of the immune system. The urinary tract and urethra of these children can be easily infected areas because of glycosuria. Aim: The microflora assessment of the urethra area of children with newly diagnosed T1D. Methods: The materials of the study were swabs taken prospectively from the urethral area of 63 children at the time of diagnosis of T1D (37 boys), then the results were correlated to the clinical parameters. In the statistical analysis, there were T student, Chi square, and U Mann-Whitney tests used. Results: The mean age was 9.4 years (6 months-17.4 years). The mean HbA1c value was 12.1% (5,6% - 20.1%). The mean value of glycosuria was 4463.2 mg/dl (0 - 9770 mg/dl). Ketoacidosis was diagnosed in 29 children (49%). The following microbial species were isolated in the collected materials: Staphylococcus epidermidis in 18 children (28.6%), Enterococcus faecalis in 17 children (27%), Candida albicans in 15 children (23.8%), coagulase-negative staphylococciin 11 children (17.5%), group B Streptococcus beta-hemolysis in 10 children (15.9%), S. aureus, E. coli, S. anginosus, C. glucuronolyticum, and A. urinae in 7 children each (11.1%), group B Streptococcus beta-hemolysis and S. hominis in 6 children each (9.5%), L. gasseri in 5 children (7.5%), C. dubliniensis in 4 children (6.3) and other, isolated cases. 2 of diagnosed patients were cultured negatively (3.2%). There were statistical correlations between the type of colonisation and patients’ sex and HbA1C value. Conclusions: It is extremely important to examine the urethral area at the time of diagnosis of T1D in order to detect inflammation and to undertake the appropriate and effective intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetology" title="diabetology">diabetology</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20disorders" title=" skin disorders"> skin disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiology" title=" microbiology"> microbiology</a>, <a href="https://publications.waset.org/abstracts/search?q=microflora" title=" microflora"> microflora</a> </p> <a href="https://publications.waset.org/abstracts/147101/the-microflora-assessment-of-the-urethra-area-of-children-with-newly-diagnosed-type-1-diabetes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147101.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">327</span> Host Responses in Peri-Implant Tissue in Comparison to Periodontal Tissue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raviporn%20Madarasmi">Raviporn Madarasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Anjalee%20Vacharaksa"> Anjalee Vacharaksa</a>, <a href="https://publications.waset.org/abstracts/search?q=Pravej%20Serichetaphongse"> Pravej Serichetaphongse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The host response in peri-implant tissue may differ from that in periodontal tissue in a healthy individual. The purpose of this study is to investigate the expression of inflammatory cytokines in peri-implant crevicular fluid (PICF) from single implant with different abutment types in comparison to healthy periodontal tissue. 19 participants with healthy implants and teeth were recruited according to inclusion and exclusion criteria. PICF and gingival crevicular fluid (GCF) was collected using sterile paper points. The expression level of inflammatory cytokines including IL-1α, IL-1β, TNF-α, IFN-γ, IL-6, and IL-8 was assessed using enzyme-linked immunosorbent assay (ELISA). Paired t test was used to compare the expression levels of inflammatory cytokines around natural teeth and peri-implant in PICF and GCF of the same individual. The Independent t-test was used to compare the expression levels of inflammatory cytokines in PICF from titanium and UCLA abutment. Expression of IL-6, TNF-α, and IFN-γ in PICF was not statistically different from GCF among titanium and UCLA abutment group. However, the level of IL-1α in the PICF from the implants with UCLA abutment was significantly higher than GCF (P=0.030). In addition, the level of IL-1β in PICF from the implants with titanium abutment was significantly higher than GCF (P=0.032). When different abutment types was compared, IL-8 expression in PICF from implants with UCLA abutment was significantly higher than titanium abutment (P=0.003). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abutment" title="abutment">abutment</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20implant" title=" dental implant"> dental implant</a>, <a href="https://publications.waset.org/abstracts/search?q=gingival%20crevicular%20fluid%20and%20peri-implant%20crevicular%20fluid" title=" gingival crevicular fluid and peri-implant crevicular fluid"> gingival crevicular fluid and peri-implant crevicular fluid</a> </p> <a href="https://publications.waset.org/abstracts/75686/host-responses-in-peri-implant-tissue-in-comparison-to-periodontal-tissue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75686.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">185</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">326</span> Ethnobotanical Study, Phytochemical Screening, and Biological Activity of Culinary Spices Commonly Used in Ommdurman, Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Randa%20M.%20T.%20Mohamed">Randa M.

Besides, spices are equally used for therapeutic purposes. The objective of this study was to survey and document the medicinal properties of spices commonly used in the Sudanese kitchen for different food preparations. Also, extracts from reported spices were screened for the presence of secondary metabolites as well as their antioxidant and beta-lactamase inhibitory properties. This study was conducted in the Rekabbya Quartier in Omdurman, Khartoum State, Sudan. Information was collected by carrying out semi-structured interviews. All informants (30) in the present study were women. Spices were purchased from Attareen shop in Omdurman. Essential oils from spices were extracted by hydrodistillation, and ethanolic extracts by maceration. Phytochemical screening was performed by thin-layer chromatography (TLC). The antioxidant capacity of essential oils and ethanolic extracts was investigated through TLC bioautography. Beta lactamase inhibitory activity was performed by the acidimetric test. Ethnobotany study showed that a total of 16 spices were found to treat 36 ailments belonging to 10 categories. The most frequently claimed medicinal uses were for the digestive system diseases treated by 14 spices and respiratory system diseases treated by 8 spices. Gynecological problems were treated with 4 spices. Dermatological diseases were cured by 5 spices, while infections caused by tapeworms and other microbes causing dysentery were treated by 3 spices. 4 spices were used to treat bad breath, bleeding gum and toothache. Headache, eyes infection, cardiac stimulation and epilepsy were treated with one spice each. Other health problems like fatigue and loss of appetite, and low breast milk production were treated by 1, 3 and 2 spices, respectively. The majority (69%, 11/16) of spices were exported from different countries like India, China, Indonesia, Ethiopia, Egypt and Nigeria, while 31% (5/16) was cultivated in Sudan. Essential oils of all spices were rich in terpenes, while ethanolic extracts contained variable classes of secondary metabolites. Both essential oils and ethanolic extracts of all spices exerted considerable antioxidant activity. Only one extract, Syzygium aromaticum, possessed beta-lactamase inhibitory activity. In conclusion, this study could contribute to conserving information on traditional medicinal uses of spices in Sudan. Also, the results demonstrated the potential of some of these spices to exert beneficial antimicrobial and antioxidant effects. Detailed phytochemical and biological assays of these spices are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spices" title="spices">spices</a>, <a href="https://publications.waset.org/abstracts/search?q=enthnobotany" title=" enthnobotany"> enthnobotany</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=betalactamase%20inhibition" title=" betalactamase inhibition"> betalactamase inhibition</a> </p> <a href="https://publications.waset.org/abstracts/189634/ethnobotanical-study-phytochemical-screening-and-biological-activity-of-culinary-spices-commonly-used-in-ommdurman-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189634.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">32</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">325</span> Role of Inflammatory Markers in Arthritic Rats Treated with Ethanolic Bark Extract of Albizia procera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sangeetha">M.

Despite improvements in the treatment of RA over the past decade, there still is a need for new therapeutic agents that are efficacious, less expensive, and free of severe adverse reactions. The present study aimed to investigate role of inflammatory markers in arthritic rats treated with ethanolic bark extract of <i>Albizia procera</i>. The protective effect of ethanolic bark extract of <i>Albizia procera </i>against complete Freund’s adjuvant (CFA) induced arthritis in rats. Arthritis was induced by an intradermal injection of 0.1 ml FCA in the foot pad of left hind limb of rats. ETBE (100 and 200 mg/kg b.wt./p.o) and the reference drug diclofenac (25 mg/kg b.wt./p.o) were administered to arthritic rats. Paw volume was measured for all the animals before inducing arthritis and thereafter once in seven days by using plethysmometer for 42 days. Gene expression of inflammatory markers such as IL-1β and IL-10 were investigated in paw tissues. Up regulation of IL-1β and Down regulation IL-10 were observed in CFA injected rats when compared to normal rats. ETBE attenuated these alterations dose dependently when compared to the vehicle treated rats. These results provide insights into the mechanism of anti-arthritic activity, and unravel potential therapeutic use of <i>Albizia procera </i>in arthritis.<o:p> </o:p></span> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFA-Complete%20Freund%E2%80%99s%20adjuvant" title="CFA-Complete Freund’s adjuvant">CFA-Complete Freund’s adjuvant</a>, <a href="https://publications.waset.org/abstracts/search?q=ETBE%20%E2%80%93%20ethanolic%20bark%20extract" title=" ETBE – ethanolic bark extract"> ETBE – ethanolic bark extract</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-%20interleukins" title=" IL- interleukins"> IL- interleukins</a>, <a href="https://publications.waset.org/abstracts/search?q=RA-rheumatoid%20arthritis" title=" RA-rheumatoid arthritis"> RA-rheumatoid arthritis</a> </p> <a href="https://publications.waset.org/abstracts/52352/role-of-inflammatory-markers-in-arthritic-rats-treated-with-ethanolic-bark-extract-of-albizia-procera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52352.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">285</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">324</span> Flow Links Curiosity and Creativity: The Mediating Role of Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20S.%20Schutte">Nicola S.

