The study group comprised 50 patients with the diagnosis of PD who have applied to Gaziantep University Faculty of Medicine, and Department of Neurology. 50 healthy individuals without any neuro degenerative disease are included as controls. Ribonucleic acid (RNA) was obtained from blood samples of patient and control groups. Complementary deoxyribonucleic acid (cDNA) was obtained from RNA samples using reverse transcription polymerase chain reaction (RT-PCR) technique. The gene expression of NFKB1*1 in patient/control groups were observed to decrease significantly, and the differences between groups with the Mann-Whitney method within 95% confidence interval (p<0.05) were analyzed. This salient finding provide a clue for our hypothesis that reduced activity of NFKB1*1 gene might play a role, at least partly, in the pathophysiology of PD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parkinson%E2%80%99s%20Disease" title="Parkinson鈥檚 Disease">Parkinson鈥檚 Disease</a>, <a href="https://publications.waset.org/abstracts/search?q=NFKB1" title=" NFKB1"> NFKB1</a>, <a href="https://publications.waset.org/abstracts/search?q=mRNA%20expression" title=" mRNA expression"> mRNA expression</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a> </p> <a href="https://publications.waset.org/abstracts/20248/mrna-expression-of-nfkb1-with-parkinsons-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20248.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">502</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">3338</span> Acceleration of DNA Hybridization Using Electroosmotic Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yun-Hsiang%20Wang">Yun-Hsiang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huai-Yi%20Chen"> Huai-Yi Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Kin%20Fong%20Lei"> Kin Fong Lei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deoxyribonucleic acid (DNA) hybridization is a common technique used in genetic assay widely.

Here, microfluidic electrode platform producing electroosmosis generated by alternating current signal has been proposed to enhance the hybridization ratio and rate. The electrode was made of aurum fabricated by microfabrication technique. Thiol-modified oligo probe was immobilized on the electrode for specific capture of target, which is modified by fluorescent tag.

Resulting optical changes for illuminated DNA were investigated using UV-Vis spectra and photoluminescent. Optical properties show potential application in sensors based on modified DNA. Then selected DNA-surfactant complexes were illuminated with electromagnetic radiation for 5h. Molecular structure, optical characteristic were examinated for obtained complexes.

The present study deals with the preparation of sunflower oil from commercial seed sample which was obtained from local market. The physicochemical properties of the oil were determined which included saponification value, acid value and ester value. Results showed that saponification value of the oil was 191.675, acid value was 0.64 and ester value to be 191.035 for the sample under observation. GC-MS analysis of sunflower oil was carried out to check its composition. Oleic acid was determined with linoleic acid and isopropyl palmitate. It represents the presence of three major components of sunflower oil. Other compounds detected were, p-toluylic acid, butylated hydroxytoluene, 1,2-benzenedicarboxylic acid, benzoic acid, 2,4,6-trimethyl-, 2,4,6-trimethylphenyl ester and 2,4-decadienal, (E,E). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title="GC-MS">GC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=oleic%20acid" title=" oleic acid"> oleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=saponification%20value" title=" saponification value"> saponification value</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower%20oil" title=" sunflower oil"> sunflower oil</a> </p> <a href="https://publications.waset.org/abstracts/42725/characterization-of-sunflower-oil-for-illustration-of-its-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42725.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">318</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">3334</span> An in Situ Dna Content Detection Enabled by Organic Long-persistent Luminescence Materials with Tunable Afterglow-time in Water and Air</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Desissa%20Yadeta%20Muleta">Desissa Yadeta Muleta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purely organic long-persistent luminescence materials (OLPLMs) have been developed as emerging organic materials due to their simple production process, low preparation cost and better biocompatibilities. Notably, OLPLMs with afterglow-time-tunable long-persistent luminescence (LPL) characteristics enable higher-level protection applications and have great prospects in biological applications. The realization of these advanced performances depends on our ability to gradually tune LPL duration under ambient conditions, however, the strategies to achieve this are few due to the lack of unambiguous mechanisms. Here, we propose a two-step strategy to gradually tune LPL duration of OLPLMs over a wide range of seconds in water and air, by using derivatives as the guest and introducing a third-party material into the host-immobilized host鈥揼uest doping system. Based on this strategy, we develop an analysis method for deoxyribonucleic acid (DNA) content detection without DNA separation in aqueous samples, which circumvents the influence of the chromophore, fluorophore and other interferents in vivo, enabling a certain degree of in situ detection that is difficult to achieve using today鈥檚 methods. This work will expedite the development of afterglow-time-tunable OLPLMs and expand new horizons for their applications in data protection, bio-detection, and bio-sensing <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deoxyribonucliec%20acid" title="deoxyribonucliec acid">deoxyribonucliec acid</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20persistent%20luminescent%20materials" title=" long persistent luminescent materials"> long persistent luminescent materials</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=air" title=" air"> air</a> </p> <a href="https://publications.waset.org/abstracts/161914/an-in-situ-dna-content-detection-enabled-by-organic-long-persistent-luminescence-materials-with-tunable-afterglow-time-in-water-and-air" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161914.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">76</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">3333</span> Comparison of Punicic Acid Amounts in Abdominal Fat Farm Feeding Hy-Line Chickens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozcan%20Baris%20Citil">Ozcan Baris Citil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Akoz"> Mehmet Akoz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effects of fatty acid composition and punicic acid contents of abdominal fat of Hy-line hens were investigated by the gas chromatographic method.

