class="card-text"><strong>Abstract:</strong></p> Intravenous and inhaled magnesium sulfate (MgSO₄) had been recently used as an adjuvant therapy in cases suffering from the wheezy chest. Objective: We aimed to determine the possible change in the hemodynamic state in cases received intravenous or inhaled MgSO₄ in comparison to cases received standard treatment in critically ill infants and children with the wheezy chest. Methods: A randomized controlled trial comprised 81 patients suffering from wheezy chest divided into 3 groups. In addition to bronchodilators and systemic steroids, MgSO₄ was given by inhalation in group A, intravenously in group B, and group C didn't receive MgSO₄. The hemodynamic state was determined by assessment of blood pressure, heart rate, capillary refill time and the need for shock therapy or inotropic support just before and 24 hours after receiving treatment in 3 groups. Results: There was no significant difference in the hemodynamic state of the studied groups before and after treatment. Means of blood pressure were 102.2/63.2, 105.1/64.8 before and after inhaled MgSO₄; respectively. Means of blood pressure were 105.5/64.2, 104.1/64.9 before and after intravenous MgSO₄; respectively. Means of blood pressure were 107.4/62.8, 104.4/62.1 before and after standard treatment, respectively. There was a statistically insignificant reduction of the means of the heart rate in group A and group B after treatment rather than group C. There was no associated prolongation in capillary refill time and/or the need for inotropic support or shock therapy after treatment in the studied groups. Conclusion: MgSO₄ is a safe adjuvant therapy and not associated with significant alteration in the hemodynamic state in critically ill infants and children with the wheezy chest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critically%20ill%20infants%20and%20children" title="critically ill infants and children">critically ill infants and children</a>, <a href="https://publications.waset.org/abstracts/search?q=inhaled%20MgSO%E2%82%84" title=" inhaled MgSO₄"> inhaled MgSO₄</a>, <a href="https://publications.waset.org/abstracts/search?q=intravenous%20MgSO%E2%82%84" title=" intravenous MgSO₄"> intravenous MgSO₄</a>, <a href="https://publications.waset.org/abstracts/search?q=wheezy%20chest" title=" wheezy chest"> wheezy chest</a> </p> <a href="https://publications.waset.org/abstracts/92298/hemodynamic-effects-of-magnesium-sulphate-therapy-in-critically-ill-infants-and-children-with-wheezy-chest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92298.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">148</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">59</span> Durability Enhancement of CaSO4 in Repetitive Operation of Chemical Heat Pump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Shiren">Y.

Kobayashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An important problem for the CaSO4/CaSO4･1/2H2O Chemical heat pump (CHP) is that the material is deactivated through repetitive reaction between hydration and dehydration in which the crystal phase of the material is transformed from III-CaSO4 to II-CaSO4. We investigated suppression on the phase change by adding a sulfated compound. The most effective material was MgSO4. MgSO4 doping increased the durability of CaSO4 in the actual CHP repetitive cycle of hydration/dehydration to 3.6 times that of undoped CaSO4. The MgSO4-doped CaSO4 showed a higher phase transition temperature and activation energy for crystal transformation from III-CaSO4 to II-CaSO4. MgSO4 doping decreased the crystal lattice size of CaSO4･1/2H2O and II-CaSO4 to smaller than that of undoped CaSO4. Modification of the crystal structure is considered to be related to the durability change in CaSO4 resulting from MgSO4 doping. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CaSO4" title="CaSO4">CaSO4</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20heat%20pump" title=" chemical heat pump"> chemical heat pump</a>, <a href="https://publications.waset.org/abstracts/search?q=durability%20of%20chemical%20heat%20storage%20material" title=" durability of chemical heat storage material"> durability of chemical heat storage material</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20storage" title=" heat storage"> heat storage</a> </p> <a href="https://publications.waset.org/abstracts/25419/durability-enhancement-of-caso4-in-repetitive-operation-of-chemical-heat-pump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25419.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">579</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">58</span> Exploring the Effect of Cellulose Based Coating Incorporated with CaCl2 and MgSO4 on Shelf Life Extension of Kinnow (Citrus reticulata blanco) Cultivar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Atif%20Randhawa">Muhammad Atif Randhawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nadeem"> Muhammad Nadeem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kinnow (Citrus reticulate Blanco) is nutritious and perishable fruit with high juice content, and also rich source of vitamin-C. In Pakistan, kinnow export is limited due to inadequate post-harvest handling and lack of satisfactory storage practices. Considering these issues, the present study was designed to evaluate the effect of hydroxypropyl methylcellulose (HPMC) coating in combination with CaCl2 and MgSO4 on shelf life extension of kinnow. Fruits were treated with different levels of CaCl2 and MgSO4 followed by HPMC coating (3 and 5%) and stored at 10°C with 80% relative humidity for 6 weeks. Fruits were analyzed for various physico-chemical parameters on weekly basis. During this study lower fruit firmness (0.24Nm-2), loss in weight (0.64%) and ethylene production (0.039 µL•kg-1•hr-1) was observed in fruits treated with 1% CaCl2 + 1% MgSO4 + 5% HPMC (T6) during storage of 42 days. Minimum chilling injury indexes 0.22% and 0.61% were recorded in treatments T4 and T6, respectively. T6 showed higher values of titerable acidity (0.29%) and ascorbic acid contents (39.82mg/100g). Minimum TSS (9.62°Brix) was found in fruits of T6. Overall T6 showed significantly better results for various parameters, as compared to all other treated and control fruits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=firmness" title="firmness">firmness</a>, <a href="https://publications.waset.org/abstracts/search?q=kinnow%20coating" title=" kinnow coating"> kinnow coating</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical" title=" physicochemical"> physicochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a> </p> <a href="https://publications.waset.org/abstracts/41488/exploring-the-effect-of-cellulose-based-coating-incorporated-with-cacl2-and-mgso4-on-shelf-life-extension-of-kinnow-citrus-reticulata-blanco-cultivar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41488.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">430</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">57</span> Efficacy and Safety of Inhaled Nebulized Chemotherapy in Treatment of Patients with Newly Diagnosed Pulmonary Tuberculosis in Comparison to Standard Antimycobacterial Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kuzhko">M.

Materials and methods: The study involved 68 patients aged between 20 and 70 years with newly diagnosed pulmonary tuberculosis. Patients were allocated to two groups. The first (main, n=21) group of patients received standard chemotherapy and further 0.15 g of isoniazid and rifampicin 0.15 g inhaled through a nebulizer, also they received salmeterol 50 mcg + fluticasone propionate 250 mcg at 2 breaths twice a day for 2 months. The second (control, n=47) group of patients received standard chemotherapy, consisting of orally administered isoniazid (0.3 g), rifampicin (0.6 g), pyrazinamide (2 g), ethambutol (1.2 g) with a dose reduction after the intensive phase of the therapy. The anti-TB drugs were procured through the Ukraine’s centralized national supply system. Results: Intoxication symptoms in the first group reduced following 1.39±0.18 months, whereas in the second group, intoxication symptoms reduced following 2.7±0.1 months, p<.001. Moreover, respiratory symptoms regression in the first group was observed following 1.6±0.2 months, whereas in the second group – following 2.5±0.2 months, p<0.05. Bacillary excretion period evaluated within 1 month was reduced, as it was shown by 66.6±10.5% in the main group compared to 27.6±6.5%, p<0.05, in the control group. In addition, period of cavities healing was reduced to 2.9±0.2 months in the main group compared to 3.7±0.1 months, p<0.05, in the control group. Residual radiological lung damage findings (large residual changes) were observed in 22 (23.8±9.5 %) patients of the main group versus 24 (51.0±7.2 %) patients in the control group, p<0.05. After completion of treatment scar stenosis of the bronchi II-III art. diagnosed in 3 (14.2±7.8%) patients in main group and 17 (68.0±6.8%) - control group, p<0.05. The duration of hospital treatment was 2.4±0.4 months in main group and 4.1±0.4 months in control group, p<0.05. Conclusion: Administration of of inhaled nebulized chemotherapy in patients with newly diagnosed pulmonary tuberculosis resulted in a comparatively quick reduction of disease manifestation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inhaled%20nebulized%20chemotherapy" title="inhaled nebulized chemotherapy">inhaled nebulized chemotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20tuberculosis" title=" pulmonary tuberculosis"> pulmonary tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20of%20tuberculosis" title=" treatment of tuberculosis"> treatment of tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/61666/efficacy-and-safety-of-inhaled-nebulized-chemotherapy-in-treatment-of-patients-with-newly-diagnosed-pulmonary-tuberculosis-in-comparison-to-standard-antimycobacterial-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61666.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Hematuria Following Magnesium Sulfate Administration in a Pregnant Patient with Renal Tubular Acidosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jan%20Gayl%20Barcelon">Jan Gayl Barcelon</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Gorgonio"> N. Gorgonio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renal tubular acidosis, a medical condition that involves the accumulation of acid in the body due to failure of the kidneys to maintain normal urine and blood pH, is rarely encountered in pregnancy. The effect of renal tubular acidosis in pregnancy is not fully established. It may worsen during pregnancy and cause maternal and fetal morbidity. A 30-year-old primigravida was diagnosed with renal tubular acidosis at age 7, but due to uncontrolled disease progression, she developed rickets at age 10. She was first seen in our institution at eight weeks gestation and maintained on bicarbonate and potassium supplementation. At 26 weeks gestation, she was diagnosed with polyhydramnios, causing on and off irregular uterine contractions. At 30 weeks gestation, despite oral Nifedipine, premature labor was uncontrolled; hence she was admitted for tocolysis. With elevated creatinine (123 umol/L) and a normal blood urea nitrogen level (6.70 mmol/L), she was referred to Nephrology Service, which cleared the patient prior to MgSO₄ drip. Dosing of 4g MgSO₄ over 20 minutes followed by a maintenance of 2g/hour x 24 hours for neuroprotection and tocolysis was ordered. Two hours after MgSO₄ drip initiation, hematuria developed with adequate urine output. The infusion was immediately stopped. The serum magnesium level was high normal at 6.7 mEq/L. After 4 hours of renal clearance, the repeat serum magnesium level was normal (2.7 mEq/L) and with clear urine output. The patient was then given Nifedipine 30mg/tab, 3x a day which controlled the uterine contractions. At 37 weeks gestation, the patient delivered via primary low transverse Cesarean Section to a live female with a birthweight of 2470gm, appropriate for gestational age. The use of MgSO₄ for the control of premature labor in patients with chronic renal disease secondary to renal tubular can cause hematuria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hematuria" title="hematuria">hematuria</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20sulfate" title=" magnesium sulfate"> magnesium sulfate</a>, <a href="https://publications.waset.org/abstracts/search?q=premature%20labor" title=" premature labor"> premature labor</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20tubular%20acidosis" title=" renal tubular acidosis"> renal tubular acidosis</a> </p> <a href="https://publications.waset.org/abstracts/137584/hematuria-following-magnesium-sulfate-administration-in-a-pregnant-patient-with-renal-tubular-acidosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137584.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">129</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">55</span> Nebulized Magnesium Sulfate in Acute Moderate to Severe Asthma in Pediatric Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lubna%20M.%20Zakaryia%20Mahmoud">Lubna M.

The participants in the study were divided in two groups; Group A (study group) received inhaled salbutamol solution (0.15 ml/kg) plus isotonic magnesium sulfate 2 ml in a nebulizer chamber. Group B (control group): received nebulized salbutamol solution (0.15 ml/kg) diluted with placebo (2 ml normal saline). Both groups received inhaled solution every 20 minutes that was repeated for three doses. They were evaluated using the Pediatric Asthma Severity Score (PASS), oxygen saturation using portable pulse oximetry and peak expiratory flow rate using a portable peak expiratory flow meter at initially recorded as zero-minute assessment and every 20 minutes from the end of each nebulization (nebulization lasts 5-10 minutes) recorded as 20, 40 and 60-minute assessments. Regarding PASS, comparison showed non-significant difference with p-value 0.463, 0.472, 0.0766 at 20, 40 and 60 minutes. Regarding oxygen saturation, improvement was more significant towards group A starting from 40 min with significant p-value=0.000. At 60 min p-value=0.000. Although mean PEFR significantly improved from zero-min in both groups; however, improvement was more significant in group A with significant p-value = 0.015, 0.001, 0.001 at 20 min, 40 min and 60 min, respectively. The conclusion this study suggests is that inhaled magnesium sulfate is an efficient add on drug to standard β- agonist inhalation used in the treatment of moderate to severe asthma exacerbations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nebulized" title="nebulized">nebulized</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20sulfate" title=" magnesium sulfate"> magnesium sulfate</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20asthma" title=" acute asthma "> acute asthma </a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric" title=" pediatric"> pediatric</a> </p> <a href="https://publications.waset.org/abstracts/59092/nebulized-magnesium-sulfate-in-acute-moderate-to-severe-asthma-in-pediatric-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59092.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">183</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">54</span> The Optimisation of Salt Impregnated Matrices as Potential Thermochemical Storage Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20J.%20Sutton">Robert J.

A simple moisture experiment represents the hydration, whilst thermogravimetric analysis (TGA) represents the dehydration. Further experiments to approximate the energy density and to determine the peak output temperatures of the SIMs are conducted. The CaCl2 SIM is deemed the best performing SIM across most experiments, whilst the results of MgSO4 SIM indicate difficulty associated with energy recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrated%20states" title="hydrated states">hydrated states</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-seasonal%20heat%20storage" title=" inter-seasonal heat storage"> inter-seasonal heat storage</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20sorption" title=" moisture sorption"> moisture sorption</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20in%20matrix" title=" salt in matrix"> salt in matrix</a> </p> <a href="https://publications.waset.org/abstracts/28423/the-optimisation-of-salt-impregnated-matrices-as-potential-thermochemical-storage-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28423.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">554</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">53</span> Optimization of Media for Enhanced Fermentative Production of Mycophenolic Acid by Penicillium brevicompactum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shraddha%20Digole">Shraddha Digole</a>, <a href="https://publications.waset.org/abstracts/search?q=Swarali%20Hingse"> Swarali Hingse</a>, <a href="https://publications.waset.org/abstracts/search?q=Uday%20Annapure"> Uday Annapure</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycophenolic acid (MPA) is an immunosuppressant; produced by Penicillium Sp. Box-Behnken statistical experimental design was employed to optimize the condition of Penicillium brevicompactum NRRL 2011 for mycophenolic acid (MPA) production. Initially optimization of various physicochemical parameters and media components was carried out using one factor at a time approach and significant factors were screened by Taguchi L-16 orthogonal array design. Taguchi design indicated that glucose, KH2PO4 and MgSO4 had significant effect on MPA production. These variables were selected for further optimization studies using Box-Behnken design. Optimised fermentation condition, glucose (60 g/L), glycine (28 g/L), L-leucine (1.5g/L), KH2PO4 (3g/L), MgSO4.7H2O (1.5g/L), increased the production of MPA from 170 mg/L to 1032.54 mg/L. Analysis of variance (ANOVA) showed a high value of coefficient of determination R2 (0.9965), indicating a good agreement between experimental and predicted values and proves validity of the statistical model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Box-Behnken%20design" title="Box-Behnken design">Box-Behnken design</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=mycophenolic%20acid" title=" mycophenolic acid"> mycophenolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Penicillium%20brevicompactum" title=" Penicillium brevicompactum"> Penicillium brevicompactum</a> </p> <a href="https://publications.waset.org/abstracts/20009/optimization-of-media-for-enhanced-fermentative-production-of-mycophenolic-acid-by-penicillium-brevicompactum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20009.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">452</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">52</span> The Optimization of Immobilization Conditions for Biohydrogen Production from Palm Industry Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20W.%20Zularisam">A.

