| 1 | Dielectric properties of BiAlO3-modified (Na,K,Li)NbO3 lead-free ceramics显示文摘 | SUN Xiaojun DENG Jianming LIU Laijun | 2016 | Mater Res Bull2016，73，43： | 1 |
| 2 | Influence of interface point defect on the dielectric properties of Y doped CaCu_(3)Ti_(4)O_(12) ceramics显示文摘CaCu_(3)Ti_(4-x)Y_(x)O_(12)(0≤x≤0.12)ceramics were fabricated with conventional solid-state reaction method.Phase structure and microstructure of prepared ceramics were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM),respectively.The impedance and modulus tests both suggested the existence of two different relaxation behavior,which were attributed to bulk and grain boundary response.In addition,the conductivity and dielectric permittivity showed a step-like behavior under 405 K.Meanwhile,frequency independence of dc conduction became dominant when above 405 K.In CCTO ceramic,rare earth element Y^(3+)ions as an acceptor were used to substitute Ti sites,decreasing the concentration of oxygen vacancy around grainelectrode and grain boundary.The reason to the reduction of dielectric behavior in low frequencies range was associated with the Y doping in CCTO ceramic. | Jianming Deng Xiaojun Sun Saisai Liu Laijun Liu Tianxiang Yan Liang Fang Brahim Elouadi | 2016 | Journal of Advanced Dielectrics2016，6，1： | 0 |
| 3 | Neuroprotective effect of Eleutheroside B on 1-methyl-4-phenylpyridinium ion-induced apoptosis in PC12 cells显示文摘Apoptosis and viability of PC12 cells following 1-methyl-4-phenylpyridinium ion (MPP+)-induced injury were monitored by flow cytometry, following Annexin V-propidium iodide double labeling, and 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, respectively. The release of lactate dehydrogenase, superoxide dismutase activity and levels of malondialdehyde were determined by UV spectrophotometry. The changes in mitochondrial membrane potential and the intracellular concentration of calcium were determined by flow cytometry, and the activity of caspase-3 was monitored by western blot. According to cell viability and apoptosis studies, MPP+-induced apoptosis in PC12 cells was inhibited in the presence of 10 μg/mL of Eleutheroside B. Our results indicate that the neuroprotective effect of Eleutheroside B, following MPP+-induced apoptosis in PC12 cells, involves increasing the anti-oxidative stress capacity of cells, maintaining the high-energy state of mitochondrial membrane potential, reducing intracellular calcium concentration and inhibiting caspase-3 activity. | Fang Lu Yang Dong Laijun Deng Shumin Liu Shihui Zhou Lifeng An Bo Tang | 2011 | Neural Regeneration Research2011，6，18： | 0 |
