( Liu Xiu-ping ) 중국어문연구회 2016 中國語文論叢 Vol.0 No.76

This paper aims to demonstrate the semantic, functional change of Qian and figure out the cause which affects the loss of dynamic motion among Qian. In this paper, we investigate a large sum of diachronic and synchronic Chinese texts based on Chinese corpus. Evidences are given to show that Archaic Chinese Qian has been a motion verb involved < motion > and < path > in the motion event which was proposed by Talmy, L.(2000a, 200b). However Qian has lost its function of motion gradually and only the function of static location survived in Mandarin Chinese. In order to account for the historical change of Qian, this paper gives a brief review of the distribution and usage about Qian in different Chinese historical stages and classifies the sentences in which Qian occurs into four types: ‘Bare Verb-Qian’, ‘Qian+Common Verb’, ‘Qian+Motion Verb’ and ‘Qian+Common Noun’. In conclusion, we figure out that there are several factors which may result in the loss of the motion about Qian. First, asymmetry between Archaic Qian and Hou. Second, reanalysis of the ‘Qian+Verb’ structure. Third, the change of Chinese conceptualization pattern etc. The emergence and development of 處置式(e.g. BA construction) and 使成式(e.g. SHI construction) in Ancient Chinese has also be a part which may affects the loss of the motion about Qian.

A proteomic approach reveals the differential protein expression in Drosophila melanogaster treated with red ginseng extract (Panax ginseng)

Liu, Qing-Xiu,Zhang, Wei,Wang, Jia,Hou, Wei,Wang, Ying-Ping The Korean Society of Ginseng 2018 Journal of Ginseng Research Vol.42 No.3

Background: Red ginseng is a popularly used traditional medicine with antiaging effects in Asian countries. The present study aimed to explore the changes in protein expression underlying the mechanisms of life span extension and antiaging caused by red ginseng extract (RGE) in Drosophila melanogaster. Methods: A proteomic approach of two-dimensional polyacrylamide gel electrophoresis (2-DE) was used to identify the differential abundance of possible target proteins of RGE in D. melanogaster. The reliability of the 2-DE results was confirmed via Western blotting to measure the expression levels of selected proteins. Proteins altered at the expression level after RGE treatment (1 mg/mL) were identified by matrix-assisted laser desorption/ionization-time of flight tandem mass spectrometry and by searching against the National Center for Biotechnology nonredundant and Uniprot protein databases. The differentially expressed proteins were analyzed using bioinformatics methods. Results: The average survival life span of D. melanogaster was significantly extended by 12.60% with RGE treatment (1 mg/mL) compared to untreated flies. This followed increased superoxide dismutase level and decreased methane dicarboxylic aldehyde content. Based on the searching strategy, 23 differentially expressed proteins were identified (16 up-regulated and 7 down-regulated) in the RGE-treated D. melanogaster. Transduction pathways were identified using the Kyoto Encyclopedia of Genes and Genomes database, and included the hippo and oxidative phosphorylation pathways that play important roles in life span extension and antiaging process of D. melanogaster. Conclusion: Treatment with RGE in D. melanogaster demonstrated that mechanisms of life span extension and antiaging are regulated by multiple factors and complicated signal pathways.

Xiu-Shi Yang,Li-Li Wang,Xian-Rong Zhou,Shaomin Shuang,Zhi-Hua Zhu,Nan Li,Yan Li,Fang Liu,San-Cai Liu,Ping Lu,Guixing Ren,Chuan Dong 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.6

Quantitative detection of protein, fat, starch,and amino acids in foxtail millet using Fourier transformnear-infrared spectroscopy (NIRS) was investigated. Foxtail millet samples (n=259) were analyzed using NIRS. Spectral data were linearized with data from chemicalanalyses. Calibration models were established using apartial least-squares (PLS) algorithm with cross-validation. Optimized models were tested using external validation setsamples with coefficients of determination in the externalvalidation (R2val) of >0.90. Residual predictive deviation(RPD) values were nearly equal to or >2.5 for crudeprotein, alanine, aspartic acid, glutamic acid, isoleucine,leucine, and serine. However, for glycine, histidine,phenylalanine, proline, threonine, tyrosine, and valine, theR2val values were >0.83 and RPD values were nearly equalto or >2.0. For crude fat, total starch, arginine, and lysine,the R2val values were >0.70 and RPD values were >1.5. NIRS is a rapid determination tool for foxtail milletbreeding, and for quality control.

