,这次埃博拉暴发的病死率在50%多一点。
一种药物把埃博拉的病死率降低了那么多,不是很不错吗?这位医生说,这13名活下来
的病人,都是在发病前5天内使用拉米夫定,而那两名不幸死亡的病人,都是在地5天和

美华不要以为自己在下面做的小动作人家洋大人不知道,只是人家没惜的管你罢了。结
果你们蹬鼻子上脸,反AA,反细分,反高中取消考试什么的,越闹越凶。太不知好歹了!
叫你们美吧!回头川大大就把你们这个微信给取缔了。看你们还折腾!
What is WeChat? Chinese-language app could be fueling Chinese-American
conservatism
A report said issues like affirmative action, unauthorized immigration and
data disaggregation received a disproportionate focus on WeChat.

w********2 发帖数: 632 | 43 NgAgo is a single-stranded DNA (ssDNA)-guided Argonaute endonuclease, an
acronym for Natronobacterium gregoryi Argonaute. NgAgo binds 5′
phosphorylated ssDNA of ~24 nucleotides (gDNA) to guide it to its target
site and will make DNA double-strand breaks at the gDNA site. Like the
CRISPR/Cas system, NgAgo was reported to be suitable for genome editing,[1]
but this has not been replicated. In contrast to Cas9, the NgAgo–gDNA
system does not require a protospacer adjacent motif (PAM).
这个好像更容易应用些? |

w********2 发帖数: 632 | 44 Anomalous nucleotide composition
HGT inferred from anomalous nucleotide composition is based on the premise
that genomes evolve to species- specific values due to replication,
transcription and trans- lation biases, variations in nucleotide and amino
acid pools, and different DNA repair preferences. Thus, if codon usage, GC
content or oligonucleotide signatures differ significantly from the mean for
a given genome, then HGT may be invoked (Dufraigne et al., 2005; Hooper and
Berg, 2002; Kanaya et... 阅读全帖 |

http://book.bionumbers.org/what-is-the-mutation-rate-during-genome-replication/
“With ≈3×109 bp in the human genome the mutation rate leads to about 10-8
mutations/bp/generation x 3×109 bp/genome ≈ 10-100 mutations per genome
per generation (BNID 110293). ”
突变会自然发生,平均一个基因组 在一个世代内,会积累10-100个突变。而Cas9脱靶
的个数我记得是每个细胞10左右,那么被编辑的露露和娜娜的基因组的实际突变率是
20-110个突变每代,并不是特别显著的增加。
那么自然人自己就有10-100个随机突变而保持健康,现在加10个;大概率的makes no
difference. |

A Chinese-born scientist was arrested on charges of trying to steal trade
secrets from companies doing research with Coca-Cola Co. , with the intent
to set up a competing venture in China and win a reward from a Chinese
government-backed program, authorities said.
In an indictment made public Thursday, You Xiaorong was accused of using her
employment at an Atlanta-based company and then at a Kingsport, Tenn.-based
company to steal trade secrets for the c... 阅读全帖 |

leaving-china-in-droves
President Donald Trump, in defending his trade war with China, has yet again
let his Twitter fingers get ahead of reality. He tweeted in late August that
“China wants to make a deal so badly. Thousands of companies are leaving
because of the Tariffs. They must stem the flow.” This supposed exodus of
foreign firms is another element informing his view that China is under
increasing economic pressure and... 阅读全帖 |

保证有足够子代试验无数可能性。复杂性在存活的新机制上叠加。
生物界的多样性就是这样来的。
人类社会的演化其实还是这个进程中的阶段。
老共治理方式和民主自由体制的竞争最后的胜出者还不知道是哪个呢。
所以福山的历史终结论成为大笑话。 |

Just as the clamor about Biogen’s seeking FDA approval for aducanumab with
one positive Phase 3 trial started to die down, a Chinese company garnered a
regulatory thumbs-up for its drug, also with one Phase 3 trial. On November
2, Shanghai Green Valley Pharmaceuticals announced that China’s National
Medical Product Administration (NMPA) had conditionally approved GV-971, aka
oligomannate, for the treatment of mild to moderate Alzheimer’s disease.
Full approval, expected to come in sp... 阅读全帖 |
