and its management remained the most complaint of emergency service admission. Diagnostic and therapeutic procedures add to patients’ pain. Diminishing the pain increases the quality of patient’s feeling and improves the patient-physician relationship. Aim: The aim of this study was to evaluate the outcomes and side effects of opioid administration in emergency patients. Material and Methods: patients admitted to ward II emergency service of Imam Khomeini hospital, who received one of the opioids: morphine, pethidine, methadone or fentanyl as an analgesic were evaluated. Their vital signs and general condition were examined before and after drug injection. Also, patient’s pain experience were recorded as numerical rating score (NRS) before and after analgesic administration. Results: 268 patients were studied. 34 patients were addicted to opioid drugs. Morphine had the highest rate of prescription (86.2%), followed by pethidine (8.5%), methadone (3.3%) and fentanyl (1.68). While initial NRS did not show significant difference between addicted patients and non-addicted ones, NRS decline and its score after drug injection were significantly lower in addicted patients. All patients had slight but statistically significant lower respiratory rate, heart rate, blood pressure and O2 saturation. There was no significant difference between different kind of opioid prescription and its outcomes or side effects. Conclusion: Pain management should be always in physicians’ mind during emergency admissions. It should not be assumed that an addicted patient complaining of pain is malingering to receive drug. Titration of drug and close monitoring must be in the curriculum to prevent any hazardous side effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20rating%20score" title="numerical rating score">numerical rating score</a>, <a href="https://publications.waset.org/abstracts/search?q=opioid" title=" opioid"> opioid</a>, <a href="https://publications.waset.org/abstracts/search?q=pain" title=" pain"> pain</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20department" title=" emergency department"> emergency department</a> </p> <a href="https://publications.waset.org/abstracts/18038/opioid-administration-on-patients-hospitalized-in-the-emergency-department" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18038.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">426</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">46</span> Role of Giardia lamblia Infection in the Pathogenesis of Gastritis in Patients with Dyspepsia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aly%20Kassem">Aly Kassem</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20A.%20Sabet"> Eman A.

Concomitant Helecobacter Pylori (H. pylori) and Giardia lamblia infection is common for their similar mode of transmission and strong correlation to socioeconomic levels. Only few reports had described gastric giardiasis. Our aim was to detect H. pylori and Giardia in gastric antral mucosal biopsies from patients with dyspepsia. The impact of both pathogens on clinical, endoscopic and histopathogical changes was studied. Methods: 48 patients with dyspepsia (group1) and 28 control patients (patients undergoing esophagogastroduodenoscopy EGD for reasons other than dyspepsia), (group 2) were studied. Endoscopic data were reported and gastric biopsy specimens were obtained for subsequent PCR assay for both organisms and for histopathological and electron microscopic examination. Results: Endoscopic antral gastritis and duodenal lesions were found in both groups, however, they were significantly more frequently in group 1 (p= 0.002 and P= 0.0005 respectively). Esophageal lesions, nodular antral gastritis, gastric ulcers and superficial corpal gastritis were found only in group 1. PCR detected H. pylori infection in 58% Vs 64 % for group 1 and group 2 respectively (P: NS). Giardia infection was present in 67 % Vs 42 % for group 1 and group 2 respectively (P=0.0003, Odd ratio=2.6). Co-infection with H. pylori and Giardia was present in 33% of group 1 Vs 36% for group 2 (P:NS). Abnormal histologic findings were found in both groups, however, intestinal metaplasia was found in group 1 only. Cellular abnormalities in the form of cytoplasmic vacuoles, mitochondrial destruction or nuclear abnormalities were found by Electron microscopic study in infected subjects of both groups. Conclusion: H. pylori is not the only gastric pathogen in our community, gastric giardiasis is another pathogen. Its contribution might be a factor in persistent dyspepsia after H. pylori eradication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dyspepsia" title="dyspepsia">dyspepsia</a>, <a href="https://publications.waset.org/abstracts/search?q=gastritis" title=" gastritis"> gastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Giardia%20lamblia" title=" Giardia lamblia"> Giardia lamblia</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20pylori" title=" H. pylori "> H. pylori </a> </p> <a href="https://publications.waset.org/abstracts/45386/role-of-giardia-lamblia-infection-in-the-pathogenesis-of-gastritis-in-patients-with-dyspepsia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45386.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">305</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">45</span> Fundamental Natural Frequency of Chromite Composite Floor System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Abbas%20Gandomkar">Farhad Abbas Gandomkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Danesh"> Mona Danesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to determine Fundamental Natural Frequency (FNF) of a structural composite floor system known as Chromite. To achieve this purpose, FNFs of studied panels are determined by development of Finite Element Models (FEMs) in ABAQUS program. American Institute of Steel Construction (AISC) code in Steel Design Guide Series 11, presents a fundamental formula to calculate FNF of a steel framed floor system. This formula has been used to verify results of the FEMs. The variability in the FNF of the studied system under various parameters such as dimensions of floor, boundary conditions, rigidity of main and secondary beams around the floor, thickness of concrete slab, height of composite joists, distance between composite joists, thickness of top and bottom flanges of the open web steel joists, and adding tie beam perpendicular on the composite joists, is determined. The results show that changing in dimensions of the system, its boundary conditions, rigidity of main beam, and also adding tie beam, significant changes the FNF of the system up to 452.9%, 50.8%, -52.2%, %52.6%, respectively. In addition, increasing thickness of concrete slab increases the FNF of the system up to 10.8%. Furthermore, the results demonstrate that variation in rigidity of secondary beam, height of composite joist, and distance between composite joists, and thickness of top and bottom flanges of open web steel joists insignificant changes the FNF of the studied system up to -0.02%, -3%, -6.1%, and 0.96%, respectively. Finally, the results of this study help designer predict occurrence of resonance, comfortableness, and design criteria of the studied system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fundamental%20Natural%20Frequency" title="Fundamental Natural Frequency">Fundamental Natural Frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=Chromite%20Composite%20Floor%20System" title=" Chromite Composite Floor System"> Chromite Composite Floor System</a>, <a href="https://publications.waset.org/abstracts/search?q=Finite%20Element%20Method" title=" Finite Element Method"> Finite Element Method</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20and%20high%20frequency%20floors" title=" low and high frequency floors"> low and high frequency floors</a>, <a href="https://publications.waset.org/abstracts/search?q=Comfortableness" title=" Comfortableness"> Comfortableness</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance." title=" resonance."> resonance.</a> </p> <a href="https://publications.waset.org/abstracts/32885/fundamental-natural-frequency-of-chromite-composite-floor-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32885.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">457</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">44</span> Investigating the Suitability of Utilizing Lyophilized Gels to Improve the Stability of Ufasomes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Hassan%20Aburahma">Mona Hassan Aburahma</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Hamed%20Salama"> Alaa Hamed Salama </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ufasomes “unsaturated fatty acids liposomes” are unique nano-sized self-assembled bilayered vesicles that can be easily created from the readily available unsaturated fatty acid. Ufasomes are formed due to weak associative interaction of the fully ionized and unionized fatty acids into bilayers structures. In the ufasomes constructs, the fatty acid molecules are oriented with their hydrocarbon tails directed toward the membrane interior and the carboxyl groups are in contact with water. Although ufasomes can be employed as a safe vesicular carrier for drugs, the extreme instability of their aqueous dispersions hinders their effective use in drug delivery field. Accordingly, in our study, lyophilized gels containing ufasomes were prepared using a simple assembling technique form the readily available oleic acid to overcome the colloidal instability of the ufasomes dispersions and convert them into accurate unit dosage forms. The influence of changing cholesterol percentage relative to oleic acid on the ufasomes vesicles were investigated using factorial design. The optimized oleic acid ufasomes comprised nanoscaled spherical vesicles. Scanning electron micrographs of the lyophilized gels revealed that the included ufasomes were intact, non-aggregating, and preserved their spherical morphology. Rheological characterization (viscosity and shear stress versus shear rate) of reconstituted ufasomal lyophilized gel ensured the ease of application. The capability of the ufasomes, included in the gel, to penetrate deep through the mucosa layers was illustrated using ex-vivo confocal laser imaging, thereby, highlighting the feasibility of stabilizing ufasomes using lyophilized gel platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ufasomes" title="ufasomes">ufasomes</a>, <a href="https://publications.waset.org/abstracts/search?q=lyophilized%20gel" title=" lyophilized gel"> lyophilized gel</a>, <a href="https://publications.waset.org/abstracts/search?q=confocal%20scanning%20microscopy" title=" confocal scanning microscopy"> confocal scanning microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=rheological%20characterization" title=" rheological characterization"> rheological characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=oleic%20acid" title=" oleic acid "> oleic acid </a> </p> <a href="https://publications.waset.org/abstracts/21763/investigating-the-suitability-of-utilizing-lyophilized-gels-to-improve-the-stability-of-ufasomes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21763.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">408</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">43</span> The Effects of High Velocity Low Amplitude Thrust Manipulation versus Low Velocity Low Amplitude Mobilization in Treatment of Chronic Mechanical Low Back Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20R.%20Z.%20Baghdadi">Ahmed R.

