This result indicated that the best way to purify soybean agglutinin was GalNac-epoxy-Sepharose 6B.

这一结果表明大豆凝集素最理想的纯化方法是N-乙酰基-D-半乳糖胺-expoxy-sepharose 6B亲和层析体系。

But if we start shifting back to non-Bt cotton, I promise you, the tobacco budworm will come back, and we don't want to be making foliar applications for resistant tobacco budworms, in addition to treating tarnished plant bugs.

像牧草盲蝽一样，叶螨对用来控制它们的杀虫剂正在产生抗性。过去15年以来，我们已经基本上翻倍了百治磷的使用率，乙酰甲胺磷的使用率则增至三倍。

The purified active substance is composed of alternating disaccharide units (glucuronic acid and N-acetyl galactosamine).

单纯的活性药物成分由若干交互的二糖单元（葡萄糖醛酸和N－乙酰－半乳糖胺）连结而成。

In this report, the 59Tc labelling of Annexin V fragment modified with HYNIC (HYNIC-Anx13) using Tricine, EDDA or EDDA/Tricine as coligands was described. The effect of various factors on 99Tc labelling was investigated. Biodistribution studies in normal mice and gamma imaging of apoptosis in rats induced by cyclophosphamide were performed.

为探讨99Tc标记的HYNIC-Anx13用于细胞凋亡显像的可能性，分别以N-［三甲基］甘氨酸，乙二胺－N，N'-二乙酸和EDDA/Tricine为协同配体，对经6-肼基烟酰基修饰的膜联蛋白V片段(HYNIC-Anx13)的99Tc标记条件和主要影响因素进行了研究，并完成了HYNIC-Anx13的99Tc标记物在正常小鼠体内的生物分布和大鼠细胞凋亡模型的显像实验。

The results show that these derivatives can be obtained in the yield of over 90％ in the presence of DMF when using ethyl acetate as a catalyst.

结果表明，以N，N-二甲基甲酰胺为溶剂，以乙酸乙酯为催化剂的合成路线，均可以以90％以上的得率合成出上述化合物。

Examples of suitable polar volatile liquid are amines ethers especially lower alkyl ethers organic acids esters ketones glycols alcohols amides ureas sulphoxides sulphones and water.

合适的极性挥发性液体的例子有胺，醚，尤其是低级烷基醚，有机酸，酯类，酮类，乙二醇，乙醇，酰胺，尿素，sulphoxides，砜和水。

Occasionally, we observed the four-component iodoamination of 1, 2-allenyl selenides with I〓 in MeCN at room temperature.

我们还发现1，2-联烯基硒醚在无水乙腈中可以与碘发生碘胺化反应生成酰胺，在此反应中溶剂乙腈参与了反应。

The invention adopts halogen acetylized crosslinked polystyrene resin and hydroxybenzyl alcohol as the raw material, and the solid phase synthesis carrier with hydroxymethyl as the active group is synthesized through the joint catalysis of N, N-dimethyl formamide used as the reaction solvent, inorganic base and phase-transfer catalyst.

本发明采用卤乙酰化交联聚苯乙烯树脂和对羟基苯甲醇为原料，在以N，N-二甲基甲酰胺为反应溶剂、无机碱及相转移催化剂的共同催化下合成了一种以羟甲基为活性基团的固相合成载体。

Ethambutol is a first-line drug used for antituberculosis therapy. It is often used in combination with isoniazid, rifampin, pyrazinamide, and streptomycin. The action of EMB in antituberculosis mechanism is the destruction of cell wall of tubercle bacilli via binding the target molecule -- arabinosyl transferases. These enzymes are involved in the polymerization of the cell wall arabinan. Inhibition of arabinan synthesis by EMB results in the accumulation of mycolic acids, leading to cell death.The EMB-resistance of MTB is involved with the mutation of emb operon or the over expression of emb operon.

乙胺丁醇是和异烟肼、利福平、链霉素、吡嗪酰胺联合治疗结核病的一线抗结核药物，EMB对结核分枝杆菌的作用机制与分枝杆菌胞壁结构破坏有关，主要作用于靶分子阿拉伯糖基转移酶，抑制了阿拉伯糖基聚合入阿拉伯半乳聚糖，从而影响细胞壁分枝菌酸-阿拉伯半乳聚糖-肽聚糖复合物的形成，导致菌细胞的死亡。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
