| 1 | Feasibility of bioleaching combined with Fenton oxidation to improve sewage sludge dewaterability显示文摘A novel joint method of bioleaching with Fenton oxidation was applied to condition sewage sludge. The specific resistance to filtration(SRF) and moisture of sludge cake(MSC) were adopted to evaluate the improvement of sludge dewaterability. After 2-day bioleaching, the sludge p H dropped to about 2.5 which satisfied the acidic condition for Fenton oxidation.Meanwhile, the SRF declined from 6.45 × 1010 to 2.07 × 1010s2/g, and MSC decreased from91.42% to 87.66%. The bioleached sludge was further conditioned with Fenton oxidation. From an economical point of view, the optimal dosages of H2O2 and Fe2+were 0.12 and 0.036 mol/L,respectively, and the optimal reaction time was 60 min. Under optimal conditions, SRF,volatile solids reduction, and MSC were 3.43 × 108s2/g, 36.93%, and 79.58%, respectively. The stability and settleability of sewage sludge were both improved significantly. Besides,the results indicated that bioleaching-Fenton oxidation was more efficient in dewatering the sewage sludge than traditional Fenton oxidation. The sludge conditioning mechanisms by bioleaching-Fenton oxidation might mainly include the flocculation effects and the releases of extracellular polymeric substances–bound water and intercellular water. | Changgeng Liu Panyue Zhang Chenghua Zeng Guangming Zeng Guoyin Xu Yi Huang | 2015 | Journal of Environmental Sciences2015，27，2： | 12 |
| 2 | Plasma soluble C-type lectin-like receptor-2 is associated with the risk of coronary artery disease显示文摘Accumulating evidence suggests that C-type lectin-like receptor-2(CLEC-2)plays an important role in atherothrombosis.In this case-control study,we investigated the association between CLEC-2 and incidence of coronary artery disease(CAD).A total of 216 patients,including 14 cases of stable angina pectoris(SAP,non-ACS)and 202 cases of acute coronary syndrome(ACS),and 89 non-CAD control subjects were enrolled.Plasma levels of soluble CLEC-2(sCLEC-2)were measured using the enzyme-linked immunosorbent assay(ELISA).Compared with the control group(65.69(55.36–143.22)pg/mL),the plasma levels of sCLEC-2 were significantly increased in patients with CAD(133.67(88.76–220.09)pg/mL)and ACS(134.16(88.88–225.81)pg/mL).The multivariate adjusted odds ratios(95%confidence interval)of CAD reached 2.01(1.52–2.66)(Ptrend<0.001)for each 1-quartile increase in sCLEC-2.Restricted cubic splines showed a positive dose-response association between sCLEC2 and CAD incidence(Plinearity<0.001).The addition of sCLEC-2 to conventional risk factors improved the C statistic(0.821 vs.0.761,P=0.004)and reclassification ability(net reclassification improvement:57.45%,P<0.001;integrated discrimination improvement:8.27%,P<0.001)for CAD.In conclusion,high plasma sCLEC-2 is independently associated with CAD risk,and the prognostic value of sCLEC-2 may be evaluated in future prospective studies. | Min Fei Li Xiang Xichen Chai Jingchun Jin Tao You Yiming Zhao Changgeng Ruan Yiwen Hao Li Zhu | 2020 | Frontiers of Medicine2020，14，1： | 5 |
| 3 | Genome-wide identification of agronomically important genes in outcrossing crops using OutcrossSeq显示文摘Many important crops(e.g.,tuber,root,and tree crops)are cross-pollinating.For these crops,no inbred lines are available for genetic study and breeding because they are self-incompatible,clonally propagated,or have a long generation time,making the identification of agronomically important genes difficult,particularly in crops with a complex autopolyploid genome.In this study,we developed a method,OutcrossSeq,for mapping agronomically important loci in outcrossing crops based on whole-genome low-coverage resequencing of a large genetic population,and designed three computation algorithms in OutcrossSeq for different types of outcrossing populations.We applied OutcrossSeq to a tuberous root crop(sweet potato,autopolyploid),a tree crop(walnut tree,highly heterozygous diploid),and hybrid crops(double-cross populations)to generate high-density genotype maps for the outcrossing populations,which enable precise identification of genomic loci underlying important agronomic traits.Candidate causative genes at these loci were detected based on functional clues.Taken together,our results indicate that OutcrossSeq is a robust and powerful method for identifying agronomically important genes in heterozygous species,including polyploids,in a cost-efficient way.The OutcrossSeq software and its instruction manual are available for downloading at www.xhhuanglab.cn/tool/OutcrossSeq.html. | Mengjiao Chen Weijuan Fan Feiyang Ji Hua Hua Jie Liu Mengxiao Yan Qingguo Ma Jiongjiong Fan Qin Wang Shufeng Zhang Guiling Liu Zhe Sun Changgeng Tian Fengling Zhao Jianli Zheng Qi Zhang Jiaxin Chen Jie Qiu Xin Wei Ziru Chen Peng Zhang Dong Pei Jun Yang Xuehui Huang | 2021 | Molecular Plant2021，14，4： | 4 |
