The effect of initial glucose and ethanol concentrations were investigated for specific productivity. The inhibitory ethanol concentration was observed at 100 g/L. In order to increase the fermentation performance, the ethanol product was removed as soon as it is produced. The broth was boiled at 35°C by reducing the pressure to 65 mBar. The ethanol/water vapor was fractionated for up to 90 wt% before leaving the column. Ethanol concentration in the broth was kept lower than 25 g/L, thus minimized the product inhibition effect to the yeast cells. For batch extractive fermentation, a high substrate utilization rate was obtained at 26.6 g/L.h and most of glucose was consumed within 21 h. For repeated-batch extractive fermentation, addition of glucose was carried out up to 9 times and ethanol was produced more than 8-fold higher than batch fermentation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethanol" title="ethanol">ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=extractive%20fermentation" title=" extractive fermentation"> extractive fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=product%20inhibition" title=" product inhibition"> product inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20fractionation" title=" vacuum fractionation"> vacuum fractionation</a> </p> <a href="https://publications.waset.org/abstracts/12965/extractive-fermentation-of-ethanol-using-vacuum-fractionation-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12965.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">250</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">4701</span> Pathological Gambling and Impulsivity: Comparison of the Eight Laboratory Measures of Inhibition Capacities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semion%20Kertzman">Semion Kertzman</a>, <a href="https://publications.waset.org/abstracts/search?q=Pinhas%20Dannon"> Pinhas Dannon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Impulsive behaviour and the underlying brain processes are hypothesized to be central in the development and maintenance of pathological gambling. Inhibition ability can be differentially impaired in pathological gamblers (PGs). Aims: This study aimed to compare the ability of eight widely used inhibition measures to discriminate between PGs and healthy controls (HCs). Methods: PGs (N=51) and demographically matched HCs (N=51) performed cognitive inhibition (the Stroop), motor inhibition (the Go/NoGo) and reflective inhibition (the Matching Familiar Figures (MFFT)) tasks. Results: An augmented total interference response time in the Stroop task (η² =0.054), a large number of commission errors (η² =0.053) in the Go/NoGo task, and the total number of errors in the MFFT (η² =0.05) can discriminate PGs from HCs. Other measures are unable to differentiate between PGs and HCs. No significant correlations were observed between inhibition measures. Conclusion: Inhibition measures varied in the ability to discriminate PGs from HCs. Most inhibition measures were not relevant to gambling behaviour. PGs do not express rash, impulsive behaviour, such as quickly choosing an answer without thinking. In contrast, in PGs, inhibition impairment was related to slow-inaccurate performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pathological%20gambling" title="pathological gambling">pathological gambling</a>, <a href="https://publications.waset.org/abstracts/search?q=impulsivity" title=" impulsivity"> impulsivity</a>, <a href="https://publications.waset.org/abstracts/search?q=neurocognition" title=" neurocognition"> neurocognition</a>, <a href="https://publications.waset.org/abstracts/search?q=addiction" title=" addiction"> addiction</a> </p> <a href="https://publications.waset.org/abstracts/54541/pathological-gambling-and-impulsivity-comparison-of-the-eight-laboratory-measures-of-inhibition-capacities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54541.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">302</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">4700</span> Study of the Antimicrobial Activity of Aminoreductone against Pathogenic Bacteria in Comparison with Other Antibiotics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vu%20Thu%20Trang">Vu Thu Trang</a>, <a href="https://publications.waset.org/abstracts/search?q=Lam%20Xuan%20Thanh"> Lam Xuan Thanh</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Sarter"> Samira Sarter</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomoko%20Shimamura"> Tomoko Shimamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroaki%20Takeuchi%E3%80%80%E3%80%80"> Hiroaki Takeuchi　　</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antimicrobial activities of aminoreductone (AR), a product formed in the initial stage of Maillard reaction, were screened against pathogenic bacteria.

The inhibition zone for each isolate by AR (2.5 mg) ranged from 15±0 mm to 28.3±0.4 mm in diameter. The minimum inhibitory concentration (MIC) of AR ranging from 20 mM to 26 mM was proven in the seven isolates tested. AR also showed the similar effect of growth inhibition in comparison with antibiotics frequently used for the treatment of infections bacteria, such as amikacin, ciprofloxacin, meropennem, and levofloxacin.

