粗厚山羊草－普通小麦核质杂种及其亲本的同工酶分析

分别取粗厚山羊草、普通小麦及其核质杂种（Ｂ８Ｆ１）的茎、叶，利用薄层聚丙烯酰胺凝胶等电点聚焦电泳技术，对酯酶、过氧化物酶两种同工酶进行电泳，并分析它们的酶谱．结果显示：无论茎还是叶，核质杂种的两种酶谱均偏向于提供细胞核的一方──普通小麦，而明显地区别子提供细胞质的一方──粗厚山羊草。认为同工酶主要是由细胞核内的遗传物质所控制．

Na(THF)2(μ2-η5-Cp)(η5,η5,η1-Cp3Yb)(THF)]n: The synthesis and X-ray structure of an anionic organolanthanidepolymer formed via self-assembly

Cp2Yb·2THF reacts with CpNa in 1：1 molar ratio in THF at 40℃ for 2 h, and the in situ generated anionic divalent complex NaYbCp3（THF）n reacts further with an excess of CpH at 40℃ for 48h, after work-up, affording the trivalent anionic ytterbium complex[Na（THF）2（μ2-η^5-Cp） （η^5, η^5,η^1-Cp3Yb）（THF）]n：（1） by oxidation reaction of Cp2Yb with CpH. Crystal structure determination reveals that complex 1 has one-dimension polymeric chains of distinct Na（THF）2（μ2-η^5-Cp） （η^5, η^5,η^1-Cp3Yb）（THF） units, which were formed by the coordination of the bridging Cp ligand with Cp3Yb＇THF and Na（THF）2 in η^5,η^5 mode via self-assembly.     

Effect of density of hydrogen-bonding donor on hydrogen-bonded multilayer buildup

The effect of density of hydrogen-bonding donor （HBD） on the formation of layer-by-layer assemblies of poly（4-vinylpyridine） and poly（4-vinylphenol） was investigated. For this purpose, a series of ethyl-substituted poly（4-vinylphenol） （EsPVPhf） with variable ethyl substitute percentage was synthesized by grafting the phenol moiety along the poly（4-vinylphenol） backbone with 1-bromoethane. UV-vis spectroscopy revealed a uniform deposition process of the hydrogen-bonded multilayer consisting of poly（4- vinylpyridine） （PVPy） and EsPVPhf with variable density of HBD. Notably, it was found that increasing the HBD density of EsPVPhf resulted in a marked decrease of both amount of polymers adsorbed and film thickness, which should be related to the EsPVPhf conformation change from coiled state to extended conformation in ethanol solution. Compared with the effect of charge density in polyelectrolyte multUayer, however, there does not exist a critical density of HBD in our case of hydrogen-bonded multilayer assembly. In addition, surface structures of PVPy/EsPVPhf multilayer films also can be tailored controllably by adjusting HBD density of EsPVPhf. As a result, a new method for tuning the structure of hydrogen-bonding-directed multilayer films was developed.

Progress in non-viral gene delivery systems fabricated via supramolecular assembly

Gene delivery systems are one of key issues that limit the development of gene therapy. The novel non-viral gene delivery systems fabricated via supramolecular assembly have begun to show increasing promising and applications in gene therapy due to its suitable nanometric size,controllable structure and excellent biocompatibility. In this review, the fundamental and recent progress of non-viral gene supramolecular assembly is reviewed. Artificial viruses the future direction of non-viral gene delivery systems are also described.
