides significantly higher protection as compared to immunization by subcutaneous (s.c.) route. However, mechanism behind differential protection has not been studied. In this study, using mice model we have evaluated and compared the M.tb specific immune response in lung compartments (airway lumen / lung interstitium) as well as spleen following MIP immunization via nasal (i.n.) and s.c. route. MIP i.n. vaccination resulted in increased seeding of memory T cells (CD4+ and CD8+ T-cells) in the airway lumen. Frequency of CD4+ T cells expressing Th1 migratory marker (CXCR3) and activation marker (CD69) were also high in airway lumen of MIP i.n. group. Significantly high ex vivo secretion of cytokines- IFN-, IL-12, IL-17 and TNF- from cells of airway luminal spaces provides evidence of antigen-specific lung immune response, besides generating systemic immunity comparable to MIP s.c. group. Analysis of T cell response on per cell basis revealed that antigen specific T-cells of MIP i.n. group were functionally superior as higher percentage of these cells simultaneously secreted IFN-gamma, IL-2 and TNF-alpha cytokines as compared to MIP s.c. group. T-cells secreting more than one of the cytokines simultaneously are believed to have robust effector response and crucial for protection, compared with single cytokine secreting T-cells. Adoptive transfer of airway luminal T-cells from MIP i.n. group into trachea of naive B6 mice revealed that MIP induced CD8 T-cells play crucial role in providing long term protection. Thus the study demonstrates that MIP intranasal vaccination induces M.tb specific memory T-cells in the airway lumen that results in an early and robust recall response against M.tb infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20lumen" title="airway lumen">airway lumen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20indicus%20pranii" title=" Mycobacterium indicus pranii"> Mycobacterium indicus pranii</a>, <a href="https://publications.waset.org/abstracts/search?q=Th1%20migratory%20markers" title=" Th1 migratory markers"> Th1 migratory markers</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccination" title=" vaccination"> vaccination</a> </p> <a href="https://publications.waset.org/abstracts/84568/analysis-of-anti-tuberculosis-immune-response-induced-in-lungs-by-intranasal-immunization-with-mycobacterium-indicus-pranii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84568.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">187</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">3028</span> Radix Saposhnikoviae Suppresses Allergic Contact Dermatitis in Mice by Regulating DCs Activated Th1-Type Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hailiang%20Liu">Hailiang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Ni"> Yan Ni</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zheng"> Jie Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoyan%20Jiang"> Xiaoyan Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Hong"> Min Hong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Allergic contact dermatitis (ACD) is a commonly clinical type IV allergic skin disease, with the pathological features of infiltration by mononuclear cells and tissue necrosis. Traditional Chinese medicine Radix Saposhnikoviae (RS) is traditionally employed to treat exogenous evils, rubella, itching, rheumatism and tetanus. Meanwhile, it is an important component of the commonly used anti-allergy compound. It’s now widely used as an immuno-modulating agent in mixed herbal decoctions to treat inflammation. However, its mechanism of anti-allergy remains unknown. RS was found to reduce ear thickness, as well as the infiltration of eosinophils. The proliferation of T lymphocytes was inhibited significantly by RS, markedly decreased IFN-γ levels in the supernatant of cells cultured and serum were detected with the treatment of RS. RS significantly decreased the amount of DCs in the mouse lymph nodes, and inhibited the expression of CD4 0 and CD86. Meanwhile, T-bet mRNA expression was down remarkably regulated by RS. These results indicate that RS cures Th1-induced allergic skin inflammation by regulating Th1/Th2 balance with decreasing Th1 differentiation, which might be associated with DCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergic%20contact%20dermatitis" title="allergic contact dermatitis">allergic contact dermatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=Radix%20saposhnikoviae" title=" Radix saposhnikoviae"> Radix saposhnikoviae</a>, <a href="https://publications.waset.org/abstracts/search?q=dendritic%20cells" title=" dendritic cells"> dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=T-bet" title=" T-bet"> T-bet</a>, <a href="https://publications.waset.org/abstracts/search?q=GATA-3" title=" GATA-3"> GATA-3</a>, <a href="https://publications.waset.org/abstracts/search?q=CD4%2B%20CD25%2B%20Foxp3%2B%20treg%20cells" title=" CD4+ CD25+ Foxp3+ treg cells "> CD4+ CD25+ Foxp3+ treg cells </a> </p> <a href="https://publications.waset.org/abstracts/3023/radix-saposhnikoviae-suppresses-allergic-contact-dermatitis-in-mice-by-regulating-dcs-activated-th1-type-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3023.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">374</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">3027</span> Survey of the Effect of the Probiotic Bacterium Lactobacillus plantarum and Streptococcus mutans on Casp3, AKT/PTEN, and MAPK Signaling Pathways at Co-Culture with KB Oral Cancer Cell Line and HUVEC Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Negar%20Zaheddoust">Negar Zaheddoust</a>, <a href="https://publications.waset.org/abstracts/search?q=Negin%20Zaheddoust"> Negin Zaheddoust</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Asoudeh-Fard"> Abbas Asoudeh-Fard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Probiotic bacteria have been employed as a novel and less side-effect strategy for anticancer therapy. Since the oral cavity is a host for probiotic and pathogen bacteria to colonize, more investigation is needed to evaluate the effectiveness of this novel adjunctive treatment for oral cancer. We considered Lactobacillus plantarum as a probiotic and Streptococcus mutans as a pathogen bacterium in our study. The aim of this study is to examine the effect of Lactobacillus plantarum and Streptococcus mutans on Casp3, AKT / PTEN, and MAPK signaling pathway, which is involved in apoptosis or survival of oral cancer KB cells. On the other hand, to study the effects of these bacteria on normal cells, we used HUVEC cells. The KB and HUVEC cell lines were co-cultured with Lactobacillus plantarum and Streptococcus mutans isolated from traditional Iranian dairy and dental plaque, respectively. The growth-inhibitory effects of these two bacteria on KB and HUVEC cells were determined by (3-(4, 5-dimethylthiazolyl-2)-2,5diphenyltetrazolium bromide) MTT assay. MTT results demonstrated that the proliferation of KB cells was affected in a time, dose, and strain-dependent manner. In the following, the examination of induced apoptosis or necrosis in co-cultured KB cells with the best IC50 concentration of the Lactobacillus plantarum and Streptococcus mutans will be analyzed by FACS flow cytometry, and the changes in gene expression of Casp3, AKT / PTEN, MAPK genes will be evaluated using real-time polymerase chain reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20therapy" title="cancer therapy">cancer therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=induced%20apoptosis" title=" induced apoptosis"> induced apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20cancer" title=" oral cancer"> oral cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a> </p> <a href="https://publications.waset.org/abstracts/140533/survey-of-the-effect-of-the-probiotic-bacterium-lactobacillus-plantarum-and-streptococcus-mutans-on-casp3-aktpten-and-mapk-signaling-pathways-at-co-culture-with-kb-oral-cancer-cell-line-and-huvec-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140533.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">248</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">3026</span> In silico Repopulation Model of Various Tumour Cells during Treatment Breaks in Head and Neck Cancer Radiotherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Loredana%20G.%20Marcu">Loredana G.