| 4 | Differences of the oxidation process and secondary organic aerosol formation at low and high precursor concentrations显示文摘Current atmospheric quality models usually underestimate the level of ambient secondary organic aerosol(SOA), one of the possible reasons is that the precursors at different concentrations may undergo different oxidation processes and further affect SOA formation. Therefore, there is a need to perform more chamber studies to disclose the influence. In this work, SOA formation over a wide range of initial precursor concentrations(tens of ppb to hundreds of ppb levels) was investigated in a 30 m3 indoor smog chamber,and mainly through the analysis of multiple generations of VOCs detected from HR-To FPTRMS to expound the difference in the oxidation process between low and high precursor concentrations. Compared to high initial concentrations, gas-phase intermediates formed at low concentrations had a higher intensity by about one order of magnitude, and the lowvolatility compounds also had a higher formation potential due to the competition between semi-volatile intermediates and precursors with oxidants. In addition, the formed SOA was more oxidized with higher f44 value(0.14 ± 0.02) and more relevant to real atmosphere than that formed at high concentrations. This work should help to deeply understand SOA formation and improve the performance of air quality models for SOA simulation. | Tianzeng Chen Yongchun Liu Biwu Chu Changgeng Liu Jun Liu Yanli Ge Qingxin Ma Jinzhu Ma Hong He | 2019 | Journal of Environmental Sciences2019，31，5： | 4 |

| 6 | Vesicle-related OsSEC27P enhances H^+ secretion in the iron deficient transgenic tobacco root显示文摘Iron is an essential micronutritional element for plants.In addition to the iron uptake mechanism Strategy Ⅰ and Strategy Ⅱ,the vesicle transport process was also found to participate in iron uptake and homeostasis.Herein,a new iron deficiency induced OsSEC27P gene was isolated and investigated in both its localization and its function in transgenic plants.The vesicle-related protein OsSEC27P may play a potential role in enhancing H+ secretion in roots under the iron deficiency conditions. | YANG Guang MA Feng WANG Yi FENG ChangGeng LI Peng XU Yue ZHAO WeiZhong YIN LiPing | 2010 | Chinese Science Bulletin2010，55，29： | 2 |
| 7 | Fractal characterization and frequency properties of near-fault ground motions显示文摘This study explores the irregularity and complexity of strong earthquake ground motions from the perspective of fractal geometry,and constructs a relation with the frequency content of the ground motions.The box-counting fractal dimensions and five representative period parameters of near-fault ground motions from the Chi-Chi and Northridge earthquakes are calculated and compared.Numerical results indicate that the acceleration and velocity time histories of ground motions present the statistical fractal property,and the dominant pulses of near-fault ground motions have a significant influence on their box dimensions and periods.Further,the average box dimension of near-fault impulsive ground motions is smaller,and their irregular degree of wave forms is lower.Moreover,the box dimensions of ground motions reflect their frequency properties to a large extent,and can be regarded as an alternative indicator to represent their frequency content.Finally,the box dimension D of the acceleration histories shows a considerably negative correlation with the mean period T m.Meanwhile,the box dimension of the velocity histories D vel is negatively correlated with the characteristic period T c and improved characteristic period T gi. | Yang Dixiong Zhang Changgeng | 2013 | Earthquake Engineering and Engineering Vibration2013，12，4： | 2 |
