With the assistance of molecular probes for reactive oxygen species, the production and localization of ROS derived from embryo, starch and aleurone layer of maize seeds with different ages were investigated under a laser scanning confocal microscope and a luminescence spectrometer.

借助活性氧发光分子探针，利用荧光光谱和激光共聚焦扫描显微技术，在不同年份的玉米种子吸胀早期，对其胚、淀粉和糊粉层细胞活性氧生成进行了定量和亚细胞定位分析。

But the role of TPO on megakaryocyte growth and development and the expression of TPO mRNA in human bone marrow are not well known.

为进一步了解TPO在巨核细胞—血小板生长发育过程中所起的作用，本文就TPO在体外培养过程中对巨核细胞生成的影响，对基质细胞以及血小板减少症患者骨髓中TPO mRNA的表达进行了研究探索。

After 24 hours of incubation,the cells became bigger,irregular and typical DCs with pseudopodium. The floating cells were separately induced to CIK cells and LAK cells. CIK cells proliferated rapidly and became a lot of large growth-colonies.

悬浮的细胞分别用于诱导生成CIK和LAK细胞，3天后CIK细胞生长迅速，出现大量的生长集落，体积明显变大呈多形性。

These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.

这些结果提示，Centrin同源基因在精子发生的不同阶段发挥不同功能，其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关，Centrin-2和-3则可能在精原细胞有丝分裂中起作用，而与精子细胞变态分化无关。

Objective 1. To investigate the expression of protein of nometastatic gene 23(nm23H1),vescular endothelial growth factor and protein of nuclear factor kappa B ( NF-kBP65) in retinoblastoma, blepharal basal cell carcinoma , blepharal squamous cell carcinoma and meibomian gland carcinoma. 2. To explore the relationship between expressions of these proteins and biological behavior of these ocular malignancies.

目的：1、检测肿瘤转移抑制基因蛋白nm23H1、血管生成因子VEGF以及细胞核因子NF-kBP65蛋白在视网膜母细胞瘤、眼睑基底细胞癌、眼睑鳞状细胞癌和睑板癌中的表达。2、探讨它们与眼部恶性肿瘤的生物学行为的关系。

Studies were conducted on cultured normal and hyperfunctioning human thyroid cells in order to compare the effects of thyrotropinon the secretion of cAMP.

以bTSH刺激体外培养的正常和甲亢甲状腺细胞，通过测定细胞生成环磷腺苷的量，探讨bTSH对两种甲状腺细胞功能的影响。

BACKGROUND: It is a debate of bone marrow mononuclear cells to promote the regeneration of infarcted myocardium.

摘要背景：关于骨髓单个核细胞促使梗死心肌再生存在很大争议，早期研究均认为非常有效，甚至可以分化为心肌细胞，但最近的文献却基本否认了这种说法，认为单个核细胞仅可以有限的促进血管生成。

The activation of endothelial cell caused by TNF-α has detrimental effects on the vasculature. TNF-α can induce the increased apoptosis of gravid trophocyte. TNF-α has been showing up-regulate the vasoconstriction factors such as endothelin and down-regulate the vascular relaxing factors such as NO on the contrary.

肿瘤坏死因子α作为炎性分子，激活血管内皮细胞、间接影响血管舒缩功能，通过各种机制诱导胎盘滋养细胞凋亡增加，增加血管收缩因子并减少血管舒张因子的生成和释放，影响与脂类代谢相关的细胞因子。

As a biomarker of vascular endothelial cells proliferation,CD105 stimulates vasculogenesis and plays key role in tumor angiogenesis.

CD105是血管内皮细胞增殖的标志之一，同时直接参与血管生成，在肿瘤血管生成过程中发挥重要作用。

After culture on coverslips and bovine cortical bone slices for 1, 3, 5, and 7 days, morphologic features, TRAP staining and bone absorptive lacunae were observed to evaluate osteoclast cells.

结果显示，当培养细胞在RANKL和M-CSF联合作用下，TRAP阳性染色的单核和多核破骨细胞可在3天内迅速形成，骨片吸收实验显示骨片上出现典型的骨吸收征象；在M-CSF(50ng/ml)协同作用下，RANKL呈剂量依赖型诱导TRAP阳性破骨细胞生成。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
