Hydrazine derivatives are used in different spheres, in aero-space activity, medical practice, laboratory-diagnosis practice and etc. For Kazakhstan, which has the cosmodrome "Baikonur", the problem of environmental pollution by rocket fuel and its components is important issue. An unsymmetrical dimethylhydrazine is mostly used as rocket fuel for launch vehicles which has high toxicity to humans and animals referred to the World Health Organization. The question about influence of hydrazine derivatives on human organism and ways of detoxication is very actual and requires special approaches in solving these problems. In connection with this situation, we set the goal: study the negative influence of hydrazine derivatives-hydrazine sulphur, nitrosodimethylamine (NDMA), phenylhydrazine, isonicotinic acid hydrazide (IAH) on some biochemical parameters of blood, hepatobiliary system and correction of functional damages of organism with “Salsocollin” drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isonicotinic%20acid%20hydrazide%20%28IAH%29" title="isonicotinic acid hydrazide (IAH)">isonicotinic acid hydrazide (IAH)</a>, <a href="https://publications.waset.org/abstracts/search?q=N-nitrosodimethylamine%20%28NDMA%29" title=" N-nitrosodimethylamine (NDMA)"> N-nitrosodimethylamine (NDMA)</a>, <a href="https://publications.waset.org/abstracts/search?q=AlAT-alanine%20aminotransferase" title=" AlAT-alanine aminotransferase"> AlAT-alanine aminotransferase</a>, <a href="https://publications.waset.org/abstracts/search?q=AsAT-aspartate%20aminotransaminase" title=" AsAT-aspartate aminotransaminase "> AsAT-aspartate aminotransaminase </a> </p> <a href="https://publications.waset.org/abstracts/16379/some-changes-in-biochemical-parameters-of-body-and-hepato-biliary-system-under-the-influence-of-hydrazine-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16379.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">355</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">3346</span> Development of Broad Spectrum Nitrilase Biocatalysts and Bioprocesses for Nitrile Biotransformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Vellore%20Sunder">Avinash Vellore Sunder</a>, <a href="https://publications.waset.org/abstracts/search?q=Shikha%20Shah"> Shikha Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Pramod%20P.%20Wangikar"> Pramod P. Wangikar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The enzymatic conversion of nitriles to carboxylic acids by nitrilases has gained significance in the green synthesis of several pharmaceutical precursors and fine chemicals. While nitrilases have been characterized from different sources, the industrial application requires the identification of nitrilases that possess higher substrate tolerance, wider specificity and better thermostability, along with the development of an efficient bioprocess for producing large amounts of nitrilase. To produce large amounts of nitrilase, we developed a fed-batch fermentation process on defined media for the high cell density cultivation of E. coli cells expressing the well-studied nitrilase from Alcaligenes fecalis. A DO-stat feeding approach was employed combined with an optimized post-induction strategy to achieve nitrilase titer of 2.5*105 U/l and 78 g/l dry cell weight. We also identified 16 novel nitrilase sequences from genome mining and analysis of substrate binding residues. The nitrilases were expressed in E. coli and their biocatalytic potential was evaluated on a panel of 22 industrially relevant nitrile substrates using high-throughput screening and HPLC analysis. Nine nitrilases were identified to exhibit high activity on structurally diverse nitriles including aliphatic and aromatic dinitriles, heterocyclic, -hydroxy and -keto nitriles. With fed-batch biotransformation, whole-cell Zobelia galactanivorans nitrilase achieved yields of 2.4 M nicotinic acid and 1.8 M isonicotinic acid from 3-cyanopyridine and 4-cyanopyridine respectively within 5 h, while Cupravidus necator nitrilase enantioselectively converted 740 mM mandelonitrile to (R)–mandelic acid. The nitrilase from Achromobacter insolitus could hydrolyze 542 mM iminodiacetonitrile in 1 h. The availability of highly active nitrilases along with bioprocesses for enzyme production expands the toolbox for industrial biocatalysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocatalysis" title="biocatalysis">biocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=isonicotinic%20acid" title=" isonicotinic acid"> isonicotinic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=iminodiacetic%20acid" title=" iminodiacetic acid"> iminodiacetic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=mandelic%20acid" title=" mandelic acid"> mandelic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrilase" title=" nitrilase"> nitrilase</a> </p> <a href="https://publications.waset.org/abstracts/141515/development-of-broad-spectrum-nitrilase-biocatalysts-and-bioprocesses-for-nitrile-biotransformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141515.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">234</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">3345</span> Discerning of Antimicrobial Potential of Phenylpropanoic Acid Derived Oxadiazoles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20Kumar%20Fuloria">Neeraj Kumar Fuloria</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivkanya%20Fuloria"> Shivkanya Fuloria</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20%20Singh"> Amit Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 2-Phenyl propionic acid and oxadiazoles possess antimicrobial potential. 2-Phenyl propane hydrazide (1), on cyclization with aromatic acids offered 2-aryl-5-(1-phenylethyl)-1,3,4-oxadiazole derivatives (1A-E).

