variations of a base program and checking whether a candidate test suite can identify all the mutants that are not semantically equivalent to the base: this technique is widely used by researchers to select quality test suites. One of the main obstacles to the widespread use of mutation testing is cost: even small pro-grams (a few dozen lines of code) can give rise to a large number of mutants (up to hundreds): this has created an incentive to seek to reduce the number of mutants while preserving their collective effectiveness. Two criteria have been used to reduce the size of mutant sets: equiva-lence, which aims to partition the set of mutants into equivalence classes modulo semantic equivalence, and selecting one representative per class; subsumption, which aims to define a partial ordering among mutants that ranks mutants by effectiveness and seeks to select maximal elements in this ordering. In this paper we analyze these two policies using analytical and em-pirical criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mutation%20testing" title="mutation testing">mutation testing</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant%20sets" title=" mutant sets"> mutant sets</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant%20equivalence" title=" mutant equivalence"> mutant equivalence</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant%20subsumption" title=" mutant subsumption"> mutant subsumption</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant%20set%20minimization" title=" mutant set minimization"> mutant set minimization</a> </p> <a href="https://publications.waset.org/abstracts/156274/minimizing-mutant-sets-by-equivalence-and-subsumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156274.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">63</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">1351</span> Total Lipid of Mutant Synechococcus sp.

The objective of this work was to study growth factors affecting marine mutant Synechococcus sp. (PCC 7002) for high lipid production. Four growth factors were investigated; nitrogen-phosporus-potassium (NPK) concentration, light intensity, temperature and NaNO3 concentration on mutant strain growth and lipid production were studied. Design Expert v8.0 was used to design the experimental and analyze the data. The experimental design selected was Min-Run Res IV which consists of 12 runs and the response surfaces measured were specific growth rate and lipid concentration. The extraction of lipid was conducted by chloroform/methanol solvents system. Based on the study, mutant Synechococcus sp. PCC 7002 gave the highest specific growth rate of 0.0014 h-1 at 0% NPK, 2500 lux, 40oC and 0% NaNO3. On the other hand, the highest lipid concentration was obtained at 0% NPK, 3500 lux, 30°C and 1% NaNO3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyanobacteria" title="Cyanobacteria">Cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid" title=" lipid"> lipid</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant" title=" mutant"> mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20Synechococcus%20sp.%20%28PCC%207002%29" title=" marine Synechococcus sp.

Expression of PprA or K133E mutant displayed a significant increase in cell length upto 5 folds while W183R mutant showed cell length similar to uninduced control cells. We checked the interaction of deinococcal PprA and its mutants with E. coli DnaA using Bacterial two-hybrid system and co-immunoprecipitation. We observed a functional interaction of EcDnaA with PprA and K133E mutant but not with W183R mutant of PprA.

The identification of structural or functional defects in the mutant KatGs responsible for INH resistance remains as an area to be explored. In this connection, the differences in the binding affinity between wild-type (WT) and mutants of KatG were investigated, through the generation of three mutants of KatG, Ser315Thr [S315T], Ser315Asn [S315N], Ser315Arg [S315R] and a WT [S315]) with the help of software-MODELLER. The mutants were docked with INH using the software-GOLD. The affinity is lower for WT than mutant, suggesting the tight binding of INH with the mutant protein compared to WT type. These models provide the in silico evidence for the binding interaction of KatG with INH and implicate the basis for rationalization of INH resistance in naturally occurring KatG mutant strains of Mycobacterium tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title="Mycobacterium tuberculosis">Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=KatG" title=" KatG"> KatG</a>, <a href="https://publications.waset.org/abstracts/search?q=INH%20resistance" title=" INH resistance"> INH resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=mutants" title=" mutants"> mutants</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a> </p> <a href="https://publications.waset.org/abstracts/6727/in-silico-analysis-of-isoniazid-resistance-in-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6727.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">1347</span> Some New Hesitant Fuzzy Sets Operator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20S.%20Thakur">G.

However, the economic exploitation in an open system seems to have been limited because of lack of multiple stress-tolerant strains. The present study aims to isolate a stable stress tolerant mutant of Spirulina platensis with improved growth rate and enhanced potential to produce its commercially valuable bioactive compounds. N-methyl-n'-nitro-n-nitrosoguanidine (NTG) at 250 μg/mL (concentration permitted 1% survival) was employed for chemical mutagenesis to generate random mutants and screened against NaCl. In a preliminary experiment, wild type S. platensis was treated with NaCl concentrations from 0.5-1.5 M to calculate its LC₅₀. Mutagenized colonies were then screened for tolerance at 0.8 M NaCl (LC₅₀), and the surviving colonies were designated as NaCl tolerant mutants of S. platensis. The mutant cells exhibited 1.5 times improved growth against NaCl stress as compared to the wild type strain in control conditions. This might be due to the ability of the mutant cells to protect its metabolic machinery against inhibitory effects of salt stress. Salt stress is known to adversely affect the rate of photosynthesis in cyanobacteria by causing degradation of the pigments. Interestingly, the mutant cells were able to protect its photosynthetic machinery and exhibited 4.23 and 1.72 times enhanced accumulation of Chl a and phycobiliproteins, respectively, which resulted in enhanced rate of photosynthesis (2.43 times) and respiration (1.38 times) against salt stress. Phycocyanin production in mutant cells was observed to enhance by 1.63 fold. Nitrogen metabolism plays a vital role in conferring halotolerance to cyanobacterial cells by influx of nitrate and efflux of Na+ ions from the cell. The NaCl tolerant mutant cells took up 2.29 times more nitrate as compared to the wild type and efficiently reduce it. Nitrate reductase and nitrite reductase activity in the mutant cells also improved by 2.45 and 2.31 times, respectively against salt stress. From these preliminary results, it could be deduced that enhanced nitrogen uptake and its efficient reduction might be a reason for adaptive and halotolerant behavior of the S. platensis mutant cells. Also, the NaCl tolerant mutant of S. platensis with significant improved growth and phycocyanin accumulation compared to the wild type can be commercially promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20mutagenesis" title="chemical mutagenesis">chemical mutagenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=NaCl%20tolerant%20mutant" title=" NaCl tolerant mutant"> NaCl tolerant mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20metabolism" title=" nitrogen metabolism"> nitrogen metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthetic%20machinery" title=" photosynthetic machinery"> photosynthetic machinery</a>, <a href="https://publications.waset.org/abstracts/search?q=phycocyanin" title=" phycocyanin"> phycocyanin</a> </p> <a href="https://publications.waset.org/abstracts/78322/isolation-of-nitrosoguanidine-induced-nacl-tolerant-mutant-of-spirulina-platensis-with-improved-growth-and-phycocyanin-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78322.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">168</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">1345</span> Enhancement of Rice Straw Composting Using UV Induced Mutants of Penicillium Strain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20N.%20M.%20El%20Sebai">T.

