start with? How do I know it is feasible?
any expert has suggestion? thanks in advance.

发帖数: 114 | 4 The time course of developing a new drug takes averagely 15 years from
initial sythesis to FDA approval. The pre-clinical research would take
averagely 6 and half years and clinical trials take averagely more than 7
years from phase I to phase III. And the NDA review takes another 2-3 years
at least. Well, it means that you are very lucky that your product finally
can be approved after 15 years. Millions of new chemical entities failed
during these development process. Averagely it costs more t |

precision medicine （PM） 主要的aim就是通过genomic/genetic analysis来 帮助
临床诊断， 临床治疗指南，推动 靶向治疗药物的研发。 PM有希望 完全改变临床 癌
症诊断 和 治疗的指南。
接下来的20年，NIH NCI 会往PM里面扔很多钱，估计PI们来申请 PM相关的科研，主要
的目的可能会有几个方向：
1. 哪些突变 容易引起某系癌症？ （如同bmwcar说的）但是，这个领域，已经基本上
被挖光了。。。 类似BCL-ABL 的 determinant gene 导致 的 癌症，估计已经发现的
差不多了 （BRCA，VHL，BCL-ABL, NF1, NF2,........ 一大堆）。
2. 哪些 突变/genetic background 让病人 的肿瘤 对 某些化疗药 更sensitive？ 那
些让病人的肿瘤 对 化疗药物 resistant? （目前 相同 肿瘤病人 几乎接受的是一样
的standard的化疗...）

发帖数: 104 | 10 A post-doc position in Petroleum Engineering program of Missouri University
of Science and Technology is available.
The position is open for a candidate who has strong background in polymer or
super absorbent polymer synthesis and evalulation. Our plan is to
synthesize two kinds of crosslinked polymers: the first type can be degraded
into high viscous polymer under reservoir temperature at a designed period
of time (e.g. 6 month at 45 C); and the second type can self-recrosslinked
together to fo... 阅读全帖 |

maybe you can get some idea from there.
BTW: if you got this synthesized, please be kind to give me something
for NMR study. |

BTW: I am not doing synthesis. That is just my curiousity. |

where can I find related reference talking about this?
especially flurorited polymer? |

发帖数: 175 | 15 for this synthesis, the related patent is:
Brice, T. J., and Pearlson, W. H., US Patent 2,713,593, assigned to Minnesota
Mining and Manufacturing Coop., July 1955.
I got this information from the following book:
Fluoroplastics, Volume 1, Non-Melt Processing Fluoroplastics.
ISBN:1-884207-84-7
Anothee books about Fluoropolymer may also help:Modern Fluoropolymers.

both water vapor and air but impermeable to micro-organisms (foam with sub-
micron sized voids). Iodine is added in a form of iodophor which is commonly
used in a lot of other field. Sythesis is not hard, processing is tricky I
guess. |

发帖数: 219 | 18 Thanks.
I am doing flame sythesis of carbon nanotubes, and use Cobalt as catalyst,
which is boated on the 400X400 stainless steel mesh of size 1"X1". I would
like to know what kind of carriers used for holding used meshes, where the
CNTs might be found after the test.
Thanks. |

发帖数: 166 | 19 对这个不了解,不过好象SIGGRAPH上LIWEI发了几篇用它做TEXTURE SYTHESIS,
最进还看到用这个方法来控制PBM(RIGIDBODY AND FLOCKING),挺有意思,
你想让色子摆成啥样就啥样,真正的千中高手,HEHE.