Malouff</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Curiosity is a positive emotion and motivational state that consists of the desire to know. Curiosity consists of several related dimensions, including a desire for exploration, deprivation sensitivity, and stress tolerance. Creativity involves generating novel and valuable ideas or products. How curiosity may prompt greater creativity remains to be investigated. The phenomena of flow may link curiosity and creativity. Flow is characterized by intense concentration and absorption and gives rise to optimal performance. Objective of Study: The objective of the present study was to investigate whether the phenomenon of flow may link curiosity with creativity. Methods and Design: Fifty-seven individuals from Australia (45 women and 12 men, mean age of 35.33, SD=9.4) participated. Participants were asked to design a program encouraging residents in a local community to conserve water and to record the elements of their program in writing. Participants were then asked to rate their experience as they developed and wrote about their program. Participants rated their experience on the Dimensional Curiosity Measure sub-scales assessing the exploration, deprivation sensitivity, and stress tolerance facets of curiosity, and the Flow Short Scale. Reliability of the measures as assessed by Cronbach's alpha was as follows: Exploration Curiosity =.92, Deprivation Sensitivity Curiosity =.66, Stress Tolerance Curiosity =.93, and Flow=.96. Two raters independently coded each participant’s water conservation program description on creativity. The mixed-model intraclass correlation coefficient for the two sets of ratings was .73. The mean of the two ratings produced the final creativity score for each participant. Results: During the experience of designing the program, all three types of curiosity were significantly associated with the flow. Pearson r correlations were as follows: Exploration Curiosity and flow, r =.68 (higher Exploration Curiosity was associated with more flow); Deprivation Sensitivity Curiosity and flow, r =.39 (higher Deprivation Sensitivity Curiosity was associated with more flow); and Stress Tolerance Curiosity and flow, r = .44 (more stress tolerance in relation to novelty and exploration was associated with more flow). Greater experience of flow was significantly associated with greater creativity in designing the water conservation program, r =.39. The associations between dimensions of curiosity and creativity did not reach significance. Even though the direct relationships between dimensions of curiosity and creativity were not significant, indirect relationships through the mediating effect of the experience of flow between dimensions of curiosity and creativity were significant. Mediation analysis using PROCESS showed that flow linked Exploration Curiosity with creativity, standardized beta=.23, 95%CI [.02,.25] for the indirect effect; Deprivation Sensitivity Curiosity with creativity, standardized beta=.14, 95%CI [.04,.29] for the indirect effect; and Stress Tolerance Curiosity with creativity, standardized beta=.13, 95%CI [.02,.27] for the indirect effect. Conclusions: When engaging in an activity, higher levels of curiosity are associated with greater flow. More flow is associated with higher levels of creativity. Programs intended to increase flow or creativity might build on these findings and also explore causal relationships. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=curiosity" title=" curiosity"> curiosity</a>, <a href="https://publications.waset.org/abstracts/search?q=flow" title=" flow"> flow</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a> </p> <a href="https://publications.waset.org/abstracts/107377/flow-links-curiosity-and-creativity-the-mediating-role-of-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107377.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">184</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">323</span> The Effect of Dendrobium nobile Lindl.

Dendrobium nobile Lindl. Alkaloids (DNLA) as one of the active compounds of Dendrobium nobile Lindl. In this study, we attempted to verify the hypoglycemic effect and investigate the effects of DNLA on the amyloid precursor protein (APP) metabolic pathway of the hippocampus in db/db mice. Methods: 4-weeks-old male C57BL/KsJ mice were the control group. And the same age and sexuality db/db mice were: model, DNLA-L (20 mg/kg), DNLA-M (40 mg/kg), and DNLA-H (80 mg/kg). After, mice were treated with different concentrations of DNLA for 17 weeks. The fasting blood glucose (FBG) was detected by glucose oxidase assay every week from the 4th to last week. The protein expression of β-amyloid 1-42 (Aβ1-42), β-site amyloid precursor protein-cleaving enzyme 1 (BACE1), and APP were examined by Western blotting. Results: The concentration of FBG and the protein expression of Aβ1-42, BACE1, and APP were increased in the hippocampus of the model group. Moreover, DNLA not only significantly decreased the concentration of FBG but also reduced the protein expressions of Aβ1-42, BACE1 and APP in the hippocampus of db/db mice in a dose-dependent manner. Conclusions: DNLA can decrease the protein expressions of Aβ1-42 in the hippocampus of db/db mice, and the mechanism may be involved in the APP metabolic pathway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%27s%20disease" title="Alzheimer's disease">Alzheimer's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20diabetes%20mellitus" title=" type 2 diabetes mellitus"> type 2 diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B2-site%20amyloid%20precursor%20protein-cleaving%20enzyme%201" title=" β-site amyloid precursor protein-cleaving enzyme 1"> β-site amyloid precursor protein-cleaving enzyme 1</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20Chinese%20medicines" title=" traditional Chinese medicines"> traditional Chinese medicines</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-amyloid" title=" beta-amyloid"> beta-amyloid</a> </p> <a href="https://publications.waset.org/abstracts/152548/the-effect-of-dendrobium-nobile-lindl-alkaloids-on-the-blood-glucose-and-amyloid-precursor-protein-metabolic-pathways-in-dbdb-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152548.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">257</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">322</span> Weakly Solving Kalah Game Using Artificial Intelligence and Game Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiba%20El%20Assibi">Hiba El Assibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to weakly solve Kalah, a two-player board game, by developing a start-to-finish winning strategy using an optimized Minimax algorithm with Alpha-Beta Pruning. In weakly solving Kalah, our focus is on creating an optimal strategy from the game's beginning rather than analyzing every possible position. The project will explore additional enhancements like symmetry checking and code optimizations to speed up the decision-making process. This approach is expected to give insights into efficient strategy formulation in board games and potentially help create games with a fair distribution of outcomes. Furthermore, this research provides a unique perspective on human versus Artificial Intelligence decision-making in strategic games. By comparing the AI-generated optimal moves with human choices, we can explore how seemingly advantageous moves can, in the long run, be harmful, thereby offering a deeper understanding of strategic thinking and foresight in games. Moreover, this paper discusses the evaluation of our strategy against existing methods, providing insights on performance and computational efficiency. We also discuss the scalability of our approach to the game, considering different board sizes (number of pits and stones) and rules (different variations) and studying how that affects performance and complexity. The findings have potential implications for the development of AI applications in strategic game planning, enhancing our understanding of human cognitive processes in game settings, and offer insights into creating balanced and engaging game experiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minimax" title="minimax">minimax</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha%20beta%20pruning" title=" alpha beta pruning"> alpha beta pruning</a>, <a href="https://publications.waset.org/abstracts/search?q=transposition%20tables" title=" transposition tables"> transposition tables</a>, <a href="https://publications.waset.org/abstracts/search?q=weakly%20solving" title=" weakly solving"> weakly solving</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a> </p> <a href="https://publications.waset.org/abstracts/183486/weakly-solving-kalah-game-using-artificial-intelligence-and-game-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183486.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">55</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">321</span> Evaluation of Gene Expression after in Vitro Differentiation of Human Bone Marrow-Derived Stem Cells to Insulin-Producing Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20Zakaria">Mahmoud M.

