The procedure of EEG signal pattern recognition consisted of information acquisition, preprocessing, feature extraction and selection, classification estimation and recognition. By studying the association between EEG signal and prosthetic movement, it was concluded that EEG signal controlling prosthesis was feasible. Therefore, a prosthetic controlled system was designed based on EEG signal pattern recognition and acquisition. The system initiated from scalp electrode (or prosthetic electrode), passed through differential amplifier circuit (or prosthetic drive circuit), pre-amplifier circuit, notch circuit, med-amplifier circuit, and filter circuit, and finally reached analog-to-digital converter. The practice proves that this prosthetic controlled system can satisfy various requirements of EEG signal-controlled prosthesis pretty well.","PeriodicalId":415908,"journal":{"name":"2008 International Seminar on Future BioMedical Information Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116621262","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}

S180 tumor-bearing mice were set up to investigate the effects of juglone on tumor growth inhibition and apoptosis. After HE staining, the pathomorphologic changes of tumor cells were observed by optical microscope. The ultrastructural changes of tumor cells were observed by transmission electron microscopy. Flow cytometry was used to observe the apoptosis rate in S180 cells. The experimental results showed that the tumor inhibition rate at the dosage of 2, 4 and 8mumol/kg of juglone was 29.04%, 37.33%, 52.66% respectively. The tumor weight of all dose groups of juglone were lower significantly than that in blank control group (P<0.01). The typical morphological changes of apoptosis were observed, such as chromatin condensation, margination against nuclear envelope and formation of apoptotic bodies by transmission electron microscopy. The subdiploid peak was found and the apoptosis rate of juglone at the dosage of 2, 4 and 8 mumol/kg was 5.58plusmn0.63%, 6.66plusmn0.85%, 10.27plusmn1.05% respectively.

(CSBE), effect of apoptosis of SGC-7901 induced by CSBE was observed. In addition, the changes of initiator, effector and marker in process of mitochondria signal transduction pathway were surveyed. The inhibitory and killing effects of SGC-7901 induced by CSBE were studied by MTT method, and apoptosis of SGC-7901 induced by CSBE was observed with flowcytometry. Mitochondrial membrane potential was detected by SRB 123 to reveal initiator in mitochondrial apoptosis pathway induced by CSBE. The release of cytochrome C (Cyt c), marker of mitochondrial apoptosis pathway, was analyzed with western blot method. Activity of caspase 3 which was the effector of mitochondrial apoptosis pathway was measured by enzyme-labeled instrument. CBSE can inhibit growth of SGC-7901, and induce apoptosis. Proportion of apoptotic cell was increased as concentration of drug rised. CSBE could reduce mitochondrial membrane potential and initiate mitochondrial apoptosis pathway. After SGC-7901 was treated with CSBE, the up-regulation of expression of Cyt c in cytoplasm indicated that Cyt c was involved in apoptosis process induced by CSBE. CSBE could activate caspase-3, effector of mitochondrial apoptosis pathway, which caused apoptosis of SGC-7901. As a result, CSBE can induce mitochondrial PTP channel open of SGC-7901, and decrease mitochondrial membrane potential. In addition, CSBE could result in release of mitochondrial Cyt c, and cause activation of Caspase-3. Eventually SGC-7901 was induced apoptosis through mitochondrial signal transduction pathway.","PeriodicalId":415908,"journal":{"name":"2008 International Seminar on Future BioMedical Information Engineering","volume":"14 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693682","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}
