| 1 | GIS-based analysis of population exposure to PM2.5 air pollution-A case study of Beijing显示文摘PM_(2.5), formally defined as particulate matter with diameter less than 2.5 μm, is one of most harmful air pollutants threatening human health. Numerous epidemiological studies have shown that both short-term and long-term exposures to PM_(2.5) are strongly linked with respiratory diseases. In this study, various types of spatio-temporal data were collected and used to estimate the spatio-temporal variation of PM_(2.5) exposure in Beijing in 2014. The seasonal and daily variation of the population-weighted exposure level(PWEL) in 2014 was estimated and compared. The results show that the population exposure to ambient air pollution differs significantly in the four seasons, and the exposure levels in winter and spring are notably higher than the other seasons; the exposure level changes greatly from North to South, and each sub-district maintains similarity to neighboring sub-districts. | Zhao Liu Meihui Xie Kun Tian Peichao Gao | 2017 | Journal of Environmental Sciences2017，29，9： | 10 |
| 2 | Comparative Analysis of Nutrient Composition of Caulerpa lentillifera from Different Regions显示文摘This study investigated the difference of nutrient composition in Caulerpa lentillifera collected from different regions.The nutrient compositions of C.lentillifera from China's Hainan and Shandong provinces were determined and compared with those from Semporna(Malaysia),Sabah(Malaysia),Petchburi(Thailand),and two other species of seaweeds(Malaysia).The results showed that the polysaccharide and protein contents of C.lentillifera from Hainan(44.82%±0.98%and 12.5%±0.70%),Shandong(43.22%±1.42%and 14.7%±0.72%),Petchburi(59.27%±2.31%and 12.49%±0.30%),and Sabah(44.02%±2.01%and 19.38%±1.48%)were higher than those of Eucheuma cottonii(26.49%±3.01%and 9.76%±1.33%)and Sargassum polycystum(33.49%±1.70%and 5.40%±0.07%),respectively.The polyunsaturated fatty acid contents in C.lentillifera from Hainan(29.98%)and Shandong(22.11%)were higher than that in Semporna(16.76%±0.27%),Sabah(9.49%),and S.polycystum(20.34%±0.43%),but lower than that in E.cottonii(51.55%±0.57%).In Caulerpa lentillifera of Hainan and Shandong provinces,the essential amino acid(EAA)/total amino acid(TAA)ratios were 35.22%and 38.78%,respectively;and the EAA/ETAA ratios were 54.36%and 63.35%,respectively.The EAA composition of C.lentillifera was close to the ideal model of Food and Agriculture Organization/World Health Organization.C.lentillifera was rich in mineral elements,including calcium((3315.85±127.55)mg(100 g)^-1 and(3728.35±92.38)mg(100 g)^-1),magnesium((6715.74±82.58)mg(100 g)^-1 and(8128.59±242.72)mg(100 g)^-1),and trace elements,including iron((510.65±5.47)mg(100 g)^-1 and(1972.97±183.35)mg(100 g)^-1),selenium((1.04±0.08)mg(100 g)^-1 and(0.83±0.15)mg(100 g)^-1),and zinc((33.90±0.13)mg(100 g)^-1 and(11.75±2.05)mg(100 g)^-1).These results showed that C.lentillifera was more nutritious than S.polycystum or E.cottonii in terms of polysaccharide,protein,and fatty acid contents.Furthermore,both C.lentillifera species collected from Hainan and Shandong provinces show more basic nutrients.Therefore,C.lentillifera has important development and application prospects. | ZHANG Meijian MA Yurong CHE Xinyi HUANG Zumei CHEN Peng XIA Guanghua ZHAO Meihui | 2020 | Journal of Ocean University of China2020，19，2： | 8 |
| 3 | Patterning catalyst via inkjet printing to grow single-walled carbon nanotubes显示文摘Controlled growth of patterned single-walled carbon nanotubes (SWNTs) is an important issue in many applications. Herein, we demonstrated a method to pattern catalyst via inkjet printing for the growth of SWNTs, using metal salt solutions as the inks and an ordinary office-use printer. We printed water solutions of cobalt acetate on hydrophilic Si substrates and grew high quality SWNT films. The composition of the precursor solutions and the hydrophilicity of the substrates were crucial factors to the patterning. | Zeyao Zhang Yitan Li Sheng Zhu Xiyan Liu Xiulan Zhao Meihui Li Haoyu Li Feng Yang Yan Li | 2019 | Chinese Chemical Letters2019，30，2： | 3 |
