Unsaturated alcohols are important components in complex mixtures of oxygenated volatile organic compounds,and play a significant role in atmospheric *** uptake kinetics of 3-buten-l-ol(B031),4-penten-1-ol(P041) and 3-methyl- 3-buten-1-ol(MB0331) into 2. wt%-80 wt%HSO solutions were studied,using a rotated wetted-wall reactor coupled to a differentially pumped single-photon ionization time of flight mass spectrometer(SPI-TOFMS).With increasing acidity,the uptake processes changed from reversible to irreversible(reactive).Reactive uptake was observed in 60 wt%-80 wt%,50 wt%-80 wt% and 30 wt%-80 wt%HSO solutions for B031,P041 and MB0331,*** uptake coefficients were acquired and are reported here for the first *** order followed the trend:B031

The fluorescent spectra of 2. 6-bis(benzimidazol-2.yl) pyridine (compound 2. and its N-substituted compound (1) arestudied. The fluorescent characteristics of these compounds and the complexes formed from these compounds with different metal ionshave also been investigated. The results show that compound 1 possesses a specific ability to form complex with Cu2.ions, but compound2.has not such a property. It is proposed that the specific recognition ability of compound 1 to Cu2.may attribute to the cyclic configura-tion of this compound in polar solvent.

Wnt signaling plays an important role in embryogenesis and tumorgenesis. Although the mechanism about how Wnts transduce their signaling from receptor frizzled (Fz) to cytosol has not been understood, dishevelled (Dvl) protein was considered as the intersection of Wnt signal traffic. In this study, we characterized the function of three domains (DIX, PDZ and DEP) of Dvl-1 in canonical Wnt signal transduction and Dvl-1 membrane translocation. It was found both DIX and DEP domain were sufficient to block Wnt-3a-induced LEF-1 transcriptional activity and free cytosol β-catenin accumulation; whereas PDZ domain and a functional mutant form of DEP domain (DEP-KM) had no effect on canonical Wnt signaling. In addition, when cotransfected with Fz-7, DEP domain, but not DIX, PDZ or DEP-KM, translocated and co-localized with Fz-7 to the plasma membrane, which was similar to Dvl-1. Furthermore, it was DEP domain that could block Fz-7-induced membrane translocation of Dvl-1 via a possible competitive mechanism. Thes

[Objective] The research aimed to establish the regression model which was used to predict the precipitation in the flood season in china.[Method] Based on statistical model,North Atlantic oscillation index and the sea surface temperature index in development and declining stages of ENSO were used to predict East Asian summer monsoon *** the stations were divided into 16 zones,the same factors were used to establish the regression model predicting the station precipitation in the flood season in ***,it was compared with the model that predicted firstly the monsoon index and estimated the precipitation.[Result] The prediction results of summer precipitation during 2.05-2.09 by every model were *** was found that the model that the factor predicted indirectly the regional precipitation was better than that predicted indirectly the station ***,the model that the factor predicted directly the regional precipitation was better than that predicted indirectly the regional *** prediction score P of optimum model that three factors predicted directly the regional precipitation reached averagely 74.2.and the anomaly correlation coefficient ACC was averagely *** from the comparison situation of positive and negative zone distribution of precipitation anomaly percentage between the predicted and observed values in 5 years,the prediction effects in the south and east of Northeast china,some areas in the south of Yangtze River,the coast of South china and most areas of Xinjiang were *** predicted positive/negative distribution of precipitation anomaly percentage tallied with that of observation.[Conclusion] The model could predict well summer precipitation in china.