Treatment efficiency is often hindered by cancer cell repopulation during radiotherapy, which is due to various mechanisms triggered by the loss of tumour cells and involves both stem and differentiated cells. The aim of the current paper is to present in silico simulations of radiotherapy schedules on a virtual head and neck tumour grown with biologically realistic kinetic parameters. Using the linear quadratic formalism of cell survival after radiotherapy, altered fractionation schedules employing various treatment breaks for normal tissue recovery are simulated and repopulation mechanism implemented in order to evaluate the impact of various cancer cell contribution on tumour behaviour during irradiation. The model has shown that the timing of treatment breaks is an important factor influencing tumour control in rapidly proliferating tissues such as squamous cell carcinomas of the head and neck. Furthermore, not only stem cells but also differentiated cells, via the mechanism of abortive division, can contribute to malignant cell repopulation during treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiation" title="radiation">radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=tumour%20repopulation" title=" tumour repopulation"> tumour repopulation</a>, <a href="https://publications.waset.org/abstracts/search?q=squamous%20cell%20carcinoma" title=" squamous cell carcinoma"> squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell" title=" stem cell"> stem cell</a> </p> <a href="https://publications.waset.org/abstracts/17943/in-silico-repopulation-model-of-various-tumour-cells-during-treatment-breaks-in-head-and-neck-cancer-radiotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17943.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">267</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">3025</span> The Generation of Insulin Producing Cells from Human Mesenchymal Stem Cells by miR-375 and Anti-miR-9</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arefeh%20Jafarian">Arefeh Jafarian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taghikani"> Mohammad Taghikani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saied%20Abroun"> Saied Abroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Allahverdi"> Amir Allahverdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Soleimani"> Masoud Soleimani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The miRNAs have key roles in control of pancreatic islet development and insulin secretion. In this regards, current study investigated the pancreatic differentiation of human bone marrow mesenchymal stem cells (hBM-MSCs) by up-regulation of miR-375 and down-regulation of miR-9 by lentiviruses containing miR-375 and anti-miR-9. Findings: After 21 days of induction, islet-like clusters containing insulin producing cells (IPCs) were confirmed by dithizone (DTZ) staining. The IPCs and β cell specific related genes and proteins were detected using qRT-PCR and immunofluorescence on days 7, 14 and 21 of differentiation. Glucose challenge test was performed at different concentrations of glucose as well as extracellular and intracellular insulin and C-peptide were assayed using ELISA kit. In derived IPCs by miR-375 alone are capable to express insulin and other endocrine specific transcription factors, the cells lack the machinery to respond to glucose. The differentiated hMSCs by miR-375 and anti-miR-9 lentiviruses could secrete insulin and c-peptide in a glucose-regulated manner. Conclusion: It was found that over-expression of miR-375 led to a reduction in levels of Mtpn protein in derived IPCs, while treatment with anti-miR-9 following miR-375 over-expression had synergistic effects on MSCs differentiation and insulin secretion in a glucose-regulated manner. The researchers reported that silencing of miR-9 increased OC-2 protein in IPCs that may contribute to the observed glucose-regulated insulin secretion. These findings highlight miRNAs functions in stem cells differentiation and suggest that they could be used as therapeutic tools for gene-based therapy in diabetes mellitus. <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=differentiation" title=" differentiation"> differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=MSCs" title=" MSCs"> MSCs</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin%20producing%20cells" title=" insulin producing cells"> insulin producing cells</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-375" title=" miR-375"> miR-375</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-9" title=" miR-9 "> miR-9 </a> </p> <a href="https://publications.waset.org/abstracts/31158/the-generation-of-insulin-producing-cells-from-human-mesenchymal-stem-cells-by-mir-375-and-anti-mir-9" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31158.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">317</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">3024</span> Ancelim: Health System Restoration Protocol for Cancer Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Berry">Mark Berry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A number of studies have identified several factors involved in the malignant progression of cancer cells. The Primary modulator in driving inflammation to these transformed cells has been identified as the transcription factor known as nuclear factor-κB. This essential regulator of inflammation and the development of cancer, combined with a microenvironment of inflammation and signaling molecules, plays a major role in the malignant progression of cancer, and this progression is the result of the mutagenic predisposition of persistent substances that combat infection at tumor sites and other areas of chronic inflammation. Inflammation-induced tumors, and their inflammatory cells and regulators may be the primary source of metastasis of tumor cells through angiogenesis. Previous research on cytokines and chemokines, including their downstream targets, has been the focus of the cancer/inflammation connection. The identification of the biological mechanisms of other proteins vital to the inflammation cascade and their interactions are crucial to novel and effective therapeutic protocols for the treatment of inflammation-induced cancers. The Ancelim HSRP Protocol is just such a therapeutic intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ancelim" title="ancelim">ancelim</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor" title=" tumor"> tumor</a> </p> <a href="https://publications.waset.org/abstracts/37512/ancelim-health-system-restoration-protocol-for-cancer-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37512.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">545</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">3023</span> Physiological Normoxia and Cellular Adhesion of Diffuse Large B-Cell Lymphoma Primary Cells: Real-Time PCR and Immunohistochemistry Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamila%20Du%C5%9B-Szachniewicz">Kamila Duś-Szachniewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Kinga%20M.%20Walaszek"> Kinga M.

