| 1 | Anti-tumor activity and immunological modification of ribosome-inactivating protein (RIP) from Momordica charantia by covalent attachment of polyethylene glycol显示文摘使核糖体失去活性的蛋白质(裂开) 是酶的一个家庭那 depurinate rRNA 并且禁止蛋白质生合成。这里,我们报导纯化,导致 apoptosis 活动,和聚乙烯乙二醇(木钉) 修正从痛苦的甜瓜种子裂开。蛋白质有 N-Asp-Val-Ser-Phe-Arg 的一个同质的 N 终端序列。而且, RIP 显示了强壮的导致 apoptosis 活动和压制的癌症细胞生长。这可能被归因于 caspases-3 的激活。使它可得到为在 vivo 申请, immunogenicity 裂开被化学修正与 20 kDa (mPEG ) 减少 2-Lys-NHS。PEGylated 和 non-PEGylated 的抑制活动对癌症房间裂开比对正常 PEGylated 的房间,和 antigenicity 裂开的强壮得多显著地被减少。我们的结果建议 PEGylated 裂开可能潜在地作为反癌症被开发药。 | Mengen Li Yiwen Chen Zhongyu Liu Fubing Shen Xiaoxiao Bian Yanfa Meng | 2009 | Acta Biochimica et Biophysica Sinica2009，41，9： | 11 |

| 3 | Resistless photochemical etching of a silicon wafer by UV laser with an H_2O_2 and HF aqueous solution显示文摘A new resistless etching method has been de-veloped for Silicon wafers. This new method uses an aqueous solution consisting of hydrogen peroxide (H2O2) and hydro-gen fluoride (HF) as the activating etchants. A 193 nm ArF excimer laser and a 266 nm fourth harmonic generation Nd:YAG laser were used as the photon sources. Results showed that pattern etching has been achieved without any photoresist film. In the case of the 193 nm laser, the optimal etching appeared at a 1.3 H2O2/HF ratio, where an etchdepth of 210 nm was achieved with a fluence of 29 mJ/cm2 and shot number of 10000. At the same conditions, the etch depth with H2O2 and HF solution was three times of that by using H2O and HF mixture. In the case of the 266 nm Nd : YAG laser, the optimal etching appeared at twice ratio of H2O2/HF, where the etch depth of 420 nm was achieved witha fluence of 12 mJ/cm2 and shot number of 30000. Results showed that the etch effect of the 266 nm Nd : YAG laser was more desirable than that of the 193 nm ArF | YANG Jie, LIU Yanfa & M.

| 4 | Biodiversity Risk and Opportunity Assessment in BAT Cooperative Tobacco-growing Areas显示文摘Using the method in Biodiversity Risk and Opportunity Assessment Handbook of British American Tobacco Biodiversity Partnership,we assess biodiversity risks and opportunities in BAT and China's cooperative tobacco-growing areas. The assessment results indicate that there are 8 risks and 1 opportunity. Action and monitoring plans have been made for medium and high risks as well as opportunity,to reduce impact on biodiversity. | Long XU Jingming WANG Kun FENG Yanfa CAI Bin LI Honghui YIN Dafei LI Lianchuan ZHOU Ying MA Gang WANG Pengcheng LIU Runtao LI Changhua ZHOU Ke YANG Jian CHEN | 2016 | Asian Agricultural Research2016，8，2： | 0 |