LS2 was immobilised by entrapment in polyethylene glycol (PEG) gel beads to improve the biohydrogen production rate from palm oil mill effluent (POME). We sought to explore and optimise the hydrogen production capability of the immobilised cells by studying the conditions for cell immobilisation, including PEG concentration, cell loading and curing times, as well as the effects of temperature and K2HPO4 (500–2000 mg/L), NiCl2 (0.1–5.0 mg/L), FeCl2 (100–400 mg/L) MgSO4 (50–200 mg/L) concentrations on hydrogen production rate. The results showed that by optimising the PEG concentration (10% w/v), initial biomass (2.2 g dry weight), curing time (80 min) and temperature (37 °C), as well as the concentrations of K2HPO4 (2000 mg/L), NiCl2 (1 mg/L), FeCl2 (300 mg/L) and MgSO4 (100 mg/L), a maximum hydrogen production rate of 7.3 L/L-POME/day and a yield of 0.31 L H2/g chemical oxygen demand were obtained during continuous operation.

Methods: Thirty Sprague- Dawley male rats were included. Rats were randomly separated into 5 groups. First group was administered saline only while the rest had received amitryptiline 100 mg/kg + saline, 5 mg/kg metoprolol, 20 ml/kg lipid emulsion and 75 mg/kg magnesium sulphate (MgSO4) intraperitoneally. ECG at DI lead, biochemical tests following euthanasia were performed in all groups after 1 hour of administration. Cardiac tissues were removed, sections were prepared and examined. Results: QTc values were significantly shorter in the rest when compared to amitryptiline+ saline group. While lipid emulsion did not affect proBNP and troponin values biochemically as compared to that of the control group, histologically, it was with reduced caspase 3 expression. Though statistically insignificant in the context of biochemical changes, pro-BNP and urea levels were lower in the metoprolol group when compared to controls. Similarly, metoprolol had no statistically significant effect on histological caspase 3 expression in the group that was treated with amitryptiline+metoprolol. On the other hand, there was a statistically significant decrease in Troponin, pro-BNP and urea levels as well as significant decline in histological caspase 3 expression within the MgSO4 group when compared to controls. Conclusion: As still a frequent cause of mortality in emergency units, administration of MgSO4, lipid emulsion and metoprolol might be beneficial in alternative treatment of cardiovascular toxicity caused by tricyclic antidepressant overdose, whether intake would be intentional or accidental. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amitryptiline" title="amitryptiline">amitryptiline</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20toxicity" title="cardiovascular toxicity">cardiovascular toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20QT" title=" long QT"> long QT</a>, <a href="https://publications.waset.org/abstracts/search?q=Rat%20Model" title=" Rat Model"> Rat Model</a> </p> <a href="https://publications.waset.org/abstracts/80037/the-effects-of-lipid-emulsion-magnesium-sulphate-and-metoprolol-in-amitryptiline-induced-cardiovascular-toxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80037.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">176</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">50</span> Effect of Hydroxy Propyl Methyl Cellulose (HPMC) Coating in Combination with MGSO4 on Some Guava Cultivars </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Randhawa">Muhammad Randhawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nadeem"> Muhammad Nadeem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Guava (Psidium guajava L.) is a vital source of minerals, vitamins, dietary fiber and antioxidants. Owing to highly perishable nature and proning towards chilling injury, diseases, insect-pests and physical damage the main drawbacks of guava after harvesting, present study was designed. Due to its delicacy in physiology, economic importance, effects of pre and postharvest factors and maturity indices, guava fruits should be given prime importance for good quality attributes. In this study guava fruits were stored at 10°C with 80% relative humidity after treating with different levels of sulphate salt of magnesium followed by dipping in cellulose based edible coating hydroxy propyl methyl cellulose (HPMC). The main objective of this coating was to enhance the shelf life of guava by inhibiting the respiration and also by binding the dissolved solids with salt application. Characterization for quality attributes including physical, physiological and bio chemical analysis was performed after every 7 days interval till the fruit remains edible during the storage period of 4 weeks. Finally, data obtained was subjected to statistical analysis. It was concluded on statistical basis that Surahi variety (treated with 5% MgSO4) showed best storage stability and kept its original quality up to almost 23 days during storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edible%20coating" title="edible coating">edible coating</a>, <a href="https://publications.waset.org/abstracts/search?q=guava%20cultivars" title=" guava cultivars"> guava cultivars</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20attributes" title=" physicochemical attributes"> physicochemical attributes</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a> </p> <a href="https://publications.waset.org/abstracts/41480/effect-of-hydroxy-propyl-methyl-cellulose-hpmc-coating-in-combination-with-mgso4-on-some-guava-cultivars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41480.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">325</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">49</span> A Clinical Study of Tracheobronchopathia Osteochondroplastica: Findings from a Large Chinese Cohort</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Zhu">Ying Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ning%20Wu"> Ning Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hai-Dong%20Huang"> Hai-Dong Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Chao%20Dong"> Yu-Chao Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Qin-Ying%20Sun"> Qin-Ying Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Zhang"> Wei Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qin%20Wang"> Qin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiang%20Li"> Qiang Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and study aims: Tracheobronchopathia osteochondroplastica (TO) is an uncommon disease of the tracheobronchial system that leads to narrowing of the airway lumen from cartilaginous and/or osseous submucosal nodules. The aim of this study is to perform a detailed review of this rare disease in a large cohort of patients with TO proven by fiberoptic bronchoscopy from China. Patients and Methods: Retrospective chart review was performed on 41,600 patients who underwent bronchoscopy in the Department of Respiratory Medicine of Changhai Hospital between January 2005 and December 2012. Cases of TO were identified based on characteristic features during bronchoscopic examination. Results: 22 cases of bronchoscopic TO were identified. Among whom one-half were male and the mean age was 47.45 ±10.91 years old. The most frequent symptoms at presentation were chronic cough (n=14) and increased sputum production (n=10). Radiographic abnormalities were observed in 3/18 patients and findings on computed tomography consistent with TO such as beaded intraluminal calcifications and/or increased luminal thickenings were observed in 18/22 patients. Patients were classified into the following categories based on the severity of bronchoscopic findings: Stage I (n=2), Stage II (n=6) and Stage III(n=14). The result that bronchoscopic improvement was observed in 2 patients administered with inhaled corticosteroids suggested that resolution of this disease is possible. Conclusions: TO is a benign disease with slow progression, which could be roughly divided into 3 stages on the basis of the characteristic endoscopic features and histopathologic findings. Chronic inflammation was thought to be more important than the other existing plausible hypotheses in the course of TO. Inhaled corticosteroids might have some impact on patients at Stage I/II. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20obstruction" title="airway obstruction">airway obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchoscopy" title=" bronchoscopy"> bronchoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=etiology" title=" etiology"> etiology</a>, <a href="https://publications.waset.org/abstracts/search?q=Tracheobronchopathia%20osteochondroplastica%20%28TO%29" title=" Tracheobronchopathia osteochondroplastica (TO)"> Tracheobronchopathia osteochondroplastica (TO)</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/17926/a-clinical-study-of-tracheobronchopathia-osteochondroplastica-findings-from-a-large-chinese-cohort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17926.