The knowledge of the molecular and cellular processes involved in abnormalities in cancer cells adhesion has greatly increased, and it has been focused mainly on cellular adhesion molecules (CAMs) and tumor microenvironment. Unfortunately, most of the data regarding CAMs expression relates to study on cells maintained in standard oxygen condition of 21%, while the emerging evidence suggests that culturing cells in ambient air is far from physiological. In fact, oxygen in human tissues ranges from 1 to 11%. The aim of this study was to compare the effects of physiological lymph node normoxia (5% O2), and hyperoxia (21% O2) on the expression of cellular adhesion molecules of primary diffuse large B-cell lymphoma cells (DLBCL) isolated from 10 lymphoma patients. Quantitative RT-PCR and immunohistochemistry were used to confirm the differential expression of several CAMs, including ICAM, CD83, CD81, CD44, depending on the level of oxygen. Our findings also suggest that DLBCL cells maintained at ambient O2 (21%) exhibit reduced growth rate and migration ability compared to the cells growing in normoxia conditions. Taking into account all the observations, we emphasize the need to identify the optimal human cell culture conditions mimicking the physiological aspects of tumor growth and differentiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesion%20molecules" title="adhesion molecules">adhesion molecules</a>, <a href="https://publications.waset.org/abstracts/search?q=diffuse%20large%20B-cell%20lymphoma" title=" diffuse large B-cell lymphoma"> diffuse large B-cell lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20normoxia" title=" physiological normoxia"> physiological normoxia</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20RT-PCR" title=" quantitative RT-PCR"> quantitative RT-PCR</a> </p> <a href="https://publications.waset.org/abstracts/58050/physiological-normoxia-and-cellular-adhesion-of-diffuse-large-b-cell-lymphoma-primary-cells-real-time-pcr-and-immunohistochemistry-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58050.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">278</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">3022</span> Microfluidic Based High Throughput Screening System for Photodynamic Therapy against Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rina%20Lee">Rina Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Hun%20Oh"> Chung-Hun Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunjin%20Lee"> Eunjin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeongyun%20Kim"> Jeongyun Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Photodynamic therapy (PDT) is a treatment that uses a photosensitizer as a drug to damage and kill cancer cells. After injecting the photosensitizer into the bloodstream, the drug is absorbed by cancer cells selectively. Then the area to be treated is exposed to specific wavelengths of light and the photosensitizer produces a form of oxygen that kills nearby cancer cells. PDT is has an advantage to destroy the tumor with minimized side-effects on normal cells. But, PDT is not a completed method for cancer therapy. Because the mechanism of PDT is quite clear yet and the parameters such as intensity of light and dose of photosensitizer are not optimized for different types of cancers. To optimize these parameters, we suggest a novel microfluidic system to automatically control intensity of light exposure with a personal computer (PC). A polydimethylsiloxane (PDMS) microfluidic chip is composed with (1) a cell culture channels layer where cancer cells were trapped to be tested with various dosed photofrin (1μg/ml used for the test) as the photosensitizer and (2) a color dye layer as a neutral density (ND) filter to reduce intensity of light which exposes the cell culture channels filled with cancer cells. Eight different intensity of light (10%, 20%, …, 100%) are generated through various concentrations of blue dye filling the ND filter. As a light source, a light emitting diode (LED) with 635nm wavelength was placed above the developed PDMS microfluidic chip. The total time for light exposure was 30 minutes and HeLa and PC3 cell lines of cancer cells were tested. The cell viability of cells was evaluated with a Live/Dead assay kit (L-3224, Invitrogen, USA). The stronger intensity of light exposed, the lower viability of the cell was observed, and vice versa. Therefore, this system was demonstrated through investigating the PDT against cancer cell to optimize the parameters as critical light intensity and dose of photosensitizer. Our results suggest that the system can be used for optimizing the combinational parameters of light intensity and photosensitizer dose against diverse cancer cell types. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photodynamic%20therapy" title="photodynamic therapy">photodynamic therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=photofrin" title=" photofrin"> photofrin</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20throughput%20screening" title=" high throughput screening"> high throughput screening</a>, <a href="https://publications.waset.org/abstracts/search?q=hela" title=" hela"> hela</a> </p> <a href="https://publications.waset.org/abstracts/30549/microfluidic-based-high-throughput-screening-system-for-photodynamic-therapy-against-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30549.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">383</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">3021</span> Key Roles of the N-Type Oxide Layer in Hybrid Perovskite Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Pauport%C3%A9">Thierry Pauporté</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wide bandgap n-type oxide layers (TiO2, SnO2, ZnO etc.) play key roles in perovskite solar cells. They act as electron transport layers, and they permit the charge separation. They are also the substrate for the preparation of perovskite in the direct architecture. Therefore, they have a strong influence on the perovskite loading, its crystallinity and they can induce a degradation phenomenon upon annealing. The interface between the oxide and the perovskite is important, and the quality of this heterointerface must be optimized to limit the recombination of charges phenomena and performance losses. One can also play on the oxide and use two oxide contact layers for improving the device stability and durability. These aspects will be developed and illustrated on the basis of recent results obtained at Chimie-ParisTech. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxide" title="oxide">oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20perovskite" title=" hybrid perovskite"> hybrid perovskite</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance" title=" impedance"> impedance</a> </p> <a href="https://publications.waset.org/abstracts/65396/key-roles-of-the-n-type-oxide-layer-in-hybrid-perovskite-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65396.