Establishing murine models of hepatocellular carcinoma using NOD/SCID, nude and Balb/c mice: An initial comparative studyHistopathological results of the tumors showed that the development of hepatocellular carcinoma cells in the mouse models were accompanied by characteristics such as clumping of polymorphic cells, formation of an invasive strip, and establishment of a necrotic area inside the tumors. In addition, the cells showed an unequally divided nucleus a...

Secretory expression of the recombinant FGF-2 protein in Pichia pastoris carrying multiple copies of target geneAs a result, the yield of FGF-2 protein in this study was lower than other expression systems in previous studies of P. pastoris9,21, where the culture condition was optimized for methanol concentration, pH, and induction time. Therefore, the efficiency of the P. pastoris strain in this study could be improved by optimized shake-flask condition...

Evaluation of low energy X-Ray depth dose distribution by gafchromic film for dosimetry in food irradiationThe depth dose profile in the PMMA phantom is shown in Figure 5, and expressed in logarithm scale. As seen in the figure, the absorbed dose was almost attenuated within 30 mm thickness of the phantom. At 1.58 mm depth near the surface, the highest attenuation is observed; here, approximately 50% of the total attenuation was generated. After tha...