Digital Controller Candidate for Point-of-load Synchronous Buck Converter in Tri-mode Mechanism

Xiu, Li-Mei,Zhang, Wei-Ping,Li, Bo,Liu, Yuan-Sheng The Korean Institute of Power Electronics 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.4

A digital controller with a low-power approach for point-of-load synchronous buck converters is discussed and compared with its analog counterpart to confirm its feasibility for system integration. The tri-mode digital controller IC in $0.35{\mu}m$ CMOS process is presented to demonstrate solutions that include a PID, quarter PID, and robust RST compensators. These compensators address the steady-state, stand-by, and transient modes according to the system operating point. An idle-tone free condition for ${\Sigma}-{\Delta}$ DPWM reduces the inherent tone noise under DC-excitation. Compared with that of the traditional approach, this condition generates a quasi-pure modulation signal. Experimental results verify the closed-loop performances and confirm the power-saving mechanism of the proposed controller.

Liu, Hai-Bo,Peng, Yu-Ping,Dou, Chang-Wu,Su, Xiu-Lan,Gao, Nai-Kang,Tian, Fu-Ming,Bai, Jie Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Aim: Glioma cancer is the most common type of adult brain tumor. Recent genome-wide association studies (GWAS) have identified various new susceptibility regions and here we conducted an extensive analysis of associations between 12 single nucleotide polymorphisms (SNPs) and glioma risk. Methods: A total of 197 glioma cases and 197 health controls were selected, and 9 SNPs in 8 genes were analyzed using the Sequenom MassARRAY platform and Sequenom Assay Design 3.1 software. Results: We found the MAF among selected controls were consistent with the MAF from the NCBI SNP database. Among 9 SNPs in 8 genes, we identified four significant SNP genotypes associated with the risk of glioma, C/C genotype at rs730437 and T/T genotype at rs1468727 in ERGF were protective against glioma, whereas the T/T genotype at rs1799782 in XRCC1 and C/C genotype at rs861539 in XRCC3 conferred elevated risk. Conclusion: Our comprehensive analysis of nine SNPs in eight genes suggests that the rs730437 and rs1468727 in ERGF, rs1799782 in XRCC1 gene, and rs861539 in XRCC3 gene are associated with glioma risk. These findings indicate that genetic variants of various genes play a complex role in the development of glioma.

CCNG2 Suppressor Biological Effects on Thyroid Cancer Cell through Promotion of CDK2 Degradation

Li, Wei-Juan,Liu, Ge-Ling,Yu, Fang,Xiang, Xiu-Xiu,Lu, Yi-Fang,Xiao, Hong-Zhen,Shi, Yan-Ping Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

