查询词典 activity stream

Coli culture . The recombinant enzyme was purified, dialysed and renatured, and exhibited arginine esterase activity, thrombin activity and fibrinogen cleaving activity without being released from the fusion partner. In animal model the recombinant protein significantly reduced rat blood fibrinogen level and inhibited experimental thrombus formation in rabbit.

国际狩猎已成为社会关注的一个热点话题，文中比较了国际狩猎与生态旅游的基本理念、活动基础、活动方式与功能、旅游者行为、态度状况等特征，探讨了国际狩猎与生态旅游的关系，从而提出国际狩猎从性质上应属于具有冒险和竞技特征的特种生态旅游活动的观点，是一种符合可持续发展的旅游模式。

Although we have not a tool to directly modulate the cellular Cdc42/Rac activity at present, nevertheless, from the abolish of BDNF-triggered attraction by either DN-Cdc42 and CA-Cdc42, we propose that an intracellular Cdc42 activity gradient may also be sufficient to determine the turning direction, say, filopodia extend preferentially at the higher Cdc42 activity side, and the growth cone turn towards this direction in the hence.

虽然我们目前还没有一个直接操纵细胞内 Cdc42或其下游分子活性的方法，但从 DN-Cdc42和 CA-Cdc42均阻断到 BDNF 和 ryanodine 的吸引作用来看，我们推测， Cdc42的活性梯度很可能也能够决定生长锥转动方向，即丝状伪足在 Cdc42活性高的一侧优先延伸，生长锥朝向该侧转动。

All is known, transportation is a activity-derived demand, there is direct or indirect touch between producing all kinds of transportation problems and daily travel behavior of residents, such as go-off, activity purpose,mode choice,and route choice. It is necessary of studying transportation system from time,space,activity and mode.

众所周知，城市交通是居民出行的派生现象，交通是一种源于活动的需求，居民日常交通行为如居民出发时间、活动目的、位置选择、交通方式选择和路径选择等，都与城市各类交通现象及问题的产生有直接或间接的联系，所以从时间、空间、活动和方式四个维度上研究交通系统是必要的。

In order to determine the immunomodulatory effect of the dietary intake of levamisole in the Chinese mitten crab, the crab were fed diets containing 0, 100, 200 and 300 mg levamisole kg1 dry diet for 7 days. The total haemocyte count, differential haemocyte count, phagocytic activity, respiratory burst, phenoloxidase activity and lysozyme activity were examined at 0, 2, 4, 6, and 8 weeks after administration of levamisole.

中文摘要：摘要：为测定在饲料中添加左旋咪唑对中华绒螯蟹的免疫调节作用，以0、100、200和300 mg · kg1干饲料的剂量将LMS添加于基础饲料中制成颗粒饲料，投喂中华绒螯蟹7 d，然后投喂不含LMS的对照组饲料。

And these two insects are sensitive to pro-toxin than toxin.2 Bt Cry1AcE toxins are composed of many peptides which have 60 kD weight, and all parts have biological activity to insect, not single part has activity.3 The mid-gut juice enzyme activity of M.

通过研究明确了以下问题： 1 Bt CrylAc毒蛋白对棉铃虫毒性较高，相比较而言对粘虫毒性较低，并且这两种昆虫对原毒素比毒素都要敏感一些。

On the other hand, 3(2)-fluoro-4-methoxyl methyl benzyl alcohol and 3(2)-fluoro-4-methyl benzyl alcohol are mixture and components of pyrethrum esters. Both of them have "mixture fluorine effect " and higher activity, lower drug resistance. As we know, the mixture benzyl alcohol containing fluorine is more easy to be synthesized than the single, so the cost of preparation is lower. We hope to apply it to molecule design of the new agriculture chemical. On the base of molecule design and structure-activity relationship research of pyrethric acid II and mixture of alcohol containing fluorine, we intend to get new pyrethrum ester that have higher activity and lower resistance.

另一方面，混合含氟对甲氧甲基苄醇和混合含氟对甲苄醇都是具有&混合氟效应&的高活性、低抗性的拟除虫菊酯醇组分，由于混合含氟醇的合成要比单一异构体的合成容易，成本较低，本文希望将其应用到新农药的分子设计中，用第二菊酸和一些含氟醇进行分子设计及进一步的构效关系的研究，筛选出一些高活性低抗性的拟除虫菊酯换代新品种。

Icariin, the main constituent of Epimedium sagittatum Maxim, and its metabolite icariside Ⅱ showed similar activity in cell proliferation. The total flavonoids from Viscum coloratum Nakai could stimulate cell proliferation and significantly promote cellular ALP activity. Daidzein and its derivatives exhibited no significant activity in cell proliferation.

结果发现：中药淫羊藿中的主要成分淫羊藿苷及其大鼠体内主要代谢物淫羊藿次苷Ⅱ具有类似的作用，可显著促进成骨样细胞的增殖；中药槲寄生总黄酮对成骨样细胞的增殖有一定的促进作用，并可显著提高细胞内ALP活性；大豆苷元及其衍生物对UMR106细胞的增殖作用不明显。

Amount of total phenolic compounds, total flavones and DPPH scavenging activity for different kinds of vinegars were compared. The results indicate that (1) DPPH scavenging activity of different kinds of vinegars has a positive correlation with amount of total phenolic compounds, total flavones, the correlation coefficients were 0.9523 and 0.8691, respectively,(2) the higher content of phenolic compounds and flavones in Zhenjiang aromatic vinegar respond for its higher scavenging activity.

对不同品种食醋总酚含量、总黄酮含量、DPPH自由基清除活性的比较分析表明：(1)不同品种食醋自由基清除活性与醋中的总酚含量、总黄酮含量存在正相关性，相关系数分别为0.9523、0.8691；(2)镇江香醋中由于总酚含量、总黄酮含量较高因而自由基清除作用较强。

MCP also had a significant antagonism to the exogenous ethylene effects on the climacteric fruits, but did't in non-climacteric fruit. Studies showed that the main mechanism of 1-MCP inhibiting ethylene synthesis in Starking apple and Feicheng peach fruit lie in the stimulation to ACS activity in ethylene system Ⅰ and the inhibition to it in system Ⅱ, and the inhibition on ACO activity rise in the whole ethylene synthesis system. But 1-MCP didn't affect the ACO and ACS activity in vitro.

研究证明1-MCP抑制红星苹果和肥城桃果实乙烯合成的主要机制在于对系统Ⅰ乙烯中ACS活性的刺激和系统Ⅱ乙烯中ACS活性的抑制，以及对整个乙烯合成过程中ACO活性升高的延缓，但对离体ACO和ACS活性并没有表现出明显的影响。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
