用于生产护肤品的阿甘油是用刺阿甘树的新鲜果实的果核通过有机棉筛挤压并过虑所提取出来的阿甘油精油，很容易被皮肤吸收，不会产生油腻感。

Among these features are: absence of the nuclear rotation and development of the centriolar complex and the initial region of the axoneme in a position directly perpendicular to the basal pole of the nucleus and presence of numerous thick anchoring fibrils connecting the proximal centriole and the proximal part of the distal centriole to the nucleus.

其特点主要是：生精过程中不发生细胞核的旋转，中心粒复合体和轴丝起始段直接发生在核的基底面垂直线上，有无数的粗的固定纤维将近端中心粒和远端中心粒的近侧部连接到细胞核上。

The haploid nucleus of a ''.

Ultrastructurally, the chalazal border of the mature egg cell demonstrates regularly discontinuous regions in which exist a great number of single or double-membrane vesicles.

卵细胞中的质体多含淀粉粒，精细胞中的质体均不含淀粉粒。DNA荧光显示，卵细胞质中具丰富的类核并可以断定环状类核为线粒体DNA。

Results HE staining showed that sulindac could inhibit the growth of tumor cells, with the morphological presentations as apoptosis and necrosis including pyknosis, karyorrhexis and chromatin crescent formation, etc. By electron microscopy, cells also had apoptotic characteristics including chromatin crescent formation and apoptotic body. Immunohistochemistry and Western-blot assay results showed that 48 hours after sulindac administration, the expression of NF-κB, bcl-2 and bax gradually decreased, while the level of bax protein gradually increased, in a dose dependence manner.

结果 苏木精－伊红染色检测结果显示舒林酸抑制肿瘤细胞生长，肿瘤细胞出现核固缩、核碎裂、染色质边集等凋亡及坏死的形态学表现；电镜下可看到染色质边集、凋亡小体；免疫组化、Western-blot结果显示舒林酸作用48 h后人胃癌SGC-7901细胞NF-κB、bcl-2表达逐渐下降，bax表达逐渐上升，具有剂量依赖性。

Methods : The molecular genetics analysis of peripheral blood karyocyte and orchi- biopsy spermatogenous cell in two patients with chromatosome caryotype abnormity in peripheral blood screened routinely

结果 核型为45，X0／46，XY，del（q11.21）；45，X0／46，XY，del（q11.23）二位患者外周血有核细胞和睾丸活检精原细胞AZF区域15个标签位点分别只扩增出SY84和SY86；SY86，其它区域位点均未检测到。

All experiment animals lived well with no death or malignant arrhythmia following cell transplantation. Frozen sections of the heart showed a few blue-stained cells under the fluoroscope in the cell transplantation group 4 weeks later. This indicated that stem cells were successfully homing. Using hematoxylin-eosin staining, homing cells were distributed over the infarct zone, with the presence of single or mass. In the model control group, no blue-stained cells were determined.

细胞移植后两组大鼠均存活良好，未出现死亡及恶性心律失常，4周后细胞移植组心脏冰冻切片荧光镜检显示心肌内有少量胞核蓝染的细胞，提示干细胞成功归巢，结合苏木精-伊红染色，归巢细胞位于心肌梗死灶周边区域，呈单个或小团聚集；而模型对照组心肌切片未见胞核蓝染的细胞。

Objective: The aims of our research are ① to filter candidate Wnt genes which are important for maintenance of normal hESCs or resulting in karyotypic change through analysis of Wnt genes of differential expression in human and mouse feeder cells and hESCs during culture of normal or abnormal karyotype hESCs.② to research the function of Wnt9a that RNAi for human Wnt9a were performed.

研究目的：对核型正常和异常的人类胚胎干细胞在体外培养过程中Wnt基因在饲养层和hESCs中的差异表达分析，分别筛选出可能促进hESCs正常增殖和引起核型发生变化的候选Wnt基因，并对其中的Wntga候选基因进行RNAi研究，了解其生理功能；在小鼠睾丸或生殖域中克隆与生精相关的新基因，并对其功能进行初步研究。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