Purpose: This study compared the effects of HVLAT versus LVLA on pain, functional deficits and segmental mobility in treatment of chronic mechanical LBP. Methods: Ninety patients suffering from chronic mechanical LBP are classified to three groups; Thirty patients treated by HVLAT (group I), thirty patients treated by LVLA (group II) and thirty patients as control group (group III) participated in the study. The mean age was 28.00±2.92, 27.83±2.28 and 28.07±3.05 years and BMI 27.98±2.60, 28.80±2.40 and 28.70±2.53 kg/m2 for group I, II and III respectively. The Visual Analogue Scale (VAS), the Oswestry low back pain disability questionnaire and modified schoper test were used for assessment. Assessments were conducted two weeks before and after treatment with the control group being assessed at the same time intervals. The treatment program group one was two weeks single session per week, and for group II two sessions per week for two weeks. Results: The One-way ANOVA revealed that group I had significantly lower pain scores and Oswestry score compared with group II two weeks after treatment. Moreover, the mobility in modified schoper increased significantly and the pain scores and Oswestry scores decreased significantly after treatment in group I and II compared with control group. Interpretation/Conclusion: HVLAT is preferable to LVLA mobilization, possibly due to a beneficial neurophysiological effect by Stimulating mechanically sensitive neurons in the lumbar facet joint capsule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=manipulation" title=" manipulation"> manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=mobilization" title=" mobilization"> mobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20velocity" title=" low velocity"> low velocity</a> </p> <a href="https://publications.waset.org/abstracts/20449/the-effects-of-high-velocity-low-amplitude-thrust-manipulation-versus-low-velocity-low-amplitude-mobilization-in-treatment-of-chronic-mechanical-low-back-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20449.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">602</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">42</span> Predictors of Post-marketing Regulatory Actions Concerning Hepatotoxicity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salwa%20M.%20Almomen">Salwa M.

Unfortunately, serious adverse hepatic effects can occur after marketing with limited indicators during clinical development. Therefore, finding possible predictors for hepatotoxicity might guide the monitoring program of various stakeholders. Methods: We examined the clinical review documents for drugs approved in the US from 2011 to 2016 to evaluate their hepatic safety profile. Predictors: we assessed whether these medications meet Hy’s Law with hepatotoxicity grade ≥ 3, labeled hepatic adverse effects at approval, or accelerated approval status. Outcome: post-marketing regulatory action related to hepatotoxicity, including product withdrawal or updates to warning, precaution, or adverse effects sections. Statistical analysis: drugs were included in the analysis from the time of approval until the end of 2019 or the first post-marketing regulatory action related to hepatotoxicity, whichever occurred first. The hazard ratio (HR) was estimated using Cox-regression analysis. Results: We included 192 medications in the study. We classified 48 drugs as having grade ≥ 3 hepatotoxicities, 43 had accelerated approval status, and 74 had labeled information about hepatotoxicity prior to marketing. The adjusted HRs for post-marketing regulatory action for products with grade ≥ 3 hepatotoxicity was 0.61 (95% confidence interval [CI], 0.17-2.23), 0.92 (95%CI, 0.29-2.93) for a drug approved via accelerated approval program, and was 0.91 (95%CI, 0.33-2.56) for drugs with labeled hepatotoxicity information at approval time.

According to the structure of zolpidem and on the basis of the structure-activity relationship of BZD receptor ligands, six novel derivatives of 2-fluorobenzyloxy 4,6- diphenylpyramidin-2-ol have been synthesized. We studied the hypnotic, sedative, and anticonvulsant effects of the novel compounds. Method: In this study, we used male mice (18 to 25 g). All the substances were injected intraperitoneally. The hypnotic effect of the compounds was examined by pentobarbital induced sleeping test. The locomotor activities and sedative effects of the novel compounds were evaluated by open field and loss of righting reflex test, respectively. The anticonvulsant effects of the novel compounds were assessed by PTZ and MES tests. Results: In the pentobarbital induced sleeping and open field tests, compound 4-(2-((2-fluorobenzyl)oxy)phenyl)-6-(p-tolyl) pyrimidine-2-ol with ED50=14.20 mg/kg and ED50=47.88 mg/kg, respectively, was the most effective compound. None of the novel compounds showed a significant anticonvulsant effect in the PTZ test. In MES test, compound 4-(2-((2-fluorobenzyl)oxy)phenyl)-6-(p-tolyl)pyrimidine-2-ol with ED50=12.92 mg/kg was the most effective compound. Flumazenil blocked the sedation and hypnosis of all the compounds. Conclusion: All of the novel derivatives showed significant sedative-hypnotic activities and caused the reduction of locomotor activities. The results show that the methyl lipophilic substitutes on the phenyl ring of 4,6-diphenylpyramidin-2-ol derivatives can increase the sedative and hypnotic effects of the derivatives. Flumazenil antagonized the sedative, and the hypnotic effects of the compounds indicate that BZD receptors are involved in the effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BZD" title="BZD">BZD</a>, <a href="https://publications.waset.org/abstracts/search?q=sedative" title=" sedative"> sedative</a>, <a href="https://publications.waset.org/abstracts/search?q=hyptonic" title=" hyptonic"> hyptonic</a>, <a href="https://publications.waset.org/abstracts/search?q=anticonvulsant" title=" anticonvulsant"> anticonvulsant</a>, <a href="https://publications.waset.org/abstracts/search?q=zolpidem" title=" zolpidem"> zolpidem</a>, <a href="https://publications.waset.org/abstracts/search?q=MES" title=" MES"> MES</a>, <a href="https://publications.waset.org/abstracts/search?q=PTZ" title=" PTZ"> PTZ</a>, <a href="https://publications.waset.org/abstracts/search?q=benzodiazepine" title=" benzodiazepine"> benzodiazepine</a>, <a href="https://publications.waset.org/abstracts/search?q=locomotor%20activities" title=" locomotor activities"> locomotor activities</a>, <a href="https://publications.waset.org/abstracts/search?q=pentobarbital%20induced%20sleeping%20tests" title=" pentobarbital induced sleeping tests"> pentobarbital induced sleeping tests</a> </p> <a href="https://publications.waset.org/abstracts/141043/evaluation-of-anticonvulsant-and-sedative-hypnotic-activities-of-novel-2-fluorobenzyloxy-46-diphenylpyrimidin-2-ol-derivatives-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141043.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">64</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">40</span> p210 BCR-ABL1 CML with CMML Clones: A Rare Presentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Vijayaran">Mona Vijayaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurleen%20Oberoi"> Gurleen Oberoi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Mishra"> Sanjay Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: p190 BCR‐ABL1 in CML is often associated with monocytosis. In the case described here, monocytosis is associated with coexisting p210 BCR‐ABL and CMML clones. Mutation analysis using next‐generation sequence (NGS) in our case showed TET2 and SRSF2 mutations. Aims & Objectives: A 75-year male was evaluated for monocytosis and thrombocytopenia. CBC showed Hb-11.8g/dl, TLC-12,060/cmm, Monocytes-35%, Platelets-39,000/cmm. Materials & Methods: Bone marrow examination showed a hypercellular marrow with myeloid series showing sequential maturation up to neutrophils with 30% monocytes. Immunophenotyping by flow cytometry from bone marrow had 3% blasts. Making chronic myelomonocytic leukemia as the likely diagnosis. NGS for myeloid mutation panel had TET2 (48.9%) and SRSF2 (32.5%) mutations. This report further supported the diagnosis of CMML. To fulfil the WHO diagnostic criteria for CMML, a BCR ABL1 by RQ-PCR was sent. The report came positive for p210 (B3A2, B2A2) Major Transcript (M-BCR) % IS of 38.418. Result: The patient was counselled regarding the unique presentation of the presence of 2 clones- P210 CML and CMML. After discussion with an international faculty with vast experience in CMML. It was decided to start this elderly gentleman on Imatinib 200mg and not on azacytidine, as ASXL1 was not present; hence, his chances of progressing to AML would be less and on the other end, if CML is left untreated then chances of progression to blast phase would always be a possibility. After 3 months on Imatinib his platelet count improved to 80,000 to 90,000/cmm, but his monocytosis persists. His 3rd month BCR-ABL1 IS% is 0.004%. Conclusion: After searching the literature, there were no case reports of a coexisting CML p210 with CMML. This case might be the first case report. p190 BCR ABL1 is often associated with monocytosis. There are few case reports of p210 BCR ABL1 positivity in patients with monocytosis but none with coexisting CMML. This case highlights the need for extensively evaluating patients with monocytosis with next-generation sequencing for myeloid mutation panel and BCR-ABL1 by RT-PCR to correctly diagnose and treat them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CMML" title="CMML">CMML</a>, <a href="https://publications.waset.org/abstracts/search?q=NGS" title=" NGS"> NGS</a>, <a href="https://publications.waset.org/abstracts/search?q=p190%20CML" title=" p190 CML"> p190 CML</a>, <a href="https://publications.waset.org/abstracts/search?q=Imatinib" title=" Imatinib"> Imatinib</a> </p> <a href="https://publications.waset.org/abstracts/159896/p210-bcr-abl1-cml-with-cmml-clones-a-rare-presentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159896.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">77</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">39</span> Egyptian Soil Isolate Shows Promise as a Source of a New Broad-spectrum Antimicrobial Agent Against Multidrug-resistant Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norhan%20H.%20Mahdally">Norhan H.

