Xiaoxia Li,Tihai Li,Jianxiong Gao,Houquan Huang,Linbo Li,Jingsheng Li 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.35 No.-
A novel ‘‘green’’ solvent for removing iron and aluminum impurities simultaneously from quartz sandwas presented to replace the outdated industrial strong acids. The solvent is a ‘‘green’’ mixturecomprised nontoxic, renewable acids and a very diluted hydrochloric acid. The new solvent cansignificantly reduce the pollution caused by residual acids and remain the high efficiency in removingimpurities and is harmless to the target product as well. The final optimum removing rate was up to79.1% and 42.3% respectively if its leached residue was washed, then leached again in a 4 g/l Na2CO3solution under ultrasound for 25 min.

Purpose The cancer survival was characterized by following up sampled subgroups of cancer cases from three population-based cancer registries in Northeast China. Materials and Methods Survival analysis was used to analyze 6,871 patients, who had one of the 21 most common cancers based on sampling from the population-based cancer registries of three cities in Liaoning Province. All patients were diagnosed between 2000 and 2002 and were followed up to the end of 2007 by active and passive methods. The 5-year age standardized relative survival rates (ASRS) were estimated for all cancers combined and each of the 21 individual cancers. Results The survival status was traced for 80.8% of 8,506 sampled cancer cases. The 5-year ASRS for all 21 cancers combined was 41.5% (95% confidence interval, 40.3 to 42.7), the highest ASRS was observed for thyroid cancer (85.2%), breast cancer (78.9%), uterine corpus cancer (75.9%), and urinary bladder cancer (70.2%); the lowest 5-year ASRS was noted in pancreatic cancer (8.8%), liver cancer (11.0%), esophageal cancer (18.8), and lung cancer (19.6%). The cancer survival rates in Liaoning cities were similar to those of urban areas in mainland China, but significantly lower than those in Hong Kong, Korea, and Japan. Conclusion The strikingly poor cancer survival rates in three cities of Liaoning Province and in other places in China highlight the need for urgent investment in cancer prevention, early detection, and standardized and centralized treatment.

<P>New types of two-dimensional (2D) boron nitride (BN) were developed as a 2D scaffold material. After modification with ternary deep eutectic solvents (DES, ChCl-caffeic acid-ethylene glycol), the processed BN was applied to the preparation of magnetic molecularly imprinted polymers (MMIPs). In the polymerization of MMIPs, DESs and hydrophobic Fe3O4 magnetite were applied as the functional monomer and magnetically susceptible component, respectively. A 2D ellipsoid material was formed successfully by polymerization on the surface of the processed BN. The proposed 2D-MMIPs were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and nitrogen sorption analysis techniques. The surface area of the 2D-MMIPs was increased using eco-friendly chemicals. The proposed 2D-MMIPs had a 2D oblate structure and a large surface area. The 2D-MMIPs were used for the preconcentration of flavonoids from <I>Ginkgo biloba</I> leaf extracts. High performance liquid chromatography-ultraviolet analysis revealed that the 2D-MMIPs have higher recoveries for the flavonoids (quercetin 96.8%, isorhamnetin 93.6% and kaempferol 94.8%) in <I>Ginkgo biloba</I> leaves than common MMIPs.</P>

One-Dimensional Topological Entities Matching for Heterogenous Data Exchange
Xiaoxia Li,Fazhi He,Xiantao Cai,Zhiyong Huang (사)한국CDE학회 2010 한국CAD/CAM학회 국제학술발표 논문집 Vol.2010 No.8
In the process of feature-based data exchange (FBDE), one-dimensional topological entities are always used as references or operational objects in the source CAD system. To ensure FBDE, the corresponding one-dimensional topological entities in the target CAD system should be found to match the source ones. In this paper we describe in detail an algorithm for supporting the match for FBDE. The algorithm has been used in the procedure recovery architecture. It has efficiently improved the import algorithm used in the UPR.