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">464</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">48</span> Layer-by-Layer Modified Ceramic Membranes for Micropollutant Removal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jenny%20Radeva">Jenny Radeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Anke-Gundula%20Roth"> Anke-Gundula Roth</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Goebbert"> Christian Goebbert</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Niestroj-Pahl"> Robert Niestroj-Pahl</a>, <a href="https://publications.waset.org/abstracts/search?q=Lars%20Daehne"> Lars Daehne</a>, <a href="https://publications.waset.org/abstracts/search?q=Axel%20Wolfram"> Axel Wolfram</a>, <a href="https://publications.waset.org/abstracts/search?q=Juergen%20Wiese"> Juergen Wiese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ceramic membranes for water purification combine excellent stability with long-life characteristics and high chemical resistance. Layer-by-Layer coating is a well-known technique for customization and optimization of filtration properties of membranes but is mostly used on polymeric membranes. Ceramic membranes comprising a metal oxide filtration layer of Al2O3 or TiO2 are charged and therefore highly suitable for polyelectrolyte adsorption. The high stability of the membrane support allows efficient backwash and chemical cleaning of the membrane. The presented study reports metal oxide/organic composite membrane with an increased rejection of bivalent salts like MgSO4 and the organic micropollutant Diclofenac. A self-build apparatus was used for applying the polyelectrolyte multilayers on the ceramic membrane. The device controls the flow and timing of the polyelectrolytes and washing solutions. As support for the Layer-by-Layer coat, ceramic mono-channel membranes were used with an inner capillary of 8 mm diameter, which is connected to the coating device. The inner wall of the capillary is coated subsequently with polycat- and anions. The filtration experiments were performed with a feed solution of MgSO4 and Diclofenac. The salt content of the permeate was detected conductometrically and Diclofenac was measured with UV-Adsorption. The concluded results show retention values of magnesium sulfate of 70% and diclofenac retention of 60%. Further experimental research studied various parameters of the composite membrane-like Molecular Weight Cut Off and pore size, Zeta potential and its mechanical and chemical robustness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20purification" title="water purification">water purification</a>, <a href="https://publications.waset.org/abstracts/search?q=polyelectrolytes" title=" polyelectrolytes"> polyelectrolytes</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20modification" title=" membrane modification"> membrane modification</a>, <a href="https://publications.waset.org/abstracts/search?q=layer-by-layer%20coating" title=" layer-by-layer coating"> layer-by-layer coating</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20membranes" title=" ceramic membranes"> ceramic membranes</a> </p> <a href="https://publications.waset.org/abstracts/138651/layer-by-layer-modified-ceramic-membranes-for-micropollutant-removal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138651.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">245</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">47</span> Development of Hydrophilic Materials for Nanofiltration Membrane Achieving Dual Resistance to Fouling and Chlorine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xi%20Quan%20Cheng">Xi Quan Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Chao%20Xu"> Yan Chao Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Jiang"> Xu Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Shao"> Lu Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Cher%20Hon%20Lau"> Cher Hon Lau </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A hydrophilic thin-ﬁlm-composite (TFC) nanofiltration (NF) membrane has been developed through the interfacial polymerization (IP) of amino-functional polyethylene glycol (PEG) and trimesoyl chloride. The selective layer is formed on a polyethersulfone (PES) support that is characterized using FTIR, XPS and SEM, and is dependent on monomer immersion duration, and the concentration of monomers and additives. The higher hydrophilicity alongside the larger pore size of the PEG-based selective layer is the key to a high water flux of 66.0 L m-2 h-1 at 5.0 bar. With mean pore radius of 0.42 nm and narrow pore size distribution, the MgSO4 rejections of the PEG based PA TFC NF membranes can reach up to 80.2 %. The hydrophilic PEG based membranes shows positive charged since the isoelectric points range from pH=8.9 to pH=9.1 and the rejection rates for different salts of the novel membranes are in the order of R(MgCl2)>R(MgSO4)>R(NaCl)>R(Na2SO4). The pore sizes and water permeability of these membranes are tailored by varying the molecular weight and molecular architecture of amino-functional PEG. Due to the unique structure of the selective layer of the PEG based membranes consisting of saturated aliphatic construction unit (CH2-CH2-O), the membranes demonstrate dual resistance to fouling and chlorine. The membranes maintain good salt rejections and high water flux of PEG based membranes after treatment by 2000 ppm NaClO for 24 hours. Interestingly, the PEG based membranes exhibit excellent fouling resistance with a water flux recovery of 90.2 % using BSA as a model molecule. More importantly, the hydrophilic PEG based NF membranes have been exploited to separate several water soluble antibiotics (such as tobramycin, an aminoglycoside antibiotic applied in the treatment of various types of bacterial infections), showing excellent performance in concentration or removal of antibioics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofiltration" title="nanofiltration">nanofiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20separation" title=" antibiotic separation"> antibiotic separation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophilic%20membrane" title=" hydrophilic membrane"> hydrophilic membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20flux" title=" high flux "> high flux </a> </p> <a href="https://publications.waset.org/abstracts/42799/development-of-hydrophilic-materials-for-nanofiltration-membrane-achieving-dual-resistance-to-fouling-and-chlorine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42799.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> A Prospective Randomised Observational Study of Obstructed Total Anamalous Pulmonary Venous Connection (TAPVC) Repair Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanjeev%20Singh">Sanjeev Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Obstructed total anomalous pulmonary venous connection (OTAPVC) typically presents with severe cardiovascular decompensation and requires urgent surgical management. Pulmonary arterial hypertension (PAH) is a major risk factor affecting mortality. Perioperative management focuses on providing inotropic support and managing potential pulmonary hypertensive episodes. The aim of this study was to determine the outcome of patients with high pulmonary arterial pressure (PAP) with milrinone alone and a combination of milrinone and inhaled nitric oxide (INO). Material and Methods: After the approval of the ethical committee, this single-center prospective randomized and observational study was conducted over a period of two years among eighty-six patients with obstructed TAPVC repair with severe PAH. Group-I patients received milrinone, and Group-II patients received both milrinone (after aortic cross-clamp removal) and INO during the post-operative period at the cardiac care unit (CCU). Clinical outcomes such as ventilation time, length of stay (LOS) in the CCU, LOS in the hospital, complications, and hospital mortality were compared between the two groups. Result: The average ventilation time, LOS in CCU, and LOS in hospital for group I were 96.82 ± 19.46 hours, 10.91 ± 7.53 days, and 14.46 ± 7.58 days, respectively, and for group II, it was 85.14 ± 15.79 hours, 7.28 ± 3.68 days, and 10.21 ± 3.14 days, respectively, which was statistically significantly lower for group II. Reintubation, RV dysfunction, and hospital mortality were 16.3%, 37.2%, and 6.9% in group I, and 4.8%, 14.6%, and 2.4% in group II, respectively. The P value for each variable was significant < 0.05 (except mortality). Conclusion: Preoperative obstruction is a risk factor for postoperative obstruction, as 235 patients with obstructed TAPVC had severe PAH (39.98%) in this study. Management of severe PAH with a combination of milrinone and INO had a better outcome than milrinone alone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inhaled%20nitric%20oxide" title="inhaled nitric oxide">inhaled nitric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=milrinone" title=" milrinone"> milrinone</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20artery%20hypertension" title=" pulmonary artery hypertension"> pulmonary artery hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20anomalous%20pulmonary%20venous%20connection" title=" total anomalous pulmonary venous connection"> total anomalous pulmonary venous connection</a> </p> <a href="https://publications.waset.org/abstracts/191851/a-prospective-randomised-observational-study-of-obstructed-total-anamalous-pulmonary-venous-connection-tapvc-repair-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191851.