The Analysis of Transition in Woman Social Status—Comparing Cinderella with Ugly Betty
Tiping Su,Qinyi Xue
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.5.746-752
Abstract: Cinderella, a perfect fairly tale girl has been widely known to the world. Its popularity reveals the universal Cinderella Complex hidden behind the woman status. My thesis focuses its attention on the transition in woman status. First, it looks into the Cinderella paradigm as well as its complex in reality. Second, it finds the transcendence in modern Cinderella. The last part pursues the development of women status’ improvement. In current study, seldom people make comparisons between Cinderella and Ugly Betty. With its comparison and the exploration of feminism, it can be reached that woman status have been greatly improved under the influence of different factors like economic and political. And as a modern woman lives in the new century, she has to be independent in economy and optimistic in spirit.

Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.22020
Abstract: Aiming at solving the problem that big differ-ence exists between logging permeability and true permeability of micro-fractured low-permeability sand reservoir, this paper puts forward a new method to revise logging per-meability by using primiparity data of oil field. This method has been successfully applied to revise logging permeability of micro-fractured low-permeability sand reservoir in Baiyushan area of Jing’An oil field, which shows that the method is reliable because the geological model building through the permeability which has been handled by this method accords with the real reservoir significantly.

Abstract: XopN is a type III effector protein from Xanthomonas campestris pathovar vesicatoria that suppresses PAMP-triggered immunity (PTI) in tomato. Previous work reported that XopN interacts with the tomato 14-3-3 isoform TFT1; however, TFT1's role in PTI and/or XopN virulence was not determined. Here we show that TFT1 functions in PTI and is a XopN virulence target. Virus-induced gene silencing of TFT1 mRNA in tomato leaves resulted in increased growth of Xcv ΔxopN and Xcv ΔhrpF demonstrating that TFT1 is required to inhibit Xcv multiplication. TFT1 expression was required for Xcv-induced accumulation of PTI5, GRAS4, WRKY28, and LRR22 mRNAs, four PTI marker genes in tomato. Deletion analysis revealed that the XopN C-terminal domain (amino acids 344–733) is sufficient to bind TFT1. Removal of amino acids 605–733 disrupts XopN binding to TFT1 in plant extracts and inhibits XopN-dependent virulence in tomato, demonstrating that these residues are necessary for the XopN/TFT1 interaction. Phos-tag gel analysis and mass spectrometry showed that XopN is phosphorylated in plant extracts at serine 688 in a putative 14-3-3 recognition motif. Mutation of S688 reduced XopN's phosphorylation state but was not sufficient to inhibit binding to TFT1 or reduce XopN virulence. Mutation of S688 and two leucines (L64,L65) in XopN, however, eliminated XopN binding to TFT1 in plant extracts and XopN virulence. L64 and L65 are required for XopN to bind TARK1, a tomato atypical receptor kinase required for PTI. This suggested that TFT1 binding to XopN's C-terminal domain might be stabilized via TARK1/XopN interaction. Pull-down and BiFC analyses show that XopN promotes TARK1/TFT1 complex formation in vitro and in planta by functioning as a molecular scaffold. This is the first report showing that a type III effector targets a host 14-3-3 involved in PTI to promote bacterial pathogenesis.

Abstract: We report the discovery of a Compton-thick Active Galactic Nucleus (AGN) at z=4.76 in the 4 Ms Chandra Deep Field South. This object was selected as a V-band dropout in HST/ACS images and previously recognized as an AGN from optical spectroscopy. The 4 Ms Chandra observations show a significant (~4.2sigma) X-ray detection at the V-band dropout position. The X-ray source displays a hardness ratio of HR=0.23+-0.24, which, for a source at z~5, is highly suggestive of Compton-thick absorption. The source X-ray spectrum is seen above the background level in the energy range of ~0.9-4 keV, i.e., in the rest-frame energy range of ~5-23 keV. When fixing the photon index to Gamma=1.8, the measured column density is N_H=1.4^{+0.9}_{-0.5} x 10^{24} cm^{-2}, which is Compton-thick. To our knowledge, this is the most distant heavily obscured AGN, confirmed by X-ray spectral analysis, discovered so far. The intrinsic (de-absorbed), rest-frame luminosity in the 2-10 keV band is ~2.5 x 10^{44} erg s^{-1}, which places this object among type-2 quasars. The Spectral Energy Distribution shows that massive star formation is associated with obscured black hole accretion. This system may have then been caught during a major co-eval episode of black hole and stellar mass assembly at early times. The measure of the number density of heavily obscured AGN at high redshifts will be crucial to reconstruct the BH/galaxy evolution history from the beginning.
Inhibition of Radiation-Induced Lung Adenocarcinoma Cell Metastasis by Adenovirus of PIAS3 Overexpression Driven by Radiation-Inducible Promoter (Ad-pig3RRP-PIAS3)  [PDF]

