1高光谱遥感在农作物长势监测中的应用显示文摘该研究是加拿大Saskatchewan Scott农作物轮作系统(ACS)研究的一部分。研究始于1994年,历时18a,评价9个可耕种农作物产量系统的可靠性。由3种处理水平(organic,reduced,high)和3种作物多样性水平(low,diversified annual grains,diversified annual perennials)结合而产生的9个农作物产量系统,被用于监测和评价加拿大牧场不同处理和不同作物种植轮作下可耕种农作物的产量。在2003年生长季共收集了3次叶面积指数和光谱反射率的数据:生长季前期(6月)、生长季旺盛期(7月)、生长季后期(8月)。叶面积指数是由LAI-2000植物冠层分析仪监测的,光谱测量是由覆盖了350-2500 nm波长范围共2215个波段的ADS便携式高光谱仪完成的。结果显示,光学测量可以用于监测农作物生长状况的差异。从生长季的早期到中期,光谱和叶面积指数在不同处理下有显著差异。7月中期是用遥感资料监测农作物长势的最佳季节;红光波段与近红外波段反射率的比值和基于这两个波段构造的归一化植被指数,是检测农作物长势的最佳植被指数。郑有飞 Guo X Olfert O Brandt S Thomas G Weiss R Sproule L 2007气象与环境科学2007,30,1:22
2非诺贝特治疗与2型糖尿病患者长期心血管病风险的关系显示文摘2型糖尿病患者心血管病风险高,部分原因在于高三酰甘油和低高密度脂蛋白胆固醇血症。而在他汀类药物治疗基础上,加强降低三酰甘油治疗,能否降低这种风险尚不清楚。该研究的目的是在使用他汀类药物治疗的2型糖尿病患者中,确定非诺贝特能否降低心血管病风险。刘莉 叶鹏 Elam MB Ginsberg HN Lovato LC Corson M Largay J Leiter LA Lopez C O'Connor PJ Sweeney ME Weiss D Friedewald WT Buse JB Gerstein HC Probstfield J Grimm R Ismail-Beigi F Goff DC Jr Fleg JL Rosenberg Y Byington RP ACCORDION study investigators 2017中华高血压杂志2017,25,6:7

4粗饲料种类、可代谢蛋白质浓度、碳水化合物来源对奶牛养分消化率及生产性能的影响显示文摘本试验采用中心组合试验设计对粗饲料来源、可代谢蛋白质(MP)浓度、碳水化合物种类及其互作效应对奶牛养分消化率和生产性能的影响进行了评价。所有日粮(干物质基础)均有50%由苜蓿青贮、玉米青贮构成的粗饲料、10.7%的瘤胃降解蛋白质(RDP)、4.1%~7.1%的瘤胃未降解蛋白质(RUP)、8.8%~12%的MP和22%~30%的淀粉组成。本试验共有15种日粮,试验牛分为6个区组,每个区组6头荷斯坦奶牛,分别进行3个为期21 d的试验。每期按特定顺序饲喂3种日粮后测定试验牛的产奶量、乳成分、采食量及主要营养物质消化率,还考虑了几个主要影响因素间的互作效应。结果表明:日粮淀粉浓度对奶牛养分消化率和生产性能影响较小;用苜蓿青贮代替玉米青贮可降低奶牛的氮消化率、提高中性洗涤纤维(NDF)消化率,还能增加奶牛对日粮干物质(DM)和日粮消化能(DE)摄入量,从而提高能量校正乳(ECM)、乳脂及乳蛋白产量;增加日粮MP浓度可提高奶牛对氮的消化率、ECM和乳蛋白产量,但乳蛋白含量的变化远小于NRC所推荐模型的预测值;DE浓度随淀粉浓度升高呈线性升高,但同时受粗饲料种类和MP浓度互作的影响,即日粮MP浓度较低时,DE浓度会随苜蓿青贮比例升高而降低,而日粮MP浓度较高时,DE浓度会随苜蓿青贮比例升高而升高。郑宇慧 李胜利 Weiss WP St-Pierre N R Willett L B 2018中国畜牧杂志2018,54,11:4
5Maintaining clarity:Review of maintenance therapy in nonsmall cell lung cancer显示文摘The purpose of this article is to review the role of maintenance therapy in the treatment of advanced nonsmall cell lung cancer(NSCLC). A brief overview about induction chemotherapy and its primary function in NSCLC is provided to address the basis of maintenance therapies foundation. The development of how maintenance therapy is utilized in this population is discussed and current guidelines for maintenance therapy are reviewed. Benefits and potential pitfalls of maintenance therapy are addressed, allowing a comprehensive review of the achieved clinical benefit that maintenance therapy may or may not have on NSCLC patient population. A review of current literature was conducted and a table is provided comparing the results of various maintenance therapy clinical trials. The table includes geographical location of each study, the number of patients enrolled, progression free survival and overall survival statistics, post-treatment regimens and if molecular testing was conducted. The role of molecular testing in relation to therapeutic treatment options foradvanced NSCLC patients is discussed. A treatment algorithm clearly depicts first line and second line treatment for management of NSCLC and includes molecular testing, maintenance therapy and the role clinical trials have in treatment of NSCLC. This treatment algorithm has been specifically tailored and developed to assist clinicians in the management of advanced NSCLC.Kristen R Dearing Ashish Sangal Glen J Weiss 2014World Journal of Clinical Oncology2014,5,2:3
