The rechargeable Li-CO2 battery has attracted much attention for energy storage because of the high energy density and efficient utilization of greenhouse gas. However, it＇s still suffered by low safety issue of liquid electrolyte. Herein, a composite cathode consisting of CNTs and polymer electrolytes was fabricated by the insitu polymerization process for the polymer electrolyte-based solid-state Li-CO2 batteries. With the good dispersion of CNTs and polymer electrolyte, the composite cathode is covered by film-like discharge products ***, the Li-CO2 battery shows high reversible capacity （- 11,000 mAh·g^-1）, excellent cycle stability （1000 mAb·g^-1 for 100 cycles） under low charge potential （〈 4.5 V）, and outstanding rate performances at room temperature, which are much better than those of liquid electrolyte-based battery. Therefore, the polymer electrolyte-based Li-CO2 battery prepared by this strategy can be a promising candidate to meet the demands of high safety and high-performance energy storage devices.

AIM： To determine the inhibitory effect of the vectorgenerated small interfering RNAs （siRNAs） on the expression of the BcI-XL gene in established human esophageal cancer cells, and to investigate the effect of the BcI-XL siRNAs on cell growth and apoptosis in esophageal cancer cells. METHODS： Three siRNA-expressing vectors targeting different sites of the Bcl-XL gene were constructed from pTZ-U6＋I vector. Cultured esophageal cancer cells were transfected with the siRNA-expressing vector （or the control vector） using lipofectamine 2000. BcI-XL gene expression was determined with semiquantitative RT- PCR assay and Western blotting. Among the three siRNA- expressing vectors, the most highly functional vector and its effect on cell growth and apoptosis in esophageal cancer ceils was further analyzed. RESULTS： Of the three siRNA-expressing vectors, siRNA- expressing vector No.1 was the most potent one which suppressed Bcl-XL mRNA production to 32.5% of that in the untreated esophageal cancer cells. Western blotting analysis showed that siRNA-expressing vector No.1 markedly down-regulated the expression of Bcl-XL in human esophageal cancer cells. Treatment of esophageal cancer cells with siRNA-expressing vector No.1 resulted in inhibition of cell growth and induction of apoptosis. CONCLUSION： Down-regulation of BcI-XL by vectorgenerated small interfering RNAs can suppress cell growth and induce apoptosis in human esophageal cancer cells.

The waxy （wx） locus of Zea mays L. encodes a granule-bound starch synthase （GBSS I = waxy protein） required for the synthesis of amylose in endosperm and pollen grain. This review covers recent advances in understanding the waxy locus in maize, focusing particularly on the new information on mutant type and mutation mechanisms. The results showed that the insertion and deletion played an important role in the generation of spontaneous wx-mutations. The current status of utilizing waxy locus has been summarized and the perspectives of the further studies on this locus have also been proposed.

One major goal of mesh parameterization is to minimize the conformal distortion. Measured boundary parameteri-zations focus on lowering the distortion by setting the boundary free with the help of distance from a center vertex to all the boundary vertices. Hence these parameterizations strongly depend on the determination of the center vertex. In this paper,we introduce two methods to determine the center vertex automatically. Both of them can be used as necessary supplements to the existing measured boundary methods to minimize the common artifacts as a result of the obscure choice of the center vertex. In addition,we propose a simple and fast measured boundary parameterization method based on the Poisson's equation. Our new approach generates less conformal distortion than the fixed boundary methods. It also generates more regular domain boundaries than other measured boundary methods. Moreover,it offers a good tradeoff between computation costs and conformal distortion compared with the fast and robust angle based flattening (ABF++).

Radiative energy losses are very important in regulating the cosmic ray electron and/or positron(CRE) spectrum during their propagation in the Milky Way. Particularly, the Klein–Nishina(KN) effect of the inverse Compton scattering(ICS) results in less efficient energy losses of high-energy electrons, which is expected to leave imprints on the propagated electron spectrum. It has been proposed that the hardening of CRE spectra around 50 GeV observed by Fermi-LAT, AMS-02, and DAMPE could be due to the KN effect. We show in this work that the transition from the Thomson regime to the KN regime of the ICS is actually quite smooth compared with the approximate treatment adopted in some previous works. As a result, the observed spectral hardening of CREs cannot be explained by the KN effect. It means that an additional hardening of the primary electrons spectrum is needed. We also provide a parameterized form for the accurate calculation of the ICS energy-loss rate in a wide energy range.

A new water-soluble hetero-polysaccharlde, APSID3, was obtained from a hot-water extract of the roots of Astragalus membranaceus （Flsch.） Bunge by DEAE-Sepharose Fast Flow and Sephacryl S-300 chromatography. The molecular weight of APSID3 was estimated to be 5.79 × 10^5 Da. Based on a sugar composlUon analysis, methylatlon analysis, partial hydrolysis and 13C nuclear magnetic resonance experimentation, It was concluded that the minimal repeat unit of APSID3 was composed of one terminal arablnose, one 1,5-1Inked arabinose, one 1,3-1Inked rhamnose, one 1,3,4-1Inked rhamnose, five 1,4-1Inked methyl galacturonates and six 1,4-1inked methyl glucuronates.