The exhaustion of the current antibiotic arsenal and the scarcity of new antimicrobials in the pipeline aggravate this threat and necessitate a prompt and effective response. This study focused on two major pathogens that can cause serious infections: carbapenem-resistant Acinetobacter baumannii (CRAB) and methicillin-resistant Staphylococcus aureus (MRSA). Multiple soil isolates were collected from several locations throughout Egypt and screened for their conventional and non-conventional antimicrobial activities against MDR pathogens. One isolate exhibited potent antimicrobial activity and was subjected to multiple rounds of fractionation. After fermentation and bio-guided fractionation, we identified pure microbial secondary metabolites with two scaffolds that exhibited promising effects against CRAB and MRSA. Scaling up and chemical synthesis of derivatives of the identified metabolite resulted in obtaining a more potent derivative, which we designated as 2HP. Cytotoxicity studies indicated that 2HP is well-tolerated by human cells. Ongoing work is focusing on formulating the new compound into a nano-formulation to enhance its delivery. Also, to have a better idea about how this compound works, a proteomic approach is currently underway. Our findings suggest that 2HP is a potential new broad-spectrum antimicrobial agent. Further studies are needed to confirm these findings and to develop 2HP into a safe and effective treatment for MDR infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broad-spectrum%20antimicrobials" title="broad-spectrum antimicrobials">broad-spectrum antimicrobials</a>, <a href="https://publications.waset.org/abstracts/search?q=carbapenem-resistant%20acinetobacter%20baumannii" title=" carbapenem-resistant acinetobacter baumannii"> carbapenem-resistant acinetobacter baumannii</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20discovery" title=" drug discovery"> drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=methicillin-resistant%20staphylococcus%20aureus" title=" methicillin-resistant staphylococcus aureus"> methicillin-resistant staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug-resistant" title=" multidrug-resistant"> multidrug-resistant</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20products" title=" natural products"> natural products</a> </p> <a href="https://publications.waset.org/abstracts/170540/egyptian-soil-isolate-shows-promise-as-a-source-of-a-new-broad-spectrum-antimicrobial-agent-against-multidrug-resistant-pathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170540.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">80</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">38</span> The Effect of Tooth Brushing with Whitening and Non-Whitening Tooth Paste on Surface Roughness of Coated and Uncoated Glass Ionomer Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hidayati">Hidayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Eni%20Rahmi"> Eni Rahmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Deli%20Mona"> Deli Mona</a>, <a href="https://publications.waset.org/abstracts/search?q=Cytha%20Nilam%20Chairani"> Cytha Nilam Chairani</a>, <a href="https://publications.waset.org/abstracts/search?q=Aulina%20Refri%20Rahmi"> Aulina Refri Rahmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Restoration materials could undergo changes in their clinical properties such as changes in roughness of the restoration's surface. An increase of surface roughness accelerates bacterial colonization and plaque maturation. It can be prevented by mechanically clean the tooth surface by brushing the teeth using toothpaste. Toothpaste may contain abrasives materials that usually found in whitening toothpaste. Those abrasive materials could increase the roughness of the restoration`s surface. Glass ionomer cement (GIC) is one of the restorative material widely used to this day. GC America has made an innovation called EQUIA to improve their wear resistance by coating the surface of GIC using G-Coat Plus. Objective: To determine the effect of teeth was brushing with whitening and non-whitening toothpaste to the surface roughness of coated and uncoated restoration (GIC). Methods: This research was a laboratory experimental with pretest-posttest group design. There were 28 samples which were divided into 2 groups. The first group was brushed with whitening toothpaste and the second group was brushed with non-whitening toothpaste. Each group was divided into group which coated by G-Coat Plus and group which left uncoated. The value of surface roughness was measured by using Roughness Tester. The data was analyzed by using independent t-test to determine differences between the surface roughness of coated samples and uncoated samples brushed with whitening and non-whitening toothpaste. Result: It was found that average roughness differences before and after being brushed by whitening toothpaste were smaller in coated samples than in uncoated samples (0.07 ± 0.09 < 0.12 ± 0.02). Similar results were also found in samples brushed by non-whitening toothpaste (0.02 ± 0.01 0.03 ± 0.01). The differences of average roughness in samples brushed with non-whitening toothpaste were smaller than samples brushed with whitening toothpaste. Conclusion: The data showed there were statistically significant differences between the surface roughness of coated samples and uncoated samples brushed with non-whitening toothpaste (p < 0.05) but the was no statistically significant to samples brushed with whitening toothpaste (p > 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title="surface roughness">surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=toothpaste" title=" toothpaste"> toothpaste</a>, <a href="https://publications.waset.org/abstracts/search?q=EQUIA" title=" EQUIA"> EQUIA</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a> </p> <a href="https://publications.waset.org/abstracts/66444/the-effect-of-tooth-brushing-with-whitening-and-non-whitening-tooth-paste-on-surface-roughness-of-coated-and-uncoated-glass-ionomer-cement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66444.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">247</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">37</span> Long-Term Follow-Up of Dynamic Balance, Pain and Functional Performance in Cruciate Retaining, Posterior Stabilized Total Knee Arthroplasty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20R.%20Z.%20Baghdadi">Ahmed R.

Yet, a controversy still persists on the appropriate operative technique that doesn’t affect proprioception much. Purpose: This study compared the effects of Cruciate Retaining (CR) and Posterior Stabilized (PS) total knee arthroplasty (TKA on dynamic balance, pain and functional performance following rehabilitation. Methods: Thirty patients with CRTKA (group I), thirty with PSTKA (group II) and fifteen indicated for arthroplasty but weren’t operated on yet (group III) participated in the study. The mean age was 54.53±3.44, 55.13±3.48 and 55.33±2.32 years and BMI 35.7±3.03, 35.7±1.99 and 35.73±1.03 kg/m2 for group I, II, and III respectively. The Berg Balance Scale (BBS), WOMAC pain subscale and Timed-Up-and-Go (TUG) and Stair-Climbing (SC) tests were used for assessment. Assessments were conducted four weeks pre- and post-operatively, three, six and twelve months post-operatively with the control group being assessed at the same time intervals. The post-operative rehabilitation involved hospitalization (1st week), home-based (2nd-4th weeks), and outpatient clinic (5th-12th weeks) programs, follow-up to all groups for twelve months. Results: The Mixed design MANOVA revealed that group I had significantly lower pain scores and SC time compared with group II three, six and twelve months post-operatively. Moreover, the BBS scores increased significantly and the pain scores and TUG and SC time decreased significantly six months post-operatively compared with four weeks pre- and post-operatively and three months post-operatively in group I and II with the opposite being true four weeks post-operatively. But no significant differences in BBS scores, pain scores and TUG and SC time between six and twelve months post-operatively in group I and II. Interpretation/Conclusion: CRTKA is preferable to PSTKA, possibly due to the preserved human proprioceptors in the un-excised PCL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20balance" title="dynamic balance">dynamic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20performance" title=" functional performance"> functional performance</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20arthroplasty" title=" knee arthroplasty"> knee arthroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term" title=" long-term"> long-term</a> </p> <a href="https://publications.waset.org/abstracts/18917/long-term-follow-up-of-dynamic-balance-pain-and-functional-performance-in-cruciate-retaining-posterior-stabilized-total-knee-arthroplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18917.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">411</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">36</span> Adolescent Sleep Hygiene Scale and Adolescent Sleep Wake Scale: Factorial Analysis and Validation for Indian Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sataroopa%20Mishra">Sataroopa Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Basker"> Mona Basker</a>, <a href="https://publications.waset.org/abstracts/search?q=Sneha%20Varkki"> Sneha Varkki</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%20Kumar%20Pandian"> Ram Kumar Pandian</a>, <a href="https://publications.waset.org/abstracts/search?q=Grace%20Rebekah"> Grace Rebekah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sleep deprivation is a matter of public health importance among adolescents. We used adolescent sleep wake scale and adolescent sleep hygiene scale to determine the sleep quality and sleep hygiene respectively of school going adolescents in Vellore city of India. The objective of the study was to do factorial analysis of the scales and validate it for use in local population. Methods: Observational questionnaire based cross sectional study. Setting: Community based school survey in a semi-urban setting in three schools in Vellore city. Data collection: Non probability sample was collected form students studying in standard 9 and 11. Students filled Adolescent Sleep Wake scale (ASWS) and Adolescent Sleep Hygiene Scale (ASHS) translated into vernacular language. Data Analysis: Exploratory Factorial Analysis was used to see the factor loading of various components of the two scales. Confirmatory factorial analysis is subsequently planned for assessing the internal validity of the scales.Results: 557 adolescents were included in the study of 12 – 17 years old. Exploratory factorial analysis of adolescent sleep hygiene scale indicated significant factor loading for 18 items from 28 items originally devised by the authors and has been reconstructed to four domains instead of 9 domains in the original scale namely sleep stability, cognitive – emotional, Physiological - bed time routine - behavioural arousal factor (activites before bedtime and during bed time), Sleep environment (lighting and bed sharing). Factorial analysis of Adolescent sleep wake scale showed factor loading of 18 items out of 28 items in original scale reconstructed into 5 aspects of sleep quality. Conclusions: The factorial analysis gives a reconstructed scale useful for the local population. Further a confirmatory factorial analysis has been subsequently planned to determine the internal consistency of the scale for local population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factorial%20analysis" title="factorial analysis">factorial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20hygiene" title=" sleep hygiene"> sleep hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20quality" title=" sleep quality"> sleep quality</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescent%20sleep%20scale" title=" adolescent sleep scale"> adolescent sleep scale</a> </p> <a href="https://publications.waset.org/abstracts/78064/adolescent-sleep-hygiene-scale-and-adolescent-sleep-wake-scale-factorial-analysis-and-validation-for-indian-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78064.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Stakeholders Perspectives on the Social Determinants of Health and Quality of Life in Aseer Healthy Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Metrek%20Almetrek">Metrek Almetrek</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Alqahtani"> Naser Alqahtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Eisa%20Ghazwani"> Eisa Ghazwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Asiri"> Mona Asiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Alqahtani"> Mohammed Alqahtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Magboolah%20Balobaid"> Magboolah Balobaid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Advocacy of potential for community coalitions to positively address social determinants of health and quality of life, little is known about the views of stakeholders involved in such efforts. This study sought to assess the provinces leaders’ perspectives about social determinants related to the Health Neighborhood Initiative (HNI), a new county effort to support community coalitions. Method and Subjects: We used a descriptive, qualitative study using personal interviews in 2022. We conducted it in the community coalition's “main cities committees” set across service planning areas that serve vulnerable groups located in the seven registered healthy cities to WHO (Abha, Tareeb, Muhayel, Balqarn, Alharajah, Alamwah, and Bisha). We conducted key informant interviews with 76 governmental, profit, non-profit, and community leaders to understand their perspectives about the HNI. As part of a larger project, this study focused on leaders’ views about social determinants of health related to the HNI. All interviews were audio-recorded and transcribed. An inductive approach to coding was used, with text segments grouped by social determinant categories. Results: Provinces leaders described multiple social determinants of health and quality of life that were relevant to the HNI community coalitions: housing and safety, community violence, economic stability, city services coordination and employment and education. Leaders discussed how social determinants were interconnected with each other and the need for efforts to address multiple social determinants simultaneously to effectively improve health and quality of life. Conclusions: Community coalitions have an opportunity to address multiple social determinants of health and quality of life to meet the social needs of vulnerable groups. Future research should examine how community coalitions, like those in the HNI, can actively engage with community members to identify needs and then deliver evidence-based care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20determinants" title="social determinants">social determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20and%20quality%20of%20life" title=" health and quality of life"> health and quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerable%20groups" title=" vulnerable groups"> vulnerable groups</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a> </p> <a href="https://publications.waset.org/abstracts/160309/stakeholders-perspectives-on-the-social-determinants-of-health-and-quality-of-life-in-aseer-healthy-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160309.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">84</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">34</span> Preparation and in vivo Assessment of Nystatin-Loaded Solid Lipid Nanoparticles for Topical Delivery against Cutaneous Candidiasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rawia%20M.%20Khalil">Rawia M.

