Functional interactions of protein kinase A and C in signalling networks: a recapitulation

On the basis of evidence collected from the literature, we propose a general model by which protein kinase (PK) A and the different PKC isoforms can inversely affect cell growth. Molecular switches, which are able to direct the signal towards antiproliferative or mitogenic pathways, are the different isoforms of Raf and PKC. Conflicting data are also reported and discussed in an attempt to reconcile them. Received 10 November 2005; received after revision 28 December 2005; accepted 3 January 2006

钕铁硼高压物态方程的理论计算

根据混合物体积相加原理,由已知单质组分铁和钕（摩尔比分别为72.32%和26.68%）的Hugoniot数据计算出强磁材料钕铁硼在19 GPa～78 GPa压力范围内的状态方程.计算结果表明,理论计算结果与冲击压缩实验数据符合得很好.D-u关系的平均计算误差为±2.30%,P-V关系的平均计算误差为±9.12%.这表明本文基于Gruneisen模型导出的计算方法,在给定压力区间对钕铁硼这类金属间化合物是适用的;并且有理由预言该算法也适用于其它固体混合物及化合物的高压物态方程研究.

Description of rotational properties of the superheavy nucleus ^256,258,260Rf by projected shell model

Band structure of the Z = 104 nucleus 256Rf has been a recent research focus in nuclear physics. We performed projected shell model calculations for this and some other neighboring Rf isotopes. Specifically, we studied rotational properties of these nuclei and showed that variations in dynamic moment of inertia were sensitive to single-particle structures, which may be useful information for locating the anticipated island of stability. Electromagnetic transition properties were also calculated, and measurable quantities were predicted for further experimental test.