Garden snails (Helix aspersa) were picked up by hand from the Central Anatolia Region of Turkey, in autumn (November) in 2015. Fatty acid methyl esters (FAMEs) and cholesterol analysis were analyzed by gas chromatography (GC). The protein contents of snail muscle were determined with Kjeldahl distillation units. Statistical comparisons were made by using SPSS Software (version 16.0). Thirty different fatty acids of different saturation levels were detected. As the predominant fatty acids, stearic acid (C18:0), oleic acid (C18:1蠅9), linoleic acid (C18:2蠅6), palmitic acid (C16:0), arachidonic acid (C20:4蠅6), eicosadienoic acid (C20:2) and linolenic acid (C18:3蠅3) were found in Helix aspersa. Palmitic acid (C16:0) was identified as the major SFA in autumn. Linoleic acid (C18:2蠅6), eicosadienoic acid (C20:2) and arachidonic acid (C20:4蠅6) have the highest levels among the PUFAs. In the present study, 蠅3 were found 5.48% in autumn. Linolenic acid and omega-3 fatty acid amounts in the autumn decreased significantly but cholesterol content was not affected in Helix aspersa in autumn (November) in 2015. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helix%20aspersa" title="Helix aspersa">Helix aspersa</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title=" fatty acid"> fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=SFA" title=" SFA"> SFA</a>, <a href="https://publications.waset.org/abstracts/search?q=PUFA" title=" PUFA"> PUFA</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a> </p> <a href="https://publications.waset.org/abstracts/47347/proximate-analysis-of-muscle-of-helix-aspersa-living-in-konya-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47347.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">338</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">3331</span> Cardioprotective Effect of Oleanolic Acid and Urosolic Acid against Doxorubicin-Induced Cardiotoxicity in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sameer%20N.%20Goyal">Sameer N.

The aim of the study is to evaluate intravenously administered oleanolic acid and ursolic acid in doxorubicin induced cardiotoxicity. Cardiotoxicity was induced in albino wistar rat with single intravenous injection of doxorubicin at dose of 67.75mg/kg i.v for 48 hrs at 12 hrs interval following doxorubicin administration in the same model cardioprotective effect of amifostine (90 mg/kg i.v, single dose prior 30 min before doxorubicin administration) was evaluated as standard treatment. Induction of cardiotoxicity was confirmed by rise in cardiac markers in serum such as CK鈥揗B, LDH and also by electrocardiographically. The doxorubicin treated group significantly increased in QT interval, serum CK-MB, serum LDH, SGOT, SGPT and antioxidant parameter. Both the treatment group showed significant protective effect on Hemodynamic, electrocardiographic, biochemical, and antioxidant parameters. The oleanolic acid showed slight protective effect in histological lesions in doxorubicin induced cardiotoxicity. Hence, the results indicate that Oleanolic acid has more cardioprotective potential than ursolic acid against doxorubicin induced cardiotoxicity in rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardioprotection" title="cardioprotection">cardioprotection</a>, <a href="https://publications.waset.org/abstracts/search?q=doxorubicin" title=" doxorubicin"> doxorubicin</a>, <a href="https://publications.waset.org/abstracts/search?q=oleanolic%20acid" title=" oleanolic acid"> oleanolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=ursolic%20acid" title=" ursolic acid"> ursolic acid</a> </p> <a href="https://publications.waset.org/abstracts/23229/cardioprotective-effect-of-oleanolic-acid-and-urosolic-acid-against-doxorubicin-induced-cardiotoxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23229.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">528</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">3330</span> The Catalytic Properties of PtSn/Al2O3 for Acetic Acid Hydrogenation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mingchuan%20Zhou">Mingchuan Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Haitao%20Zhang"> Haitao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongfang%20Ma"> Hongfang Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiyong%20Ying"> Weiyong Ying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alumina supported platinum and tin catalysts with different loadings of Pt and Sn were prepared and characterized by low temperature N<sub>2</sub> adsorption/desorption, H<sub>2</sub>-temperature programed reduction and CO pulse chemisorption.

