BACKGROUND/AIMS Mounting evidence has shown that aberrant expression of miRNAs correlates with human cancers, and that miRNAs can function as tumor suppressors or oncogenes. Here, we investigated the role and mechanism of miR-142-3p in human osteosarcoma. METHODS We used quantitative real-time RT-PCR to measure the expression of miR-142-3p in human osteosarcoma cell lines and tissues. The rol...
We report on the selective area growth of N-polar GaN micrometer and sub-micrometer sized structures on structured sapphire wafers for applications in optical gas sensing. Optical lithography has been applied for patterning a SiO2-mask on the micrometer scale, whereas electron-beam lithography has been used on the nanometer scale. Subsequently, prismatically shaped GaN rods have been fabricated...
In this paper, the results of the Spherical Oil Agglomeration of Abstract .45 micrometer superpits low grade co al pa rticles (Bagworth Colliery, U.K.) within a su spension are prese nte d.Demineralized agglomerates were recovered directly by sieving on a 106 micrometer sieve. Verygood reductions in the ash content of the feed coal samples were achieved. In order to reducethe high levels of the...
