Nanorod-like TiO2 (nc-TiO2) and MoO3 (nc-MoO3) films were thermally grown from Ti- and Mo-metallic wafers. Nanohybrid films of N,N’-diphenyl-N,N’-bis(1-naphthyl)(1,1’-biphenyl)-4,4’diamine (NPB)/TiO2 and NPB/MoO3 used as anode/hole transport layer (HTL) heterojunctions in blue organic light emission diodes (OLEDs) were prepared by coating NPB onto the nc-TiO2 and nc-MoO3 and TiO2. Characterization of the nanostructured hybrid layers showed that both the photoluminescent property and current-voltage (I-v) characteristics of the hybrid materials were significantly enhanced in comparison with the standard NPB polymer. The electroluminous efficiency of the hybrid devices was considerably enhanced in comparison with the standard device. This suggests a useful application for fabricating “reverse” OLEDs, where the emission light goes-out through the semitransparent cathode, instead of the indium tin oxide (ITO) anode. For this, the ohmic contacts of conducting wires to metallic electrodes can be made much better than to ITO anodes.

Objective： To examinie the synergistic effects of Banxia Xiexin Decoction （半夏泻心汤, Known as Banhasasim-tang in Korean） extract （BXDE） on cisplatin-induced cytotoxicity in the A549 human lung cancer ceil lines. Methods： A549 cells were treated with varying concentrations （50-200μg/mL） of cisplatin and BXDE alone or in combination for 96 h. We used 1-（4,5-dimethylthiazol-2-yl）-3,5-diphenylformazan assay and flow cytometry to analyze cell viability and apoptosis, respectively. Results： The exposure of cells to cispiatin and BXDE alone or in combination decreased ceil viability dose- and time-dependently （P〈0.05）, which was found to be mediated by the apoptotic pathway as confirmed by the increase in the annexin v^＋/propidium iodide stained cell population and a ladder pattern of discontinuous DNA fragments. Furthermore, the apoptosis was inhibited by the pan-caspase inhibitor, benzyloxycarbonyI-val-Ala-Asp （OMe） fluoromethylketone （z-vAD-FMK）. Conclusions： BXDE significantly potentiated apoptotic effects of cisplatin in A549 cells. Moreover, apoptosis induced by BXDE might be the pivotal mechanism mediating its chemopreventative action against cancer.

Most rivers in vietnam flow directly to the sea where the interaction between fresh and salt water occurs. Because of uneven flow distribution through the year with only 20% annual flow in the dry season, while fresh water requirement for socio-economic activity in this season is much higher. With this situation, the simulation and finding out the mechanism of saline water intrusion into the estuary in general will help to suggest suitable solutions to control the situation. This paper presents results done at the Huong river estuary. Based on the data collected in current years and using MIKE11 softwave, number scenarios were simulated and found out the intruded process of saline water into the river. They will be very important parameters for which solutions to control negative effects to serve socio-economic development at the downstream of Huong river will be recommended and implemented in the later stage.
