| 1 | Assessment of estrogen disrupting potency in animal foodstuffs of China by combined biological and chemical analyses显示文摘Food has been documented as one of major routes for human exposure to environmental estrogens(EEs), but information on the occurrence of EEs in animal foodstuffs is still scarce.This study analyzed estrogenic activity in 16 types of animal foodstuffs(n = 142) collected from four cities(Wuhan, Guangzhou, Wenzhou and Yantai) of China by combined yeast estrogen screen(YES) bioassay and chemical analysis. By bioassay, all samples' extracts were found to induce estrogenic activities and the bioassay-derived 17β-estradiol equivalent(EEQbio) ranged from 8.29 to 118.32 ng/g. In addition, the samples were analyzed by liquid chromatography coupled to tandem mass spectrometry for further chemical analysis. 17β-Estradiol was found in all samples in this survey at levels of 0.44 to 15.04 ng/g.All samples had 33.1% detection rate of 17α-ethinylestradiol(EE2), and the maximum concentration was 2.80 ng/g. Bisphenol A and 4-nonylphenols were detected in 83.8% and83.1% of samples, with concentrations up to 12.56 ng/g and 35.76 ng/g, respectively.However, the concentrations of estrone, diethylstilbestrol and 4-t-octylphenol were found to be below the limit of detection. A comparison of EEQbiomeasured from the YES assay and EEQchemcalculated from chemical analysis showed good correlation(R2= 0.84). Based on the results, the YES assay can be used as a rapid pre-screening method for monitoring the levels of estrogenic activity in large numbers of animal foodstuffs, and chemical analysis used in combination can be used for the identification of specific EEs. | Jun Wang Wei Xia Yonghua Xiao Chenjiang Ying Jia Long Hui Zhang Xi Chen Congda Mao Xiumin Li Lin Wang Shunqing Xu | 2014 | Journal of Environmental Sciences2014,26,10: | 4 |
| 2 | Entanglement charge of thermal states显示文摘Entanglement charge is an operational measure to quantify nonlocalities in ensembles consisting of bipartite quantum states.Here we generalize this nonlocality measure to single bipartite quantum states.As an example,we analyze the entanglement charges of some thermal states of two-qubit systems and show how they depend on the temperature and the system parameters in an analytical way. | YE MingYong LIN XiuMin BAI YanKui WANG ZiDan | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,4: | 2 |

| 4 | Unconventional quantum gate based on Rydberg blockade mechanism显示文摘We propose a scheme for realizing an unconventional three-qubit controlled-phase gate via the Rydberg blockade mechanism.The qubit is encoded by atomic ensembles that are trapped in optical traps and fixed on an atom chip.Because of the collective nature of the encoding and the Rydberg blockade mechanism,the scheme do not require separate addressing of individual atoms.The time needed for the gate operation is much shorter than that in a similar scheme.In addition,we show the gate can be used as a basic tool for effective generation of large-scale 2D cluster states. | SUN RongHui YE MingYong LIN XiuMin | 2013 | Science China(Physics,Mechanics & Astronomy)2013,56,9: | 1 |

| 6 | Classical information theory in quantum notations显示文摘Shannon's noisy channel coding theorem is a cornerstone in the history of classical information theory. A proof of Shannon's noisy channel coding theorem using quantum notations is presented, which sets up a bridge between classical information theory and the developing quantum information theory. | LI Gang YE MingYong LIN XiuMin | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,12: | 1 |

