about this blog

this is merely to denote myself about my body.

mainly on the record of some morphological, anatomial, and medical aspects.

主要是記述在我學我的身體時得到的一些拉七拉雜的資料,不過我想可能不是對我自己有用而已,所以有一些我會多多少少地改成中文化。all the news may be the important informations so i would translate to short notes here. [2010.05.29]

MicroRNA expression and turnover are regulated by neural activity in the retina and brain

ScienceDaily (2010-06-01) -- Scientists in Switzerland have found that microRNAs, small RNA regulators of gene expression, are up- and down-regulated in the retina during light-dark adaptation and in response to synaptic stimulation in hippocampal and cortical neurons. This important discovery provides an unexpected function for microRNAs: it shows that they are able to regulate rapidly the expression of synaptic proteins, which are involved in synapse plasticity and memory formation.
