The evolution of solid-liquid interface during BBO single crystal growth was stud- ied by the differential interference microscopy. And the step morphology on (0001) surface of the as-grown crystal was observed by the atomic force microscopy as well. It was found that the transition from a flat solid-liquid interface to a skeletal shape will occur in case of rapid growth. However, AFM images of surface steps revealed morphology differences correlated with crystallographic directions. The steps advancing along direction form the step flow, whereas those steps propagating along direction shape into step segments. Measurements of step heights by AFM indicated that it is the high anisotropy of the dimension of growth unit and step bunching due to the enlargement of concentration difference along the surface that results in the anisotropy of step morphologies.

Objective To evaluate the early and mid-term results of endovascular repair for acute and chronic type B aortic dissection, and to compare the clinical outcomes between the 2 groups. Methods From May 2002 to December 2006, 50 patients with type B aortic dissection were treated by endovascular stent-graft. There were 23 patients in the acute aortic dissection (AAD) group and 27 patients in the chronic aortic dissection (CAD) group. All patients were followed up from 1 to 54 months (average, 17±16 months).The immediate and follow-up clinical outcomes were documented and compared between the 2 groups. Results Placement of endovascular stent-grafts across the primary entry tears was technically successful in all 50 patients. Compared to the CAD group, the AAD group had a higher percentage of pleural effusion (17.4% vs. 0%, P=0.04) and visceral /leg ischemia (26.1% vs 3.7%, P=0.04). Procedure related complications, including endoleak and post-implantation syndrome, occurred more frequently in the AAD group than in the CAD group (21.7% vs 3.7% and 30.4% vs 11.1%, respectively; P=0.08 and P=0.04). Kaplan–Meier analysis showed no difference in the survival rate at 4 years between the 2 groups (86.4% vs 92.3%, P=0.42 by log-rank test). However, the event-free survival rate was higher in patients with chronic dissection than in patients with acute aortic dissection(96.2% vs 73.9%; P=0.02 by log-rank test). Conclu- sions Endovascular repair with stent-graft was safe and effective for the treatment of both acute and chronic type B aortic dissection. However, both immediate and long term major complications occurred more frequently in patients with acute dissection than in those with chronic dissection.

Recombinant ARL1 proteins named ARL-(His)6 and ARL-GST were *** were purified by affinity chromatography. Sera from domestic rabbits immunized with ARL-(His)6 were purified by CNBr-activated sepharose 4B coupled ARL-GST. Polyclonal antibodies were detected by Western ***: Recombinant proteins of ARL-(His)6 with molecular weight of 35.7 KD and ARL-GST with molecular weight of 60.8 KD were highly expressed. The expression levels of ARL-GST and ARL-(His)6 were 15.1% and 27.7 %among total bacteria proteins, respectively. They were soluble, predominantly in supernatant. After purification by non-denatured way, SDS-PAGE showed one band. In the course of polyclonal antibodies purification, only one elution peak could be seen. Western blotting showed positive signals in the two purified proteins and the bacteria transformed with pGEX-4T-1(His)6 C-ARL and pQE-30-ARL ***: Polyclonal antibodies are purified and highly specific against ARL-1 protein. ARL-GST and ARL-(His)6 are highly expressed and purified.

High-resolution imaging through randomly dynamic scattered fields and highly scattered walls is an extensively sought-after capability with potential applications in various fields such as underwater imaging, biomedical imaging, and seeing through fog. Numerous methods have been proposed to unscramble object information from degraded scattered images, resulting in considerable improvements in image contrast in degraded scenarios [1].

通过观测乳状液的析水(油)率、电导率和破乳电压研究了无机盐对石油磺酸钠乳化白油和去离子水所形成的水包油乳状液性能的影响,并利用显微镜观察了乳状液微观状态的变化。结果表明,NaCl和KCl等一价无机盐在一定浓度内能增强乳状液的稳定性,使液滴粒径减小,分布更均匀,彼此间的连接更紧密;超过此浓度后不利于乳状液的稳定,但不会使其转相。高价无机盐会使乳状液转相为油包水型,金属离子半径越小,价态越高,引发转相所需的初始浓度越低;转相后的乳状液稳定性降低,液滴粒径增大,分布均匀程度变差,呈独立球形,稳定性按引发剂MgCl_2、AlCl_3、CrCl_3、CaCl_2、SrCl_2、BaCl_2、FeCl_3的顺序依次减弱。
