查询词典 clam

平静的海面造不出优秀的水手。

Average monthly shell increment varied between seaward and shoreward sites at Shengung and Shigung, probably due to differences in related to tidal height, or a combination effect of submergence time and density of the clam.

彰化伸港与西港两地的不同潮汐采样区之公代族群，呈现不同的平均长度成长，这可能是因位於不同潮汐采样区的公代族群，其密度或摄食时间长短的不同所致。

When the NP concentration exceeds 0.025 mg/L, the stability of DNA strands in shellfish will be affected and there will be a risk of carcinogenesis, mutagenesis and teratogenesis. Human health will also be affected due to seafood consumption. On the other hand, the DNA damage level and migration length show some difference among shellfish, oyster and clam exposed to the same nonylphenol concentration. This is because different shellfish species have different immunity to NP.

数据分析结果同时表明，在相同浓度的壬基酚处理组中，扇贝、牡蛎和文蛤血淋巴细胞的破坏率和迁移长度存在种间差异，这可能是由于这三种贝类对NP的免疫程度不同所致，但关于海洋生物对外界干扰因素存在不同免疫力的具体机制以及它们之间的差别，目前国内外的研究还不多见，具体研究还有待进一步的开展。

After Cryopreservation of embryo and larvae of manina clam Ruditapes variegata, the results indicate the survival rate of blastula embryo and vlegier are significantly better than that of trochophore and D-shaped larvae(P.05); the survival rate of blastula embryo is 42.3%(4.0M DMSO) and the effect of high sucrose density is better than that of low sucrose density with the same DMSO dendity.

对杂色蛤胚胎和幼虫的超低温冷冻保存发现，杂色蛤囊胚和面盘幼虫的保存复活率显著高于担轮幼虫和D形幼虫的复活率(P＜0.05)；杂色蛤囊胚的解冻复活率达42.3％(4.0M DMSO)，相同DMSO浓度条件下，高蔗糖浓度组保存效果好于低蔗糖浓度组，但差异不显著(P＞0.05)；在相同蔗糖浓度条件下，抗冻液中DMSO浓度较高组的保存效果好于DMSO浓度较低的组，但差异不显著(P＞0.05)。

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。
