| 1 | Feruloylated Arabinoxylans Are Oxidatively Cross- Linked by Extracellular Maize Peroxidase but Not by Horseradish Peroxidase显示文摘在生活玉米文化的可溶的细胞外的 arabinoxylans 的共有原子价 cross-linking,为墙界限 arabinoxylans 的 cross-linking 建模,由于到 oligoferuloyl 酉旨和醚的 feruloyl 酉旨的氧化。氧化系统负责 H2O2/peroxidase, O2/laccase,或反应的氧种类能 non-enzymically 正在行动。区分这些可能性,我们在 vivo 并且在 vitro 学习了 arabinoxylan cross-linking。在生活文化,外长,可溶,细胞外, feruloylated [pentosyl-3H ] arabinoxylans 经历了 cross-linking,突然地开始 8 ? 在再次培养以后的 d。Cross-linking 被碘化物压制, H2O2 scavenger,在内长的 H2O2 上显示依赖。然而,外长的 H2O2 没引起早熟的 cross-linking,尽管有内长的 peroxidases 的经常的存在,建议更年轻的文化包含了自然 cross-linking 禁止者。渗析的文化过滤 cross-linked [3H ] 在 vitro 的 arabinoxylans 仅当 H2O2 也被增加,显示一个 peroxidase 要求。这 cross-linking 是高度 ionic-strength-dependent。peroxidases 负责是热易变的,尽管相对热马厩 peroxidases (o-dianisidine 上的 assayed ) 也是现在。令人惊讶地,补充说甚至在热变性作用以后,山葵 peroxidase 堵住了玉米 peroxidases 的交叉结合 arabinoxylan 行动,建议山葵蛋白质是竞争底层为[3H ] 联合的 arabinoxylan。在结论,我们第一次证明在生活玉米文化的细胞外的 arabinoxylan 的 cross-linking 是 apoplastic peroxidases 的一个行动,我们报导其不平常的性质的一些。 | Sally J.

| 2 | Does aspirin or non-aspirin non-steroidal anti-inflammatory drug use prevent colorectal cancer in inflammatory bowel disease?显示文摘AIM: To determine whether aspirin or non-aspirin nonsteroidal anti-inflammatory drugs(NA-NSAIDs) prevent colorectal cancer(CRC) in patients with inflammatory bowel disease(IBD).METHODS: We performed a systematic review and meta-analysis. We searched for articles reporting the risk of CRC in patients with IBD related to aspirin or NANSAID use. Pooled odds ratios(OR) and 95%CIs were determined using a random-effects model. Publication bias was assessed using Funnel plots and Egger's test. Heterogeneity was assessed using Cochran's Q and the I2 statistic.RESULTS: Eight studies involving 14917 patients and 3 studies involving 1282 patients provided data on the risk of CRC in patients with IBD taking NA-NSAIDs and aspirin respectively. The pooled OR of developing CRC after exposure to NA-NSAIDs in patients with IBD was 0.80(95%CI: 0.39-1.21) and after exposure to aspirin it was 0.66(95%CI: 0.06-1.39). There was significant heterogeneity(I2 > 50%) between the studies. There was no change in the effect estimates on subgroup a na ly s e s o f t he po pulat io n s t udie d o r w he t he r adjustment or matching was performed.CONCLUSION: There is a lack of high quality evidence on this important clinical topic. From the available evidence NA-NSAID or aspirin use does not appear to be chemopreventative for CRC in patients with IBD. | Nick E Burr Mark A Hull Venkataraman Subramanian | 2016 | World Journal of Gastroenterology2016，22，13： | 6 |
| 3 | 青海湖老碳效应的时空变化初步研究显示文摘本文通过对青海湖周边的湖水和河流DOC、DIC浓度、^(14)C浓度,以及1F孔不同深度13个碳酸盐的^(14)C年代分析,厘清青海湖老碳效应空间分布情况。研究表明:在空间上,青海湖DIC和DOC的^(14)C的老碳各条河流分布极不均匀,南边的老碳效应明显比北边小,河流的老碳明显比湖水偏老,引起青海湖沉积物老碳效应的原因极有可能是由于北边主要河流将流域内的老碳输入湖区引起,并非由于湖水和大气的交换不畅引起的碳库效应。在时间尺度上,碳酸盐^(14)C的老碳平均值比有机碳的^(14)C老碳平均值偏老。由于入湖物质的变化,在全新世前,有机碳和碳酸盐的老碳比全新世后偏老。 | 程鹏 卢雪峰 杜花 BURR G S 宋少华 鲜锋 | 2016 | 地球环境学报2016，7，4： | 5 |
| 4 | To name or not to name? An overview of the social and ethical issues raised by removing anonymity from sperm donors显示文摘这份报纸的目的是集中于匿名的移动从精子施主提出的道德的问题。“基因真相的权利”的增加的货币在开车清楚地是可见的在西方、欧洲的国家在施主匿名上修订立法。道德的争论在“施主或父母的隐私的权利”和“未来的孩子的知道的权利”之间被极化。然而,宗教、社会、文化的态度通常在对精子捐赠的态度上有贯穿的影响,是明显的并且匿名明确地。在亚洲国家,社会、文化的遗产从西方的那些巨大地多样、不同。这评论考虑探索通知这争论的道德的问题的复杂性的研究,并且说服那个父母的决定表明到他们的孩子的施主授精起源是高度复杂的并且联系到没在政策以内被探讨把匿名从精子施主移开的社会、文化的态度的一个范围。 | Jennifer A.

| 6 | Colonic lesion characterization in inflammatory bowel disease:A systematic review and meta-analysis显示文摘AIM To perform a systematic review and meta-analysis for the diagnostic accuracy of in vivo lesion characterization in colonic inflammatory bowel disease(IBD), using optical imaging techniques, including virtual chromoendoscopy(VCE), dye-based chromoendoscopy(DBC), magnification endoscopy and confocal laser endomicroscopy(CLE). METHODS We searched Medline, Embase and the Cochrane library. We performed a bivariate meta-analysis to calculate the pooled estimate sensitivities, specificities, positive and negative likelihood ratios(+LHR,-LHR), diagnostic odds ratios(DOR), and area under the SROC curve(AUSROC) for each technology group. A subgroup analysis was performed to investigate differences in real-time nonmagnified Kudo pit patterns(with VCE and DBC) and real-time CLE.RESULTS We included 22 studies [1491 patients; 4674 polyps, of which 539(11.5%) were neoplastic]. Real-time CLE had a pooled sensitivity of 91%(95%CI: 66%-98%), specificity of 97%(95%CI: 94%-98%), and an AUSROC of 0.98(95%CI: 0.97-0.99). Magnification endoscopy had a pooled sensitivity of 90%(95%CI: 77%-96%)and specificity of 87%(95%CI: 81%-91%). VCE had a pooled sensitivity of 86%(95%CI: 62%-95%) and specificity of 87%(95%CI: 72%-95%). DBC had a pooled sensitivity of 67%(95%CI: 44%-84%) and specificity of 86%(95%CI: 72%-94%). CONCLUSION Real-time CLE is a highly accurate technology for differentiating neoplastic from non-neoplastic lesions in patients with colonic IBD. However, most CLE studies were performed by single expert users within tertiary centres, potentially confounding these results. | Richard Lord Nicholas E Burr Noor Mohammed Venkataraman Subramanian | 2018 | World Journal of Gastroenterology2018，24，10： | 2 |
