1Further support for a Cretaceous age for the feathered-dinosaur beds of Liaoning,China:New ^(40)Ar/^(39)Ar dating of the Yixian and Tuchengzi Formations显示文摘We report new 40Ar/39Ar dating results ob-tained from total fusion and incremental-heating analyses of sanidine and biotite from three tuffs found interbedded within the fossil-bearing deposits of Liaoning, northeast China. The first is a new sample of the Bed 6 Sihetun tuff from the Yixian Formation, previously dated by our team as middle Early Cretaceous, and recently considered by Lo et al., partially reset due to metamorphism from a nearby ba-saltic sill. The second is the Yixian Bed 9 tuff from Heng-daozi considered by Lo et al. to be unaffected by metamor-phism and whose age, based on total fusion 40Ar/39Ar dating of biotite, argues for a Jurassic age for the Yixian Formation. The third tuff is a previously undated tuff from the upper part of the underlying Tuchengzi Formation. Single crystal total fusion 40Ar/39Ar analyses of the Sihetun sanidine showed homogeneous radiogenic Ar, Ca/K ratios, excellent reproducibility and gave a mean age of 125.0 ± 0.18 (1SD) ± 0.04 (SE) Ma.

2Can intraluminal devices prevent or reduce colorectal anastomotic leakage:A review显示文摘Colorectal anastomotic leakage is a serious complication of colorectal surgery, leading to high morbidity and mortality rates. In recent decades, many strategies aimed at lowering the incidence of anastomotic leakage have been examined. The focus of this review will be on mechanical aids protecting the colonic anastomosis against leakage. A literature search was performed using MEDLINE, EMBASE, and The Cochrane Collaborative library for all papers related to prevention of anastomotic leakage by placement of a device in the colon. Devices were categorised as decompression devices, intracolonic devices, and biodegradable devices. A decompression device functions by keeping the anal sphincter open, thereby lowering the intraluminal pressure and lowering the pressure on the anastomosis. Intracolonic devices do not prevent the formation of dehiscence. However, they prevent the faecal load from contacting the anastomotic site, thereby preventing leakage of faeces into the peritoneal cavity. Many attempts have been made to find a device that decreases the incidence of AL;however, to date, none of the devices have been widely accepted.Annelien N Morks Klaas Havenga Rutger J Ploeg 2011World Journal of Gastroenterology2011,17,40:11
3水稻抗稻瘟病菌防卫反应的细胞学分析与防卫基因表达显示文摘对水稻类病变坏死突变体lmm1(LmmKaty)与原亲本及双单倍体YT14和YT16接种稻瘟病菌24h内的抗病反应、细胞学和分子作用机理进行了研究。人工接种实验表明,与原亲本相比,该突变体对稻瘟病菌具有更强的抗性。突变体接种20~24h后,自动荧光检测到细胞死亡,而对照则未检测到。表明该突变体通过细胞程序性死亡阻止稻瘟病菌的蔓延,从而提高了抗病性。Northernblotting结果发现,抗病品系YT14中的防卫相关基因、苯丙氨酸解氨酶基因和β-葡聚糖酶基因在人工接种稻瘟病菌6h后开始表达,16~24h后上述基因表达量快速增加;而病程相关蛋白基因PR-1和几丁质酶基因在人工接种稻瘟病菌24h后才开始表达。与YT14相比,感病品系中上述基因的表达明显延迟。表明在人工接种稻瘟病菌24h内水稻可启动抗病防卫反应,从而对稻瘟病菌产生抗性。王忠华 林卉 Barbara VALENT J.Neil RUTGER 贾育林 2007中国水稻科学2007,21,4:5
4富营养化对海底系统污染物循环的影响显示文摘本文研究了有机物质输入对波罗的海和卡特加特海峡海底生态系统疏水性有机污染物(HOC)生物利用度和循环的影响。通过实验,我们研究了由于紫胎贝(Mytilus edulis)、蛇尾虫(Amphiura filiformis)及多毛目环节动物(Nereis diversicolor)所引起的微藻增加对HOC(PCB和PAH)生物积累的影响。和平衡分配理论相反,生物积累与海藻和有机碳的浓度成正比。这是由海藻有机碳中营养质量高所造成的,同时也表明是取食而不是平衡分配控制了这些物种的生物积累。通过实地研究,我们估计了紫贻贝和蛇尾虫体内每年PCB的流通总量和每年转移到更高营养级的污染物的总量。研究结果指出:①富营养化能促进底栖生物体内HOC的积累。②在评价海底系统污染时,必需考虑有机碳质量和数量在时间上的变化。③大型动物的取食活动对海底和深海结合IIOC很重要。④生物扰动促进了HOC从沉积物向水面的释放。Jonas Gunnarsson Mikael Bjrk Michael Gilek Maria Granberg Rutger Rosenberg 王燕 2000AMBIO-人类环境杂志2000,29,4:4
