1四种粘结材料对纤维桩在不同深度根管内的固位力的影响——薄片推出实验显示文摘目的:比较4种不同树脂粘结材料在不同深度根管内粘固纤维桩的推出强度。方法:28个单根管离体前牙截冠后行根管充填和桩道预备,随机分为4组,分别用不同的粘结材料(Ⅰ:XP Bond-Dual Cure+Calibra resincement;Ⅱ:XP Bond-Dual Cure+Fluorocore2;Ⅲ:Excite DSC+MultiCore Flow;Ⅳ:Multilink Primer A/B+MultilinkAutomix)粘固纤维桩。粘固了纤维桩的牙根切割为1mm厚的试件并将其按照根管的深度分为上部、中部和下部3组,测试其推出强度。结果:Ⅰ组、Ⅱ组上部的推出强度均显著高于下部(P<0.05),Ⅲ组、Ⅳ组的推出强度在不同深度根管间无显著性差异(P>0.05)。结论:材料的类型和根管的深度对纤维桩的固位有影响。张凌 陈吉华 Elisa Magni Ivana Radovic Marco Ferrari 2007口腔医学研究2007,23,6:7
2多色荧光碳量子点的合成及不同链长度烃的功能化改性(英文)显示文摘以多壁碳纳米管(MWCNTs)为原料,经肽键形成氨基功能化后合成出新型多色荧光碳量子点(CQDs)。所制CQDs由准球形石墨纳米晶体(平均尺寸为10 nm)包裹不同烃类,如丙胺、辛胺、十二胺和八乙胺得到的氨基。在CQDs表面引入氮原子和烃类对其荧光性能、量子产率和溶解性起重要影响。这种新型有机-溶解CQDs的荧光发射波长取决于激发波长。荧光量子产率根据CQDs表面上烃类取代物的链长而变化。Kayo Oliveira Vieira Jefferson Bettini Luiz Fernando Cappa de Oliveira Jefferson Luis Ferrari Marco Antonio Schiavon 2017新型炭材料2017,32,4:5
3Study of risk factors for gastric cancer by populational databases analysis显示文摘AIM:To study the association between the incidence of gastric cancer and populational exposure to risk/protective factors through an analysis of international databases.METHODS:Open-access global databases concerning the incidence of gastric cancer and its risk/protective factors were identified through an extensive search on the Web.As its distribution was neither normal nor symmetric,the cancer incidence of each country was categorized according to ranges of percentile distribution.The association of each risk/protective factor with exposure was measured between the extreme ranges of the incidence of gastric cancer(under the 25th percentile and above the 75th percentile)by the use of the Mann-Whitney test,considering a significance level of0.05.RESULTS:A variable amount of data omission was observed among all of the factors under study.A weak or nonexistent correlation between the incidence of gastric cancer and the study variables was shown by a visual analysis of scatterplot dispersion.In contrast,an analysis of categorized incidence revealed that the countries with the highest human development index(HDI)values had the highest rates of obesity in males and the highest consumption of alcohol,tobacco,fruits,vegetables and meat,which were associated with higher incidences of gastric cancer.There was no significant difference for the risk factors of obesity in females and fish consumption.CONCLUSION:Higher HDI values,coupled with a higher prevalence of male obesity and a higher per capita consumption of alcohol,tobacco,fruits,vegetables and meat,are associated with a higher incidence of gastric cancer based on an analysis of populational global data.Fangio Ferrari Marco Antonio Moura Reis 2013World Journal of Gastroenterology2013,19,48:4
4Unscrambling light-automatically undoing strong mixing between modes显示文摘Propagation of light beams through scattering or multimode systems may lead to the randomization of the spatial coherence of the light.Although information is not lost,its recovery requires a coherent interferometric reconstruction of the original signals,which have been scrambled into the modes of the scattering system.Here we show that we can automatically unscramble optical beams that have been arbitrarily mixed in a multimode waveguide,undoing the scattering and mixing between the spatial modes through a mesh of silicon photonics tuneable beam splitters.Transparent light detectors integrated in a photonic chip are used to directly monitor the evolution of each mode along the mesh,allowing sequential tuning and adaptive individual feedback control of each beam splitter.The entire mesh self-configures automatically through a progressive tuning algorithm and resets itself after significantly perturbing the mixing,without turning off the beams.We demonstrate information recovery by the simultaneous unscrambling,sorting and tracking of four mixed modes,with residual cross-talk of−20 dB between the beams.Circuit partitioning assisted by transparent detectors enables scalability to meshes with a higher port count and to a higher number of modes without a proportionate increase in the control complexity.The principle of self-configuring and self-resetting in optical systems should be applicable in a wide range of optical applications.Andrea Annoni Emanuele Guglielmi Marco Carminati Giorgio Ferrari Marco Sampietro David AB Miller Andrea Melloni Francesco Morichetti 2017Light(Science & Applications)2017,6,1:4

9Genetic distinctions between autoimmune hepatitis in Italy and North America显示文摘AIM: Our goals were to analyze the known genetic predispositions for autoimmune hepatitis (AIH) in AIH Italian population and to compare them with North American counterparts.METHODS: Human leukocyte antigens (HLA) B8, C7, DR3,DR4, DR7, DR11, DR13, DQ2 and the B8-DR3-DQ2phenotype were determined by microlymphocytotoxicity and polymerase chain reaction in 74 Italian patients (57with type 1 and 17 with type 2 AIH) and 149 North American patients with type 1 AIH, and in adequate controls.RESULTS: B8-DR3-DQ2 occurred more frequently in Italian patients with type 1 AIH than in Italian controls (30% vs 7%, P<0.0001), but less frequently than in North American counterparts (30% vs48%, P = 0.02). DR4 occurred less frequently in Italian patients with type 1 AIH (23% vs43%,P= 0.01) and in controls (16% vs34%, P= 0.0003) than in North American counterparts. No differences were found in alleles' frequency between type 1 and type 2Italian AIH patients. DR11 had a frequency lower in type 1 Italian AIH patients than controls (17% vs35%, P= 0.01).CONCLUSION: HLA DR4 is not associated with AIH in Italy. The known HLA risk factors for ATH occur similarly in Italian patients with type 1 and type 2 AIH, and they are less frequent than in North American patients. B8-DR3-DQ2 is the predominant phenotype of type 1 AIH also in Italy, and HLA DR11 may be a regionally distinctive protective factor against type 1 AIH.Paolo Muratori Albert J.Czaja Luigi Muratori Georgios Pappas Silvana Maccariello Fabio Cassani Alessandro Granito Rodolfo Ferrari Vilma Mantovani Marco Lenzi Francesco B.Bianchi 2005World Journal of Gastroenterology2005,11,12:2
