Two gene fragments of DEN-1(GenBank accession number DQ886390)and DEN-2(GenBank accession number DQ886391),differentially expressed between the ocular skin tissues of normal and albino turbot,were isolated by mRNA differential display and sequenced.It was confirmed by RT-PCR method that the expression levels of both DEN-1 and DEN-2 were down-regulated in the ocular skin tissue of albino turbot.The sequence homology search of DEN-1 revealed high sequence homologies with the UGGT genes of zebrafish and cattle,and the Ugcgl1 gene of Norway rat.High sequence homologies of DEN-2 were observed with the eya4 gene(the eye absent homolog 4)from red jungle fowl,zebrafish,human,Norway rat,mouse and dog.

Pentoses are synthesized in the Calvin cycle, derived from hexoses in the PENTOSE PHOSPHATE PATHWAY,and also made by decarboxylation of nucleoside diphosphate sugars.

戊糖在卡尔文循环中合成，来源于磷酸戊糖途径中的己糖，也由核苷二磷酸的糖脱羧形成。

The content of tri-/tetra- antennary complex type N-glycans was decreased and the biantennary complex type N-glycan was increased on the surface of HL-60 cells by the treatment of ATRA or PMA, but the content of high-mannose type/hybrid type N-glycan was increased by these treatments, the change was just opposite to that of SMMC 7721 cells.

ATRA和PMA也均使HL-60细胞表面三/四天线N-糖链减少和二天线N-糖链增加，但却使高甘露糖型/杂合型N-糖链增加。

Di(3,4-dimethyl)benzylidene xylitol as synthesized in the lab from 3,4-dimethyl benzaldehyde and xylitol, and a series of polypropylene samples were prepared based on the amount of the nucleating agent, DMDBX used.

以3，4-二甲基苯甲醛和木糖醇为原料合成1，3-2，4-二（3，4-二甲基）亚苄基木糖醇，将DMDBX作为成核剂使用溶液沉淀法制备DMDBX质量分数分别为0、0.1%、0.3%、0.5%、0.7%、0.9%的聚丙烯样品，采用红外光谱仪、差示扫描量热仪、X射线衍射仪和偏光显微镜等方法，研究了DMDBX对PP结晶结构和结晶性能的影响。

In the simulated experiments, the effects of long-term exposure of dibutyl phthalate on contents of malondialdehyde, solubility carbohydrate, blade pigment, protein, glutathione and amino acid of Vallisneria spiralis L were studied. The cultivation period was 25 days. The effects on the growth of Vallisneria spiralis L under the stress of DBP was also invertigated in this paper. Vallisneria spiralis L was damaged seriously in long-term exposure of high concentration DBP.
