1Aflatoxins,hepatocellular carcinoma and public health显示文摘Hepatocellular carcinoma(HCC) is one of the leading causes of cancer deaths worldwide,primarily affecting populations in the developing countries.Aflatoxin,a food contaminant produced by the fungi Aspergillus flavus and Aspergillus parasiticus,is a known human carcinogen that has been shown to be a causative agent in the pathogenesis of HCC.Aflatoxin can affect a wide range of food commodities including corns,oilseeds,spices,and tree nuts as well as milk,meat,and dried fruit.Many factors affect the growth of Aspergillus fungi and the level of aflatoxin contamination in food.Drought stress is one of the factors that increase susceptibility of plants to Aspergillus and thus aflatoxin contamination.A recent drought is thought to be responsible for finding of trace amounts of aflatoxin in some of the corn harvested in the United States.Although it's too soon to know whether aflatoxin will be a significant problem,since United States is the world's largest corn producer and exporter,this has raised alarm bells.Strict regulations and testing of finished foods and feeds in the United States should prevent a major health scare,and prevent human exposure to deleterious levels of aflatoxin.Unfortunately,such regulations and testing are not in place in many countries.The purpose of this editorial is to summarize the current knowledge on association of aflatoxin and HCC,encourage future research and draw attention to this global public health issue.Arvin Magnussen Mansour A Parsi 2013World Journal of Gastroenterology2013,19,10:16
2Amphibians and Reptiles of Luzon Island,V:The Herpetofauna of Angat Dam Watershed,Bulacan Province,Luzon Island,Philippines显示文摘We report amphibian and reptile distribution records based on recent biodiversity surveys conducted at the Angat Watershed Reservation,Bulacan Province,Luzon Island,Philippines.This watershed constitutes the principal water source for Manila,the Philippines’largest metropolitan area.As virtually nothing is known of the herpetological diversity of the immediate area and the surrounding Bulacan Province,all species recorded as part of our surveys constitute major geographical records and/or significant range extensions.Our data result in a total of 63 new records of amphibian(19 frogs)and reptile(22 lizards,2 turtles,and 20 snakes)species for this protected area(and immediate vicinity)that serves as a watershed for the major metropolitan area of Manila and surrounding cities.Together with the few previous literature records,our new records bring the total number of amphibian and reptile species for Bulacan Province to 68.We discuss several strategies for future survey work(focusing on habitat type,seasonal variation,and elevational variability)that we anticipate will result in increased knowledge of diversity within the Angat Watershed Reserve.The impressive level of herpetological diversity within such a small area,so close to Metro Manila,emphasizes that the diversity and distribution patterns of amphibians and reptiles from Luzon are still poorly known and in need of further study.David S.MCLEOD Cameron D.SILER Arvin C.DIESMOS Mae L.DIESMOS Vhon S.GARCIA Angela O.ARKONCEO Kelvin L.BALAQUIT Charlene C.UY Mariden M.VILLASERAN Earle C.YARRA Rafe M.BROWN 2011Asian Herpetological Research2011,2,4:4

