囊泡

Vesicle is the main carriers in the transportation which is delicately regulated by Rab proteins.

Rab蛋白，是一类分子量在20-25 kDa之间的GTP ，调控囊泡在细胞内各细胞器之间的运输。

So, it was demonstrated that PI3K and PtdIns-3-P had no effect on PC12 cell secretion itself, but did not exclude the possibility that they enhance cell to response to repetitive strong stimuli by their accelerating effect on vesicle endocytosis which speed the refilling of releasable vesicle.

在INS-1 细胞上的实验结果也验证了这一点，表明PI3K 和PtdIns-3-P 对细胞的分泌功能没有直接的调控作用，但是不排除它们通过促进囊泡胞吞和循环过程而增强细胞对高强度重复刺激的反应和参与突触可塑性的调节。

Results Saccate autotransplants were found in twenty-one rats , all of which were embedded in the peripheral tissues.

所有病灶都与周围组织有不同程度的粘连，病灶外观呈囊泡状。

A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

合成了带含环氧基侧链和十八烷基侧链的聚(马来酸二缩水甘油酯-co-甲基丙烯酸十八酯)，用~1H NMR对所得的共聚物进行了表征；研究了其在选择性溶剂中的自组装行为，发现P(DGMA-co-SMA)／THF／EtOH体系可以通过自组装形成囊泡形自组装体和支化的管状自组装体，P(DGMA-co-SMA)／THF／H_2O体系最初自组装形成球形自组装体，随着陈化时间的延长，球形自组装体逐渐融合成长条形自组装体和线形自组装体；探讨了自组装过程的机理，建立了可能的自组装过程模型。

In this thesis, the microfluid chip electrophoresis apparatus with laser induced fluorescence and charge-coupled device was set up in our lab and two model sample, EOS and fluorescein, were separated in a few seconds.

而建立高灵敏度、高速高效的分析方法以研究生物微环境中的超痕量物质是研究单个细胞或生物囊泡复杂的生命物质的含量、组成的关键。

These results are in accord with the working hypothesis that Rab3A is dissociated from vesicles during membrane fusion.

这些实验结果支持之前的假说，Rab3A会在membrane fusion时与囊泡分开。

The size of the microbubbles ranged from 0.1 μm to 3 μm and encapsulating effectiveness reached 25% to 42%.

研究了囊泡的包封率、形状以及尺寸大小随时间变化的情况。

Cell death is associated with the presence of numerous engorged vacuoles.

细胞死亡伴随出现大量充盈的囊泡。

The ancient rocks also contained spherical carbonaceous aggregates up to 20 mm diameter, that resemble algae or the cysts of flagellates, and delicate carbonaceous filaments up to 150μ m long.

这些古岩石也包括了球形的碳质聚集物，直径可达20mm 的类似于藻类或鞭毛虫的囊泡，以及脆弱的150微米长的碳丝纤维。

Result: In cells of weightless group and hit group,some changes were found in chloroplast grana,starch grains and vesicles in chloroplasts.

结果：发现叶绿体的基粒片层、淀粉粒及叶绿体中的囊泡等在失重组和击中组中有不同程度的变化。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
