这个版有人在做神经免疫,想必对这篇文章很感兴趣:
加州大学戴维斯分校科学家的一项最新研究表明,一种免疫系统蛋白分子能调控大
脑神经元之间突触连接的数量。这也显示出,在人们的免疫能力、感染疾病和精神
状态,如精神分裂、孤独症之间可能存在着某种关联。相关研究发表在2月27日出
版的《自然·神经科学》上。
加州大学戴维斯分校神经病与神经生物学、生理与行为学院副教授金伯利·麦卡利
斯特解释说,精神分裂、孤独症以及其他精神错乱等神经疾病与脑神经连接的改变
有关,这些改变影响了大脑正确处理信息的能力。“某些免疫基因和免疫失调也和
孤独症和精神分裂有关系,根据我们的研究,大脑中免疫分子的形成可能会改变脑
神经的连通性。”
他们研究的是一种名为主要组织相容性复合物I型(MHC type I)的蛋白质。10年
前人们就发现,在出生后较晚时的大脑发育关键期,MHC-I型蛋白质与突触连接的
消除有关。而新研究发现了MHC-I型蛋白质的另一项功能,它还能在出生后早期的
大脑发育期间建立起神经元的连接。
无论是啮齿类动物还是人类,MHC-Ⅰ型蛋白质在每个个体之间都不同,免疫系统以
此来区分出“自己”和“异己”,... 阅读全帖

MECHANICAL FAILURE SIMULATION OF AN IN VIVO HUMAN VERTEBRA
ABSTRACT:
Computational tomography-based scans contain information that can be used to
reconstruct a human vertebra and, along with densitometry studies, help in
the understanding of bone failure. An in vivo digital model of a human lumba

ScienceDaily (May 1, 2011) — For more than 50 years, a dominating
assumption in brain research was that nerve cells in the cortex of the
brain are organised in the form of microscopically small columns.
Subsequently, it became a textbook standard that connections are created
predominantly between nerve cells within these columns. In a review
article for the journal Frontiers in Neuroscience, Clemens Boucsein
and colleagues from the Bernstein Centers in Freiburg and Berlin show

来自主题: Biology版 - 问个neuron migration基本问题
The radial glia cells divide asymmetrically and produce precursor/immature
neurons, which migrate along the radial process up towards the cortical
plate.
Neurons were born first,the glia cells were produced later during cortical
development. Both are originated from the radial glia cells. Recently there
are findings suggesting that glia cells divide locally at the upper cortex
to increase the glia population.
Hopefully this is helpful.

本周周二是个值得纪念的日子。第一次操刀切了鼠脑,然后颤抖着去分离海马和皮质。
那一丁点儿脑组织漂在hibernate medium里让我想到了味增汤里漂的嫩豆腐碎片。正值
临近午饭时分,我不争气的咽了下口水。一旦肚子饿了,那么看什么都像食物,也想和
别人讨论食物。我问旁边在分离同一只老鼠的DRG的美国同事,美国人吃不吃动物的脑
子。她大吃一惊,咧了下嘴,然后摇了摇头。我试图和她解释我们中国人“吃啥补啥”
的传统文化精髓,但是她一副不太愿意听的样子。算了算了,我也就吃过一次火锅里的
猪脑,说心里话那并不好吃,从此再没吃过。打消了吃脑子的想法,我开始专心试图按
照hellozero的指示来做实验。
我觉得自己平时做事儿还是挺麻利的,可是在hood用两把不锈钢超尖镊子翻动那丁点儿
大的脑组织,还要做剥离软脑膜,分离血管,切割碎块等等动作,就好象一个单身汉在
摆弄一个刚刚出生的小娃娃,觉得手脚搁在那里都特多余,特别扭,特不对劲,特不自
在。加上眼镜度数不够深,根本就看不清那些精细的结构,下次得记着戴开车用的眼镜
,而不是读书用的眼镜。。。我一边想着,一边眯起眼睛,恨不得把... 阅读全帖

Introduction
Access to highly palatable and calorically rich foods is a major
contributing factor to the increasing rates of obesity worldwide (Caballero,
2007). Eating is essential for survival and is underpinned by the
fundamental physiological need to consume energy. However, our basic
requirements for nutrients and energy to maintain physiological homeostasis
are often exceeded by an abundant source of readily available and conv... 阅读全帖

http://www.scientificamerican.com/article/is-only-child-syndrome-real/
MRI tests revealed differences in brain structure. In the supramarginal
gyrus, a cortical area associated with creativity and imagination,
researchers found more gray matter (linked to intelligence) among only
children. Researchers, however, discovered fewer gray cells in the frontal
brain, more precisely in the medial prefrontal cortex (mPFC), of only
children than those with siblings. This deficit... 阅读全帖

东方人(东亚人),白人(欧洲人)以及黑人(非洲人)。 粗心的狂暴
核心会员7《Race,Evolution and Behavior》/《种族,进化与行为》
摘要 过去20年的研究主要集中于三个主要种族之间的差异,这三个种族是东方人(东亚
人),白人(欧洲人)以及黑人(非洲人)。在这篇论文中我集中讨论这三个种族。
在通过对於脑体积,智力,性格,性行为,繁殖,成长率,生命周期,犯罪以及家
庭稳定等研究,东方人作为一个整体在这个谱线的一端,黑人在另一端,白人在中间。
整体上,东方人显示了较慢的成熟期,较低的繁殖率,较低性活动率,较大的脑体积以
及较高的智商。黑人则完全相反。白人在中间(但更靠近东方人)。

3岁娃,偶然发现一只脚的外侧踝关节下方有个pea sized 硬硬的突起。我自己觉得按

带去看了儿医,儿医说是推的动,问没有食欲变差也没有weight loss,也不痛,摸了
淋巴结都没异常。送去拍了x-ray,说骨头没问题。儿医说要么自己观察一阵子,要么
带去看 pediatric orthopedic specialist。
有儿科/骨科经验的知道有些什么可能原因么?还有什么检查手段可以确诊呢?比如B超
可以检测是否是cyst?
谢谢!
x-ray的结果是这样:
