1湖南会同寒武纪早期有机碳同位素地层学研究显示文摘寒武纪早期是地球海洋环境与生命演化的关键时期,但目前扬子东南缘深水相区的早寒武纪地层尚缺乏系统、精确的地层对比工作。该文选取湖南省怀化地区会同钻孔剖面(深水相区)的留茶坡组硅质岩、小烟溪组黑色页岩为研究对象,进行了高分辨的有机碳同位素(δ^(13)C_(org))地层对比,结果在会同剖面自下而上识别出四个正漂移(P1、P2、P3和P4)与两个负漂移(N1和N2),结合其他剖面的生物化石记录和锆石U-Pb年龄资料,将会同剖面有机碳同位素与湖南其他剖面,以及和云南和三峡等地浅水相区剖面的有机碳、无机碳同位素曲线进行对比,认为扬子东南缘埃迪卡拉系-寒武系界线在湖南深水相区可放置于留茶坡组上部较大的有机碳同位素负漂移(Basal Cambrian Carbon isotope Excursion,BACE)出现的位置,但由于钻孔深度不够,所以该负漂移未在会同剖面获得,而P1、P2和P3分别对应于寒武系的ZHUCE(ZHUjiaqing Carbon isotope Excursion,第二阶)、CARE(Cambrian Arthropod Radiation isotope Excursion,第三阶)和MICE(MIngxinsi Carbon Isotope Excursion,第四阶)正漂移,N1和N2分别对应于寒武系的SHICE(SHIyantou Carbon isotopeExcursion,第二阶)和AECE(Archaeocyathid Extinction Carbon isotope Excursion,第四阶)负漂移,因此会同剖面留茶坡组顶部至小烟溪组底部属于寒武系第二阶,小烟溪组下部属于寒武系第三阶,而小烟溪组中-上部属于寒武系第四阶,而顶部是否达到第四阶顶部尚无法确认。碳同位素的负漂移可能是海侵时期上升流水体将底层富含12C还原水体带至浅水地区所致,并分别与埃迪卡拉动物群、小壳化石动物群和古杯动物的灭绝密切相关;而在生物繁盛时期,海洋初级生产力升高,有机质埋藏增加,导致碳同位素的正漂移。王丹 凌洪飞 ULRICH Struck 姚素平 李达 卫炜 魏广祎 2016高校地质学报2016,22,2:5
2Hepatitis C virus genotypes distribution and transmission risk factors in Luxembourg from 1991 to 2006显示文摘AIM:To analyze the Hepatitis C virus (HCV) genotype distribution and transmission risk factors in a population of unselected patients in Luxembourg. METHODS:Epidemiological information (gender, age and transmission risks) were collected from 802 patients newly diagnosed for hepatitis C and living in Luxembourg, among whom 228 patients referred from prison. Genotyping using 5'noncoding (5'NC) sequencing was performed. We compared categorical data using the Fisher's exact F-test and odds ratios (OR) were calculated for evaluating association of HCV genotype and risk factors. RESULTS:The sex ratio was predominantly male (2.2) and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant (53.4%) followed by genotype 3 (33%). Among risk factors, intravenous drug usage (IVDU) was the most frequently reported (71.4%) followed by medical-related transmission (17.6%) including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU (OR = 4.84, P < 0.0001) whereas genotype 1 was significantly associated with a medical procedure (OR = 2.42, P < 0.001). The HCV genotype distribution from inmate patients differed significantly from the rest of the population (Chi-square test with four degrees of freedom, P < 0.0001) with a higher frequency of genotype 3 (46.5% vs 27.5%) and a lower frequency of genotype 1 and 4 (44.7% vs 56.8% and 5.3% vs 9.6%, respectively). IVDU was nearly exclusively reported as a risk factor in prison. CONCLUSION:We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European countries, with one of the highest European prevalence rates of genotype 3 (33%). Since serology screening became available in 1991, IVDU remains the most common way of HCV transmission in Luxembourg.Francois Roman Karin Hawotte Daniel Struck Anne-Marie Ternes Jean-Yves Servais Vic Arendt Patrick Hoffman Robert Hemmer Thérèse Staub Carole Seguin-Devaux Jean-Claude Schmit 2008World Journal of Gastroenterology2008,14,8:3

5Rationally engineered 3D-dendritic cell-like morphologies of LDH nanostructures using graphene-based core-shell structures显示文摘Functionalization of graphene-based materials using chemical moieties not only modify the electronic structure of the underlying graphene but also enable in limited enhancement of targeted properties.Surface modification of graphene-based materials using other nanostructures enhances the effective properties by minimally modifying the properties of pristine graphene backbone.In this pursuit,we have synthesized bio-inspired hierarchical nanostructures based on Ni–Co layered double hydroxide on reduced graphene oxide core–shells using template based wet chemical approach.The material synthesized have been characterized structurally and electrochemically.The fabricated dendritic morphology of the composite delivers a high specific capacity of 1056 Cg^(−1).A cost effective solid state hybrid supercapacitor device was also fabricated using the synthesized electrode material which shows excellent performance with high energy density and fast charging capability.Karthik Kiran Sarigamala Shobha Shukla Alexander Struck Sumit Saxena 2019Microsystems & Nanoengineering2019,5,1:2