This study aimed to analyze the expression and clinical significance of cyclin G2 (CCNG2) in thyroid carcinoma and the biological effects of CCNG2 overexpression in a cell line. Immunohistochemistry and Western blotting were used to analyze CCNG2 protein expression in 63 cases of thyroid cancer and normal tissues to allow the relationship with clinical factors to be assessed. CCNG2 lentiviral and empty vectors were transfected into the thyroid cancer K1 cell line. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were applied to detect the mRNA and protein levels of CCNG2. MTT assay and cell cycle were also conducted to assess the influence of up-regulated expression of CCNG2 on K1 cell biology. The level of CCNG2 protein expression was found to be significantly lower in thyroid cancer tissue than normal tissues (P<0.05). Western blot: The relative amount of CCNG2 protein in thyroid cancer tissue was respectively found to be significantly lower than in normal tissues (P<0.05), correlating with lymph node metastasis, clinic stage and histological grade (P<0.05), but not gender, age or tumor size (P>0.05). Loss of CCNG2 expression correlated significantly with poor overall survival time on Kaplan-Meier analysis (P<0.05). The results for biological functions showed that K1 cell transfected CCNG2 had a lower survival fraction, a greater percentage in the G0/G1 phases, and lower cyclin-dependent kinase 2 (CDK2) protein expression compared with K1 cells non-transfected with CCNG2 (P<0.05). CCNG2 expression decreased in thyroid cancer and correlated significantly lymph node metastasis, clinic stage, histological grade and poor overall survival, suggesting that CCNG2 may play important roles as a negative regulator in thyroid cancer K1 cells by promoting degradation of CDK2.

Qiu, Meng,Ren, Wen Xiu,Jeong, Taeho,Won, Miae,Park, Geun Young,Sang, David Kipkemoi,Liu, Li-Ping,Zhang, Han,Kim, Jong Seung The Royal Society of Chemistry 2018 Chemical Society reviews Vol.47 No.15

<P>Phosphorene, also known as single- or few-layer black phosphorus (FLBP), is a new member of the two-dimensional (2D) material family and has attracted significant attention in recent years for applications in optoelectronics, energy storage and biomedicine due to its unique physicochemical properties and excellent biocompatibility. FLBP is regarded as a potential biological imaging agent for cancer diagnosis due to its intrinsic fluorescence (FL) and photoacoustic (PA) properties and negligible cytotoxicity. FLBP-based photothermal and photodynamic therapies have emerged with excellent anti-tumour therapeutic efficacies due to their unique physical properties, such as near-infrared (NIR) optical absorbance, large extinction coefficients, biodegradability and reactive oxygen species (ROS) or heat generation upon light irradiation. Furthermore, FLBP is a promising drug delivery platform because of its high drug-loading capacity due to its puckered layer structure with an ultralarge surface area, and FLBP is size-controllable with facile surface chemical modification. Because of the marked advantages of FLBP nanomaterials in biomedical applications, an overview of the latest progress and paradigms of FLBP-based nanoplatforms for multidisciplinary biomedical applications is presented in this tutorial review.</P>

Hybridization Using a New Male-sterile Germplasm as the Female Parent in Chinese Jujube

Jiu-rui Wang,Xiu-mei Cui,Li Dai,Ping Liu,Jin Zhao,Meng-jun Liu 한국원예학회 2015 원예과학기술지 Vol.33 No.3

This study identified a new male-sterile germplasm of Chinese jujube, named male-sterile No. 2 (JMS2), and achieved controlled hybridization using that germplasm as the female parent. The anthers of JMS2 before flower bud opening became shrunken, dingy yellow and much smaller than normal ones, and they changed to brown after anthesis. No pollen was observed in anthers of JMS2 and its male-sterile trait remained stable over different years. A total of 1,642 fruits were obtained from ten intra- and interspecific cross combinations via controlled hybridization from 2008 to 2012 using JMS2 as the female parent. Of those, 27.3% produced seeds, on average (0-72.6%). The rate of fruit with seed (RFS) was significantly different between cross combinations or years. Compared to other cross combinations, the RFS in the combination of JMS2 × ‘Xingguang’ (a Chinese jujube cultivar with high resistance to jujube witches’ broom disease) and JMS2 × ‘Xing16’ (a sour jujube genotype) remained high in different years and reached means of 48.7 and 58.1%, respectively. Finally, 150 plantlets were regenerated from immature embryos, and 51 of them were randomly selected and identified to be authentic hybrids using amplified fragment length polymorphism (AFLP) markers. This is the first report of hybrids obtained from a cross between Chinese jujube and sour jujube.
