丁酸钠对M期同步及非同步的HeLa细胞早G_1期阻断的可逆性

本文采用早熟染色体凝集(PCC)和~3H-TdR显微自显影技术,观察丁酸钠对同步及非同步的HeLa细胞早G_1期阻断的可逆性及其可逆的进程。实验发现丁酸钠对HeLa细胞早G_1期阻断完全是可逆的,且这种可逆是在洗去丁酸钠后立即产生,丁酸钠对HeLa细胞早G_1期阻断的时间点发生在细胞进入S期前的9.5h;发现早G_1期阻断后的恢复必须再经过中、晚G_1期然后才能进入S期.

Composition of sandstone and heavy minerals implies the provenance of Kuqa Depression in Jurassic, Tarim basin, China

The petrological characteristics and heavy mineral assembly of the Jurassic System in Kuqa Basin are consistent with the tectonic evolution, which is the major factor controlling the filling process of Kuqa Basin. Controlled by the source areas at the both sides of the Basin, the matrixes are dominated by sedimentary rock, high-grade metamorphic rock, acid magmatic rock, and the highest heavy mineral assemblage of zircon-garnet-magnetite in the content. According to heavy mineral indexes, the Jurassic strata can be classified into three rhythmic units of heavy mineral. The lower sequence contains abundant heavy minerals and relatively high content of detritus and its matrixes primarily came form the recycling orogen. The assemblage of “zircon-garnet-magnetite” indicates that the sedimentary area in the early evolution period of the basin is relatively near the provenance. The middle sequence is different from the lower sequence in the heavy mineral assemblage and has the different characteristics from that of source rock. The heavy mineral assemblage is “garnet-zircon” with the highest content of garnet and its main matrices are the high-grade metamorphic rock, acid magmatic rock and hydrothermal vein at the northeastern edge of the basin. The middle and upper sequences are characterized by the clast provenance, which is primarily from the recycling orogen at the northern edge of the basin and secondarily from the southern uplift. As a result of the two provenances, the strata with apparent changes of heavy mineral assemblage and index better coincides with the interfaces of the secondary strata sequences, which reflects the denudation history and the filling process of the orogen at the northern edge of the basin.     

Study on the supramolecular structure of sorbic acid intercalated Zn-Al layered double hydroxides and its thermal decomposition

A novel organic-inorganic composite, sorbic acid intercalated zinc aluminum layered double hydroxides （SA-ZnAl-LDHs） has been successfully assembled by a simple direct coprecipitation method. A holistic approach including normal XRD, FT-IR, and UV-Vis measurements and simultaneous TG/DTA/MS and in situ HT-XRD techniques was employed to explore the supramolecular intercalation structure and the thermal decomposition properties of as-syntheslzed SA-ZnAl-LDHs material.