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">21</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> Estimation of Particle Number and Mass Doses Inhaled in a Busy Street in Lublin, Poland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bernard%20Polednik">Bernard Polednik</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Piotrowicz"> Adam Piotrowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukasz%20Guz"> Lukasz Guz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzenna%20Dudzinska"> Marzenna Dudzinska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation is considered to be responsible for increased exposure of road users – i.e., drivers, car passengers, and pedestrians as well as inhabitants of houses located near roads - to pollutants emitted from vehicles. Accurate estimates are, however, difficult as exposure depends on many factors such as traffic intensity or type of fuel as well as the topography and the built-up area around the individual routes. The season and weather conditions are also of importance. In the case of inhabitants of houses located near roads, their exposure depends on the distance from the road, window tightness and other factors that decrease pollutant infiltration. This work reports the variations of particle concentrations along a selected road in Lublin, Poland. Their impact on the exposure for road users as well as for inhabitants of houses located near the road is also presented. Mobile and fixed-site measurements were carried out in peak (around 8 a.m. and 4 p.m.) and off-peak (12 a.m., 4 a.m., and 12 p.m.) traffic times in all 4 seasons. Fixed-site measurements were performed in 12 measurement points along the route. The number and mass concentration of particles was determined with the use of P-Trak model 8525, OPS 3330, DustTrak DRX model 8533 (TSI Inc. USA) and Grimm Aerosol Spectrometer 1.109 with Nano Sizer 1.321 (Grimm Aerosol Germany). The obtained results indicated that the highest concentrations of traffic-related pollution were measured near 4-way traffic intersections during peak hours in the autumn and winter. The highest average number concentration of ultrafine particles (PN0.1), and mass concentration of fine particles (PM2.5) in fixed-site measurements were obtained in the autumn and amounted to 23.6 ± 9.2×10³ pt/cm³ and 135.1 ± 11.3 µg/m³, respectively. The highest average number concentration of submicrometer particles (PN1) was measured in the winter and amounted to 68 ± 26.8×10³ pt/cm³. The estimated doses of particles deposited in the commuters’ and pedestrians’ lungs within an hour near 4-way TIs in peak hours in the summer amounted to 4.3 ± 3.3×10⁹ pt/h (PN0.1) and 2.9 ± 1.4 µg/h (PM2.5) and 3.9 ± 1.1×10⁹ pt/h (PN0.1) or 2.5 ± 0.4 µg/h (PM2.5), respectively. While estimating the doses inhaled by the inhabitants of premises located near the road one should take into account different fractional penetration of particles from outdoors to indoors. Such doses assessed for the autumn and winter are up to twice as high as the doses inhaled by commuters and pedestrians in the summer. In the winter traffic-related ultrafine particles account for over 70% of all ultrafine particles deposited in the pedestrians’ lungs. The share of traffic-related PM10 particles was estimated at approximately 33.5%. Concluding, the results of the particle concentration measurements along a road in Lublin indicated that the concentration is mainly affected by the traffic intensity and weather conditions. Further detailed research should focus on how the season and the metrological conditions affect concentration levels of traffic-related pollutants and the exposure of commuters and pedestrians as well as the inhabitants of houses located near traffic routes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20quality" title="air quality">air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition%20dose" title=" deposition dose"> deposition dose</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20effects" title=" health effects"> health effects</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20emissions" title=" vehicle emissions"> vehicle emissions</a> </p> <a href="https://publications.waset.org/abstracts/107260/estimation-of-particle-number-and-mass-doses-inhaled-in-a-busy-street-in-lublin-poland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107260.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">95</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> Extracellular Production of the Oncolytic Enzyme, Glutaminase Free L-Asparaginase, from Newly Isolated Streptomyces Olivaceus NEAE-119: Optimization of Culture Conditions Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20El-Ahmady%20El-Naggar">Noura El-Ahmady El-Naggar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among the antitumour drugs, bacterial enzyme L-asparaginase has been employed as the most effective chemotherapeutic agent in pediatric oncotherapy especially for acute lymphoblastic leukemia.

Hallenbeck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fuel reserve requirements due to depletion of fossil fuels have increased interest in biohydrogen since the 1990’s. In fermentative hydrogen production, pure, mixed, and co-cultures can be used to produce hydrogen. Several previous studies have evaluated hydrogen production by pure cultures of Clostridium butyricum or Enterobacter aerogenes. Evaluating hydrogen production by co-culture of these microorganisms is an interestıng approach since E. aerogenes is a facultative microorganism with resistance to oxygen in contrast to the strict anaerobe C. butyricum, and therefore has the ability to maintain anaerobic conditions. It was found that using co-cultures of facultative E. aerogenes (as a reducing agent and H2 producer) and the obligate anaerobe C. butyricum for producing hydrogen increases the yield of hydrogen by about 50% compared to C. butyricum by itself. Also, using different types of microorganisms for hydrogen production eliminates the need to use expensive reducing agents. C. butyricum strain pre-cultured anaerobically at 37 0C for 15h by inoculating 100 mL of GP medium (pH 6.8) consisting of 1% glucose, 2% polypeptone, 0.2% KH2PO4, 0.05% yeast extract, 0.05% MgSO4. 7H2O and E. aerogenes strain was pre-cultured aerobically at 30 0C, 150 rpm for 9 h by inoculating 100 mL of TGY medium (pH 6.8), consisting of 0.1% glucose, 0.5% tryptone, 0.1% K2HPO4, 0.5% yeast extract. All duplicate batch experiments were conducted in 100 mL bottles with different inoculum ratios of Clostridium butyricum and Enterobater aerogenes (C:E) using 5x diluted rich media (GP) consisting of 2 g/L glucose, 4g/L polypeptone, 0.4 g/L KH2PO4, 0.1 g/L yeast extract, 0.1 MgSO4.7H2O. The range of inoculum ratio of C. butyricum to E. aerogenes were 2:1,4:1,8:1, 1:2,1:4, 1:8, 1:0, 0:1. Using glucose as a carbon source aided in the observation of microbial behavior as well as making the effect of inoculum ratio more evident. Nearly all the glucose in the medium was used to produce hydrogen, except at a 1:0 ratio of inoculum (i.e. containing only C. butyricum). Low glucose consumption leads to a higher hydrogen yield due to cumulative hydrogen production and consumption of glucose, but not as much as C:E, 8:1. The lowest hydrogen yield was achieved in 1:8 inoculum ratio of C:E, 71.9 mL, 1.007±0.01 mol H2/mol glucose and the highest cumulative hydrogen, hydrogen yield and dry cell weight were achieved in 8:1 inoculum ratio of C:E, 117.4 mL, 2.035±0.082 mol H2/mol glucose, 0.4 g/L respectively. In this study effect of inoculum ratio on dark fermentative biohydrogen production using C. butyricum and E. aerogenes was investigated. The maximum hydrogen yield of 2.035mol H2/mol glucose was obtained using 2g/L glucose, an initial pH of 6 and an inoculum ratio of C. butyricum to E. aerogenes of 8:1. Results showed that inoculum ratio is an important parameter on hydrogen production due to competition between the two microorganisms in using substrate for growth and production of by-products. The results presented here could be of great significance for further waste management studies using co-culture hydrogen production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biohydrogen" title="biohydrogen">biohydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=Clostridium%20butyricum" title=" Clostridium butyricum"> Clostridium butyricum</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20fermentation" title=" dark fermentation"> dark fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=Enterobacter%20aerogenes" title=" Enterobacter aerogenes"> Enterobacter aerogenes</a>, <a href="https://publications.waset.org/abstracts/search?q=inoculum%20ratio%20in%20biohydrogen%20production" title=" inoculum ratio in biohydrogen production"> inoculum ratio in biohydrogen production</a> </p> <a href="https://publications.waset.org/abstracts/47191/effect-of-inoculum-ratio-on-dark-fermentative-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47191.