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">315</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">3020</span> Establishment of a Thermostable Newcastle Disease Vaccine Candidate Strain and Its Adaptation to Vero Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Humayun%20Kabir">Humayun Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirul%20Hasan"> Amirul Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Miyaoka"> Yu Miyaoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Makiko%20Yamaguchi"> Makiko Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chisaki%20Kadota"> Chisaki Kadota</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuaki%20Takehara"> Kazuaki Takehara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From field isolates of Newcastle disease virus (NDV) in Japan, one avirulent strain, APMV/northern pintail/Japan/Aomori/2003 (dk-Aomori/03, NDV 261), was selected for its excellent thermostability, and the strain was heat-treated at 56℃ temperatures for 30 min with each passage into Vero cells to maintain thermostability and to adapt Vero cells. After serial 20 passages in Vero cells, it was named NDV Vero20. When growth curves were tested in Vero cells, NDV Vero20 grew well to compare the original NDV261. The HN gene was sequenced, and found motifs that show thermostability. The intracerebral pathogenicity index (ICPI) test score was 0. The thermostability of the virus was confirmed by storing it at different temperatures, including at 37°C. When susceptible chicks were inoculated with NDV Vero20 through eye drops, induced adequate levels of antibody were measured using a serum neutralization test. The results showed that NDV Vero20, a vaccine candidate strain is thermostable, Vero cell adapted, and has immunogenic potential, which would make as an alternative to the traditional embryonated chicken eggs-based vaccine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Newcastle%20disease%20virus" title="Newcastle disease virus">Newcastle disease virus</a>, <a href="https://publications.waset.org/abstracts/search?q=thermostability" title=" thermostability"> thermostability</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine" title=" vaccine"> vaccine</a>, <a href="https://publications.waset.org/abstracts/search?q=Vero%20cell%20adaptability" title=" Vero cell adaptability"> Vero cell adaptability</a> </p> <a href="https://publications.waset.org/abstracts/150315/establishment-of-a-thermostable-newcastle-disease-vaccine-candidate-strain-and-its-adaptation-to-vero-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150315.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">142</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">3019</span> Ovarian Surface Epithelium Receptors during Pregnancy and Estrus Cycle of Rats with Emphasis on Steroids and Gonadotropins Fluctuation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salina%20Yahya%20Saddik">Salina Yahya Saddik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study is designed to demonstrate the Ovarian Surface Epithelial cells (OSE) Estrogen Receptor α (ERα) and Progesterone Receptor (PR) during pregnancy and estrous cycle in rat. Moreover, determination of the levels of plasma progesterone, estradiol, FSH and LH were also made. The levels of plasma progesterone, estradiol, FSH and LH concentrations were determined on days 7 (n=5), 14 (n=5), and 21(n=5) of pregnancy in three groups of rats and during the estrous cycle (n=5) using ELISA kit. Immunohistochemical method for PR and ERα expression was also made on the ovary. During pregnancy, FSH and LH remained low except at term when LH levels began to increase from 16 ng/ml to 47 ng/ml. Progesterone levels significantly exceeded estradiol values in all pregnant rats with a peak value of 202 ng/ml on day 14. Elevated progesterone levels were associated negatively with LH and estradiol levels during pregnancy. The levels of estradiol surged significantly on day 21. Immunohistochemistry of the ovary showed low levels of OSE cells staining positive for ERα expression. ERα positive cells were absent on day 7 and 14 of pregnancy, only day 21 recorded a very low percentage of immunostaining (0.5%) within the nuclei of OSE cells. On the contrary, immunostaining of PR was not observed within the nuclei of OSE cells in all groups of study. In conclusions, these results may suggest that progesterone effect during pregnancy seems to be overriding the positive effect of estrogens on OSE cells. High progesterone levels may have a direct negative effect on gonadotropin production and thereby it might inhibit events leading to both follicular development and OSE proliferation. Understanding the factors affecting OSE proliferation may help elucidating the mechanism(s) of assisted diseases such as ovarian cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ovarian%20surface" title="ovarian surface">ovarian surface</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=gonadotropins" title=" gonadotropins"> gonadotropins</a>, <a href="https://publications.waset.org/abstracts/search?q=steroids" title=" steroids"> steroids</a> </p> <a href="https://publications.waset.org/abstracts/7191/ovarian-surface-epithelium-receptors-during-pregnancy-and-estrus-cycle-of-rats-with-emphasis-on-steroids-and-gonadotropins-fluctuation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7191.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">314</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">3018</span> Effect of a Synthetic Platinum-Based Complex on Autophagy Induction in Leydig TM3 Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ezzati%20Givi%20M.">Ezzati Givi M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoveizi%20E."> Hoveizi E.</a>, <a href="https://publications.waset.org/abstracts/search?q=Nezhad%20Marani%20N."> Nezhad Marani N.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Platinum-based anticancer therapeutics are the most widely used drugs in clinical chemotherapy but have major limitations and various side effects in clinical applications. Gonadotoxicity and sterility is one of the most common complications for cancer survivors, which seem to be drug-specific and dose-related. Therefore, many efforts have been dedicated to discovering a new structure of platinum-based anticancer agents with improved therapeutic index, fewer side effects. In this regard, new Pt(II)-phosphane complexes containing heterocyclic thionate ligands (PCTL) have been synthesized, which show more potent antitumor activities in comparison to cisplatin. Cisplatin, the best leading metal-based antitumor drug in the field, induces testicular toxicity on Leydig and Sertoli cells leading to serious side effects such as azoospermia and infertility. Therefore in the present study, we aimed to investigate the cytotoxicity effect of PCTL on mice TM4 Sertoli cells with particular emphasis on the role of autophagy in comparison to cisplatin. In this study, an MTT assay was performed to evaluate the IC50 of PCTL and to analyze the TM3 Leydig cell's viability. Cells morphology was evaluated via invert microscope and Changing in morphology for nuclei swelling or autophagic vacuoles formation were assessed by DAPI and MDC staining. Testosterone production in the culture medium was measured using an ELISA kit. Finally, the expression of Autophagy-related genes, Atg5, Beclin1 and p62, were analyzed by qPCR. Based on the obtained results by MTT, the IC50 value of PCTL was 50 μM in TM3 cells and cytotoxic effects was in a dose- and time-dependent manner. Cells morphological changes investigated by inverted microscopy, DAPI, and MDC staining which showed the cytotoxic concentrations of PCTL was significantly higher than cisplatin in the treated TM3 Leydig cells. The results of PCR showed a lack of expression of the p62, Atg5 and Beclin1 gene in TM3 cells treated with PCTL in comparison to cisplatin and control groups. It should be noted that the effects of 25 μM PCTL concentration on TM3 cells have been associated with increased testosterone production and secretion, which requires further study to explain the possible causes and involved molecular mechanisms. The results of the study showed that the PCTL had less-lethal effects on TM3 cells in comparison to cisplatin and probably did not induce autophagy in TM3 cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=platinum-based%20anticancer%20agents" title="platinum-based anticancer agents">platinum-based anticancer agents</a>, <a href="https://publications.waset.org/abstracts/search?q=cisplatin" title=" cisplatin"> cisplatin</a>, <a href="https://publications.waset.org/abstracts/search?q=Leydig%20TM3%20cells" title=" Leydig TM3 cells"> Leydig TM3 cells</a>, <a href="https://publications.waset.org/abstracts/search?q=autophagy" title=" autophagy"> autophagy</a> </p> <a href="https://publications.waset.org/abstracts/149103/effect-of-a-synthetic-platinum-based-complex-on-autophagy-induction-in-leydig-tm3-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149103.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">128</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">3017</span> Ultrasound Mechanical Index as a Parameter Affecting of the Ability of Proliferation of Cells </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Hormozi%20Moghaddam">Z.

