| 1 | Changes of Aroma Components in 'Keitt' Mango during the Postharvest Period显示文摘[Objective]This study aimed to investigate the changes of aroma components in mango fruit at different post-harvest stages.[Method]The aroma components in‘Keitt'mango fruit at 3,6,9 and 13 d postharvest were extracted using head-space solid phase microextraction( HS-SPME) and analyzed by gas chromatograph-mass spectrophotometer( GC-MS).[Result]The results showed that a total of 42 aroma compounds were identified from the mango samples at four stages. To be specific,monoterpene and sesquiterpene were the major components; at 3,6,9 and 13 d postharvest,the relative contents of terpene were 94. 24%,98. 91%,55. 32% and 95. 97%,respectively.[Conclusion]1S-( +)-3-carene is the characteristic aroma component in ripe fruit of‘Keitt'mango. The aroma of mango fruit is also affected by ester,alcohol and aldehyde compounds. | Yigang ZHOU Hongxia WU Quansheng YAO Songbiao WANG Changbin WEI Xiaowei MA | 2014 | Agricultural Biotechnology2014，3，2： | 1 |
| 2 | The impacts of oxytetracycline on humification during manure composting can be alleviated by adjusting initial moisture contents as illustrated by NMR显示文摘Oxytetracycline(OTC)residues have been found in soil and water,and they may pose potential risks to agricultural ecological environments.One of the most impactful ways for OTC to enter the soil and water environments is through excrement used as organic fertilizer.Therefore,it is important to remove OTC during manure composting and to understand the transformation of the organic materials during composting in the presence of OTC.In the present paper,chicken manure and wheat sawdust spiked with OTC were composted under different initial moisture contents(MC)to evaluate the degradation of OTC and changes of organic matter during the composting process.The MC has a significant effect on OTC degradation during composting.A higher MC of 65% was more conducive to OTC degradation(77.4%)and compost maturity compared to the lower MC.However,the higher MC of 65%could increase the ammonia volatilization by promoting nitrification compared to the lower MC.An increase in the initial MC could improve the composting temperature.NMR results illustrated that the presence of OTC could affect the internal transformation of aliphatics,and OTC inhibited compost humification.Thus,an initial MC of 55–65% can alleviate the impacts of OTC on humification during manure composting. | FENG Yao WANG Gui-zhen LIU Yuan-wang CHENG Deng-miao FAN Shuang-hu ZHAO Quansheng Jianming XUE ZHANG Shu-qing LI Zhao-jun | 2021 | Journal of Integrative Agriculture2021，20，8： | 1 |
| 3 | Genome and epigenome editing identify CCR9 and SLC6A20 as target genes at the 3p21.31 locus associated with severe COVID-19显示文摘Dear Editor,The coronavirus disease 2019(COVID-19)pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is a major global health threat.Mortality is predominantly caused by severe respiratory failure related to interstitial pneumonia in both lungs and acute respiratory distress syndrome.Recently,genome-wide association studies(GWASs)have identified chromosome 3p21.31(sentinel variant:rsl 1385942)to be associated with both severe and general affected COVID-19 cases. | Yao Yao Fei Ye Kailong Li Peng Xu Wenjie Tan Quansheng Feng Shuquan Rao | 2021 | Signal Transduction and Targeted Therapy2021，6，3： | 0 |
| 4 | Role of intrinsic defects on carbon adsorbent for enhanced removal of Hg^(2+)in aqueous solution显示文摘Carbon is a normally used adsorbent for removal of heavy metal ion in aqueous solutions,but the efficient adsorbent needs intensive modification by heteroatom doped or supported noble metals that cause severe pollution and easy leaching of active components during use.In this paper,the role of intrinsic defects on Hg^(2+)adsorption for carbon adsorbent was investigated.The maximum adsorbing capacity of defectrich carbon has been improved up to 433 mg·g^(-1)which is comparable to most of the modified carbon adsorbents via supported metal chloride or noble metal components.The basicity is increased with the content of defective sites and the strong chemical bonding can be formed via electron transformation between the defect sites with adsorbed Hg^(2+).The present study gives a direction to explore cheap and easily scale-up high-performance mercury adsorbents by simply tuning the intrinsic defective structure of carbon without the necessity to support metal or other organic compounds. | Liu He Yiyang Qiu Chu Yao Guojun Lan Na Li Huacong Zhou Quansheng Liu Xiucheng Sun Zaizhe Cheng Ying Li | 2023 | Chinese Journal of Chemical Engineering2023，61，9： | 0 |