The mutants were obtained by exposing Penicillium strain to UV-light treatments. Screening and selection after treatment with UV-light were carried out using cellulolytic and xylanolytic clear zones method to select the hypercellulolytic and hyperxylanolytic mutants. These mutants were evaluated for their cellulase and xylanase enzyme production as well as their abilities for biodegradation of rice straw. The mutant 12 UV/1 produced 306.21% and 209.91% cellulase and xylanase, respectively, as compared with the original wild type strain. This mutant showed high capacity of rice straw degradation. The effectiveness of tested mutant strain and that of wild strain was compared in relation to enhancing the composting process of rice straw and animal manures mixture. The results obtained showed that the compost product of inoculated mixture with mutant strain (12 UV/1) was the best compared to the wild strain and un-inoculated mixture. Analysis of the composted materials showed that the characteristics of the produced compost were close to those of the high quality standard compost. The results obtained in the present work suggest that the combination between rice straw and animal manure could be used for enhancing the composting process of rice straw and particularly when applied with fungal decomposer accelerating the composting process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rice%20straw" title="rice straw">rice straw</a>, <a href="https://publications.waset.org/abstracts/search?q=composting" title=" composting"> composting</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20mutants" title=" UV mutants"> UV mutants</a>, <a href="https://publications.waset.org/abstracts/search?q=Penicillium" title=" Penicillium"> Penicillium</a> </p> <a href="https://publications.waset.org/abstracts/7467/enhancement-of-rice-straw-composting-using-uv-induced-mutants-of-penicillium-strain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7467.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">283</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">1344</span> Association of Vascular Endothelial Growth Factor Gene +405 C&gt;G and -460 T&gt;C Polymorphism with Type 2 Diabetic Foot Ulcer Patient in Cipto Mangunkusumo National Hospital Jakarta </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dedy%20Pratama">Dedy Pratama</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhmadu%20Muradi"> Akhmadu Muradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilman%20Ibrahim"> Hilman Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Raden%20Suhartono"> Raden Suhartono</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Jayadi%20Utama"> Alexander Jayadi Utama</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrianef%20Darwis"> Patrianef Darwis</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Dwi%20Anita"> S.

In this study, we performed this study to examine VEGF gene polymorphism associated with DFU. Methods: Case-control study of polymorphism of VEGF gene +405 C>G and -460 T>C, of diabetes mellitus (DM) type 2 with Diabetic Foot Ulcer (DFU) in Cipto Mangunkusumo National Hospital (RSCM) Jakarta from June to December 2016. Results: There were 203 patients, 102 patients with DFU and 101 patients without DFU. Forty-nine point 8 percent of total samples is male and 50,2% female with mean age 56,06 years. Distribution of the wild-type genotype VEGF +405 C>G wild type CC was found in 6,9% of respondents, the number of mutant heterozygote CG was 69,5% and mutant homozygote GG was 19,7%. Cumulatively, there were 6,9% wild-type and 85,2% mutant and 3,9% of total blood samples could not be detected on PCR-RFLP. Distribution of VEGF allele +405 C>G C alleles were 43% and G alleles were 57%. Distribution of genotype from VEGF gene -460 T>C is wild type TT 42,9%, mutant heterozygote TC 37,9% and mutant homozygote CC 13,3%. Cumulatively, there were 42,9% wild-type and 51% mutant type. Distribution of VEGF -460 T>C were 62% T allele and 38% C allele. Conclusion: In this study we found the distribution of alleles from VEGF +405 C>G is C 43% and G 57% and from VEGF -460 T>C; T 62% and C 38%. We propose that G allele in VEGF +405 C>G can act as a protective allele and on the other hands T allele in VEGF -460 T>C could be acted as a risk factor for DFU in diabetic patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetic%20foot%20ulcer" title="diabetic foot ulcer">diabetic foot ulcer</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=VEGF" title=" VEGF"> VEGF</a> </p> <a href="https://publications.waset.org/abstracts/65541/association-of-vascular-endothelial-growth-factor-gene-405-cg-and-460-tc-polymorphism-with-type-2-diabetic-foot-ulcer-patient-in-cipto-mangunkusumo-national-hospital-jakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65541.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">296</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">1343</span> A Study of Closed Sets and Maps with Ideals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asha%20Gupta">Asha Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramandeep%20Kaur"> Ramandeep Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to study a class of closed sets, called generalized pre-closed sets with respect to an ideal (briefly Igp-closed sets), which is an extension of generalized pre-closed sets in general topology.

