在真核生物中,环状RNA(circular RNA,circRNA)是一种重要的转录本。该研究证明了水痘-带状疱疹病毒(varicella-zoster virus,VZV)感染过程中可产生病毒来源的circRNA。该研究通过联合二代与三代深度circRNA测序,绘制了高分辨率的细胞和病毒circRNA图谱。接着,在VZV感染的细胞以及带状疱疹病人组织样品中,通过多种实验技术手段进一步验证VZV感染可产生大量病毒circRNA。此外,该研究发现了许多与VZV潜伏相关转录本同源的circRNA(circVLTSlytic)。为了分析这些circVLTSlytic的生物学功能,利用细菌人工染色体系统在基因组DNA水平,对circVLT进行突变。结果发现,circVLT是VZV复制的非必需分子,但circVLTsSlytic外显子5下游的突变可导致VZV对阿昔洛韦敏感性增加。该研究首次证明了VZV感染可产生具有生物学功能的病毒来源circRNA,这为带状疱疹的防治提供了新的思路。

酸类、糖类等不稳定组分的存在是制约热解油直接用作生物燃料的主要因素。为了解决此问题,提出采用Al_(2)(SO_(4))_(3)催化剂将这些不稳定成分酯化为燃料类化合物的途径。首先,分别以单模型化合物左旋葡萄糖或乙酸为原料,考察各种金属硫酸盐催化其转化制备乙酰丙酸乙酯或乙酸乙酯的能力,筛选出催化性能最好的催化剂;其次,以左旋葡萄糖和乙酸的模型混合物为原料,探究Al_(2)(SO_(4))_(3)催化同时转化制备酯类的最佳反应条件;最后,以真实热解油为原料,验证Al_(2)(SO_(4))_(3)在最佳反应条件下催化酯化的可行性。结果表明,酯化后热解油中大部分酸、糖、醛消失,同时产生大量的酯和缩醛,酯类和缩醛类占改性热解油总色谱面积的39.5%。Al_(2)(SO_(4))_(3)能有效将热解油中的酸类、糖类等不稳定组分酯化为燃料类化合物,可为热解油转化制备生物燃料提供借鉴。

By using the complex variable method and conformal mapping, the diffraction of flexural waves and dynamic stress concentrations in thick plates with a cavity have been studied. A general solution of the stress problem of the thick plate satisfying the boundary conditions on the contour of an arbitrary cavity is obtained. By employing the orthogonal function expansion technique, the dynamic stress problem can be reduced to the solution of an infinite algebraic equation series. As an example, the numerical results for the dynamic stress concentration factor in thick plates with a circular, elliptic cavity are graphically presented. The numerical results are discussed.

Journal of Materials Science & Technology 2001年第4期17卷 409-412页

作者： N.Hansen Materials Research Department, Risφ National Laboratory,dk-4000 Roskilde, Denmark Mat. Res. Dept. Ris. Natl. Lab. DK-4000 Roskilde Denmark

The microstructural evolution during plastic deformation is described as grain subdivision on a finer and finer scale with increasing strain. Key structural features are dislocation boundaries and high angle boundaries. These boundaries have characteristic parameters which are used in a comparison of deformation microstructures produced under different conditions.
