Internal erosion is one of the important causes of soil damage. In this paper, an erosion-stress coupling apparatus was developed to investigate the mechanical property of soil after internal erosion. Main efforts were devoted to rebuilding pressure cell so that soils can be eroded under confining pressure and deviator pressure. The hydraulic gradient is controlled by using the water-head control method which can provide up to 40 m water-head. The volume change of the sample can also be accurately measured by the volume controller. The eroded particles were collected by the eroded soil collection system. Triaxial consolidation drained shear tests after internal erosion were performed on gap graded soils. It was found that the drainage failure strength and drainage internal friction angle of soil after internal erosion under confining pressure decreased with the increase of fine particle loss. Based on the experimental data, amodified Duncan-Chang model considering fine particle loss was introduced. Numerical modelling of vertical displacement of dam was carried out by using the modified Duncan-Chang model, and it was found that when the fine particle loss exceeds 10%, the displacement increases significantly.

Transient receptor potential melastain 7 (TRPM7) is a bifunctional protein with dual structure of both ion channel and protein kinase, participating in a wide variety of diseases including cancer. Recent researches have reported the mechanism of TRPM7 in human cancers. However, the correlation between TRPM7 and prostate cancer (PCa) has not been well studied. The objective of this study was to investigate the potential the role of TRPM7 in the apoptosis of PC-3 cells, which is the key cell of advanced metastatic PCa. In this study, we demonstrated the influence and potential function of TRPM7 on the PC-3 cells apoptosis induced by TNF-related apoptosis inducing-ligand (TRAIL). The study also found a novel up-regulated expression of TRPM7 in PC-3 cells after treating with TRAIL. Suppression of TRPM7 by TRPM7 non-specific inhibitors ($Gd^{3+}$ or 2-aminoethoxy diphenylborate (2-APB) ) not only markedly eliminated TRPM7 expression level, but also increased the apoptosis of TRAIL-treated PC-3 cells, which may be regulated by the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway accompany with up-regulated expression of cleaved Caspase-3, (TRAIL-receptor 1, death receptors 4) DR4, and (TRAIL-receptor 2, death receptors 5) DR5. Taken together, our findings strongly suggested that TRPM7 was involved in the apoptosis of PC-3 cells induced by TRAIL, indicating that TRPM7 may be applied as a therapeutic target for PCa.

Seroprevalence of Toxoplasma gondii Among Primary School Children in Shandong Province, China

Although Toxoplasma gondii infection in primary school children has been investigated in many countries, limited surveys have been available in primary school children in China. In the present study, we report the seroprevalence of T. gondii infection in primary school children in Shandong province, China. Sera from 6,000 primary school children were evaluated for T. gondii antibodies with ELISA. The overall seroprevalence of T. gondii infection was 16.0% (961/6,000), of which 14.5% (870/6,000) were positive for anti-T. gondii IgG antibodies, 3.4% (206/6,000) positive for IgM, and 1.9% (115/6,000) were positive for both IgG and IgM. The results of the present investigation indicated a high seroprevalence of T. gondii infection in primary school children in Shandong province, China. Therefore, effective measures should be taken to prevent and control T. gondii infection in primary school children in this province. To the best of our knowledge, this is the first report of T. gondii seroprevalence in primary school children in Shandong province, China.