5Polylogarithms and multiple zeta values from free Rota-Baxter algebras显示文摘We show that the shuffle algebras for polylogarithms and regularized MZVs in the sense of Ihara,Kaneko and Zagier are both free commutative nonunitary Rota-Baxter algebras with one generator.We apply these results to show that the full sets of shuffle relations of polylogarithms and regularized MZVs are derived by a single series.We also take this approach to study the extended double shuffle relations of MZVs by comparing these shuffle relations with the quasi-shuffle relations of the regularized MZVs in our previous approach of MZVs by renormalization.GUO Li1,2 & ZHANG Bin3,1Center of Mathematical Sciences,Zhejiang University,Hangzhou 310027,China 2Department of Mathematics and Computer Science,Rutgers University,Newark,NJ 07102,USA 3Yangtze Center of Mathematics,Sichuan University,Chengdu 610064,China 2010Science China Mathematics2010,53,9:4
6Host Active Defense Responses Occur within 24 Hours after Pathogen Inoculation in the Rice Blast System显示文摘Phenotypical, cytological and molecular responses of rice to the fungus Magnaporthe grisea were studied using rice cultivars and lesion mimic plants. The cultivar Katy was susceptible to several virulent M. grisea isolates, and a Sekiguchi like-lesion mimic mutant of Katy (LmmKaty) showed enhanced resistance to these isolates. Lesion mimic phenotype of LmmKaty was rapidly induced by virulent M. grisea isolates or by avirulent ones only at high levels of inoculum. Autofluorescence (a sign of an active defense response) was visible under ultraviolet light 24 h after localized inoculation in the incompatible interaction, whereas, not evident in the compatible interaction. Autofluorescence was also observed in LmmKaty 20 h after pathogen inoculation, indicating that rapid cell death is a mechanism of LmmKaty to restrict pathogen invasion. Rapid accumulations of defense related (DR) gene transcripts, phenylalanine ammonia lyase and R-glucanase, were observed beginning at 6 h and were obvious at 16 h and 24 h after inoculation in an incompatible interaction. Rapid transcript accumulations of PR-1 and chitinase had occurred by 24 h after inoculation in an incompatible interaction. Accumulations of these transcripts were delayed in the compatible interaction. These results indicate that host active defense responses occur 24 h after pathogen inoculation and that LmmKaty exhibits enhanced resistance to M. grisea. It is suggested that the autofluorescence and expression of the DR genes after heavy inoculation are important cytological and molecular markers respectively for early determination of the host response to M. grisea in the rice blast system.WANG Zhong-hua JIA Yu-lin LIN Hui Adair INTERN Barbara VALENT J.

7水生生态系统的富营养化和污染物显示文摘富营养化和长效污染物是欧洲海洋和淡水生态系统存在的主要环境问题。由于它们趋于共同产生,所以富营养化和污染物之间就有了相互作用,因而无法根据它们各自独立的作用过程来预测它们共同导致的环境影响。为了预测防治措施(改变有机质、营养物和污染物的输入)的效果,认识改变生物可利用性和污染物的迁移转化的机制是非常重要的。环境风险取决于污染物的种类形成和它们与媒介及其物质间的联系,并以此影响暴露程度。而且,风险也将取决于物质的流动性和它们在食物链中的路径。1995年,瑞典环境保护局发起了一项为期5年的研究项目'富营养化和污染物之间的相互作用(EUCON)'。前期准备的有关背景资料罗列了大量相关的问题和假设。在这些资料的基础上,项目开始启动,主要致力于海洋环境研究,重点集中在波罗的海及湖泊的富营养化和污染物(持续性有机化合物和微量金属)的相互作用上。本文总结了该项目研究的现状、前提和重点部分,强调了研究结果的应用及其意义。Jens Skei Per Larsson Rutger Rosenberg Per Jonsson Mats Olsson Dag Broman 鲁春霞 2000AMBIO-人类环境杂志2000,29,4:2
