The codon usage bias of DEV UL53 gene and 26 reference herpesviruses were analyzed by EMBOSS program and RSCU. In addition, Phylogenetic tree indicated DEV was evolutionarily closer to CaHV-2, CaHV-3, MeHV-1. The ENC-GC3S plot revealed that the genetic heterogeneity in UL53 gene of herpesviruses was constrained by G+C content at the third codon position. Conclusions: The extent of codon usage bias in the DEV UL53 gene was highly correlated with the gene composition. Analysis of correspondence through the SAS statistics software showed the yeast expression system might be more suitable for the expression of DEV genes.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"50 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84723601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measurements of indoor environmental parameters, CO2, formaldehyde, NH3, Randon, and TVOC concentrations were performed, while the comprehensive air quality evaluation index was calculated to describe the employees's feeling of discomfort and indoor air classification. Results show that pollution levels of the exhibition hall classifed as Class II, and indoor air environment is in accordance with personal demand. It is revealed that the indoor air environment largely depents on the numbers of occupants and the indoor soureces owing to various human activities. This work can be used to help define the ideal or optimum exhibition environment.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"46 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73810574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result showed that pre-microRNA SNPs are negatively selected in respect to SNPs distribution between the pre-microRNA and their flanking regions. Interestingly, the seed regions show a higher SNP density than both the MIR and the other MIR regions excluding seed regions. Furthermore, the SNPs in the seed regions were found show fewer effects on the stability of the pre-microRNA secondary structure. The data suggest that there is a rapid evolution has occurred in the seed regions and these SNPs are tend to be more deleterious , being good candidates for causal phenotypic variability among chickens.

When concentration of aerobic granular sludge changed in the range of 2700 to 3600 mg/L, aerobic granular sludge had better settling performance, and chemical oxygen demand and NH4+-N removal efficiencies were higher than the conventional activated sludge.

The simulation results demonstrate that in low echo-signal-to-noise ratio (eSNR) conditions, the performance of chirp-coded pulse for elasticity imaging is much better than the conventional short pulse, and indicate that elastographic signal-to-noise ratio (SNRe) of strain images for chirp-coded pulse is a function of attenuation, electronic noise, applied strain, pulse length, compression filter and depth. Comparing the effects of two chirp-coded excitation/compression schemes on strain imaging, we demonstrate that under the conditions of low eSNR, the first scheme, the combination of chirp excitation pulse with window and matched compression filter, is suitable to be used in low attenuation situations, and the second scheme, the combination of chirp excitation pulse without window and mismatched compression filter, is fit to be used in high attenuation situations. Finally, we applied the second chirp-coded scheme to a real-time freehand ultrasound strain imaging system and phantom experimental results are consistent with that in simulation method.","PeriodicalId":6396,"journal":{"name":"2010 4th International Conference on Bioinformatics and Biomedical Engineering","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2010-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84595253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
