| 9 | Validation of Zebrafish (Danio rerio) Reference Genes for Quantitative Real-time RT-PCR Normalization显示文摘The normalization of quantitative real time RT-PCR (qRT-PCR) is important to obtain accurate gene expression data. The most common method for qRT-PCR normalization is to use reference, or house- keeping genes. However, there is emerging evidence that even reference genes can be regulated under different conditions, qRT-PCR has only recently been used in terms of zebrafish gene expression studies and there is no validated set of reference genes. This study characterizes the expression of nine possible reference genes during zebrafish embryonic development and in a zebrafish tissue panel. All nine reference genes exhibited variable expression. The β-actin, EF1α and Rp113α genes comprise a validated reference gene panel for zebrafish developmental time course studies, and the EF1α, Rp113α and 18S rRNA genes are more suitable as a reference gene panel for zebrafish tissue analysis. Importantly, the zebrafish GAPDH gene appears unsuitable as reference gene for both types of studies. | Rongying TANG Andrew DODD Daniel LAI Warren C. MCNABB Donald R.

| 12 | 耕作对坡耕地水土流失和冬小麦产量的影响显示文摘在模拟降雨和自然降雨条件下研究长期(6年)定位耕作措施对豫西旱区坡耕地水分保持、土壤流失以及冬小麦产量的影响。耕作措施包括少耕、免耕覆盖、深松覆盖和常规耕作。田间模拟降雨试验用来测定不同耕作措施对径流和土壤流失的影响,自然降雨小区主要用来验证模拟试验结果,同时测定不同耕作措施对冬小麦产量的影响。模拟试验结果表明:不同耕作措施下的土壤饱和导水率没有明显差异,雨前土壤含水量和降雨强度均显著影响地表径流。在试验条件下,免耕覆盖处理未产生径流和土壤流失,水土保持效果最好。与常规耕作比较,深松覆盖处理分别减少径流和土壤流失50%和90%。尽管少耕可以有效降低土壤流失,但其产生的径流量和常规耕作相近。在自然降雨条件下,免耕覆盖和深松覆盖的水土保持效果从第3年开始显著。深松覆盖在任何年型均能够显著提高冬小麦的产量。相比较常规耕作,深松覆盖平均增产9.4%。免耕覆盖除丰水年也能显著提高冬小麦产量,但增产效果不如深松覆盖显著。少耕无明显增产效果。由于产量对农民来说是评判一个耕作措施效果的重要依据,同时考虑到深松覆盖显著的水土保持效果,我们认为深松覆盖是适合当地旱作农业的一个有效耕作措施。 | 金轲 蔡典雄 吕军杰 张杰 吴会军 荣向农 Donald Gabriels Wouter Schiettecatte | 2006 | 水土保持学报2006,20,4: | 27 |

| 15 | 限制热量摄入6个月对超重者寿命指标、代谢调节及氧化应激的影响——随机对照试验AuthorAffiliations:PenningtonBiomedicalResearchCenter.LouisianaStateUniversity.BatonRouge;andGarvan.InstituteforMedicalResearch.Dadinghurst,AustraIia(DrHeilbronn).显示文摘背景:长期限制热量摄入可延长啮齿类动物的寿命。但是,尚未有研究观测长期限制人体热量是否会影响其寿命及氧化应激指标,降低代谢率。
目的:在超重但不肥胖(体重指数为25—30)的人群中研究限制热量6个月伴/不伴运动对其产生的影响。
设计、地点及参试者:于2002年3月至2004年8月在位于路易斯安娜州首府巴顿鲁治的研究中心对48名不好动的健康人进行随机对照研究。
干预:参试者在6个月内随机分为4个组:对照组(饮食可维持体重);限制热量组(限制基线所需能量的25%);限制热量+运动组(限制12.5%的热量+运动增加12.5%的能耗);极低热量饮食组(每日摄入890keal,直至体重减少15%,随后采用维持体重的饮食)。
主要观测指标:机体组成;硫酸脱氢表雄酮(dehydroepiandrostemne sulfate,DHEAS)、葡萄糖及胰岛素水平;蛋白羰基化合物;DNA损伤;24小时能耗;核心体温。
结果:6个月时各组体重变化的均值(标准误)为:对照组-1.0%(1.1%);限制热量组-10.4%(0.9%);限制热量+运动组-10.0%(0.8%);极低热量饮食组-13.9%(0.7%)。6个月时,各干预组空腹血糖水平较基线明显降低(P均〈0.01),而DHEAS和葡萄糖水平没有改变。限制热量组及限制热量+运动组核心体温有所下降(P均〈0.05)。对机体组成进行校正后发现,对照组24小时静息能耗无变化,但限制热量组(-135kcal/d[42kcal/d])、限制热量+运动组(-117kcal/d[52kcal/d])和极低热量饮食组(-125kcal/d[35kcal/d])24小时静息能耗有所下降(P均〈0.008)。上述“代谢调节”(超出预计值的-6%)与对照组相比存在显著差异(P〈0.05)。6个月时,各组蛋白羰基化合物的浓度较基线时无变化,而各干预组DNA损伤有所减少(P〈0.005)。
