To recognize the underground distribution of Cu in the mine tailing dam, nine profiles were excavated and surveyed in the central area of the deserted copper tailing dam. Soil samples from different layers of each profile were collected separately. The copper content in the tailing dam exceeded the toxic threshold of plants much, indicating high potential risk to local environment. The Copper of total and available contents both had the high heterogeneity in the horizontal direction. In the vertical direction, the total and available form of Cu displayed an opposite trend. The copper in the surface soil was easier to resolve, transport and transform than that in the subsoil.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85098671","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 gels were respectively imaged by Typhoon 9400 using different emission filter and spot-features were analyzed by DeCyder5.0 software in each paired normal/disease comparison. 11 different expression proteins were selected, in which 7 proteins were successfully identified. In their proteins, the expression of Glucose regulated protein (grp75), heat shock protein 60, carbamoyl-phosphate synthetase 1, ATP synthetase, sarcosine dehydrogenase, chaperone protein, dimethylglycine dehydrogenase increased while the expression of adenylate kinas4 decreased. These result showed that the metabolism of substance was affected by hydrocortisone. The expression of heat shock protein and Glucose regulated protein increased, which contributed to protect the cell from damage. The metabolism of protein increased and the energy metabolism was alleviated to increase the output of ATP. However, the stability of energy metabolism and the ability of self-regulation were disturbed when the rats were injected with hydrocortisone.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81612061","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 results show that there is some impact on the degradation rate of ammonia degradation for the presence of fibrillation earthworm, but little for the removal effect of final ammonia and COD, especially the final ammonia.

GacS/ GacA homologs have since been identified in some plant pathogenic bacterial. A current model proposes that GacS senses a still-unknown signal and activates, via a phosphorelay mechanism, the GacA transcription regulator, which in turn triggers the expression of target genes. Certain genes whose expression is regulated by the GacS/GacA system are regulated in parallel by the small RNA binding protein RsmA (CsrA) at a posttranscriptional level. It is suggested that the GacS/GacA system operates a switch between primary and secondary metabolism, with a major involvement of posttranscriptional control mechanisms.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84881171","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}

During DBS operation, general anesthetic induction has been shown an alternative procedure to avoid patient's discomfort under local anesthesia. Meanwhile, microelectrode recording (MER) is a guide of optimal placement in the brain. However, the inhibition of power of neural spiking is assumed by the general anesthesia during the process. Therefore, we use median nerve stimulation (MNS) to enhance them. At the same time, the power of background noise is also enhanced. Then, it makes MER be poor to determine the optimal electrode placement. In this study, we present a methodology including spike detection, fast Fourier transformation and power spectrum analysis for analyzing MER. Through these results, MER data can be successfully utilized for tracking dorsolateral sub thalamic nucleus (STN) to ensure optimal electrode location.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83795490","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}
