  • Evolutionary Game Analysis of Copyright Protection of Digital Content Products

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-07-26 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Based on the evolutionary game analysis of copyright protection, it is helpful to explore whether the original subject of digital content products has tolerance to counterfeiting behavior, and to explore the strategic choice of implementing copyright protection under different counterfeit levels. It has certain guiding significance for regulating the behavior of market participants in digital content products.[Method/process] Firstly, the evolutionary game model was used to analyze the interest evolution process of original subject and counterfeit subject, and to explore the tolerance of original subject to counterfeiting under copyright protection. Then, by refining the profit function model of both sides of the game, the determinants of the tolerance level of the original subject were explored.[Result/conclusion] The original subject has a certain degree tolerance for the lower level of counterfeiting and zero tolerance for the higher level of counterfeiting. The maximum counterfeit level tolerance is determined by four factors:the counterfeit cross profit coefficient, the income model constant coefficient, the product R&D cost coefficient and the product R&D effort multiples.

  • 多刺绿绒蒿 WD40 基因家族的鉴定及生物信息学分析

    Subjects: Biology >> Botany >> Applied botany submitted time 2021-11-04 Cooperative journals: 《广西植物》

    Abstract: WD40, as a transcription factor family, is widely involved in regulating plant growth, development, secondary metabolite accumulation and environmental adaptation. In order to explore the role of the WD40 family in the growth, development, secondary metabolite accumulation and tolerance, all the WD40 genes of Meconopsis horridula were identified in this study based on the full-length transcriptome sequencing data and conducted bioinformatics analysis of these genes and their encoded proteins. The results were as follows: A total of 19 WD40 genes were identified, and all the proteins included typical WD40 domain, the amino acid numbers and molecular weight of the protein encoded by WD40 genes were 109-758 and 11 830-84 130 kDa, respectively, and most of the proteins localized in the nucleus, and all proteins belonged to hydrophilic protein; Phylogenetic tree analysis showed that WD40 proteins of M. horridula were closely to Papaver somniferum and Macleaya cordata; The promoter region of WD40 gene contained different amounts of hormones or stress-response elements, suggesting that this family genes may be involved in the regulation of various biological processes, such as growth, development and secondary metabolite accumulation; The tertiary structure of WD40 proteins showed that these proteins evolved in different degrees during the evolutionary process. These results can provide a preliminary basis for further research on the specific mechanism of WD40 gene family in response to stress and secondary metabolite accumulation.

  • ALDH1、CXCR4、E-cadherin在胃癌组织中的表达及与淋巴结转移的关系

    Subjects: Medicine, Pharmacy >> Preclinical Medicine submitted time 2018-01-25 Cooperative journals: 《南方医科大学学报》

    Abstract: Objective To investigate the expression of ALDH1, CXCR4 and E-cadherin in gastric carcinoma and their roles in lymphatic metastasis. Methods Surgical specimens from 127 cases of gastric carcinoma were examined for expressions of ALDH1, CXCR4 and E-cadherin immuohistochemistry with 60 adjacent tissues as control. The associations ofALDH1, CXCR4 and E-cadherin with the clinicopathological pfeatures, 5-year survival rate and lymph node metastasis of the patients were analyzed. Results ALDH1, CXCR4 and E-cadherin were positive in 57.5% (73/127), 63.8% (81/127), and 36.2% (46/127) of the gastric carcinoma tissues, respectively, showing significant differences from the rates in the adjacent tissues (P<0.05). The expression of ALDH1 was significantly correlated with TNM stage and lymph node metastasis (P<0.05), CXCR4 was significantly correlated with the invasion depth, differentiation, TNM stage and lymph node metastasis of the tumor (P<0.05), and E-cadherin was significantly correlated with the invasion depth, differentiation and lymph node metastasis (P<0.05). The positivity rates of ALDH1, CXCR4 and E-cadherin were higher in cases with lymph node metastasis than in those without metastasis. E-cadherin expression was inversely correlated with ALDH1 and CXCR4 expression, and the latter two were positively correlated (P<0.001). Overexpressions of ALDH1 and CXCR4 and a decreased expression of E-cadherin were all related to a poor prognosis of the patients (P<0.05). The expressions ofALDH1, CXCR4 and E-cadherin were all independent prognostic factors of gastric carcinoma.Conclusion The expressions ofALDH1, CXCR4and E-cadherin are associatedwith the invasion, metastasis and prognosis of gastric carcinoma, and their combined detection provides important evidence for predictingtheprogressionandprognosisofgastriccarcinoma.

  • 血管紧张素转化酶基因位点多态性与阿尔茨海默病的相关性

    Subjects: Medicine, Pharmacy >> Preclinical Medicine submitted time 2017-12-07 Cooperative journals: 《南方医科大学学报》

    Abstract: Objective To determine the association between the polymorphism of angiotensin converting enzyme (ACE) gene and Alzheimer's disease (AD). Methods This case-control study involved 201 AD patients and 257 healthy subjects matched for age and gender as the control group. Polymerase chain reaction amplification and matrix-assisted laser desorption/ ionization time of flight mass spectrometry were used to examine the rs4291, rs4309, and rs4343 of ACE gene, and the difference in genotypes, allelotype frequencies and haplotype frequencies were analyzed between the two groups. Results No statistic difference was found in the genotype and allelotype frequencies of rs4291 locus between AD and control groups (P> 0.05). A significant difference was found in the genotype and allelotype frequencies of rs4309 between the two groups with a significant increase in the C allelotype frequency in AD group (OR=1.917, 95% CI=1.431-2.568, P<0.05). The difference in the genotype frequency of rs4343 was not significant between the two groups, but the allelotype frequencies differed significantly with a decreased A allelotype frequency in AD group(OR=0.714, 95% CI=0.532-0.957, P=0.024). Analysis of the linkage disequilibrium among the loci of rs4291, rs4309 and rs4343 showed a D’all above 0.65 between one another. Haplotype analysis confirmed the existence of 5 haplotypes, namely ATA, ACA, TCA, TCG and TTG, indicating a negative correlation between haplotype ATA and AD occurrence (OR=0.558, 95% CI=0.420-0.741, P<0.05) and positive correlations of haplotype ACA and TCA with AD occurrence (ACA: OR=4.883, 95%CI=2.267-10.518, P<0.05; TCA: OR=2.269, 95% CI=1.083-4.754, P<0.05). Conclusion The polymorphism of rs4291 may have no relation with the incidence of AD. Polymorphisms of s4309 and rs4343 may be related to AD, and ATA, ACAand TCAhaplotypes composed of rs4291/rs4309/rs4343 may be related to AD.
