3Eleven COVID-19 Outbreaks with Local Transmissions Caused by the Imported SARS-CoV-2 Delta VOC-China,July-August,2021显示文摘Starting from December 2019,Wuhan,China,encountered the first outbreak of coronavirus disease 2019(COVID-19)(1-2).The epidemic was successfully suppressed by strict containment so that the number of infected people was reduced to 0 on April 8,2020(3–4).After that,China experienced roughly 3 dozen outbreaks with local transmission caused by imported severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Lei Zhou Kai Nie Hongting Zhao Xiang Zhao Bixiong Ye Ji Wang Cao Chen Hong Wang Jiangli Di Jinsong Li Chao Li Zhixiao Chen Ruiqi Ren Peihua Niu Hui Chen Tao Chen Yali Wang Lili Li Bingxue Han Ruhan A Si Chen Dan Li Dan Li Chunxia Jin Xin Zhang Jiangmei Liu Chunyu Xu Yecheng Yao Yenan Feng Zhili Li Bike Zhang Yang Song Peter Hao Yanping Zhang Hao Li Qun Li George F.Gao Guoqing Shi Wenbo Xu 2021China CDC weekly2021,3,41:13
4Identification of three major Bemisia tabaci biotypes in China based on morphological and DNA polymorphisms显示文摘The sweet potato whitefly, Bemisia tabaci, is a complex species, and many of its biotypes are important agricultural pests. The B and Q biotypes are invasive and coexist with the native Cv biotype on vegetable and ornamental crops in China. In this study, these three bio- types were identified based on their morphological characteristics, RAPD-PCR analysis, and DNA sequences of the COI gene. The ante-rior and posterior wax fringes of the B, Q, and Cv biotypes significantly differed from each other. Based on this morphological characteristic, the three biotypes can easily be distinguished in greenhouses and fields. Genomic DNA RAPD-PCR band patterns also revealed differences between these biotypes using the H16 primer. The B biotype has three bright DNA bands between 250 and 600 bp, the Q biotype only has one bright band at 300 bp, while the Cv biotype has no band between 250 and 500 bp. Both the Cv and Q biotypes have two bright bands at 750 and 1000 bp while the B biotype has only one band at 1000 bp. Based on the COI gene, the genetic identity between B and Cv, B and Q, and Q and CV was 85.8%, 94.7%, and 86.0%, respectively. The MP tree indicated that the phylogenetic relationship between the B and Q biotypes is much closer than that between the B and Cv or the Q and Cv biotypes. The uses of the morphological, RAPD-PCR, and DNA sequencing methods in biotype identification of B. tabaci are discussed.Baoli Qiu Yanping Chen Li Liu Weilu Peng Xiaoxi Li Muhammad Z.

5Effects of nitrogen ion implantation on Ca^(2+) concentration and membrane potential of pollen cell显示文摘The effects of low energy nitrogen ion implantation on Ca2+ concentration and membrane potential of illy (Mum davidii Duch) pollen cell have been studied. The results showed that the Ca2+ concentration was increased when pollen grain was implanted by nitrogen ion with energy 100 keV and dose 1013 ions/cm2. However, the increase of Ca2+ concentration was partly inhibited by the addition of Ca2+ channel inhibitor depending on dose. And nitrogen ion implantation caused depolarization of pollen cell membrane potential. In other words, membrane potential was increased, but the effect decreased by adding Ca2+ channel inhibitor. However, it was still significantly higher than the membrane potential of control cells. It was indicated that the depolarization of cell membrane potential opened the calcium channel on the membrane that caused the increasing of intracel-lular calcium concentration. This might be an earlier step of the effect of low energy nitrogen ion implantation on pollen germination.HUANG Zhonglian, JING Yanping, ZHU Guoli, LU Ting, ZHOU Hongyu & REN Haiyun1.

