Stimulated Raman scattering microscopy with phase-controlled light focusing and aberration correction for rapid and label-free, volumetric deep tissue imaging

2013教育技术与信息系统国际会议

作者： tan weiqi Anqing Vocational and Technical College

Occupational ability consists of three levels according to the theory of system composition: special professional skills, industry generic skills and core skills. Analytic hierarchy process is used to establish the hierarchical structure model, construct the comparison matrix, calculate the weights of the factors and test the consistency. The factors influencing the fuzzy judgment matrix can be determined by using fuzzy evaluation method. Scores of the affecting factors can be got reversely, which provides the basis for the judgment of the students’ occupational ability levels and the affecting factors. Using fuzzy level evaluation to evaluate occupational ability of higher vocational students provides a new method for occupational ability evaluation.

AIM: To determine the expression of micro RNA-210(mi R-210) in hepatocellular carcinoma(HCC) and to examine its role using HCC ***: The expression of mi R-210 was determined in 21 pairs of HCC samples and the corresponding surrounding non-tumor tissues. The effects of mi R-210 on proliferation and cell cycle progression were examined using Hep G2 and Hu H7 cells. Overexpression and inhibition of mi R-210 was achieved by transfection of the cells with mi R-210 mimic or inhibitor. Luciferase reporter constructs were used to identify the mi R-210 interacting site on Yes1. Yes1 expression was examined after mi R-210 transfection,as well as in the HCC ***: mi R-210 was significantly up-regulated by 3.4 fold(P < 0.01) in the tumor samples. The over-expression of mi R-210 significantly reduced cell proliferation compared to the mock-treated cells(68.9% ± 7.4% and 53.6% ± 5.0%,P < 0.05 for the Hep G2 and Hu H7 cells respectively). Analysis of the Hu H7 cells transfected with mi R-210 mimic by flow cytometry showed that the cells took a longer time to reach the G2/M phase. The interaction between mi R-210 and the 3'UTR of the Yes1 transcript was confirmed using a luciferase reporter assay. Over-expression of mi R-210 reduced the expression of Yes1 protein in both Hu H7 and Hep G2 cells. Tumors with a greater than fourfold increase in the expression of mi R-210 showed consistently lower expressions of Yes1 in the *** nocodazole-treated cells with a significant G2/M cell population,Yes1 protein was significantly reduced and pre-inhibition of mi R-210 in Hu H7 cells was able to prevent the reduction of Yes1 protein expression. Knock-down of Yes1 by si RNA also led to reduced cell proliferation(70.8% ± 7.5%,P < 0.05 in the Hu H7 cells).CONCLUSION: Up-regulation of mi R-210 inhibits cell proliferation. Yes1 is a target of mi R-210 and affects cell proliferation in HCC.

The melting process of solid-liquid phase change materials(PCM)has a significant impact on their energy storage *** more effectively apply solid-liquid PCM for energy storage,it is crucial to study the regulation of melting process of solid-liquid PCM,which is numerically investigated based on double multiple relaxation time lattice Boltzmann method(MRT-LBM)in this *** this work we pay more attention to the effects of different Stefan numbers(Ste)and Rayleigh numbers(Ra)on the melting *** results indicate that the PCM melting is greatly influenced by the Ste number and Ra number,which can be divided into the heat conduction dominant stage and the convection dominant stage,according to the onset time of convection Fo_(C).In order to describe the contribution of the heat conduction dominant stage to the whole melting process quantitatively,we firstly propose the ratio of the heat conduction dominant stage R_(pc),which can be defined as the ratio of Fo_(C)to the complete melting time Fo_(M).R_(pc)gradually decreases as the Ra number increases,and when the Ste number rises:R_(pc)=90.0%when Ste=1.0 and Ra=1×10^(5),R_(pc)=39.6%when Ste=0.1 and Ra=1×10^(5),and R_(pc)=14.0%when Ste=1.0 and Ra=1×10~7.A regime map about the effects of different Ste numbers and Ra numbers on R_(pc)has been further *** discovered findings would be helpful in regulating melting process in the energy storage of solid-liquid PCM.
