This implied that the genetic mutations of HN resulted in antigenic variations of these viruses and the search for new vaccines would be necessary.

这表明， NDV的分子变异已经对NDV的抗原性变异产生了影响，研制新型的疫苗成为必然。

Based on the study in Lotus japonicus, a model legume plant in Papilionoideae, scientific groups led by Luo Da demonstrated that TCP proteins have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants Antirrhinum majus and Lotus japonicus, suggesting a synapomorphic origin for the mechanisms in the control of floral zygomorphy.

以蝶型花亚科的百脉根为研究对象，罗达等研究组阐明了在豆科与其他物种基因组中调控花对称性发育的分子机制具有共源性，揭示了在高等植物花形进化过程中，不同进化关系的开花植物独立地招募TCP基因，调控了两侧对称花发育过程中背腹轴的发育。

The significance of the spatial variation in gene diversity among populations was estimated by per-forming a hierarchical analysis of genetic diversity among populations using the analysis of molecular variance model, as described in Michalakis and Excoffier (1996) and available in ARLEQUIN.

种间基因多样性空间变异的显著性用在分子变异模型上操作的种间遗传多样性层次分析来估计，如同Michalakis和Excoffier (1996)描述的，并且在 ARLEQUIN软件中也有效。

Over the past year, the group evaluated the seven-year follow-up results of therapeutic effects of all-trans retinoic acid and arsenic trioxide (As2O3) combined treatment in newly diagnosed acute promyelocytic leukemia. We also studied the mechanism of therapeutic effects of Imatinib and As4S4 combined treatment in CML cell line and animal model. These two papers were published on PNAS.

过去的一年中，本课题组总结完成了全反式维甲酸和三氧化二砷联合治疗初发急性早幼粒细胞白血病的七年临床随访资料的疗效评估；在慢性粒细胞性白血病，完成了应用As4S4和STI571联合治疗作用的细胞、分子和整体动物水平的机制研究，这两部分工作均已发表于PNAS。

Objective To study the toxic effects of inorganic arsenic on skin fibroblasts proliferation, and to explore the molecular mechanism of sodium arsenite for its role in skin lesions from arsenic contamination.

目的观察亚砷酸钠诱导体外培养的人皮肤成纤维细胞的作用，探讨砷性皮肤损伤的分子机制。

The accumulation of asphaltene in the system depends on the physical structure of ...

在沥青质分子单元叠积过程中，由沥青质的杂原子因素、过渡金属因素、芳香环结构因素和脂肪性侧链因素共同决定的化学作用的影响是第一位的，其中芳香环结构因素和杂原子因素的影响最为显著，而由稠油体系不稳定性构成的物理作用的影响则居于次要地位。

The distributions of the chain radius of gyration and the two-dimensional asphericity are measured. It is found that the DNA molecules exhibit highly anisotropic shape even for circular-form and the mean asphericity is chain length independence.

从测量二维的鍊回旋半径分布发现DNA分子展现高度的非等向性的形状(甚至是环形的DNA也具备此特性)且此特性与鍊长无关。

This paper reviews whether forward movement of the posterior corneal surface occurred, changes in posterior corneal power and curvature, changes in posterior corneal astigmatism and tilt, changes in posterior corneal asphericity and BFS after the surgery.

本文综述了准分子激光屈光性手术后角膜后表面是否发生前移改变、角膜后表面屈光力、曲率、散光度、轴度、非球面特性以及最适球面等是否发生改变的研究进展。

The generalized relationship which correlates the geminal coupling constants with the hybrid orbitals, net atomic charges, bond lengths and bond angles had been employed to obtain one concrete relationship for calculation of the geminal coupling constants 2JCaCbH in aromatic systems.

在前文工作的基础上，本文结合MNDO分子轨道方法和最大键级杂化轨道方法研究得到了计算苯及其取代物中孪位偶合常数2JCCH的多元级性关系式。

These findings would be helpful to understand the molecular mechanisms underlying auxin regulation of root gravitropism in plants.

从这些研究结果可进一步理解生长素调控植物根向地性的分子机理。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