Our work deals with the preparation of nystatin loaded solid lipid nanoparticles (NystSLNs) using the hot homogenization and ultrasonication method. The prepared NystSLNs were characterized in terms of entrapment efficiency, particle size, zeta potential, transmission electron microscopy, differential scanning calorimetry, rheological behavior and in vitro drug release. A stability study for 6 months was performed. A microbiological study was conducted in male rats infected with Candida albicans, by counting the colonies and examining the histopathological changes induced on the skin of infected rats. The results showed that SLNs dispersions are spherical in shape with particle size ranging from 83.26±11.33 to 955.04±1.09 nm. The entrapment efficiencies are ranging from 19.73±1.21 to 72.46±0.66% with zeta potential ranging from -18.9 to -38.8 mV and shear-thinning rheological Behavior. The stability studies done for 6 months showed that nystatin (Nyst) is a good candidate for topical SLN formulations. A least number of colony forming unit/ ml (cfu/ml) was recorded for the selected NystSLN compared to the drug solution and the commercial Nystatin® cream present in the market. It can be fulfilled from this work that SLNs provide a good skin targeting effect and may represent promising carrier for topical delivery of Nyst offering the sustained release and maintaining the localized effect, resulting in an effective treatment of cutaneous fungal infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=candida%20infections" title="candida infections">candida infections</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20homogenization" title=" hot homogenization"> hot homogenization</a>, <a href="https://publications.waset.org/abstracts/search?q=nystatin" title=" nystatin"> nystatin</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20lipid%20nanoparticles" title=" solid lipid nanoparticles"> solid lipid nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=topical%20delivery" title=" topical delivery"> topical delivery</a> </p> <a href="https://publications.waset.org/abstracts/3539/preparation-and-in-vivo-assessment-of-nystatin-loaded-solid-lipid-nanoparticles-for-topical-delivery-against-cutaneous-candidiasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3539.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">393</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">33</span> X-Ray Crystallographic Studies on BPSL2418 from Burkholderia pseudomallei</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Alharbi">Mona Alharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Melioidosis has emerged as a lethal disease. Unfortunately, the molecular mechanisms of virulence and pathogenicity of Burkholderia pseudomallei remain unknown. However, proteomics research has selected putative targets in B. pseudomallei that might play roles in the B. pseudomallei virulence. BPSL 2418 putative protein has been predicted as a free methionine sulfoxide reductase and interestingly there is a link between the level of the methionine sulfoxide in pathogen tissues and its virulence. Therefore in this work, we describe the cloning expression, purification, and crystallization of BPSL 2418 and the solution of its 3D structure using X-ray crystallography. Also, we aimed to identify the substrate binding and reduced forms of the enzyme to understand the role of BPSL 2418. The gene encoding BPSL2418 from B. pseudomallei was amplified by PCR and reclone in pETBlue-1 vector and transformed into E. coli Tuner DE3 pLacI. BPSL2418 was overexpressed using E. coli Tuner DE3 pLacI and induced by 300μM IPTG for 4h at 37°C. Then BPS2418 purified to better than 95% purity. The pure BPSL2418 was crystallized with PEG 4000 and PEG 6000 as precipitants in several conditions. Diffraction data were collected to 1.2Å resolution. The crystals belonged to space group P2 21 21 with unit-cell parameters a = 42.24Å, b = 53.48Å, c = 60.54Å, α=γ=β= 90Å. The BPSL2418 binding MES was solved by molecular replacement with the known structure 3ksf using PHASER program. The structure is composed of six antiparallel β-strands and four α-helices and two loops. BPSL2418 shows high homology with the GAF domain fRMsrs enzymes which suggest that BPSL2418 might act as methionine sulfoxide reductase. The amino acids alignment between the fRmsrs including BPSL 2418 shows that the three cysteines that thought to catalyze the reduction are fully conserved. BPSL 2418 contains the three conserved cysteines (Cys⁷⁵, Cys⁸⁵ and Cys¹⁰⁹). The active site contains the six antiparallel β-strands and two loops where the disulfide bond formed between Cys⁷⁵ and Cys¹⁰⁹. X-ray structure of free methionine sulfoxide binding and native forms of BPSL2418 were solved to increase the understanding of the BPSL2418 catalytic mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-Ray%20Crystallography" title="X-Ray Crystallography">X-Ray Crystallography</a>, <a href="https://publications.waset.org/abstracts/search?q=BPSL2418" title=" BPSL2418"> BPSL2418</a>, <a href="https://publications.waset.org/abstracts/search?q=Burkholderia%20pseudomallei" title=" Burkholderia pseudomallei"> Burkholderia pseudomallei</a>, <a href="https://publications.waset.org/abstracts/search?q=Melioidosis" title=" Melioidosis"> Melioidosis</a> </p> <a href="https://publications.waset.org/abstracts/54364/x-ray-crystallographic-studies-on-bpsl2418-from-burkholderia-pseudomallei" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54364.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Pleomorphic Dermal Sarcoma: A Management Challenge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Nada">Mona Nada</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahmy%20Fahmy"> Fahmy Fahmy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Pleomorphic dermal sarcoma is a rare form of skin cancer affecting cutaneous layer and, in some cases associated with recurrence and metastasis, very commonly to seen in elderly patient affecting the area of head and neck. Pleomorphic dermal sarcoma rises in ultraviolet light exposed areas. The symptoms and severity of this kind of skin cancer varies according to histological factors. The differentiation of Pleomorphic dermal sarcoma needs extensive immunohistochemistry, as the diagnosis depends mainly on exclusion to rule out other malignancy like poorly differentiated squamous cell carcinoma, melanoma, angiosarcoma and leiomyosarcoma. Objective: assessing the management of Pleomorphic dermal sarcoma in our unit and compared to the updated guidelines. Design: Retrospective study Collection of patient data from medical records at countess of Chester plastic surgery unit of the last 5 years, all histologically confirmed Pleomorphic dermal sarcoma (2017-2023). Data were collected confirmed to be Pleomorphic dermal sarcoma were included in the study. The data collected: clinical description of the lesions at first presentation, operation time, multidisciplinary team discussion, plan, referral as well as second operation and investigation done. With comparison of histological examination, immunohistochemistry staining, the excision and rate of recurrence. Results: data collected N19 from (2017-2023) showed the disease predominantly affecting males and the lesion mainly in head and neck, the diagnosis needed extensive immunohistochemistry to differentiate between other malignancy. recurrence present in numbers of the cases which managed after multidisciplinary team discussion either by excision or radiotherapy. Conclusion: Pleomorphic dermal sarcoma is a rare malignancy which needs more understanding and avoid missing as it is aggressive form of skin cancer, there is a chance of metastasis and recurrence which makes it very important to understand the process of development of the cancer and frequent review of the management guidelines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pleomorphic%20dermal%20sarcoma" title="pleomorphic dermal sarcoma">pleomorphic dermal sarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrence" title=" recurrence"> recurrence</a>, <a href="https://publications.waset.org/abstracts/search?q=radiotherapy" title=" radiotherapy"> radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical" title=" surgical"> surgical</a> </p> <a href="https://publications.waset.org/abstracts/171289/pleomorphic-dermal-sarcoma-a-management-challenge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171289.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">72</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">31</span> Molecular Diversity of Forensically Relevant Insects from the Cadavers of Lahore</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sundus%20Mona">Sundus Mona</a>, <a href="https://publications.waset.org/abstracts/search?q=Atif%20Adnan"> Atif Adnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Babar%20Ali"> Babar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Fareeha%20Arshad"> Fareeha Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Allah%20Rakha"> Allah Rakha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Molecular diversity is the variation in the abundance of species. Forensic entomology is a neglected field in Pakistan. Insects collected from the crime scene should be handled by forensic entomologists who are currently virtually non-existent in Pakistan. Correct identification of insect specimen along with knowledge of their biodiversity can aid in solving many problems related to complicated forensic cases. Inadequate morphological identification and insufficient thermal biological studies limit the entomological utility in Forensic Medicine. Recently molecular identification of entomological evidence has gained attention globally. DNA barcoding is the latest and established method for species identification. Only proper identification can provide a precise estimation of postmortem intervals. Arthropods are known to be the first tourists scavenging on decomposing dead matter. The objective of the proposed study was to identify species by molecular techniques and analyze their phylogenetic importance with barcoded necrophagous insect species of early succession on human cadavers. Based upon this identification, the study outcomes will be the utilization of established DNA bar codes to identify carrion feeding insect species for concordant estimation of post mortem interval. A molecular identification method involving sequencing of a 658bp ‘barcode’ fragment of the mitochondrial cytochrome oxidase subunit 1 (CO1) gene from collected specimens of unknown dipteral species from cadavers of Lahore was evaluated. Nucleotide sequence divergences were calculated using MEGA 7 and Arlequin, and a neighbor-joining phylogenetic tree was generated. Three species were identified, Chrysomya megacephala, Chrysomya saffranea, and Chrysomya rufifacies with low genetic diversity. The fixation index was 0.83992 that suggests a need for further studies to identify and classify forensically relevant insects in Pakistan. There is an exigency demand for further research especially when immature forms of arthropods are recovered from the crime scene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molecular%20diversity" title="molecular diversity">molecular diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20barcoding" title=" DNA barcoding"> DNA barcoding</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20identification" title=" species identification"> species identification</a>, <a href="https://publications.waset.org/abstracts/search?q=forensically%20relevant" title=" forensically relevant"> forensically relevant</a> </p> <a href="https://publications.waset.org/abstracts/114178/molecular-diversity-of-forensically-relevant-insects-from-the-cadavers-of-lahore" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114178.