h*******e 发帖数: 1968 | 5 我和老公都是湖南人,特别爱吃川菜,更爱吃比川菜更辣的湖南菜。
关于小孩子吃辣的事情,我想跟大家分享以下的科普以及自己的经验。
首先,辣味不是味觉,而是触觉或者更准确地说是痛觉。
人类的味蕾有几千个,经过多年的研究,找到五种receptors能分辨苦,酸,咸,甜,
鲜(umami)这五种味道,在人类进化的过程中味觉为生存繁衍下来起到非常重要的作
用。人对苦味最敏感,以防止咽下很多种有毒的植物(大多有苦味)。味蕾对酸和咸的
辨别来自味蕾里面的receptors对离子的探测,有助于少吃腐坏或不熟的食物,以及保
持必须的盐分(钠钾离子)。对甜味的感觉最不敏感,写在基因里面的对甜味的热爱,
另人类在早期食物匮乏的时代可以更有效地寻找卡路里和糖分充裕的食物。
Taste Perception: Cracking the Code
http://www.plosbiology.org/article/info:doi/10.1371/journal.pbi
辣味不是真正的味觉,因为味蕾里没有专门分辨辣物质的receptors,辣味也不需要味蕾

你是不是懂得海洛因和可卡因上瘾的道理?懂不懂上瘾后欲罢不能?你说得对量小的时
候这些东西都没有问题。实际上氰化钾量小的时候也没有问题,只要对cytochrome c氧
化酶的抑制程度没有导致线粒体的质子梯度下降,ATP不能生产。
大家说毒品的时候都是指上瘾的剂量纯化或部分纯化的毒品使用。这些毒品引起的极度
愉悦感本事就是在反馈、改变大脑神经受体。比如海洛因改变opiod receptors,可卡
因改变dopamine receptors,尼古丁改变nicotinic receptors。酒精可能影响多重受
体,比如GABA受体。这些都是神经递质的受体。可以改变人的情绪,对外界的感受。
不懂,就不要碰。没有办法了要用,比如止痛,问医生。 |

Nonsense !
如果要讨论物质基础, 那也是如前面coconut 所说的, 记忆跟一种胞内叫
CREB(CAMP response site binding protein)的蛋白有关, 这种蛋白也是
由于NMDA receptor开放, Ca离子内流所激活. CREB主要作用跟合成更多
的突触后NMDA receptor相关, 但这是近几年来的研究课题, 目前还不是很
清楚.
mGluR有很多亚型, 功能跟cAMP有关. 但是一些亚型的作用是根本相反的,
(如mGluR2,3抑制兴奋性神经原内cAMP活动而mGluR1,5反之). 虽然现在有
些人认为在大脑内mGluR跟ionotropic GluR(NMDA, AMPA, KA receptor)
分布有重叠, 但是在hippocampus内未见报道. |

实际上, 我也怀疑KnockOut 的结果, 因为 NMDA receptor 在 CNS 里分布太广, 它
的缺乏很容易导致其他系统功能的破坏. 但是有兴趣的人可以看看
overexpress NMDA receptor 的结果(Tang YaPing, Genetic enhancement
of learning and memory in mice, Nature, 1999, 63-69), 文章讨论了
overexpress NMDA receptor 2B对LTP的增强, 以及对学习和记忆的改善, 应该
比knockout结果更有说服力.
作功能本来就是很困难的一件事情, 为了求全而苛刻的态度对研究很有害. |

the ligand that can bind to your chemotaxis receptor, which cause receptor
internalization and desensitization. Incubate them for 15-30min in medium
without serum or starve them overnight will resensize the migration and
increase receptor expression. If you are sure your culture medium does not

L*********y 发帖数: 322 | 43 Overall, your project sounds interesting. However, you might want to collect
more data or do far more in-depth analysis prior to submitting your story
to top journals. Below are my specific questions:
Where do you obtain this repellent? From plants or from insects?
Can you elaborate on what ecological impacts this repellent has? Can it be
used as insecticide?
If you are sure this repellent is a mixture instead of a pure chemical, can
you identify its chemical components by doing HPLC, per say?

of the hepatocarcinoma cell can be sensitive to HBV, which has been
isolated by a German group. If using any other non-hepatocyte related cell
would be much more convincing.

b******k 发帖数: 2321 | 46 你不觉得他家HBV入cell line后病毒RNA的浓度实在是太低了?如果没记错的话,当年
有人claim说诸如IL6是HBV receptor也有非常弱的data说明cell line OE IL6就能导致
一些病毒颗粒进细胞的,这个效率太低的话总让人怀疑不是真正的receptor,或者至少
只是很多co-receptor之一 |

g*****n 发帖数: 250 | 48 I am 外行人, too. Let me try to convince you.
How did they pick NTCP? They incubated cells with a high concentration (200
nM) of viral protein baits, photo-cross-linked, and immunoprecipitated the
protein complexes. They saw a thick band at 60 kDa. They ran another gel and
cut the band at that position and did MS. NTCP showed up. They believed
that that was the one.
Here are the problems. (1) With a high concentration of baits and cross-
linking, you would pull down a lot of proteins. They admitted... 阅读全帖 |

g*****n 发帖数: 250 | 49 I speculated, yesterday, how they picked NTCP as a candidate receptor for
HBV. There is nothing wrong to select a candidate based on knowledge. The
key is to determine whether that is the one you are looking for with
evidence. Let’s see how they tested whether NTCP is the receptor for HBV.
(1) They transfected NTCP into cells, cross-linked the viral proteins,
and ran Western. Again, overexpression, forced linking, all are too
artificial. They should look at the native NTCP protein, but they ... 阅读全帖 |