| 4 | Efficient base-free oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid over copper-doped manganese oxide nanorods with tert-butanol as solvent显示文摘2,5-Furandicarboxylic acid(FDCA)is an important and renewable building block and can serve as an alternative to terephthalic acid in the production of biobased degradable plastic.In this study,Cu-doped MnO_(2) nanorods were prepared by a facile hydrothermal redox method and employed as catalysts for the selective oxidation of 5-hydroxymethylfurfural(HMF)to FDCA using tert-butyl hydroperoxide(TBHP)as an oxidant.The catalysts were characterized using X-ray diffraction analysis,Fourier transform infrared spectroscopy,thermo-gravimetric analysis,and transmission electron microscopy.The effects of oxidants,solvents,and reaction conditions on the oxidation of HMF were investigated,and a reaction mechanism was proposed.Experimental results demonstrated that 99.4% conversion of HMF and 96.3% selectivity of FDCA were obtained under suitable conditions,and tert-butanol was the most suitable solvent when TBHP was used as an oxidant.More importantly,the Cu-doped MnO_(2) catalyst can maintain durable catalytic activity after being recycled for more than ten times. | Feng Cheng Dongwen Guo Jinhua Lai Meihui Long Wenguang Zhao Xianxiang Liu Dulin Yin | 2021 | Frontiers of Chemical Science and Engineering2021，15，4： | 2 |

| 7 | Dust transport information and paleoclimatic changes revealed by the loess in Ranwu,south-eastern Xizang显示文摘The loess accumulation process has great potential to record patterns of atmospheric circulation change,paleoclimate,and paleoenvironmental evolution.South-eastern Xizang is a climatically sensitive region and here,we analyze a loess profile at Ranwu in order to explore the processes and interactions of dust transport and paleoclimate evolution in the region.Based on parametric grain size end-member analysis,optically stimulated luminescence(OSL)dating,and environmental proxies we show that the Ranwu loess profile comprises five end members(EMs).EM1 represents the fine silt fraction transported by high-altitude westerly winds over long distances;EM2 represents the medium silt fraction accumulated by glacier winds;EM3 is the coarse silt fraction transported by local dust storms under the action of strong glacier winds;EM4 represents the very fine sand fraction transported by strong local dust storms,different wind strengths controls the relative proportion of EM3 and EM4 over time.EM5 is the coarse sand fraction formed from the product of strong weathering of gravels.OSL dating shows loess sedimentation at Ranwu started around 11.16 ka.The prevailing climate was generally warm and wet between 11.6 and 4.2 ka,with four cooling events at 10.50,9.18,7.85,and 6.37 ka.Extensive paleosol development between 8.2 and 4.2 ka,a change to dry and cold climate conditions was favorable for loess formation after 4.2 ka.The palaeoenvironmental changes and abrupt climate events recorded in the Ranwu loess sequence are consistent with Holocene global environmental changes. | Meihui PAN Huimin ZHAO Anna YANG Yougui CHEN Chenlu LI | 2023 | Frontiers of Earth Science2023，17，4： | 0 |