Since the introduction of this concept, the application of soft sets has been restricted to associative algebraic structures (groups, semi groups, associative rings, semi-rings etc.). Acceptably, though the study of soft sets, where the base set of parameters is a commutative structure, has attracted the attention of many researchers for more than one decade. But on the other hand there are many sets which are naturally endowed by two compatible binary operations forming a non-associative ring and we may dig out examples which investigate a non-associative structure in the context of soft sets. Thus it seems natural to apply the concept of soft sets to non-commutative and non-associative structures. In present paper, we make a new approach to apply Molodtsoves notion of soft sets to LA-ring (a class of non-associative ring). We extend the study of soft commutative rings from theoretical aspect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20sets" title="soft sets">soft sets</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-rings" title=" LA-rings"> LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20LA-rings" title=" soft LA-rings"> soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20ideals" title=" soft ideals"> soft ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20prime%20ideals" title=" soft prime ideals"> soft prime ideals</a>, <a href="https://publications.waset.org/abstracts/search?q=idealistic%0D%0Asoft%20LA-rings" title=" idealistic soft LA-rings"> idealistic soft LA-rings</a>, <a href="https://publications.waset.org/abstracts/search?q=LA-ring%20homomorphism" title=" LA-ring homomorphism "> LA-ring homomorphism </a> </p> <a href="https://publications.waset.org/abstracts/33475/application-of-soft-sets-to-non-associative-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1341</span> Unravelling of the TOR Signaling Pathway in Human Fungal Pathogen Cryptococcus neoformans </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yee-Seul%20So">Yee-Seul So</a>, <a href="https://publications.waset.org/abstracts/search?q=Guiseppe%20Ianiri"> Guiseppe Ianiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Idnurm"> Alex Idnurm</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Sun%20Bahn"> Yong-Sun Bahn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tor1 is a serine/threonine protein kinase that is widely conserved across eukaryotic species. Tor1 was first identified in Saccharomyces cerevisiae as a target of rapamycin (TOR). The TOR pathway has been implicated in regulating cellular responses to nutrients, proliferation, translation, transcription, autophagy, and ribosome biogenesis. Here we identified two homologues of S. cerevisiae Tor proteins, CNAG_06642 (Tor1) and CNAG_05220 (Tlk1, TOR-like kinase 1), in Cryptococcus neoformans causing a life-threatening fungal meningoencephalitis. Both Tor1 and Tlk1 have rapamycin-binding (RB) domains but Tlk1 has truncated RB form. To study the TOR-signaling pathway in the fungal pathogen, we attempt to construct the tor1Δ and tlk1Δ mutants and phenotypically analyze them. Although we failed to construct the tor1Δ mutant, we successfully construct the tlk1Δ mutant. The tlk1Δ mutant does not exhibit any discernable phenotypes, suggesting that Tlk1 is dispensable in C. neoformans. The essentiality of TOR1 is independently confirmed by constructing the TOR1 promoter replacement strain by using a copper transporter 4 (CTR4) promoter and the TOR1/tor1 heterozygous mutant in diploid C. neoformans strain background followed by sporulation analysis. To further analyze the function of Tor1, we construct TOR1 overexpression mutant using a constitutively active histone H3 in C. neoformans. We find that the Tor1 overexpression mutant is resistant to rapamycin but the tlk1Δ mutant does not exhibit any altered resistance to rapamycin, further confirming that Tor1, but not Tlk1, is critical for TOR signaling. Furthermore, we found that Tor1 is involved in response to diverse stresses, including genotoxic stress, oxidative stress, thermo-stress, antifungal drug treatment, and production of melanin. To identify any TOR-related transcription factors, we screened C. neoformans transcription factor library that we constructed in our previous study and identified several potential downstream factors of Tor1, including Atf1, Crg1 and Bzp3. In conclusion, the current study provides insight into the role of the TOR signaling pathway in human fungal pathogens as well as C. neoformans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20pathogen" title="fungal pathogen">fungal pathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=serine%2Fthreonine%20kinase" title=" serine/threonine kinase"> serine/threonine kinase</a>, <a href="https://publications.waset.org/abstracts/search?q=target%20of%20rapamycin" title=" target of rapamycin"> target of rapamycin</a>, <a href="https://publications.waset.org/abstracts/search?q=transcription%20factor" title=" transcription factor"> transcription factor</a> </p> <a href="https://publications.waset.org/abstracts/69093/unravelling-of-the-tor-signaling-pathway-in-human-fungal-pathogen-cryptococcus-neoformans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69093.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">221</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">1340</span> Association of Transforming Growth Factor-β1 Gene 1800469 C &gt; T and 1982073 C &gt; T Polymorphism with Type 2 Diabetic Foot Ulcer Patient in Cipto Mangunkusumo National Hospital Jakarta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dedy%20Pratama">Dedy Pratama</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhmadu%20Muradi"> Akhmadu Muradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilman%20Ibrahim"> Hilman Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrianef%20Darwis"> Patrianef Darwis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Jayadi%20Utama"> Alexander Jayadi Utama</a>, <a href="https://publications.waset.org/abstracts/search?q=Raden%20Suhartono"> Raden Suhartono</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20Suryandari"> D.

