查询词典 nucleole

The cells were round before adherence,and anomalism fusiform,triangle and polygon when adhered,monocaryon,1-3 nucleole by invert phase contrast microscopy observation.Alkaline phosphatase staining and mineralized nodules staining were positive(≥98.06%).The osteoblastic activity was the highest on day 10,which was observed by MTT and morphological method.

倒置相差显微镜形态观察结果显示，未贴壁的细胞呈圆形，贴壁生长的细胞呈不规则梭形、三角形或多角形，单核，有1~3个核仁；碱性磷酸酶和钙化结节染色均呈阳性（阳性率≥98.06%）；MTT法结合形态学观察结果显示，成骨细胞培养至第10d时活性最强。

The significant changes were obseved in the morphology,size,number and the degree of development of nuclei,nucleole,mitochondrial and chloroplast of apicalmeristem cell.

在这期间茎端细胞内核仁、线粒体、叶绿体等的形态、大小、数量、发育程度等发生明显变化。

There were two or more nucleole in the nuclei of the apicalmeristem cell when the plant went into reproductive phase from vegetative phase.

植株由营养生长转入生殖生长时，茎端细胞的核内有2个或多个核仁。

METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.

摘 要］目的：探讨NFκB在大鼠肺微血管内皮细胞iNOS基因诱导表达中的作用及抗氧化剂对内皮细胞iNOS诱导表达的影响及其机制。

Results:Typical apoptotic cellular changes were found after As2O3 treatment,transmission electron microscopy showed nucleole disappeared,chromatin condensated under nucleonic membrane.

结果：经As2O3作用后VSMCs出现典型的凋亡变化，透射电镜下可见细胞核仁消失，染色质浓缩聚集于核膜下。

METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NF κ B in the cell nucleole was detected with electrophoretic mobility shift assay.

Griess法测定细胞培养上清液NO-2水平以反映NO的生成，Northern印迹分析iNOS mRNA水平，EMSA法测定细胞核内NFκB的结合活性。

Abstract］ AIM:To investigate the role of nuclear factor κB in the induction of iNOS gene by TNFα and LPS in endothelial cells and the effect of antioxidant on the induction of iNOS. METHODS:Nitrite was determined based on Griess reaction. iNOS mRNA was analyzed using Northern blot. NFκB in the cell nucleole was detected with electrophoretic mobility shift assay.RESULTS:(1)NO production and iNOS mRNA expression induced by LPS and TNFα was blocked by pyrrolidine dithiocarbamate or N-acetylcysteine.

研究表明内皮细胞激活时iNOS表达的调控主要发生在转录水平。iNOS基因的启动子区域含有多个转录因子的结合位点包括NFκB、AP-1、NF-IL6，Oct-1等［2］，而核因子κB(nuclear factor κB， NFκB)被认为在多种参与炎症反应的蛋白质因子的基因调控中担任重要角色，因而可能是内皮细胞激活的调控中一个重要转录激活因子［2，3］。

Thirdly,The nuclear chromatin of lung carcinoma cells concentrate to periphery, the electron density of cytoplasm increased, in some cells,the heterochromatin of nucleus were blurry,and the nucleole became uniform in electron density, the formatio reticularis of nucleole disappeared.

细胞核的改变：细胞核内染色质边集，基质电子密度增高。有些细胞核内异染色质分界不清，核仁呈均一电子密度，网状结构消失。

The ultrastructure:monstrous nucleus,ovious nucleole,desmosome-likestructure and surface microvilli.

电镜观察细胞核形状怪异，常染色质为主，核仁明显，细胞器少，可见高尔基器，有桥粒样结构，表面有许多绒毛状突起。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
