查询词典 ribosomes

Result: The scores of motor functions in rehabilitative training group were significantly better than those in control group on the 7th d, 21st d and 35th d (P.05). Under microscope and electron microscope the nerve-cells of cortical infarct marginal zone in rehabilitative training group showed more integrity nuclear membranes, less agglutinative chromatin, clearer structures of mitochondria and more plentiful ribosomes on rough endoplasmic reticulum compared with that in control group.

结果：在造模后第7天、21天、35天时卒中训练组大鼠的平衡木及网屏测试评分分值均优于卒中对照组(P.05)；且于光镜、电镜观察下脑皮质梗死边缘区神经细胞的核膜较卒中对照组完整、核下凝集的染色质较为稀少，线粒体结构较为清晰，粗面内质网表面核糖体更为丰富。

Ribosomes are responsible for the synthesis of polypeptide chains and its biogenesis is thus a critical process inextricably linked to cell growth and proliferation.

核糖体负责细胞内蛋白质的合成，其数量和状态跟细胞的生长密切相关。

We now know that chloramphenicol specifically affects the ribosomes of prokaryotic cells, thus inhibiting protein synthesis.

现在我们知道抗生素对原核生物细胞中的核糖体有特殊效应，从而能抑制其蛋白质的合成。

Circularization may facilitate recycling of translation factors and/or the ribosome, since ribosomes leaving the 3'end of the mRNA would be in close proximity to the 5'end for reinitiation.

环化可能有利于翻译因子和/或核糖体的循环利用，当核糖体从3'端离开后就处于5'端附近。

Ribosomes are found in large numbers in all cells, free in the cytoplasm or bound to endoplasmic reticulum.

核糖体在很多的细胞中大量的存在，在细胞质中自由存在，或与内质网结合在一起。

Electron microscope: endocytoplasmic reticulums expanding and breaking, ribosomes defluxion, lysosomes increasing, vascular endothelial cells swelling and blood vessels congestion appeared in all groups, and the mitochondria swelling is serious in the groups which pressures were more than 400 kPa.

电镜下可见内质网扩张、断裂，核糖体脱落，溶酶体增多，血管内皮细胞肿胀、血管淤血等在各压力均可发生，线粒体肿胀变形以400KPa以上压力组为明显。

Fig 1 Normal hepatocyte:glycogen particles aggregated,mitochondrialcristae clear,endoplasmic reticulum abundant ×10500;and no Ce-H2O2 precipitation ×10 500;Fig 3 1 h after Cd-injection:ER dilatant,ribosomes mostly dislodged,mitochondria slightly swollen,small amount of Ce-H2O2 precipitation

图1 正常肝细胞：糖原颗粒聚集，粗面内质网丰富，线粒体嵴清晰×10 500；图2 染镉后30分钟：肝细胞结构正常，未见Ce的沉积×10 500；图3 染镉后1小时：ER扩张，核糖体已大部脱落，线粒体轻度肿胀；可见少量

The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

结果如下：在成熟卵细胞中多聚核糖体数量不多，且细胞代谢活性较弱；初期合子内，核仁大量合成核糖体前体物质，胞质中多聚核糖体数目众多，细胞代谢活性较强；休眠期合子的核仁变小，胞质中核糖体数量急剧减少，仅有少量多聚核糖体，细胞代谢活性较弱；合子分裂前期和二细胞原胚期，核仁显著，胞质中核糖体的密度增加，出现大量多聚核糖体，细胞代谢活性较强。

The shape and structure of their ribosomes are more similar to those of eukaryotes than to bacterial ribosomes.

因为 RNA 进化速率十分缓慢，这些序列的不同被认为是最重要的鉴定依据。

In most species they are composed of roughly equal amounts of protein and ribosomal RNA , the ribosome consists of two unequally sized rounded subunits arranged on top of each other like a cottage loaf, eukaryotic cells have larger ribosomes than prokaryotic cells but the ribosomes in mitochondria and chloroplasts are about the same size as prokaryotic ribosomes.

在大多数的物种中，蛋白质的量和 rRNA 量是大体相等的。核糖体包括两个大小不同的亚单位，上部结合形成小屋状结构。真核生物细胞中的核糖体要比原核细胞的核糖体大，但是线粒体和叶绿体中的核糖体与原核细胞的核糖体大小相当。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
