I have said in my second response that no work has been done in vivo yet.
Actually, not only H2SO2 and NaOH but also pure water can kill bacterial. If
you don't believe, you can put some bacterial in autoclaved H2O (without
any other chemicals) to see whether the germ will grow. But as a scientist,
we should know what's underlying.
I agree with you that the specificity will determine whether the protein
will be useful or not. The determinants for a protein enzyme to be a good
antibacterial are t... 阅读全帖

其实试验上最近突破挺大的。最近有两篇文章几乎同时出来(PNAS; Naure
Communication), 关于in vitro formin如何感应力并调控actin生长速度。不知道你看
到没有。in vivo 也有很大进展。Sheetz组现在能够直接in vivo 测量 focal
adhesion protein的end-to-end distance. 其中talin的工作去年已经发表在PLoS
Biology上。 今年会有一系列别的蛋白的结果出来。会非常有趣。
in vitro adhesion protein如何感受机械力,如何unfold, 如何因此和别的signaling
protein相互作用把机械力信息转化成生化反应信号传递,今年会有一系列工作出来,
包括talin-vinculin, alpha-actenin - vinculin, 等。
上面这些全部都是直接单分子测量,和模拟无关。 我觉得你说得挺对的。这个方向似
乎很快就会有很大突破。

简单说吧,结构对做新药,尤其是discovery阶段的candidate非常有用,做药的都希望
有尽量多的结构信息。但结构即不是必要条件也不是充分条件。至于离最后做出新药还
有十万八千里。说什么解出结构就看到新药的曙光,征服什么什么疾病,那是纯粹胡扯。
就结构本身,当然in vivo的结构是最有用,但是目前没有有效的手段得到对做新药有
用的结构。那么解晶体还是目前最有效的也是最成功的手段。所以一说到解结构,那么
大家首先默认的就是X光衍射解晶体。至于晶体状态和in vivo状态下结构的差异,确实
是个conern,但是在很多晶体结构还渴望不可及的情况下,基本上还不需要太concern
这个问题。其他手段也有NMR,包括这个电镜,有不错的例子,也有他们的优势,但总
体上和晶体结构提供的information差远了。至于这个4.5A的电镜结构,对做药基本上
没用。

来自主题: Biology版 - CD4+ T细胞分化和相关动物模型
我觉得应该更倾向于相信in vivo的数据,既然KO小鼠不发病,且CNS里CD4+细胞绝对数
降低,那么这就是一个promising的现象,可以围绕这个来开展实验。
至于体外分化的结果, 我觉得除非敲掉的是t-bet,gata3这种基因,否则很难有很显
著的差异,我认识一个人做Th17,他体外分化后测Il17,有时候好一点大概是30% vs
40%, 有时候差一点就基本没差别了,最后还是照样发NI,关键是in vivo的差异很明
显。
仅供参考。
另外,就是感觉这几年这种题材的文章越来越难发NI这种级别的杂志了,基本没有

来自主题: Biology版 - 关于药物化合物筛选
楼主说的对,现在的化合物库和化合物设计、合成、in vitro筛选等都不是瓶颈,in
vitro筛选的效力惊人,只要有足够的化合物,in vitro活性都可以得到。
真正的瓶颈在in vivo筛选,这里面的最大问题的动物模型,现在最常用的是大鼠和小
鼠。这些动物in vivo和人类的相关性、预测性等完全没有办法,动物模型本身的病理
状态和人疾病的相关性等。如果哪一天猴子模型可以很普遍的应用,可能这些预测性和
相关性会好很多。
《PNAS》最近提到的生命科学类11月最受关注的十篇论文中提到小鼠模型须小心使用,http://www.biomart.cn/news/103/129225.htm
小鼠被广泛用于模拟人类代谢、疾病和药物应答,是医学研究中的一个基本工具。然而
斯坦福大学的研究指出,人类和小鼠的基因表达存在着惊人的差异,不论是蛋白编码基
因还是非编码基因。这项研究发表在十一月十七日的美国国家科学院院刊PNAS杂志上。
相信在未来的不久对大鼠基因表达也会有类似的研究,这样应该可以比较好的解释为什

摘要
1970年代早期,多数中国科学家,在文化大革命中努力生存而无机会开展研究。两位年
轻的研究者屠呦呦和张亭栋,分别在发现抗疟新药青蒿素和揭示砒霜化学成分三氧化二
砷对白血病的治疗作用的过程中起了关键作用。回顾四十年前开始的历程,不乏曲折和
反讽。青蒿素工作源于中国帮助越南抵抗美国,三氧化二砷源于观察、验证和改进乡村
中医的实践。虽然他们的药物挽救了世界上很多生命,两位研究者迄今未获国内外充分
肯定,屠呦呦有争议、张亭栋基本默默无闻。相关的文献埋没于冷僻的杂志和一般不易
看到的内部会议资料。基于原始中文论文、文件和采访,我们在此呈现这些发现的历史
概貌。没有逃脱我们的注意,在古代和近现代中文文献及医疗实践中,可能还有尚待重
新发现的珍宝。

