能发育的

Indeed, in the first weeks of their development they are practically indistinguishable.

当然，在胚胎发育的前几周里，在结构上实际不能区分出男女。

（1）Cadmium can enter embryo by permeating placenta barrier and enter brain partly and oosperm can not develop as embryo in the high dose group.（2）The decreasing of some neural transmitter and capacity of anti-oxidation are related to the content and contribution of zinc in embryoes.

（1）镉可透过胎盘屏障和部分透过血脑屏障，高镉可致受精卵不能发育为胚胎；（2）母鼠染镉可致胎鼠脑组织5-HT合成减少，抗氧化能力减弱；这些改变与锌的含量和分布改变有关。

His name was Alan. That was his name when I got him. He had cancer in the end. That, in conjunction with severe hip displacement. And he was in unbearable pain. My vet recommended, and I agreed, to euphemize him. It was humane. Which we, as a society, endeavor to be, for animals.

我养了一条小狗12年，它叫Alan，那是我得到它时它的名字，最后它得了癌症，同时还患有髋关节发育障碍，它承受着不能忍受的痛苦，我的兽医建议让它安乐死，我同意了，这是一种人道，是我们作为高级生物，能为动物所做的努力。

The plasticity of NSCs was detected by the differentiating test. HESCs were induced into dopaminergic neurons by means of adding Sonic Hedgehog Peptide and fibroblast growth factor eight (FGF8) early under the condition of mocked microenvironment and different development stage of dopaminergic neurons in vivo ,meanwhile made comparison with traditional method . The marker of dopaminergic neurons was tested by immunocytochemistry and RT-PCR, the content of dopamine and its derivation homovanillic acid were measured by HPLC-ECD.

模拟体内多巴胺神经元分化发育的不同阶段及微环境，采用早期添加音猥因子及成纤维细胞生长因子-8(FGF8)的方法，诱导hESCs定向生成多巴胺能神经元，并与传统的诱导方法相比较，免疫荧光细胞化学和RT-PCR法检测多巴胺能神经元的标志，高效液相色谱法检测诱导后细胞及细胞培养上清液中多巴胺及其代谢产物高香草酸的含量。

The hybrid between Brachymystax lenok and Hueho taimen were not a live in the past 2 years. However, the fertility and eyed rate of BH were significantly higher than that of HH and BB (P.05), while the hatching rate were significantly lower (P.05). The larvae died within 1 to 2 hours after hatching. It was observed that the tail of yolk-sac larve couldn't stretch around the yolk, and there were hyperemia in the middle and posterior segment of the tail. The reason why the hybrid between Brachymystax lenok and Hucho taimen couldn't snrvive might was the karyoplasms of the gametes from Brachymystax lerwk and Hucho taimen by distant hybridization were not compatible.

细鳞鲤×哲罗鱿的杂交经过2年多批次实验均未得到成活杂交子代，但在胚胎发育阶段BH的杂交受精率、发眼率均显著高于双亲自繁对照组(P.05)，但其孵化率显著低于双亲对照组(P.05)，BH杂交子代在破膜后1~2h内即死亡，刚破膜的仔鱼尾干中后段至尾鳍部分盘绕于卵黄囊表面不能伸展，且所有破膜仔鱼的尾干中后段均存在充血点，本研究认为，这种反交［细鳞鲑×哲罗鲑］子代不能成活的原因可能是由远缘杂交受精卵核质不相容所导致。

According to the functions of orthosis,there are four kinds:the orthosis to hold and immobilize the limb,to remedy joint contracture,to reduce spasticity and hypertonus,and to recover movement.The principles of orthosis management and common self-help aids of daily living were introduced.

中村隆一认为［1］，在脑卒中发病初期就应采用神经发育的方法治疗和指导患者自己处理日常生活活动能力，在3个月内仍不能移动以及不能自理ADL时，应改换采用矫形器、自助具和环境调整的方法，来最大限度地提高生活自理能力。

The study showed that the incidence of congenital hearing disorder in neonatal born in Tanggu district of Tianjin was nearly 0.1%. DPOAE test is simple and easy for the hearing screening in neonatus, and can detect congenital hearing disorder timely so as to interfere properly.

天津市塘沽区新生儿先天性听力障碍发病率可初步认为是0.1%；采用DPOAE能较简便地筛查新生儿的听力障碍，及早发现有听力障碍的个体，使其在语言发育的关键年龄段之前就能得到适当干预。

Total RNAs from KAx-3 cells and AK127 cells(developed for 14h) were isolated. After the reverse transcription and PCR reaction, two distinct differential fragments were acquired., fragment A was from KAx-3 cells and fragment C was from AK127 cells. After retriving and reamplifying the differentially expressed fragments, white-blue plaqueselection, the fragments were purified. Northern blot proved that fragment A was from KAx-3 cells and fragment C was from AK127 cells. The results of sequencing and researching for NCBI database have been showed: part sequence of fragment A shows 91% similarity to the gene encoding DhkA, 92% similarity to the gene encoding DhkF, 91% similarity to the gene encoding STATc, 97% similarity to the homoeobox gene encoding protein. These genes play important part in controlling cell differentiation and cell proportion in Dictyostelium discoideum.

本研究通过提取盘基网柄菌发育14小时的野生型KAx-3细胞和突变型AK127细胞的总RNA，运用mRNA差异显示法分离出了两条明显的差异表达片段，其中片段A来自野生型KAX-3细胞，片段C来自突变型Ak127细胞；并通过凝胶回收差异片段、对差异片段进行再次PCR、蓝白斑筛选克隆、提取质粒、酶切电泳纯化差异片段；接着进行Northern杂交的结果表明，片段A只与野生型KAx-3细胞的总RNA有杂交信号，片段C只与突变型AK127细胞的总RNA有杂交信号，这就排除了差异片段假阳性的可能；最后通过测序，搜索NCBI BLAST数据库发现：片段A的小部分序列与编码组氨酸激酶DhkA基因中一段序列的相似性高达91%，与编码组氨酸激酶DhkF基因中的一段序列相似性高达92%，与编码STATc蛋白基因的一段序列相似性达91%，以及与编码同源框蛋白的基因中的一段序列相似性达97%，这些基因在盘基网柄菌细胞分化和细胞比例调控过程中起着相当重要的作用，这些数据进一步说明了突变细胞不能完成发育的原因。

So researchers have been great concern. In the main wheat-growing areas such as Henan, Wen photosensitive material found great significance in the major wheat producing areas temperature changes slowly, increase much.

就是这段话：小麦属于对环境要求比较苛刻的脆弱型物种，当温光条件不能满足它们阶段发育的各种要求时，轻则表现为雄性不育，重则不能抽穗开花。

And the contradiction that should resolve these deep administrative levels, the true main body that cannot break away from Chinese stock raising -- farmer, large family and entrepreneur; cannot be broken away from the; of market economy mechanism of development cannot break away from; of structure of socioeconomy of n duality of urban and rural intersected to cannot break away from the international market in changing the competition to our country and oppressive.

而要解决这些深层次的矛盾，就不能脱离中国畜牧业的真正主体——农户、大户与企业家；不能脱离正在发育的市场经济机制；不能脱离城乡分割的二元社会经济结构；不能脱离变动中的国际市场对我国的竞争与压迫。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