| 8 | Detecting SARS-CoV-2 BA.2,BA.4,and BA.5 Variants Utilizing a Robust RT-RPA-CRISPR/Cas12a-Based Method-China,2023显示文摘Introduction:Since 2019,numerous variants of concern for severe acute respiratory syndrome virus 2(SARS-CoV-2)have emerged,leading to significant outbreaks.The development of novel,highly accurate,and rapid detection techniques for these new SARSCoV-2 variants remains a primary focus in the ongoing efforts to control and prevent the coronavirus disease 2019(COVID-19)pandemic.Methods:Reverse transcription-recombinase polymerase amplification combined with the clustered regularly interspaced short palindromic repeatsassociated protein 12a(CRISPR/Cas12a)system was used to validate the detection of the Omicron BA.2,BA.4,and BA.5 variants of SARS-CoV-2.Results:Our results demonstrate that the CRISPR/Cas12a assay is capable of effectively detecting the SARS-CoV-2 BA.2,BA.4,and BA.5 variants with a limit of detection of 10,1,and 10 copies/μL,respectively.Importantly,our assay successfully differentiated the three SARS-CoV-2 Omicron strains from one another.Additionally,we evaluated 46 SARS-CoV-2 positive clinical samples consisting of BA.2(n=20),BA.4(n=6),and BA.5(n=20)variants,and the sensitivity of our assay ranged from 90%to 100%,while the specificity was 100%.Discussion:This research presents a swift and reliable CRISPR-based method that may be employed to track the emergence of novel SARS-CoV-2 variants. | Meihui Luo Yang Pan Yaqing He Ruhan A Changcheng Wu Baoying Huang Roujian Lu Li Zhao Bo Peng Fei Ye Huijuan Wang Yuda Chen Zhen Li Daitao Zhang Wenling Wang Wenjie Tan | 2023 | China CDC weekly2023，5，26： | 0 |
| 9 | Species-level Microbiota of Biting Midges and Ticks from Poyang Lake显示文摘Objective The purpose of this study was to investigate the bacterial communities of biting midges and ticks collected from three sites in the Poyang Lake area,namely,Qunlu Practice Base,Peach Blossom Garden,and Huangtong Animal Husbandry,and whether vectors carry any bacterial pathogens that may cause diseases to humans,to provide scientific basis for prospective pathogen discovery and disease prevention and control.Methods Using a metataxonomics approach in concert with full-length 16S rRNA gene sequencing and operational phylogenetic unit(OPU)analysis,we characterized the species-level microbial community structure of two important vector species,biting midges and ticks,including 33 arthropod samples comprising 3,885 individuals,collected around Poyang Lake.Results A total of 662 OPUs were classified in biting midges,including 195 known species and 373 potentially new species,and 618 OPUs were classified in ticks,including 217 known species and 326 potentially new species.Surprisingly,OPUs with potentially pathogenicity were detected in both arthropod vectors,with 66 known species of biting midges reported to carry potential pathogens,including Asaia lannensis and Rickettsia bellii,compared to 50 in ticks,such as Acinetobacter lwoffii and Staphylococcus sciuri.We found that Proteobacteria was the most dominant group in both midges and ticks.Furthermore,the outcomes demonstrated that the microbiota of midges and ticks tend to be governed by a few highly abundant bacteria.Pantoea sp7 was predominant in biting midges,while Coxiella sp1 was enriched in ticks.Meanwhile,Coxiella spp.,which may be essential for the survival of Haemaphysalis longicornis Neumann,were detected in all tick samples.The identification of dominant species and pathogens of biting midges and ticks in this study serves to broaden our knowledge associated to microbes of arthropod vectors.Conclusion Biting midges and ticks carry large numbers of known and potentially novel bacteria,and carry a wide range of potentially pathogenic bacteria,which may pose a risk of infection to humans and animals.The microbial communities of midges and ticks tend to be dominated by a few highly abundant bacteria. | GONG Jian WANG Fei Fei LIU Yang Qing PU Ji DONG Ling Zhi ZHANG Si Hui HUANG Zhen Zhou HUANG Yu Yuan LI Ya Ben YANG Cai Xin TAO Yuan Meihui ZHAO Li Jun JIN Dong LIU Li Yun YANG Jing LU Shan | 2024 | Biomedical and Environmental Sciences2024，37，3： | 0 |