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">149</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">30</span> The Impact of Animal-Assisted Pedagogy on Social Participation in Heterogenous Classrooms: A Survey Considering the Pupils Perspective on Animal-Assisted Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Maria%20Mombeck">Mona Maria Mombeck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social participation in heterogeneous classrooms is one of the main goals in inclusive education. Children with special educational needs (SEN) and children with learning difficulties, or behavioural problems not diagnosed as SEN, are more likely to be excluded by other children than others. It is proven that the presence of dogs, as well as contact with dogs, increases the likelihood of positive social behaviour between humans. Therefore, animal-assisted pedagogy may be presumed to be a constructive way of inclusive teaching and facing the challenges of social inclusion in school classes. This study investigates the presence of a friendly dog in heterogeneous groups of pupils in order to evaluate the influence of dogs on facets of social participation of children in school. 30 German pupils, aged from 10 to 14, in four classes were questioned about their social participation before and after they were educated for a year in school with animal-assisted-pedagogy, using the problem-concerned interview method. In addition, the post-interview includes some general questions about the putative differences or similarities of being educated with and without a dog. The interviews were analysed with the qualitative-content-analysis using QDA software. The results showed that a dog has a positive impact on the atmosphere, student relationships, and well-being in class. Regarding the atmosphere, the pupils mainly argued that the improvement was caused by taking into account the dog’s well-being, respecting the dog-related rules, and by emotional self-regulation. It can be supposed that children regard the rules concerning the dog as more relevant to them than rules, not concerning the dog even if they require the same behaviour and goal. Furthermore, a dog has a positive impact on emotional self-regulation and, therefore, on pupil’s behaviour in class and the atmosphere. In terms of the statements about relationships, the dog’s presence was mainly seen to provide both a unifying aim and a uniting topic to talk about. The improved well-being was described as a feeling of joy and peace of mind. Moreover, the teacher was evaluated as more friendly and trustworthy after animal-assisted teaching. Nevertheless, animal-assisted pedagogy can, rarely, cause problems as well, such as jealousy, distraction, or concerns about the well-being of the dog. The study could prove the relevance of animal-assisted pedagogy for facing the challenges of social participation in inclusive education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal-assisted-pedagogy" title="animal-assisted-pedagogy">animal-assisted-pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusive%20education" title=" inclusive education"> inclusive education</a>, <a href="https://publications.waset.org/abstracts/search?q=human-animal-interactions" title=" human-animal-interactions"> human-animal-interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20participation" title=" social participation"> social participation</a> </p> <a href="https://publications.waset.org/abstracts/115564/the-impact-of-animal-assisted-pedagogy-on-social-participation-in-heterogenous-classrooms-a-survey-considering-the-pupils-perspective-on-animal-assisted-teaching" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115564.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">115</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">29</span> A Normalized Non-Stationary Wavelet Based Analysis Approach for a Computer Assisted Classification of Laryngoscopic High-Speed Video Recordings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20K.%20Fehling">Mona K.

Consequently, the visual examination of vocal fold vibrations is an integral part within the clinical diagnostic process. For an objective analysis of the vocal fold vibration patterns, the two-dimensional vocal fold dynamics are captured during sustained phonation using an endoscopic high-speed camera. In this work, we present an approach allowing a fully automatic analysis of the high-speed video data including a computerized classification of healthy and pathological voices. The approach bases on a wavelet-based analysis of so-called phonovibrograms (PVG), which are extracted from the high-speed videos and comprise the entire two-dimensional vibration pattern of each vocal fold individually. Using a principal component analysis (PCA) strategy a low-dimensional feature set is computed from each phonovibrogram. From the PCA-space clinically relevant measures can be derived that quantify objectively vibration abnormalities. In the first part of the work it will be shown that, using a machine learning approach, the derived measures are suitable to distinguish automatically between healthy and pathological voices. Within the approach the formation of the PCA-space and consequently the extracted quantitative measures depend on the clinical data, which were used to compute the principle components. Therefore, in the second part of the work we proposed a strategy to achieve a normalization of the PCA-space by registering the PCA-space to a coordinate system using a set of synthetically generated vibration patterns. The results show that owing to the normalization step potential ambiguousness of the parameter space can be eliminated. The normalization further allows a direct comparison of research results, which bases on PCA-spaces obtained from different clinical subjects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wavelet-based%20analysis" title="Wavelet-based analysis">Wavelet-based analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Multiscale%20product" title=" Multiscale product"> Multiscale product</a>, <a href="https://publications.waset.org/abstracts/search?q=normalization" title=" normalization"> normalization</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20assisted%20classification" title=" computer assisted classification"> computer assisted classification</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20laryngoscopy" title=" high-speed laryngoscopy"> high-speed laryngoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=vocal%20fold%20analysis" title=" vocal fold analysis"> vocal fold analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=phonovibrogram" title=" phonovibrogram"> phonovibrogram</a> </p> <a href="https://publications.waset.org/abstracts/51843/a-normalized-non-stationary-wavelet-based-analysis-approach-for-a-computer-assisted-classification-of-laryngoscopic-high-speed-video-recordings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51843.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Influence of Strengthening of Hip Abductors and External Rotators in Treatment of Patellofemoral Pain Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karima%20Abdel%20Aty%20Hassan%20Mohamed">Karima Abdel Aty Hassan Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20Mohamed%20Ismail"> Manal Mohamed Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Hassan%20Gamal%20Eldein"> Mona Hassan Gamal Eldein</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hassan%20Hussein"> Ahmed Hassan Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Aziz%20Mohamed%20Elsingerg"> Abdel Aziz Mohamed Elsingerg </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Patellofemoral pain (PFP) is a common musculoskeletal pain condition, especially in females. Decreased hip muscle strength has been implicated as a contributing factor, yet the relationships between pain, hip muscle strength and function are not known. Objective: The purpose of this study is to investigate the effects of strengthening hip abductors and lateral rotators on pain intensity, function and hip abductor and hip lateral rotator eccentric and concentric torques in patients with PFPS. Methods: Thirty patients had participated in this study; they were assigned into two experimental groups. With age ranged for eighty to thirty five years. Group A consisted of 15 patients (11females and 4 males) with mean age 20.8 (±2.73) years, received closed kinetic chain exercises program, stretching exercises for tight lower extremity soft tissues, and hip strengthening exercises .Group B consisted of 15 patients (12 females and 3 males) with mean age 21.2(±3.27) years, received closed kinetic chain exercises program and stretching exercises for tight lower extremity soft tissues. Treatment was given 2-3times/week, for 6 weeks. Patients were evaluated pre and post treatment for their pain severity, function of knee joint, hip abductors and external rotators concentric/eccentric peak torque. Result: the results revealed that there were significant differences in pain and function between both groups, while there was improvement for all values for both group. Conclusion: Six weeks rehabilitation program focusing on knee strengthening exercises either supplemented by hip strengthening exercises or not effective in improving function, reducing pain and improving hip muscles torque in patients with PFPS. However, adding hip abduction and lateral rotation strengthening exercises seem to reduce pain and improve function more efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patellofemoral%20pain%20syndrome" title="patellofemoral pain syndrome">patellofemoral pain syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20muscles" title=" hip muscles"> hip muscles</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=isokinetic" title=" isokinetic "> isokinetic </a> </p> <a href="https://publications.waset.org/abstracts/23022/influence-of-strengthening-of-hip-abductors-and-external-rotators-in-treatment-of-patellofemoral-pain-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23022.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">447</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">27</span> Influence of Applied Inorganic and Organic Nitrogen Fertilizers on Nitrogen Forms in Biochar-Treated Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20H.%20El-Gamal">Eman H.

