大鼠腹侧中脑多巴胺能前体细胞可在体外大量诱导分化成TH阳性的主要源自A10区的多巴胺能神经元。

Rat ventral mesencephalic precursors can be induced to differentiate into plenty of tyrosine hydroxylase-positive DNs, mainly originating in A10 regions.

大鼠腹侧中脑多巴胺能前体细胞可在体外大量诱导分化成酪氨酸羟化酶阳性的主要源自中脑腹侧被盖区(A10)的多巴胺能神经元。

The enlarged showy calyx-lobes in Mussaenda are good examples. The calyx-lobes, so called calycophylls, are mostly leaf-shaped, but have bright color, papillate epidermis, and loose mesophylls, features generally only found in petals. In higher eudicots, floral organs are typically arranged in four different whorls, namely sepals, petals, stamens and carpels.

自然界中有钗h植物以一整个花序替代一朵花作为传粉的单位，而在这样的花序中常常会有某些构造花瓣化来替代原来花瓣的弁遄C玉叶金花是一个非常有趣的例子，这一属的植物常具有膨大的花萼裂片，其形状类似叶子但多具有鲜艳色彩，且细胞形态及细胞排列均相当类似於花瓣，在弁鄐W一般均认为与花瓣无异。

Analysis of mitochondrial DNA composition of the panda-rabit cloned embryos found that mitochondria from both panda somatic cells and rabbit ooplasm co-existed in early blastocyst, but mitochondria from rabbit ooplasm decreased and those from panda donor cells dominated in early fetuses after implantation.

结果显示，应用卵裂球电融合方法可以制作一系列的多倍体胚胎；小鼠囊胚的形成与胚胎中的细胞数目无直接关系，卵裂球的电融合和染色体数目的增加不会改变胚胎的发育进程；而胚胎细胞中的核／质比可能是控制胚胎囊胚化的一个重要因素。

The significant differences existed in lower epidermis among materials:in 2 splitting-resistant cultivars,their anticlinal walls had clearly sinuous ridges and the periclinal walls had equal thick ornamentations of cuticles; the defensive cells were rounded cuticles of projected ridges,and epidermal cells were covered with dense powder.

材料间下表皮微形态存在较显著的差别：耐裂材料的垂周壁上有明显的波状嵴，平周壁上有加厚的条纹状角质层纹饰，保卫细胞四周角质层褶皱较多、起伏较大，表皮细胞上覆盖有大量的粉状或颗粒状蜡质。

Methods: We used a 5075 gene cDNA microarray to examine gene expression in peripheral blood mononuclear cells from two type 2 diabetes patients with distal symmetric polyneuropathy, two type 2 diabetes patients without distal symmetric polyneuro...

采用包含5075个功能已知人类基因的cDNA芯片检测2名2型糖尿病并发远端对称性多神经病变患者，2名2型糖尿病不伴远端对称性多神经病变患者以及2名年龄和性别匹配的正常个体外周血单个核细胞基因表达谱。

The actin cytoskeleton, a dynamic network of intracellular proteinaceous structural elements participates in many physiological activities in plant cell.

植物细胞中的微丝骨架，是细胞内的一个由蛋白质构成的动态网络结构，参与胞内诸多的重要的生理活动。

Topotecan is an effective agent for SCLC when used as monotherapy or in combined treatment, but myelosuppression such as leucopenia and thrombopenia was relatively severe. Although it has been recommended as a second-line agent for recurrence of sensitive SCLC, more clinical trials are needed to define its role in first-line treatment.

拓扑替康治疗小细胞肺癌有确切临床疗效，无论是单药还是与其他药物的联合用药均具有与当前一线经典方案相当的疗效，但具有相对高的致白细胞和血小板下降的骨髓毒性，已被认为是治疗化疗敏感的小细胞肺癌患者复发的二线推荐药物，但是作为一线用药仍然需要更多的实践来证实。

The point mutations of the 12th coden of ras gene and p53 E5 and E7 gene were studied in 40 cases w ith laryngeal squamous cell carcinomas by PCR-SSCP(polymerase chain reaction-s ingle stranded conformational polymorphism).

应用多聚酶链反应-单链构像多态性分析方法分析40例喉鳞状细胞癌H-ras，K-ras，和N-ras基因的第12密码子，p53 基因第5，7外显子中点突变的情况。

It was confirmed that facultative apomixes is existed in coffee species based on emasculating treatment, cyto-genetic observe and SSR marker detection.

细胞遗传学观察发现咖啡四倍体类型材料(2n=4x=44)的多胚和多胚苗中含有天然的单倍体胚和单倍体小苗(2n=2X=22)；去雄处理后，可见子房膨大，其中5份材料获得了果实和种子，初步说明无融合生殖现象的存在；对小粒种品种间杂交F1代个体的SSR分析，发现多胚苗中存在与母本图谱相同且不携带父本特异带的后代以及携带双亲特异带的有性后代，表明子代有仅来自母本的无融合生殖个体分离出来。 3 建立了咖啡无融合生殖的分子鉴别方法。

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。
