On the basis of previous study,in which two target sequences with favorable RNAi effect on HER2 were identified, a series of dual promoter siRNA-expressing vectors containing two opposing U6 and H1 promoters were constructed. After transfection of HER2-overexpressing SKBR3 breast cancer cells with the siRNA-expressing vectors, downregulation of HER2 was identified quantitatively.
Calculating with the molar absorption coefficient[38000 L/(mol·cm~2)]of Maldener et al. (2001)shows that the“water”contents in rutiles are 324 to 523×10~(-6),which is greatly lower than the previous researcher's result calculated with the molar absorption coefficient[3270 L/(mol·cm~2)]of Hammer et al. , (1991).
On the basis of previous researches and the quantitative remote sensing results, in this paper the variability trend of NDVI from 1982 to 2004 in Ningxia area is studied by using GIMMS NDVI data and MODIS data.
The results show that the interfacial tension between CaO-Al2O3 slag melt and Fe-Ni alloy melt is consistent with the previous results
The zircon SHRIMP U-Pb dating results suggest that the Qiongzhong and Danxian granites were emplaced at 237 3 Ma and 186 3 Ma, respectively, which argued against the previous thoughts that all the foliated granites with orientated structure in Hainan Island formed duing the Hercynian - Indosinian episode.
In our previous work, anionic poly(styrene-acrylic acid) (PSA-A) with a lot of COO- groups covering on its surface was prepared using Poly(C9-acrylic acid) (P(C_9-AA)) as emulsifier and it was used as template for preparing CdS, ZrO_2 hollow spheres and Ag/TiO_2, CdS/TiO_2 composite hollow spheres.
On the basis of the Franck-Condon factor consideration, the IE of (10.43±0.02) eV determined in the previous single-photon ionization experiment most likely corresponds to the ionization threshold for the H_2CCC→H_2CCC~+(~2A_1, C_(2v)) transition.
From the reflection spectrum of PbMo6S8 the charge transfer from Mo6S8 cluster to Pb atom is calculated to be 1.18 instead of 2 electrons being transferred from Pb atom to Mo6S8 cluster as generally recognized in previous literatures.
Results show that the positive rate of three tests are 56. 3% ,21. 9% and 43. 8% seperately before operation, which is approximate to our previous random study on vasectomized men(52. 1%,23. 9% and 27. 4%).
The fiberization of affine systems via dual Gramian techniques, which was developed in previous papers of the authors, is applied here for the study of affine frames that have an affine dual system.
Our proofs proceed in the time domain and allow us to represent each solution regardless of the spectral radius of P(0):=2-s∑cα, which has been a difficulty in previous investigations of this nature.
Another generalization is obtained in the context of representations of Jordan algebras, in the spirit of Herz's previous work on matrix spaces.
This has significant advantages over the previous work.
The article extends upon previous work by Temlyakov, Konyagin, and Wojtaszczyk on comparing the error of certain greedy algorithms with that of best m-term approximation with respect to a general biorthogonal system in a Banach space X.