Our aim is to evaluate relative gene expression for each independent protocol. Human bone marrow cells were derived from three volunteers that suffer diabetes disease. After expansion of mesenchymal stem cells, differentiation of these cells was done by three different protocols (the one-step protocol was used conophylline protein, the two steps protocol was depending on trichostatin-A, and the three-step protocol was started by beta-mercaptoethanol). Evaluation of gene expression was carried out by real-time PCR: Pancreatic endocrine genes, transcription factors, glucose transporter, precursor markers, pancreatic enzymes, proteolytic cleavage, extracellular matrix and cell surface protein. Quantitation of insulin secretion was detected by immunofluorescence technique in 24-well plate. Most of the genes studied were up-regulated in the in vitro differentiated cells, and also insulin production was observed in the three independent protocols. There were some slight increases in expression of endocrine mRNA of two-step protocol and its insulin production. So, the two-step protocol was showed a more efficient in expressing of pancreatic endocrine genes and its insulin production than the other two protocols. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</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=conophylline%20protein" title=" conophylline protein"> conophylline protein</a>, <a href="https://publications.waset.org/abstracts/search?q=trichostatin-A" title=" trichostatin-A"> trichostatin-A</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-mercaptoethanol" title=" beta-mercaptoethanol"> beta-mercaptoethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=immunofluorescence%20technique" title=" immunofluorescence technique"> immunofluorescence technique</a> </p> <a href="https://publications.waset.org/abstracts/85954/evaluation-of-gene-expression-after-in-vitro-differentiation-of-human-bone-marrow-derived-stem-cells-to-insulin-producing-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85954.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">216</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">320</span> Epilepsy Seizure Prediction by Effective Connectivity Estimation Using Granger Causality and Directed Transfer Function Analysis of Multi-Channel Electroencephalogram</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Hejazi">Mona Hejazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Motie%20Nasrabadi"> Ali Motie Nasrabadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epilepsy is a persistent neurological disorder that affects more than 50 million people worldwide. Hence, there is a necessity to introduce an efficient prediction model for making a correct diagnosis of the epileptic seizure and accurate prediction of its type. In this study we consider how the Effective Connectivity (EC) patterns obtained from intracranial Electroencephalographic (EEG) recordings reveal information about the dynamics of the epileptic brain and can be used to predict imminent seizures, as this will enable the patients (and caregivers) to take appropriate precautions. We use this definition because we believe that effective connectivity near seizures begin to change, so we can predict seizures according to this feature. Results are reported on the standard Freiburg EEG dataset which contains data from 21 patients suffering from medically intractable focal epilepsy. Six channels of EEG from each patients are considered and effective connectivity using Directed Transfer Function (DTF) and Granger Causality (GC) methods is estimated. We concentrate on effective connectivity standard deviation over time and feature changes in five brain frequency sub-bands (Alpha, Beta, Theta, Delta, and Gamma) are compared. The performance obtained for the proposed scheme in predicting seizures is: average prediction time is 50 minutes before seizure onset, the maximum sensitivity is approximate ~80% and the false positive rate is 0.33 FP/h. DTF method is more acceptable to predict epileptic seizures and generally we can observe that the greater results are in gamma and beta sub-bands. The research of this paper is significantly helpful for clinical applications, especially for the exploitation of online portable devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effective%20connectivity" title="effective connectivity">effective connectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Granger%20causality" title=" Granger causality"> Granger causality</a>, <a href="https://publications.waset.org/abstracts/search?q=directed%20transfer%20function" title=" directed transfer function"> directed transfer function</a>, <a href="https://publications.waset.org/abstracts/search?q=epilepsy%20seizure%20prediction" title=" epilepsy seizure prediction"> epilepsy seizure prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a> </p> <a href="https://publications.waset.org/abstracts/51480/epilepsy-seizure-prediction-by-effective-connectivity-estimation-using-granger-causality-and-directed-transfer-function-analysis-of-multi-channel-electroencephalogram" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51480.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">469</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">319</span> Repositioning Sodium Valproate for Amelioration of Bleomycin-induced Scleroderma: The Role of Oxidative Stress, Transforming Growth Factor Beta-1, and the Mammalian Target of Rapamycin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Kabel">Ahmed M.

Its pathogenesis involves multiple interrelated processes of autoimmunity, vasculopathy, inflammation, and oxidative stress. This study was a trial to explore the possible ameliorative effects of sodium valproate on an experimental model of skin fibrosis induced by bleomycin. Forty male BALB/c mice were divided into four equal groups as follows: control group; bleomycin group; bleomycin + sodium valproate group, and sodium valproate group. Mice were assessed for their body weight every four days throughout the whole study. Skin tissues were used to evaluate the oxidative stress parameters, transforming growth factor beta 1 (TGF-β1), tumor necrosis factor alpha (TNF-α), interleukin 15, and mammalian target of rapamycin (mTOR). Skin fibrosis was evaluated by measuring dermal thickness and staining the skin tissues with Masson trichrome stain. Also, the skin tissues were immunostained with alpha smooth muscle actin (α-SMA). Administration of sodium valproate to bleomycin-treated mice resulted in the restoration of the body weight with a significant decrease in the dermal thickness, amelioration of oxidative stress, suppression of TGF-β1 and mTOR expression, and significant reduction of the percentage of α-SMA immunostaining and the proinflammatory cytokine levels compared to mice treated with bleomycin alone. In conclusion, sodium valproate has an antifibrotic effect on skin fibrosis which may represent a beneficial therapeutic modality for the management of scleroderma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scleroderma" title="scleroderma">scleroderma</a>, <a href="https://publications.waset.org/abstracts/search?q=bleomycin" title=" bleomycin"> bleomycin</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20valproate" title=" sodium valproate"> sodium valproate</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20fibrosis" title=" skin fibrosis"> skin fibrosis</a> </p> <a href="https://publications.waset.org/abstracts/157892/repositioning-sodium-valproate-for-amelioration-of-bleomycin-induced-scleroderma-the-role-of-oxidative-stress-transforming-growth-factor-beta-1-and-the-mammalian-target-of-rapamycin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157892.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">83</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">318</span> Comparison of Transforming Growth Factor-β1 Levels in the Human Gingival Sulcus during Canine Retraction Using Elastic Chain and Closed Coil Spring </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Suparwitri">Sri Suparwitri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When an orthodontic force is applied to a tooth, an inflammatory response is initiated then lead to bone remodeling process, and the process accommodates tooth movement. One of cytokine that plays a prominent role in bone remodeling process was transforming growth factor-beta 1 (TGF-β1). The purpose of this study was to identify and compare changes of TGF-β1 in human gingival crevicular fluid during canine retraction using elastic chain and closed coil spring. Ten patients (mean age 20.7 ± 2.9 years) participated. The patients were entering the space closure phase of fixed orthodontic treatment. An upper canine of each patient was retracted using elastic chain, and the contralateral canine was retracted using closed coil spring. Gingival crevicular fluid samples were collected from the canine teeth before and 7 days after the force was applied. Transforming growth factor-beta 1 was determined by enzyme-linked immunosorbent assay (ELISA). The concentrations of TGF-β1 at 7 days were significantly higher compared to before canine retraction in both groups. In the evaluation of between-group difference, before retraction, the difference was insignificant, whereas at 7 days significantly higher values were determined in the closed coil spring group compared to elastic chain group. The result suggests that TGF-β1 is associated with the bone remodeling that occurs during canine distalization movement. Closed coil spring gave higher TGF-β1 concentrations thus more bone remodeling occurred and may be considered the treatment of choice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=closed%20coil%20spring" title="closed coil spring">closed coil spring</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20chain" title=" elastic chain"> elastic chain</a>, <a href="https://publications.waset.org/abstracts/search?q=gingival%20crevicular%20fluid" title=" gingival crevicular fluid"> gingival crevicular fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=TGF-%CE%B21" title=" TGF-β1"> TGF-β1</a> </p> <a href="https://publications.waset.org/abstracts/75727/comparison-of-transforming-growth-factor-v1-levels-in-the-human-gingival-sulcus-during-canine-retraction-using-elastic-chain-and-closed-coil-spring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75727.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">171</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">317</span> Parameter and Lose Effect Analysis of Beta Stirling Cycle Refrigerating Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muluken%20Z.%20Getie">Muluken Z.

First, the developed numerical model incorporates into the ideal adiabatic analysis, the shuttle heat transfer (heat loss from compression space to expansion space), and gas leakage from the working space to the buffer space into the crankcase. The other losses that may not have a direct effect on the temperature and pressure of working fluid are simply incorporated in a simple analysis. The model is then validated by reversing the model to the engine model and compared with other literature results using (GPU-3) engine. After validating the model with other engine model and experiment results, analysis of the effect of phase angle, shuttle heat lose and gas leakage on temperature, pressure, and performance (power requirement, cooling capacity and coefficient of performance) of refrigerating machine considering the FEMTO 60 Stirling engine as a case study have been conducted. Shuttle heat loss has a greater effect on the temperature of working gas; gas leakage to the crankcase has more effect on the pressure of working spaces and hence both have a considerable impact on the performance of the Stirling cycle refrigerating machine. The optimum coefficient of performance exists between phase angles of 900-950, and optimum cooling capacity could be found between phase angles of 950-980. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%20configuration" title="beta configuration">beta configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20model" title=" engine model"> engine model</a>, <a href="https://publications.waset.org/abstracts/search?q=moderate%20cooling" title=" moderate cooling"> moderate cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=stirling%20refrigerator" title=" stirling refrigerator"> stirling refrigerator</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20validation" title=" and validation"> and validation</a> </p> <a href="https://publications.waset.org/abstracts/120316/parameter-and-lose-effect-analysis-of-beta-stirling-cycle-refrigerating-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120316.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">102</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">316</span> Association between Polygenic Risk of Alzheimer's Dementia, Brain MRI and Cognition in UK Biobank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachana%20Tank">Rachana Tank</a>, <a href="https://publications.waset.org/abstracts/search?q=Donald.%20M.%20Lyall"> Donald.

