| 2 | Effect of Pb and Cd Stress on the Growth of Potato and Its Antioxidase System显示文摘With the potato variety Xishu 1as the test materials,this paper adopted tissue culture to study the effect of Pb and Cd stress with different mass fractions on potato growth and the antioxidase system.The results showed that under the stress of Pb(200mg/kg)and Cd(20mg/kg),growth of potato had no obvious difference with that in control group;under the stress of Pb(>200mg/kg)and Cd(>20mg/kg),potato growth suspended,and its physiological indexes such as dry weight,plant height,root number,root length were inhibited obviously.With the increasing mass fraction of Pb,relative electrical conductivity,MDA and proline of potato leaves showed the tendency of increase,and the results in high mass fraction treatments showed significant difference with those in the control group(P <0.05),CAT,POD and SOD activity of leaves increased greatly with the increasing mass fraction.In the Pb stress treatment(200mg/kg),relative electrical conductivity,MDA and proline of potato leaves showed no obvious difference with those in the control group,and the results in high mass fraction treatments were significantly higher than those in the control group(P <0.05),CAT and SOD activity increased greatly with the increasing mass fraction(P <0.05).Under the stress of Pb and Cd,synthesis of soluble protein in potato leaves was strongly inhibited.The results showed that potato was tolerant to Pb and Cd of lower mass fraction,and damage of potato caused by Pb and Cd stress could be relieved by improving activity of antioxidase and reducing peroxidation of membrane lipid,and the tolerance reduced with the increase of stress. | Li Peihua Liu Xiaowen Pan Tao Cai Guangzhe | 2015 | Plant Diseases and Pests2015，6，2： | 1 |

| 4 | Corrosion characteristics of single-phase Mg-3Zn alloy thin film for biodegradable electronics显示文摘Biodegradable metals as electrodes, interconnectors, and device conductors are essential components in the emergence of transient electronics, either for passive implants or active electronic devices, especially in the fields of biomedical electronics. Magnesium and its alloys are strong candidates for biodegradable and implantable conducting materials because of their high conductivity and biocompatibility, in addition to their well-understood dissolution behavior. One critical drawback of Mg and its alloys is their considerably high dissolution rates originating from their low anodic potential, which disturbs the compatibility to biomedical applications. Herein, we introduce a single-phase thin film of a Mg-Zn binary alloy formed by sputtering, which enhances the corrosion resistance of the device electrode, and verify its applicability in biodegradable electronics. The formation of a homogeneous solid solution of single-phase Mg-3Zn was confirmed through X-ray diffraction and transmission electron microscopy. In addition, the dissolution behavior and chemistry was also investigated in various biological fluids by considering the effect of different ion species. Micro-tensile tests showed that the Mg-3Zn alloy electrode exhibited an enhanced yield strain and elongation in relation to a pure Mg electrode. Cell viability test revealed the high biocompatibility rate of the Mg-3Zn binary alloy thin film. Finally, the fabrication of a wireless heater demonstrated the integrability of biodegradable electrodes and highlighted the ability to prolong the lifecycle of thermotherapy-relevant electronics by enhancing the dissolution resistance of the Mg alloy. | Ji-Woo Gu Jae-Young Bae Guangzhe Li Hae Won Hwang So-Hyeon Lee Sung-Geun Choi Ju-Young Kim Myoung-Ryul Ok Yu-Chan Kim Seung-Kyun Kang | 2023 | Journal of Magnesium and Alloys2023，11，9： | 0 |
| 5 | Amyloid precursor-like protein 2 C-terminal fragments upregulate S100A9 gene and protein expression in BV2 cells显示文摘The murine microglial cell line BV2 has neuroprotective effects, but is toxic to neurons by secreting inflammatory cytokines, and is an important target in the treatment of nerve inflammation and neurodegenerative diseases. In the present study, we observed the effects of transfecting three amyloid precursor-like protein 2(APLP2) C-terminal fragments(CTFs; C57, C50 and C31) in the p EGFP-N1 vector on S100A9 expression in BV2 cells. Reverse transcription-PCR, western blot assay and immunocytochemistry revealed that S100A9 protein and m RNA expression was greater in BV2 cells after CTF transfection than after mock transfection with an empty vector. Furthermore, transfection of full-length APLP2-751 resulted in low levels of S100A9 protein expression. Our results show that APLP2-CTFs upregulate S100A9 protein and m RNA expression in BV2 cells, and identify a novel pathway involved in neuronal injury and apoptosis, and repair and protection in Alzheimer's disease. | Guangzhe Li Hui Chen Lin Cheng Rongjie Zhao Junchang Zhao Yanji Xu | 2014 | Neural Regeneration Research2014，9，21： | 0 |
| 6 | Computational design of Mg alloys with minimal galvanic corrosion显示文摘Formation of galvanic cells between constituent phases is largely responsible for corrosion in Mg-based alloys.We develop a methodology to calculate the electrochemical potentials of intermetallic compounds and alloys using a simple model based on the Born-Haber cycle.Calculated electrochemical potentials are used to predict and control the formation of galvanic cells and minimize corrosion.We demonstrate the applicability of our model by minimizing galvanic corrosion in Mg-3wt%Sr-x Zn alloy by tailoring the Zn composition.The methodology proposed in this work is applicable for any general alloy system and will facilitate efficient design of corrosion resistant alloys. | Krishnamohan Thekkepat Hyung-Seop Han Ji-Won Choi Seung-Cheol Lee Eul Sik Yoon Guangzhe Li Hyun-Kwang Seok Yu-Chan Kim Jae-Hun Kim Pil-Ryung Cha | 2022 | Journal of Magnesium and Alloys2022，10，7： | 0 |
