Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects, we estimate the higher-order relativistic contribution and QED correction to the energy under a hydrogenic approximation. The transition energies, wavelengths and oscillator strengths for the 1s23s-1s2np transitions of this ion are calculated.

在计算相对论效应和质量极化效应对体系能量的一级修正的基础上，通过引入价电子的有效核电荷，在类氢近似下，估算了对能量的高阶相对论修正和QED修正，计算了该离子1s23s-1s2np的跃迁能，波长和在三种规范下的振子强度。

A new eucaryotic expression system of recombinant PoIFN-γ was also constructed so that the denaturalization and refolding process is avoided. The target gene coding PoIFN-γ2 mature protein was subcloned into expression vector, transformed into Pichia pastoris, The His〓 Mut〓 phenotype transformants were screened, fermented in flasks and induced by 1％methanol. The expressed product in culture solution and sedimentation have antiviral activity on VSV and immunological activity proved by indirected immunofluorescence antibody and Dot blotting assay.

为了构建可对表达产物修饰、加工的真核表达系统，使表达产物具有自然干扰素的活性，无需变性、复性，我们将PoIFN-γ2成熟蛋白基因连接酵母整合表达载体，电转化毕赤酵母，筛选了His〓Mut〓表型转化子，摇瓶培养，1％甲醇诱导表达，培养上清和菌体裂解上清均有抗VSV病毒活性，经间接免疫荧光抗体检测和Dot blotting鉴定，重组酵母菌诱导表达产物具有免疫活性。

The affinity of a protein cargo for its cognate Kapb receptor or Kapa adaptor influences its nucleocytoplasmic transport efficiency (28) and represents a subtle effector of transport regulation.

一个蛋白体与它同类蛋白受体或者Kapα衔接子的亲和性影响了它的核质运输效率，并且这种亲和性代表着一种微妙的运输调节因子。