The production and productivity of the crop are very limited in South Africa due to a lack of adapted and stable genotypes. The improvement of nutritional quality is made possible by manipulating the genes of diverse cowpea genotypes available around the world. Assessing the adaptability and stability of the cowpea mutant genotypes for yield and nutritional quality requires examining them in different environments. The objective of the study was to determine the adaptability and stability of cowpea mutant genotypes under South African conditions and to identify the superior genotypes that combine grain yield components, antioxidants, and nutritional quality. Thirty-one cowpea genotypes were obtained from the Agricultural Research Council grain crops (ARC-GC) and were planted in Glen, Mafikeng, Polokwane, Potchefstroom, Taung, and Vaalharts during the 2021/22 summer cropping season. Significant genotype by location interactions indicated the possibility of genetic improvement of these traits. The genotype plus genotype by environment indicated broad adaptability and stability of mutant genotypes. The principal component analysis identified the association of the genotypes with the traits. Phenotypic correlation analysis showed that Zn and protein content were significant and positively correlated and suggested the possibility of indirect selection of these traits. Results from this study could be used to help plant breeders in making informed decisions and developing nutritionally improved cowpea genotypes with the aim of addressing the challenges of poor nutritional quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cowpea%20seeds" title="cowpea seeds">cowpea seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptability" title=" adaptability"> adaptability</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20elements" title=" mineral elements"> mineral elements</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20content" title=" protein content"> protein content</a> </p> <a href="https://publications.waset.org/abstracts/152227/identification-of-superior-cowpea-mutant-genotypes-their-adaptability-and-stability-under-south-african-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152227.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">112</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">1338</span> The Contribution of Genetic Polymorphisms of Tumor Necrosis Factor Alpha and Vascular Endothelial Growth Factor into the Unfavorable Clinical Course of Ulcerative Colitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20I.%20Tretyakova">Y.

