有螯的

Peacock tails look a treat and the girls love them, but try dragging one of those things behind you when escaping from a hungry tiger; and the fashion sense of the babirusa is enough to give anyone a splitting headache.

一身靓华衣，你可能会第一时间想起孔雀，另外还有招潮蟹，雄性的招潮蟹有两只大小不同的螯，而且颜色鲜艳，以及具有特别图案。

Primers used in PCR were designed based on the sequence of mitochondrial 16S rDNA (AJ250642 and AF312718) and beta-actin (AY910691) of Eriocheir sinensis which had been deposited in GenBank. PCR analysis using total DNA from muscle, branchia, testis and sperm indicated that 16S rDNA exhibited different expression in the four samples. Beta-actin gene was detected plentiful in all the four tissues/cells and exhibited the same expression pattern. 16S rDNA gene amplification was detected at high levels in muscle and branchia, appreciable low in testis and very low in sperm. The PCR products of 16S rDNA gene were sequenced and aligned with the sequence of 16S rDNA from GenBank (AJ250642 and AF3 12718), and the alignment result showed there was no difference between them.

通过GenBank中的中华绒鳌蟹线粒体16S rDNA序列设计引物，利用PCR扩增方法，以beta-actin做内参，检测了中华绒螯蟹肌肉、鳃、精巢和精子中线粒体16S rDNA扩增情况，发现各组织或细胞beta-actin扩增片段大小、条带宽度和亮度基本一致，表明各模板DNA量基本一致；而在同一DNA浓度下，16S rDNA的扩增片段长度虽一致，但其产物量存在明显差异，精子16s rDNA产物量显著低于其他3种组织，其条带宽度和亮度很弱；16S rDNA扩增产物经测序分析及比对证明与已有序列完全吻合。

These two effects are the results of its function of chelation and antioxidant.

植酸对生态环境有正负两方面的效应，皆是其螯合作用和抗氧化作用的结果。

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

As with other chelating agents, the patients' mineral status should be determined before administering DMPS and repletion of deficient minerals accomplished.

跟其他螯合剂一样，给DMPS前要先检验评估患者体内的矿物质的状况，如有不足要先补充。

Heavy metals in leachates, which can go to the bottom soil layer and the underground water, was increased with the addition of chelates. These leachates can lead to secondary pollution, particularly EDTA.

用螯合诱导剂淋洗土壤后，渗漏液或下层土壤重金属含量增高，同时也有水体富营养化及有机污染的潜在危害，造成二次污染，尤其是施用EDTA。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
