母体

Remember -- betas are like everything else with pregnancy -- they vary from mother to mother.

记住——β和怀孕其他任何事情是一样的——存在母体之间的差异。

S-1-phenylethanol was obtained in up to 19%ee in toluene at 0℃.(4)A series of C_2-symmetric chiralβ-amino alcoholsⅣ-5were synthesized in several steps from natural amino acid L-proline,and applied in the asymmetric borane reduction of prochiral ketones.

4以天然L-脯氨酸为起始原料，经过几步转化合成了以萘环为母体的C_2-对称的手性β-氨基醇Ⅳ-5，将其应用于硼烷对前手性酮的不对称还原反应中，同样，我们也观测到温度影(来源：Ac1BC论文网www.abclunwen.com)响产物构型的现象。

That is mean, weak acids tend to have lower milk/plasma concentration ratios and higher concentrations in milk, such as anticoagulants, antimetabolites, antithyroid agents, atropine, bromides, cathartics, ergot, iodides, mercurials, metronidazole, narcotics, and radioactive agents.

乳汁中药物浓度大部分较母体循环中药物浓度低，例如哺乳期妇女服用红霉素、磺胺类、异烟肼、甲硝唑，乳汁中各药物浓度约为血清中该药物浓度的50%，而青霉素、头孢菌素在乳汁中的浓度仅不足血清中该药物浓度25%。

CIRe is well-positioned in its local,"home" markets, and is confident to maintain its leading position at acceptable terms and conditions.

Results The results showed that EM depurating lake water didn't effect on weight gain of parental rats,litter weight,live ra...

结论在37.5~150 g.kg-1剂量范围，应用EM净化8个月的湖水对大鼠无母体毒性、胚胎毒性和致畸作用。

The most stable geometry of C78O is the 73, 78-C78O molecule with an epoxide structure.

讨论了电子跃迁性质和73，78-C78O电子光谱的长波吸收峰与母体相比发生蓝移的原因。

TOAB (tetra-n-octyl-ammonium bromide) serves as a catalyst initiating the reaction between dodecanethiol and Cux(x-2). When it is absent, nanoparticles were not formed and white floccules were observed in the bottom of toluene phase .

四丁基溴化铵起到催化剂的作用，在它存在的时候，十二烷基硫醇和铜母体的氧化还原反应优先发生。

The proportions of amino acids are also different; for example there is normally a much higher concentration of glutamic acid in foetal blood in comparison with the blood of the dam.

并且氨基酸的组成也是不相同的，例如胎儿血液中的谷氨酸的含量远远高于母体血液中的。

Foetal boood always contains approximately three times as much free amino acids as the dam's blood.

胎儿血液中含有大约于母体3倍的游离氨基酸。

These findings suggest that maternal folate status is an important determinant of infant birth weight.

这些研究发现，母体的叶酸水平是新生儿出生时体重的重要决定因素。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