However, individuals experience considerable cognitive deficits and brain pathology over decades before reaching clinically diagnosable LOAD and studies have utilised gene candidate studies such as genome wide association studies (GWAS) and polygenic risk (PGR) scores to identify high risk individuals and potential pathways. This investigation aims to determine whether high genetic risk of LOAD is associated with worse brain MRI and cognitive performance in healthy older adults within the UK Biobank cohort. Previous studies investigating associations of PGR for LOAD and measures of MRI or cognitive functioning have focused on specific aspects of hippocampal structure, in relatively small sample sizes and with poor ‘controlling’ for confounders such as smoking. Both the sample size of this study and the discovery GWAS sample are bigger than previous studies to our knowledge. Genetic interaction between loci showing largest effects in GWAS have not been extensively studied and it is known that APOE e4 poses the largest genetic risk of LOAD with potential gene-gene and gene-environment interactions of e4, for this reason we also analyse genetic interactions of PGR with the APOE e4 genotype. High genetic loading based on a polygenic risk score of 21 SNPs for LOAD is associated with worse brain MRI and cognitive outcomes in healthy individuals within the UK Biobank cohort. Summary statistics from Kunkle et al., GWAS meta-analyses (case: n=30,344, control: n=52,427) will be used to create polygenic risk scores based on 21 SNPs and analyses will be carried out in N=37,000 participants in the UK Biobank. This will be the largest study to date investigating PGR of LOAD in relation to MRI. MRI outcome measures include WM tracts, structural volumes. Cognitive function measures include reaction time, pairs matching, trail making, digit symbol substitution and prospective memory. Interaction of the APOE e4 alleles and PGR will be analysed by including APOE status as an interaction term coded as either 0, 1 or 2 e4 alleles. Models will be adjusted partially for adjusted for age, BMI, sex, genotyping chip, smoking, depression and social deprivation. Preliminary results suggest PGR score for LOAD is associated with decreased hippocampal volumes including hippocampal body (standardised beta = -0.04, P = 0.022) and tail (standardised beta = -0.037, P = 0.030), but not with hippocampal head. There were also associations of genetic risk with decreased cognitive performance including fluid intelligence (standardised beta = -0.08, P<0.01) and reaction time (standardised beta = 2.04, P<0.01). No genetic interactions were found between APOE e4 dose and PGR score for MRI or cognitive measures. The generalisability of these results is limited by selection bias within the UK Biobank as participants are less likely to be obese, smoke, be socioeconomically deprived and have fewer self-reported health conditions when compared to the general population. Lack of a unified approach or standardised method for calculating genetic risk scores may also be a limitation of these analyses. Further discussion and results are pending. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%27s%20dementia" title="Alzheimer's dementia">Alzheimer's dementia</a>, <a href="https://publications.waset.org/abstracts/search?q=cognition" title=" cognition"> cognition</a>, <a href="https://publications.waset.org/abstracts/search?q=polygenic%20risk" title=" polygenic risk"> polygenic risk</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI" title=" MRI"> MRI</a> </p> <a href="https://publications.waset.org/abstracts/128951/association-between-polygenic-risk-of-alzheimers-dementia-brain-mri-and-cognition-in-uk-biobank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128951.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">114</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">315</span> The Effectiveness of Transcranial Electrical Stimulation on Brain Wave Pattern and Blood Pressure in Patients with Generalized Anxiety Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahtab%20Baghaei">Mahtab Baghaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mahmoud%20Tabatabaei"> Seyed Mahmoud Tabatabaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim & Background: Electrical stimulation of transcranial direct current is considered one of the treatment methods for mental disorders. The aim of this study was to evaluate the effectiveness of transcranial electrical stimulation on the delta, theta, alpha, beta and systolic and diastolic blood pressure in patients with generalized anxiety disorder. Materials and Methods: The present study was a double-blind intervention with a pre-test and post-test design on people with generalized anxiety disorder in Tabriz in 1400. In this study, 30 patients with generalized anxiety disorder were selected by purposive sampling method based on the criteria specified in DSM-5 and randomly divided into an experimental group (n = 15) and a control group (n = 15). The experimental group received two sessions of 30 minutes of electrical stimulation of transcranial direct current with an intensity of 2 mA in the area of the lateral dorsal prefrontal cortex, and the control group also received artificial stimulation. Results: The results showed that transcranial electrical stimulation reduces delta and theta waves and increases beta and alpha brain waves in the experimental group. On the other hand, this method also showed a significant decrease in systolic and diastolic blood pressure in these patients (p <0.01). Conclusion: The results show that transcranial electrical stimulation has a statistically significant effect on brain waves and blood pressure, and this non-invasive method can be used as one of the treatment methods in people with generalized anxiety disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transcranial%20direct%20current%20electrical%20stimulation" title="transcranial direct current electrical stimulation">transcranial direct current electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=brain%20waves" title=" brain waves"> brain waves</a>, <a href="https://publications.waset.org/abstracts/search?q=systolic%20blood%20pressure" title=" systolic blood pressure"> systolic blood pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=diastolic%20blood%20pressure" title=" diastolic blood pressure"> diastolic blood pressure</a> </p> <a href="https://publications.waset.org/abstracts/150544/the-effectiveness-of-transcranial-electrical-stimulation-on-brain-wave-pattern-and-blood-pressure-in-patients-with-generalized-anxiety-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150544.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">103</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">314</span> Biophysical Study of the Interaction of Harmalol with Nucleic Acids of Different Motifs: Spectroscopic and Calorimetric Approaches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kakali%20Bhadra">Kakali Bhadra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Binding of small molecules to DNA and recently to RNA, continues to attract considerable attention for developing effective therapeutic agents for control of gene expression. This work focuses towards understanding interaction of harmalol, a dihydro beta-carboline alkaloid, with different nucleic acid motifs viz. double stranded CT DNA, single stranded A-form poly(A), double-stranded A-form of poly(C)·poly(G) and clover leaf tRNAphe by different spectroscopic, calorimetric and molecular modeling techniques. Results of this study converge to suggest that (i) binding constant varied in the order of CT DNA > poly(C)·poly(G) > tRNAphe > poly(A), (ii) non-cooperative binding of harmalol to poly(C)·poly(G) and poly(A) and cooperative binding with CT DNA and tRNAphe, (iii) significant structural changes of CT DNA, poly(C)·poly(G) and tRNAphe with concomitant induction of optical activity in the bound achiral alkaloid molecules, while with poly(A) no intrinsic CD perturbation was observed, (iv) the binding was predominantly exothermic, enthalpy driven, entropy favoured with CT DNA and poly(C)·poly(G) while it was entropy driven with tRNAphe and poly(A), (v) a hydrophobic contribution and comparatively large role of non-polyelectrolytic forces to Gibbs energy changes with CT DNA, poly(C)·poly(G) and tRNAphe, and (vi) intercalated state of harmalol with CT DNA and poly(C)·poly(G) structure as revealed from molecular docking and supported by the viscometric data. Furthermore, with competition dialysis assay it was shown that harmalol prefers hetero GC sequences. All these findings unequivocally pointed out that harmalol prefers binding with ds CT DNA followed by ds poly(C)·poly(G), clover leaf tRNAphe and least with ss poly(A). The results highlight the importance of structural elements in these natural beta-carboline alkaloids in stabilizing different DNA and RNA of various motifs for developing nucleic acid based better therapeutic agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calorimetry" title="calorimetry">calorimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%2FRNA-alkaloid%20interaction" title=" DNA/RNA-alkaloid interaction"> DNA/RNA-alkaloid interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=harmalol" title=" harmalol"> harmalol</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopy" title=" spectroscopy"> spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/55814/biophysical-study-of-the-interaction-of-harmalol-with-nucleic-acids-of-different-motifs-spectroscopic-and-calorimetric-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55814.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">228</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">313</span> Intracranial Hypertension without CVST in Apla Syndrome: An Unique Association</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Camelia%20Porey">Camelia Porey</a>, <a href="https://publications.waset.org/abstracts/search?q=Binaya%20Kumar%20Jaiswal"> Binaya Kumar Jaiswal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BACKGROUND: Antiphospholipid antibody (APLA) syndrome is an autoimmune disorder predisposing to thrombotic complications affecting CNS either by arterial vasooclusion or venous thrombosis. Cerebral venous sinus thrombosis (CVST) secondarily causes raised intracranial pressure (ICP). However, intracranial hypertension without evidence of CVST is a rare entity. Here we present two cases of elevated ICP with absence of identifiable CVST. CASE SUMMARY: Case 1, 28-year female had a 2 months history of holocranial headache followed by bilateral painless vision loss reaching lack of light perception over 20 days. CSF opening pressure was elevated. Fundoscopy showed bilateral grade 4 papilledema. MRI revealed a partially empty sella with bilateral optic nerve tortuosity. Idiopathic intracranial hypertension (IIH) was diagnosed. With acetazolamide, there was complete resolution of the clinical and radiological abnormalities. 5 months later she presented with acute onset right-sided hemiparesis. MRI was suggestive of acute left MCA infarct.MR venogram was normal. APLA came positive with high titres of Anticardiolipin and Beta 2 glycoprotein both IgG and IgM. Case 2, 23-year female, presented with headache and diplopia of 2 months duration. CSF pressure was elevated and Grade 3 papilledema was seen. MRI showed bilateral optic nerve hyperintensities with nerve head protrusion with normal MRV. APLA profile showed elevated beta 2 glycoprotein IgG and IgA. CONCLUSION: This is an important non thrombotic complication of APLA syndrome and requires further large-scale study for insight into the pathogenesis and early recognition to avoid future complications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=APLA%20syndrome" title="APLA syndrome">APLA syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=idiopathic%20intracranial%20hypertension" title=" idiopathic intracranial hypertension"> idiopathic intracranial hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=MR%20venogram" title=" MR venogram"> MR venogram</a>, <a href="https://publications.waset.org/abstracts/search?q=papilledema" title=" papilledema"> papilledema</a> </p> <a href="https://publications.waset.org/abstracts/147679/intracranial-hypertension-without-cvst-in-apla-syndrome-an-unique-association" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147679.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">180</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">312</span> Development of Polylactic Acid Insert with a Cinnamaldehyde-Betacyclodextrin Complex for Cape Gooseberry (Physalis Peruviana L.)