Oloyede</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymorphonuclear neutrophils (PMNs) play a crucial role in a variety of infections caused by bacteria, fungi, and parasites. Indeed, the involvement of PMNs in host defence against Plasmodium falciparum is well documented both in vitro and in vivo. Many of the antimalarial drugs such as chloroquine used in the treatment of human malaria significantly reduce the immune response of the host in vitro and in vivo. Myeloperoxidase is the most abundant enzyme found in the polymorphonuclear neutrophil which plays a crucial role in its function. This study was carried out to investigate the effect of chloroquine on the enzyme. In investigating the effects of the drug on myeloperoxidase, the influence of concentration, pH, partition ratio estimation and kinetics of inhibition were studied. This study showed that chloroquine is concentration-dependent inhibitor of myeloperoxidase with an IC50 of 0.03 mM. Partition ratio estimation showed that 40 enzymatic turnover cycles are required for complete inhibition of myeloperoxidase in the presence of chloroquine. The influence of pH on the effect of chloroquine on the enzyme showed significant inhibition of myeloperoxidase at physiological pH. The kinetic inhibition studies showed that chloroquine caused a non-competitive inhibition with an inhibition constant Ki of 0.27mM. The results obtained from this study shows that chloroquine is a potent inhibitor of myeloperoxidase and it is capable of inactivating the enzyme. It is therefore considered that the inhibition of myeloperoxidase in the presence of chloroquine as revealed in this study may partly explain the impairment of polymorphonuclear neutrophil and consequent immunosuppression of the host defence system against secondary infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myeloperoxidase" title="myeloperoxidase">myeloperoxidase</a>, <a href="https://publications.waset.org/abstracts/search?q=chloroquine" title=" chloroquine"> chloroquine</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition" title=" inhibition"> inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=neutrophil" title=" neutrophil"> neutrophil</a>, <a href="https://publications.waset.org/abstracts/search?q=immune" title=" immune"> immune</a> </p> <a href="https://publications.waset.org/abstracts/7033/immunosupressive-effect-of-chloroquine-through-the-inhibition-of-myeloperoxidase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7033.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">374</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">4697</span> The Equality Test of Ceftriaxone Anti-Bacterial Effect and Ethanol Extract of Ant Plant (Myermecodia pendens Merr. and L.

Therefore, the prevention and effort to control MRSA is still very important to conduct. One of the preventions of MRSA, which have been reported by several studies, is Cefriaxone and Ethanol Extract of Ant Plant. This research is an experimental test to determine the potency of MRSA’s anti-bacterial with Cefriaxone (30 μg) and Ethanol Extract of Ant Plant (13 mg/ml) based on inhibition zone on LAB (Lempeng Agar Biasa). The size of inhibition zone that is formed on Cefriaxone is adjusted with CSLI criteria, which ≥ 21 mm of inhibition zone is called sensitive; ≤13 mm is called resistance and between 14-20 mm is called intermediate. This research is conducted three times. Comparative test between Cefriaxone and Ethanol Extract of Ant Plant is analyzed by Maan Whitney’s statistic method. The Result of Cefriaxone anti-bacterial potency shows the variety of inhibition zone. Cefriaxone forms approximately 16,5-20 mm with average 18,22mm of inhibition zone that make Cefriaxone’s criteria to MRSA’s inhibition is intermediate. Anti-bacterial potency of Ethanol Extract of Ant Plant is about 0,5-2 mm with average 1,17 mm of inhibition zone that prove MRSA is sensitive to Ant Plant. The conclusion of this research shows that Cefriaxone is intermediate to MRSA’s inhibition, while MRSA is sensitive to Ethanol Extract of Ant Plant, which at the end; it creates different potency of anti-bacterial between Cefriaxone and Ethanol Extract of Ant Plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MRSA" title="MRSA">MRSA</a>, <a href="https://publications.waset.org/abstracts/search?q=cefriaxone" title=" cefriaxone"> cefriaxone</a>, <a href="https://publications.waset.org/abstracts/search?q=ant%20plant" title=" ant plant"> ant plant</a>, <a href="https://publications.waset.org/abstracts/search?q=CSLI" title=" CSLI"> CSLI</a>, <a href="https://publications.waset.org/abstracts/search?q=mann%20whitney" title=" mann whitney"> mann whitney</a> </p> <a href="https://publications.waset.org/abstracts/39334/the-equality-test-of-ceftriaxone-anti-bacterial-effect-and-ethanol-extract-of-ant-plant-myermecodia-pendens-merr-and-l-m-perry-to-mrsa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39334.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">4696</span> Mechanism of Changing a Product Concept</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kiyohiro%20Yamazaki">Kiyohiro Yamazaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to examine the hypothesis explaining the mechanism in the case, where the product is deleted or reduced the fundamental function of the product through the product concept changes in the digital camera industry.