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">236</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">41</span> Culture Medium Design Based on Whey for the Growth and Bacteriocin Production of Strains of Pediococcus pentosaceus </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Gutierrez-Cortes">Carolina Gutierrez-Cortes</a>, <a href="https://publications.waset.org/abstracts/search?q=Hector%20Suarez"> Hector Suarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Gustavo%20Buitrago"> Gustavo Buitrago</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacteriocins are antimicrobial peptides produced by bacteria as a competitive strategy for substrate and habitat. Those peptides have a potential use as food biopreservatives due to their antimicrobial activity against foodborne pathogens, avoiding the use of additives that can be harmful to consumers. The industrial production of bacteriocins is currently expensive; one of the options to be competitive is the development of economic culture media, for example, with the use of agro-industrial wastes such as whey. This study evaluated the growth and production of bacteriocins from four strains: Pediococcus pentosaceus 63, Pediococcus pentosaceus 145, Pediococcus pentosaceus 146 and Pediococcus pentosaceus 147 isolated from ‘minas cheese’ (artisanal cheese made from raw milk in the state of Minas Gerais, Brazil) in order to select a strain with growth at high rates and higher antimicrobial activity against Listeria monocytogenes 104 after incubation on the culture medium designed with whey and other components. The media used were: MRS broth, modified MRS broth (using different sources of carbon and nitrogen and different amounts of micronutrients) and a culture medium designed by a factorial design using whey and other components. The final biomass concentrations of the four strains in MRS broth after 24 hours of incubation were very similar 9.25, 9.33, 9.25 and 9.22 (log CFU/mL) for P. pentosaceus 63, P. pentosaceus 145, P. pentosaceus 146 and P. pentosaceus 147 respectively. In the same assays, antimicrobial activity of 3200 AU/mL for the first three and of 12800 AU/mL for P. pentosaceus 147 were obtained. Culture of P. pentosaceus 63 on modified MRS broth, showed the effect of some sources of carbon on the activity of bacteriocin, obtaining 12800 AU/mL with dextrose and 25600 AU/mL with maltose. Cultures of P. pentosaceus 145, 146 and 147 with these same sugars presented activity of 12800 AU/mL. It was observed that the modified MRS medium using whey increased the antimicrobial activity of the strains at 16000, 6400, 16000 and 19200 AU/mL for each strain respectively, keeping the biomass at values close to 9 log units. About nitrogen sources, it was observed that the combination of peptone (10 g /L), meat extract (10 g/L) and yeast extract (5 g/L) promoted the highest activity (12800 AU/mL), and in all cases MgSO4, MnSO4, K2HPO4 and ammonium citrate at low concentrations adversely affected bacteriocin production. Because P. pentosaceus 147 showed the highest antimicrobial activity in the presence of whey, it was used to evaluate the culture medium (peptone (10 g/L), meat extract (8 g/L), yeast extract (2 g/L), Tween® 80 (1 g/L), ammonium citrate (2 g/L), sodium acetate (5 g/L), MgSO4 (0.2 g/L), MnSO4 (0.04 g/L)). With the designed medium added with whey, 9.34 log units of biomass concentration and 19200 AU/mL were achieved for P. pentosaceus 147. The above suggest that the new medium promotes the antimicrobial activity of P. pentosaceus 147 allowing the use of an economic medium using whey. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title="antimicrobial activity">antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteriocins" title=" bacteriocins"> bacteriocins</a>, <a href="https://publications.waset.org/abstracts/search?q=pediococcus" title=" pediococcus"> pediococcus</a>, <a href="https://publications.waset.org/abstracts/search?q=whey" title=" whey"> whey</a> </p> <a href="https://publications.waset.org/abstracts/75800/culture-medium-design-based-on-whey-for-the-growth-and-bacteriocin-production-of-strains-of-pediococcus-pentosaceus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75800.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">226</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> Lead in The Blood and Hypertension in Indonesia: A Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ainia%20Nurul%20Aqida">Ainia Nurul Aqida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lead is one of the sources of air pollution.

Sowing was realized in plastic pots containing sandy substrates of bentonite 0, 3, 5, 7, and 10% associated with abiotic stresses of salinity corresponding to doses of NaCl, MgCl2 and MgSO4 20, 40, and 60 mmol/l respectively. The purpose of this work is to study the combined effect of salinity and of bentonite on a plant commonly cultivated in Algeria the broad bean Vicia faba has through the chemical and hydrous parameter. The results show that the combined action of strong concentration salt (40 and 60 mmol/l) and of bentonite a reduction of the relative content water reveals, against an increase in the content of hydrous deficit and of sodium. The growth of broad bean is significant in the substrate amended to 5 % of bentonite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salinity" title="salinity">salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=bentonite" title=" bentonite"> bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=Vicia%20faba%20L" title=" Vicia faba L"> Vicia faba L</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20content" title=" sodium content"> sodium content</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrous%20parameters" title=" hydrous parameters"> hydrous parameters</a> </p> <a href="https://publications.waset.org/abstracts/31285/the-effect-of-salinity-and-bentonite-on-the-hydrous-behaviors-and-sodium-content-of-the-broad-bean-vicia-faba-var-semilla-violeta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31285.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">367</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> Adjuvant Effect and Mineral Addition in Aggressive Environments on the Sustainability of Using Local Materials Concretes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Belouadah">M.

Thus, the durability of concrete depends on a variety of material characteristics, but also the aggressiveness of the environment. Much durability problems encountered in tropical regions (region M'sila) due to the presence of chlorides and sulfates (in the ground or in the aggregate) with the additional aggravation of the effect of hot weather and arid. This lack of sustainability has a direct influence on the structure of the building and can lead to the complete deterioration of many buildings. The characteristics of the nature of fillers are evaluated based on the degree of aggressiveness of the environment considering as a means of characterization: mechanical strength, porosity. Specimens will be exposed to different storage media chemically aggressive drinking water, salts and sulfates (sodium chloride, MgSO4), solutions are not renewed or PH control solutions. The parameters taken into account are: age, the nature and degree of aggressiveness of the environment conservation, the incorporation of adjuvant type superplasticizer dosage and mineral additives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ordinary%20concretes" title="ordinary concretes">ordinary concretes</a>, <a href="https://publications.waset.org/abstracts/search?q=marble%20powder%20fillers" title=" marble powder fillers"> marble powder fillers</a>, <a href="https://publications.waset.org/abstracts/search?q=adjuvant" title=" adjuvant"> adjuvant</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/28719/adjuvant-effect-and-mineral-addition-in-aggressive-environments-on-the-sustainability-of-using-local-materials-concretes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28719.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">274</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> Statistical Optimization of Vanillin Production by Pycnoporus Cinnabarinus 1181</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swarali%20Hingse">Swarali Hingse</a>, <a href="https://publications.waset.org/abstracts/search?q=Shraddha%20Digole"> Shraddha Digole</a>, <a href="https://publications.waset.org/abstracts/search?q=Uday%20Annapure"> Uday Annapure</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study investigates the biotransformation of ferulic acid to vanillin by Pycnoporus cinnabarinus and its optimization using one-factor-at-a-time method as well as statistical approach.

