Using of the surface plasmon resonance cytosensor for real-time and non-invasive monitoring of cellular effects in living C6 cells induced by PMA

By cell and molecular biology, the traditional life science research has been improved into modern ex-perimental science. Because cell is the basic structural and functional unit of the mysterious life, the study of life phenomena will be ultimately embodied into the study of cell biology. How to acquire a dynamic knowledge of the intricate biomolecular reactivity and process in living cells has become one of the hotspots in recent biological researches. For the complexity of cellular effects,…

Comparative physical mapping of rice BAC clones linked to resistance genes Glh,Bph-3 and xa-5 in Oryza sativa L. and O. granulata Nees et Arn. ex Watt.

Oryza granulata Nees et Arn. ex Watt. is one of the three wild relatives of rice,which are the most valuable for study and utilization in China.In this study,the homology and physical locations of three rice resistance genes,Glh,Bph-3 and xa-5 are comparatively analyzed between O.sativa and O. granulata by Southern blotting and fluorescence in situ hybridization (FISH).The results of Southern blotting indicate that there exist homologous sequences of the tested RFLP markers in O. granulata.By using three bacterial artificial chromosome (BAC) clones scanned by the tested RFLP as probes, FISH signals are detected on both mitotic and pachytene chromosomes in O.sativa and O.granulata.Dual-color FISH demonstrates that two of the three BAC clones (14E16 and 38J9) are located on the short arm of the same chromosome pair in O. granulata. Additionally, colinearity is shown for the two clones between O.sativa and O.granulata. Another BAC clone 44B4 is located on the end of the short arm of other chromosome pair in these two species.Although the phylogenetic relationship between O.sativa and O.granulata is the most distinct in Oryza and these two species have evidently different biological features and ecological habits, the relative lengths and arm ratios of the detected chromosomes and the relative positions of the tested clone signals on chromosomes in O. granulata are quite similar to those in O. sativa.

Nanoengineering of amino - functionalized mesoporous silica nanospheres as nanoreactors

Selective functionalization of mesoporous silica nanospheres (MSNs) is crucial for nanoengineering of MSNs. Herein, we have combined “surface-protected etching strategy” and “cationic surfactant assisted etching strategy” to prepare functionalized MSNs with externally attached amino groups. The externally attached NH2 groups endow the catalysts with excellent catalytic performance for nitroaldol reaction between nitromethane and benzaldehyde. In addition, those NH2-MSNs can also be used to support gold nanoparticles, which display very good catalytic performance for reduction of 4-nitrophenol. It can be envisioned that the synthesis protocol developed in this work could also be extended to nanoengineered MSNs, which provides opportunities for nanoreactors design.     

诗情与诗意间的裂痕——评华兹华斯诗歌中的一点瑕疵

华兹华斯是英国杰出的浪漫主义诗人。他倡导用老百姓的语言入诗,为浪漫主义诗歌运动写下了纲领性文献——《抒情歌谣集二版序》。但他的诗中也存在些瑕疵,即他的一些诗歌中诗情与诗意间有些许的裂痕,这点在与同时代诗人诗作的比较中可看得更加的清晰。而诗情与诗意二者的化合程度却是评判诗作优劣的最终标准之一。艾略特认为英国自17世纪以后诗歌中出现了"感性脱节"现象。其他英国浪漫主义诗人的诗作中也有类似的瑕疵。
