The incorporation of 3H-TdR by the tumor cells was inhibited by indirubin at a concentration of less than 3×10-5M.

但在相同条件下，~(3)H-尿嘧啶核苷和~(3)H-亮氨酸的掺入没有受到明显的抑制。

Alien microbes could incorporate unusual amino acids such as isovaline and pseudoleucine, which have been found in meteorites.

外在的微生物能够合成不寻常的氨基酸，比如异缬氨酸和叔亮氨酸这些只有在陨石中出现的氨基酸。

Methods:The SD rats were each given a catheterization of jejunostomy and an inoculation of Walker-256 carcinosarcoma cells subcutaneously. Thirty-six rats were randomized into 3 groups: Group A (balance amino acid＋NS), Group B (balance amino acid ＋5-Fu), Group C (complex amino acids of arginine-enriched and leucine-enriched＋5-Fu).

SD大鼠空肠造瘘，皮下接种Walker-256癌肉瘤，36只接种成功之大鼠随机分为A组、B组(平衡氨基酸+ 5-Fu组)、C组(富含亮氨酸及精氨酸的不平衡氨基酸+ 5-Fu组)。

Leucamide A, a bioactive cyclic heptapeptide containing a unique mixed 4,2-bisheterocycle tandem pair consisting of a methyloxazole and thiazole subunit was first isolated from Australian marine sponge Leucetta microraphis.

Leucamide A是从澳大利亚海绵Leucetta microraphis中分离而得到的一种天然环肽化合物，由氨基酸及氨基酸衍生物组成：L—亮氨酸，噁唑，L-丙氨酸，甲基噁唑，噻唑，L—缬氨酸和L-脯氨酸。

Globin chain analysis proved the α chain to be abnormal The fingerprint of the abnormal α chain and the amino acid sequence of the abnormal peptide obtained indicated that the α 34 leucyl residue had been replaced by arginyl...

将异常α链经柱层析分离纯化后作指纹图，把指纹图的异常肽斑洗脱，用微量双偶合法作氨基酸顺序测定，发现异常肽斑为α34亮氨酸被精氨酸取代，由此证实此异常血红蛋白为Hb Queensα_2~(34Leu→Argβ_2。

The sample was mixed with norleucine as the internal standard, then derivatized with phenylisothiocyanate and analyzed on a Kromasil C18 column at 38 ℃, using gradient elution with detection at 254 nm.

以正亮氨酸为内标物，异硫氰酸苯酯为柱前衍生剂，用C18色谱柱在柱温38 ℃下采用二元梯度洗脱，于254 nm波长处检测。

There was no identical proteins in the database we searched, but it shared high sequence homology with PNZIP from Pharbitis nil and two other open reading frames of unknown function from Synechocystis spp and Porphyra purpurea. These together defined a new family of evolutionarily conserved leucine zipper proteins, which might play a role as a transcription factor in the regulation of gene expression.

GenBank数据库搜寻结果显示，AT103未与任何已知功能基因有同源性，但与裂叶牵牛PNZIP、集胞藻的一个ORF、紫菜的一个ORF，构成了一个在进化上非常保守的含有亮氨酸拉链结构域的新家族，极有可能是一新的核基因转录因子。

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.
