Thus, in many practical applications simpler techniques which do not rely on complex transfer functions are employed. For example, Maximum Intensity Projection (MIP) which depicts the maximum value along each viewing ray. In this paper, we improve the Illustrative context-Preserving volume Rendering based on Visualization Toolkit (VTK). In our method, it can simultaneously visualize interior and exterior structures while preserving clear shape cues. The main limitation of MIP is that it cannot adequately depict the spatial relationships of overlapping tissues. An approach has been proposed to eliminate this drawback: Local Maximum Intensity Projection (LMIP). LMIP is an extended version of MIP. LMIP selects the first local maximum value encountered that is larger than a pre-selected threshold value along an optical ray from the viewpoint in the viewing direction. In this paper we propose an improved local maximum intensity projection. An appropriate threshold and shading are computed in this improved method. We show that the improved method is a useful technology in volumetric dataset visualization.

Method: The MSCs of rats were isolated and purified by whole bone marrow adherence and adherence screening method, the homology of the cells was analyzed by immunocytochemistry staining technique. The differential expression genes of MSCs treated with NC were analyzed by Affymetric whole genome gene chip analysis method. Result: Rat MSCs of higher purity (more than 90%) was acquired. After MSCs were treated with NC, 45 differential expression genes were displayed, the expressions of 21 genes among them were up-regulated (FC≥2) and the expressions of 24 genes were significantly down-regulated (FC≤-2).These genes included the genes participate in TGFβ / BMPs, Hedgehog, Bmp and Wnt signal transduction pathways that have relations with cell differentiation &development and /or nervous system function, and learning and memorizing functions, the genes of Ras and G protein-coupled receptor signaling pathways that have relations with cell growth and proliferation and apoptosis, and the genes of MAPKKK cascading. Conclusion: NC's anti-AD pharmacodynamic mechanism of molecular genes could have relations with numerous gene expressions of some signal transduction pathways, which participate in regulating nerve cell differentiation and development, nervous system function, functions of learning and memory, and common cell functions of growth, differentiation, proliferation and apoptosis.","PeriodicalId":263281,"journal":{"name":"2009 2nd International Congress on Image and Signal Processing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442131","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}