Li, Xiaoxia,Row, Kyung Ho Elsevier 2017 Journal of chromatography. B, Analytical technolog Vol.1068 No.-
<P><B>Abstract</B></P> <P>A series of ecofriendly ternary deep eutectic solvents (DESs) with different molar ratios were prepared as candidate functional monomers. Three of the optimal ternary DESs as functional monomers were applied to the preparation of molecularly imprinted polymers (MIPs). After synthesis, the proposed polymers were characterized by elemental analysis (EA), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller surface area measurements (BET) and Fourier transform infrared spectroscopy (FT-IR). These MIPs based on ternary DESs with different molar ratios exhibited different absorption capacities of levofloxacin. A sample of levofloxacin (500ng) was dissolved in a millet extractive (10mL). All MIPs were used as SPE adsorbents to purify the extracts. According to characterization result, the ternary DES-3 (1:3:1.5) was joined in the synthetic process of MIP-1. The green ternary DES-3-based MIPs had the best selectivity recovery for levofloxacin (91.4%) from the millet extractive. The best selectivity of MIP-1 was attributed to the novel monomer (ternary DES) in the preparation of the materials. Overall, ternary DES-based MIPs have potential applications as media in many research areas.</P>

Objective: To evaluate the effectiveness of the Frog appliance in three dimensions by using cone-beam computed tomography (CBCT) images. Methods: Forty patients (21 boys and 19 girls), averaged 11.7 years old, with an Angle Class II division 1 malocclusion were included in our study. They had either late mixed dentition or early permanent dentition, and the maxillary second molars had not yet erupted. All patients underwent CBCT before and after the treatment for measuring changes in the maxillary first molars, second premolars, central incisors, and profile. Paired-samples t-test was used to compare the mean difference in each variable before treatment and after the first phase of treatment. Results: The maxillary first molars were effectively distalized by 4.25 mm (p < 0.001) and 3.53 mm (p < 0.05) in the dental crown and root apex, respectively. The tipping increased by 2.25o, but the difference was not significant. Moreover the teeth moved buccally by 0.84 mm (p < 0.05) and 2.87 mm (p < 0.01) in the mesiobuccal and distobuccal cusps, respectively, whereas no significant changes occurred in the root apex. Regarding the anchorage parts, the angle of the maxillary central incisor’s long axis to the sella-nasion plane increased by 2.76o (p < 0.05) and the distance from the upper lip to the esthetic plane decreased by 0.52 mm (p = 0.01). Conclusions: The Frog appliance effectively distalized the maxillary molars with an acceptable degree of tipping, distobuccal rotation, and buccal crown torque, with only slight anchorage loss. Furthermore, CBCT image demonstrated that it is a simple and reliable method for three-dimensional analysis.

Wang Xiaoxia,Yang Jing,Huang Yuyuan,Wu Xiaomin,Wang Licheng,Han Limei,Li Sha,Li Huan,Fu Xiaoying,Chen Hai,Zhu Xiong 한국미생물학회 2020 The journal of microbiology Vol.58 No.9
Two aerobic, Gram-stain-positive, non-motile, non-sporulating coccoid strains, designated ZLJ0423T and ZLJ0321, were isolated from the faeces of Tibetan antelope (Pantholops hodgsonii). Their optimal temperature, NaCl concentration and pH for growth were 28°C, 0.5% (w/v) NaCl and pH 7.5, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains ZLJ0423T and ZLJ0321 were very similar to each other (99.8%) and had a sequence similarity of 97.0% with Georgenia satyanarayanai NBRC 107612T and Georgenia subflava CGMCC 1.12782T. Phylogenomic analysis based on 688 core genes indicated that these strains formed a clade with G. satyanarayanai NBRC 107612T and Georgenia wutianyii Z294T. The predominant cellular fatty acids were anteiso-C15:0, anteiso-C15:1 A and C16:0. The major menaquinone was MK-8(H4). The cell-wall amino acids consisted of alanine, lysine, glycine and aspartic acid, with lysine as the diagnostic diamino acid. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and two unidentified lipids formed the polar lipid profile. The DNA G + C content of both isolates was 73.9 mol%. The digital DNA–DNA hybridization value between strains ZLJ0423T and ZLJ0321 was 91.2%, but their values with closely related species and other available type strains of the genus Georgenia were lower than the 70% threshold. On the basis of polyphasic taxonomic data, strains ZLJ0423T and ZLJ0321 represent a novel species within the genus Georgenia, for which the name Georgenia faecalis sp. nov. is proposed. The type strain is ZLJ0423T (= CGMCC 1.13681T = JCM 33470T).
