As the information was being overloaded from time to time, a significant technique should be accomplished by several search engines that exists will use from the databases to eradicate the replicas of data which was available in articles and to present the outcomes of the search to users in terms of percentage of the amount of the data copied from the original file. Plagiarism is the process of bestowing one’s creative ideas as our individual conception. It is does not meant that anybody cannot use other’s considerations or workings, anybody can use their data by giving the actual credit the original users by stating their names in literature or in references and also by giving special note on acknowledgements. Copying the content of the others work is mainly considered to be a big crime in terms of research and in terms of the owning the idea of the others. The main idea of this work is to identify the extent of the data that was being copied or to identify the amount of data that was being copied from other peoples work or their own credited work. Performance of plagiarizing a document is not limited to word files or pdf files, it is possible to plagiarize even images and other files too. Hence, we were focused on finding the plagiarism in word files which includes academics and research articles.

A Collaborative Filtering Recommendation Algorithm Fusing Rating and Time Interval Similarity on Item Attributes

Xiao-hui Cheng,Yu Wu,Yun Deng 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.12

Traditional methods UBCF have limitations of poor recommendation quality and problems of data sparsity. To alleviate these problems, a novel collaborative filtering algorithm is designed, which firstly get the users’ ratings and time intervals for each attribute from the users’ ratings for items, then produce two methods to calculate the similarity between users, introduce a weighting parameters to control the weight between the two similarity methods in order to get a fusion similarity between two users. The results show that this method is able to improve the accuracy of predicted values, resulting in improving recommendation quality of the collaborative filtering recommendation algorithm.

Sodium glucose co-transporter 2 (SGLT-2) inhibitors are newly developed but promising medicine for type 2 diabetes. However, patients with a different renal threshold for glucose excretion (RTG) may have a different reaction to this medicine. Therefore, the objective of this study was to investigate the characteristics of RTG and its impact factors in patients with type 2 diabetes mellitus (T2DM). The clinical and laboratory data of 36 healthy individuals and 168 in-hospital patients with T2DM were collected and analyzed, RTG was calculated using blood glucose (BG) measured by dynamic BG monitoring, urinary glucose excretion (UGE) and estimated glomerular filtration rate (eGFR). The characteristics of RTG were investigated. The risk factors for high RTG were analyzed using non-conditional logistic regression analysis. Our results found that RTG of the T2DM group was higher than that of the healthy individuals (P < 0.05); and 22.22% from the healthy individuals group but 58.33% from the T2DM group had high RTG. Age, duration of diabetes, body mass index (BMI), and homeostasis model assessment insulin resistance index (HOMA-IR) were independently associated with high RTG (P < 0.05). Further stratified analysis revealed that RTG in T2DM patients increased with age, duration of diabetes, and BMI. In conclusion, RTG is increased in patients with T2DM, especially in those with longer diabetic duration, higher BMI, and those who are older. Therefore, these patients may be more sensitive to SGLT-2 inhibitors.

Glycerol steam reforming over Ni/γ-Al2O3 catalysts modified by metal oxides

Cheng-Hua Xu,Zun-Yu Huang,Chuan-Qi Liu,Hui-Wen Xiao,Jun Chen,Yong-Xiang Zhang,Ya-Cong Lei 한국화학공학회 2013 Korean Journal of Chemical Engineering Vol.30 No.3

The metal oxides modified Ni/γ-Al2O3 catalysts for glycerol steam reforming were prepared by impregnation. Characterization results of fresh catalysts indicated that the molybdates modification abated the acidity and the stronger metal-support interaction of Ni/γ-Al2O3 catalysts, leading to a stable catalytic activity. Especially, NiMoLa-CaMg/γ-Al2O3 (NiMoLa/CMA) catalyst exhibited no deactivation along with glycerol complete conversion to stable gaseous products containing 69% H2, 20% CO and 10% CO2 during time-on-stream of 42 h. TPO of spent Ni/γ-Al2O3catalysts modified by different components showed that the carbon deposit on acidic sites and NiAl2O4 species led to catalysts deactivation. A lower reforming temperature and a higher LHSV and glycerol content were helpful to the production of syngas from GSR over NiMoLa/CMA; the reverse conditions would improve the formation of H2.

Xiao Wang,Hui Si,Qi Cheng,Jinchao Kong,Dong Zhao 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.25 No.-

The heat transfer between annular fluidized-bed and the furnace can be enhanced by adding circulative accelerating tubes in the reactor. Cold state experiments were conducted to test the effect of operation conditions on particles flow in fluidized bed with a circulative accelerating tube. Results showed that the spouting velocity, fluidizing velocity and static bed height all had a beneficial effect on particles circulating efficiency. Shorter and moderate outlet needle nozzles were suitable for circulative accelerating tube to maximize circulating rate. What’s more, smaller size particles which had better fluidity should be chosen for the bed material to improve circulating efficiency.