结论:我们的研究结果显示,长期限制热量可降低人类寿命的2种指标(即空腹胰岛素水平和体温)。此外,我们的研究结果还支持下述理论,即限制热量能降低代谢率,且超过缩小代谢面积产生的相应效应。我们尚需开展远期研究来评价限制热量能否延缓人类衰老过程。 | Leonie K. Heibronn Lilian de Jonge Madlyn I. Frisard James P. DeLany D.

| 17 | 扬子克拉通东南缘新元古代陆缘弧型TTG的厘定及其构造意义显示文摘在扬子克拉通东南缘的江山-绍兴结合带沿线多处出露新元古代深成杂岩,以往被认为是沿扬子克拉通和华夏地块碰撞缝合带侵入的板内型深成岩类。本文选择其中的浙江金华罗店中酸性深成杂岩进行了系统的岩石学、年代学和地球化学研究,提出它们属TTG岩石组合,包括英云闪长岩-奥长花岗岩-花岗闪长岩组合(T1T2G1)和二长花岗岩-花岗岩组合(G2QM)两类,普遍以明显富集Rb、Ba、K、Pb等大离子亲石元素而强烈亏损Nb、Ta、Ti、P等高场强元素为特征,δCe为弱负异常或无异常,属典型的弧岩浆岩类。T1T2G1组合富钠贫钾,εNd(t)值=+2.6^+9.4,Mg#值为41.5~63.1,推断由玄武质俯冲板片脱水部分熔融而成,并受到地幔楔橄榄岩熔体的混染。G2QM组合与T1T2G1组合地球化学特征类似,但又明显富K2O(2.75%~5.08%)、LILE和LREE,低Mg#值(27.2~52.31)和εNd(t)值(+1.7^+2.0),应是T1T2G1源区继续部分熔融的产物,可能未受到明显的地幔楔橄榄岩混染。测得花岗闪长岩(G1)锆石SHRIMP U-Pb年龄为841±10Ma,奥长花岗岩(T2)锆石LA-ICPMS U-Pb年龄为793±13Ma,前人报道之花岗岩(G2)年龄为832±44Ma,结合上述地球化学特征,说明T1T2G1和G2QM组合是由新元古代古华南洋向扬子东南缘持续俯冲形成的。综合区域地质资料及前人研究结果,提出金华罗店与诸暨璜山、绍兴平水等地的深成杂岩共同构成了扬子克拉通东南缘一条长达200km的青白口纪(930~793Ma)陆缘弧型深成杂岩带,反映迟至793Ma前仍存在强烈的洋壳俯冲,扬子克拉通尚未与华夏地块发生碰撞拼合,且T1T2G1-G2QM组合的出现指示洋壳俯冲正处于早-中期阶段。 | 姜杨 赵希林 林寿发 Donald W.DAVIS 邢光福 李龙明 段政 | 2014 | 地质学报2014,88,8: | 17 |
| 18 | Comparative effectiveness of traditional chemoembolization with or without sorafenib for hepatocellular carcinoma显示文摘AIM: To compare the overall survival (OS) and progression-free survival (PFS) with associated adverse events (AE) in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) + sorafenib vs TACE alone. METHODS: In this retrospective cohort study we collected data on all consecutive patients with a diagnosis of unresectable HCC between 2007 and 2011 who had been treated with TACE + sorafenib or TACE alone. We hypothesized that the combination therapy is superior to TACE alone in improving the survival in these patients. Data extracted included patient's demographics, etiology of liver disease, histology of HCC, stage of liver disease with respect to model of end stage liverdisease score and Child-Turcotte-Pugh (CTP) classification and Barcelona Clinic Liver Cancer (BCLC) staging for HCC. Computed tomography scan findings, alpha fetoprotein levels, number of treatments and related AE were also recorded and analyzed. RESULTS: Of the 43 patients who met inclusion criteria, 13 were treated with TACE + sorafenib and 30 with TACE alone. There was no significant difference in median survival: 20.6 mo (95%CI: 13.4-38.4) for the TACE + sorafenib and 18.3 mo (95%CI: 11.8-32.9) for the TACE alone (P = 0.72). There were also no statistically significant differences between groups in OS (HR = 0.82, 95%CI: 0.38-1.77; P = 0.61), PFS (HR = 0.93, 95%CI: 0.45-1.89; P = 0.83), and treatment-related toxicities (P = 0.554). CTP classification and BCLC staging for HCC were statistically significant (P = 0.001, P = 0.04 respectively) in predicting the survival in patients with HCC. The common AE observed were abdominal pain, nausea, vomiting and mild elevation of liver enzymes. CONCLUSION: Combination therapy with TACE + sorafenib is safe and equally effective as TACE alone in patients with unresectable HCC. CTP classification and BCLC staging were the significant predictors of survival. Future trials with large number of patients are needed to further validate this observation. | Adnan Muhammad Manish Dhamija Gitanjali Vidyarthi Donald Amodeo William Boyd Branko Miladinovic Ambuj Kumar | 2013 | World Journal of Hepatology2013,5,7: | 16 |
| 19 | Some Suggested Future Directions ofQuantitative Resource Assessments显示文摘Future quantitative assessments will be expected to estimate quantities, values, and locations of undiscovered mineral resources in a form that conveys both economic viability and uncertainty associated with the resources. Historically, declining metal prices point to the need for larger deposits over time. Sensitivity analysis demonstrates that the greatest opportunity for reducing uncertainty in assessments lies in lowering uncertainty associated with tonnage estimates. Of all errors possible in assessments, these affecting tonnage estimates are by far the most important. Selecting the correct deposit model is the most important way of controlling errors because of the dominance of tonnage-deposit models are the best known predictors of tonnage. Much of the surface is covered with apparently barren rocks and sediments in many large regions. Because many exposed mineral deposits are believed to have been found, a prime concern is the presence of possible mineralized rock under cover. Assessments of areas with resources under cover must rely on extrapolation from surrounding areas, new geologic maps of rocks under cover, or analogy with other well-explored areas that can be considered training tracts. Cover has a profound effect on uncertainty and on methods and procedures of assessments because geology is seldom known and geophysical methods typically have attenuated responses. Many earlier assessment methods were based on relationships of geochemical and geophysical variables to deposits learned from deposits exposed on the surface-these will need to be relearned based on covered deposits. Mineral-deposit models are important in quantitative resource assessments for two reasons: (1) grades and tonnages of most deposit types are significantly different, and (2) deposit types are present in different geologic settings that can be identified from geologic maps. Mineral-deposit models are the keystone in combining the diverse geoscience information on geology, mineral occurrences, geophysics, and geochemistry used in resource assessments and mineral exploration. Grade and tonnage models and development of quantitative descriptive, economic, and deposit density models will help reduce the uncertainty of these new assessments. | Singer Donald A U. S.