6On the viscosity of magnetic fluid with low and moderate solid fraction显示文摘The design of a pressurized capillary rheometer operating at prescribed temperature is described to measure the viscosity of magnetic fluids(MFs) containing Fe3O4 magnetic nanoparticles(MNPs).The equipment constant of the rheometer was obtained using liquids with predetermined viscosities.Experimentally measured viscosities were used to evaluate different equations for suspension viscosities.Deviation of measured suspension viscosities from the Einstein equation was found to be basically due to the influence of spatial distribution and aggregation of Fe3O4 MNPs.By taking account of the coating layer on MNPs and the aggregation of MNPs in MFs,a modified Einstein equation was proposed to fit the experimental data.Moreover,the influence of external magnetic field on viscosity was also taken into account.Viscosities thus predicted are in good agreement with experimental data.Temperature effect on suspension viscosity was shown experimentally to be due to the shear-thinning behavior of the MFs.Zhiqiang Ren Yanping Han Ruoyu Hong Jianmin Ding Hongzhong Li 2008Particuology2008,6,3:5
7Sources and Accumulation Risk of Heavy Metal in Major Animal Manure显示文摘Feed and corresponding manure samples were collected from 27 scale pig farms and 7 scale chicken farms in Jiaxing City,Zhejiang Province,and their heavy metal contents were analyzed. The weighted average values of Cr,Cu,Zn,Pb and As in pig feed were 4. 6,123. 4,370. 7,0. 69 and 6. 9 mg/kg,respectively. However,referred to Safe Use Specification of Feed Additives and MOA Announcement No. 1224,the exceeding standards rates of Cr,Cu,Zn,Pb and As in pig feed were 5. 36%,62. 5%,19. 64%,3. 57% and 37. 5%,respectively. The sequences of heavy metal content in pig feed successively were piglet > growing pig > big pig > sow,but the exceeding standard rates of heavy metal in feed were big pig > sow > growing pig > piglet,and the exceeding standard rate of big pig feed was more than 95%. The exceeding standard rates of Cu,Zn and As in chicken feed were 46. 7%,11. 1% and 33. 3% respectively. Based on Organic Fertilizer( NY525-2012) and Sludge Agricultural Pollution Control Standard( GB4284-84),Cu,Zn and As in pig manure and chicken manure exceeded the standard; the exceeding standard rates of pig manure were 71. 9%,78. 9% and 42. 1%,while that of chicken manure were 12. 5%,25. 0% and 44. 4%,respectively. The exceeding standard rates of Cu and Zn in piglet manure reached 100%. There were very significant positive correlations in Cu,Zn and As between pig feed and corresponding manure,or Hg,Cu and As between chicken feed and corresponding manure,and the correlation coefficients r^2 were greater than 0. 8. Besides,the correlation coefficient r^2 of Pb between pig feed and corresponding manure was above 0. 6. Continuous and high intensity of livestock manure application significantly promoted the accumulation of heavy metal in farmland soil,but the effects on heavy metal accumulation in rice was not significant.Shi Yanping Huang Jinfa Ni Xiongwei Xie Jianping Ren Jiajia 2016Animal Husbandry and Feed Science2016,8,6:4
8Aluminum neurotoxicity effects on intracellular Ca^(2+) homeostasis in the rat cerebral cortex显示文摘Studies have suggested that aluminum,a neurotoxic metal,is involved in the progression of neurodegenerative diseases.Previous studies have confirmed that aluminum influences intracellular Ca2+ homeostasis.However,it remains unclear whether aluminum increases or decreases intracellular Ca2+ concentrations.The present study demonstrated that Al3+ competitively binds to calmodulin(CaM),together with Ca2+,which resulted in loss of capacity of CaM to bind to Ca2+,leading to increased [Ca2+]i.Al3+ stimulated voltage-gated calcium channels on cell membranes,which allowed a small quantity of Ca2+ into the cells.Al3+ also promoted calcium release from organelles by stimulating L-Ca2+ α1c to trigger calcium-induced calcium release.Although Al3+ upregulated expression of Na+/Ca2+ exchanger mRNA,increased levels of Ca2+ and Na+/Ca2+ exchanger did not maintain a normal Ca2+ balance.Al3+ resulted in disordered intracellular calcium homeostasis by affecting calcium channels,calcium buffering,and calcium expulsion.Rui Ren Yang Zhang Xiaofeng Zhang Yanping Wu Dandan Zhang Baixiang Li 2010Neural Regeneration Research2010,5,15:3
9Distribution and segregation of dissolved elements in pipeline slab显示文摘The chemical composition in a cross section of a high grade pipeline slab was measured point by point (in a scale of 1 μm) using original position statistic distribution analysis (OPA). The result indicated that negative segregation strips of Si, Mn, Mo, Ni, Cr, Nb, Cu, Ti, and V exist in the two sides 24 mm away from the central line, with a width of 8-12 mm, Negative segregation inside the central line is more severe than that outside the central line, and the highest positive segregation of the elements appears closely by the inner sides of the negative segregation strips. No obvious negative segregation strip of S and P is found. Segregation of the elements in the central area is higher than that in the outer and inner arc areas. The segregation of C, Ti, S, and P is high and that of Cr, Cu, Si, and Mn is low in the slab.Jianhua Liu Yanping Bao Xian Dong Taiquan Li Yi Ren Shuai Zhang 2007Journal of University of Science and Technology Beijing2007,14,3:3
10Plant multiscale networks:charting plant connectivity by multi-level analysis and imaging techniques显示文摘In multicellular and even single-celled organisms,individual components are interconnected at multiscale levels to produce enormously complex biological networks that help these systems maintain homeostasis for development and environmental adaptation.Systems biology studies initially adopted network analysis to explore how relationships between individual components give rise to complex biological processes.Network analysis has been applied to dissect the complex connectivity of mammalian brains across different scales in time and space in The Human Brain Project.In plant science,network analysis has similarly been applied to study the connectivity of plant components at the molecular,subcellular,cellular,organic,and organism levels.Analysis of these multiscale networks contributes to our understanding of how genotype determines phenotype.In this review,we summarized the theoretical framework of plant multiscale networks and introduced studies investigating plant networks by various experimental and computational modalities.We next discussed the currently available analytic methodologies and multi-level imaging techniques used to map multiscale networks in plants.Finally,we highlighted some of the technical challenges and key questions remaining to be addressed in this emerging field.Xi Zhang Yi Man Xiaohong Zhuang Jinbo Shen Yi Zhang Yaning Cui Meng Yu Jingjing Xing Guangchao Wang Na Lian Zijian Hu Lingyu Ma Weiwei Shen Shunyao Yang Huimin Xu Jiahui Bian Yanping Jing Xiaojuan Li Ruili Li Tonglin Mao Yuling Jiao Sodmergen Haiyun Ren Jinxing Lin 2021Science China(Life Sciences)2021,64,9:3

