New FDA draft guidance calls for more patients and lengthier trials for companies with certain safety issues, but the rules are no different from what is expected in drug development for other chronic conditions, the agency has said.

FDA新的指导草案要求涉及安全性问题的公司加大病例数，延长试验时间，但FDA声称这些规定与其他慢性病治疗药物研发的要求是一致的。

Cell embryos were cultured in vitro, then viability was observed. The results showed the fertilizing rate in vitro of the group for GV oocytes with cumulus cells after maturating which were conserved at 10℃ for 24 h, 15℃ for 14 h, 20℃ for 8 h and 25℃ for 4 h was 14%, 9%, 10% and 10% respectively, and with the advance of storage temperature and extension of storage time, the rate of 2-cell after maturating-fertilizating of the GV oocytes decreased significantly.

其结果，在10℃下保存24h、15℃下保存14h、20℃下保存8h和25℃下保存4h后，其体内附有卵丘细胞的GV卵的体外成熟－体外受精后的2细胞率分别为14%、9%、10%和10%，随着保存温度的提高和保存时间的延长，带有颗粒细胞GV期卵的比率明显降低，同时其GV期卵经体外成熟及体外受精后的2细胞率明显降低。

Therefore, it is possible that liposome drug delivery system raised the DXR's inhibition effect of metastasizing of carcinoma.

因此，脂质体形成了DXR的体内贮库，延缓了DXR在中央室的消除以及从中央室向周边室的分布，延长了DXR在血液循环系统中的运行时间。

In fact, prolonged boiling wastes fuel and increases the concentration of nitrates, which are dangerous for very young babies.

事实上，延长沸腾时间消耗燃料并且增加硝酸盐浓度，对于幼小的婴孩是很危险的。

The result shows that the recycling effluent upgrades significantly the removal for BOD_5,COD,SS,and NH~+_4-N,and BOD_5 removal rate meets the Monod equation;most part of NH~+_4-N is nitrified and the removal rate of NH~+_4-N is linear with the surface loading rate.Along with the nitrification,alk...

结果表明：循环出水显著提高了对BOD5、COD、SS和NH+4-N的去除率，且对BOD5的去除满足Monod方程；大部分NH+4-N的去除率与其表4-N被硝化，对NH+面负荷率呈线性关系；随着硝化反应的进行，碱度减少，pH值不断降低；循环出水可引入部分氧气，延长了污染物和附着于植物根系微生物的接触时间，提高了对污染物的去除率。

Excellement, denoted as Z media, provides cleaner oil, longer element life and less downtime, and outlasts, outperforms, and excels in every measurable benchmark.

Excellement ，标注为z介质，提供清洁的油，延长使用命和减少停机时间，在每一个可衡量的基准。

Results In contrast with enzymatic dissociation, the method of mechanical dissociation, breaking up great neurospheres into small spheres with gradually reduced pipette, had advantages of raising cell viability and shortening cell doubling time (P.05). After NSCs being cultured long term in vitro, the number of neurons generated decreased with passaging, whereas the number of astrocytes increased.

体外长期培养条件下，随着培养时间的延长，NSCs分化为神经元的比例逐渐降低，星形胶质细胞的比例逐渐增高；在4~12代NSCs分化为神经元的能力表现出下降的趋势，但仍较为稳定；12代后，神经元的分化比例迅速下降，星形胶质细胞的比例迅速上升。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
