稀释

In order to obtain versatile ulitity of host molecules, three new chiral calix [4] crown ethers containing aza, thio atoms bearing two chiral sites provided by -cysteine ester were synthesized by the condensation of calix [4] arene diacid dichloride with oligoethylene glycol bridged bis-amino acid methyl ester. All new compounds were characterized by NMR, MS and elemental analysis.

以-半胱氨酸为手性源，利用多甘醇二氯醚在碱性条件下对半胱氨酸巯基进行烷基化反应，成功地合成了多甘醇醚链桥联的半胱氨酸衍生物，醚化反应后，在高度稀释条件下与对叔丁基杯[4]芳烃二乙酰氯进行双功能基缩合反应成功地合成了新型的手性杯[4]含氮、硫杂冠醚，并利用〓H NMR、MS等谱图手段对其结构进行了表征。

A cDNA library with a tittering of 7+106 pfu/mL was constructed basing on the cotton boll shell (10 days post anthesis, dpa) RNA obtained above. The recombinant ratio was found to be ca. 90% by blue-white counting.

首次构建了构建了花后10天棉铃壳cDNA文库，未稀释文库滴度达到7×10~6，蓝白斑计数计算重组率为90％，为棉铃发育基因及其启动子的克隆研究打下了基础，目前国内外未见类似报道。

BACKGROUND: Use of the transpulmonary thermodilution techniquehas been suggested for extended hemodynamic monitoring in criticallyill patients.

Of 549 isolates, 20 isolates (about 3.6% of the total isolates) showed significant activity against P. ultimum and 15 isolates (about 2.8% of the total isolates) against R.

结果表明，对终极腐霉、立枯丝核菌的半抑制稀释倍数（ID50）在10以上的活性菌株分别为20株（占总菌株的3.6%）和15株（占总菌株的2.8%）。

Methods The present study included twelve undialyzed ESRD patients with anemia.The sera from the uremic patients were added to CFU-E and BFU-E culture in the concentrations ranging from 1.25% to 5%.In vitro CFU-E and BFU-E growth in the presence of sera from ESRD patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