Lizeth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cape gooseberry is a climacteric fruit; Colombia is one of the principal exporters in the world. The environmental condition of temperature and relative moisture decreases the titratable acidity and pH. These conditions and fruit maturation result in the fungal proliferation of Botrytis cinerea disease. Plastic packaging for fresh cape gooseberries was used for mechanical damage protection but created a suitable atmosphere for fungal growth. Beta-cyclodextrins are currently implemented as coatings for the encapsulation of hydrophobic compounds, for example, with bioactive compounds from essential oils such as cinnamaldehyde, which has a high antimicrobial capacity. However, it is a volatile substance. In this article, the casting method was used to obtain a polylactic acid (PLA) polymer film containing the beta-cyclodextrin-cinnamaldehyde inclusion complex, generating an insert that allowed the controlled release of the antifungal substance in packed cape gooseberries to decrease contamination by Botrytis cinerea in a latent state during storage. For the encapsulation technique, three ratios for the cinnamaldehyde: beta-cyclodextrin inclusion complex were proposed: (25:75), (40:60), and (50:50). Spectrophotometry, colorimetry in L*a*b* coordinate space and scanning electron microscopy (SEM) were made for the complex characterization. Subsequently, two ratios of tween and water (40:60) and (50:50) were used to obtain the polylactic acid (PLA) film. To determine mechanical and physical parameters of colourimetry in L*a*b* coordinate space, atomic force microscopy and stereoscopy were done to determine the transparency and flexibility of the film; for both cases, Statgraphics software was used to determine the best ratio in each of the proposed phases, where for encapsulation it was (50:50) with an encapsulation efficiency of 65,92%, and for casting the ratio (40:60) obtained greater transparency and flexibility that permitted its incorporation into the polymeric packaging. A liberation assay was also developed under ambient temperature conditions to evaluate the concentration of cinnamaldehyde inside the packaging through gas chromatography for three weeks. It was found that the insert had a controlled release. Nevertheless, a higher cinnamaldehyde concentration is needed to obtain the minimum inhibitory concentration for the fungus Botrytis cinerea (0.2g/L). The homogeneity of the cinnamaldehyde gas phase inside the packaging can be improved by considering other insert configurations. This development aims to impact emerging food preservation technologies with the controlled release of antifungals to reduce the affectation of the physico-chemical and sensory properties of the fruit as a result of contamination by microorganisms in the postharvest stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifungal" title="antifungal">antifungal</a>, <a href="https://publications.waset.org/abstracts/search?q=casting" title=" casting"> casting</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=postharvest" title=" postharvest"> postharvest</a> </p> <a href="https://publications.waset.org/abstracts/163516/development-of-polylactic-acid-insert-with-a-cinnamaldehyde-betacyclodextrin-complex-for-cape-gooseberry-physalis-peruviana-l-packed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163516.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">75</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">311</span> Linear Decoding Applied to V5/MT Neuronal Activity on Past Trials Predicts Current Sensory Choices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ben%20Hadj%20Hassen%20Sameh">Ben Hadj Hassen Sameh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaillard%20Corentin"> Gaillard Corentin</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Parker"> Andrew Parker</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristine%20Krug"> Kristine Krug</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perceptual decisions about sequences of sensory stimuli often show serial dependence. The behavioural choice on one trial is often affected by the choice on previous trials. We investigated whether the neuronal signals in extrastriate visual area V5/MT on preceding trials might influence choice on the current trial and thereby reveal the neuronal mechanisms of sequential choice effects. We analysed data from 30 single neurons recorded from V5/MT in three Rhesus monkeys making sequential choices about the direction of rotation of a three-dimensional cylinder. We focused exclusively on the responses of neurons that showed significant choice-related firing (mean choice probability =0.73) while the monkey viewed perceptually ambiguous stimuli. Application of a wavelet transform to the choice-related firing revealed differences in the frequency band of neuronal activity that depended on whether the previous trial resulted in a correct choice for an unambiguous stimulus that was in the neuron’s preferred direction (low alpha and high beta and gamma) or non-preferred direction (high alpha and low beta and gamma). To probe this in further detail, we applied a regularized linear decoder to predict the choice for an ambiguous trial by referencing the neuronal activity of the preceding unambiguous trial. Neuronal activity on a previous trial provided a significant prediction of the current choice (61% correc, 95%Cl~52%t), even when limiting analysis to preceding trials that were correct and rewarded. These findings provide a potential neuronal signature of sequential choice effects in the primate visual cortex. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perception" title="perception">perception</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a>, <a href="https://publications.waset.org/abstracts/search?q=decoding" title=" decoding"> decoding</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20system" title=" visual system"> visual system</a> </p> <a href="https://publications.waset.org/abstracts/154327/linear-decoding-applied-to-v5mt-neuronal-activity-on-past-trials-predicts-current-sensory-choices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154327.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">310</span> Job Satisfaction and Motivation as Predictors of Lecturers' Effectiveness in Nigeria Police Academy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bibire%20Abdulkareem%20Hussein">Bibire Abdulkareem Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Job satisfaction and motivation are considered as major tools in sustaining institutional development, they are also the machinery used to achieve an institutional goals and objectives. However, it has been observed that some institutions failed in motivating and stimulating their workers; in contrast, workers may be motivated but not satisfied with the job and failed to perform efficiently and effectively. It is hoped that the study of this nature would be of significance value to all stakeholders in education specifically, lecturers in higher institutions in Nigeria. Also it significances will enhance lecturers’ effectiveness and performance in discharging their duties. It is against this backdrop that, this study investigated whether job satisfaction and motivation predict lecturers’ effectiveness in Nigeria Police Academy, Wudil, KanoState. The correlational research method was adopted for the study while purposive sampling technique was used to choose the institution and the sampled lectures (70). Simple random sampling technique was used to select one hundred cadets across the academy. Two instruments were used to elicit information from both lecturers and cadets. These were job satisfaction and motivation; and lecturers’ effectiveness Questionnaires. The instruments were subjected to pilot testing and found to have reliability coefficient of 0.69 and 0.71 respectively. The results of the study revealed that there was a significance relationship among job satisfaction, motivation and lecturers effectiveness in Nigeria Police Academy, Job satisfaction had a Beta weight (β) of .125, t = 3.253, p<0.05, Job motivation had a Beta weight (β) of .185, t = 3.849, p<0.05. There was a significance relationship between job satisfaction and lecturers’ effectiveness in Nigeria Police Academy the cal r is 0.21 while the crt r is 0.19. at p<0.05 and; there was a significance relationship between job motivation and lecturers effectiveness in Nigeria Police Academy the cal r is 0.20 while the crt r is 0.19 at p<0.05This study therefore concluded that there was a significance relationship among job satisfaction, motivation and lecturers effectiveness in Nigeria Police Academy s,In view of the findings of this study, the paper recommends that lecturers should be more pro-active and more effective in their primary assignment (teaching) in order to make meaningful impacts and inputs in the life of cadets and boost the standard of the academy. In the same vein, it is recommended that management should intensify efforts to improve lecturers’ welfares by providing more motivational techniques to enhance more productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academy" title="academy">academy</a>, <a href="https://publications.waset.org/abstracts/search?q=lecturers%20effectiveness" title=" lecturers effectiveness"> lecturers effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title=" satisfaction"> satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/32428/job-satisfaction-and-motivation-as-predictors-of-lecturers-effectiveness-in-nigeria-police-academy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32428.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">472</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">309</span> Susceptibility of Spodoptera littoralis, Field Populations in Egypt to Chlorantraniliprole and the Role of Detoxification Enzymes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20H.%20Khalifa">Mohamed H.

Chlorantraniliprole has been registered recently in Egypt for control this insect. The susceptibilities of three <em>S. littoralis</em> populations collected from El Behaira governorate, north Egypt to chlorantraniliprole were determined by leaf-dipping technique on 4<sup>th</sup> instar larvae. Obvious variation of toxicity was observed among the laboratory susceptible, and three field populations with LC<sub>50</sub> values ranged between 1.53 µg/ml and 6.22 µg/ml. However, all the three field populations were less susceptible to chlorantraniliprole than a laboratory susceptible population. The most tolerant populations were sampled from El Delengat (ED) Province where <em>S. littoralis</em> had been frequently challenged by insecticides. Certain enzyme activity assays were carried out to be correlated with the mechanism of the observed field population tolerance. All field populations showed significantly enhanced activities of detoxification enzymes compared with the susceptible strain. The regression analysis between chlorantraniliprole toxicities and enzyme activities revealed that the highest correlation is between α-esterase or β-esterase (α-β-EST) activity and collected field strains susceptibility, otherwise this correlation is not significant (P > 0.05). Synergism assays showed the ED and susceptible strains could be synergized by known detoxification inhibitors such as piperonyl butoxide (PBO), triphenyl phosphate (TPP) and diethyl-maleate (DEM) at different levels (1.01-8.76-fold and 1.09-2.94 fold, respectively), TPP showed the maximum synergism in both strains. The results show that there is a correlation between the enzyme activity and tolerance, and carboxylic-esterase (Car-EST) is likely the main detoxification mechanism responsible for tolerance of <em>S. littoralis</em> to chlorantraniliprole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlorantraniliprole" title="chlorantraniliprole">chlorantraniliprole</a>, <a href="https://publications.waset.org/abstracts/search?q=detoxification%20enzymes" title=" detoxification enzymes"> detoxification enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=Spodoptera%20littoralis" title=" Spodoptera littoralis"> Spodoptera littoralis</a> </p> <a href="https://publications.waset.org/abstracts/62316/susceptibility-of-spodoptera-littoralis-field-populations-in-egypt-to-chlorantraniliprole-and-the-role-of-detoxification-enzymes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62316.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">277</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">308</span> Obtaining Composite Cotton Fabric by Cyclodextrin Grafting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20K.%20Sahin">U.