在中国使用了上千年的传统药物,能否改善现代人类的健康?在中国,有些人不认为这

看到最近那个亲生母亲生下孩子基因和母亲体细胞不匹配的新闻了吗?
异元细胞在子宫里融合, 一个人的不同器官有不同遗传信息,现在不太清楚这个比例
占多少, 如果不是小概率事件, 对实验结果的影响应该会很大,
当然,我之前的研究对象是植物, 不太清楚在植物界中是否有相似的情况
我是转行一族, 之前做生化实验还可以, 但in vivo的结果差异太大, 而且不只是我
一个人, 而是整个群体, 经过2~3年的经历, 使我认识到凭自己的微薄之力,只能苟
延残喘, 不弄虚作假, 很难生存, 高质量的研究没有in vivo怎么能行, 这么多基
因, 找到一个好基因除了碰运气, 比海底捞针还难, 我可以选择继续前行, 但亡羊
补牢,为时未晚, 苦海无边,回头是岸; 与其回国做一个正教授, 整体顶着卖白粉
的压力, 干着卖白菜的买卖, 我感觉凭我的能力,找对方向应该比这个更强。
希望各位生物里的有能力的同学们能走出一条属于自己的创新之路,加油!

总结2016.10.13 【记录历史】谁重复验证了NgAgo?
引子
我们生活在一个幸运的时代,我们生活在一个变化的时代。
历史就在我们每一天不经意的时候悄悄地留了下来。
世界各地的2016年都不同寻常,记录一下有些瞬间即逝的印记。
2016年生物领域的 {韩春雨事件} 已经进行了5个多月了。
由于无法被同行重复,韩春雨的NgAgo基因编辑工具,已经被世界各地做基因
编辑的科研人员们放弃了。同行们会接着使用CRISPR这个很可靠的基因编辑
工具。
虽然基因编辑行业现在已经放弃了韩春雨的NgAgo,韩春雨还是对世界科研界
造成了不小的影响。
那么,这个事件的影响有多大呢?
据Addgene 2016年8月份统计,已有近30个国家的大约400个实验室从
Addgene拿到了韩春雨的NgAgo 质粒。而中国的实验室,很多是直接从韩春雨
那里拿到质粒的。另外相当一部分的实验室,是自己克隆或合成NgAgo的。这

A postdoctoral position is available to work on drug discovery in the
Department of Chemistry and Biochemistry and Milwaukee Institute of Drug
Discovery at the University of Wisconsin-Milwaukee. The research will focus
on synthesizing small molecules and studying their biological properties,
including testing anticancer activity both in vitro and in vivo, figuring
out the mechanism of function (such as interactions with DNA, DNA damage,
cell damage, PK and stability study, etc.). The lab has acc... 阅读全帖

美国当地时间11月17日凌晨0点45分,在刚刚结束的3GPP RAN1 87次会议的5G信道编码
方案讨论中,经过艰苦卓绝的努力和万分残酷的竞争,以中国华为公司主推的Polar
Code(极化码)方案,成为5G控制信道eMBB场景编码方案。
编者按
“华为极化码事件”内幕:
极化码获得的并非之前大肆炒作的“短码”。
极化码打败的对手并不是LDPC,而是在控制信道上取代4G现有技术TBCC。
若非极化码最终靠非技术手腕挤进控制信道,华为投资几十亿的5G“三神器”在5G NR
第一阶段业已全部打水漂。
整个5G信道编码又经历一番怎样波澜壮阔的争斗,这背后又隐藏着多少暗流汹涌的阴谋
诡计。“为极解密” 为您最全方位的解析。

THE POSTDOCTORALORL FELLOW is expected to develop a treatment planning
system for interstitial photodynamic therapy of prostate cancer. This
project is funded by a NIH R01 grant and is for a period of at least 2 years
. Current projects focus on developing an integrated system for in-vivo
light delivery and optimization for PDT including: diffuse absorption
spectra to monitor in vivo tissue oxygenation, blood volume, and drug
concentration, real-time fluorescence spectra to monitor drug concentr

或者研究合成/半合成高分子在生物中的应用,象Tissue engineering等,这条路的普遍
问题是各种高分子的生物兼容性问题。
或者把生物大分子当作纯粹根据官能团可推测化学性质的高分子。
我对第一种有些了解,由於生物现象的复杂性,简单的分子链官能团变化而导致的不同化
学性质的高分子,在生物体内,即所谓in vivo, 对蛋白质,细胞的反应大同小异。现在
最讽刺的就是in vitro 的结果常常和in vivo相反。所以除非生物上游有突破,否则只是
盲人摸象。
第二种我也有同样的想法。

来自主题: Macromolecules版 - Is there good method to let nanoparticle
I would not believe QDs like CdSe can ever be used for real "in vivo"
applications, no matter how well you cap it. So the issue is the material of
the nanoparticle core, not the ligands (arms) aroud it. People have been able
to make sort of biocompatible nanoparticles by incorpting PEG and peptides
onto nanoparticle surface, but still there is no way to make them intact in
physilogical conditions for a long time. Nanoparticles with gold or silica
cores are more likely to be used for real in vivo