We examined 70 UC patients and 50 healthy donors during the active phase of the disease. Our focus was on TNF-α and VEGF concentration in the blood serum, as well as TNF-α and VEGFA gene polymorphisms at the -308G/А and -634G/C regions, respectively. We found that TNF-α and VEGF levels were significantly higher in patients with severe UC and high endoscopic activity compared to those with milder forms of the disease and low endoscopic activity. These tests could serve as additional non-invasive markers for assessing mucosal damage in the large intestine of UC patients. The frequency of allele variations in the TNF-α gene -308G/A (rs1800629) revealed a significantly higher occurrence of the unfavorable homozygote AA in UC patients compared to donors. Additionally, the major allele G and the allele pair GG were more frequent in patients with mild to moderate disease and 1-2 degree of endoscopic activity than in those with severe UC and 3-4 degree of endoscopic activity (χ2=14.19; p=0.000). We also observed a mutant allele A and the unfavorable homozygote AA associated with severe progressive UC. The occurrence of the mutant allele increased the risk of severe UC by 5 times (OR 5.03; CI 12.07-12.21). We did not find any significant differences in the frequency of the CC homozygote (χ2=1.02; p=0.6; OR=1.32) and the mutant allele C of the VEGFA gene -634G/C (rs 2010963) (χ2=0.01; p=0.913; OR=0.97) between groups of UC patients and healthy individuals. However, we detected that the mutant allele C and the unfavorable homozygote CC of the VEGFA gene were associated with more severe endoscopic changes in the colonic mucosa of UC patients (χ2=25,76; р=0,000; OR=0,15). The presence of the mutant allele increased the risk of severe UC by 6 times (OR 6,78; CI 3,13–14,7). We found a direct correlation between TNF-α and VEGFA gene polymorphisms, increased production of the same factors, disease severity, and endoscopic activity (р=0.000). Therefore, the presence of the mutant allele A and homozygote AA of the TNF-α gene at the -308G/A region and the mutant allele C and homozygote CC of the VEGFA gene at the -634G/C region are associated with risks related to an unfavorable clinical course of UC, frequent recurrences, and rapid progression. These findings should be considered when making prognoses regarding the clinical course of the disease and selecting treatment strategies. The presence of the homozygote AA in the TNF-α gene (rs1800629) is considered a sign of genetic predisposition to UC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gene%20polymorphism" title="gene polymorphism">gene polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=TNF-%CE%B1" title=" TNF-α"> TNF-α</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcerative%20colitis" title=" ulcerative colitis"> ulcerative colitis</a>, <a href="https://publications.waset.org/abstracts/search?q=VEGF" title=" VEGF"> VEGF</a> </p> <a href="https://publications.waset.org/abstracts/174671/the-contribution-of-genetic-polymorphisms-of-tumor-necrosis-factor-alpha-and-vascular-endothelial-growth-factor-into-the-unfavorable-clinical-course-of-ulcerative-colitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174671.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">74</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">1337</span> CMPD: Cancer Mutant Proteome Database</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Po-Jung%20Huang">Po-Jung Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Ching%20Lee"> Chi-Ching Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bertrand%20Chin-Ming%20Tan"> Bertrand Chin-Ming Tan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Ming%20Yeh"> Yuan-Ming Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Lichieh%20Chu"> Julie Lichieh Chu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tin-Wen%20Chen"> Tin-Wen Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Yang%20Lee"> Cheng-Yang Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruei-Chi%20Gan"> Ruei-Chi Gan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsuan%20Liu"> Hsuan Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Petrus%20Tang"> Petrus Tang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Whole-exome sequencing focuses on the protein coding regions of disease/cancer associated genes based on a priori knowledge is the most cost-effective method to study the association between genetic alterations and disease. Recent advances in high throughput sequencing technologies and proteomic techniques has provided an opportunity to integrate genomics and proteomics, allowing readily detectable mutated peptides corresponding to mutated genes. Since sequence database search is the most widely used method for protein identification using Mass spectrometry (MS)-based proteomics technology, a mutant proteome database is required to better approximate the real protein pool to improve disease-associated mutated protein identification. Large-scale whole exome/genome sequencing studies were launched by National Cancer Institute (NCI), Broad Institute, and The Cancer Genome Atlas (TCGA), which provide not only a comprehensive report on the analysis of coding variants in diverse samples cell lines but a invaluable resource for extensive research community. No existing database is available for the collection of mutant protein sequences related to the identified variants in these studies. CMPD is designed to address this issue, serving as a bridge between genomic data and proteomic studies and focusing on protein sequence-altering variations originated from both germline and cancer-associated somatic variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TCGA" title="TCGA">TCGA</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=mutant" title=" mutant"> mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=proteome" title=" proteome"> proteome</a> </p> <a href="https://publications.waset.org/abstracts/16077/cmpd-cancer-mutant-proteome-database" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16077.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">593</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">1336</span> An Attenuated Quadruple Gene Mutant of Mycobacterium tuberculosis Imparts Protection against Tuberculosis in Guinea Pigs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shubhita%20Mathur">Shubhita Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ritika%20Kar%20Bahal"> Ritika Kar Bahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Chauhan"> Priyanka Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20K.%20Tyagi"> Anil K. Tyagi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycobacterium tuberculosis, the causative agent of human tuberculosis, is a major cause of mortality. Bacillus Calmette-Guérin (BCG), the only licensed vaccine available for protection against tuberculosis confers highly variable protection ranging from 0%-80%. Thus, novel vaccine strains need to be evaluated for their potential as a vaccine against tuberculosis. We had previously constructed a triple gene mutant of M. tuberculosis (MtbΔmms), having deletions in genes encoding for phosphatases mptpA, mptpB, and sapM that are involved in host-pathogen interaction. Though vaccination with Mtb∆mms strain induced protection in the lungs of guinea pigs, the mutant strain was not able to control the hematogenous spread of the challenge strain to the spleens. Additionally, inoculation with Mtb∆mms resulted in some pathological damage to the spleens in the early phase of infection. In order to overcome the pathology caused by MtbΔmms in the spleens of guinea pigs and also to control the dissemination of the challenge strain, MtbΔmms was genetically modified by disrupting bioA gene to generate MtbΔmmsb strain. Further, in vivo attenuation of MtbΔmmsb was evaluated, and its protective efficacy was assessed against virulent M. tuberculosis challenge in guinea pigs. Our study demonstrates that Mtb∆mmsb mutant was highly attenuated for growth and virulence in guinea pigs. Vaccination with Mtb∆mmsb mutant generated significant protection in comparison to sham-immunized animals at 4 and 12 weeks post-infection in lungs and spleens of the infected animals. Our findings provide evidence that deletion of genes involved in signal transduction and biotin biosynthesis severely attenuates the pathogen and the single immunization with the auxotroph was able to provide significant protection as compared to sham-immunized animals. The protection imparted by Mtb∆mmsb fell short in comparison to the protection observed in BCG-immunized animals. This study nevertheless indicates the importance of attenuated multiple gene deletion mutants of M. tuberculosis in generating protection against tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title="Mycobacterium tuberculosis">Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=BCG" title=" BCG"> BCG</a>, <a href="https://publications.waset.org/abstracts/search?q=Mtb%CE%94mmsb" title=" MtbΔmmsb"> MtbΔmmsb</a>, <a href="https://publications.waset.org/abstracts/search?q=bioA" title=" bioA"> bioA</a>, <a href="https://publications.waset.org/abstracts/search?q=guinea%20pigs" title=" guinea pigs"> guinea pigs</a> </p> <a href="https://publications.waset.org/abstracts/109444/an-attenuated-quadruple-gene-mutant-of-mycobacterium-tuberculosis-imparts-protection-against-tuberculosis-in-guinea-pigs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109444.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">140</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">1335</span> Comparative Proteomic Analysis of Rice bri1 Mutant Leaves at Jointing-Booting Stage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiang%20Xu">Jiang Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Daoping%20Wang"> Daoping Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yinghong%20Pan"> Yinghong Pan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The jointing-booting stage is a critical period of both vegetative growth and reproductive growth in rice. Therefore, the proteomic analysis of the mutant Osbri1, whose corresponding gene OsBRI1 encodes the putative BRs receptor OsBRI1, at jointing-booting stage is very important for understanding the effects of BRs on vegetative and reproductive growth. In this study, the proteomes of leaves from an allelic mutant of the DWARF 61 (D61, OsBRI1) gene, Fn189 (dwarf54, d54) and its wild-type variety T65 (Taichung 65) at jointing-booting stage were analysed by using a Q Exactive plus orbitrap mass spectrometer, and more than 3,100 proteins were identified in each sample. Ontology analysis showed that these proteins distribute in various space of the cells, such as the chloroplast, mitochondrion, and nucleus, they functioned as structural components and/or catalytic enzymes and involved in many physiological processes. Moreover, quantitative analysis displayed that 266 proteins were differentially expressed in two samples, among them, 77 proteins decreased and 189 increased more than two times in Fn189 compared with T65, the proteins whose content decreased in Fn189 including b5-like Heme/Steroid binding domain containing protein, putative retrotransposon protein, putative glutaminyl-tRNA synthetase, and higher content proteins such as mTERF, putative Oligopeptidase homologue, zinc knuckle protein, and so on. A former study founded that the transcription level of a mTERF was up-regulated in the leaves of maize seedling after EBR treatment. In our experiments, it was interesting that one mTERF protein increased, but another mTERF decreased in leaves of Fn189 at jointing-booting stage, which suggested that BRs may have differential regulation mechanisms on the expression of various mTERF proteins. The relationship between other differential proteins with BRs is still unclear, and the effects of BRs on rice protein contents and its regulation mechanisms still need further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bri1%20mutant" title="bri1 mutant">bri1 mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=jointing-booting%20stage" title=" jointing-booting stage"> jointing-booting stage</a>, <a href="https://publications.waset.org/abstracts/search?q=proteomic%20analysis" title=" proteomic analysis"> proteomic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a> </p> <a href="https://publications.waset.org/abstracts/85257/comparative-proteomic-analysis-of-rice-bri1-mutant-leaves-at-jointing-booting-stage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85257.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1334</span> A Fuzzy Nonlinear Regression Model for Interval Type-2 Fuzzy Sets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Poleshchuk">O.