Results indicate that inhibition ability of AMRE increases with the increasing amount of the extract. A maximum corrosion inhibition of 94% is acknowledged at the extract concentration of 400 mg L-1. Polarization curves and impedance spectra reveal that both cathodic and anodic reactions are suppressed due to passive layer formation at metal-acid interface. It is also confirmed by SEM micro graphs and FTIR studies. Furthermore, the effects of acid concentration (1-5 M), immersion time (120 hours) and temperature (30-60˚C) on inhibition potential of AMRE have been investigated by weight loss method and electrochemical techniques.

However, the molecular mechanism how CPT acts on mTOR is unknown. Here, cancer cells expressing rapamycin-resistant mutant mTOR are also sensitive to CPT, while phosphorylation of AMPK and TSC2 was activated, suggesting that CPT inhibition of mTOR maybe due to activating upstream of mTOR, AMPK, but not directly binding to and inhibiting mTOR. Further results indicated that Compound C, inhibitor of AMPK, could partially reversed CPT inhibition effect on cancer cells, and dominant-negative AMPK in cancer cells conferred resistance to CPT inhibition of 4EBP1 and phosphorylation of S6K1, as well as sh-AMPK. Furthermore, compared with MEF cells with AMPK positive, MEF cells with AMPK knock out are less sensitive to CPT by the findings that 4E-BP1 and phosphorylation of S6K1 express comparatively much. Furthermore, downexpression of TSC2 slightly recovered expression of 4EBP1 and phosphorylation of S6K1, while co-immunoprecipitation of TSC2 did not affect expression of TSC1 by CPT. Collectively, the above-mentioned results suggest that CPT inhibited mTOR pathway mostly was due to activation of AMPK-TSC2 pathway rather than specific inhibition of mTOR and then induction of subsequent lethal cellular effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptotanshinone" title="cryptotanshinone">cryptotanshinone</a>, <a href="https://publications.waset.org/abstracts/search?q=AMPK" title=" AMPK"> AMPK</a>, <a href="https://publications.waset.org/abstracts/search?q=TSC2" title=" TSC2"> TSC2</a>, <a href="https://publications.waset.org/abstracts/search?q=mTOR" title=" mTOR"> mTOR</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20cells" title=" cancer cells"> cancer cells</a> </p> <a href="https://publications.waset.org/abstracts/2970/activation-of-ampk-tsc-axis-is-involved-in-cryptotanshinone-inhibition-of-mtor-signaling-in-cancer-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2970.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">489</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">4691</span> Chiral Amine Synthesis and Recovery by Using High Molecular Weight Amine Donors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Matassa">Claudia Matassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Hohne"> Matthias Hohne</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominic%20Ormerod"> Dominic Ormerod</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamini%20Satyawali"> Yamini Satyawali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Chiral amines integrate the backbone of several active pharmaceutical ingredients (APIs) used in modern medicine for the treatment of a vast range of diseases. Despite the demand, their synthesis remains challenging. Besides a range of chemicals and enzymatical methods, chiral amine synthesis using transaminases (EC 2.6.1.W) represents a useful alternative to access this important class of compounds. Even though transaminases exhibit excellent stereo and regioselectivity and the potential for high yield, the reaction suffers from a number of challenges, including the thermodynamic equilibrium, product inhibition, and low substrate solubility. In this work, we demonstrate a membrane assisted strategy for addressing these challenges. It involves the use of high molecular weight (HMW) amine donors for the transaminase-catalyzed synthesis of 4-phenyl-2-butylamine in both aqueous and organic solvent media. In contrast to common amine donors such as alanine or isopropylamine, these large molecules, provided in excess for thermodynamic equilibrium shifting, are easily retained by commercial nanofiltration membranes; thus a selective permeation of the desired smaller product amine is possible. The enzymatic transamination in aqueous media, combined with selective product removal shifted the equilibrium enhancing substrate conversion by an additional 25% compared to