我家jojo也是这个病,不过今年已经好多了。前年十月第一次是嘴唇先红,再肿,然后溃烂结疤,样子很可
怜,见照片。脾气也很糟,可能是很难受吧。vet诊断为feline eosinophilic granuloma complex,认为是
鸡肉过敏,免疫系统问题。(我不大相信,因为他从小就吃鸡肉,几年都没有问题,我做了很多research, 可惜
这个病因到目前兽医学界无解。)开了prednisolone tablets 和消炎药 Calvamox. 每个月都要去拿药,直到
第二年七月 (长期吃predinsolone对肾不好,急死人了),医生看还没好转,就开了一个极贵的猛药
(steroid类的人药,未经认证为猫药,我不能推荐),吃了一次,jojo反应强烈,吃完药马上大吐,吐了很多
hairball. 然后就慢慢就好了。
这期间吃了一年的Royal Canin的鸭子处方粮, 贵也没办法,认了。最难办的是他的妹妹吃的是不同的粮
(Wellness,有鸡的成分),每次吃饭必须隔离,但都闻出来对方吃的不同,相互嫉妒,经常打架,那段时间
关系非常恶劣,有时还相互偷吃,防不胜防, 整整一年我可头大... 阅读全帖

真是谢谢mm了,下面是我搜到的一个帖子,里面都是猫得了这个病的主人的交流,很多人
都提到了这个病的反反复复,让我焦心不已
很多人也谈到了猫粮的问题,兽医也给我们开了皇家的鸭子猫粮和罐头,但是小白第一次
吃那个鸭子罐头就吐了,所以就没有再给他吃那些鸭子,看来还是要继续吃,mm的猫后来
就一直吃这个鸭子猫粮了吗?

x integers, each integer's range is from 0 to y
the complexity is polynomial in x and y, and exponential in min(x,logy).

Greetings!
My function evaluation sometimes generate complex numbers when I use fmincon
, fminsearch, and fminunc. The optimizations stop or won't converge. Why
this could happen? Can I dump the imaginary part to continue the routine?
Any experience to share?
Many Thanks.

来自主题: Programming版 - Question in C++ complex number implementation
1 class or struct doesn't matter. only difference is default accessibility.
what matters is, complex<> are "literal types". i assume this is for
compatibility and implementation convenience.
2 the default accessibility is for backward compatibility.
3 for floating point calculation, precision matters. why system provides
float, instead of letting everyone use double?

You write the code, and the whole team is supposed to understand/maintain

eveyone has different taste...
I like scalaz, spray.io, but I do not like shapeless.
I think scala's type system is too complex.
But still I and him has one thing in common, Scala is best choice for static
language for now on JVM.

记错了,RbAp46, RbAp48是PRC2, Smch, MBLR是PRC1。

sample buffer: PBS+DNA loading buffer; running buffer: TBE.
我平时run cold RNA都是用这个buffer system没出过问题,不过平时用的gel都是
10% premade gel,room temperature,还是有点不太一样。

upper band有增加我觉得是complex增加的缘故(不考虑极高background的话能fit出
Kd-_-),bottom band确实不应该,我也不知为啥。。。

又遇到行家了,多谢啊!多问几个问题呵呵

我的RNA都做过PAGE purification,产物方面应该没问题。
你说free CTP我没理解。看你下一个回复,是不是不用radio用的其他方法?
嗯我也听说过这种情况但自己没见过。不知道出现这种情况的时候怎么计算percentage
of bound RNA呢?把所有band加起来作为total?另外,怎么说服别人某个band是
complex band其他都是free RNA呢?
第二次被提醒buffer的问题了。一定要试试。多谢!
真没用过这个。多谢建议。

GST-fused protein A 拉下了B,C,D.且ABCD在胞浆和核内都有分布。文献报道BC、BD在
胞浆和核内都有直接的相互作用,但BCD是否在一个复合物未知或未报道。现在猜想
ABCD很有可能在一个复合物,A作为一个scaffold protein的角色。有什么方法说明4个
蛋白或者至少3个蛋白形成一个complex?有没有比较简单点的方法,国内实验室的设备
条件比较限制。

you have to separate the protein complex(es) by FPLC, then check the
component of different fractions.

agree, gel-filtratioin has its limit, thats why I list it on option 2 only
to add some more evidence to the GST, co-IP results.
But if A/B is the hub/scaffold, mutated A/B or KO AB may cause the
disassoation of B C D, then you will see differnt gel-filtration profilings.
through this comparison, you can say A/others are important for forming a
complex.

A, B, C, D are depending on each other for functions? Personally I t... 阅读全帖

你的Pulldown结果表示这些是一个大的Complex,
这可能会是一个比较复杂点的课题。只要A和BCD中任何一个有Interaction,都可能把3
个蛋白都拉下来。甚至还有其他的Player,因此理论上,A和BCD都不结合甚至都可能把
他们拉下来。
要是我,我会先盯着A和B做。最好的办法是用Purified protein来PD,也只有这样才能
证明是direct interaction。因为你在in vivo能把B拉下来,所以如果AB是直接相互作
用的话,在In vitro,应该也能PD下来。

这玩意挺啰嗦的,要做一堆实验,
完全靠co-IP 有假阳性

谢谢!
确实这个问题挺困难,目前还没有什么号的方法。我很头疼,难道我只能靠猜测几个
potential TFs, 然后做ChIP-seq了 (对于我的project)?这样发现某些新东西的可
能性就不大了。各位说的都很有道理:
Shakuras说的DNA长度的问题,目前很多人做的(Bulyk @ Harvard)都只是10-mer,至
于想模拟chromatin之类那么长的DNA我觉得很难。
难道是个悲剧。。。。这个project挺有意思的,以前发过贴问过版上各位可惜没人回
复。
即将拿到ChIP-seq的数据,但是不知道下一步怎么走。如各位说的:
怎样Purify specific的TFs complex,太难了。

但好像complex disease也没有什么别的好的思路

interaction,gene-environment interaction,听起来很有意思,但会不会也是忽悠

上礼拜有个systems biology的会,现在大家都开始搞complex diseases. 所以看上去
很hot, 如果你走大众化的路子,恐怕不会搞出什么新东西。
要搞这个,就是一要手里有病人的资源;二就是要有新的approach。

Hold That Thought
Slowly but surely, scientists are unveiling the complex chemical underpinnings of memory
Sophie L. Rovner
WHEN WAS THE LAST TIME you misplaced your car in a parking lot? Gave you a bit of a scare, didn't it? What about when you blanked on the name of a longtime friend—did you wonder if you were showing the first signs of Alzheimer's disease?
These are not trivial fears.