Especially, by the addition or impartation of nano-scaled particles to the fabric structure composite fabrics, a kind of composite materials can be acquired. Composite materials, generally shortened as composites or in other words composition materials, are engineered or naturally occurring materials made from two or more component materials with significantly different physical, mechanical or chemical characteristics remaining separate and distinctive at the macroscopic or microscopic scale within the end product structure. Therefore, the technique finishing which is one of the fundamental methods to be applied on fabrics for obtainment of composite fabrics with many functionalities was used in the current study with the same purpose. However, regardless of the finishing materials applied, the efficient life of finished product on offering desired feature is low, since the durability of finishes on the material is limited. Any increase in durability of these finishes on textiles would enhance the life of use for textiles, which will result in happier users. Therefore, in this study, since higher durability was desired for the finishing materials fixed on the fabrics, nano-scaled hollow structured cyclodextrins were chemically imparted by grafting to the structure of conventional cotton fabrics by the help of finishing technique in order to be fixed permanently. By this way, a processed and functionalized base fabric having potential to be treated in the subsequent processes with many different finishing agents and nanomaterials could be obtained. Henceforth, this fabric can be used as a multi-functional fabric due to the encapturing ability of cyclodextrins to molecules/particles via physical/chemical means. In this study, scoured and rinsed woven bleached plain weave 100% cotton fabrics were utilized because textiles made of cotton are the most demanded textile products in the textile market by the textile consumers in daily life. Cotton fabric samples were immersed in treating baths containing β-cyclodextrin and 1,2,3,4-butanetetracarboxylic acid and to reduce the curing temperature the catalyst sodium hypophosphite monohydrate was used. All impregnated fabric samples were pre-dried. The reaction of grafting was performed in dry state. The treated and cured fabric samples were rinsed with warm distilled water and dried. The samples were dried for 4 h and weighed before and after finishing and rinsing. Stability and durability of β-cyclodextrins on fabric surface against external factors such as washing as well as strength of functionalized fabric in terms of tensile and tear strength were tested. Presence and homogeneity of distribution of β-cyclodextrins on fabric surface were characterized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cotton%20fabric" title="cotton fabric">cotton fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclodextrine" title=" cyclodextrine"> cyclodextrine</a>, <a href="https://publications.waset.org/abstracts/search?q=improved%20durability" title=" improved durability"> improved durability</a>, <a href="https://publications.waset.org/abstracts/search?q=multifunctional%20composite%20textile" title=" multifunctional composite textile"> multifunctional composite textile</a> </p> <a href="https://publications.waset.org/abstracts/43878/obtaining-composite-cotton-fabric-by-cyclodextrin-grafting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43878.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">297</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">307</span> Research on the Role of Platelet Derived Growth Factor Receptor Beta in Promoting Dedifferentiation and Pulmonary Metastasis of Osteosarcoma Under Hypoxic Microenvironment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enjie%20Xu">Enjie Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen%20Huang"> Zhen Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunpeng%20Zhu"> Kunpeng Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianping%20Hu"> Jianping Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaolong%20Ma"> Xiaolong Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongjie%20Wang"> Yongjie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiazhuang%20Zhu"> Jiazhuang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chunlin%20Zhang"> Chunlin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract: Hypoxia and dedifferentiation of osteosarcoma (OS) cells leads to poor prognosis.

We obtained PDGFRB knockdown and overexpression cells through lentiviral infection experiments and the effects of PDGFRB on cytoskeleton rearrangement and cell adhesion were explored by immunocytochemistry. Wound-healing experiments, transwell assays, and animal trials were employed to investigate the effect of PDGFRB on OS metastasis. Dedifferentiated OS cells were found to exhibit high expression of HIF1A and PDGFRB, and HIF1A promoted the expression of PDGFRB, subsequently activated ras homolog family member A (RhoA), and increased the phosphorylation of myosin light chain (MLC). PDGFRB also enhanced the phosphorylation of focal adhesion kinase (FAK). The OS cell morphology and vinculin distribution were altered by PDGFRB. PDGFRB also promoted cell dedifferentiation and had a significant impact on the metastasis of OS cells both in vitro and in vivo. Our results demonstrated that HIF1A up-regulated PDGFRB under hypoxic conditions, and PDGFRB regulated the actin cytoskeleton by activating RhoA and subsequently phosphorylating MLC, thereby promoting OS dedifferentiation and pulmonary metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title="osteosarcoma">osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=dedifferentiation" title=" dedifferentiation"> dedifferentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytoskeleton%20rearrangement" title=" cytoskeleton rearrangement"> cytoskeleton rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=PDGFRB" title=" PDGFRB"> PDGFRB</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia" title=" hypoxia"> hypoxia</a> </p> <a href="https://publications.waset.org/abstracts/184648/research-on-the-role-of-platelet-derived-growth-factor-receptor-beta-in-promoting-dedifferentiation-and-pulmonary-metastasis-of-osteosarcoma-under-hypoxic-microenvironment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184648.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">47</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">306</span> The Association between IFNAR2 and Dpp9 Genes Single Nucleotide Polymorphisms Frequency with COVID-19 Severity in Iranian Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sima%20Parvizi%20Omran">Sima Parvizi Omran</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezvan%20Tavakoli"> Rezvan Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahnaz%20Safari"> Mahnaz Safari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Aghasadeghi"> Mohammadreza Aghasadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolfazl%20Fateh"> Abolfazl Fateh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooneh%20Rahimi"> Pooneh Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: SARS-CoV-2, a single-stranded RNA betacoronavirus causes the global outbreak of coronavirus disease 2019 (COVID-19). Several clinical and scientific concerns are raised by this pandemic. Genetic factors can contribute to pathogenesis and disease susceptibility. There are single nucleotide polymorphisms (SNPs) in many of the genes in the immune system that affect the expression of specific genes or functions of some proteins related to immune responses against viral infections. In this study, we analyzed the impact of polymorphism in the interferon alpha and beta receptor subunit 2 (IFNAR2) and dipeptidyl peptidase 9 (Dpp9) genes and clinical parameters on the susceptibility and resistance to Coronavirus disease (COVID-19). Methods: A total of 330- SARS-CoV-2 positive patients (188 survivors and 142 nonsurvivors) were included in this study. All single-nucleotide polymorphisms (SNPs) on IFNAR2 (rs2236757) and Dpp9 (rs2109069) were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: In survivor patients, the frequency of the favourable genotypes of IFNAR2 SNP (rs2236757 GC) was significantly higher than in nonsurvivor patients, and also Dpp9 (rs2109069 AT) genotypes were associated with the severity of COVID-19 infection. Conclusions: This study demonstrated that the severity of COVID- 19 patients was strongly associated with clinical parameters and unfavourable IFNAR2, Dpp9 SNP genotypes. In order to establish the relationship between host genetic factors and the severity of COVID-19 infection, further studies are needed in multiple parts of the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title="SARS-CoV-2">SARS-CoV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=interferon%20alpha%20and%20beta%20receptor%20subunit%202" title=" interferon alpha and beta receptor subunit 2"> interferon alpha and beta receptor subunit 2</a>, <a href="https://publications.waset.org/abstracts/search?q=dipeptidyl%20peptidase%209" title=" dipeptidyl peptidase 9"> dipeptidyl peptidase 9</a>, <a href="https://publications.waset.org/abstracts/search?q=single-nucleotide%20polymorphisms" title=" single-nucleotide polymorphisms"> single-nucleotide polymorphisms</a> </p> <a href="https://publications.waset.org/abstracts/155792/the-association-between-ifnar2-and-dpp9-genes-single-nucleotide-polymorphisms-frequency-with-covid-19-severity-in-iranian-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155792.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">164</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">305</span> Evaluation of Some Serum Proteins as Markers for Myeloma Bone Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20T.%20Gerov">V.

