In the present study, we investigated the effects of LP-1 or LP-2 on cultured pancreatic d-cell tumor-derived cell line HIT-T15 that had undergone oxidative damage. The cell viability, insulin secretion, and intracellular reactive oxygen species (ROS) level were investigated in HIT-T15 cells after LP-, alloxan-, or both-treatment, respectively. The metabolic activity of d-cells was determined by MTT assay while the insulin secretion was detected by ELISA technique. Intracellular ROS was detected by fluorescent spectrophotometry using DCFH-DA. The treatment with LP-1 (>; 0.5 mg/ml) or LP-2 (>; 0.1 mg/ml) could significantly elevated the cell viability compared to untreated normal cells (p 1 mg/ml). Importantly, the viability of cells treated with 10 mg/ml LP-2 were almost restored to the levels of alloxan-untreated cells and completely prevented the lowering of glucose-stimulated insulin release. Our investigation suggested that LP-1 or LP-2 reduced the damage of alloxan-induced HIT-T15 cells through scavenging intracellular ROS level. And these data also provide some information when LP-1 or LP-2 is used as a bioactive component for developing a new anti-diabetic agent.","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":"81311377","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 concentrations of 7 pharmaceuticals from non-steroidal anti-inflammatory analgesics and antihyperlipidemics were examined in each treatment stages in STP3. And one anti-biotic was examined the removal efficiencies in three STPs. Salicylic acid was the most abundant analyte in the three STPs influent, up to ppb magnitude, followed by ibuprofen, diclofenac, naproxen, gemfibrozil, mefenamic acid and clofibric acid. The concentration of salicylic acid, ibuprofen, diclofenac, naproxen and gemfibrozil decreased at least by one order of magnitude after biological treatments. Mefenamic acid and clofibric acid were found not apparent removal efficiencies during these stages, which could indicate lower biodegradability. The different results of triclosan (TCS) removal were appeared in three sewage treatment plants, 79.46%, 64.11% and 31.95%, respectively. Now, the existing sewage treatment system only dependent on the activated sludge secondary treatment can not completely remove PPCPs.","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":"82476981","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}

Methods The inhibition rates of CAF with primary cell culture were observed by MTT method in 111 cases of breast carcinoma. The expressions of TS, ER in 111 cases of breast cancer and 38 cases of adenofibroma were examined by streptavidin-perosidase immunohistochemistry method. Results Positive rates of TS and ER were higher in breast carcinoma than that in adenofibroma. Expression of ER was related to histological type in breast carcinoma (P<;0.05). Expressions rates of TS and ER were related to lymph node metastasis (P<;0.05). The sensitive rate of CAF chemotherapy protocols was 44.1%. There was relationship between expressions of TS, ER and sensitive rate of CAF chemotherapy protocols. Conclusion: The overexpressions of TS, ER may play an important role in the carcinogenesis of breast cancer. Detection of TS, ER expressions in breast carcinoma may direct to choose CAF chemotherapy.","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":"82532119","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}

R & D Cloud CEIB has four general modules: Search engine (SE), manager of clinical trials (GEBID), anonymizer (ANON) and bioimage knowledge engine (BIKE). The BIKE is the central module and through its sub modules analyzes and generates knowledge to provide to the HSE through services. The technology used in R & D Cloud CEIB is completely based on Open Source. Within the BIKE, we focus on the development of the classifier module (BIKE-Classifier), which aims to establish a method for the extraction of biomarkers for bioimaging and subsequent analysis to obtain a classification in bioimaging available pools following GIMC diagnostic experiences.","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":"89191013","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}
