| 1 | Generation of haploid embryonic stem cells from Macaca fascicularis monkey parthenotes显示文摘在从经由单性生殖和男性单性生殖的老鼠的胚胎的干细胞(haESCs ) 启用了在修改基因的动物的哺乳动物的房间和代的基因屏蔽的 haploid 的推导的最近的成功。然而, haESCs 是否能从首领被导出,仍然保持未知。这里,我们从 Macaca fascicularis 猴子的单性生殖的胚囊报导 haESCs 的推导。这些房间,作为 PG-haESCs 称为,是 pluripotent 并且能在 vitro 或在 vivo 区分到三胚胎的细菌层的房间。有趣地,一根猴子 PG-haESC 线(MPH1 ) 的 haploidy 与另一个(MPH2 ) 的相比是更稳定的,作为没有排序的激活荧光的房间(FACS ) ,由 haploid 房间的存在出现超过 140 天 haploid 房间的丰富。重要地,转基因的猴子 PG-haESC 线能被 lentivirus- 和 piggyBac 产生调停 transposon 的基因转移。而且,基因屏蔽在猴子 PG-haESCs 是可行的。我们的结果证明 PG-haESCs 能从猴子被产生,提供为在首领的基因分析的一个理想的工具。 | Hui Yang Zhen Liu Yu Ma Cuiqing Zhong Qi Yin Chikai Zhou Linyu Shi Yijun Cai Hanzhi Zhao Hui Wang Fan Tang Yan Wang Chenchen Zhang Xin-yuan Liu Dongmei Lai Ying Jin Qiang Sun Jinsong Li | 2013 | Cell Research2013，23，10： | 22 |
| 2 | Potassium superoxide oxygen generation rate and carbon dioxide absorption rate in coal mine refuge chambers显示文摘The effects of the molding pressure of a KO2 oxygen plate and the initial concentration of CO2 on the oxygen generation rate, the oxygen generation efficiency, and the carbon dioxide absorption rate were studied using a YES-300 hydraulic press to alter the pressure when forming the oxygen plate used in a coal mine refuge chamber. In addition, changes in the initial concentration of CO2 used in the closedbox model were made by adjusting the CO2 supply system, and a CD-7 multi-function parameter instrument was employed to monitor and record the changes of O2 and CO2concentration in the closed-box model. Results indicate that the oxygen generation rate of KO2 oxygen plates, the oxygen generation efficiency, and the carbon dioxide absorption rate decrease when there is an increase in the pressure used to mold the oxygen plates, but those values increase when the initial CO2 concentration increases. When the initial concentration of CO2 in the closed-box model is 3.5% and the forming pressure is 10 k N, the average oxygen generation rate of 15 g KO2 oxygen plate is 11.88 10 3L/min, the oxygen generation efficiency is 80.3%, and the average CO2 absorption rate is 11.0 10 3L/min. Compared with the condition where the initial CO2 concentration is 1.5%, the results show that average oxygen generation rate of oxygen plates increases by 88.9%, the oxygen generation efficiency increases by 88.9%, and the CO2 absorption rate increases by 100%. | Gao Na Jin Longzhe Hu Haohao Huang Xiao Zhou Li Fan Linyu | 2015 | International Journal of Mining Science and Technology2015，25，1： | 4 |
| 3 | High-performance fiber-integrated multifunctional graphene-optoelectronic device with photoelectric detection and optic-phase modulation显示文摘In graphene-based optoelectronic devices,the ultraweak interaction between a light and monolayer graphene leads to low optical absorption and low responsivity for the photodetectors and relative high half-wave voltage for the phase modulator.Here,an integration of the monolayer graphene onto the side-polished optical fiber is demonstrated,which is capable of providing a cost-effective strategy to enhance the light–graphene interaction,allowing us to obtain a highly efficient optical absorption in graphene and achieve multifunctions:photodetection and optical phase modulation.As a photodetector,the device has ultrahigh responsivity(1.5×10^(7) A/W)and high external quantum efficiency(>1.2×10^(9)%).Additionally,the polybutadiene/polymethyl methacrylate(PMMA)film on the graphene can render the device an optical phase modulator through the large thermo-optic effect of the PMMA.As a phase modulator,the device has a relatively low half-wave voltage of 3 V with a 16 dB extinction ratio in Mach–Zehnder interferometer configuration. | LINQING ZHUO PENGPENG FAN SHUANG ZHANG YUANSONG ZHAN YANMEI LINYU ZHANG DONGQUAN LI ZHEN CHE WENGUO ZHU HUADAN ZHENG JIEYUAN TANG JUN ZHANG YONGCHUN ZHONG WENXIAO FANG GUOGUANG LU JIANHUI YU ZHE CHEN | 2020 | Photonics Research2020，8，12： | 3 |

