| 1 | Enrichment of heavy metals in coal gangue by puff balls and mechanism research显示文摘Coal gangue with/without wild puff balls growing on or covering up were analyzed by means of inductively coupled plasma atomic emission spectrometry(ICP-AES) and atomic fluorescence spectrometry(AFS) to detect the contents of heavy metal elements in the plants. Seven heavy metals were chosen to do the experiments, which showed that the puff balls have strong enrichment capacity for heavy metals(As, Pb, Mn and Ni). The highest enrichment level was Mn, 220.3 mg/kg(dry weight) for puffball fruiting bodies, and the highest As, Cr and Pb enrichment levels for puffball mycelium were 111, 265.3 and 86 mg/kg, respectively. Cd, Mn and Ni could transfer from puffball mycelium to its fruiting bodies, while As, Cr, Pb and Co mainly accumulated in the mycelium. The contents of five organic acids(tartaric acid, glycolic acid, lactic acid, citric acid and malic acid) in puffballs were determined with high performance liquid chromatography. With water, ethanol and ethyl acetate as solvents, the puffball extracts performed dissolution reactions with coal gangue, in which the water extract(containing a large amount of organic acids) was most effective in releasing heavy metals, especially As, Pb, Cr, Mn, Co and Ni from coal gangue. As a pioneer species, puff balls absorbed the hazardous trace elements in coal gangue matrix to reduce its eco-toxicity, on the other hand, it raised the p H value of coal gangue, improving the vegetation growing conditions for coal gangue matrix to a certain extent and laying the foundation for ecological restoration of coal gangue dumps. | CHEN Miao ZHU Lijun WU Yonggui FU Tianling RAN Yan | 2014 | Chinese Journal Of Geochemistry2014,33,4: | 4 |
| 2 | Influence of litter decomposition on iron and manganese in the sediments of wetlands for acid mine drainage treatments显示文摘Plant litter will influence the bioavailability of heavy metals in sediments of wetlands used to treat acid mine drainage. To investigate the effect of plant litter on sediments in wetlands and define the comprehensive and continuous role of plant litter, different mass ratios(0%,5%, 20%) of litter were added into the sediments to study the influence of litter decomposition on the overlying water and sediments. The changes in pH, EC, Eh, Fe, and Mn of the overlying water and the organic matter in the sediments and the forms of Fe and Mn after 1, 7, 14, 21, and 28 days of litter decomposition were studied. The results indicated that litter decomposition increased the pH, EC, and reduced Eh of the overlying water. Litter decomposition promoted the release of Fe and Mn from the sediments into the overlying water and with the continuous decomposition of litter, the concentration of Fe and Mn in the overlying water declined. Litter decomposition increased the content of the organic matter in the sediment, and the forms of Fe and Mn indicated that litter decomposition could significantly affect the transformation of the forms of Fe and Mn.Reducible Fe was the main form in the sediments. Litter decomposition promoted the transformation of reducible Fe, the main form found in the sediments, intoexchangeable and oxidizable Fe, but had no effect on residual form. Exchangeable Mn was the main form in the sediments, and litter decomposition accelerated the transformation of reducible Mn, most commonly found in the sediments, into oxidizable Mn and had little influence on the exchangeable and residual forms. | Xiuyue Xu Yonggui Wu Yiling Rao Tianling Fu Xingyu Wu | 2019 | Acta Geochimica2019,38,1: | 1 |