the control reaction. Along with very efficient amine product removal, there was undesirable loss of ketone substrate and low product concentration was achieved. The system was therefore further improved by performing the reaction in organic solvent (n-heptane). Coupling the reaction system with membrane-assisted product removal resulted in a highly concentrated and relatively pure ( > 97%) product solution. Moreover, a product yield of 60% was reached, compared to 15% without product removal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amine%20donor" title="amine donor">amine donor</a>, <a href="https://publications.waset.org/abstracts/search?q=chiral%20amines" title=" chiral amines"> chiral amines</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20situ%20product%20removal" title=" in situ product removal"> in situ product removal</a>, <a href="https://publications.waset.org/abstracts/search?q=transamination" title=" transamination"> transamination</a> </p> <a href="https://publications.waset.org/abstracts/110355/chiral-amine-synthesis-and-recovery-by-using-high-molecular-weight-amine-donors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110355.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">154</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">4690</span> Product Line Design with Customization in the Presence of Demand Uncertainty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Bagheri%20Tookanlou">Parisa Bagheri Tookanlou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyze a product line design problem faced by a manufacturing firm where the product line consists of a customized product in addition to a standard product and is offered in a market in which customers are heterogeneous on aesthetic attributes of the product. The customization level of a product is defined by the fraction of aesthetic attributes of the product that the manufacturer chooses to customize. In contrast to the existing literature on product line design that predominantly assumes deterministic demand, we consider the presence of demand uncertainty and frame the product line design problem in a single period (news vendor) setting. We examine the effect of demand uncertainty on product line decisions. Furthermore, we also examine how product line decisions are influenced by channel structure. While we use the centralized channel as a benchmark, we consider the decentralized dual channel where the customized product is sold through an online channel owned by the manufacturer and the standard product is sold through a retailer. We introduce a supply contract between the manufacturer and the retailer for improving channel efficiency and coordinate the distribution channel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=product%20line%20design" title="product line design">product line design</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20uncertainty" title=" demand uncertainty"> demand uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=customization%20level" title=" customization level"> customization level</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20channel" title=" distribution channel"> distribution channel</a> </p> <a href="https://publications.waset.org/abstracts/83258/product-line-design-with-customization-in-the-presence-of-demand-uncertainty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83258.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">186</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">4689</span> Measuring the Effectiveness of Response Inhibition regarding to Motor Complexity: Evidence from the Stroop Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Germ%C3%A1n%20G%C3%A1lvez-Garc%C3%ADa">Germán Gálvez-García</a>, <a href="https://publications.waset.org/abstracts/search?q=Marta%20Lavin"> Marta Lavin</a>, <a href="https://publications.waset.org/abstracts/search?q=Javiera%20Pe%C3%B1a"> Javiera Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Albayay"> Javier Albayay</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Bascour"> Claudio Bascour</a>, <a href="https://publications.waset.org/abstracts/search?q=Jesus%20Fernandez-Gomez"> Jesus Fernandez-Gomez</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicia%20P%C3%A9rez-G%C3%A1lvez"> Alicia Pérez-Gálvez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We studied the effectiveness of response inhibition in movements with different degrees of motor complexity when they were executed in isolation and alternately.