The incubation course was extended to 144 days at 30 ± 3 ℃ and at 50% of soil water holding capacity (WHC). Two types of biochars were obtained by pyrolysis at 500 ℃ from rice husk (RHB) and sugarcane bagasse (SCBB). The experiment was planned in a factorial experimental design with three factors (6 periods '24 days for each period' × 3 biochar types 'un-amended, RHB and SCBB' × 3 nitrogen fertilizers 'control, ammonium nitrate; AN and animal manure; AM') in a completely randomized design. The results obtained showed that the highest level of TN was found in the first 24 days of the incubation period in all treatments. However, the amount of TN was decreased with proceeding incubation period up to 144 days and reached to the lowest level at the end of incubation with values of change rate was 17.5, 16.6, and 14.6 g kg⁻¹ day⁻¹ for the un-amended, RHB and SCBB treated soil, respectively. The values of change rate in biochar-soils treated with nitrogen fertilizers were decreased gradually through the whole incubation time from 127.22 to 12.45 g kg⁻¹ day⁻¹ and from 65.00 to 13.43 g kg⁻¹ day⁻¹ for AN and AM respectively, in the case of RHB-soil. While in SCBB-soil, these values were decreased from 70.83 to 12.13 g kg⁻¹ day⁻¹ and from 59.17 to 11.48 g kg⁻¹ day⁻¹ for AN and AM treatments, respectively. The lowest concentration of exchangeable NH₄⁺ was generally found through the period from 24-48 days of incubation. However, the addition of nitrogen fertilizers, enhanced NH₄⁺ production through incubation periods. In the case of RHB-soil, the value of change rate in NH₄⁺ level in the first 24 days of incubation was 0.43 mg kg⁻¹ day⁻¹ and with the addition of AN and AM this value increased to 1.54 and 4.38 mg kg⁻¹ day⁻¹, respectively. In the case of SCBB-soil, the value of change rate in NH₄⁺ level was 0.29 mg kg⁻¹ day⁻¹ which increased to 1.04 mg kg⁻¹ day⁻¹ at the end of incubation, and due to the addition of AN and AM this value increased to 2.78 and 1.90 mg kg⁻¹ day⁻¹ in the first 24 days of incubation period, respectively. However, as compared to the control treatment, the lowest rate of change in NH₄⁺ level was found at the end of incubation. On the other hand, incubation of all biochars-amended soil and treated with AN and AM decreased the concentration levels of NO₃⁻, especially through the first 24-72 days of incubation period. As a result, the values of change rate in NO₃⁻ concentrations in all treatments were almost negative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonium%20nitrate" title="ammonium nitrate">ammonium nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20manure" title=" animal manure"> animal manure</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20husk" title=" rice husk"> rice husk</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane%20bagasse" title=" sugarcane bagasse"> sugarcane bagasse</a> </p> <a href="https://publications.waset.org/abstracts/103277/influence-of-applied-inorganic-and-organic-nitrogen-fertilizers-on-nitrogen-forms-in-biochar-treated-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103277.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">133</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">26</span> Proniosomes as a Carrier for Ocular Drug Delivery </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rawia%20M.%20Khalil">Rawia M.

Conjunctivitis is an inflammation of the conjunctiva, due to Staphylococcus aureus. Lomefloxacin HCl (LXN) is a third generation flouroquinolone antibiotic with a broad spectrum against wide range of bacteria and very effective against Staph infections especially in conjunctiva (conjunctivitis). The present study aims to develop and evaluate novel ocular proniosomal gels of Lomefloxacin Hcl (LXN); in order to improve its ocular bioavailability for the management of bacterial conjunctivitis. Materials and methods: Proniosomes were prepared by coacervation phase separation method using different types of nonionic surfactants (Span 60,40,20,Tween 20,40,60,80,Brij 35,98,72) solely and as mixtures with Span® 60. The formed gels were characterized for entrapment efficiency, vesicle size and in vitro drug release. The optimum proniosomal gel; P-LXN 7 were characterized for pH measurement, transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) as well as Stability study and microbiological evaluation .The results revealed that only Span 60 was able to form stable LXN proniosomal gel when used individually while the other nonionic surfactants formed gels only in combination with Span 60 at different ratios. The optimum proniosomal gel; P-LXN 7 (Span60:Tween60, 9:1) appeared as spherical shaped vesicles having high entrapment efficiency (>80 %), appropriate vesicle size (187 nm) as well as controlled drug release over 12h. DSC confirmed the amorphous nature and the uniformity of LXN inclusion within the vesicles. Physical stability study did not show any significant changes in appearance or entrapment efficiency or vesicle size after storage for 3 months at 4°C. Ocular irritancy test revealed that P-LXN 7 was safe, well tolerable and suitable for ocular delivery. In vivo antibacterial activity of P-LXN 7 evaluated using the susceptibility test and topical therapy of induced ocular conjunctivitis confirmed the enhanced antibacterial therapeutic efficacy of the LXN-proniosomal gel compared to the commercially available LXN eye drops; Orchacin®. Conclusions: Our results suggest that proniosomal gels could provide a promising carrier of LXN for efficient ocular treatment of bacterial conjunctivitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20conjunctivitis" title="bacterial conjunctivitis">bacterial conjunctivitis</a>, <a href="https://publications.waset.org/abstracts/search?q=lomefloxacin%20HCl" title=" lomefloxacin HCl"> lomefloxacin HCl</a>, <a href="https://publications.waset.org/abstracts/search?q=ocular%20drug%20delivery" title=" ocular drug delivery"> ocular drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=proniosomes" title=" proniosomes"> proniosomes</a> </p> <a href="https://publications.waset.org/abstracts/55073/proniosomes-as-a-carrier-for-ocular-drug-delivery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55073.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">25</span> Lateral Capacity of Helical-Pile Groups Subjected to Bearing Combined Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hesham%20Hamdy%20Abdelmohsen">Hesham Hamdy Abdelmohsen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Shawky%20Abdul%20Azizb"> Ahmed Shawky Abdul Azizb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Fawzy%20Aldaghma"> Mona Fawzy Aldaghma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Helical piles have earned considerable attention as an effective deep foundation alternative due to their rapid installation process and their dual purpose in compression and tension. These piles find common uses as foundations for structures like solar panels, wind turbines, offshore platforms, and some kinds of retaining walls. These structures usually transfer different combinations of loads to their helical-pile foundations in the form of axial and lateral loads. Extensive research has been conducted to investigate and understand the behavior of these piles under the influence of either axial or lateral loads. However, the impacts of loading patterns that may act on the helical piles as combinations of axial compression and lateral loads still need more efforts of research work. This paper presents the results of an experimental (Lab tests) and numerical (PLAXIS-3D) study performed on vertical helical-pile groups under the action of combined loads as axial compression (bearing loads), acting successively with lateral (horizontal) loads. The study aims to clarify the effects of key factors, like helix location and direction of lateral load, on the lateral capacity of helical-pile groups and, consequently, on group efficiency. Besides the variation of helix location and lateral load direction, three patterns of successive bearing combined loads were considered, in which the axial vertical compression load was either zero, V1 or V2, whereas the lateral horizontal loads were varied under each vertical compression load. The study concluded that the lateral capacity of the helical-pile group is significantly affected by helix location within the length of the pile shaft. The optimal lateral performance is achieved with helices at a depth ratio of H/L = 0.4. Furthermore, groups of rectangular plan distribution exhibit greater lateral capacity if subjected to lateral horizontal load in the direction of its long axis. Additionally, the research emphasizes that the presence of vertical compression loading can enhance the lateral capacity of the group. This enhancement depends on the value of the vertical compression load, lateral load direction, and helix location, which highlights the complex interaction effect of these factors on the efficiency of helical-pile groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=helical%20piles" title="helical piles">helical piles</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental" title=" experimental"> experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical" title=" numerical"> numerical</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20loading" title=" lateral loading"> lateral loading</a>, <a href="https://publications.waset.org/abstracts/search?q=group%20efficiency" title=" group efficiency"> group efficiency</a> </p> <a href="https://publications.waset.org/abstracts/189201/lateral-capacity-of-helical-pile-groups-subjected-to-bearing-combined-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189201.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">24</span> The Impact of Artificial Intelligence on Digital Factory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Awad%20Wanis%20Gad">Mona Awad Wanis Gad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The method of factory making plans has changed loads, in particular, whilst it's miles approximately making plans the factory building itself. Factory making plans have the venture of designing merchandise, plants, tactics, organization, regions, and the construction of a factory. Ordinary restructuring is turning into greater essential for you to preserve the competitiveness of a manufacturing unit. Regulations in new regions, shorter lifestyle cycles of product and manufacturing era, in addition to a VUCA global (Volatility, Uncertainty, Complexity and Ambiguity) cause extra common restructuring measures inside a factory. A digital factory model is the planning foundation for rebuilding measures and turns into a critical device. Furthermore, digital building fashions are increasingly being utilized in factories to help facility management and manufacturing processes. First, exclusive styles of digital manufacturing unit fashions are investigated, and their residences and usabilities to be used instances are analyzed. Within the scope of research are point cloud fashions, building statistics fashions, photogrammetry fashions, and those enriched with sensor information are tested. It investigated which digital fashions permit a simple integration of sensor facts and in which the variations are. In the end, viable application areas of virtual manufacturing unit models are determined by a survey, and the respective digital manufacturing facility fashions are assigned to the application areas. Ultimately, an application case from upkeep is selected and implemented with the assistance