In this study, modeling of the MI was applied to provide treatment protocol and to understand the effective physical processes on reproducibility of stem cells. The acoustic pressure and MI equations are modeled and solved to estimate optimal MI for 28, 40, 150 kHz and 1 MHz frequencies. Radial and axial acoustic pressure distribution was extracted. To validate the results of the modeling, the acoustic pressure in the water and near field depth was measured by a piston hydrophone. Results of modeling and experiments show that the model is consistent well to experimental results with 0.91 and 0.90 correlation of coefficient (p<0.05) for 1 MHz and 40 kHz. Low intensity ultrasound with 0.40 MI is more effective on the proliferation rate of the spermatogonial stem cells during the seven days of culture, in contrast, high MI has a harmful effect on the spermatogonial stem cells. This model provides proper treatment planning <em>in vitro</em> and <em>in vivo</em> by estimating the cavitation phenomenon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title="ultrasound">ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20index" title=" mechanical index"> mechanical index</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cell" title=" stem cell"> stem cell</a> </p> <a href="https://publications.waset.org/abstracts/63084/ultrasound-mechanical-index-as-a-parameter-affecting-of-the-ability-of-proliferation-of-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63084.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">334</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">3016</span> Comparison of the Effectiveness between Exosomes from Different Origins in Reversing Skin Aging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iannello%20G.">Iannello G.</a>, <a href="https://publications.waset.org/abstracts/search?q=Coppa%20F."> Coppa F.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pennisi%20S."> Pennisi S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuffrida%20G."> Giuffrida G.</a>, <a href="https://publications.waset.org/abstracts/search?q=Lo%20Faro%20R."> Lo Faro R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cartelli%20S."> Cartelli S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferruggia%20G."> Ferruggia G.</a>, <a href="https://publications.waset.org/abstracts/search?q=Brundo%20M.%20V."> Brundo M.

Different methods, including dynamic light scattering, scanning electron microscopy, ELISA, and MTT assay, were employed to evaluate on fibroblasts the in vitro effects of plant-derived nanovesicles and cord blood stem cells‐derived exosomes. We compared the results with those of cells exposed to a technology called AMPLEX PLUS, containing a mixture of 20 different biologically active factors (GF20) and exosomes isolated and purified from bovine colostrum. AMPLEX PLUS was able to significantly enhance the cell proliferation status of cells at both 24 and 48 hours compared to untreated cells (control). The obtained results suggest how AMPLEX PLUS could be potentially effective in treating skin rejuvenation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AMPLEX%20PLUS" title="AMPLEX PLUS">AMPLEX PLUS</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20vitality" title=" cell vitality"> cell vitality</a>, <a href="https://publications.waset.org/abstracts/search?q=colostrum" title=" colostrum"> colostrum</a>, <a href="https://publications.waset.org/abstracts/search?q=nanovesicles" title=" nanovesicles"> nanovesicles</a> </p> <a href="https://publications.waset.org/abstracts/187382/comparison-of-the-effectiveness-between-exosomes-from-different-origins-in-reversing-skin-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187382.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">39</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">3015</span> Photovoltaic Cells Characteristics Measurement Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rekioua%20T.">Rekioua T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Rekioua%20D."> Rekioua D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Aissou%20S."> Aissou S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouhabi%20A."> Ouhabi A.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Power provided by the photovoltaic array varies with solar radiation and temperature, since these parameters influence the electrical characteristic (Ipv-Vpv) of solar cells. In Scientific research, there are different methods to obtain these characteristics. In this paper, we present three methods. A simulation one using Matlab/Simulink. The second one is the standard experimental voltage method and the third one is by using LabVIEW software. This latter is based on an electronic circuit to test PV modules. All details of this electronic schemes are presented and obtained results of the three methods with a comparison and under different meteorological conditions are presented. The proposed method is simple and very efficiency for testing and measurements of electrical characteristic curves of photovoltaic panels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20cells" title="photovoltaic cells">photovoltaic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement%20standards" title=" measurement standards"> measurement standards</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20sensors" title=" temperature sensors"> temperature sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20acquisition" title=" data acquisition"> data acquisition</a> </p> <a href="https://publications.waset.org/abstracts/27936/photovoltaic-cells-characteristics-measurement-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27936.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">461</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">3014</span> HLA-G, a Neglected Immunosuppressive Checkpoint for Breast Cancer Immunotherapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xian-Peng%20Jiang">Xian-Peng Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20C.%20Baucom"> Catherine C.

