Alu elements belonging to the short interspersed nuclear elements (SINE) of repetitive elements are present in more than one million copies which altogether represent 10% of the whole human genome. In this study, the roles of Alu tandem sequences in the process of GFP gene (GFP) expression and packing into chromatin of its DNA were studied. To detect the effect of Alu repeats on gene expression, different copies of Alus were inserted GFP downstream respectively in pEGFP-C1 vector. We found that Alu sequences decreased the amount of GFP transcription, the percentage of GFP positive cells and the accessibility to DNase I in length-dependent manner. Inserting Alu caused the production of higher-molecular-mass RNA, indicating Alu sequence did not induce premature transcriptional termination. Tight packing chromatins keep silent and resist to DNase I digestion, which is a general phenomenon. We suggested that head and tail tandem Alu sequences suppressed GFP expression in length dependent manner by triggering chromatin packing.

( Xiu Jing Zhang ),( Xue Lian Xiang ),( Lei Tu ),( Xiao Ping Xie ),( Xiao Hua Hou ) 대한소화기기능성질환·운동학회 2013 Journal of Neurogastroenterology and Motility (JNM Vol.19 No.4

Background/Aims Most recent studies using high-resolution manometry were based on supine liquid swallows. This study was to evaluate the differences in esophageal motility for liquid and solid swallows in the upright and supine positions, and to determine the percentages of motility abnormalities in different states. Methods Twenty-four asymptomatic volunteers and 26 patients with gastroesophageal reflux disease underwent high-resolution manometry using a 36-channel manometry catheter. The peristalses of 10 water and 10 steamed bread swallows were recorded in both supine and upright positions. Integrated relaxation pressure, contractile front velocity, distal latency (DL) and the distal contractile integral (DCI) were investigated and comparisons between postures and boluses were analyzed. Abnormal peristalsis of patients was assessed applying the corresponding normative values. Results In total, 829 swallows from healthy volunteers and 959 swallows from patients were included. (1) The upright position provided lower integrated relaxation pressure, shorter DL and weaker DCI than the supine position. (2) In the comparison of liquid swallows, the mean for contractile front velocity was obviously reduced while DL and DCI were increased in solid swallows. (3) The supine position detected more hypotensive peristalsis than the upright position. The upright position provided more rapid and premature contraction than the supine position but there was no statistically significant difference. Conclusions Supine solid swallows occur with more hypotensive peristalsis. Analysis should be based on normative values from the corresponding posture and bolus.

Wang, Jing-Jing,Wu, Hai-Feng,Sun, Tao,Li, Xia,Wang, Wei,Tao, Li-Xin,Huo, Da,Lv, Ping-Xin,He, Wen,Guo, Xiu-Hua Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

Lung cancer, one of the leading causes of cancer-related deaths, usually appears as solitary pulmonary nodules (SPNs) which are hard to diagnose using the naked eye. In this paper, curvelet-based textural features and clinical parameters are used with three prediction models [a multilevel model, a least absolute shrinkage and selection operator (LASSO) regression method, and a support vector machine (SVM)] to improve the diagnosis of benign and malignant SPNs. Dimensionality reduction of the original curvelet-based textural features was achieved using principal component analysis. In addition, non-conditional logistical regression was used to find clinical predictors among demographic parameters and morphological features. The results showed that, combined with 11 clinical predictors, the accuracy rates using 12 principal components were higher than those using the original curvelet-based textural features. To evaluate the models, 10-fold cross validation and back substitution were applied. The results obtained, respectively, were 0.8549 and 0.9221 for the LASSO method, 0.9443 and 0.9831 for SVM, and 0.8722 and 0.9722 for the multilevel model. All in all, it was found that using curvelet-based textural features after dimensionality reduction and using clinical predictors, the highest accuracy rate was achieved with SVM. The method may be used as an auxiliary tool to differentiate between benign and malignant SPNs in CT images.

