Objectives: The goal of this study was to assess the relations of electrocardiographic QRS duration to left ventricular(LV)measurements in individuals without heart failure(HF) or prior myocardial infarction(mi). Background: Increased electrocardiographic QRS duration(mingham Heart study participants(mean age 54 years, 57% women) without prior HF or mi. QRS duration was analyzed as a continuous variable and as categories(mi, increasing electrocardiographic QRS duration was positively related to LV mass and dimensions, and inversely associated with LV FS. Additional investigations are warranted to elucidate the mechanisms underlying the observed associations.

在建的老挝南俄3面板堆石坝坝高达两百米级,已接近世界第一高面板堆石坝-水布垭面板堆石坝.南俄3大坝堆石料模量较低,后期变形偏大,面板可能存在挤压破坏、拉裂破坏、翘曲脱空等诸多问题,危害大坝安全.设计建设期工程技术人员就面板应力变形安全、坝体-地基摩擦接触效应、面板脱空等技术问题提出了质疑.本文通过三维有限元方法结合工程实践经验对该坝结构安全以及工程措施有效性进行了细致论证,结果表明,采用了设置压性缝、提高低高程部位混凝土标号和配筋率、控制预沉降时间等措施后大坝结构安全是有保证的.本文详细阐述了南俄3大坝结构安全论证过程以及采取工程措施的必要性,研究方法和技术路线可为海外高土石坝工程的设计、计算、建设提供借鉴.

为了探究GhNAC201在棉花色素腺体发育中的作用,应用RT-PCR的方法克隆了有腺体棉花中棉所12中GhNAC201基因的编码区序列,并进行生物信息学分析。利用荧光定量PCR对有腺体和无腺体棉花材料不同生育时期、不同组织部位和不同激素处理下GhNAC201基因的表达情况进行分析。结果显示,GhNAC201编码区为948 bp,编码315个氨基酸。GhNAC201蛋白分子量为36.8 ku,理论pI 5.97,二级结构预测存在27.94%的α-螺旋、5.40%的β-转角、18.10%的延伸链和48.57%的无规则卷曲。三维结构预测表明,GhNAC201的26-190氨基酸与水稻胁迫应答NAC1蛋白序列高度匹配,模型维度为X:55.229?,Y:36.150?,Z:46.112?。GhNAC201在30-163氨基酸处存在1个nam结构域,预测有5个苏氨酸、6个丝氨酸和4个酪氨酸磷酸化位点位于nam结构域内。亚细胞定位预测GhNAC201可能位于分泌通路或除线粒体、叶绿体之外的其他亚细胞结构。不同物种中GhNAC201同源蛋白序列的相似性较高,存在5个高度保守的基序。GhNAC201与亚洲棉、雷蒙德氏棉中的同源蛋白的基序组成模式完全一致。GhNAC201基因在中棉所12各组织部位的表达量均极显著高于显性和隐性无腺体棉,且受ABA、BR、GA和MeJA诱导极显著上调表达,基因的时空表达模式与腺体密度的时空分布规律也趋于一致。综上所述,GhNAC201与棉花色素腺体发育密切相关,可能通过ABA、BR、GA和JA通路调控腺体发育或棉酚代谢。

2009年夏季在青藏高原纳木错和安多牧区对牧民帐篷内细颗粒(PM2.5)浓度和一氧化碳(CO)的含量进行了观测,以认识牧区室内空气中PM2.5和CO的污染水平、日变化特征及主要影响因素,以及不同人群在污染物中的暴露水平.观测结果表明,未安装烟囱的帐篷内PM2.5浓度和CO平均含量(体积分数)分别为1.272 mg·m-3和5.035×10-6,而安装烟囱的帐篷内二者的平均含量明显降低,仅为0.097 mg·m-3和0.089×10-6;帐篷内PM2.5和CO的日变化具有一致性,呈现出多峰值现象,这些峰值与牧民在帐篷内的活动(特别是使用牛粪炉子做饭、取暖等)有很好的对应关系,这与我国中东部农村地区室内污染物的日变化不同.妇女和儿童在帐篷内的时间最长,平均每天比其他成员多3～4 h,儿童在PM2.5和CO中的暴露水平最高,分别为0.972 mg·m-3和0.132×10-6.尽管青藏高原的室外大气非常洁净,但该地区的牧民帐篷内存在严重的空气污染,这主要是由生物质燃料(主要是牛粪)燃烧造成.

运用噬菌体表面呈现技术,从禽流感病人恢复期血中获得淋巴细胞,通过基因工程手段,构建了人源抗H5N1禽流感病毒基因工程抗体文库。用纯化的人源H5N1禽流感病毒颗粒(A/Anhui/1/2005)及重组血凝素蛋白HA(A/Vietnam/1203/2004)对Fab噬菌体抗体库进行富集筛选,成功地获得了抗禽流感病毒H5N1血凝素蛋白HA的人源单抗Fab段基因,并在大肠杆菌中获得有效表达。通过序列测定确定抗体轻重链型别,然后将阳性克隆的轻链和重链Fd段基因分别克隆入全抗体表达载体pAC-L-Fc后转染昆虫Sf9细胞,利用杆状病毒/昆虫细胞系统实现全抗体的分泌型表达。用ELISA、IFA和流式细胞术对所获人源单抗的功能特性进行鉴定。结果表明,我们获得了2株特异性针对H5N1禽流感病毒血凝素蛋白HA而与甲1型和甲3型人流感病毒无交叉反应的人源单抗(AVFluIgG01、AVFluIgG03)。微量中和试验结果表明,除A/Guangdong/1/2006外,AVFlu-IgG01能够广泛地中和HA基因进化上属于Clade2的中国南方、北方及中部地区的H5N1禽流感病毒分离株,同时还对属于CladeⅠ的越南H5N1分离株A/Vietnam/1203/2004具有中和活性;AVFluIgG03虽然不能中和A/Vietnam/1203/2004,但是对属于Clade2的所有中国H5N1分离株均具有中和作用。人源中和性抗禽流感病毒H5N1基因工程全抗体的获得不仅为高致病性禽流感病毒H5N1的预防和治疗带来了希望,同时也为其疫苗研制提供了新的思路。

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。