Our goal is to improve this potential by enhancing growth rate and other properties of <em>D. salina</em> under optimal growth conditions. We used ethyl methane sulfonate (EMS) to generate random mutants in <em>D. salina </em>KU11, a strain classified in Thailand. In a preliminary experiment, we first treated <em>D. salina</em> cells with 0%, 0.8%, 1.0%, 1.2%, 1.44% and 1.66% EMS to generate a killing curve. After that, we randomly picked 30 candidates from approximately 300 isolated survivor colonies from the 1.44% EMS treatment (which permitted 30% survival) as an initial test of the mutant screen. Among the 30 survivor lines, we found that 2 strains (mutant #17 and #24) had significantly improved growth rates and cell number accumulation at stationary phase approximately up to 1.8 and 1.45 fold, respectively, 2 strains (mutant #6 and #23) had significantly decreased growth rates and cell number accumulation at stationary phase approximately down to 1.4 and 1.35 fold, respectively, while 26 of 30 lines had similar growth rates compared with the wild type control. We also analyzed cell size for each strain and found there was no significant difference comparing all mutants with the wild type. In addition, mutant #24 had shown an increase of biomass accumulation approximately 1.65 fold compared with the wild type strain on day 5 that was entering early stationary phase. From these preliminary results, it could be feasible to identify <em>D. salina</em> mutants with significant improved growth rate, cell accumulation and biomass production compared to the wild type for the further study; this makes it possible to improve this microorganism as a platform for biotechnology application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dunaliella%20salina" title="Dunaliella salina">Dunaliella salina</a>, <a href="https://publications.waset.org/abstracts/search?q=ethyl%20methyl%20sulfonate" title=" ethyl methyl sulfonate"> ethyl methyl sulfonate</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20rate" title=" growth rate"> growth rate</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a> </p> <a href="https://publications.waset.org/abstracts/52505/ethyl-methane-sulfonate-induced-dunaliella-salina-ku11-mutants-affected-for-growth-rate-cell-accumulation-and-biomass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52505.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">241</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">1332</span> Synthesis of Novel Uracil Non-nucleosides Analogues of the Reverse Transcriptase Inhibitors Emivirine and TNK-651 </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasser%20R.%20El-Brollosy">Nasser R.

The capsular polysaccharides that contribute to pathogenesis through evasion of the host innate immune system are also involved in hindering leukocyte killing of enterococci. The gene cluster (enterococcal polysaccharide antigen) of E. faecalis encoding homologues of many genes involved in polysaccharide biosynthesis. We identified two putative loci with 22 kb and 19 kb which contained 11 genes encoding for glycosyltransferases (GTFs); this was confirmed by using genome comparison of already sequenced strains that has no homology to known capsule genes and the epa-locus. The polysaccharide-conjugate vaccines have rapidly emerged as a suitable strategy to combat different pathogenic bacteria, therefore, we investigated a polysaccharide biosynthesis CapD protein in E. faecium contains 336 amino acids and had putative function for N-linked glycosylation. The deletion/knock-out capD mutant was constructed and complemented by homologues recombination method and confirmed by using PCR and sequencing. For further characterization and functional analysis, in-vitro cell culture and in-vivo a mouse infection models were used. Our ΔcapD mutant shows a strong hydrophobicity and all strains exhibited biofilm production. Subsequently, the opsonic activity was tested in an opsonophagocytic assay which shows increased in mutant compared complemented and wild type strains but more than two fold decreased in colonization and adherence was seen on surface of uroepithelial cells. However, a significant higher bacterial colonialization was observed in capD mutant during animal bacteremia infection. Unlike other polysaccharides biosynthesis proteins, CapD does not seems to be a major virulence factor in enterococci but further experiments and attention is needed to clarify its function, exact mechanism and involvement in pathogenesis of enteroccocal nosocomial infections eventually to develop a vaccine/ or targeted therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20faecium" title="E. faecium">E. faecium</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogenesis" title=" pathogenesis"> pathogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=polysaccharides" title=" polysaccharides"> polysaccharides</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title=" biofilm formation"> biofilm formation</a> </p> <a href="https://publications.waset.org/abstracts/31270/identification-and-characterization-of-polysaccharide-biosynthesis-protein-capd-of-enterococcus-faecium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31270.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">333</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">1328</span> Assessing the Blood-Brain Barrier (BBB) Permeability in PEA-15 Mutant Cat Brain using Magnetization Transfer (MT) Effect at 7T</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sultan%20Z.%20Mahmud">Sultan Z.

