| 1 | Effects of Fluoride on Lipid Peroxidation, DNA Damage and Apoptosis in Human Embryo Hepatocytes显示文摘Objective To investigate the effects of fluoride on lipid peroxidation, DNA damage and apoptosis in human embryo hepatocyte L-02 cells. Methods Lipid peroxide (LPO) level, reduced glutathione (GSH) content, DNA damage, apoptosis, and cell cycle analysis were measured after in vitro cultured L-02 cells were exposed to sodium fluoride at different doses (40 μg/mL, 80 μg/mL, and 160 μg/mL) for 24 hours. Results Fluoride caused an increase of LPO levels and a decrease of GSH content in L-02 cells. There appeared to be an obvious dose-effect relationship between the fluoride concentration and the observed changes. Fluoride also caused DNA damage and apoptosis and increased the cell number in S phase of cell cycle in the cells tested. There was a statistically significant difference in DNA damage and apoptosis when comparing the high dose of fluoride treated cells with the low dose of fluoride treated cells. Conclusion Fluoride can cause lipid peroxidation, DNA damage, and apoptosis in the L-02 cell experimental model and there is a significant positive correlation between fluoride concentration and these pathological changes. | AI-GuoWANG TAOXIA QI-LONGCHU MINGZHANG FANGLIU XUE-MINCHEN KE-DIYANG | 2004 | Biomedical and Environmental Sciences2004，17，2： | 18 |

| 5 | In vitro Regeneration of First-generation Inbred Progenies of Cucurbita pepo L. Double Haploids显示文摘Using seeds of inbred progenies of Cucurbita pepo L. DH12-11409 double haploids as experimental materials,the effects of different hormone combinations,explant types and seedling ages on adventitious bud regeneration and rooting of C. pepo L. were investigated. According to the results,inoculating cotyledonary nodes of yellow-green cotyledons from 5-d-old C. pepo L. double haploids to MS + 30 g / L Suc + 8 g / L Agar + 2. 0 mg / L 6-BA + 0. 1 mg / L NAA led to the best results with the induction frequency of 90. 0% and differentiation coefficient of 8. 5. MS medium with addition of 0. 05 or 0. 1 mg / L NAA led to the highest rooting rate. Regenerated seedlings with 5- 6 true leaves exhibited the highest survival rate of 90. 0%,which was the optimal period for domestication and transplanting of regenerated seedlings. This study laid a solid foundation for high-efficiency utilization of heterosis of C. pepo L. | Yongan CHENG Enhui ZHANG Xiaofei ZHAO Taoxia TANG Zhongmin XU | 2015 | Agricultural Biotechnology2015，4，4： | 1 |
| 6 | In-situ anion exchange based Bi_(2)S_(3)/OV-Bi_(2)MoO_(6)heterostructure for efficient ammonia production:A synchronized approach to strengthen NRR and OER reactions显示文摘Photocatalytic ammonia generation via nitrogen reduction reaction(NRR)is a green and prospective nitrogen fixation technique.However,NRR is often hampered by the high N_(2) adsorption/activation energies and is accompanied by a slow kinetics oxygen evolution reaction(OER).Herein,a robust Bi_(2)S_(3)/OVBi_(2)MoO_(6)S-scheme heterojunction is constructed using a simple in-situ anion exchange process,which enables oxygen vacancy(OVs)abundant Bi_(2)Mo O_(6) microspheres with surface deposited Bi_(2)S_(3).The asfabricated Bi_(2)S_(3)/OVBi_(2)MoO_(6) functioned as an effective photocatalyst to convert N_(2)-to-NH_(3) under mild conditions.The photocatalytic NH_(3)/NH_(4)^(+) production rate reached 126μmol g_(cat)^(-1)under visible light for2.5 h with 2%of Bi_(2)S_(3)/OVBi_(2)MoO_(6)photocatalyst,which was 8-fold higher than pristine Bi_(2)MoO_(6).Furthermore,the as-fabricated Bi_(2)S_(3)/Bi_(2)MoO_(6)heterojunction exhibited good selectivity,high stability and reproducibility.The excellent photocatalytic NRR performance was ascribed to the Bi_(2)S_(3)/Bi_(2)MoO_(6)heterojunction formed subsequent to the strong interaction between Bi_(2)S_(3)and Bi_(2)MoO_(6).The OVs facilitated the chemical adsorption process allowing activation of N_(2)molecule on the Bi_(2)S_(3)/Bi_(2)MoO_(6).Simultaneously,the S-scheme heterojunction prolonged the lifetime of photogenerated carriers,accelerated the electrons/holes spatial separation and accumulation on the Bi_(2)S_(3)(reduction)and Bi_(2)MoO_(6)side(oxidation),respectively,thus strengthening both OER and NRR half-reactions.This simple in-situ anion exchange method offers a novel technique for strengthening OER and NRR half-reactions in Bi-based photocatalysts for effective photocatalytic ammonia generation. | Yuanyuan Zhang Li Guo Yingxian Wang Tianyu Wang Taoxia Ma Zhuangzhuang Zhang Danjun Wang Bin Xu Feng Fu | 2022 | Journal of Materials Science & Technology2022，，15： | 0 |
