发帖数: 50 | 1 I want to polymerize poly(ethylene glycol) and lactide in 150 degree, stannous
octoate as catalyst. no water and high vacuum is very important.
In fact, many papers have described the polymerization: a polymerization tube
or flask connected with vacuum pump.
However, i found it's very difficult to find a suitable flask and very
difficult to keep the vacuum during the reaction.
Anyone who do this can teach me?
Thanks a lot!! |

有段时间lactid老给胖子，俺记得很久以前在stop and shop吐胖子的机器那里很ws的
拿过20多张胖子。。。 |

发帖数: 38 | 6 我娃拉了两个月断断续续，最后脱水进了急诊，住院一个星期医生也说不上来什么原因
。后来发现是对牛奶过敏，停了牛奶cheese豆奶鸡蛋之类的就好了。千万不要指望医生
，要自己找原因。八成是奶制品不消化，建议买些益生菌还有lactid的片片吃吃。拉肚
子一定要补水，买些电解质水给宝宝喝，不吃东西可以，但千万不能脱水。还有支持米
和淀粉制品这两天，不要喂奶呀什么难消化的东西。 |

nanoparticle complexes designed for gene delivery
Abstract
Poly(D,L-lactide-co-glycolide, PLGA)-chitosan nanoparticles are becoming an
increasingly common choice for the delivery of nucleic acids to cells for
various genetic manipulation techniques. These particles are biocompatible,
with tuneable size and surface properties, possessing an overall positive
