Amorphous Co-B alloy nanoparticles grown on graphene sheets were synthesized via a chemical reduc- tion approach and successfully used for an application as a pseudocapacitor. This study aims to improve the capacity and cycling stability of amorphous Co-B alloy nanoparticles grown on conductive graphene sheets. The products were characterized by X-ray powder diffraction, scanning electron microscopy, and transmission electron microscopy. As electrode materials for pseudocapacitors, the amorphous Co-B alloy grown on graphene oxide （Co-B@GO） exhibits a high specific capacitance of 460 F g-1, which is nearly 1.5 times greater than that of bare Co-B nanoparticles at 1 A g-l, The specific capacitance preserved 84% of the initial capacitance even after 1000 cycles at a scan rate of 10 m V-1, suggesting its promising po- tential as pseudocapacitor materials.

Infectious diseases are a sustained threat to social development and public *** infectious diseases,including plague,cholera,anthrax,brucellosis,typhoid fever,meningitis,and even those caused by antimicrobial-resistant bacteria,have been prevalent around the world for a long time,and still trigger outbreaks and long-term epidemics in different countries or regions nowadays(1),and trans-regional spread of diseases has frequently exhibited epidemic patterns.

Simultaneous quantification of lopinavir and ritonavir in human plasma by high performance liquid chromatography coupled with UV detection

作者： xiaoli du Southwest University

Social exclusion has been found to weaken the visual working memory capacity of nonsocial stimuli such as digits, letters and colored squares, while the influence of social exclusion on visual working memory capacity of social stimuli was not be discussed. Previous researches have showed that social excluded participants would show a better performance on social cues tasks. Therefore, by using two experiments, we tested whether social exclusion would increase the visual working memory capacity of social stimuli(experiment1: biology motion(BM);experiment 2: human faces) just as the increased performance on other social cues tasks. In current study, the cyber-ball game was used to manipulate social exclusion and the biology motion(BM: experiment1) and human faces(experiment 2) were used as the social stimuli. Ninety-seven female participants performed the visual working memory ***, we used three different index to estimate participants’ working memory capacity in both experiments. In experiment 1, forty-four participants were be asked to remember 1-5 biology motion. The results of experiment 1 showed that social excluded participants showed a larger working memory capacity in BM than social included group. In experiment 2, fifty-three participants were be asked to remember 1-4 three different emotion(angry, happy, neutral) human faces. The results of experiment 2 showed that compared to control group, social excluded participants showed a larger working memory capacity in all of three different emotional human faces. Together, these two experiments suggested that social exclusion did increase the capacity of social stimuli in visual working memory.

High performance liquid chromatography was coupled with UV detection for simultaneous quantification of lopinavir （LPV） and ritonavir （RTV） in human plasma. This assay was sensitive, accurate and simple, and only used 200μL of plasma sample. Samples were liquid-liquid extracted, and diazepam was used as an internal standard. The chromatographic separation was achieved on a C18 reversed-phase analytic column with a mobile phase of acetonitrile-sodium dihydrogen phosphate buffer （10 mmol L-1, pH 4.80）（60：40, v/v）. UV detection was conducted at 205 nm and the column oven was set at 40℃. Calibration curves were constructed between 0,5-20 μg mL-1 for LPV and 0.05-5 μg mL-1 for RTV. The relative standard deviations were 2.16%-3.20% for LPV and 2.12%-2.60% for RTV for intra-day analysis, and 2.34%-4.04% for LPV and 0.31%-4.94% for RTV for inter-day analysis. The accuracy was within 100%＋10%. The mean extraction recoveries were 79.17%, 52.26% and 91.35% for RTV, LPV and diazepam, respectively. This method was successfully applied to human plasma samples from patients orally administered a salvage regimen of lopinavir-ritonavir tablets.

In traditional analysis, enterprises＇ performance evaluation largely depends on profits indices, which results in the public companies＇ strong pursuit of accounting profits and neglect of net cash flow. It is of great significance to study this phenomenon in public companies for it can help to evaluate their profitability correctly. By making an empirical research on the status quo of the medical public companies＇ accounting profits, net cash flow, receivable and prepaid items, it is found that the phenomenon that the current accounting profits and net cash flow are inconsistent universally exists in the public companies; the current growth rates of accounts receivable, notes receivable, other accounts receivable and accounts prepaid in the companies which the phenomenon exists in are higher than those in other companies and the industrial average, especially for the latter two items; this phenomenon in economically developed areas is more obvious than in other areas. How to avoid the contradiction of accounting profits and net cash flow in the public companies？ Firstly, the credit risk awareness and management should be strengthened. Secondly, cash budget management should be enhanced. Finally, the index system of evaluation of the public companies＇ operating performance should be improved.

Foot-and-mouth disease virus(FMDV) is the causative agent of a highly contagious disease in livestock. The viral proteinaseL^(rop) of FMDV is involved in pathogenicity, and mutation of theL^(rop) SAP domain reduces FMDV pathogenicity in pigs. To determine the gene expression profiles associated with decreased pathogenicity in porcine cells, we performed transcriptome analysis using next-generation sequencing technology and compared differentially expressed genes in SK6 cells infected with FMDV containingL^(rop) with either a wild-type or mutated version of the SAP domain. This analysis yielded 1,853 genes that exhibited a ≥ 2-fold change in expression and was validated by real-time quantitative PCR detection of several differentially expressed genes. Many of the differentially expressed genes correlated with antiviral responses corresponded to genes associated with transcription factors, immune regulation, cytokine production, inflammatory response, and apoptosis. Alterations in gene expression profiles may be responsible for the variations in pathogenicity observed between the two FMDV variants. Our results provided genes of interest for the further study of antiviral pathways and pathogenic mechanisms related to FMDV L^(rop).

提供虚假证明文件罪是规制中介组织人员出具证明文件失范行为的核心罪名。该罪的罪状表述同时具有繁复不简约和模糊不明确两种缺陷,不符合刑法的明确性和概括性要求。提供虚假证明文件罪的主体不断拓展,已开始突破该罪的典型样态及规制目的。行政犯在立法技术上适合选择空白罪状模式,以保证行政犯的稳定性与灵活性。提供虚假证明文件罪作为行政犯,其立法技术应由叙明罪状转为空白罪状。“中介组织”这个概念在我国现有法学体系下具有规范性、确定性和适当的开放性,符合法律规范概念的一般要求,可继续使用。提供虚假证明文件罪侵犯的是市场经济中中介组织人员的职业信用。以法律系统论为理论支撑,可以尝试构建妨害信用的罪名体系,以助力现代诚信社会建设。

拒不履行信息网络安全管理义务罪是基于回应社会发展而增设的一个义务犯类型的轻罪型行政犯。以传统刑法理论研究工具为进路进行、旨在激活本罪的积极适用的做法,存在路径错位,无法达致预期目的。以我国积极的刑事立法和轻罪体系构建为背景,需要对本罪进行以社会治理为视角的研究模式的转型。拒不履行信息网络安全管理义务罪以实体与程序双重前置的行政犯立法技术,体现了行政犯刑事规制与行政管理相结合并向行政管理倾斜的趋势,该罪刑事规制中的功能化的归责考量和刑罚的轻缓化,符合现代刑法参与社会治理的需求,为我国未来对新型行政犯的合理规制提供技术性参考。