Myeloma bone disease (MBD) is characterized by osteolytic bone lesions as a result of increased osteoclasts activity not followed by reactive bone formation due to osteoblasts suppression. Skeletal complications cause significant adverse effects on quality of life and lead to increased morbidity and mortality. Last decade studies revealed the implication of different proteins in osteoclast activation and osteoblast inhibition. The aim of the present study was to determine serum levels of periostin, sRANKL and osteopontin and to evaluate their role as bone markers in MBD. Materials and methods. Thirty-two newly diagnosed MM patients (mean age: 62.2 ± 10.7 years) and 33 healthy controls (mean age: 58.9 ± 7.5 years) were enrolled in the study. According to IMWG criteria 28 patients were with symptomatic MM and 4 with monoclonal gammopathy of undetermined significance (MGUS). In respect to their bone involvement all symptomatic patients were divided into two groups (G): 9 patients with 0-3 osteolytic lesions (G1) and 19 patients with >3 osteolytic lesions and/or pathologic fractures (G2). Blood samples were drawn for routine laboratory analysis and for measurement of periostin, sRANKL and osteopontin serum levels by ELISA kits (Shanghai Sunred Biological Technology, China). Descriptive analysis, Mann-Whitney test for assessment the differences between groups and non-parametric correlation analysis were performed using GraphPad Prism v8.01. Results. The median serum levels of periostin, sRANKL and osteopontin of ММ patients were significantly higher compared to controls (554.7pg/ml (IQR=424.0-720.6) vs 396.9pg/ml (IQR=308.6-471.9), p=0.0001; 8.9pg/ml (IQR=7.1-10.5) vs 5.6pg/ml (IQR=5.1-6.4, p<0.0001 and 514.0ng/ml (IQR=469.3-754.0) vs 387.0ng/ml (IQR=335.9-441.9), p<0.0001, respectively). for assessment of differences between groups and non-parametric correlation analysis were performed using GraphPad Prism v8.01. Statistical significance was found for all tested bone markers between symptomatic MM patients and controls: G1 vs controls (p<0.03), G2 vs controls (p<0.0001) for periostin; G1 vs controls (p<0.0001), G2 vs controls (p<0.0001) for sRANKL; G1 vs controls (p=0.002), G2 vs controls (p<0.0001) for osteopontin, as well between symptomatic MM patients and MGUS patients: G1 vs MGUS (p<0.003), G2 vs MGUS (p=0.003) for periostin; G1 vs MGUS (p<0.05), G2 vs MGUS (p<0.001) for sRANKL; G1 vs MGUS (p=0.011), G2 vs MGUS (p=0.0001) for osteopontin. No differences were detected between MGUS and controls and between patients in G1 and G2 groups. Spearman correlation analysis revealed moderate positive correlation between periostin and beta-2-microglobulin (r=0.416, p=0.018), percentage bone marrow myeloma PC (r=0.432, p=0.014), and serum total protein (r=0.427, p=0.015). Osteopontin levels were also positively related to beta-2-microglobulin (r=0.540, p=0.0014), percentage bone marrow myeloma PC (r=0.423, p=0.016), and serum total protein (r=0.413, p=0.019). Serum sRANKL was only related to beta-2-microglobulin levels (r=0.398, p=0.024). Conclusion: In the present study, serum levels of periostin, sRANKL and osteopontin in newly diagnosed MM patients were evaluated. They gradually increased from MGUS to more advanced stages of MM reflecting the severity of bone destruction. These results support the idea that some new protein markers could be used in monitoring the MBD as a most severe complication of MM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myeloma%20bone%20disease" title="myeloma bone disease">myeloma bone disease</a>, <a href="https://publications.waset.org/abstracts/search?q=periostin" title=" periostin"> periostin</a>, <a href="https://publications.waset.org/abstracts/search?q=sRANKL" title=" sRANKL"> sRANKL</a>, <a href="https://publications.waset.org/abstracts/search?q=osteopontin" title=" osteopontin"> osteopontin</a> </p> <a href="https://publications.waset.org/abstracts/150826/evaluation-of-some-serum-proteins-as-markers-for-myeloma-bone-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150826.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">58</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">304</span> The Response of Soil Biodiversity to Agriculture Practice in Rhizosphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yan%20Wang">Yan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Guowei%20Chen"> Guowei Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Gang%20Wang"> Gang Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil microbial diversity is one of the important parameters to assess the soil fertility and soil health, even stability of the ecosystem. In this paper, we aim to reveal the soil microbial difference in rhizosphere and root zone, even to pick the special biomarkers influenced by the long term tillage practices, which included four treatments of no-tillage, ridge tillage, continuous cropping with corn and crop rotation with corn and soybean. Here, high-throughput sequencing was performed to investigate the difference of bacteria in rhizosphere and root zone. The results showed a very significant difference of species richness between rhizosphere and root zone soil at the same crop rotation system (p < 0.01), and also significant difference of species richness was found between continuous cropping with corn and corn-soybean rotation treatment in the rhizosphere statement, no-tillage and ridge tillage in root zone soils. Implied by further beta diversity analysis, both tillage methods and crop rotation systems influence the soil microbial diversity and community structure in varying degree. The composition and community structure of microbes in rhizosphere and root zone soils were clustered distinctly by the beta diversity (p < 0.05). Linear discriminant analysis coupled with effect size (LEfSe) analysis of total taxa in rhizosphere picked more than 100 bacterial taxa, which were significantly more abundant than that in root zone soils, whereas the number of biomarkers was lower between the continuous cropping with corn and crop rotation treatment, the same pattern was found at no-tillage and ridge tillage treatment. Bacterial communities were greatly influenced by main environmental factors in large scale, which is the result of biological adaptation and acclimation, hence it is beneficial for optimizing agricultural practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tillage%20methods" title="tillage methods">tillage methods</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarker" title=" biomarker"> biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizosphere" title=" rhizosphere"> rhizosphere</a> </p> <a href="https://publications.waset.org/abstracts/99559/the-response-of-soil-biodiversity-to-agriculture-practice-in-rhizosphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99559.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">166</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">303</span> Prevalence of Clostridium perfringens β2-Toxin in Type a Isolates of Sheep and Goats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mudassar%20Mohiuddin">Mudassar Mohiuddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Iqbal"> Zahid Iqbal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Clostridium perfringens is an important pathogen responsible for causing enteric diseases in both human and animals. The bacteria produce several toxins. These toxins play vital role in the pathogenesis of various fatal enteric diseases and are classified into five types, on the basis of the differential production of Alpha, Beta, Epsilon and Iota toxins. In addition to the so-called major toxins, there are other toxins like beta2 toxin, produced by some strains of C. perfringens which may play a role in the pathogenesis of disease. Aim of the study: In this study a multiplex PCR assay was developed and used for detection of cpb2 gene to identify the Beta2 harboring isolates among different types of C. perfringens. Objectives: The primary objective of this study was to identify the prevalence of β2-toxin gene in local isolates of Clostridium perfringens. Methodology: This was an experimental study. Random sampling technique was used. A total of 97 sheep and goats were included in this study. All were Pakistani local breeds. The samples were collected during the period from Sep, 2014 to Mar, 2015 from selected districts of Punjab province (Pakistan). Faecal samples were cultured in cooked meat media. The identification of Clostridium perfringens was made on the basis of biochemical tests. Multiplex PCR was performed to identify the toxin genes. Results: A total of 43 C. perfringens isolates were genotyped using multiplex PCR assay. The gene encoding C. perfringens β2-toxin (cpb2) was present in more than 50% of the isolates genotyped. However, the prevalence of this gene varied between sheep and goat isolates. Conclusion: The present study suggests the high occurrence of C. perfringens b2-toxin (cpb2) in the local isolates of Pakistan. As β2-toxin is present in both healthy and diseased animals, so further studies are suggested to establish the role of β2-toxin in pathogenesis of the clostridial enteric diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%202%20toxin%20gene" title="beta 2 toxin gene">beta 2 toxin gene</a>, <a href="https://publications.waset.org/abstracts/search?q=clostridium%20perfringens" title=" clostridium perfringens"> clostridium perfringens</a>, <a href="https://publications.waset.org/abstracts/search?q=enteric%20diseases" title=" enteric diseases"> enteric diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=goats" title=" goats"> goats</a>, <a href="https://publications.waset.org/abstracts/search?q=multiplex%20PCR" title=" multiplex PCR"> multiplex PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a> </p> <a href="https://publications.waset.org/abstracts/36854/prevalence-of-clostridium-perfringens-v2-toxin-in-type-a-isolates-of-sheep-and-goats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36854.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">463</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">302</span> The Impact of Efflux Pump Inhibitor on the Activity of Benzosiloxaboroles and Benzoxadiboroles against Gram-Negative Rods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20E.%20Laudy">Agnieszka E.