| 4 | Effects of a proline solution cover on the geochemical and mineralogical characteristics of high-sulfur coal gangue显示文摘Batch experiments were conducted to comparatively evaluate the inhibition effects and mechanisms of a low-concentration(1%) proline solution cover on the release of pollutants from high-sulfur coal gangue. Highsulfur coal gangue was continuously immersed in a proline solution and in deionized water(as a control treatment) for540 days. The results showed that the coal gangue in the control treatment was oxidized and generated leachate with poor water qualities, i.e., the leachate exhibited lower p H values, higher redox potential values, higher pollutant concentrations(SO_4^(2-), Fe, Mn, Cu, and Zn), and high levels of acidophilic sulfur-oxidizing bacteria. However,compared to the control treatment, the addition of the proline solution(1%) significantly improved the water quality of the leachate by significantly reducing the Eh values, the pollutant concentrations(SO_4^(2-), Fe^(2+), Fe, Mn,Cu, and Zn), and the activity of acidophilic sulfur-oxidizing bacteria and by significantly increasing the pH value to neutral. The proline treatment significantly inhibited the oxidation of coal gangue and the release of pollutants,mainly by inhibiting the activity of acidophilic sulfur-oxidizing bacteria and by altering the heavy metal fractions and the mineralogical characteristics. Therefore, in engineering practice, workers should consider using an environmental friendly aqueous proline solution cover toachieve the in-situ control of pollutant releases from coal gangue dumps. | Youfa Luo Yonggui Wu Tianling Fu Hu Wang Rongrong Xing Zhilin Zheng | 2018 | Acta Geochimica2018,37,5: | 1 |
| 5 | Desymmetrization of Cyclic 1,3-Diketones under N-Heterocyclic Carbene Organocatalysis:Access to Organofluorines with Multiple Stereogenic Centers显示文摘Symmetric 1,3-diketones with fluorine or fluorinated substituents on the prochiral carbon remain to be established.Herein,we have developed a novel prochiral fluorinated oxindanyl 1,3-diketone and successfully applied these substrates in carbene-catalyzed asymmetric desymmetrization.Accordingly,a versatile strategy for asymmetric generation of organofluorines with fluorine or fluorinated methyl groups has been developed.Multiple stereogenic centers were selectively constructed with satisfactory outcomes.Structurally diverse enantioenriched organofluorines were generated with excellent results in terms of yields,diastereoselectivities,and enantioselectivities.Notably,exchanging fluorinated methyl groups to fluorine for this prochiral 1,3-diketones leads to switchable stereoselectivity.Mechanistic aspects and origin of stereoselectivity were studied by DFT calculations.Notably,some of the prepared organofluorines demonstrated competitive antibacterial activities. | Guanjie Wang Min Zhang Yezhi Guan Ye Zhang Xianfang Hong Chenlong Wei Pengcheng Zheng Donghui Wei Zhenqian Fu Yonggui Robin Chi Wei Huang | 2021 | Research2021,,1: | 0 |

| 7 | U1 snRNP proteins promote proximal alternative polyadenylation sites by directly interacting with 3'end processing core factors显示文摘In eukaryotic cells,both alternative splicing and alternative polyadenylation(APA)play essential roles in the gene regulation network.U1 small ribonucleoprotein particle(U1 snRNP)is a major component of spliceosome,and U1 snRNP complex can suppress proximal APA sites through crosstalking with 3end processing factors.However,here we show that both knockdown and overexpression of SNRPA,SNRPC,SNRNP70,and SNRPD2,the U1 snRNP proteins,promote the usage of proximal APA sites at the transcriptome level.SNRNP70 can drive the phase transition of PABPN1 from droplet to aggregate,which may reduce the repressive effects of PABPN1 on the proximal APA sites.Additionally,SNRNP70 can also promote the proximal APA sites by recruiting CPSF6,suggesting that the function of CPSF6 on APA is related with other RNA-binding proteins and cell context-dependent.Consequently,these results reveal that,on the contrary to U1 snRNP complex,the free proteins of U1 snRNP complex can promote proximal APA sites through the interaction with 3end processing machinery. | Zhijie Hu Mengxia Li Zhanfeng Huo Liutao Chen Susu Liu Ke Deng Xin Lu Shangwu Chen Yonggui Fu Anlong Xu | 2022 | Journal of Molecular Cell Biology2022,14,8: | 0 |