12Genetic diversity of atoxigenic Aspergillus flavus isolates from peanut kernels in China显示文摘Aflatoxin contamination in peanuts is a major threat to public health, especially in tropical and subtropical regions of the world. Recently, the use of atoxigenic Aspergillus flavus strains as biological control agents prove to be effective in reducing aflatoxin contamination in crops. A total of 208 atoxigenic A. flavus isolates, collected from peanut kernels, were grouped into 7 deletion patterns by quadruplex PCR products of nor-1, ver-1, aflR and omtA genes. 49 SNPs, found in 1254 bp fragment of omtA gene, showed genetic variation of omtA among different A. flavus isolates. These isolates were assigned to either MAT1-1 type or MAT1-2 type with primers for each MAT locus. Thus, rich genetic diversity was found in the atoxigenic A. flavus isolates of peanut in China. The results indicated that quadruplex PCR would be an effective method for rapid screening of atoxigenic isolates with gene deletion in aflatoxin biosynthetic cluster.Liying Yan Yanping Kang Yong Lei Liyun Wan Dongxin Huai Huifang Jiang Xiaoping Ren Boshou Liao 2018Oil Crop Science2018,3,1:2

16CRISPR/Cas9-mediated mutagenesis of CiBG1 decreased seed size and promoted seed germination in watermelon显示文摘Abscisic acid(ABA)is a critical regulator of seed development and germination.β-glucosidases(BGs)have been suggested to be contributors to increased ABA content because they catalyze the hydrolysis of ABA-glucose ester to release free ABA.However,whether BGs are involved in seed development is unclear.In this study,a candidate gene,CiBG1,in watermelon was selected for targeted mutagenesis via the CRISPR/Cas9 system.Seed size and weight were significantly reduced in the Clbg1-mutant watermelon lines,which was mainly attributed to decreased cell number resulting from decreased ABA levels.A transcriptome analysis showed that the expression of 1015 and 1429 unique genes was changed 10 and 18 days after pollination(DAP),respectively.Cytoskeleton-and cell cycle-related genes were enriched in the differentially expressed genes of wild type and Clbg1-mutant lines during seed development.Moreover,the expression of genes in the major signaling pathways of seed size control was also changed.In addition,seed germination was promoted in the Cibg1-mutant lines due to decreased ABA content.These results indicate that ClBG1 may be critical for watermelon seed size regulation and germination mainly through the modulation of ABA content and thereby the transcriptional regulation of cytoskeleton-,cell cycle-and signaling-related genes.Our results lay a foundation for dissecting the molecular mechanisms of controlling watermelon seed size,a key agricultural trait of significant economic importance.Yanping Wang Jinfang Wang Shaogui Guo Shouwei Tian Jie Zhang Yi Ren Maoying Li Guoyi Gong Haiying Zhang Yong Xu 2021Horticulture Research2021,8,1:1

20Synchronization clusters located on epileptic onset zones in neocortical epilepsy显示文摘Background Brain function is thought to rely on complex interactions of dynamic neural systems,which depend on the integrity of structural and functional networks.Focal epilepsy is considered to result from excessive focal synchronization in the network.Synchronization analysis of multichannel electrocorticography(ECoG)contributes to the understanding of and orientation of epilepsy.The aim of this study was to explore the synchronization in multichannel ECoG recordings from patients with neocortical epilepsy and characterize neural activity inside and outside the onset zone.Methods Four patients with neocortical epilepsy,who became seizure-free for more than 1 year after surgery guided by ECoG monitoring,were included in this study.ECoG data recorded during pre-surgical evaluation were analyzed.Synchronizations in phase and amplitude of different frequency bands between ECoG channels was analyzed using MATLAB.We generated 100 surrogate data from the original ECoG data using Amplitude Adjusted Fourier Transform to calculate the enhanced synchronization.The relationship between synchronization characteristics and seizure onset zone was analyzed.Results We found synchronization clusters in the 14–30 Hz and 30–80 Hz bands around the onset areas during both interictal and the beginning of ictal periods in all four patients.Conclusions The enhanced-synchronization clusters play a central role in epilepsy,and may activate the onset areas and contribute to the spreading of epileptiform activity.Yanping Sun Yuqiang Song Hongjin Ren Haifang Zhu Yanning Wang Xiaoli Li Wenjing Yan Yuping Wang 2022Acta Epileptologica2022,5,4:1
