Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。

Splinter Cell Chaos Theory to you for a new challenge and to bring you a great spiritual pleasure.

This was the reason of no mature ovum in worker. But worker has a potential ability to turn into reproductives because of its complete differentiation stage and the growth stage in oogenesis.

由于具有完整的卵母细胞分化期和生长期，在巢群需要的情况下受调节可以进一步发育完成卵黄的形成，因此工蚁具有向繁殖蚁转化的能力。

During the mitosis, the correct separation of sister chromatids is necessary in normal transition from anaphase to telophase and it guarantees exact distribution of DNA. The non-disjuction is the important reason for forming the aneuploid.

在有丝分裂时，姐妹染色单体的正确分离既起到保证遗传物质准确分配的作用，又是分裂细胞从后期向末期过渡所必需的；而姐妹染色单体不分离则是产生非整倍体细胞的重要原因。

Antibodies against col Ⅲ reacted strongly in the entire pterygial stroma. Conclusions Components of ECM are changed in the pterygium: the sub-epithelial connective tissues and vessels are more prominent in the pterygia than in normal conjunctiva tissues, and abnormal fibers are visible only in the deeper subepithelial connective tissues. This study documents the overexpression of LN and col Ⅲ. They may play roles in cellular adherency, migration and angiogenesis. Also this study documents the overexpression of MMP3 which may degrade ECM in the pathogenesis of the pterygium.

结论翼状胬肉组织中ECM的成分较正常球结膜发生改变，有大量的弹性纤维变性、胶原纤维增生及新生血管形成；col Ⅲ在翼状胬肉组织中表达增加，LN及胶原纤维可能对翼状胬肉中血管形成、细胞粘附和迁移及ECM重建起作用；MMP-3在翼状胬肉组织中表达增加，其对ECM成分的降解作用可能有助于翼状胬肉的形成和向角膜中央侵袭。

This investigation include two parts: lThe primary culture, chondroblast induction and evaluation of MSC. 2The chondroblast cultured with compound porous materials PDLLA and PDLLA/chitosan.

"Our findings point to an as yet undefined cellular pathway that includes TBX15 and is involved in the control of body weight," Dr. Doria told Medscape."If these findings are confirmed in other populations, molecules in this pathway could become potential targets for new drugs, although these findings are still preliminary."

Doria博士向Medscape表示，我们的研究发现指出一个尚未定义的细胞路径，其中包含TBX15且和体重控制有关，若这些研究发现在其他研究中确认，此路径中的分子将成为新药的潜在目标，但这些发现尚属初步阶段。