Acid solutions are widely used for removal of undesirable scale and rust in many industrial processes. Among the commercially available acids hydrochloric acid is widely used for pickling, cleaning, de-scaling and acidization of oil process. Mild steel exhibits poor corrosion resistance in presence of hydrochloric acid. The high reactivity of mild steel in presence of hydrochloric acid is due to the soluble nature of ferrous chloride formed and the cementite phase (Fe3C) normally present in the steel is also readily soluble in hydrochloric acid. Pitting attack is also reported to be a major form of corrosion in mild steel in the presence of high concentrations of acids and thereby causing the complete destruction of metal. Hydrogen from acid reacts with the metal surface and makes it brittle and causes cracks, which leads to pitting type of corrosion. The use of chemical inhibitor to minimize the rate of corrosion has been considered to be the first line of defense against corrosion. In spite of long history of corrosion inhibition, a highly efficient and durable inhibitor that can completely protect mild steel in aggressive environment is yet to be realized. It is clear from the literature review that there is ample scope for the development of new organic inhibitors, which can be conveniently synthesized from relatively cheap raw materials and provide good inhibition efficiency with least risk of environmental pollution. The aim of the present work is to evaluate the electrochemical parameters for the corrosion inhibition behavior of an aromatic hydrazide derivative, 4-hydroxy- N '-[(E)-1H-indole-2-ylmethylidene)] benzohydrazide (HIBH) on mild steel in 2M hydrochloric acid using Tafel polarization and electrochemical impedance spectroscopy (EIS) techniques at 30-60 °C. The results showed that inhibition efficiency increased with increase in inhibitor concentration and decreased marginally with increase in temperature. HIBH showed a maximum inhibition efficiency of 95 % at 8×10-4 M concentration at 30 °C. Polarization curves showed that HIBH act as a mixed-type inhibitor. The adsorption of HIBH on mild steel surface obeys the Langmuir adsorption isotherm. The adsorption process of HIBH at the mild steel/hydrochloric acid solution interface followed mixed adsorption with predominantly physisorption at lower temperature and chemisorption at higher temperature. Thermodynamic parameters for the adsorption process and kinetic parameters for the metal dissolution reaction were determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20parameters" title="electrochemical parameters">electrochemical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=EIS" title=" EIS"> EIS</a>, <a href="https://publications.waset.org/abstracts/search?q=mild%20steel" title=" mild steel"> mild steel</a>, <a href="https://publications.waset.org/abstracts/search?q=tafel%20polarization" title=" tafel polarization "> tafel polarization </a> </p> <a href="https://publications.waset.org/abstracts/27108/inhibition-of-mild-steel-corrosion-in-hydrochloric-acid-medium-using-an-aromatic-hydrazide-derivative" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27108.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">337</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">3343</span> Synthesis and Antimicrobial Profile of Newer Schiff Bases and Thiazolidinone Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20K.%20Fuloria">N.

The title compounds Ox-6a-f were prepared by simple reactions in which a flurbiprofen –COOH group was esterified with methanol in an acid-catalyzed medium, which was then reacted with hydrazine to afford the corresponding hydrazide. The acid hydrazide was then cyclized into 1,3,4-oxadiazole-2-thiol by reacting with CS2 in the presence of KOH. The title compounds Ox-6a-f were synthesized by the reaction of an –SH group with various alkyl/aryl chlorides, which involves an S-alkylation reaction. The structures of the synthesized Ox-6a-f derivatives were ascer- tained by spectroscopic data. The in silico molecular docking was performed against target proteins cyclooxygenase-2 COX-2 (PDBID 5KIR) and cyclooxygenase-1 COX-1 (PDBID 6Y3C) to determine the binding affinity of the synthesized compounds with these structures. It has been inferred that most of the synthesized compounds bind well with an active binding site of 5KIR compared to 6Y3C, and especially compound Ox-6f showed excellent binding affinity (7.70 kcal/mol) among all synthesized compounds Ox-6a-f. The molecular dynamic (MD) simulation has also been performed to check the stability of docking complexes of ligands with COX-2 by determining their root mean square deviation and root mean square fluctuation. Little fluctuation was observed in case of Ox-6f, which forms the most stable complex with COX-2. The comprehensive antioxidant potential of the synthesized compounds has been evaluated by determining their free radical scavenging activity, including DPPH, OH, nitric oxide (NO), and iron chelation assay. The derivative Ox-6f showed promising results with 80.23% radical scavenging potential at a dose of 100 μg/mL while ascorbic acid exhibited 87.72% inhibition at the same dose. The anti-inflammatory activity of the final products has also been performed, and inflammatory markers were assayed, such as a thiobarbituric acid-reducing substance, nitric oxide, interleukin-6 (IL-6), and COX-2. The derivatives Ox-6d and Ox-6f displayed higher anti-inflammatory activity, exhibiting 70.56% and 74.16% activity, respectively. The results were compared with standard ibuprofen, which showed 84.31% activity at the same dose, 200 μg/mL. The anti-inflammatory potential has been performed by following the carrageen-induced hind paw edema model, and results showed that derivative Ox-6f exhibited 79.83% reduction in edema volume compared to standard ibuprofen, which reduced 84.31% edema volume. As dry lab and wet lab results confirm each other, it has been deduced that derivative Ox-6f may serve as the lead structure to design potent compounds to address oxidative stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthetic%20chemistry" title="synthetic chemistry">synthetic chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20chemistry" title=" pharmaceutical chemistry"> pharmaceutical chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=oxadiazole%20derivatives" title=" oxadiazole derivatives"> oxadiazole derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory" title=" anti-inflammatory"> anti-inflammatory</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-cancer%20compounds" title=" anti-cancer compounds"> anti-cancer compounds</a> </p> <a href="https://publications.waset.org/abstracts/193708/synthesis-computational-studies-antioxidant-and-anti-inflammatory-bio-evaluation-of-25-disubstituted-134-oxadiazole-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193708.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">15</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">3341</span> Fatty Acid and Amino Acid Composition in Mene maculata in The Sea of Maluku</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semuel%20Unwakoly">Semuel Unwakoly</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinner%20Puppela"> Reinner Puppela</a>, <a href="https://publications.waset.org/abstracts/search?q=Maresthy%20Rumalean"> Maresthy Rumalean</a>, <a href="https://publications.waset.org/abstracts/search?q=Healthy%20Kainama"> Healthy Kainama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fish is a kind of food that contains many nutritions, one of those is the long chain of unsaturated fatty acids as omega-3 and omega-6 fatty acids and essential amino acid in enough amount for the necessity of our body.

