| 1 | Fluorescence enhancement and cytotoxicity reduction of bis-viologen biphenyl by complexation of cucurbit[7]uril显示文摘The effect of cucurbit[7]uril(CB[7]) on fluorescence properties and biocompatibility of the bis-viologen biphenyl molecule(BPV22+) was investigated by using 1 H NMR spectroscopy,fluorescence emission titration,and in vitro cytotoxicity experiments.CB[7] can be combined with BPV22+ in a stoichiometric ratio of 1:1 and 2:1.After the formation of host-guest complex,the fluorescence emission intensity of BPV22+ increased significantly,and the emission spectrum blue shifted.Meanwhile,the host-guest complexes showed better biocompatibility than BPV22+ in cell cytotoxicity studies.Results of this paper lay a foundation for the development of host-guest type of fluo rescent probes,biological imaging and so forth. | Jing Zhou Shengzhen Hou Jin Zhang Yanru Chen Hao Chen Yebang Tan | 2021 | Chinese Chemical Letters2021，32，2： | 1 |
| 2 | Estimation of Economic and Ecological Value of Raising Sheep in Pastoral Area显示文摘Tibetan sheep is a unique breed of livestock in Alpine pastoral areas,which is one of the main economic pillars of animal husbandry in pastoral areas,in order to analyze and compare the estimated the economic and ecological benefits of Tibetan sheep under different feeding modes,this paper used a simplified model from multiple angles of animal production,economics and Ecology,The results show that:(i)Under the traditional grazing condition,the annual income of raising one ewe is only 23.4 yuan;(ii)Under the high-efficiency breeding mode,the average income of ewes bred by high-efficiency technology was 168 yuan/(head·year),which was 7 times higher than that of ewes under traditional grazing;each lamb could produce an indirect economic benefit of 500 yuan;(iii)The ecosystem service value affected by each Tibetan sheep through grassland was above 150000 yuan. | Zenghai LUO Shengzhen HOU Zhiyou WANG Yuchun XIN Huakun ZHOU Guiying YUAN | 2020 | Asian Agricultural Research2020，12，6： | 0 |