HLA-G also mediates tumor escape, but the immunosuppressive role is often neglected. These studies have focused on the examination of HLA-G expression in human breast carcinoma and HLA-G immunosuppressive role in NK cytolysis. We examined HLA-G expression in breast cell lines by real time PCR, ELISA and immunofluorescent staining. We treated the breast cancer cell lines with anti-human HLA-G antibody or progesterone. Then, NK cytolysis was measured by using MTT assay. We find that breast carcinoma cell lines increase the expression of HLA-G mRNA and protein, compared to normal cells. Blocking HLA-G of the breast cancer cells by the antibody increases NK cytolysis. Progesterone upregulates HLA-G mRNA and protein of human breast cancer cell lines. The increased HLA-G expression suppresses NK cytolysis. In summary, human breast carcinoma overexpress HLA-G immunosuppressive molecules. Blocking HLA-G protein by antibody improves NK cytolysis. In contrast, upregulation of HLA-G expression by progesterone impairs NK cytolytic function. Thus, HLA-G is a new immunosuppressive checkpoint and potential cancer immunotherapeutic target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HLA-G" title="HLA-G">HLA-G</a>, <a href="https://publications.waset.org/abstracts/search?q=Breast%20carcinoma" title=" Breast carcinoma"> Breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=NK%20cells" title=" NK cells"> NK cells</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunosuppressive%20checkpoint" title=" Immunosuppressive checkpoint"> Immunosuppressive checkpoint</a> </p> <a href="https://publications.waset.org/abstracts/161283/hla-g-a-neglected-immunosuppressive-checkpoint-for-breast-cancer-immunotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161283.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">88</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">3013</span> Characterization of Retinal Pigmented Cell Epithelium Cell Sheet Cultivated on Synthetic Scaffold</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tan%20Yong%20Sheng%20Edgar">Tan Yong Sheng Edgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeong%20Wai%20Yee"> Yeong Wai Yee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Age-related macular degeneration (AMD) is one of the leading cause of blindness. It can cause severe visual loss due to damaged retinal pigment epithelium (RPE). RPE is an important component of the retinal tissue. It functions as a transducing boundary for visual perception making it an essential factor for sight. The RPE also functions as a metabolically complex and functional cell layer that is responsible for the local homeostasis and maintenance of the extra photoreceptor environment. Thus one of the suggested method of treating such diseases would be regenerating these RPE cells. As such, we intend to grow these cells using a synthetic scaffold to provide a stable environment that reduces the batch effects found in natural scaffolds. Stiffness of the scaffold will also be investigated to determine the optimal Young’s modulus for cultivating these cells. The cells will be generated into a monolayer cell sheet and their functions such as formation of tight junctions and gene expression patterns will be assessed to evaluate the cell sheet quality compared to a native RPE tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RPE" title="RPE">RPE</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title=" scaffold"> scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title=" biomaterials"> biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=colloids%20and%20nanomedicine" title=" colloids and nanomedicine"> colloids and nanomedicine</a> </p> <a href="https://publications.waset.org/abstracts/13922/characterization-of-retinal-pigmented-cell-epithelium-cell-sheet-cultivated-on-synthetic-scaffold" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13922.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">435</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">3012</span> The Effect of Manggong Bamboo Leaves Extract (Gigantochloa manggong) on Rat (Rattus novergicus) Blood Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Rahayu">Sri Rahayu</a>, <a href="https://publications.waset.org/abstracts/search?q=Supriyatin"> Supriyatin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuli%20Rahma%20Dini"> Yuli Rahma Dini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the consequences of excess physical activity is the oxidative stress which resulted in damage to blood cells. Oxidative stress condition can be reduced by an exogenous antioxidant. The natural exogenous antioxidant can be extracted from Manggong bamboo (Gigantochloa manggong). This research was aim to evaluate the effect of physical exercise and Manggong bamboo (Gigantochloa manggong) leaf extract on blood profile of rats. This research was conducted in July 2013 to May 2014 using experimental method with completely randomized design (CRD) with two factors, physical exercise and Manggong bamboo leaf extract. The rats blood profile to be measured were the level of erythrocyte cells, leucocyte cells and hemoglobin. Data were analyzed with parametric statistical 2-way ANOVA test (α = 0.05). Manggong bamboo leaf extract was non toxic and contained flavonoid, triterpenoid, saponin and alkaloid. There was an effect of physical exercise and manggong bamboo leaf extract on blood profile of rats. Data obtained on physical activity, giving erythrocyte cells (2.5 million/µl) and hemoglobin (12,42g/dL) declined compared to the number of leucocyte cells increases (6,500cells/L). Extract treatment was increased the erythrocytes (5,13 million/µl) and hemoglobin level (14,72 g/dL.) while the leukocytes level were decreased (1.591,67 cells/L). The extract and physical activity treatment showed an increase in erythrocytes (2,96 million/µl) and hemoglobin (14,3 g/dL) but decrease the number of leukocytes (1.291,67 cells/L).

This study aimed at prospectively collecting information on the clinical profile of Plasmodium vivax from subjects acutely infected with P. vivax residing in some of the highest malaria transmission regions in Thailand. Methods: A retrospective study of malaria cases, hospitalized between 2013 and 2015 was performed. Clinical characteristics, diagnosis, and parasitological results on admission, age, and gender were mined from medical records at Phop Phra Hospital located in endemic areas of Tak Province, Thailand. Venous blood samples were collected at the time of admission to the hospital to determine the present of parasite and also parasite count by thick and thin film examination, and also Complete blood count (CBC) parameters. Results: Results showed that patients infected with Plasmodium vivax (276 cases) had a high monocyte count (mean=390 cells/µL) during initial stage of infection and continuously lower during later stage (any stage with gametocyte, mean=230 cells/µL) of infection (P value=0.021) whereas, patients infected with Plasmodium vivax had a low basophil count (mean=20 cells/µL) during initial stage of infection and continuously higher during later stage of infection (mean at stage with gametocyte=70 cells/µL) (P value=0.033). In addition, patients with more than one stage infection tend to have lower lymphocyte count (mean=1180 cells/µL) than patients with only one stage infection (mean=1350 cells/µL)(P value=0.011) whereas, patients with more than one stage infection tend to have lower basophil count (mean=60 cells/µL) than patients with only one stage infection (mean=80 cells/µL) (P value=0.01). Conclusion: This study indicated that patients infected with Plasmodium vivax had high monocyte count and low basophil count during initial stage of infection which was continuously lower during later stage of infection. Patients with more than one stage infection tend to have lower lymphocyte count than patients with only one stage infection whereas, patients with more than one stage infection tend to have lower basophil count than patients with only one stage infection. This information contributes to better understanding of pathological characteristic of Plasmodium vivax infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasmodium%20vivax" title="plasmodium vivax">plasmodium vivax</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a>, <a href="https://publications.waset.org/abstracts/search?q=asexual%20erythrocytic%20stages" title=" asexual erythrocytic stages"> asexual erythrocytic stages</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20parameters" title=" hematological parameters "> hematological parameters </a> </p> <a href="https://publications.waset.org/abstracts/56781/the-abnormality-of-blood-cells-parasitized-by-plasmodium-vivax" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56781.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">212</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">3010</span> Supergranulation and Its Turbulent Convection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Paniveni">U.

The turbulent aspect of the solar supergranulation is established by examining the interrelationships amongst the parameters characterizing a supergranular cell, namely size, lifetime, area, perimeter, fractal dimension, and horizontal flow velocity. The complexity of supergranular cells depicted by their fractal dimension is indicative of their non-laminar characteristics. The findings corroborate Kolmogorov’s theory of turbulence. Some parameters of supergranular cells also show a latitudinal dependence. Supergranulation is a synonym of convective phenomenon and hence can shed light on the physical conditions in the convection zone of the Sun. It plays a major role in the transport and dispersal of magnetic fields that may have a relation to the phases of the solar cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sun" title="sun">sun</a>, <a href="https://publications.waset.org/abstracts/search?q=granulation" title=" granulation"> granulation</a>, <a href="https://publications.waset.org/abstracts/search?q=convection" title=" convection"> convection</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence" title=" turbulence"> turbulence</a> </p> <a href="https://publications.waset.org/abstracts/187329/supergranulation-and-its-turbulent-convection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187329.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">40</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">3009</span> Calpain-Mediated, Cisplain-Induced Apoptosis in Breast Cancer Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shadia%20Al-Bahlani">Shadia Al-Bahlani</a>, <a href="https://publications.waset.org/abstracts/search?q=Khadija%20Al-Bulushi"> Khadija Al-Bulushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuweina%20Al-Hadidi"> Zuweina Al-Hadidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Buthaina%20Al-Dhahl"> Buthaina Al-Dhahl</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Al-Abri"> Nadia Al-Abri </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer is the most common cancer in women worldwide. Triple-Negative Breast Cancer (TNBC) is an aggressive type of breast cancer, which is defined by the absence of Estrogen (ER), Progesterone (PR) and human epidermal growth factor (Her-2) receptors. The calpain system plays an important role in many cellular processes including apoptosis, necrosis, cell signaling and proliferation. However, the role of calpain in cisplatin (CDDP)-induced apoptosis in TNBC cells is not fully understood. Here, TNBC (MDA-MB231) cells were treated with different concentration of CDDP (0, 20 & 40 µM) and calpain activation and apoptosis were measured by western blot and Hoechst Stain respectively. In addition, calpain modulation by either activation and/or inhibition and its effect on CDDP-induced apoptosis were assessed by the same above approaches. Our findings showed that CDDP induced endoplasmic reticulum stress and thus Calcium release and subsequently activate calpain α-fodrin cleavage indicated by the increase in GRP78 and Calmodulin protein expression and respectively in MDA-MB231 cells. It also induced apoptosis as measured by Hoechst stain and caspase-12 cleavage. Calpain activation by both Cyclopiazonic acid and Thapsigargin showed similar effect and enhanced the sensitivity of these cells to CDDP treatment. On the other hand, calpain inhibition by either specific siRNA and/or exogenous inhibitor (Calpeptin) had an adverse effect where it attenuated calpain activation and thus CDDP- induced apoptosis in these cells. Altogether, these findings suggested that calpain activation play an essential role in sensitizing the TNBC cells to CDDP-induced apoptosis. This might lead to the discovery of novel treatment to over this aggressive type of breast cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calpain" title="calpain">calpain</a>, <a href="https://publications.waset.org/abstracts/search?q=cisplatin" title=" cisplatin"> cisplatin</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a> </p> <a href="https://publications.waset.org/abstracts/30464/calpain-mediated-cisplain-induced-apoptosis-in-breast-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30464.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">3008</span> Microdosimetry in Biological Cells: A Monte Carlo Method </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Jabal%20Ameli">Hamidreza Jabal Ameli</a>, <a href="https://publications.waset.org/abstracts/search?q=Anahita%20Movahedi"> Anahita Movahedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: In radionuclide therapy, radioactive atoms are coupled to monoclonal antibodies (mAbs) for treating cancer tumor while limiting radiation to healthy tissues. We know that tumoral and normal tissues are not equally sensitive to radiation. In fact, biological effects such as cellular repair processes or the presence of less radiosensitive cells such as hypoxic cells should be taken account. For this reason, in this paper, we want to calculate biological effect dose (BED) inside tumoral area and healthy cells around tumors. Methods: In this study, deposited doses of a radionuclide, gold-198, inside cells lattice and surrounding healthy tissues were calculated with Monte Carlo method. The elemental compositions and density of malignant and healthy tissues were obtained from ICRU Report 44. For reaching to real condition of oxygen effects, the necrosis and hypoxia area inside tumors has been assessed. Results: With regard to linear-quadratic expression which was defined in Monte Carlo, results showed that a large amount of BED is deposited in the well-oxygenated part of the hypoxia area compared to necrosis area.

We, therefore, concluded that effect of Grayanotoxins on contraction and membrane potential of C2C12 relate to acute toxicity of GTXs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=skeletal%20muscle%20cells%20C2C12" title="skeletal muscle cells C2C12">skeletal muscle cells C2C12</a>, <a href="https://publications.waset.org/abstracts/search?q=grayanotoxins" title=" grayanotoxins"> grayanotoxins</a>, <a href="https://publications.waset.org/abstracts/search?q=contraction" title=" contraction"> contraction</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20potential" title=" membrane potential"> membrane potential</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20toxicity" title=" acute toxicity"> acute toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=pytotoxin" title=" pytotoxin"> pytotoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=motubes" title=" motubes "> motubes </a> </p> <a href="https://publications.waset.org/abstracts/23536/contraction-and-membrane-potential-of-c2c12-with-gtxs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23536.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">505</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">3006</span> Fabrication and Properties of Al2O3/Si Quantum Well-Structured Silicon Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwang-Ho%20Kim">Kwang-Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwan-Hong%20Min"> Kwan-Hong Min</a>, <a href="https://publications.waset.org/abstracts/search?q=Pyungwoo%20Jang"> Pyungwoo Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chisup%20Jung"> Chisup Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyu%20Seomoon"> Kyu Seomoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By restricting the dimensions of silicon to less than Bohr radius of bulk crystalline silicon (∼5 nm), quantum confinement causes its effective bandgap to increase. Therefore, silicon quantum wells (QWs) using these quantum phenomena could be a good candidate to achieve high performance silicon solar cells. The Al2O3/Si QW structures were fabricated by using the successive deposition technique, as a quantum confinement device to increase the effective energy bandgap and passivation effect in Si surface for the 3rd generation solar cell applications. In Si/Al2O3 QWs, the thicknesses of Si layers and Al2O3 layers were varied between 1 to 5 nm, respectively. The roughness of deposited Si on Al2O3 was less than 4 Å in the thickness of 2 nm. By using the Al2O3/Si QW structures on Si surfaces, the lifetime measured by u-PCD technique increased as a result of passivated surface effects. The discussion about the other properties such as electrical and optical properties of the QWs structures as well as the fabricated solar cells will be presented in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al2O3%2FSi%20quantum%20well" title="Al2O3/Si quantum well">Al2O3/Si quantum well</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20confinement" title=" quantum confinement"> quantum confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=third%20generation" title=" third generation"> third generation</a>, <a href="https://publications.waset.org/abstracts/search?q=successive%20deposition%20technique" title=" successive deposition technique"> successive deposition technique</a> </p> <a href="https://publications.waset.org/abstracts/6308/fabrication-and-properties-of-al2o3si-quantum-well-structured-silicon-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6308.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">340</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">3005</span> Spectral Response Measurements and Materials Analysis of Ageing Solar Photovoltaic Modules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20H.%20Huang">T.

