US Centers for Disease Control and Prevention (CDC) estimates food-borne pathogenic Salmonella bacteria cause about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the U.S. every year. Outbreaks of multidrug-resistant Salmonella Reading linked mainly to raw turkey products and alfalfa sprouts have accounted for human illness including mortality. Therefore, we downloaded and compared genome sequences of 897 Salmonella Reading isolated from 27 resources in 11 countries at 21 year-points from the National Center for Biotechnology Information database. Isolates were clustered into 10 clades which consisted of 3 major and 7 minor or single node clades. Although 3 major clades included both Europe and American isolates, one clade consisted of 605 North American isolates out of 614 isolates. Evolutionary distance is more related to the continent than the source of isolation. The host source, continent (North America and Europe) and phylogenetic clade were related to the prevalence of isolates encoding Antimicrobial Resistance Genes (ARGs). Prevalence of prophages was greater in bovine and swine isolates than poultry and human isolates and the least prevalence was found in human isolates. Between continents, the prevalence of phage was greater in North Ame- rican isolates than European. The diversity of virulence factors in swine isolates differed from poultry isolate while no difference was found among continents. In conclusion, evolutionary distance is related to isolation host source rather than the continent, and genome features were distinguished by host and cluster. Our genomic analysis implies that Salmonella Reading evolved independently to environments within its lineages.

Preparation of Novel Ultrathin Co doped MoS2 Nanosheets Piezocatalyst for Fast Simultaneous Decomposition of Cr(Ⅵ) and MB in Dark

引用

Chemical Research in Chinese Universities 2019年第5期35卷 892-900页

作者： WIN Thi yein WANG Qun JIAN Jiahuang LI Yang WU Xiaohong MIIT Key Laboratory of Critical Materials Technology for New Energy Conversion and Storage School of Chemistry and Chemical Engineerings Harbin Institute of Technology Harbin 150001P.R.China

Ultrathin Co doped MoS2 nanosheets(NSs) with thickness of 3.2 nm was used to simultaneously decompose Cr(Ⅵ) and MB in dark through ultrasonic vibration-assisted piezocatalytic effect. The significantly enhanced piezocatalytic performance of Co doped MoS2 NSs was found in comparison to the pristine MoS2 NSs. The high piezocatalytic activity of Co doped MoS2 NSs may originate from the large amount of charge carriers due to Co doping. The efficient separation of electron-hole pairs under spontaneous polarization were also investigated ill detail, which is responsible for reduction of Cr(Ⅵ) and oxidation of methylene blue(MB). The active species trapping experiments demonstrate that e and ·O2^- are main active substances for Cr(Ⅵ) reduction, while h+,·OH, and ·O2^- participate in MB degradation.

文章采用问卷调查和语装配对实验的方法,调查中国留学生与马来西亚大学生对马来西亚华语的态度,分析其共性与差异。问卷调查从已有文献中提取了七类马来西亚华语语法结构,分别调查了193位中国留学生与281位马来西亚华裔大学生。语装配对实验则针对马来西亚通俗华语与马来西亚标准华语,分别调查了183位中国留学生与272位马来西亚华裔大学生。调查结果显示:两组调查对象对七类语法结构的态度同中有异;居留时间是影响中国留学生对马来西亚华语态度的重要因素;两组调查对象对马来西亚标准华语的评分均高于马来西亚通俗华语。研究结果表明:马来西亚华语的标准变体是中马两国大学生普遍接受的变体;而通俗华语比标准华语更具情感价值。文章进一步讨论了地域、性别、居留时间三项社会因素对语言态度的影响,并从方法论的角度分析了问卷调查与语装配对实验在语言态度研究中的作用。普通话与华语说话人对马来西亚华语的语言态度的共性与差异有助于预测普通话与华语的融合,为全球华语跨区研究提供实证基础。

新疆小麦上分离到的大麦条纹花叶病毒(BSMV-XJ),经2.4%聚丙烯酰胺和0.5%琼脂糖凝胶电泳检出四个组分,与Argentina Mild 和North Dakota 161毒株的RNA 组分数相同。分离的BSMV-XJ 的单个RNA 组分没有侵染性,四个RNA 组分的混合物有侵染性,说明侵染性需要一个以上的RNA 组分。培养病毒的温度似对各组分的含量有影响。BSMV-XJRNA 经单分子展层后,在电镜下观察伸展的没有折迭卷曲的线状分子,其中有些分子长度约1,200～1,300毫微米,正好相当于其RNA 链的长度。