Both actions were performed separately and alternately in different experimental blocks. Repeated measures ANOVAs were used to compare reaction time, movement time, kinematic errors and Movement errors across conditions (experimental block, movement, and congruency). Delta plots were constructed to perform distributional analyses of response inhibition and accuracy rate. The effectiveness of response inhibition did not show difference when the movements were performed in separated blocks. Nevertheless, it showed differences when they were performed alternately in the same experimental block, being more effective for the lifting action. This could be due to a competition of the available resources during a more complex scenario which also demands to adopt some strategy to avoid errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=response%20inhibition" title="response inhibition">response inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20complexity" title=" motor complexity"> motor complexity</a>, <a href="https://publications.waset.org/abstracts/search?q=Stroop%20task" title=" Stroop task"> Stroop task</a>, <a href="https://publications.waset.org/abstracts/search?q=delta%20plots" title=" delta plots"> delta plots</a> </p> <a href="https://publications.waset.org/abstracts/78372/measuring-the-effectiveness-of-response-inhibition-regarding-to-motor-complexity-evidence-from-the-stroop-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78372.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">394</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">4688</span> Therapeutical Role of Copper Oxide Nanoparticles (CuO NPs) for Breast Cancer Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dipranjan%20Laha">Dipranjan Laha</a>, <a href="https://publications.waset.org/abstracts/search?q=Parimal%20Karmakar"> Parimal Karmakar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metal oxide nanoparticles are well known to generate oxidative stress and deregulate normal cellular activities. Among these, transition metals copper oxide nanoparticles (CuO NPs) are more compelling than others and able to modulate different cellular responses. In this work, we have synthesized and characterized CuO NPs by various biophysical methods. These CuO NPs (~30 nm) induce autophagy in human breast cancer cell line, MCF7 in a time and dose-dependent manner. Cellular autophagy was tested by MDC staining, induction of green fluorescent protein light chain 3 (GFP-LC3B) foci by confocal microscopy, transfection of pBABE-puro mCherry-EGFP-LC3B plasmid and western blotting of autophagy marker proteins LC3B, beclin1, and ATG5. Further, inhibition of autophagy by 3-Methyladenine (3-MA) decreased LD50 doses of CuO NPs. Such cell death was associated with the induction of apoptosis as revealed by FACS analysis, cleavage of PARP, dephosphorylation of Bad and increased cleavage product of caspase3. siRNA-mediated inhibition of autophagy-related gene beclin1 also demonstrated similar results. Finally, induction of apoptosis by 3-MA in CuO NPs treated cells were observed by TEM. This study indicates that CuO NPs are a potent inducer of autophagy which may be a cellular defense against the CuO NPs mediated toxicity and inhibition of autophagy switches the cellular response into apoptosis. A combination of CuO NPs with the autophagy inhibitor is essential to induce apoptosis in breast cancer cells.

Similarly, marine bromopyrrole alkaloids are well known for their diverse array of anti-infective properties. Hence, we have reported synthesis and in vitro HIV-1 RT inhibitory activity of a series of 4-thiazolidinone-bromopyrrole alkaloid hybrids tethered with amide linker. The results of in vitro HIV-1 RT kit assay showed that some of the compounds, such as 4c, 4d, and 4i could effectively inhibit RT activity. Among them, compounds 4c having 4-chlorophenyl substituted 4-thiazolidione ring was the best one with the IC50 value of 0.26 µM. The sturdy emerges with key structure-activity relationship that pyrrole-NH-free core benefited inhibition against HIV-1 RT inhibition.

Not all extracts were as potent as the original inhibitors such as clavulanic acid, the isolation and the structural elucidation of the active constituents in these extracts will provide useful means in the development of beta -lactamase inhibitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anchusa%20azurea" title="Anchusa azurea">Anchusa azurea</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20product" title=" natural product"> natural product</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=beta-lactamase" title=" beta-lactamase"> beta-lactamase</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitors" title=" inhibitors"> inhibitors</a> </p> <a href="https://publications.waset.org/abstracts/41796/v-lactamase-inhibitory-effects-of-anchusa-azurea-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41796.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">511</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">4684</span> Synthesis, Electrochemical and Theoretical Study of Corrosion Inhibition on Carbon Steel in 1M HCl Medium by 2,2'-(piperazine-1,4-diyl)bis(N-(4-bromophenyl)acetamide)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanghourte%20Mohamed">Tanghourte Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouassou%20Nazih"> Ouassou Nazih</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Mesky%20Mohammed"> El Mesky Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Znini%20Mohamed"> Znini Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mabrouk%20El%20Houssine"> Mabrouk El Houssine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, a distinct organic inhibitor, namely 2,2'-(piperazine-1,4-diyl)bis(N-(4-bromophenyl)acetamide) (PBRA), was synthesized and characterized using ¹H, ¹³C NMR, and IR spectroscopy. Subsequently, the inhibition effect of PBRA on the corrosion of carbon steel in 1 M HCl was studied using electrochemical measurements such as potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). The results showed that the inhibition efficiency increased with concentration, reaching 87% at 10-³M. Furthermore, PBRA remained effective at temperatures ranging from 298 to 328 K. The adsorption of the inhibitor onto carbon steel was well described by the Langmuir adsorption isotherm.