Recently it has been discovered that PEA-15 is crucial in normal neurodevelopment of domestic cats, a gyrencephalic animal model, although the exact function of PEA-15 in neurodevelopment is unknown. This study investigates how PEA-15 affects the blood-brain barrier (BBB) permeability in cat brain, which can cause abnormalities in tissue metabolite and energy supplies. Severe polymicrogyria and microcephaly have been observed in cats with a loss of function PEA-15 mutation, affecting the normal neurodevelopment of the cat. This suggests that the vital role of PEA-15 in neurodevelopment is associated with gyrification. Neurodevelopment is a highly energy demanding process. The mammalian brain depends on glucose as its main energy source. PEA-15 plays a very important role in glucose uptake and utilization by interacting with phospholipase D1 (PLD1). Mitochondria also plays a critical role in bioenergetics and essential to supply adequate energy needed for neurodevelopment. Cerebral blood flow regulates adequate metabolite supply and recent findings also showed that blood plasma contains mitochondria as well. So the BBB can play a very important role in regulating metabolite and energy supply in the brain. In this study the blood-brain permeability in cat brain was measured using MRI magnetization transfer (MT) effect on the perfusion signal. Perfusion is the tissue mass normalized supply of blood to the capillary bed. Perfusion also accommodates the supply of oxygen and other metabolites to the tissue. A fraction of the arterial blood can diffuse to the tissue, which depends on the BBB permeability. This fraction is known as water extraction fraction (EF). MT is a process of saturating the macromolecules, which has an effect on the blood that has been diffused into the tissue while having minimal effect on intravascular blood water that has not been exchanged with the tissue. Measurement of perfusion signal with and without MT enables to estimate the microvascular blood flow, EF and permeability surface area product (PS) in the brain. All the experiments were performed with Siemens 7T Magnetom with 32 channel head coil. Three control cats and three PEA-15 mutant cats were used for the study. Average EF in white and gray matter was 0.9±0.1 and 0.86±0.15 respectively, perfusion in white and gray matter was 85±15 mL/100g/min and 97±20 mL/100g/min respectively, PS in white and gray matter was 201±25 mL/100g/min and 225±35 mL/100g/min respectively for control cats. For PEA-15 mutant cats, average EF in white and gray matter was 0.81±0.15 and 0.77±0.2 respectively, perfusion in white and gray matter was 140±25 mL/100g/min and 165±18 mL/100g/min respectively, PS in white and gray matter was 240±30 mL/100g/min and 259±21 mL/100g/min respectively. This results show that BBB is compromised in PEA-15 mutant cat brain, where EF is decreased and perfusion as well as PS are increased in the mutant cats compared to the control cats. This findings might further explain the function of PEA-15 in neurodevelopment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BBB" title="BBB">BBB</a>, <a href="https://publications.waset.org/abstracts/search?q=cat%20brain" title=" cat brain"> cat brain</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetization%20transfer" title=" magnetization transfer"> magnetization transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=PEA-15" title=" PEA-15"> PEA-15</a> </p> <a href="https://publications.waset.org/abstracts/128208/assessing-the-blood-brain-barrier-bbb-permeability-in-pea-15-mutant-cat-brain-using-magnetization-transfer-mt-effect-at-7t" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128208.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">143</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">1327</span> The Effect of Program Type on Mutation Testing: Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Falah">B.

Recently, many cost and mutants&rsquo; reduction techniques have been developed, improved, and experimented, but few of them has relied the possibility of reducing the cost of mutation testing on the program type of the application under test. This paper is a comparative study between four operators&rsquo; selection techniques (mutants sampling, class level operators, method level operators, and all operators&rsquo; selection) based on the program code type of each application under test. It aims at finding an alternative approach to reveal the effect of code type on mutation testing score. The result of our experiment shows that the program code type can affect the mutation score and that the programs using polymorphism are best suited to be tested with mutation testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equivalent%20mutant" title="equivalent mutant">equivalent mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=killed%20mutant" title=" killed mutant"> killed mutant</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation%20score" title=" mutation score"> mutation score</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation%20testing" title=" mutation testing"> mutation testing</a>, <a href="https://publications.waset.org/abstracts/search?q=program%20code%20type" title=" program code type"> program code type</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title=" software testing"> software testing</a> </p> <a href="https://publications.waset.org/abstracts/34959/the-effect-of-program-type-on-mutation-testing-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34959.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">555</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">1326</span> Hyper-Production of Lysine through Fermentation and Its Biological Evaluation on Broiler Chicks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shagufta%20Gulraiz">Shagufta Gulraiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abu%20Saeed%20Hashmi"> Abu Saeed Hashmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Mohsin%20Javed"> Muhammad Mohsin Javed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lysine required for poultry feed is imported in Pakistan to fulfil the desired dietary needs. Present study was designed to produce maximum lysine by utilizing cheap sources to save the foreign exchange. To achieve the goal of lysine production through fermentation, large scale production of lysine was carried out in 7.5 L stirred glass vessel fermenter with wild and mutant Brevibacterium flavum (B. flavum) using all pre-optimized conditions. The identification of produced lysine was carried out by TLC and amino acid analyzer. Toxicity evaluation of produced lysine was performed before feeding to broiler chicks. During biological trial concentrated fermented broth having 8% lysine was used in poultry rations as a source of Lysine for test birds. Fermenter scale studies showed that the maximum lysine (20.8 g/L) was produced at 250 rpm, 1.5 vvm aeration, 6.0% inoculum under controlled pH conditions after 56 h of fermentation with wild culture but mutant (BFENU2) gave maximum yield of lysine 36.3 g/L under optimized condition after 48 h. Amino acid profiling showed 1.826% Lysine in fermented broth by wild B. flavum and 2.644% by mutant strain (BFENU2). Toxicity evaluation report showed that the produced lysine is safe for consumption by broilers. Biological evaluation results showed that produced lysine was equally good as commercial lysine in terms of weight gain, feed intake and feed conversion ratio. A cheap and practical bioprocess of Lysine production was concluded, that can be exploited commercially in Pakistan to save foreign exchange. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lysine" title="lysine">lysine</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=broiler%20chicks" title=" broiler chicks"> broiler chicks</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20evaluation" title=" biological evaluation"> biological evaluation</a> </p> <a href="https://publications.waset.org/abstracts/23326/hyper-production-of-lysine-through-fermentation-and-its-biological-evaluation-on-broiler-chicks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23326.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">548</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">1325</span> Efficient Recommendation System for Frequent and High Utility Itemsets over Incremental Datasets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20K.%20Kavitha">J.

