1Spatial patterns of ecosystem vulnerability changes during 2001–2011 in the three-river source region of the Qinghai-Tibetan Plateau, China显示文摘The three-river source region(TRSR, including Yangtze, Yellow and Lancang rivers), located in the Qinghai-Tibetan Plateau, China, is a typical alpine zone with apparent ecosystem vulnerability and sensitivity. In this paper, we introduced many interdisciplinary factors, such as landscape pattern indices(Shannon diversity index and Shannon evenness index) and extreme climate factors(number of extreme high temperature days, number of extreme low temperature days, and number of extreme precipitation days), to establish a new model for evaluating the spatial patterns of ecosystem vulnerability changes in the TRSR. The change intensity(CI) of ecosystem vulnerability was also analyzed. The results showed that the established evaluation model was effective and the ecosystem vulnerability in the whole study area was intensive. During the study period of 2001–2011, there was a slight degradation in the eco-environmental quality. The Yellow River source region had the best eco-environmental quality, while the Yangtze River source region had the worst one. In addition, the zones dominated by deserts were the most severely deteriorated areas and the eco-environmental quality of the zones occupied by evergreen coniferous forests showed a better change. Furthermore, the larger the change rates of the climate factors(accumulative temperature of ≥10°C and annual average precipitation) are, the more intensive the CI of ecosystem vulnerability is. This study would provide a scientific basis for the eco-environmental protection and restoration in the TRSR.GUO Bing ZHOU Yi ZHU Jinfeng LIU Wenliang WANG Futao WANG Litao YAN Fuli WANG Feng YANG Guang LUO Wei JIANG Lin 2016Journal of Arid Land2016,8,1:16
2RNA-binding protein QKI regulates contact inhibition via Yes-associate protein in ccRCC显示文摘Contact inhibition adjusts organ size to the proper size and ensures the cultured cells growing to a monolayer.By regulating the downstream coordinator YAP,the evolutionarily conserved Hippo transduction pathway attunes cell growth and death in response to cell contact inhibition,polarity,self-renewal,and differentiation.Dysregulation of this pathway is involved in various diseases such as cancer.RNA-binding protein QKI regulates cell proliferation,metabolism,division,and immunity in various cancer models,but its role in cancer cell contact inhibition remains unclear.In this study,we aimed to clarify the relationship between QKI and YAP,and the role of their interaction in cell contact inhibition.We found a lower QKI expression level in sparse condition,whereas a higher expression level in confluent condition by western blot analysis and immunofluorescence assay.QKI knockdown elevated cell proliferation and invasion both in vitro and in vivo.Strikingly,the results of CCK-8 assay,colony formation assay,and transwell assay showed that the phenomenon was in accord with the expression level of pYAP and reverse with YAP.Higher levels of Wnt3a and β-catenin were also found in xenografts of QKI-knockdown clear cell renal cell carcinoma (ccRCC) CAKI-1 cells by western blot analysis and immumohistochemical staining.Finally,a positive correlation between QKI and pYAP was found in clinical specimens by immunohistochemistry.Thus,as a negative regulator of YAP,QKI attuned the cell contact inhibition,leading to inhibition of cancer cell proliferation and invasion through Wnt and GPCR pathway.Zheng Zhu Di Wei Xi'an Li Fuli Wang Fei Yan Zibao Xing Zhao Yan Huanyu Lu Dongsheng Zhai Ziehen Ye Geng Zhang Ping Meng Yu Zheng Jiarui Yuan Zifan Lu Jianlin Yuan 2019Acta Biochimica et Biophysica Sinica2019,51,1:2

6Mechanistic investigation on Ag-Cu_(2)O in electrocatalytic CO_(2) to CH_(4) by in situ/operando spectroscopic and theoretical analysis显示文摘Silver-copper electrocatalysts have demonstrated effectively catalytic performance in electroreduction CO_(2) toward CH_(4),yet a revealing insight into the reaction pathway and mechanism has remained elusive.Herein,we construct chemically bonded Ag-Cu_(2)O boundaries,in which the complete reduction of Cu_(2)O to Cu has been strongly impeded owing to the presence of surface Ag shell.The interfacial confinement effect helps to maintain Cu^(+)sites at the Ag-Cu_(2)O boundaries.Using in situ/operando spectroscopy and theoretical simulations,it is revealed that CO_(2) is enriched at the Ag-Cu_(2)O boundaries due to the enhanced physisorption and chemisorption to CO_(2),activating CO_(2) to form the stable intermediate^(*)CO.The boundaries between Ag shell and the Cu_(2)O mediate local^(*)CO coverage and promote^(*)CHO intermediate formation,consequently facilitating CO_(2)-to-CH_(4) conversion.This work not only reveals the structure-activity relationships but also offers insights into the reaction mechanism on Ag-Cu catalysts for efficient electrocatalytic CO_(2) reduction.Min Sun Luxiao Zhang Fuli Tian Jiaxin Li Yanqiu Lei Heng Zhang Lifeng Han Zhihua Guo Yonghui Gao Fenrong Liu Yan Wang Luhui Wang Shanghong Zeng 2024Journal of Energy Chemistry2024,88,1:0
7A Review on Reasons of Increasing Perennial Weeds and Control Technology of Perennial Weeds in Heilongjiang Province显示文摘The main reasons that perennial weeds has becoming the dominant weeds in Heilongjiang Province were summarized. The biological mechanism that explained why it was difficult to control perennial weeds was analyzed. During dormancy course, variation regularity of some inner matters in perennial weeds was researched and new tentative for controlling the perennial weeds was pointed out.ZHAO Changshan HE Fuli SHI Na YAN Chunxiu 2009Journal of Northeast Agricultural University(English Edition)2009,16,1:0
