Research on the function of ANAC084 in Arabidopsis thaliana in response to the environmental stress [PDF]
, 2016 ANAC084是NAC转录因子家族的一员，其编码一个206个氨基酸的小蛋白。在拟南芥中过表达ANAC084植株出现地上部分变小，莲座叶面积变小、颜色加深，生长周期偏长的表型，但是根的发育并不受影响，进一步的研究表明过表达ANAC084会使拟南芥叶片细胞变小同时使叶片细胞数量大大减少，从而造成植株变小。但是ANAC084-RNAi和ANAC084-SRDX植株在表型上和野生型没有明显区别。通过对ANAC084Pro:gANAC084:GFP:GUS植株进行GFP扫描和GUS染色研究ANAC084的表达模式，

, 2010 窖蛋白-1(Cav-1)是胞膜窖的主要结构蛋白,可与多种信号分子相互作用,调节细胞的增殖、分化和凋亡,其异常表达与多种人体疾病的发生和发展密切相关,而在斑马鱼发育中的功能尚不很清楚。研究克隆出斑马鱼窖蛋白-1基因两个亚型的全长cDNA,与其他物种窖蛋白-1的氨基酸序列进行比较,发现该蛋白在脊椎动物中非常保守。利用逆转录多聚酶链反应检测发现,在斑马鱼多个成年组织中窖蛋白-1的两个亚型均有转录表达。利用胚胎整体原位杂交检测组织或器官特异基因的时空表达变化发现,过表达或利用Morpholino反义寡聚核苷酸(

Rare Metals, EarlyView.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

过敏性休克死亡豚鼠脏器中IgE、IL-4的表达及其法医学意义
Zhongshan Daxue xuebao. Yixue kexue ban, 2006 【目的】寻找法医学鉴定过敏性休克死亡的病理形态学诊断指标。【方法】利用组织芯片技术采用免疫组化方法（SP法）检测35只过敏性休克豚鼠（实验组28只，对照组7只）死后0、6、12、24h4个时间点的心、肝、肺、肾、脾、胃、肠、气管及扁桃体组织中的ISE及IL-4的表达情况。【结果】ISE的表达：实验组肺及气管组织呈阳性表达，并以0、6h表达最强，各时间点的表达强度有统计学意义，P〈0．01；脾组织呈弱阳性表达。各时间点的表达强度无统计学意义，P〉0．05；实验组其它脏器及对照组所有脏器均无表达。IL ...

Rare Metals, EarlyView.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.
