1污泥用于林地15年后养分和重金属在土壤中分布的研究显示文摘对极粗质地的森林土壤一次施用500t/hm^2干污泥15年后的土壤剖面样品,分析了pH值、ECE、全N、P、K、S、Ca、Mg、Cd、Cu、Ni、Pb和Zn等,并同对照土进行比较。表层(0~17cm)中全N、P、S、CEC、Cd、Cu、Ni、Pb和Zn的含量明显高于对照区;由于这种风化不完全的土壤含K、Mg、Ca较丰富,处理区与对照区差异不大;土壤pH值处理区要低;Mg移到较深层次;Ni和Zn稍有移动;Pb、Cd、Cu、移至17~27cm,但未再向下层移动。薛栋森 Rob Harrison Chuck Henry 1992西北农业大学学报1992,20,3:10
2A Review on the 3D Printing of Functional Structures for Medical Phantoms and Regenerated Tissue and Organ Applications显示文摘医学模型或模具已广泛应用于医学培训和医患互动领域,同时也日益应用于手术规划、医学计算模型、算法核实和验证以及医疗器械的开发等方面。这种新应用需要高保真度、患者特异性及模拟组织结构的医学模具,其不仅能够模拟人体器官的几何结构,而且还具有器官的功能。随着三维(3D)打印和3D生物打印技术的快速发展,许多研究人员已经开始使用增材制造技术来生产具有多种功能的医学模具。本文综述了3D打印和3D生物打印技术在制作功能性医学模具和生物结构方面的应用。特别讨论了3D打印功能性医学模具(即组织模拟医学模具、放射性医学模具和生理医学模具)及被用于再生组织和器官的3D生物打印模具的制备(即混合模式支架材料、可转换支架和集成传感器)工艺、发展现状以及未来发展趋势。Kan Wang Chia-Che Ho Chuck Zhang Ben Wang 2017Engineering2017,3,5:9
3Molecular evolution of the rice miR395 gene family显示文摘MicroRNAs (miRNAs) are 20-22 nucleotide non-coding RNAs that play important roles in plant and animal development. They are usually processed from larger precursors that can form stem-loop structures. Among 20 miRNA families that are conserved between Arabidopsis and rice, the rice miR395 gene family was unique because it was organized into compact clusters that could be transcribed as one single transcript. We show here that in fact this family had four clusters of total 24 genes. Three of these clusters were segmental duplications. They contained miR395 genes of both 120 bp and 66 bp long. However, only the latter was repeatedly duplicated. The fourth cluster contained miR395 genes of two different sizes that could be the consequences of intergenic recombination of genes from the first three clusters. On each cluster, both 1-duplication and 2-duplication histories were observed based on the sequence similarity between miR395 genes, some of which were nearly identical suggesting a recent origin. This was supported by a miR395 locus survey among several species of the genus Oryza, where two clusters were only found in species with an AA genome, the genome of the cultivated rice. A comparative study of the genomic organization of Medicago truncatula miR395 gene family showed significant expansion of intergenic spaces indicating that the originally clustered genes were drifting away from each other. The diverse genomic organizations of a conserved microRNA gene family in different plant genomes indicated that this important negative gene regulation system has undergone dramatic tune-ups in plant genomes.Sreelatha GUDDETI De Chun ZHANG Ai Li LI Chuck H.

5Inhibition of apoptosis by oncogenic hepatitis B virus X protein: Implications for the treatment of hepatocellular carcinoma显示文摘Hepatitis B virus X protein(HBx) plays an important role in the development of hepatocellular carcinoma(HCC). In addition, hepatoma upregulated protein(HURP) is a cellular oncogene that is upregulated in a majority of HCC cases. We highlight here recent findings demonstrating a link between HBx, HURP and anti-apoptosis effects observed in cisplatin-treated HCC cells. We observed that Hep3B cells overexpressing HBx display increased HURP mRNA and protein levels, and show resistance to cisplatin-induced apoptosis. Knockdown of HURP in HBx-expressing cells reverses this effect, and sensitizes cells to cisplatin. The anti-apoptotic effect of HBx requires activation of the p38/MAPK pathway as well as expression of SATB1, survivin and HURP. Furthermore, silencing of HURP using short-hairpin RNA promotes accumulation of p53 and reduces cell proliferation in SK-Hep-1 cells(p53^(+/–)), whereas these effects are not observed in p53-mutant Mahlavu cells. Similarly, HURP silencing does not affect the proliferation of H1299 lung carcinoma cells or Hep3 B HCC cells which lack p53. Silencing of HURP sensitizes SK-Hep-1 cells to cisplatin. While HURP overexpression promotes p53 ubiquitination and degradation by the proteasome, HURP silencing reverses these effects. Inoculation of SK-Hep-1 cancer cells in which HURP has been silenced produces smaller tumors than control in nude mice. Besides, gankyrin, a positive regulator of the E3 ubiquitin ligase MDM2, is upregulated following HURP expression, and silencing of gankyrin reduces HURP-mediated downregulation of p53. In addition, we observed a positive correlation between HURP and gankyrin protein levels in HCC patients(r^2 = 0.778; n = 9). These findings suggest a role for the viral protein HBx and the host protein HURP in preventing p53-mediated apoptosis during cancer progression and establishment of chemoresistance.Chuck C K Chao 2016World Journal of Hepatology2016,8,25:5

9从中式英语到地道的英语(英文)显示文摘在当今的中国,使用'中国式英语'是一种十分普遍的现象,本文试图从一个外籍专家的角度对此现象的产生根源进行理论上的探讨,其中有母语的干扰,搭配的不当,文化的交叉,翻译的错误,过时的表达,习惯的模仿,甚至有词典的失误,教材的误导,还有美国式和英国式英语的差别等。作者还用大量的实践例子来加以充分说明。本文的目的在于使中国的英语教师认识到此问题的严重性,并在其教学过程中努力克服,从而使他们的学生能够学会标准的'地道英语'。Chuck Allanson 周崇明 2004Chinese Journal of Applied Linguistics2004,27,6:2
10私募股权投资在美国页岩气基础设施建设中的新角色显示文摘页岩气已经成为美国能源结构中的重要组成部分。在不断发展的美国页岩气领域,高峰产量与气体收集和处理设施、管道的计划能力之间存在巨大差距,凸显了额外投资的必要性。页岩气资源的大规模开发已经吸引了许多建设中游设施的投资,但投资来源非常分散,基础设施建设缺乏统一的规划和协调。三类主要的基础设施建设投资来源是独立勘探开发公司、中游的业主有限合伙企业(MLP)和私募股权基金支持的中游公司。当前,由私募股权基金支持的业主有限合伙企业正成为基础设施投资的中坚。Chuck Chakravarthy Rachael Goydan Meltem Demirors 黄佳音 2010国际石油经济2010,18,8:2
11电源电子技术在降低能耗中的角色显示文摘全世界对能源消耗的关注日渐增加。作为减少能源消耗的两种方式,能源节省需要个人的自觉性加社会决策,而能效提升就纯粹是一个技术问题。美国使用的电能中的3%在电子电源转换过程中耗散为热量。因此电源电子产业,包括半导体公司、电源公司和终端产品制造商正在努力使这些损耗减少一半。他们所采用的方式就是提升大批量消费电子产品中的电源转换效率并降低待机能耗。Chuck Mullett Dhaval Dalal 2008今日电子2008,,4:2