This biological model is an effective tool for the detection of endocrine disruptors because it responds well to the main agonist of the androgen receptor (testosterone) and also to an antagonist: flutamide. The cytotoxicity of each chemical compound tested was measured using an MTT assay (tetrazolium salt, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) which measures the activity of the reductase function of mitochondrial succinate dehydrogenase enzymes of cultured cells. This complementary cytotoxicity test is essential to ensure that the effects of reduction in luminescence intensity observed during androgenic tests are only attributable to the anti-androgenic action of the compounds tested and not to their possible cytotoxic properties. Tests of the androgenic activity of antifungals show that these compounds do not have the capacity to induce transcription of the luciferase gene. These compounds do not exert an androgenic effect on MDA-Kb2 cells in culture for the environmental concentrations tested. The addition of flutamide for the same tested concentrations of antifungal molecules reduces the luminescence induced by amphotericin B, econazole and miconazole, which is explained by a strong interaction of these molecules with flutamide which may have a greater toxic effect than when tested alone. The cytotoxicity test shows that econazole and ketoconazole can cause cell death at certain concentrations tested. This cell mortality is perhaps induced by a direct or indirect action on deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or proteins necessary for cell division. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title="cytotoxicity">cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=androgenic%20potential" title=" androgenic potential"> androgenic potential</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungals" title=" antifungals"> antifungals</a>, <a href="https://publications.waset.org/abstracts/search?q=MDA-Kb2" title=" MDA-Kb2"> MDA-Kb2</a> </p> <a href="https://publications.waset.org/abstracts/186088/cytotoxicity-and-androgenic-potential-of-antifungal-drug-substances-on-mda-kb2-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186088.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">48</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">3328</span> Fatty Acid Composition and Therapeutic Effects of Beebread</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sibel%20Silici">Sibel Silici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Palynological spectrum, proximate and fatty acids composition of eight beebread samples obtained from different geographical origins were determined.

To be used as materials for biofuel production, it needs pretreatment process to improve efficiency of hydrolysis. In this work, chemical pretreatments on rice straw using three diluted organic acids, including acetic acid, citric acid, oxalic acid, were optimized. Using Response Surface Methodology (RSM), the effect of three pretreatment parameters, acid concentration, treatment time, and reaction temperature, on pretreatment efficiency were statistically evaluated. The results indicated that dilute oxalic acid pretreatment led to the highest enhancement of enzymatic saccharification by commercial cellulase and yielded sugar up to 10.67 mg/ml when using 5.04% oxalic acid at 137.11 oC for 30.01 min. Compared to other acid pretreatment by acetic acid, citric acid, and hydrochloric acid, the maximum sugar yields are 7.07, 6.30, and 8.53 mg/ml, respectively. Here, it was demonstrated that organic acids can be used for pretreatment of lignocellulosic materials to enhance of hydrolysis process, which could be integrated to other applications for various biorefinery processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lignocellolusic%20biomass" title="lignocellolusic biomass">lignocellolusic biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=pretreatment" title=" pretreatment"> pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20acid%20response%20surface%20methodology" title=" organic acid response surface methodology"> organic acid response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=biorefinery" title=" biorefinery"> biorefinery</a> </p> <a href="https://publications.waset.org/abstracts/21515/optimization-of-diluted-organic-acid-pretreatment-on-rice-straw-using-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21515.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">654</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">3326</span> Physico-Chemical, GC-MS Analysis and Cold Saponification of Onion (Allium cepa L) Seed Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A%20Warra">A.

