2Evaluation of three-dimensional biofilms on antibacterial bonding agents containing novel quaternary ammonium methacrylates显示文摘Antibacterial adhesives are promising to inhibit biofilms and secondary caries.The objectives of this study were to synthesize and incorporate quaternary ammonium methacrylates into adhesives,and investigate the alkyl chain length effects on three-dimensional biofilms adherent on adhesives for the first time.Six quaternary ammonium methacrylates with chain lengths of 3,6,9,12,16 and 18were synthesized and incorporated into Scotchbond Multi-Purpose.Streptococcus mutans bacteria were cultured on resin to form biofilms.Confocal laser scanning microscopy was used to measure biofilm thickness,live/dead volumes and live-bacteria percentage vs.distance from resin surface.Biofilm thickness was the greatest for Scotchbond control;it decreased with increasing chain length,reaching a minimum at chain length 16.Live-biofilm volume had a similar trend.Dead-biofilm volume increased with increasing chain length.The adhesive with chain length 9 had 37%live bacteria near resin surface,but close to 100%live bacteria in the biofilm top section.For chain length 16,there were nearly 0%live bacteria throughout the three-dimensional biofilm.In conclusion,strong antibacterial activity was achieved by adding quaternary ammonium into adhesive,with biofilm thickness and live-biofilm volume decreasing as chain length was increased from 3 to 16.Antibacterial adhesives typically only inhibited bacteria close to its surface;however,adhesive with chain length 16 had mostly dead bacteria in the entire three-dimensional biofilm.Antibacterial adhesive with chain length 16 is promising to inhibit biofilms at the margins and combat secondary caries.Han Zhou Michael D Weir Joseph M Antonucci Gary E Schumacher Xue-Dong Zhou Hockin H K Xu 2014International Journal of Oral Science2014,6,2:5
3参与式管理解决冲突:遥感和GIS用作瑞典北部驯鹿业土地利用需求信息交流的工具显示文摘在解决复杂的土地管理问题时,对短缺或者有争执的资源进行地理评估有助于不同利益相关者之间沟通认识和增进理解。本文中,我们说明如何使用遥感和GIS收集和汇总瑞典北部驯鹿放牧者和其他土地使用者(林业、采矿业、旅游业等等)的土地使用活动及使用模式的信息。该项目主要基于最终的土地使用者,即驯鹿放牧者们所做的工作,体现了面向土地使用者的新的努力。发展驯鹿业的土地利用规划的基础有以下几个方面:收集并数字化传统的驯鹿栖息地生态学和景观信息;将这些信息与来自野外调查及基于人造卫星观测的植被分类结果整合;绘制其他土地使用者的活动情况图。最终的土地利用规划提供的信息有利于驯鹿放牧者与其他利益相关者之间的磋商,并有助于驯鹿管理实施。该项目可作为一种大众参与和计划编制的模式,从而使本土信息和先进的遥感技术融入一个交互式的过程中。Per Sandstrm Tina Granqvist Pahlén Lars Edenius Hans Tφmmervik Olle Hagner Leif Hemberg Hkan Olsson Karin Baer Thomas Stenlund Lars Gran Brandt Mikael Egberth 周立志 程利群 2003AMBIO-人类环境杂志2003,32,8:4
4残余应力导致三层聚烯烃管道防腐层剥离与开裂显示文摘这是美国运输部发起的研究项目,一个管道防腐层专家团队参与了本研究项目,评价了三层聚烯烃管道外防腐涂层(3LPO)的完整性。研究表明,三层聚烯烃管道外防腐涂层(3LPO)存在剥离和面层开裂两大完整性问题。过去几年里,据文献报道,三层聚烯烃管道外防腐涂层(3LPO)的熔结环氧粉末(FBE)底漆与钢管界面上发生多起防腐层剥离事故,以及聚丙烯(PP)面层发生开裂事故。这些防腐层事故引起人们对使用三层聚烯烃管道外防腐涂层(3LPO)的关注。一般来讲,三层聚烯烃管道外防腐涂层(3LPO)采用比较厚的聚烯烃面层增强防腐层抗机械损伤和防止水渗透的能力。但是,聚烯烃的热膨胀系数比钢材高得多,结果在防腐层系统里产生比较高的残余热应力。因为残余应力高,造成防腐层剥离,尤其在管端截短防腐层和任何防腐层的边上,因为这些是高应力集中部位。特别是假如钢管表面预处理不当,就无法保证防腐层持久达到很强的粘合强度。如果熔结环氧粉末(FBE)底漆配方选择不当,发生热氧化降解,也导致防腐层过早失效。如果使用温度很高,聚丙烯也会因为热氧化降解而变脆。在残余应力下,这样脆性的聚丙烯面层就会开裂。本文分析了三层聚烯烃管道外防腐涂层(3LPO)中的残余应力,并且探讨了残余应力对三层聚烯烃管道外防腐涂层(3LPO)剥离和聚丙烯(PP)面层开裂机理的影响。B.T.A.Cheng S Hung-jue J Han D Wong A Kehr M Mallozzi F Aguirre H Pham W Snider 王向农(译) 2011防腐保温技术2011,19,3:3

6前列腺癌pT3亚型细分建议:精囊侵犯加前列腺腺外扩散比单独精囊侵犯的生化复发和淋巴结转移率更高显示文摘2020年美国前列腺癌发病率为21%,病死率为10%。术前血清PSA、预后分期肿瘤淋巴结转移、手术切缘状态和组织学分级[格里森评分和国际泌尿外科病理学会(ISUP)分组]被列为最高级别(Ⅰ类)证据。AJCC第8版TNM分期将前列腺癌pT3分为pT3a和pT3b,前者仅前列腺腺外扩散(EPE),后者为精囊侵犯(SVI)伴或不伴EPE。方三高(摘译) 魏建国(审校) Rehman A El-Zaatari Z M Han S H 2022临床与实验病理学杂志2022,38,3:2