| 9 | Prokaryotic expression of recombinant human p75NTR-Fc fusion protein and its effect on the neurite outgrowth of dorsal root ganglia neuron显示文摘Objective: To clone, express, and identify the extracellular domain gene of human p75 neurotrophin receptor with IgG-Fc (hp75NTR-Fc) in prokaryotic expression system, and investigate the effect of the recombinant protein on dorsal root ganglia (DRG) neuron neurites. Methods: The hp75NTR-Fc coding sequence was amplified from pcDNA-hp75NTR-Fc by polymerase chain reaction (PCR) and subcloned into vector pET30a (+), in which hp75NTR-Fc expression was controlled under the T7 promoter. The recombinant vectors were amplified in E. coli DH5α and identified by PCR, enzyme digestion and sequencing, and then transformed into E. coli BL21 (DE3). The expression product was analyzed with SDS-PAGE and Western blot. Then after the recombinant protein purified with Protein A affinity chromatograph, and renaturated with dialysis, respectively, the effect of the recombinant protein on DRG neuron neuritis was further investigated. Results: The results of PCR, enzyme digestion, and sequencing demonstrated the success of inserting the hp75NTR-Fc fragment into vector pET30a (+). SDS-PAGE and Western blot showed a positive protein band with molecular weight about 50 kD in the expression product, which is accordant with the interest protein, and this band could be specifically recognized by rabbit anti-NGFRp75 antibody. The purified infusion protein following dialysis could promote neurite outgrowth of DRG neurons cultured with myelin-associated glycoprotein (MAG). Conclusion: The hp75NTR-Fc coding sequence was subcloned into the expression vector pET30a (+) correctly and expressed successfully in the prokaryotic expression system. The infusion protein could promote neurite outgrowth of DRG neurons cultured with MAG. | Zhu Feng Wang Yongtang Lu Xiumin Zeng Lin Wu Yamin | 2009 | Journal of Medical Colleges of PLA(China)2009,24,1: | 1 |
| 10 | Sodium-Calcium Exchanger-3 Plays Critical Roles in Pain'Wind-up'显示文摘Chronic pain,broadly described as pain lasting longer than 3 months,is a classic example of gene-environment interaction[1].A couple of types of chronic pain have also been shown to have complex heritable properties with a polygenic component[2].Quantitative Sensory Testing(QST)is a formal variant of the sensory examination,including'static'sensory profiling and'dynamic'QST.QST contributes to the prediction of vulnerable subpopulations and effective mechanisms.In addition,a deficit in dynamic QST has been proposed as a predictor of chronic pain[3]. | Lin Lin Xiumin Xue Zhihui Huang Yongjie Wang | 2023 | Neuroscience Bulletin2023,39,5: | 0 |
| 11 | Main Components and Antioxidant Activity of Callisia repens Extracts显示文摘To study the main active components and antioxidant activity in vitro of extracts from Callisia repens , the contents of main active components such as total flavonoids, total anthocyanin and total sugar in the extracts were studied by spectrophotometry. The components and content of 18 kinds of metals were determined by ICP-MS mass spectrometry. Finally, the oxidative activity of the extract was evaluated by spectrophotometry. Results showed that the content of flavonoids, the total protein, the total sugar and the total anthocyanin in C. repens extract powder were 2.04%, 1.83%, 55.2% and 7.2%, respectively. Beneficial trace elements such as Ca, Mn, Mg in C. repens extracts were higher, while harmful heavy metals such as Pb, Hg, Ag, Co, Ge were very tiny or not detected at all. The IC 50 of C. repens was 0.265 mg/mL for scavenging DPPH·, and 1.16 mg/mL for scavenging ·OH free radical, the total reducing power of 1 mg extract was equivalent to that of 39 μg of Vc, and the extract showed no regular chelating power to ferrous ions. In conclusion, C. repens extracts have high content of natural active components, but extremely low content of the harmful heavy metals, and C. repens extract has good antioxidant capacity. Its antioxidant activity is realized by a variety of active factors through a synergistic mechanism. Thus, C. repens extract has great potential for developing into functional foods. | Bo LENG Shaoru CAI Xiumin LI Jiafu HUANG Yu XUE Zhichao LIN Wensong CHEN Chunxian LI Yutian PAN | 2019 | Asian Agricultural Research2019,11,7: | 0 |