4脂氧素A4调控mRNA-29b保护脂多糖诱导大鼠急性肺损伤的机制研究显示文摘目的探讨脂氧素A4(LXA4)调控miRNA-29家族分子保护脂多糖(LPS)诱导大鼠急性肺损伤(特征性表现为急性呼吸窘迫综合征)的机制。方法将30只SD大鼠按随机数字表法分为LPS组(按20mg/kg尾静脉注射LPS)、LPS+LXA4组(按20mg/kg尾静脉注射LPS 6h后,再按2μg/kg尾静脉注射LXA4作用2h)和对照组(予等量0.9%氯化钠注射液),每组10只。麻醉处死大鼠取肺,左肺用于HE染色和ELISA法检测促炎因子(TNF-α、IL-6)水平,右肺用于RT-PCR法检测miRNA-29家族表达水平。结果 LPS组大鼠肺组织切片可见明显的炎症改变,肺损伤评分及肺组织内TNF-α、IL-6水平较对照组均明显升高(均P<0.05)。LPS+LXA4组大鼠肺组织切片可见炎症反应减轻,肺损伤评分及肺组织内TNF-α、IL-6水平较LPS组均明显下降(均P<0. 05)。RT-PCR结果显示,LPS组大鼠肺组织内miRNA-29a、miRNA-29b表达水平均明显升高(均P<0. 05),LPS+LXA4组miRNA-29b表达水平明显下降(P<0.05)。结论 miRNA-29a、miRNA-29b可能在LPS诱导的大鼠急性肺损伤炎症发生过程中起着调节作用,LPS可能通过下调miRNA-29b表达来发挥促炎症消退的作用。纪伟平 Hui Li Arvine Chandoo 蔡爱敏 董佩泓 吴晓燕 2019浙江医学2019,41,2:3
5Global assessment of nitrogen fertilizer:The SCOPE/IGBP Nitrogen Fertilizer Rapid Assessment Project显示文摘Nitrogen (N) availability is a key role in food and fiber production. Providing plant-available N through synthetic fertilizer in the 20th and early 21st century has been a major contributor to the increased production required to feed and clothe the growing human population.To continue to meet the global demands and to minimize environmental problems, significant improvements are needed in the efficiency with which fertilizer N is utilized within production systems. There are still major uncertainties regarding the fate of fertilizer N added to agricultural soils and the potential for reducing losses to the environment. Enhancing the technical and economic efficiency of fertilizer N is seen to promote a favorable situation for both agricultural production and the environment, and this has provided much of the impetus for a new N fertilizer project.To address this important issue, a rapid assessment project on N fertilizer (NFRAP) was conducted by SCOPE (the Scientific Committee on Problems of the Environment) during late 2003 and early 2004. This was the first formal project of the International Nitrogen Initiative (INI). As part of this assessment, a successful international workshop was held in Kampala, Uganda on 12 -16 January, 2004. This workshop brought together scientists from around the world to assess the fate of synthetic fertilizer N in the context of overall N inputs to agricultural systems, with a view to enhancing the efficiency of N use and reducing negative impacts on the environment.Regionalization of the assessment highlighted the problems of too little N for crop production to meet the nutrient requirements of sub-Saharan Africa and the oversupply of N in the major rice-growing areas of China. The results of the assessment are presented in a book (SCOPE 65)which is now available to provide a basis for further discussions on N fertilizer.Arvin R.Mosier J.Keith Syers John R.Freney 2005Science China(Life Sciences)2005,48,z2:3
6胃癌围手术期双向转诊协作模式的实践显示文摘目的探索三甲医院-基层卫生机构胃癌围手术期双向转诊模式。方法选取2016年5月到2017年5月温州周围区(县)级(含)以下基层医疗卫生机构向温州某大型三甲综合性医院转诊按照'基层-三甲医院-基层'围手术期相互转诊方案的胃癌患者32例作为试验组,选取温州周围区(县)级(含)以下基层医疗卫生机构通过普通方式转诊到温州某大型三甲综合性医院的胃癌患者51例作为对照组,收集相关数据,并进行统计分析。结果试验组对双向转诊的周围区(县)级(含)以下基层医疗卫生机构人员的技术水平及服务态度[(43.00±1.75)、(27.00±2.78)分],温州某大型三甲综合性医院医务人员的接诊情况及服务态度的满意度[(46.00±1.52)、(32.00±2.37)分]均高于对照组,差异均有统计学意义(P<0.05)。试验组患者的住院时间明显少于对照组,差异无统计学意义(P>0.05)。试验组患者围手术期及手术总体花费均显著低于对照组,差异均有统计学意义(P<0.05)。试验组患者的术后并发症明显少于对照组,但差异无统计学意义(P>0.05)。结论科学合理的双向转诊能有效提高患者满意度,减少住院费用,较好地满足了患者日益增长的就医要求,有助于分级诊疗体系的建设与实现。纪伟平 卢明东 黄颖鹏 谷斌斌 张良 孙祥威 CHANDOO ARVINE 游涛 沈贤 2018现代医药卫生2018,34,6:3
7AZ31-O镁合金和6061-T6铝合金搅拌摩擦焊接头的显微组织和力学性能(英文)显示文摘对3 mum厚的AZ31-O镁合金板和6061-T6铝合金板进行异种材料搅拌摩擦焊.实验中搅拌针的旋转速度为600~1400 r/min,前进速度为20~60 mm/min.结果表明,在旋转速度1000 r/min、前进速度40 mm/min的工艺条件下,可以获得无缺陷的焊接接头.组织观察发现搅拌区的晶粒尺寸要比基材区的明显小很多.在搅拌区形成了复杂的金属流动.显微硬度测试表明搅拌区的硬度分别是不均匀的.拉伸实验结果表明,接头的拉伸强度约为基材AZ31镁合金的76%,或6061铝合金的60%.接头拉伸断口SEM形貌观察表明为脆性断裂.Alireza MASOUDIAN Arvin TAHAEI Atefeh SHAKIBA Fariborz SHARIFIANJAZI Jamshid Aghazadeh MOHANDESI 2014Transactions of Nonferrous Metals Society of China2014,24,5:3