Screening of the significant factors was carried out using L25 Taguchi orthogonal array and then these selected significant factors were further optimized using response surface methodology (RSM). Significant media components obtained using Taguchi L25 orthogonal array were glucose, KH2PO4 and yeast extract. Further, a Box Behnken design was used to investigate the interactive effects of the three most significant media components. The final medium obtained after optimization using RSM containing glucose (34.89 g/L), diammonium tartrate (1 g/L), yeast extract (1.47 g/L), MgSO4•7H2O (0.5 g/L), KH2PO4 (0.15 g/L), and CaCl2•2H2O (20 mg/L) resulted in amplification of vanillin production from 30.88 mg/L to 187.63 mg/L. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferulic%20acid" title="ferulic acid">ferulic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=pycnoporus%20cinnabarinus" title=" pycnoporus cinnabarinus"> pycnoporus cinnabarinus</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=vanillin" title=" vanillin"> vanillin</a> </p> <a href="https://publications.waset.org/abstracts/20013/statistical-optimization-of-vanillin-production-by-pycnoporus-cinnabarinus-1181" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20013.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Partnering With Key Stakeholders for Successful Implementation of Inhaled Analgesia for Specific Emergency Department Presentations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Hazelwood">Sarah Hazelwood</a>, <a href="https://publications.waset.org/abstracts/search?q=Janice%20Hay"> Janice Hay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Methoxyflurane is an inhaled analgesic administered via a disposable inhaler, which has been used in Australia for 40 years for the management of pain in children & adults. However, there is a lack of data for methoxyflurane as a frontline analgesic medication within the emergency department (ED). This study will investigate the usefulness of methoxyflurane in a private inner-city ED. The study concluded that the inclusion of all key stakeholders in the prescribing, administering & use of this new process led to comprehensive uptake & vastly positive outcomes for consumer & health professionals. Method: A 12-week prospective pilot study was completed utilizing patients presenting to the ED in pain (numeric pain rating score > 4) that fit the requirement of methoxyflurane use (as outlined in the Australian Prescriber information package). Nurses completed a formatted spreadsheet for each interaction where methoxyflurane was used. Patient demographics, day, time, initial numeric pain score, analgesic response time, the reason for use, staff concern (free text), & patient feedback (free text), & discharge time was documented. When clinical concern was raised, the researcher retrieved & reviewed patient notes. Results: 140 methoxyflurane inhalers were used. 60% of patients were 31 years of age & over (n=82) with 16% aged 70+. The gender split; 51% male: 49% female. Trauma-related pain (57%) saw the highest use of administration, with the evening hours (1500-2259) seeing the greatest numbers used (39%). Tuesday, Thursday & Sunday shared the highest daily use throughout the study. A minimum numerical pain score of 4/10 (n=13, 9%), with the ranges of 5 - 7/10 (moderate pain) being given by almost 50% of patients. Only 3 instances of pain scores increased post use of methoxyflurane (all other entries showed pain score < initial rating). Patients & staff noted obvious analgesic response within 3 minutes (n= 96, 81%, of administration). Nurses documented a change in patient vital signs for 4 of the 15 patient-related concerns; the remaining concerns were due to “gagging” on the taste, or “having a coughing episode”; one patient tried to leave the department before the procedure was attended (very euphoric state). Upon review of the staff concerns – no adverse events occurred & return to therapeutic vitals occurred within 10 minutes. Length of stay for patients was compared with similar presentations (such as dislocated shoulder or ankle fracture) & saw an average 40-minute decrease in time to discharge. Methoxyflurane treatment was rated “positively” by > 80% of patients – with remaining feedback related to mild & transient concerns. Staff similarly noted a positive response to methoxyflurane as an analgesic & as an added tool for frontline analgesic purposes. Conclusion: Methoxyflurane should be used on suitable patient presentations requiring immediate, short term pain relief. As a highly portable, non-narcotic avenue to treat pain this study showed obvious therapeutic benefit, positive feedback, & a shorter length of stay in the ED. By partnering with key stake holders, this study determined methoxyflurane use decreased work load, decreased wait time to analgesia, and increased patient satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analgesia" title="analgesia">analgesia</a>, <a href="https://publications.waset.org/abstracts/search?q=benefits" title=" benefits"> benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency" title=" emergency"> emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=methoxyflurane" title=" methoxyflurane"> methoxyflurane</a> </p> <a href="https://publications.waset.org/abstracts/130494/partnering-with-key-stakeholders-for-successful-implementation-of-inhaled-analgesia-for-specific-emergency-department-presentations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130494.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">123</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> Obstructive Bronchitis and Pneumonia by a Mixed Infection of HPIV- 3, S. pneumoniae in an Immunocompromised 10M Infant: Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Smilevska%20Spasova">Olga Smilevska Spasova</a>, <a href="https://publications.waset.org/abstracts/search?q=Katerina%20Boshkovska"> Katerina Boshkovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Gorica%20Popova"> Gorica Popova</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirjana%20Popovska"> Mirjana Popovska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Pneumonia is an infection of the pulmonary parenchyma. HPIV 3 is one of four viruses that is a member of the Paramyxoviridae family designated types 1-4 that have a nonsegmented, single-stranded RNA genome with a lipid-containing envelope. They are spread from the respiratory tract by aerosolized secretions or by direct contact with secretions. Type 3 is endemic and can cause serious illness in immunocompromised patients. Illness caused by parainfluenza occurs shortly after inoculation with the virus. The level of immunoglobulin A antibody in serum is the best predictor of susceptibility to infection. Streptococcus pneumonia or pneumococcus is a Gram-positive, spherical bacteria, usually found in pairs and it is a member of the genus Streptococcus. Streptococcus pneumonia resides asymptomatically in healthy carriers typically colonizing the respiratory tract, sinuses, and nasal cavity. In individuals with weaker immune systems like young infants, pneumococcal bacterium is the most common cause of community-acquired pneumonia in the world. Case Report: The aim is to present a case of lower respiratory tract infection in an infant caused by parainfluenza virus 3, S. pneumonia and undifferentiated gram-negative bacteria that was successfully treated. The infant is with a history of recurrent episodes of wheezing in the past 3mounts.Infant of 10months presents 2weeks before admittance with high fever, runny nose, and cough. The primary pediatrician prescribed oral cefpodoxime for 10days and inhaled salbutamol. Two days before admittance in hospital the infant with high fever, cough, and difficulty breathing. At admittance, infant is pale, anxious with rapid respirations, cough, wheezing and tachycardia. On auscultation: vesicular breathing sounds with high pitched wheezing and on the right coarse crackles. Investigations: Blood analysis: RBC: 4, 7 x1012L, WBC: 8,3x109L: Neut: 42.73% Lym: 41.57%, Hgb: 9.38 g/dl MCV: 62.7fl, MCH: 20.0pg MCHC: 31.8 g/dl RDW: 18.7% Plt-307.9 x109LCRP: 2,5mg/l, serum iron-7.92umol/l, O2sat-97% on blood gas analysis, puls-125/min.X-ray of chest with hyperinflationand right pericardial consolidation. Microbiological analysis of sputum sample is positive for undifferentiated gram-negative bacteria (colonizer)–resistant to cefotaxime, ampicillin, cefoxitin, sulfamet.+trimetoprim and sensitive to amikacin, gentamicin, and ciprofloxacin. Molecular multiplex RT-PCR for 19 viruses and multiplex PCR for 7 bacteria test for respiratory pathogens positive for Parainfluenza virus 3(Ct=22.73), Streptococcus pneumonia (Ct=26.75).IED: IgG-9.31g/l, IgA-0.351g/l, IgM-0.86g/l. Therapy: Treatment was started with inhaled salbutamol, intravenous antibiotic cefotaxime as well as systemic corticosteroids. On day 7 because of slow clinical resolution of chest auscultation findings and an etiologic clue with a positive sputum sample for resistant undifferentiated gram negative bacteria, a second intravenous antibiotic was administered amikacin. The infant is discharged on day 14 with resolution of clinical findings. Conclusion: Mixed co-infections with respiratory viruses and bacteria in immunocompromised infants are likely to lead to a more severe form of community acquired pneumonia that will need hospitalization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPIV-%203" title="HPIV- 3">HPIV- 3</a>, <a href="https://publications.waset.org/abstracts/search?q=infant" title=" infant"> infant</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumonia" title=" pneumonia"> pneumonia</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20pneumonia" title=" S. pneumonia"> S. pneumonia</a>, <a href="https://publications.waset.org/abstracts/search?q=x-ray%20chest" title=" x-ray chest"> x-ray chest</a> </p> <a href="https://publications.waset.org/abstracts/149986/obstructive-bronchitis-and-pneumonia-by-a-mixed-infection-of-hpiv-3-s-pneumoniae-in-an-immunocompromised-10m-infant-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Quality of Care for the Maternal Complications at Selected Primary and Secondary Health Facilities of Bangladesh: Lessons Learned from a Formative Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohiuddin%20Ahsanul%20Kabir%20Chowdhury">Mohiuddin Ahsanul Kabir Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafisa%20Lira%20Huq"> Nafisa Lira Huq</a>, <a href="https://publications.waset.org/abstracts/search?q=Afroza%20Khanom"> Afroza Khanom</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiqul%20Islam"> Rafiqul Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Nurus%20Salam%20Khan"> Abdullah Nurus Salam Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhana%20Karim"> Farhana Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Zaka"> Nabila Zaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Shams%20El%20Arifeen"> Shams El Arifeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Sk.%20Masum%20Billah"> Sk.