There were significant differences in terms of lactic, acetic, succinic, propionic, formic and butyric acid production (p < 0.005) among bacterial strains. Acetic acid production was the lowest by LAB while succinic acid followed by propionic acid was synthesized at the highest levels. Lactic acid production ranged from 0 to 938 mg/L by all LAB strains in different infusion broth. The highest acetic acid production was found by Lb. acidophilus and Lb. delbrueckii subsp. lactic in octopus and shrimp infusion broth, with values of 872 and 674 mg/L, respectively while formic acid formation ranged from 1747 mg/L by Lb. acidophilus in octopus infusion broth to 69 mg/L by Lb. delbrueckii subsp. lactis in shrimp infusion broth. Propionic acid and butyric acid productions by St. thermophilus were 9852 and 3999 mg/L in shrimp infusion broth while Leu. mes. subsp. cremoris synthesized 312 and 9 mg/L of those organic acid in European squid infusion broth, respectively. Apparently, LAB strains had a great capability to generate succinic acid followed by propionic and butyric acid. In addition, other organic acid production differed significantly depending on bacterial strains and growth medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lactic%20acid%20bacteria" title="Lactic acid bacteria ">Lactic acid bacteria </a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20acid" title=" organic acid"> organic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC%20analysis" title=" HPLC analysis"> HPLC analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20medium" title=" growth medium"> growth medium</a> </p> <a href="https://publications.waset.org/abstracts/72696/the-ability-of-organic-acids-production-by-lactic-acid-bacteria-in-m17-broth-and-squid-shrimp-octopus-eel-infusion-broth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72696.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">385</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">3320</span> Microwave Assisted Extraction (MAE) of Castor Oil from Castor Bean</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Faisal%20Najmuldeen">Ghazi Faisal Najmuldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosli%20Mohd%20Yunus"> Rosli Mohd Yunus</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurfarahin%20Bt%20Harun"> Nurfarahin Bt Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mardhiana%20Binti%20Ismail"> Mardhiana Binti Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The microwave extraction has attracted great interest among the researchers. The main virtue of the microwave technique is cost-effective, time saving and simple handling procedure. Castor beans was chosen because of its high content in fatty acid, especially ricinoleic acid. The purpose of this research is to extract the castor oil by using the microwave assisted extraction (MAE) using ethanol as solvent and to investigate the influence of extraction time on castor oil yield and to characterize the main composition of the produced castor oil by using the GC-MS. It was found that there is a direct dependence between the oil yield and the time of extraction as it increases from 45% to 58% as the time increase from 10 min to 60 min. The major components of castor oil detected by GC-MS were ricinoleic acid, linoleic acid and oleic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwave%20assisted%20extraction%20%28MAE%29" title="microwave assisted extraction (MAE)">microwave assisted extraction (MAE)</a>, <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title=" castor oil"> castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=ricinoleic%20acid" title=" ricinoleic acid"> ricinoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=linoleic%20acid" title=" linoleic acid"> linoleic acid</a> </p> <a href="https://publications.waset.org/abstracts/10844/microwave-assisted-extraction-mae-of-castor-oil-from-castor-bean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10844.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">505</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3319</span> Protective Effect of Protocatechuic Acid Alone and in Combination with Ascorbic Acid in Aniline Hydrochloride Induced Spleen Toxicity in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aman%20Upaganlawar">Aman Upaganlawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Upasana%20Khairnar"> Upasana Khairnar</a>, <a href="https://publications.waset.org/abstracts/search?q=Chandrashekhar%20Upasani"> Chandrashekhar Upasani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was designed to evaluate the protective effects of protocatechuic acid alone and in combination with ascorbic acid in aniline hydrochloride-induced spleen toxicity in rats. Male Wistar rats of either sex (200-250g) were used and divided into different groups. Spleen toxicity was induced by aniline hydrochloride (100 ppm) in drinking water for 28 days. Treatment group received protocatechuic acid (40 mg/kg/day, p.o), ascorbic acid (40 mg/kg/day, p.o), and combination of protocatechuic acid (20 mg/kg/day, p.o) and ascorbic acid (20 mg/kg/day, p.o) followed by aniline hydrochloride. At the end of treatment period, serum and tissue parameters were evaluated. Rats supplemented with aniline hydrochloride showed a significant alteration in body weight, spleen weight, feed consumption, water intake, hematological parameters (Hemoglobin content, Red Blood Cells, White Blood Cells and Total iron content), tissue parameters (Lipid peroxidation, Reduced glutathione, Nitric oxide content) compared to control group. Histopathology of aniline hydrochloride-induced spleen showed significant damage compared to control rats. Treatment with Protocatechuic acid along with ascorbic acid showed better protection as compared to protocatechuic acid or ascorbic acid alone in aniline hydrochloride-induced spleen toxicity. In conclusion Treatment with protocatechuic acid and ascorbic acid in combination showed significant protection in aniline hydrochloride-induced splenic toxicity in rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aniline" title="aniline">aniline</a>, <a href="https://publications.waset.org/abstracts/search?q=spleen%20toxicity" title=" spleen toxicity"> spleen toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=protocatechuic%20acid" title=" protocatechuic acid"> protocatechuic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title=" ascorbic acid"> ascorbic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title=" antioxidants"> antioxidants</a> </p> <a href="https://publications.waset.org/abstracts/52559/protective-effect-of-protocatechuic-acid-alone-and-in-combination-with-ascorbic-acid-in-aniline-hydrochloride-induced-spleen-toxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52559.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">358</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">3318</span> The Effect of Acid Treatment of PEDOT: PSS Anode for Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Borazan">Ismail Borazan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayse%20Celik%20Bedeloglu"> Ayse Celik Bedeloglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Demir"> Ali Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Carroll"> David Carroll</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this project, PEDOT:PSS layer was treated with formic acid, sulphuric acid, and hydrochloric acid, methanol, acetone, and dichlorobenzene:methanol.

