Object semantic reduces the semantic gap in Content Based Image Retrieval (CBIR). In recent years, numerous methods for object semantic categorization have been proposed. Semantic segmentation is a key factor affecting the accuracy of object semantic categorization. The existing semantic segmentation methods usually chose pixel or super-pixel as the processing input. But the information contained...
In order to find sensitive drugs in the radiotherapy of human breast cancer, some experiments were done to detect autophagy and apoptosis on MCF7 cells. MTT method detected cells proliferation; flow cytometry detected cells apoptosis; real-time PCR method analyzed the relative expression amounts of mRNAs. Results showed cells proliferation reduced with the extension of irradiation and apoptosis increased...
Wnt / β-catenin signaling pathway play an important role in the development of tumor. Here we try to study its role in tumor through investigating the expressions of β-catenin, c-myc and cyclin D1 in thymic lymphomas of mice induced by ionizing radiation. The mouse model of thymic lymphomas induced by irradiation was made according to the Kaplan' method. The mice were killed and the thymus were removed...