The enzyme has been reported to interact with some drugs to generate free radical which inhibits its activity. This study investigated the effects of artesunate on the activity of the enzyme and the subsequent effect on the host immune system. In investigating the effects of the drugs on myeloperoxidase, the influence of concentration, pH, partition ratio estimation and kinetics of inhibition were studied. This study showed that artesunate is concentration-dependent inhibitor of myeloperoxidase with an IC50 of 0.078mM. Partition ratio estimation showed that 60 enzymatic turnover cycles are required for complete inhibition of myeloperoxidase in the presence of artesunate. The influence of pH on the effect of artesunate on the enzyme showed least activity of myeloperoxidase at physiological pH. The kinetic inhibition studies showed that artesunate caused a competitive inhibition with an increase in the Km value from 0.12mM to 0.26mM and no effect on the Vmax value. The Ki value was estimated to be 2.5mM. The results obtained from this study show that artesunate is a potent inhibitor of myeloperoxidase and it is capable of inactivating the enzyme. It is considered that the inhibition of myeloperoxidase in the presence of artesunate as revealed in this study may partly explain the impairment of polymorphonuclear neutrophil and consequent reduction of the strength of the host defense system against secondary infections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myeloperoxidase" title="myeloperoxidase">myeloperoxidase</a>, <a href="https://publications.waset.org/abstracts/search?q=artesunate" title=" artesunate"> artesunate</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibition" title=" inhibition"> inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=nuetrophill" title=" nuetrophill "> nuetrophill </a> </p> <a href="https://publications.waset.org/abstracts/17692/the-effect-of-artesunate-on-myeloperoxidase-activity-of-human-polymorphonuclear-neutrophil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17692.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">365</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">4681</span> Product Development Process to Obtain Community Standard Product Certificate: A Case of Bangkhonthi, Samut Songkhram, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Supattra%20Pranee">Supattra Pranee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this research were to study the product development process to obtain a community standard product certificate and to set a guideline for the product development process to obtain the community product certificate.

New product often involves new features that consumers might not be familiar with while it may also have a competitive advantage to attract consumers compared to established products. However, although most online retailers employ recommendation agents (RA) to influence consumers’ product choice decision, recommended new products are not accepted and chosen as expected. We argue that it might also be caused by providing a new product recommendation in the wrong way at the wrong time. This study seeks to discuss how new product evaluations sourced from third parties could be employed in RAs as evidence of the superiority for the new product and how the new product recommendation could be provided to a consumer at the right time so that it can be accepted and finally chosen during the consumer’s decision-making process. A 2*2 controlled laboratory experiment was conducted to understand the selection of new product recommendation sources and recommendation timing. Human subjects were randomly assigned to one of the four treatments to minimize the effects of individual differences on the results. Participants were told to make purchase choices from our product categories. We find that a new product recommended right after a similar existing product and with the source of the expert review will be more likely to be accepted.

The experimental results have showed that this compound revealed a good corrosion inhibition and the inhibition efficiency is increased with the inhibitor concentration to reach 98%. The results obtained revealed that the adsorption of the inhibitor molecule onto metal surface is found to obey Langmuir adsorption isotherm. The temperature effect on the corrosion behavior of copper in 1 M HNO3 without and with inhibitor at different concentration was studied in the temperature range from 303 to 333 K and the kinetic parameters activation such as Ea, ∆Ha and ∆Sa were evaluated. Tafel plot analysis revealed that oleic acid acts as a mixed type inhibitor. SEM analysis substantiated the formation of protective layer over the copper surface. <p class="card-text"><strong>Keywords:</strong> <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=weight%20loss" title=" weight loss"> weight loss</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20measurement" title=" electrochemical measurement"> electrochemical measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM%20analysis" title=" SEM analysis"> SEM analysis</a> </p> <a href="https://publications.waset.org/abstracts/36283/corrosion-inhibition-of-copper-in-1m-hno3-solution-by-oleic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36283.