When the data arrives sporadically, incremental and interactive rule mining and utility mining approaches can be adopted to handle user’s dynamic environmental needs and avoid redundancies, using previous data structures, and mining results. The dependence on recommendation systems has exponentially risen since the advent of search engines. This paper proposes a model for building a recommendation system that suggests frequent and high utility item sets over dynamic datasets for a cluster based location prediction strategy to predict user’s trajectories using the Efficient Incremental Rule Mining (EIRM) algorithm and the Fast Update Utility Pattern Tree (FUUP) algorithm. Through comprehensive evaluations by experiments, this scheme has shown to deliver excellent performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20sets" title="data sets">data sets</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20system" title=" recommendation system"> recommendation system</a>, <a href="https://publications.waset.org/abstracts/search?q=utility%20item%20sets" title=" utility item sets"> utility item sets</a>, <a href="https://publications.waset.org/abstracts/search?q=frequent%20item%20sets%20mining" title=" frequent item sets mining"> frequent item sets mining</a> </p> <a href="https://publications.waset.org/abstracts/47560/efficient-recommendation-system-for-frequent-and-high-utility-itemsets-over-incremental-datasets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47560.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">293</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1324</span> Effect of SCN5A Gene Mutation in Endocardial Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helan%20Satish">Helan Satish</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ramasubba%20Reddy"> M.

The characterization of Brugada Syndrome by loss of function effect on SCN5A mutation due to L812Q mutant present in the DII-S4 transmembrane region of the NaV1.5 channel protein and its effect in an endocardial cell is studied. Ten Tusscher model of human ventricular action potential is modified to incorporate the changes contributed by L812Q mutant in the endocardial cells. Results show that BrS-associated SCN5A mutation causes reduction in the inward sodium current by modifications in the channel gating dynamics such as delayed activation, enhanced inactivation, and slowed recovery from inactivation in the endocardial cell. A decrease in the inward sodium current was also observed, which affects depolarization phase (Phase 0) that leads to reduction in the spike amplitude of the cardiac action potential. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SCN5A%20gene%20mutation" title="SCN5A gene mutation">SCN5A gene mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20channel" title=" sodium channel"> sodium channel</a>, <a href="https://publications.waset.org/abstracts/search?q=Brugada%20syndrome" title=" Brugada syndrome"> Brugada syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20arrhythmia" title=" cardiac arrhythmia"> cardiac arrhythmia</a>, <a href="https://publications.waset.org/abstracts/search?q=action%20potential" title=" action potential"> action potential</a> </p> <a href="https://publications.waset.org/abstracts/126001/effect-of-scn5a-gene-mutation-in-endocardial-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126001.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">126</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">1323</span> Building 1-Well-Covered Graphs by Corona, Join, and Rooted Product of Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vadim%20E.%20Levit">Vadim E. Levit</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugen%20Mandrescu"> Eugen Mandrescu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A graph is well-covered if all its maximal independent sets are of the same size. A well-covered graph is 1-well-covered if deletion of every vertex of the graph leaves it well-covered. It is known that a graph without isolated vertices is 1-well-covered if and only if every two disjoint independent sets are included in two disjoint maximum independent sets. Well-covered graphs are related to combinatorial commutative algebra (e.g., every Cohen-Macaulay graph is well-covered, while each Gorenstein graph without isolated vertices is 1-well-covered). Our intent is to construct several infinite families of 1-well-covered graphs using the following known graph operations: corona, join, and rooted product of graphs. Adopting some known techniques used to advantage for well-covered graphs, one can prove that: if the graph G has no isolated vertices, then the corona of G and H is 1-well-covered if and only if H is a complete graph of order two at least; the join of the graphs G and H is 1-well-covered if and only if G and H have the same independence number and both are 1-well-covered; if H satisfies the property that every three pairwise disjoint independent sets are included in three pairwise disjoint maximum independent sets, then the rooted product of G and H is 1-well-covered, for every graph G. These findings show not only how to generate some more families of 1-well-covered graphs, but also that, to this aim, sometimes, one may use graphs that are not necessarily 1-well-covered. <p