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–MB, 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">3336</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.

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">3333</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.

This method is based on the reaction of 5-aminosalicylic acid with nitrite in acid medium to form diazonium ion, which is coupled with acetylacetone in basic medium to form azo dyes, which shows absorption maxima at 470 nm. The method obeys Beer’s law in the concentration range of 0.5-11.2 gml-1 of 5-aminosalicylic acid with acetylacetone. The molar absorptivity and Sandell’s sensitivity of 5-aminosalicylic acid -acetylacetone azo dye is 2.672 ×104 lmol-1cm-1, 5.731 × 10-3 gcm-2 respectively. The dye formed is stable for 10 hrs.

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">3327</span> Encryption and Decryption of Nucleic Acid Using Deoxyribonucleic Acid Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iftikhar%20A.%20Tayubi">Iftikhar A.

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">3325</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">3324</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.

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">3322</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.

Compound (3) was found to displayed good inhibition against AChE with an IC₅₀ value of 21.5 ± 0.022 μM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acetylcholinesterase" title="acetylcholinesterase">acetylcholinesterase</a>, <a href="https://publications.waset.org/abstracts/search?q=Callicarpa%20maingayi" title=" Callicarpa maingayi"> Callicarpa maingayi</a>, <a href="https://publications.waset.org/abstracts/search?q=euscaphic%20acid" title=" euscaphic acid"> euscaphic 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/132971/isolation-characterization-and-biological-activities-of-compounds-isolated-from-callicarpa-maingayi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132971.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">146</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> Application of Deep Eutectic Solvent in the Extraction of Ferulic Acid from Palm Pressed Fibre</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ng%20Mei%20Han">Ng Mei Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Nu%27man%20Abdul%20Hadi"> Nu'man Abdul Hadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extraction of ferulic acid from palm pressed fiber using deep eutectic solvent (DES) of choline chloride-acetic acid (ChCl-AA) and choline chloride-citric acid (ChCl-CA) are reported. Influence of water content in DES on the extraction efficiency was investigated. ChCl-AA and ChCl-CA experienced a drop in viscosity from 9.678 to 1.429 and 22.658 ± 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. Between 41,155 ± 940 mg/kg ferulic acid was obtained after 6 h reflux when ChCl-AA with 30 wt% water was used for the extraction compared to 30,940 ± 621 mg/kg when neat ChCl-AA was used. Although viscosity of the DES could be improved with the addition of water, there is a threshold where the DES could tolerate the presence of water without changing its solvent behavior. The optimum condition for extraction of ferulic acid from palm pressed fiber was heating for 6 h with DES containing 30 wt% water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20eutectic%20solvent" title="deep eutectic solvent">deep eutectic solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <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=palm%20fibre" title=" palm fibre"> palm fibre</a> </p> <a href="https://publications.waset.org/abstracts/165450/application-of-deep-eutectic-solvent-in-the-extraction-of-ferulic-acid-from-palm-pressed-fibre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3319</span> Synthesis, Characterization, and Application of Some Acid Dyes Derived from 1-Amino-4 Bromo-Anthraquine-2-Sulphonic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuradeen%20Abdullahi%20Nadabo">Nuradeen Abdullahi Nadabo</a>, <a href="https://publications.waset.org/abstracts/search?q=Kasali%20Adewale%20Bello"> Kasali Adewale Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Istifanus%20Chindo"> Istifanus Chindo</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Ayeni"> Nurudeen Ayeni </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ten acid dyes were synthesized from 1-amino-4-bromo anthraghinone-2 sulphuric acid by condensation with different substituted amilines.

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