Wong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we will demonstrate the feasibility of selectively removing the azo dye, Acid Red 1, in the presence of a second dye, Indigo Carmine, at conducting polypyrrole films. A long-term goal of this work is to develop an efficient and effective electrochemical treatment of textile effluents that does not yield any toxic by-products. Specifically, pyrrole was initially electrochemically oxidised in the presence of Acid Red 1 to prepare an Acid Red 1-entrapped polypyrrole film. Next, the Acid Red 1 entrapped film was electrochemically reduced to expel the dye from the film. The film was then ready for use in removing the dye in an Acid Red 1 solution. The entrapment efficiency of the film was then studied by spectroscopically determining the change in the absorbance of the dye solution. These experiments were repeated using Indigo Carmine or a mixture of Acid Red 1 and Indigo Carmine, in place of Acid Red 1. Therefore, this has given rise to an environmentally friendly treatment method for textile effluents. In our work, we have also studied the characteristics of Acid Red 1- and Indigo Carmine-entrapped polypyrrole films by scanning electron microscopy, X-ray diffraction and Fourier transfer infrared spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=azo%20dye" title="azo dye">azo dye</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20treatment" title=" electrochemical treatment"> electrochemical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=polypyrrole" title=" polypyrrole"> polypyrrole</a>, <a href="https://publications.waset.org/abstracts/search?q=Acid%20Red%201" title=" Acid Red 1"> Acid Red 1</a> </p> <a href="https://publications.waset.org/abstracts/13793/characteristics-of-a-dye-entrapped-polypyrrole-film-prepared-in-the-presence-of-a-different-dye" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13793.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">407</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">3316</span> Quality Rabbit Skin Gelatin with Acetic Acid Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wehandaka%20Pancapalaga">Wehandaka Pancapalaga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to analyze the water content, yield, fat content, protein content, viscosity, gel strength, pH, melting and organoleptic rabbit skin gelatin with acetic acid extraction levels are different.

ChCl-AA and ChCl-CA experienced a drop in viscosity from 9.678 to 1.429 and 22.658 卤 1.655 mm2/s, respectively as the water content in the DES increased from 0 to 50 wt% which contributed to higher extraction efficiency for the ferulic acid.

The importance of hyaluronic acid increased in the last decades. It has many applications in medicine and cosmetics. Hyaluronic acid has been used in attempts to treat osteoarthritis of the knee via injecting it into the joint. Bovine serum albumin (also known as BSA) is a protein derived from cows, which has many biochemical applications. The aim of our research work was to compare the thermal degradation of hyaluronic acid and BSA in powder and in solution, by determining changes in molar mass and conformation, by using SEC-MALLS (size exclusion chromatography -multi angle laser light scattering). The aim of our research work was to observe the degradation in powder and in solution of different molar mass hyaluronic acid samples, at different temperatures for certain periods. The degradation of the analyzed samples was mainly observed by modifications in molar mass. <p class="card-text"><strong>Keywords:</strong> <a