In this study, the accelerated aging of different light sources was combined with spectral response measurements to understand the effect of light sources on aging tests. In this study, there are two types of experimental samples: packaged and unpackaged and then irradiated with full-spectrum and UVC light sources for accelerated aging, as well as a control group without aging. The full-spectrum aging was performed by irradiating the solar cell with a xenon lamp like the solar spectrum for two weeks, while the accelerated aging was performed by irradiating the solar cell with a UVC lamp for two weeks. The samples were first visually observed, and infrared thermal images were taken, and then the electrical (IV) and Spectral Responsivity (SR) data were obtained by measuring the spectral response of the samples, followed by Scanning Electron Microscopy (SEM), Raman spectroscopy (Raman), and X-ray Diffraction (XRD) analysis. The results of electrical (IV) and Spectral Responsivity (SR) and material analyses were used to compare the differences between packaged and unpackaged solar cells with full spectral aging, accelerated UVC aging, and unaged solar cells. The main objective of this study is to compare the difference in the aging of packaged and unpackaged solar cells by irradiating different light sources. We determined by infrared thermal imaging that both full-spectrum aging and UVC accelerated aging increase the defects of solar cells, and IV measurements demonstrated that the conversion efficiency of solar cells decreases after full-spectrum aging and UVC accelerated aging. SEM observed some scorch marks on both unpackaged UVC accelerated aging solar cells and unpackaged full-spectrum aging solar cells. Raman spectroscopy examines the Si intensity of solar cells, and XRD confirms the crystallinity of solar cells by the intensity of Si and Ag winding peaks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title="solar cell">solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=aging" title=" aging"> aging</a>, <a href="https://publications.waset.org/abstracts/search?q=spectral%20response%20measurement" title=" spectral response measurement"> spectral response measurement</a> </p> <a href="https://publications.waset.org/abstracts/150077/spectral-response-measurements-and-materials-analysis-of-ageing-solar-photovoltaic-modules" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150077.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">101</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">3004</span> Global Stability Analysis of a Coupled Model for Healthy and Cancerous Cells Dynamics in Acute Myeloid Leukemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhafid%20Zenati">Abdelhafid Zenati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Tadjine"> Mohamed Tadjine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mathematical formulation of biomedical problems is an important phase to understand and predict the dynamic of the controlled population.

This study is to determine the effect of H2S on TLR4 mediated innate immune signaling in acute pancreatitis via substance P (SP). Male Swiss mice were treated with hourly intraperitoneal injection of caerulein (50μg/kg) for 10 hour. DL-propargylglycine (PAG) (100 mg/kg i.p.), an inhibitor of H2S formation was administered 1h after the induction of acute pancreatitis. Pancreatic acinar cells from male Swiss mice were incubated with or without caerulein (10–7 M for 60 min) and CP-96345 (NK1R inhibitor). To better understand the effect of H2S in inflammation, acinar cells were stimulated with caerulein after addition of H2S donor, NaHS. In addition, caerulein treated pancreatic acinar cells were pretreated with PAG (30 µM), for 1h. H2S inhibitor, PAG, eliminated TLR4, IRAK4, TRAF6 and NF-kB levels in an in vitro and in vivo model of caerulein-induced acute pancreatitis. PPTA gene deletion reduced TLR4, MyD88, IRAK4, TRAF6, adhesion molecules and NF-kB in caerulein treated pancreatic acinar cells whereas administration of NaHS resulted in further rise in TLR4 and NF-kB levels in caerulein treated pancreatic acinar cells. In addition, acini isolated from mice and treated with PPTA gene receptor NK1R antagonist CP96345 did not exhibit further increase in TLR4, IRAK4, TRAF6, adhesion molecules and NF-kB levels after NaHS pretreatment. The present findings show for the first time that in acute pancreatitis, H2S up-regulates TLR4 pathway and NF-kB via substance P. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=preprotachykinin-A%20gene" title="preprotachykinin-A gene">preprotachykinin-A gene</a>, <a href="https://publications.waset.org/abstracts/search?q=H2S" title=" H2S"> H2S</a>, <a href="https://publications.waset.org/abstracts/search?q=TLR4" title=" TLR4"> TLR4</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20pancreatitis" title=" acute pancreatitis"> acute pancreatitis</a> </p> <a href="https://publications.waset.org/abstracts/28761/cp-96345-rregulates-hydrogen-sulphide-induced-tlr4-signaling-pathway-adhesion-molecules-in-caerulein-treated-pancreatic-acinar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28761.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">276</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">3002</span> An Investigation of Anticancer Fluorinated Aza-Heterocycles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darya%20O.%20Prima">Darya O.

The diazoles, triazoles and selenadiazoles revealed low medium inhibitory concentrations IC50 = 2.2-26.4 µМ and induced the cells’ apoptosis at low concentrations C = 1-25 µМ. For selenadiazoles, cell death dynamics was observed already in the first hours after the treatment. Replacement of one atom F by group Me2N in some cases enlarged apoptotic activity of the compounds towards the Hep2 cells. In contrast, the archetypal (i.e. non-fluorinated) 1,3-benzodiazole, 1,2,3-benzotriazole and 2,1,3-benzoselenadiazole were low toxic (IC50 > 100 µM) and induced apoptosis only at high concentrations. The chlorinated congeners of the heterocycles under discussion were highly toxic towards the Hep2 cells but revealed insignificant ability to induce their apoptosis. Overall, the findings above suggest that fluorinated 1,3-benzodiazole, 1,2,3-benzotriazole and 2,1,3-benzoselenadiazole derivatives can be considered as potential anticancer drugs. For the laryngeal epidermoid carcinoma (for which, according to available statistics, the five-year survival rate remained ~50% during the past 30 years), it is especially important since surgical treatment is seriously complicated here thus encouraging medicament one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apoptosis"