| 6 | Conversion of acetate and glyoxylate to fumarate by a cell-free synthetic enzymatic biosystem显示文摘Fumarate is a value-added chemical that is widely used in food,medicine,material,and agriculture industries.With the rising attention to the demand for fumarate and sustainable development,many novel alternative ways that can replace the traditional petrochemical routes emerged.The in vitro cell-free multi-enzyme catalysis is an effective method to produce high value chemicals.In this study,a multi-enzyme catalytic pathway comprising three enzymes for fumarate production from low-cost substrates acetate and glyoxylate was designed.The acetyl-CoA synthase,malate synthase,and fumarase from Escherichia coli were selected and the coenzyme A achieved recyclable.The enzymatic properties and optimization of reaction system were investigated,reaching a fumarate yield of 0.34 mM with a conversion rate of 34%after 20 h of reaction.We proposed and realized the conversion of acetate and glyoxylate to fumarate in vitro using a cell-free multi-enzyme catalytic system,thus providing an alternative approach for the production of fumarate. | Congli Hou Linyue Tian Guoli Lian Li-Hai Fan Zheng-Jun Li | 2023 | Synthetic and Systems Biotechnology2023，8，2： | 0 |
| 7 | Design of a new type of mine rescue relay cabin显示文摘This paper presents the design of an innovative mine emergency rescue relay cabin, and investigates a detailed comparison of existing shelter facilities, their function, service object, structures, size, and system components with the newly designed mine emergency rescue relay cabin. Air-tightness test indicated a test chamber relief rate of 26 Pa/min, which meets the design requirements. Furthermore,respirator replacement test showed an average time of 73.7 s to replace a respirator. The air cover air supply test indicated an air supply rate of 220 L/min, which is sufficient for the staff replacing the respirator in the emergency rescue relay cabin. The total air supply volume is 9680 L, which can be supplied via two compressed air cylinders of 40 L, pressurized to15 MPa. | Gao Na Chen Ruoyu Shen Jie Jin Longzhe Liu Jianguo Zhang Hao Wang Weixiang Fan Linyu | 2017 | International Journal of Mining Science and Technology2017，27，4： | 0 |
| 8 | 间隙连接蛋白connexin43在膀胱移行细胞癌组织中的表达及其与Bcl-2、Bax表达的相关性(英文)显示文摘Objective: To study the expression of connexin43 (Cx43) gene and its correlation with the apoptosis related genes Bcl-2 and Bax in transitional cell carcinoma of the bladder (BTCC), and to investigate the role of Cx43 in the BTCC. Methods: Reverse transcription polymerase chain reaction was used to detect the expression of Cx43 mRNA and immunocytochemistry technique was used to detect the expressions of Bcl-2 and Bax proteins in 60 cases of BTCC tissues, and compared with that of 15 cases of pericancerous tissues and 15 cases of normal bladder tissues. Results: The positive expression rate of Cx43 mRNA in 60 cases of BTCC tissues was 43.33% which was significantly lower than that in pericancerous tissues (73.33%) and normal tissues (100%) (χ2 = 17.58, P < 0.01). The expression of Cx43 had significant negative correlation with the pathological degree and lymph node metastasis of BTCC (χ2 = 9.33 and 9.74, respectively, P < 0.01). However, no correlation was found between the expression and patient sex, age, clinical staging and diameter and growth pattern of BTCC (P > 0.05). Expression of Cx43 negatively correlated with Bcl-2 protein (r = -0.63, P < 0.01) and positively correlated with Bax protein (r = 0.52, P < 0.01). Conclusion: The down-regulated expression of Cx43 gene was closely associated with the development, invasion and metastasis of BTCC. It could be used as a prognostic indicator for BTCC. Cx43 gene may have antagonistic effects with Bcl-2 gene and synergic with Bax gene in the initiation and progression of BTCC. | Zhengguo Cao Youwen Sun Ling Oi Longchang Fan Jun Xiao Linyu Zhou Yuping Zhu | 2007 | The Chinese-German Journal of Clinical Oncology2007，6，6： | 0 |