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4674</span> Effect of Thermal Treatment on Phenolic Content, Antioxidant, and Alpha-Amylase Inhibition Activities of Moringa stenopetala Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Assefa">Daniel Assefa</a>, <a href="https://publications.waset.org/abstracts/search?q=Engeda%20Dessalegn"> Engeda Dessalegn</a>, <a href="https://publications.waset.org/abstracts/search?q=Chetan%20Chauhan"> Chetan Chauhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Moringa stenopetala is a socioeconomic valued tree that is widely available and cultivated in the Southern part of Ethiopia. The leaves have been traditionally used as a food source with high nutritional and medicinal values. The present work was carried out to evaluate the effect of thermal treatment on the total phenolic content, antioxidant and alpha-amylase inhibition activities of aqueous leaf extracts during maceration and different decoction time interval (5, 10 and 15 min). The total phenolic content was determined by the Folin-ciocalteu methods whereas antioxidant activities were determined by 2,2-diphenyl-1-picryl-hydrazyl(DPPH) radical scavenging, reducing power and ferrous ion chelating assays and alpha-amylase inhibition activity was determined using 3,5-dinitrosalicylic acid method. Total phenolic content ranged from 34.35 to 39.47 mgGAE/g. Decoction for 10 min extract showed ferrous ion chelating (92.52), DPPH radical scavenging (91.52%), alpha-amylase inhibition (69.06%) and ferric reducing power (0.765), respectively. DPPH, reducing power and alpha-amylase inhibition activities showed positive linear correlation (R2=0.853, R2= 0.857 and R2=0.930), respectively with total phenolic content but ferrous ion chelating activity was found to be weakly correlated (R2=0.481). Based on the present investigation, it could be concluded that major loss of total phenolic content, antioxidant and alpha-amylase inhibition activities of the crude leaf extracts of Moringa stenopetala leaves were observed at decoction time for 15 min. Therefore, to maintain the total phenolic content, antioxidant, and alpha-amylase inhibition activities of leaves, cooking practice should be at the optimum decoction time (5-10 min). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpha-amylase%20inhibition" title="alpha-amylase inhibition">alpha-amylase inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa%20stenopetala" title=" Moringa stenopetala"> Moringa stenopetala</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolic%20content" title=" total phenolic content"> total phenolic content</a> </p> <a href="https://publications.waset.org/abstracts/51567/effect-of-thermal-treatment-on-phenolic-content-antioxidant-and-alpha-amylase-inhibition-activities-of-moringa-stenopetala-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51567.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">361</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">4673</span> The Effects of Kinesio Tape® and No Tape for Muscle Facilitation and Inhibition, for Collegiate Athletes with Self-Reported Shoulder Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gregory%20Chown">Gregory Chown</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Infantolino"> Benjamin Infantolino</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Wise"> Christopher Wise</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Holmes"> Rachel Holmes</a>, <a href="https://publications.waset.org/abstracts/search?q=Samantha%20%20O%27Donnell"> Samantha O'Donnell</a>, <a href="https://publications.waset.org/abstracts/search?q=Katelyn%20Pfeiffer"> Katelyn Pfeiffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Ward"> Victoria Ward</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: There is a lack of understanding of how Kinesio Tape® physiologically works. Furthermore, few studies compare Kinesio Tape® to other forms of taping. The research question is: Does Kinesio Tape® cause a difference in muscle facilitation, inhibition, and pain, between Kinesio Tape® and no tape for collegiate athletes with self-reported shoulder pain? Method: This quantitative non-randomized design used a convenience sampling method. There were eleven participants with self-reported shoulder pain who were athletes on the men’s and women’s lacrosse and tennis teams. Participants attended one 30-45 minute session for data collection. Each participant received all three taping conditions and performed four repetitions of 120 degrees of active shoulder flexion for the three separate trials (no tape, Kinesio Tape® inhibition, and Kinesio Tape® facilitation). Surface electromyography (sEMG) electrodes were placed on the anterior deltoid, supraspinatus, and lower trapezius to measure muscle facilitation and inhibition. Each participant completed the visual analogue scale (VAS) before and after each trial to measure pain. Results: No statistical significance was found for pain scores on the VAS between the taping methods of facilitation, inhibition, and no tape (p = .118). No statistical significance was found for the percentage of change in muscle function for each taping method; Anterior deltoid (p = .993), supraspinatus (p = .997) and lower trapezius (p = .922). Conclusion: Based on the results, Kinesio Tape® appears to not have an effect on muscle function or pain when utilizing the facilitation or inhibition taping method when compared to no tape. <p
