| 1 | Precipitation behavior and properties of extruded 7136 aluminum alloy under different aging treatments显示文摘In this work, the mechanical properties and electrical conductivity of the extruded 7136 aluminum alloy treated by single-stage aging treatment(T6), retrogression and re-aging treatment(RRA), and multiple retrogression and re-aging treatment have been investigated by means of hardness measurements, electrical conductivity tests and tensile tests. The results have shown that the properties of the 7136 alloy such as hardness, tensile strength and electrical conductivity were sensitive to retrogression time(within 90 min). With prolonging the retrogression time, the tensile strength was enhanced first and then decreased, yet the electrical conductivity was continuously increased. The 60 min-treated alloy performed the highest tensile strength(716 MPa), whereas the 90 min-treated alloy possessed the highest electrical conductivity(33.95%IACS). Compared with the T6-treated alloy, the tensile strength and electrical conductivity were improved by 3.3%and 18.9%, respectively. The electrical conductivity showed an obvious increase with repetitious times of the RRA treatment. After 3 RRA60 treatment, a good combination of tensile strength(705 MPa) and electrical conductivity(33.20%IACS) can be obtained. Compared with the T6 condition, the tensile strength and electrical conductivity were improved by 1.7% and 16.3%, respectively. The mechanism of microstructure evolution under different aging treatments has been discussed in detail. | Huiyan LI Lina JIA Jiangnan HUANG Yue MA | 2021 | Chinese Journal of Aeronautics2021，34，2： | 6 |
| 2 | Cow, yak, and camel milk diets differentially modulated the systemic immunity and fecal microbiota of rats显示文摘Cow milk is most widely consumed; however,non-cattle milk has gained increasing interest because of added nutritive values. We compared the health effects of yak,cow,and camel milk in rats. By measuring several plasma immune factors,significantly more interferon-c was detected in the camel than the yak(P = 0.0020) or cow(P = 0.0062) milk group. Significantly more Ig M was detected in the yak milk than the control group(P = 0.0071). The control group had significantly less interleukin 6 than the yak(P = 0.0499)and cow(P = 0.0248) milk groups. The fecal microbiota of the 144 samples comprised mainly of the Firmicutes(76.70 ± 11.03%),Bacteroidetes(15.27 ± 7.79%),Proteobacteria(3.61 ± 4.34%),and Tenericutes(2.61 ± 2.53%) phyla. Multivariate analyses revealed a mild shift in the fecal microbiota along the milk treatment. We further identified the differential microbes across the four groups. At day 14,22 and 28 differential genera and species were identified(P = 0.0000–0.0462),while 8 and 11 differential genera and species(P = 0.0000–0.0013) were found at day 28. Some short-chain fatty acid and succinate producers increased,while certain health-concerned bacteria(Prevotella copri,Phascolarctobacterium faecium,and Bacteroides uniformis) decreased after 14 days of yak or camel milk treatment. We demonstrated that different animal milk could confer distinctive nutritive value to the host. | Yongping Wen Qiuwen He Jia Ding Huiyan Wang Qiangchuan Hou Yi Zheng Changkun Li Yuzhu Ma Heping Zhang Lai-Yu Kwok | 2017 | Science Bulletin2017，62，6： | 4 |
| 3 | The role of MAPK and FAS death receptor pathways in testicular germ cell apoptosis induced by lead显示文摘现在的学习的目的是调查在阴囊的细菌房间的导致铅的 apoptosis 涉及 MAPK 的信号小径和船边交货的死亡信号受体小径的基因表示。首先,房间生存能力被 MTT 试金决定。第二,使用单个房间胶化电气泳动测试(彗星试金) 和染色技术, apoptotic 率和阴囊的细菌房间的房间 apoptosis 本地化的 TUNEL 在分别地与 0.15% , 0.3% ,和 0.6% 铅一起对待的老鼠被测量。第三, K 地岬, c-fos,船边交货,和活跃 caspase-3 蛋白质的 immunolocalization 被 immunohistochemistry 决定。最后,在 K 地岬, c-fos,船边交货,和活跃 caspase-3 的翻译层次的变化被西方的污点分析进一步检测。我们的结果证明铅能显著地以一种剂量依赖者方式导致阴囊的细菌房间 apoptosis (P < 0.01 ) 。机制是仔细与在 apoptotic 细菌房间的 K 地岬, c-fos,船边交货,和活跃 caspase-3 的增加的表情有关。在结论, K-ras/c-fos 和 Fas/caspase-3 死亡发信号受体小径在老鼠涉及阴囊的细菌房间的导致铅的 apoptosis。 | Shuying Dong Duoping Liang Na An Li Jia Yujuan Shan Chao Chen Kuo Sun Fei Niu Huiyan Li Songbin Fu | 2009 | Acta Biochimica et Biophysica Sinica2009，41，9： | 4 |
| 4 | A highly sensitive bio-barcode immunoassay for multi-residue detection of organophosphate pesticides based on fluorescence antiquenching显示文摘Balancing the risks and benefits of organophosphate pesticides(OPs)on human and environmental health relies partly on their accurate measurement.A highly sensitive fluorescence anti-quenching multi-residue bio-barcode immunoassay was developed to detect OPs(triazophos,parathion,and chlorpyrifos)in apples,turnips,cabbages,and rice.Gold nanoparticles were functionalized with monoclonal antibodies against the tested OPs.DNA oligonucleotides were complementarily hybridized with an RNA fluorescent label for signal amplification.The detection signals were generated by DNA-RNA hybridization and ribonuclease H dissociation of the fluorophore.The resulting fluorescence signal enables multiplexed quantification of triazophos,parathion,and chlorpyrifos residues over the concentration range of 0.01-25,0.01-50,and 0.1-50 ng/mL with limits of detection of 0.014,0.011,and 0.126 ng/mL,respectively.The mean recovery ranged between 80.3% and 110.8% with relative standard deviations of 7.3%-17.6%,which correlate well with results obtained by liquid chromatography-tandem mass spectrometry(LC-MS/MS).The proposed bio-barcode immunoassay is stable,reproducible and reliable,and is able to detect low residual levels of multi-residue OPs in agricultural products. | Lingyuan Xu Xiuyuan Zhang A.M.Abd El-Aty Yuanshang Wang Zhen Cao Huiyan Jia J.-Pablo Salvador Ahmet Hacimuftuoglu Xueyan Cui Yudan Zhang Kun Wang Yongxin She Fen Jin Lufei Zheng Baima Pujia Jing Wang Maojun Jin Bruce D.Hammock | 2022 | Journal of Pharmaceutical Analysis2022，12，4： | 1 |
