The aim of the study was to validate the ability of electrical impedance tomography (EIT) in detecting ventilation inhomogeneity caused by gravitation. Methods: Ten healthy volunteers were included for this prospective study. They were asked to breathe spontaneously in four different body positions, namely supine, prone, left lateral and right lateral positions. Functional EIT images were calculated and divided into four quadrants. Results: No significant difference of air distribution was found between gravity-dependent lung regions and nondependent lung regions in both supine and prone position, while significant difference was found in both lateral positions (left lateral, left and right lung respectively: 57.6±7.2%, 42.4±7.2%, p<0.01; right lateral, left and right lung respectively:, 35.3±6.7%, 64.7±6.7%, p<0.01). Conclusion: The results indicate that the influence of gravitation on ventilation distribution depends on body positions and EIT is able to detect the ventilation inhomogeneity.","PeriodicalId":102860,"journal":{"name":"2011 4th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123040746","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}

Recent studies show that retinal arteriolar and venular caliber change is associated with many cardiovascular risk factors. Thus, investigating blood column diameters inside retinal vessels during cardiac cycle (ECG gating) could help cardiologists in the prediction of cardiovascular disease. In this paper, we demonstrated an improved image preprocessing step for computer aided diagnosis algorithms that could be useful in measuring the width of the blood column. The algorithm consists of three main steps. First, higher resolution images at 21 megapixels were captured along with an inbuilt 570nm red-free filter to maximize the blood signal. Second, the image was decomposed using a Gabor filter at four different directions (0, 45, 90 and 135 degree) and maximum responses were obtained over the four directions. Finally, the size of vessels is calculated by performing the sliding linear regression filter (SLRF) on vessels slices. The results suggest the use of edge enhancement with SLRF decrease the variability by 2-3 times and might lead to more deterministic vessel widths with less variation.","PeriodicalId":102860,"journal":{"name":"2011 4th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116656642","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 DNA fragments of ag85b and mpb64 were fused by splicing by overlapping extension (SOE) polymerase chain reaction(PCR), and the fusion gene ag85b-mpb64 were cloned into pMD-18-T vector, then we got the recombinant plasmid pMD-85b-64. pMD-85b-64 and pET28a(+) were digested by BamH I and EcoR I double enzymes. The purified pMD-85b-64 fusion gene was subcloned into the expression vector pET28a(+), and the prokaryotic expression vector pET-85b-64 was constructed. Plasmid containing pET-85b-64 was transformed into competence Escherichia coli BL21 (DE3). The bacterium was induced by isopropyl-β-D-thiogalactopyranoside(IPTG) and its lysates were loaded directly onto sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), approximately 58 ku exogenous protein was observed on the SDS-PAGE. The protein was analyzed by using Western blotting, the results indicated that the protein was of antigenic activity of Mycobacterium bovis. These results could serve as a basis for further studies on the usefulness of the fusion gene and its expression product in the development of subunit vaccine and DNA vaccine against bovine tuberculosis.","PeriodicalId":102860,"journal":{"name":"2011 4th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116674483","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}
