| 1 | Flexibility in the order of action and in the enzymology of the nuclease, polymerases, and ligase of vertebrate non-homologous DNA end joining: relevance to cancer, aging, and the immune system显示文摘加入的 Nonhomologous 脱氧核糖核酸结束(NHEJ ) 是为在人的房间并且在多细胞的优核质的双海滨脱氧核糖核酸裂缝的修理的主要小径。双海滨裂缝的原因经常碎裂在损坏的地点的脱氧核糖核酸,导致在那里的信息的损失。NHEJ 不恢复失去的信息并且可以将切除另外的核苷酸在修理过程期间。修理大量 overhang 并且损坏配置的能力反映 NHEJ 的核酸酶,聚合酶,和连接酶的灵活性。单个部件的灵活性也解释 NHEJ 能在修理脱氧核糖核酸结束的任何给定的对的方法的大数字。局部地,在 NHEJ 的地点,修理可以贡献癌症和老化的信息的损失,而是由 NHEJ 的行动保证染色体的全部片断没被失去。 | Michael R Lieber Haihui Lu Jiafeng Gu Klaus Schwarz | 2008 | Cell Research2008，18，1： | 5 |
| 2 | Recent progress of two-dimensional nanosheet membranes and composite membranes for separation applications显示文摘Two-dimensional(2D)materials have emerged as a class of promising materials to prepare high-performance 2D membranes for various separation applications.The precise control of the interlayer nano-channel/sub-nanochannel between nanosheets or the pore size of nanosheets within 2D membranes enables 2D membranes to achieve promising molecular sieving performance.To date,many 2D membranes with high permeability and high selectivity have been reported,exhibiting high separation performance.This review presents the development,progress,and recent breakthrough of different types of 2D membranes,including membranes based on porous and non-porous 2D nanosheets for various separations.Separation mechanism of 2D membranes and their fabrication methods are also reviewed.Last but not the least,challenges and future directions of 2D membranes for wide utilization are discussed in brief. | Wei Wang Yanying Wei Jiang Fan Jiahao Cai Zong Lu Li Ding Haihui Wang | 2021 | Frontiers of Chemical Science and Engineering2021，15，4： | 2 |
| 3 | Dual inhibition of glycolysis and oxidative phosphorylation by aptamer-based artificial enzyme for synergistic cancer therapy显示文摘Dual inhibition of glycolysis and oxidative phosphorylation(OXPHOS)can break the metabolic plasticity of cancer cells to inhibit most energy supply and lead to effective cancer therapy.However,the pharmacokinetic difference among drugs hinders these two inhibitions to realize a uniform temporal and spatial distribution.Herein,we report an aptamer-based artificial enzyme for simultaneous dual inhibition of glycolysis and OXPHOS,which is constructed by arginine aptamer modified carbon-dots-doped graphitic carbon nitride(AptCCN).AptCCN can circularly capture intracellular arginine attribute to the specific binding ability of arginine aptamers to arginine,and further catalyze the oxidation of enriched arginine to nitric oxide(NO)under red light irradiation.In vitro and in vivo experiments showed that arginine depletion and NO stress could inhibit glycolysis and OXPHOS,leading to energy blockage and apoptosis of cancer cells.The presented aptamer-based artificial enzyme strategy provides a new path for cell pathway regulation and synergistic cancer therapy. | Xiao Fang Meng Yuan Junduan Dai Qianying Lin Yuhong Lin Wenli Wang Yifan Jiang Haihui Wang Fang Zhao Junye Wu Shumeng Bai Chunhua Lu Huanghao Yang | 2022 | Nano Research2022，15，7： | 0 |
| 4 | Introduction and Influence of Water in the Preparation of Crosslinked PVC Foam by Isocyanate显示文摘In the preparation process of crosslinked polyvinyl chloride(c-PVC)foam by isocyanate,the formulated mixture is generally required to be carried out under the condition of isolated water,so as to avoid the mixing difficulties caused by the reaction between the introduced water and isocyanate.In this paper,NaHCO_(3) was added to the mixture to indirectly introduce water into the system,and the effects of NaHCO_(3) on the cell structure and curing time of c-PVC foam were investigated.The results showed that NaHCO_(3) not only played a role of foaming agent,but also was a good nucleating agent for cells.At the same time,the introduction of NaHCO_(3) held back the exudation of modified diphenylmethane-4,4'-diisocyanate(MDI)on the cell wall.The effects of NaHCO_(3) on the cell structure and aggregation structure of c-PVC foam were studied by thermogravimetric analysis,infrared spectroscopy and scanning electron microscopy.The results showed that decomposition of NaHCO_(3) occurred during the molding stage,which made small amount of MDI react with water to form polyurea,improved the compatibility of MDI with PVC and inhibited the exudation of MDI. | BI Xiang LI Minggang LU Min YOU Jiangan XUE Jian YU Haihui JIANG Zhiwei TANG Tao | 2023 | Chemical Research in Chinese Universities2023，39，5： | 0 |
| 5 | Two-dimensional Cu-porphyrin nanosheet membranes for nanofiltration显示文摘A kind of two-dimensional(2D)metal-organic framework(MOF)material,Cu-meso-tetrakis(4-carboxyphenyl)porphine(Cu-TCPP)nanosheets with wrinkled and flat morphologies are used as building blocks to assemble membranes by vacuum filtration(VF)and electrophoretic deposition(EPD)as energy-efficient nanofiltration(NF)membranes to remove dyes from water.Since the nanosheets with wrinkled structure can provide additional water transport channels,thereby increasing the water permeance,in the premise of a high rejection(>97.0%)for the dye brilliant blue G(BBG)(1.60 nm×1.90 nm),the water permeance of the membrane assembled by the wrinkled nanosheets(~1170 nm)is about 4 times that of the membrane assembled by the flat nanosheets(~530 nm),reaching 16.39 L·m^(−2)·h^(−1)·bar^(−1).Additionally,the use of the relatively flat nanosheets and the membrane preparation method of electrophoretic deposition is more conducive to stack nanosheets orderly and reduce defects.Therefore,the water permeance of the membrane prepared by EPD(~1170 nm)with flat nanosheets is about twice that of the membrane prepared by VF(~530 nm),achieving 9.40 L·m^(−2)·h^(−1)·bar^(−1)with similar rejection(>97.0%)of dye evans blue(EB)(3.10 nm×1.20 nm).Furthermore,these membranes still exhibit good separation performance at high pressure of 0.6 MPa.Nanosheets with diverse structures and various membrane fabrication processes provide new directions for the separation performance optimization of 2D MOF materials for water purification. | Jiahao Cai Shizheng Song Lijie Zhu Qipeng Lu Zong Lu Yanying Wei Haihui Wang | 2023 | Nano Research2023，16，5： | 0 |
