| 1 | Characterization of wet microalgal cells pretreated with steam for lipid extraction显示文摘Steam pretreatment was employed to disrupt Microalgal cells for lipids extraction.Effects of steam pretreatment on microstructure of microalgal cells were investigated through scanning electron microscopy(SEM)and transmission electron microscopy(TEM).Effect of treatment on lipid extraction was also studied.Microalgal cell walls were distorted after steam pretreatment due to the hydrolysis of organic macromolecules contained in cell wall.Maximum curvature was increased from 1.88×10^(-6) m^(-1) to 1.43×10^(-7) m^(-1) after treatment with the steam at 130℃.The fractal dimension of microalgal cells increased from 1.25 to 1.30 after pretreatment for 15 min,and further increased to 1.47 when the pretreatment time was increased to 60 min.Increased steam pretreatment temperature and time enhanced the hydrolysis of organic macromolecules,and finally destroyed microalgal cell walls at pretreatment temperature of 130℃and pretreatment time of 60 min.Lipid extracted from wet microalgal was significantly increased(2.1-fold)after pretreatment. | Wenlu Song Rui Huang Hao Guo Chunguang Yin Chuanling Wang Jun Cheng Weijuan Yang | 2021 | Chinese Journal of Chemical Engineering2021，34，9： | 0 |
| 2 | WORLD TRENDS 1993显示文摘Drastic, profound changes visited upon the world in 1992, featuring complicatedunpredicabilities. New changes, new problems and therefore, new features,are bound to crop up in the unfolding 1993. Yet, however spectacular they may be,the evolving post-Cold War world power configuration will more or less come | Li Zhongcheng Guo Chuanling* ·Li Zhongcheng Guo Chuanling, both Research Fellows, China Institute of Contemporary International Relations. | 1993 | Contemporary International Relations1993，3，1： | 0 |
| 3 | Radiosensitivity of Hepatoma Cell Lines and Human Normal Liver Cell Lines Exposed to ^(12)C^(6+) Ions显示文摘Cancer is the one of the most terrible disease to human. Intrinsic radiosensitivity of cells is one of the most important factor in influencing the success or failure of the radiotherapy, especially between normal organs and malignancy. To predict the radiosensativity is a major part of the therapy project. There are many methods that can be used to assess the radiosensitivity, colony assay is one of the most classical methods on predicting the radiosensiticity of tumor cells. But some shortage could not | Jing Xigang, Li Wenjian, Yang Jianshe, Guo Chuanling and Dang Bingrong | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
| 4 | G_2 Chromosome Radiosensitivity in Human Tumor Cells after γ-rays Irradiation显示文摘It is well established that the radio-sensitivity is dependent of cell cycle progression, and among the each stage of interphase, G2 phase is the most radiosensitive, G1 phase is the second radiosensitive, S phase is the last radiosensitive, while Go phase is radio-resistent for absent oxygen and enough repairing time. Previous studies led to the conclusion that G2 phase is a very important stage. There are two techniques to study the chromosome aberrations in G2-cells, namely, G2-assay and G2-PCC technique. The G2-assay is to analyze the subsequent metaphases after irradiation, and with which studies indicate that | Wang Zhuanzi,Li Wenjian,Yang Jianshe, Jin Xiaodong Xia Jingguang, Wang Jufang and Guo Chuanling | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
| 5 | Effects of Heavy Ion Irradiation on Cell Survival and Cell Cycle Delays in Synchronous SMMC-7721 Hepatoma Cells显示文摘Ionizing radiation produces various kinds of damage, for example, DNA double- or single-strand break, and base damage. Cellular responses after ionizing radiation exposure can be considered to protect the cells from the radiation-induced damage. The purpose of this study is to investigate and compare cell survival and cell cycle progression in human hepatoma cells (SMMC-7721) synchronized at G0/C1,G1/S and G2/M phases, respectively. | Wei Wei, Li Wenjian, Xia Jinguang, Jin Xiaodong, Guo Chuanling, Li Qiang and Su Xu | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
| 6 | Effects of 80 MeV/u ^(12)C^(6+) Ion Radiation Mouse Head on Immunity Cell Cycle Distributions显示文摘After whole head irradiation (WHI) of mice with heavy ions, we study the changes of cycle distribution of bone marrow, spleen and peripheral lymphocyte cells, and the aim is to provide basic data for space radiation protection and biological object oriented ion therapy. The heads of the BALB/c mice were irradiated with 0, 0. 5, 1,2, 4 or 10 Gy by 12C6+ ions (80 MeV/u, 1 Gy/min) and then the cell cycle distribu- | Bing Tao, Dang Bingrong, Xie Yi, Li Wenjian,Ma Qiufeng, Wang Jufang, Qiu Rong Zhou Libin, Guo Chuanling,Jing Xigang, Zhang Hong, Li Qiang Yuan Zhigang and Ma Shuang | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
| 7 | Hyper-radiosensitivity Effect of Human Hepatoma SMMC-7721 Cell Exposed to Low Dose γ Ray and ^(12)C Ion显示文摘Hypersensitive response of mammalian cells in cell killing to X andγrays has been reported at doses below 1 Gy. The purpose of this study was to examine the low-dose sensitivity of human hepatoma SMMC-7721 cells irradiated with 60Coγrays and 50 MeV/u 12C ions. Experiments-of usingγrays and charged particle irradiation were performed, particularly in the low-dose range from 0 to 2 Gy.

| 8 | Theoretical Exploration on Ultra-fractionated Radiotherapy显示文摘Based on the HRS effect, a new tumour radiotherapy method, ultra-fractionation has been devised. Compared with conventional fractionation, the dose per fraction is decreased from 2 to 0. 2-0. 5 Gy for the ultra-fractionation. Although the amount of fractions are increased in order to reach the same therapeutic efficacy, the total dose is significantly reduced. | Jin Xiaodong, Li Qiang,Guo Chuanling, Wang Jufang, Hao Jinfang Li Wenjian,Yan Zheng and Dai Zhongying | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |

| 10 | Research of Effect of ^(60)Co γ-ray Irradiation on Cell Cycle of SMMC-7721 Tumor Cell with Flow Cytometery显示文摘The resultsMost researchof cell cycle play an important role in resear, ching tumor occurrence, development and treatment. results show that malignant grade and pharmic sensitivity of tumor are relative to cell cycle. The sensitivity of medications is different to different phases of cell cycle of tumor. In general, the cell of M are more sensitivity. On the side, different medications have different action in different cell cycle. The irradiation can change cell cycle proccss and can induce the pattern of changes in cell cycle. For cxamplc, G1 arrest, G2 arrest and S arrest. So, thc research rcsults of tumor cell cycle in different irradiation have not only biological means but also realistic means for selecting chemical therapy medication after radiotherapy. | Dang Bingrong, Ma Qiufeng, Gao Qingxiang, Li Wenjian, Hao Jifang, Xie Yi and Guo Chuanling | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |
| 11 | Effects of Nitric Oxide on Growth and Sensitivity of Human Glioma A172 Cells to ^(60)Co and X-ray Radiation显示文摘Nitric oxide (NO)has been implicated both in regression and progression of tumors due to its production by both tumor cells and infiltrating lymphocytes. Ionizing radiation causes the regression of tumors, and can augment the production of NO by macrophages in vitro. The authors examined the effect of nitric oxide (NO) generating agent sodium nitroprusside (SNP) on the growth and radiosensitivity of cultured glioma A172 cells to ^60Co or X-ray radiation. | Qiu Rong, Liu Bing, Guo Chuanling, Li Wenjian, Ma Qiufeng and Li Sha | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |
