A novel complex [Zn（Im）2（A-glu）]-0.5H2O（Im = imidazole, A-glu = N-acetyi- L-glutamic acid） has been synthesized from the reaction of A-glu with Zn（CH3COO）2·2H20 in the presence of Im at 65 ℃, and structurally characterized by single-crystal X-ray diffraction. The complex crystallizes in tetragonai, space group P43212 with a = b = 8.9078（6）, c = 43.458（6） A, C26H36N10O11Zn2, Mr = 795.39, V= 3448.3（6） A^3, De = 1.532 g/cm^3, Z = 4,μ（MoKα） = 1.461 mm^-1, F（000） = 1640, the final R = 0.0453 and wR = 0.0992. X-ray analysis reveals that the crystal structure is constructed by mixed iigands. A-glu adopts the bis-monodentate coordination mode linking two adjacent metal ions to form a one-dimensional chain. Zinc（Ⅱ） ions are four-coordinated with a distorted tetrahedral geometry. Luminescent properties of the complex have been inves- tigated.

Considering the intrinsic decoherence proposed by Milburn, we investigate the entanglement between two two-level atoms induced by a Fock state of single-mode quantized radiation field. The time-dependent reduced density matrix of the atoms system is given explicitly, Due to the intrinsic decoheronce, the atoms system will approach a stationary state, where the stationary entanglement depends on the initial states of the field and the atoms.

Domestic pigs are the second most important source of meat world-wide, and the genetic improvement of economic traits, such as meat production, growth, and disease resistance, is a critical point for efficient production in pigs. Through conventional breeding and selection programs in pigs, which are painstakingly slow processes, some economic traits, such as growth and backfat, have been greatly improved over the past several decades. However, the improvement of many polygenetic traits is still very slow and challenging to be improved by conventional breeding strategies. The development of reproductive knowledge and a variety of techniques, including foreign gene transfer strategies, somatic cell nuclear transfer（SCNT） and particularly, recently developed nuclease-mediated genome editing tools, has provided efficient ways to produce genetically modified（GM） pigs for the dramatic improvement of economic traits. In this review, we briefly discuss the progress of genomic markers used in pig breeding program, trace the history of genetic engineering, mainly focusing on the progress of recently developed genome editing tools, and summarize the GM pigs which have been generated to aim at the agricultural purposes. We also discuss the specific challenges facing application of gene engineering in pig breeding, and future prospects.

With the recent emphasis and development of sustainable chemistry, the conversion of biomass feed- stocks into alternative fuels and fine chemicals over various heterogeneous catalysts has received much attention. In particular, owing to their uniform micropores, strong acidity, and stable and rigid frameworks, zeolites as catalysts or co-catalysts have exhibited excellent catalytic performances in many reactions, including hydrodesulfurization, Fischer-Tropsch synthesis, and hydrodeoxygenation. However, the relatively small sizes of the zeolite micropores strongly limit the conversion of bulky biomolecules. To overcome this issue, mesoporous zeolites with pores larger than those of biomolecules have been synthesized. As expected, these mesoporous zeolites have outperformed conventional zeolites with improved activ- ities, better selectivities, and longer catalyst lives for the upgrading of pyrolysis oils, the transformation of lipids into biofuels, and the conversion of glycerol into acrolein and aromatic compounds. This review briefly summarizes recent works on the rational synthesis of mesoporous zeolites and their superior catalytic properties in biomass conversion.

目的探讨利用多层螺旋CT(MSCT)测量成人窦房结动脉的价值。方法对119例患者(男93例,女26例)进行CT冠状动脉成像检查,在轴位和最大密度投影(M IP)图像上分别对图像显示的直径,窦房结动脉起点到上腔静脉口内侧之间的长度、与邻近的升主动脉壁的垂直距离(S-W间距)、与其起源的冠状动脉起点之间的间距(S-O间距)、左侧窦房结动脉起点与左旋支起点之间的距离(LO-O间距)以及窦房结动脉起始段与其起点近段冠状动脉之间的夹角(S-C夹角)进行测量。结果MSCT可以清楚地显示窦房结动脉的起点及走行情况,结合不同的方法可以对以上数据进行测量。结论利用MSCT测得的窦房结动脉有关数据与解剖学结果基本一致,MSCT是显示和测量窦房结动脉的有效工具。