Aversion of deaths from maternal complication by ensuring quality health care could be an important path to accelerate the rate of reduction of MMR. This formative research was aimed at exploring the provision of quality maternal health services at different level of health facilities. The study was conducted in 1 district hospital (DH) and 4 Upazila health complexes (UHC) of Kurigram district of Bangladesh, utilizing both quantitative and qualitative research methods. We conducted 14 key informant interviews with facility managers and 20 in-depth interviews with health care providers and support staff. Besides, we observed 387 normal deliveries from which we found 17 cases of post partum haemorrhage (PPH) and 2 cases of eclampsia during the data collection period extended from July-September 2016. The quantitative data were analyzed by using descriptive statistics, and the qualitative component underwent thematic analysis with the broad themes of facility readiness for maternal complication management, and management of complications. Inadequacy in human resources has been identified as the most important bottleneck to provide quality care to manage maternal complications. The DH had a particular paucity of human resources in medical officer cadre where about 61% posts were unfilled. On the other hand, in the UHCs the positions mostly empty were obstetricians (75%, paediatricians (75%), staff nurses (65%), and anaesthetists (100%). The workload on the existing staff is increased because of the persistence of vacant posts. Unavailability of anesthetists and consultants does not permit the health care providers (HCP) of lower cadres to perform emergency operative procedures and forces them to refer the patients although referral system is not well organized in rural Bangladesh. Insufficient bed capacity, inadequate training, shortage of emergency medicines etc. are other hindrance factors for facility readiness. Among the 387 observed delivery case, 17 (4.4%) were identified as PPH cases, and only 2 cases were found as eclampsia/pre-eclampsia. The majority of the patients were treated with uterine message (16 out of 17, 94.1%) and injectable Oxytocin (14 out of 17, 82.4%). The providers of DH mentioned that they can manage the PPH because of having provision for diagnostic and blood transfusion services, although not as 24/7 services. Regarding management of eclampsia/pre-eclampsia, HCPs provided Diazepam, MgSO4, and other anti-hypertensives. The UHCs did not have MgSO4 at stock even, and one facility manager admitted that they treat eclampsia with Diazepam only. The nurses of the UHCs were found to be afraid to handle eclampsia cases. The upcoming interventions must ensure refresher training of service providers, continuous availability of essential medicine and equipment needed for complication management, availability of skilled health workforce, availability of functioning blood transfusion unit and pairing of consultants and anaesthetists to reach the newly set targets altogether. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title="Bangladesh">Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20facilities" title=" health facilities"> health facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=maternal%20complications" title=" maternal complications"> maternal complications</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20care" title=" quality of care"> quality of care</a> </p> <a href="https://publications.waset.org/abstracts/80997/quality-of-care-for-the-maternal-complications-at-selected-primary-and-secondary-health-facilities-of-bangladesh-lessons-learned-from-a-formative-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80997.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">235</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> Performance of an Anaerobic Osmotic Membrane Bioreactor Hybrid System for Wastewater Treatment and Phosphorus Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming-Yeh%20Lu">Ming-Yeh Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiao-Shing%20Chen"> Shiao-Shing Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Saikat%20Sinha%20Ray"> Saikat Sinha Ray</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Te%20Hsu"> Hung-Te Hsu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The submerged anaerobic osmotic membrane bioreactor (AnOMBR) integrated with periodic microfiltration (MF) extraction for simultaneous phosphorus and clean water recovery from wastewater was evaluated. A laboratory-scale AnOMBR used cellulose triacetate (CTA) membranes with effective membrane area of 130 cm² was fully submerged into a 5 L bioreactor at 30-35 ℃. Active layer was orientated to feed stream for minimizing membrane fouling and scaling. Additionally, a peristaltic pump was used to circulate magnesium sulphate (MgSO₄) solution applied as draw solution (DS). Microfiltration membrane periodically extracted about 1 L solution when the TDS reaches to 5 g/L to recover phosphorus and simultaneously control the salt accumulation in the bioreactor. During experiment progress, the average water flux was around 1.6 LMH. The AnOMBR process showed greater than 95% removal of soluble chemical oxygen demand (sCOD), nearly 100% of total phosphorous whereas only partial of ammonia was removed. On the other hand, the average methane production of 0.22 L/g sCOD was obtained. Subsequently, the overall performance demonstrates that a novel submerged AnOMBR system is potential for simultaneous wastewater treatment and resource recovery from wastewater. Therefore, the new concept of this system can be used to replace for the conventional AnMBR in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20treatment" title="anaerobic treatment">anaerobic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20osmosis" title=" forward osmosis"> forward osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus%20recovery" title=" phosphorus recovery"> phosphorus recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20bioreactor" title=" membrane bioreactor"> membrane bioreactor</a> </p> <a href="https://publications.waset.org/abstracts/63831/performance-of-an-anaerobic-osmotic-membrane-bioreactor-hybrid-system-for-wastewater-treatment-and-phosphorus-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63831.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">236</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> Parental Perceptions and Practices toward Childhood Asthma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20K.%20Abu-Shaheen">Amani K.

Objective: To identify the prevalence of asthma and to investigate the perceptions and practices of parents toward asthma and its management in Saudi children. Methods: A two-stage cross-sectional survey of 2000 parents of children aged 3–15 years from schools located in all five districts of Riyadh province located in central Saudi Arabia, was conducted. Data collection was accomplished using a self-administered questionnaire based on information obtained from the literature. Results: Of 1450 children whose parents participated in the study, 600 had asthma, dyspnea, or chest allergy. The overall number of children with parental reports of ever having been diagnosed with asthma was 478 (32.9%). The majority of parents (321, 53.5%) believed that asthma was a hereditary disease. Of these parents, 361 (60.3%) were concerned about side effects of inhaled steroids, and 192 (32%) about development of dependency on asthma medications. Three hundred sixty seven (61.2%) parents reported that they could treat the asthma attack at home and almost 76% of parents went to pediatric emergency department during asthma attack. Conclusions: In this study, the overall prevalence of children whose parents reported that they were diagnosed with asthma was high (32.9%). Furthermore, parents of children with asthma had misperceptions regarding asthma and exhibited ineffective practices in its management. To improve asthma care and compliance, adequate education should be provided to parents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asthma" title="asthma">asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=parents" title=" parents"> parents</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/45901/parental-perceptions-and-practices-toward-childhood-asthma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45901.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">274</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> Improved Production, Purification and Characterization of Invertase from Penicillium lilacinum by Shaken Flask Technique of Submerged Fermentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kashif%20Ahmed">Kashif Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent years researchers have been motivated towards extensive exploring of living organism, which could be utilized effectively in intense industrial conditions. The present study shows enhanced production, purification and characterization of industrial enzyme, invertase (Beta-D-fructofuranosidase) from Penicillium lilacinum. Various agricultural based by-products (cotton stalk, sunflower waste, rice husk, molasses and date syrup) were used as energy source. The highest amount of enzyme (13.05 Units/mL) was produced when the strain was cultured on growth medium containing date syrup as energy source. Yeast extract was used as nitrogen source after 96 h of incubation at incubation temperature of 40º C. Initial pH of medium was 8.0, inoculum size 6x10⁶ conidia and 200 rev/min agitation rate. The enzyme was also purified (7 folds than crude) and characterized. Molecular mass of purified enzyme (65 kDa) was determined by 10 % SDS-PAGE. Lineweaver-Burk Plot was used to determine Kinetic constants (Vmax 178.6 U/mL/min and Km 2.76 mM). Temperature and pH optima were 55º C and 5.5 respectively. MnCl₂ (52.9 %), MgSO₄ (48.9 %), BaCl₂ (24.6 %), MgCl₂ (9.6 %), CoCl₂ (5.7 %) and NaCl (4.2 %) enhanced the relative activity of enzyme and HgCl₂ (-92.8 %), CuSO₄ (-80.2 %) and CuCl₂ (-76.6 %) were proved inhibitors. The strain was showing enzyme activity even at extreme conditions of temperature (up to 60º C) and pH (up to 9), so it can be used in industries. <p class="card-text"><strong>Keywords:</strong> <a
