By combining scanning tunneling microscopy and spectroscopy, angle-resolved photoemission spectroscopy, and density functional theory band calculations, we directly observe and resolve the one-dimensional edge states of single bilayer (BL) Bi(111) islands on clean Bi(2)Te(3) and Bi(111)-covered Bi(2)Te(3) substrates. The edge states are localized in the(More)
(-)-Epigallocatechin-3-O-gallate(EGCG), the highest catechins from green tea, has promisingly been found to sensitize the efficacy of several chemotherapy agents like doxorubicin (DOX) in hepatocellular carcinoma (HCC) treatment. However, the detailed mechanisms by which EGCG augments the chemotherapeutic efficacy remain unclear. Herein, this study was(More)
Using the intracellular recording techniques of toad paravertebral ganglia (PVG), the effects of cholinesterase inhibitor huperzine A (Hup-A), an alkaloid first isolated from Huperzia serrata (Thunb) Trev in China, on the synaptic transmission were studied. In 30 PVG cells tested, no remarkable changes in membrane potential and input resistance were(More)
Tartary buckwheat (Fagopyrum tataricum Gaertn) has been praised as one of the green foods for humans in the 21st century. Effects of fertilization on leaf photosynthetic characteristics and grain yield of tartary buckwheat has not been reported in detail. Our experiment was set as a split-plot factorial. The main plots and subplots were designed by(More)
Published studies on the association between NCF4 rs4821544T/C polymorphism and inflammatory bowel disease (IBD) risk in Caucasian have yielded conflicting results. The present study aimed to provide more reliable conclusions by conducting a meta-analysis. All eligible studies were extracted from Wiley Online Library, Chinese National Knowledge(More)
Bacillus nematocida B16 is able to dominate in the intestines of the worm Caenorhabditis elegans in 'Trojan horse' pathogenic mechanism. The adp is one candidate gene which potentially play a vital role in the colonization from our previous random mutagenesis screening results. To analyse the functional role of this gene, we constructed the adp knockout(More)
AIM To evaluate the predictive value of RRM1, ERCCl, and BRCA1 expression in Chinese NSCLC patients treated with gemcitabine and cisplatin. METHODS Real-time fluorescent quantitative PCR was used to determine the RRM1, ERCC1, and BRCA1 mRNA expression levels of peripheral blood in late-stage NSCLC patients. The relationship between peripheral blood and(More)

We report the detections of the anti-correlated soft and hard X-rays, and the time lags of ∼ hecto-second from the neutron star low-mass X-ray binary Cyg X-2, a well-known Z-type luminous source. Both the anti-correlation and the positive correlation were detected during the low-intensity states, while only the latter showed up during high-intensity states.(More)

We have carried out detailed analysis on the black hole candidate (BHC) X-ray transient Swift J1753.5−0127 observed by the Rossi X-Ray Timing Explorer (RXTE) during its outburst in 2005 – 2006. The spectral analysis shows that the emissions are dominated by the hard X-rays, thus revealing the low/hard state of the source during the outburst. The peak(More)