of the best virtual factory version. It is shown how a completely digitalized preservation process can be supported by a digital manufacturing facility version by offering facts. Among different functions, the virtual manufacturing facility version is used for indoor navigation, facts provision, and display of sensor statistics. In summary, the paper suggests a structuring of virtual factory fashions that concentrates on the geometric representation of a manufacturing facility building and its technical facilities. A practical application case is proven and implemented. For that reason, the systematic selection of virtual manufacturing facility models with the corresponding utility cases is evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title="augmented reality">augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20factory%20model" title=" digital factory model"> digital factory model</a>, <a href="https://publications.waset.org/abstracts/search?q=factory%20planning" title=" factory planning"> factory planning</a>, <a href="https://publications.waset.org/abstracts/search?q=restructuring%20digital%20factory%20model" title=" restructuring digital factory model"> restructuring digital factory model</a>, <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title=" photogrammetry"> photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=factory%20planning" title=" factory planning"> factory planning</a>, <a href="https://publications.waset.org/abstracts/search?q=restructuring%20building%20information%20modeling" title=" restructuring building information modeling"> restructuring building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20factory%20model" title=" digital factory model"> digital factory model</a>, <a href="https://publications.waset.org/abstracts/search?q=factory%20planning" title=" factory planning"> factory planning</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a> </p> <a href="https://publications.waset.org/abstracts/188937/the-impact-of-artificial-intelligence-on-digital-factory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188937.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">37</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">23</span> Lock in, Lock Out: A Double Lens Analysis of Local Media Paywall Strategies and User Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20Solvoll">Mona Solvoll</a>, <a href="https://publications.waset.org/abstracts/search?q=Ragnhild%20Kr.%20Olsen"> Ragnhild Kr. Olsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and significance of the study: Newspapers are going through radical changes with increased competition, eroding readerships and declining advertising resulting in plummeting overall revenues. This has lead to a quest for new business models, focusing on monetizing content. This research paper investigates both how local online newspapers have introduced user payment and how the audience has received these changes. Given the role of local media in keeping their communities informed and those in power accountable, their potential impact on civic engagement and cultural integration in local communities, the business model innovations of local media deserves far more research interest. Empirically, the findings are interesting for local journalists, local media managers as well as local advertisers. Basic methodologies: The study is based on interviews with commercial leaders in 20 Norwegian local newspapers in addition to a national survey data from 1600 respondents among local media users. The interviews were conducted in the second half of 2015, while the survey was conducted in September 2016. Theoretically, the study draws on the business model framework. Findings: The analysis indicates that paywalls aim more at reducing digital cannibalisation of print revenue than about creating new digital income. The newspapers are mostly concerned with retaining “old” print subscribers and transform them into digital subscribers. However, this strategy may come at a high price for newspapers if their defensive print strategy drives away younger digital readership and hamper their recruitment potential for new audiences as some previous studies have indicated. Analysis of young reader news habits indicates that attracting the younger audience to traditional local news providers is particularly challenging and that they are more prone to seek alternative news sources than the older audience is. Conclusion: The paywall strategy applied by the local newspapers may be well fitted to stabilise print subscription figures and facilitate more tailored and better services for already existing customers, but far less suited for attracting new ones. The paywall is a short-sighted strategy, which drives away younger readers and paves the road for substitute offerings, particularly Facebook. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20model" title="business model">business model</a>, <a href="https://publications.waset.org/abstracts/search?q=newspapers" title=" newspapers"> newspapers</a>, <a href="https://publications.waset.org/abstracts/search?q=paywall" title=" paywall"> paywall</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20payment" title=" user payment"> user payment</a> </p> <a href="https://publications.waset.org/abstracts/64709/lock-in-lock-out-a-double-lens-analysis-of-local-media-paywall-strategies-and-user-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64709.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">22</span> Formulation, Preparation, and Evaluation of Coated Desloratadine Oral Disintegrating Tablets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20Etman">Mohamed A.

Nada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orally disintegrating tablets (ODTs) are gaining importance as new drug delivery systems and emerged as one of the popular and widely accepted dosage forms, especially for the pediatric and geriatric patients. Their advantages such as administration without water, anywhere, anytime lead to their suitability to geriatric and pediatric patients. They are also suitable for the mentally ill, the bed-ridden and patients who do not have easy access to water. The benefits, in terms of patient compliance, rapid onset of action, increased bioavailability, and good stability make these tablets popular as a dosage form of choice in the current market. These dosage forms dissolve or disintegrate in the oral cavity within a matter of seconds without the need of water or chewing. Desloratadine is a tricyclic antihistaminic, which has a selective and peripheral H1-antagonist action. It is an antagonist at histamine H1 receptors, and an antagonist at all subtypes of the muscarinic acetylcholine receptor. Desloratadine is the major metabolite of loratadine. Twelve different placebos ODT were prepared (F1-F12) using different functional excipients. They were evaluated for their compressibility, hardness and disintegration time. All formulations were non sticky except four formulations; namely (F8, F9, F10, F11). All formulations were compressible with the exception of (F2). Variable disintegration times were found ranging between 20 and 120 seconds. It was found that (F12) showed the least disintegration time (20 secs) without showing any sticking which could be due to the use of high percentage of superdisintegrants. Desloratadine showed bitter taste when formulated as ODT without any treatment. Therefore, different techniques were tried in order to mask its bitter taste. Using Eudragit EPO resulted in complete masking of the bitter taste of the drug and increased the acceptability to volunteers. The compressible non sticky formulations (F1, F3, F4, F5, F6, F7 and F12) were subjected to further evaluation tests after addition of coated desloratadine, including weight uniformity, wetting time, and friability testing.. Fairly good weight uniformity values were observed in all the tested formulations. F12 exhibiting the shortest wetting time (14.7 seconds) and consequently the lowest (20 seconds) disintegration time. Dissolution profile showed that 100% desloratadine release was attained after only 2.5 minutes from the prepared ODT (F12) with dissolution efficiency of 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Desloratadine" title="Desloratadine">Desloratadine</a>, <a href="https://publications.waset.org/abstracts/search?q=orally%20disintegrating%20tablets%20%28ODTs%29" title=" orally disintegrating tablets (ODTs)"> orally disintegrating tablets (ODTs)</a>, <a href="https://publications.waset.org/abstracts/search?q=formulations" title=" formulations"> formulations</a>, <a href="https://publications.waset.org/abstracts/search?q=taste%20masking" title=" taste masking "> taste masking </a> </p> <a href="https://publications.waset.org/abstracts/10491/formulation-preparation-and-evaluation-of-coated-desloratadine-oral-disintegrating-tablets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10491.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">454</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">21</span> Evaluation of Human Amnion Hemocompatibility as a Substitute for Vessels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghasem%20Yazdanpanah">Ghasem Yazdanpanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Kakavand"> Mona Kakavand</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Niknejad"> Hassan Niknejad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: An important issue in tissue engineering (TE) is hemocompatibility. The current engineered vessels are seriously at risk of thrombus formation and stenosis. Amnion (AM) is the innermost layer of fetal membranes that consists of epithelial and mesenchymal sides. It has the advantages of low immunogenicity, anti-inflammatory and anti-bacterial properties as well as good mechanical properties. We recently introduced the amnion as a natural biomaterial for tissue engineering. In this study, we have evaluated hemocompatibility of amnion as potential biomaterial for tissue engineering. Materials and Methods: Amnions were derived from placentas of elective caesarean deliveries which were in the gestational ages 36 to 38 weeks. Extracted amnions were washed by cold PBS to remove blood remnants. Blood samples were obtained from healthy adult volunteers who had not previously taken anti-coagulants. The blood samples were maintained in sterile tubes containing sodium citrate. Plasma or platelet rich plasma (PRP) were collected by blood sample centrifuging at 600 g for 10 min. Hemocompatibility of the AM samples (n=7) were evaluated by measuring of activated partial thromboplastin time (aPTT), prothrombin time (PT), hemolysis, and platelet aggregation tests. P-selectin was also assessed by ELISA. Both epithelial and mesenchymal sides of amnion were evaluated. Glass slide and expanded polytetrafluoroethylene (ePTFE) samples were defined as control. Results: In comparison with glass as control (13.3 ± 0.7 s), prothrombin time was increased significantly while each side of amnion was in contact with plasma (p<0.05). There was no significant difference in PT between epithelial and mesenchymal surfaces (17.4 ± 0.7 s vs. 15.8 ± 0.7 s, respectively). However, aPPT was not significantly changed after incubation of plasma with amnion epithelial and mesenchymal surfaces or glass (28.61 ± 1.39 s, 31.4 ± 2.66 s, glass, 30.76 ± 2.53 s, respectively, p>0.05). Amnion surfaces, ePTFE and glass samples have less hemolysis induction than water considerably (p<0.001), in which no differences were detected. Platelet aggregation measurements showed that platelets were less stimulated by the amnion epithelial and mesenchymal sides, in comparison with ePTFE and glass. In addition, reduction in amount of p-selectin, as platelet activation factor, after incubation of samples with PRP indicated that amnion has less stimulatory effects on platelets than ePTFE and glass. Conclusion: Amnion as a natural biomaterial has the potential to be used in tissue engineering. Our results suggest that amnion has appropriate hemocompatibility to be employed as a vascular substitute. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amnion" title="amnion">amnion</a>, <a href="https://publications.waset.org/abstracts/search?q=hemocompatibility" title=" hemocompatibility"> hemocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=biomaterial" title=" biomaterial"> biomaterial</a> </p> <a href="https://publications.waset.org/abstracts/11352/evaluation-of-human-amnion-hemocompatibility-as-a-substitute-for-vessels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11352.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">395</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">20</span> Tension-Free Vaginal Tape Secur (TVT Secur) versus Tension-Free Vaginal Tape-Obturator (TVT-O) from inside to outside in Surgical Management of Genuine Stress Urinary Incontinence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Mohamed%20Ibrahim%20Hassanin">Ibrahim Mohamed Ibrahim Hassanin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hany%20Hassan%20Mostafa"> Hany Hassan Mostafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Mohamed%20Shaban"> Mona Mohamed Shaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahlam%20El%20Said%20Kamel"> Ahlam El Said Kamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: New so-called minimally invasive devices have been developed to limit groin pain after sling placement for treatment of stress urinary incontinence (SUI) to minimize the risk of postoperative pain and organ perforation. A new generation of suburethral slings was described that avoided skin incision to pull out and tension the sling. Evaluation of this device through prospective short-term series has shown controversial results compared with other tension-free techniques. The aim of this study is to compare success rates and complications for tension-free vaginal tape secur (TVT secur) and trans-obturator sub urethral tape inside-out technique (TVT-O) for treatment of stress urinary incontinence (SUI). Materials and Methods: Fifty patients with genuine SUI were divided into two groups: group S (n=25) were operated upon using (TVT secur) and group O (n=25) were operated upon using trans-obturator suburethral tape inside-out technique (TVT-O). Success rate, quality of life and postoperative complications such as groin pain, urgency, urine retention and vaginal tape erosion were reported in both groups at one, three, and six months after surgery. Results: As regards objective cure rate at one, three, six months intervals; there was a significant difference between group S (56%, 64%, and 60%), and group O (80%, 88%, and 88%) respectively (P <0.05). As regards subjective cure rate at one, three, six months intervals; there was a significant difference between group S (44%, 44%, and 48%), and group O (76%, 80%, and 80%) respectively (P <0.05). Quality of life (QoL) parameters improved significantly in cured patients with no difference between both groups. As regards complications, group O had a higher frequency of complications than group S; groin pain (12% vs 12% p= 0.05), urgency (4% (1 case) vs 0%), urine retention (8% (2 cases) vs 0%), vaginal tape erosion (4% (1 case) vs 0%). No cases were complicated with wound infection. Conclusion: Compared to TVT secur, TVT-O showed higher subjective and objective cure rates after six months but higher rate of complications. Both techniques were comparable as regards improvement of quality of life after surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress%20urinary%20incontinence" title="stress urinary incontinence">stress urinary incontinence</a>, <a href="https://publications.waset.org/abstracts/search?q=trans-vaginal%20tape-obturator" title=" trans-vaginal tape-obturator"> trans-vaginal tape-obturator</a>, <a href="https://publications.waset.org/abstracts/search?q=TVT%20Secur" title=" TVT Secur"> TVT Secur</a>, <a href="https://publications.waset.org/abstracts/search?q=TVT-O" title=" TVT-O"> TVT-O</a> </p> <a href="https://publications.waset.org/abstracts/8928/tension-free-vaginal-tape-secur-tvt-secur-versus-tension-free-vaginal-tape-obturator-tvt-o-from-inside-to-outside-in-surgical-management-of-genuine-stress-urinary-incontinence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8928.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">360</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">19</span> Structural Investigation of the GAF Domain Protein BPSL2418 from Burkholderia pseudomallei</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mona%20G.%20Alharbi">Mona G. Alharbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new family of methionine-sulfoxide reductase (Msr) was recently discovered and was named free methionine sulfoxide reductase (fRMsr). This family includes enzymes with a reductase activity toward the free R isomer of a methionine sulfoxide substrate. The fRMsrs have a GAF domain topology, a domain, which was previously identified as having in some cases a cyclic nucleotide phosphodiesterase activity. The classification of fRMsrs as GAF domains revealed a new function can be added to the GAF domain family. Interestingly the four members identified in the fRMsr family share the GAF domain structure and the presence of three conserved cysteines in the active site with free R methionine sulfoxide substrate specificity. This thesis presents the crystal structures of reduced, free Met-SO substrate-bound and MES-bound forms of a new fRMsr from Burkholderia pseudomallei (BPSL2418). BPSL2418 was cloned, overexpressed and purified to enable protein crystallization. The crystallization trials for reduced, Met-SO-bound and MES-bound forms of BPSL2418 were prepared and reasonable crystals of each form were produced. The crystal structures of BPSL2418MES, BPSL2418Met-SO and BPSL2418Reduced were solved at 1.18, 1.4 and 2.0Å, respectively by molecular replacement. The BPSL2418MES crystal belongs to space group P 21 21 21 while BPSL2418Met-SO and BPSL2418Reduced crystals belong to space group P 1 21 1. All three forms share the GAF domain structure of six antiparallel β-strands and four α-helices with connecting loops. The antiparallel β-strands (β1, β2, β5 and β6) are located in the center of the BPSL2418 structure flanked on one side by a three α-helices (α1, α2 and α4) and on the other side by a (loop1, β3, loop2, α3, β4 loop4) unit where loop4 forms a capping flap and covers the active site. The structural comparison of the three forms of BPSL2418 indicates that the catalytically important cysteine is CYS109, where the resolving cysteine is CYS75, which forms a disulfide bond with CYS109. They also suggest that the third conserved cysteine in the active site, CYS85, which is located in α3, is a non-essential cysteine for the catalytic function but it may play a role in the binding of the substrate. The structural comparison of the three forms reveals that conformational changes appear in the active site particularly involving loop4 and CYS109 during catalysis. The 3D structure of BPSL2418 shows strong structure similarity to fRMsrs enzymes, which further suggests that BPSL2418 acts as a free Met-R-SO reductase and shares the catalytic mechanism of fRMsr family. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burkholderia%20pseudomallei" title="Burkholderia pseudomallei">Burkholderia pseudomallei</a>, <a href="https://publications.waset.org/abstracts/search?q=GAF%20domain%20protein" title=" GAF domain protein"> GAF domain protein</a>, <a href="https://publications.waset.org/abstracts/search?q=methionine%20sulfoxide%20reductase" title=" methionine sulfoxide reductase"> methionine sulfoxide reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20crystallization" title=" protein crystallization"> protein crystallization</a> </p> <a href="https://publications.waset.org/abstracts/77202/structural-investigation-of-the-gaf-domain-protein-bpsl2418-from-burkholderia-pseudomallei" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77202.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">386</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">18</span> The Impact of Climate Change on Sustainable Aquaculture Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peyman%20Mosberian-Tanha">Peyman Mosberian-Tanha</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Rezaei"> Mona Rezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aquaculture sector is the fastest growing food sector with annual growth rate of about 10%. The sustainability of aquaculture production, however, has been debated mainly in relation to the feed ingredients used for farmed fish. The industry has been able to decrease its dependency on marine-based ingredients in line with policies for more sustainable production. As a result, plant-based ingredients have increasingly been incorporated in aquaculture feeds, especially in feeds for popular carnivorous species, salmonids. The effect of these ingredients on salmonids’ health and performance has been widely studied. In most cases, plant-based diets are associated with varying degrees of health and performance issues across salmonids, partly depending on inclusion levels of plant ingredients and the species in question. However, aquaculture sector is facing another challenge of concern. Environmental challenges in association with climate change is another issue the aquaculture sector must deal with. Data from trials in salmonids subjected to environmental challenges of various types show adverse physiological responses, partly in relation to stress. To date, there are only a limited number of studies reporting the interactive effects of adverse environmental conditions and dietary regimens on salmonids. These studies have shown that adverse environmental conditions exacerbate the detrimental effect of plant-based diets on digestive function and health in salmonids. This indicates an additional challenge for the aquaculture sector to grow in a sustainable manner. The adverse environmental conditions often studied in farmed fish is the change in certain water quality parameters such as oxygen and/or temperature that are typically altered in response to climate change and, more specifically, global warming. In a challenge study, we observed that the in the fish fed a plant-based diet, the fish’s ability to absorb dietary energy was further reduced when reared under low oxygen level. In addition, gut health in these fish was severely impaired. Some other studies also confirm the adverse effect of environmental challenge on fish’s gut health. These effects on the digestive function and gut health of salmonids may result in less resistance to diseases and weaker performance with significant economic and ethical implications. Overall, various findings indicate the multidimensional negative effects of climate change, as a major environmental issue, in different sectors, including aquaculture production. Therefore, a comprehensive evaluation of different ways to cope with climate change is essential for planning more sustainable strategies in aquaculture sector. <p