The first important compounds, 5-fluoro-1,3-dihydro-1-hydroxy-2,1-benzoxaborole and 5-chloro-1,3-dihydro-1-hydroxy-2,1-benzoxaborole were identified as potent antifungal agents. In contrast, (S)-3-(aminomethyl)-7-(3-hydroxypropoxy)-1-hydroxy-1,3-dihydro-2,1-benzoxaborole hydrochloride is in the second phase of clinical trials as a drug for the treatment of Gram-negative bacterial infections of the Enterobacteriaceae family and Pseudomonas aeruginosa. Equally important and difficult task is to search for compounds active against Gram-negative bacilli, which have multi-drug-resistance efflux pumps actively removing many of the antibiotics from bacterial cells. We have examined whether halogen-substituted benzoxaborole-based derivatives and their analogues possess antibacterial activity and are substrates for multi-drug-resistance efflux pumps. The antibacterial activity of 1,3-dihydro-3-hydroxy-1,1-dimethyl-1,2,3-benzosiloxaborole and 10 halogen-substituted its derivatives, as well as 1,2-phenylenediboronic acid and 3 synthesised fluoro-substituted its analogs, were evaluated. The activity against the reference strains of Gram-positive (n=5) and Gram-negative bacteria (n=10) was screened by the disc-diffusion test (0.4 mg of tested compounds was applied onto paper disc). The minimal inhibitory concentration values and the minimal bactericidal concentration values were estimated according to The Clinical and Laboratory Standards Institute and The European Committee on Antimicrobial Susceptibility Testing recommendations. During the minimal inhibitory concentration values determination with or without phenylalanine-arginine beta-naphthylamide (50 mg/L) efflux pump inhibitor, the concentrations of tested compounds ranged 0.39-400 mg/L in the broth medium supplemented with 1 mM magnesium sulfate. Generally, the studied benzosiloxaboroles and benzoxadiboroles showed a higher activity against Gram-positive cocci than against Gram-negative rods. Moreover, benzosiloxaboroles have the higher activity than benzoxadiboroles compounds. In this study, we demonstrated that substitution (mono-, di- or tetra-) of 1,3-dihydro-3-hydroxy-1,1-dimethyl-1,2,3-benzosiloxaborole with halogen groups resulted in an increase in antimicrobial activity as compared to the parent substance. Interestingly, the 6,7-dichloro-substituted parent substance was found to be the most potent against Gram-positive cocci: Staphylococcus sp. (minimal inhibitory concentration 6.25 mg/L) and Enterococcus sp. (minimal inhibitory concentration 25 mg/L). On the other hand, mono- and dichloro-substituted compounds were the most actively removed by efflux pumps present in Gram-negative bacteria mainly from Enterobacteriaceae family. In the presence of efflux pump inhibitor the minimal inhibitory concentration values of chloro-substituted benzosiloxaboroles decreased from 400 mg/L to 3.12 mg/L. Of note, the highest increase in bacterial susceptibility to tested compounds in the presence of phenylalanine-arginine beta-naphthylamide was observed for 6-chloro-, 6,7-dichloro- and 6,7-difluoro-substituted benzosiloxaboroles. In the case of Escherichia coli, Enterobacter cloacae and P. aeruginosa strains at least a 32-fold decrease in the minimal inhibitory concentration values of these agents were observed. These data demonstrate structure-activity relationships of the tested derivatives and highlight the need for further search for benzoxaboroles and related compounds with significant antimicrobial properties. Moreover, the influence of phenylalanine-arginine beta-naphthylamide on the susceptibility of Gram-negative rods to studied benzosiloxaboroles indicate that some tested agents are substrates for efflux pumps in Gram-negative rods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=benzosiloxaboroles" title=" benzosiloxaboroles"> benzosiloxaboroles</a>, <a href="https://publications.waset.org/abstracts/search?q=efflux%20pumps" title=" efflux pumps"> efflux pumps</a>, <a href="https://publications.waset.org/abstracts/search?q=phenylalanine-arginine%20beta-naphthylamide" title=" phenylalanine-arginine beta-naphthylamide"> phenylalanine-arginine beta-naphthylamide</a> </p> <a href="https://publications.waset.org/abstracts/85517/the-impact-of-efflux-pump-inhibitor-on-the-activity-of-benzosiloxaboroles-and-benzoxadiboroles-against-gram-negative-rods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85517.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">272</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">301</span> Development of an Atmospheric Radioxenon Detection System for Nuclear Explosion Monitoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Thomas">V.

In this context, the Alternative Energies and French Atomic Energy Commission (CEA) has developed a fixed device to continuously measure the concentration of these fission products, the SPALAX process. During its atmospheric transport, the radioactive xenon will undergo a significant dilution between the source point and the measurement station. Regarding the distance between fixed stations located all over the globe, the typical volume activities measured are near 1 mBq m⁻³. To avoid the constraints induced by atmospheric dilution, the development of a mobile detection system is in progress; this system will allow on-site measurements in order to confirm or infringe a suspicious measurement detected by a fixed station. Furthermore, this system will use beta/gamma coincidence measurement technique in order to drastically reduce environmental background (which masks such activities). The detector prototype consists of a gas cell surrounded by two large silicon wafers, coupled with two square NaI(Tl) detectors. The gas cell has a sample volume of 30 cm³ and the silicon wafers are 500 µm thick with an active surface area of 3600 mm². In order to minimize leakage current, each wafer has been segmented into four independent silicon pixels. This cell is sandwiched between two low background NaI(Tl) detectors (70x70x40 mm³ crystal). The expected Minimal Detectable Concentration (MDC) for each radio-xenon is in the order of 1-10 mBq m⁻³. Three 4-channels digital acquisition modules (Pixie-NET) are used to process all the signals. Time synchronization is ensured by a dedicated PTP-network, using the IEEE 1588 Precision Time Protocol. We would like to present this system from its simulation to the laboratory tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta%2Fgamma%20coincidence%20technique" title="beta/gamma coincidence technique">beta/gamma coincidence technique</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20level%20measurement" title=" low level measurement"> low level measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=radioxenon" title=" radioxenon"> radioxenon</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20pixels" title=" silicon pixels"> silicon pixels</a> </p> <a href="https://publications.waset.org/abstracts/100571/development-of-an-atmospheric-radioxenon-detection-system-for-nuclear-explosion-monitoring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100571.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">126</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">300</span> A Posterior Predictive Model-Based Control Chart for Monitoring Healthcare</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi-Fan%20Lin">Yi-Fan Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20P.%20Howley"> Peter P.

In Australia, the Australian Council on Healthcare Standards records and reports hundreds of clinical indicators (CIs) nationally across the healthcare system. These CIs are measures of performance in the clinical setting, and are used as a screening tool to help assess whether a standard of care is being met. Existing analysis and reporting of these CIs incorporate Bayesian methods to address sampling variation; however, such assessments are retrospective in nature, reporting upon the previous six or twelve months of data. The use of Bayesian methods within statistical process control for monitoring systems is an important pursuit to support more timely decision-making. Our research has developed and assessed a new graphical monitoring tool, similar to a control chart, based on the beta-binomial posterior predictive (BBPP) distribution to facilitate the real-time assessment of health care organizational performance via CIs. The BBPP charts have been compared with the traditional Bernoulli CUSUM (BC) chart by simulation. The more traditional “central” and “highest posterior density” (HPD) interval approaches were each considered to define the limits, and the multiple charts were compared via in-control and out-of-control average run lengths (ARLs), assuming that the parameter representing the underlying CI rate (proportion of cases with an event of interest) required estimation. Preliminary results have identified that the BBPP chart with HPD-based control limits provides better out-of-control run length performance than the central interval-based and BC charts. Further, the BC chart’s performance may be improved by using Bayesian parameter estimation of the underlying CI rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=average%20run%20length%20%28ARL%29" title="average run length (ARL)">average run length (ARL)</a>, <a href="https://publications.waset.org/abstracts/search?q=bernoulli%20cusum%20%28BC%29%20chart" title=" bernoulli cusum (BC) chart"> bernoulli cusum (BC) chart</a>, <a href="https://publications.waset.org/abstracts/search?q=beta%20binomial%20posterior%20predictive%20%28BBPP%29%20distribution" title=" beta binomial posterior predictive (BBPP) distribution"> beta binomial posterior predictive (BBPP) distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20indicator%20%28CI%29" title=" clinical indicator (CI)"> clinical indicator (CI)</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20organization%20%28HCO%29" title=" healthcare organization (HCO)"> healthcare organization (HCO)</a>, <a href="https://publications.waset.org/abstracts/search?q=highest%20posterior%20density%20%28HPD%29%20interval" title=" highest posterior density (HPD) interval"> highest posterior density (HPD) interval</a> </p> <a href="https://publications.waset.org/abstracts/95410/a-posterior-predictive-model-based-control-chart-for-monitoring-healthcare" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95410.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">203</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">299</span> Analogy in Microclimatic Parameters, Chemometric and Phytonutrient Profiles of Cultivated and Wild Ecotypes of Origanum vulgare L., across Kashmir Himalaya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumira%20Jan">Sumira Jan</a>, <a href="https://publications.waset.org/abstracts/search?q=Javid%20Iqbal%20Mir"> Javid Iqbal Mir</a>, <a href="https://publications.waset.org/abstracts/search?q=Desh%20Beer%20Singh"> Desh Beer Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20Sharma"> Anil Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafia%20Zaffar%20Faktoo"> Shafia Zaffar Faktoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aims: Climatic and edaphic factors immensely influence crop quality and proper development. Regardless of economic potential, Himalayan Oregano has not subjected to phytonutrient and chemometric evaluation and its relationship with environmental conditions are scarce. The central objective of this research was to investigate microclimatic variation among wild and cultivated populations located in a microclimatic gradient in north-western Himalaya, Kashmir and analyse if such disparity was related with diverse climatic and edaphic conditions. Methods: Micrometeorological, Atomic absorption spectroscopy for micro elemental analysis was carried for soil. HPLC was carried out to estimate variation in phytonutrients and phytochemicals. Results: Geographic variation in phytonutrient was observed among cultivated and wild populations and among populations diverse within regions. Cultivated populations exhibited comparatively lesser phytonutrient value than wild populations. Moreover, our results observed higher vegetative growth of O. vulgare L. with higher pH (6-7), elevated organic carbon (2.42%), high nitrogen (97.41Kg/ha) and manganese (10-12ppm) and zinc contents (0.39-0.50) produce higher phytonutrients. HPLC data of phytonutrients like quercetin, betacarotene, ascorbic acid, arbutin and catechin revealed direct relationship with UV-B flux (r2=0.82), potassium (r2=0.97) displaying parallel relationship with phytonutrient value. Conclusions: Catechin was found as predominant phytonutrient among all populations with maximum accumulation of 163.8 ppm while as quercetin exhibited lesser value. Maximum arbutin (53.42ppm) and quercetin (2.87ppm) accumulated in plants thriving under intense and high UV-B flux. Minimum variation was demonstrated by beta carotene and ascorbic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytonutrient"