Xiao-wei Zhao,Yong-xin Yang,Dong-wei Huang,Guang-long Cheng,Hui-ling Zhao 대한수의학회 2015 Journal of Veterinary Science Vol.16 No.3

Cows infected with Escherichia (E.) coli usually experience severe clinical symptoms, including damage to mammary tissues, reduced milkyield, and altered milk composition. In order to investigate the host response to E. coli infection and discover novel markers for mastitistreatment, mammary tissue samples were collected from healthy cows and bovines with naturally occurring severe E. coli mastitis. Changesof mammary tissue proteins were examined using two-dimensional gel electrophoresis and label-free proteomic approaches. A total of 95differentially expressed proteins were identified. Of these, 56 proteins were categorized according to molecular function, cellular component,and biological processes. The most frequent biological processes influenced by the proteins were response to stress, transport, andestablishment of localization. Furthermore, a network analysis of the proteins with altered expression in mammary tissues demonstrated thatthese factors are predominantly involved with binding and structural molecule activities. Vimentin and -enolase were central “functionalhubs” in the network. Based on results from the present study, disease-induced alterations of protein expression in mammary glands andpotential markers for the effective treatment of E. coli mastitis were identified. These data have also helped elucidate defense mechanismsthat protect the mammary glands and promote the pathogenesis of E. coli mastitis.

Xiao-Jun Zhuo,Yu Hao,Fei Cao,Song-Fan Yan,Hui Li,Qian Wang,Bi-Huan Cheng,Bin-Yu Ying,Bin-Yu Ying,Sheng-Wei Jin 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-

Acute respiratory distress syndrome is a life-threatening critical syndrome resulting largely from the accumulation of and the inability to clear pulmonary edema. Protectin DX, an endogenously produced lipid mediator, is believed to exert anti-inflammatory and pro-resolution effects. Protectin DX (5 μg/kg) was injected i.v. 8 h after LPS (14 mg/kg) administration, and alveolar fluid clearance was measured in live rats (n = 8). In primary rat ATII epithelial cells, protectin DX (3.605 × 10−3 mg/l) was added to the culture medium with LPS for 6 h. Protectin DX improved alveolar fluid clearance (9.65 ± 1.60 vs. 15.85 ± 1.49, p < 0.0001) and decreased pulmonary edema and lung injury in LPSinduced lung injury in rats. Protectin DX markedly regulated alveolar fluid clearance by upregulating sodium channel and Na, K-ATPase protein expression levels in vivo and in vitro. Protectin DX also increased the activity of Na, K-ATPase and upregulated P-Akt via inhibiting Nedd4–2 in vivo. In addition, protectin DX enhanced the subcellular distribution of sodium channels and Na, K-ATPase, which were specifically localized to the apical and basal membranes of primary rat ATII cells. Furthermore, BOC-2, Rp-cAMP, and LY294002 blocked the increased alveolar fluid clearance in response to protectin DX. Protectin DX stimulates alveolar fluid clearance through a mechanism partly dependent on alveolar epithelial sodium channel and Na, K-ATPase activation via the ALX/PI3K/Nedd4–2 signaling pathway.

Further laboratory researches and clinical evaluation are needed to gather scientific evidence on the efficacy and safety.

Diagnostic Performance of 68Gallium Labelled Prostate-Specific Membrane Antigen Positron Emission Tomography/Computed Tomography and Magnetic Resonance Imaging for Staging the Prostate Cancer with Intermediate or High Risk Prior to Radical Prostatectomy:

Hui Wu,Ting Xu,Xiao Wang,Yong-Bo Yu,Zhong-Yuan Fan,Dan-Xia Li,Lei Luo,Xue-Cheng Yang,Wei Jiao,Hai-Tao Niu 대한남성과학회 2020 The World Journal of Men's Health Vol.38 No.2

Purpose: To compare the diagnostic efficiency of 68Gallium labelled prostate-specific membrane antigen positron emission tomography (68Ga-PSMA PET) and magnetic resonance imaging (MRI) for staging the lymph node metastases (LNMs) in the prostate cancer. Materials and Methods: A broad search of scientific databases including PubMed, EMBASE, Web of Science, Cochrane Database, and Chinese Biomedicine Literature Database (updated prior to November 1st, 2018) was conducted systematically by two reviewers. In this paper, we evaluated the methodological quality of each included article independently and performed a systematic review and meta-analysis to reveal the summary of the diagnostic performance of 68Ga-PSMA PET and MRI in properly identifying LNMs of intermediate- and/or high-risk prostate cancer.Results: Thirteen eligible articles comprising 1,597 patients were included. For LNMs detection, the pooled sensitivity and specificity of 68Ga-PSMA PET were 0.65 (95% confidence interval [CI]: 0.49–0.79) and 0.94 (95% CI: 0.88–0.97), respectively, while the corresponding values of MRI were 0.41 (95% CI: 0.26–0.57) and 0.92 (95% CI: 0.86–0.95). The area under the symmetric receiver-operating characteristic (SROC) curve for 68Ga-PSMA PET and MRI were 0.92 and 0.83, respectively. Conclusions: In intermediate- or high-risk pre-treatment prostate cancer, 68Ga-PSMA PET had a higher sensitivity and a slightly different specificity in probing the LNMs when comparing with MRI. Moreover, the area under the SROC curve indicated that 68Ga-PSMA PET was a more effective weapon for predicting the LNMs prior to radical surgery.
