贝壳

She sells sea-shells by the sea-shore,And the shells she sells are sea-shells, I'm sure

她在海滨卖海类贝壳，我相信她所卖的贝壳是海贝。

A little girl who picked up a seashell on the beach listened to it before she went to sleep.

听贝壳一个小姑娘在海滩捡了一只贝壳，睡觉前在听它。

If you were walking along the beach and stumbled upon a small seashell and put it on the tip of a condom, you'd have the Inspiral.

如果你在海边耍，被一个小贝壳绊了一下，那就把那贝壳放在套套的头部，这就是"千斤顶"的外型。

Of, relating to, or being a surface characterized by smooth, shell-like convexities and concavities, as on fractured obsidian.

The central point of the spiral on a seashell is theoretically infinite, but nevertheless you can clearly define the end of the seashell's spiral.

换言之，贝壳的螺旋中央，理论上是无限的，不过你可以清楚的定义贝壳螺旋的结束点

In this paper, we studied M. meretrix ferritin, cathepsin B and caspase genes, which are involved in clam larval shell formation, nutrition, metabolism and apoptosis, respectively. We have cloned the three genes, investigated the temporal and spatial expression profile both at gene and protein level in trochophore (L1), D-veliger (L2), pediveliger (L3) and postlarvae (L4). The potential roles of these proteins were analyzed with specific inhibitors during larval development. Firstly, embryos were found developed into trochophore-like larvae with no shell if cultured at gastrula stage in artificial seawater without iron. Shell-like structures were formed only in the presence of iron. The larvae which had been transferred at L1 stage into ASW developed normal shell. This indicated that iron and iron associated protein are important for larval shell formation. The EST sequence which is homologous with ferritin, which is a principal iron metabolic protein, was selected from the M. meretrix cDNA library. The full-length of ferritin subunit cDNA was cloned by RACE. The results of real-time PCR revealed that the MmeFer mRNA expression changed before and after the larval shell formation.

本论文以文蛤幼虫为研究对象，分别对文蛤幼虫发育过程中贝壳形成相关的铁蛋白、营养及变态相关的组织蛋白酶B及变态过程中细胞凋亡相关的caspase三个基因进行了克隆，分析了基因及编码蛋白在担轮幼虫期(L1)、D形幼虫期(L2)、壳顶幼虫期(L3)和稚贝期(L4)的时空表达特征，解析了其可能的功能，并研究了相应酶类的特异性抑制剂作用对幼虫发育过程的影响，进行了目标蛋白的功能验证，详述如下：研究结果显示，在文蛤胚胎发育到原肠胚时放入不含铁离子的人工海水中培养，发育成无壳的畸形，随着人工海水中铁离子添加浓度的升高，幼虫长出壳状组织接近正常状态；而发育到L1期幼虫放入不含铁离子的人工海水中培养却可以发育出正常的壳，推测铁和铁代谢相关蛋白在幼虫贝壳初始形成有重要的作用。
