刹那间的芳华，曾以为是最美的瞬间。­
结局隐退了微笑，落叶浸透在不断蔓延的季节中，一层层的布满尘埃。­
回忆那曾经的温暖，恰是在这个季节开始，又在这个季节止步。­
漠然，风冷，相同的情景，却再也没有了相同的人。­
­
转眼之间的陌生，转身之间的陌路，没有任何由来，只是生命里最绚烂的一场幻觉。­
尽情奢华，这种不断被人证明的虚妄，如烟火，短暂，绚烂。­
毫无任何沾染，就像邂逅一场胜景，摆出各种苍凉的姿势。­
夕阳斑斑驳驳的洒在手心里，又慢慢褪去颜色。­
顿时惊醒，有些东西，即便再舍不得也要放手,mercurial vapor，因为我们始终没有办法抓住。­
很多时候，很多东西真的输给了时间­

在时间的十字路口，你曾坚定的拉着我的手，说着永恒。
几经辗转，路还在，只是岁月已经渐渐的模糊了身影，
现实向左，诺言向右，还会认为那是弥坚的幸福吗？
似曾相识的路，却走着毫不相干的人,louboutin，总抱着梦幻想，物是人未非，
奈何，总逃不掉命运的安排，时间依旧还是过不去的坎。
一些东西老是挥之不去，纠结于心底，也许是性格使然。
有人说，是你太过执着，可是要释然谈何容易。
伪装一种超脱自然的姿态，企盼被人发现，却又不想被人看穿。
来往的穿梭，虽知是徒劳，但始终不肯放弃，
花已落，空留残香未尽；人还在，只是和落寞有染。

文字释放着心中苍凉，只是有时候需要一个温暖的去处。­
多年以后,franklin et marshall，当一切云淡风轻的时候，我会不会笑着说：当时只道是寻常。­


　
常常停下脚步仰望天空，总希望世界就这样一直湛蓝下去。
可是，很多时候，我们总是要隔着玻璃生活，阳光透过玻璃的时候，总会失掉温度。
有时候常想，如果自己浓缩成一片薄薄的云,abercrombie and fitch paris，就这样被风吹着到处飘散该有多好。
一个人没有羁绊，没有束缚，独自平衡着这个世界的黑与白。
季节随时间逝去，夹带着枯黄散落到世界各地，辗转在人世的各个角落,christian louboutin。
晨雾模糊了过路人的眼睛，天空在悄然中昏睡,abercrombie paris，盎然与繁华已经不在。
终究还是留下一个绕不回去的轨迹，距离慢慢伸向边沿。
等到想用手去抓住的时候，已经像断线的纸鸢，徒留那一寸丝线。

Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.
An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.
As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.
Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.
To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.
They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.
According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.