Abstract: Radiotherapy is one of important approaches for pulmonary adenocarcinoma. However, many studies have shown that radiation can also enhance the ability of tumor cells metastasis, although the lung adenocarcinoma could be killed. The increased metastasis induced by radiation is associated with the activation of STAT3 in lung adenocarcinoma cells. Based on the importance role of STAT3 in cell proliferation and survival, we can construct an adenovirus vector of PIAS3 overexpress driven by radiation-induced promoter to inhibit the activation of STAT3 specifically. In this way, when STAT3 was activated by radiation, the expression of PIAS3 will be increased at the same time; this lead to the inhibition of invasion and metastasis caused by STAT3 in lung adenocarcinoma cells. These researches are expected to develop a novel target and method for radiotherapy and molecular therapy of lung adenocarcinoma.
First-Principles Study on Cation-Antisite Defects of Stannate and Titanate Pyrochlores  [PDF]

Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100516
Abstract: The structure and formation energies of cation antisite defects for a series of stannate pyrochlores A2Sn2O7 (A = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Lu, and Y) and titanate pyrochlores A2Ti2O7 (A = La, Sm, Gd, Tb, Dy, Ho, Er, Lu, and Y) have been systematically investigated using the first-principles total energy calculations. The calculated results reveal that the lattice parameters increase and the oxygen positional parameters decrease with increasing ionic radii of the lanthanides in the stannate and titanate pyrochlore compounds, respectively. The results suggest that cation antisite defects in pyrochlore play an important role in determining their radiation-resistant properties. The present studies indicate formation energies of cation antisite defects are not simple functions of ionic radius, radius ratio, lattice parameters, and the oxygen positional parameters.

Abstract: Following Schistosoma japonicum (S. japonicum) infection, granulomatous responses are induced by parasite eggs trapped in host organs, particular in the liver, during the acute stage of disease. While excessive liver granulomatous responses can lead to more severe fibrosis and circulatory impairment in chronically infected host. However, the exact mechanism of hepatic granuloma formation has remained obscure. In this study, we for the first time showed that follicular helper T (Tfh) cells are recruited to the liver to upregulate hepatic granuloma formation and liver injury in S. japonicum-infected mice, and identified a novel function of macrophages in Tfh cell induction. In addition, our results showed that the generation of Tfh cells driven by macrophages is dependent on cell–cell contact and the level of inducible costimulator ligand (ICOSL) on macrophages which is regulated by CD40–CD40L signaling. Our findings uncovered a previously unappreciated role for Tfh cells in liver pathology caused by S. japonicum infection in mice.

Abstract: Based on the pentad mean ridgeline index of the western Pacific subtropical high (WPSH), the authors identified the two northward jumps of the WPSH from 1979 to 2008 and revealed their associations with the tropical SST anomalies. The authors show that the northward jumps, especially the second jump, exhibited remarkable interannual variability. In addition, the authors find that the two northward jumps were mutually independent and were influenced by the SST anomalies in the different regions of the tropical Pacific. The first jump was positively correlated with the SST anomalies in the tropical central Pacific from the preceding winter to June. In contrast, the second jump was positively related to ENSO in the preceding winter, but this correlation tended to weaken with the decay of ENSO and disappeared in July. Instead, a positive correlation was found in the Indian Ocean. We therefore suggest that ENSO plays an indirect role in the second jump through the capacitor effect of the Indian Ocean.