Wu, Jing-Jing,Du, Rui-Ping,Gao, Min,Sui, Yao-Qiang,Xiu, Lei,Wang, Xiao Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.5

Silage making has become a significant method of forage conservation worldwide. To determine how tomato pomace (TP) may be used effectively as animal feed, it was ensilaged for 90 days and microbiology counts, fermentation characteristics and chemical composition of tomato pomace silage (TPS) were evaluated at the 30th, 60th, and 90th days, respectively. In addition, 103 lactic acid bacteria were isolated from TPS. Based on the phenotypic and chemotaxonomic characteristics, 16S rDNA sequence and carbohydrate fermentation tests, the isolates were identified as 17 species namely: Lactobacillus coryniformis subsp. torquens (0.97%), Lactobacillus pontis (0.97%), Lactobacillus hilgardii (0.97%), Lactobacillus pantheris (0.97%), Lactobacillus amylovorus (1.9%), Lactobacillus panis (1.9%), Lactobacillus vaginalis (1.9%), Lactobacillus rapi (1.9%), Lactobacillus buchneri (2.9%), Lactobacillus parafarraginis (2.9%), Lactobacillus helveticus (3.9%), Lactobacillus camelliae (3.9%), Lactobacillus fermentum (5.8%), Lactobacillus manihotivorans (6.8%), Lactobacillus plantarum (10.7%), Lactobacillus harbinensis (16.5%) and Lactobacillus paracasei subsp. paracasei (35.0%). This study has shown that TP can be well preserved for 90 days by ensilaging and that TPS is not only rich in essential nutrients, but that physiological and biochemical properties of the isolates could provide a platform for future design of lactic acid bacteria (LAB) inoculants aimed at improving the fermentation quality of silage.

Jiang Xiu Jing,Oh Yong Sik 한국해운물류학회 2023 The Asian journal of shipping and Logistics Vol.39 No.4

The air transportation industry is becoming an increasingly important growth factor for economic development as trade and logistics exchanges between South Korea and China continue to grow. The main objective of this article is to examine the factors that influence air trade between South Korea and 31 Chinese provinces from 2010 to 2019, with the aim of promoting the expansion of air trade between the two countries. The findings suggest that, with the exception of South Korea’s exports to the 31 Chinese provinces, the gross regional domestic product has a significantly positive effect. The effects of distance and personal income on total air trade, air imports and exports are notably negative and positive respectively. Furthermore, foreign direct investment has a positive impact only when South Korea exports to China. The study concludes that, enhancing the volume of air traffic between South Korea and China can be accomplished by directing investments towards inland areas that possess trade-potential, expanding airport infrastructure, and developing regional economic growth. Furthermore, it is suggested that emerging domestic markets should be under close observation due to the changes in the trade structure after the COVID 19.

Man Zhang,Su‑Su Li,Qiao‑Mei Xie,Jian‑Hua Xu,Xiu‑Xiu Sun,Fa‑Ming Pan,Sheng‑Qian Xu,Sheng‑Xiu Liu,Jin‑Hui Tao,Shuang Liu,Jing Cai,Pei‑Ling Chen,Long Qian,Chun‑Huai Wang,Chun‑Mei Liang,Hai‑Liang Huang,Ha 한국유전학회 2018 Genes & Genomics Vol.40 No.10

Although the current glucocorticoids (GCs) treatment for systemic lupus erythematosus (SLE) is effective to a certain extent, the difference in therapeutic effect between patients is still a widespread problem. Some patients can have repeated attacks that greatly diminish their quality of life. This study was conducted to investigate the relationship between HSP90AA2 polymorphisms and disease susceptibility, GCs efficacy and health-related quality of life (HRQoL) in Chinese SLE patients. A case–control study was performed in 470 SLE patients and 470 normal controls. Then, 444 patients in the case group were followed up for 12 weeks to observe efficacy of GCs and improvement of HRQoL. Two single nucleotide polymorphisms (SNPs) of HSP90AA2 were selected for genotyping: rs1826330 and rs6484340. HRQoL was assessed using the SF-36 questionnaire. The minor T allele of rs1826330 and the TT haplotype formed by rs1826330 and rs6484340 showed associations with decreased SLE risk (T allele: PBH = 0.022; TT haplotype: PBH = 0.033). A significant association between rs6484340 and improvement of HRQoL was revealed in the follow-up study. Five subscales of SF-36 were appeared to be influenced by rs6484340: total score of SF-36 (additive model: PBH = 0.026), physical function (additive model: PBH = 0.026), rolephysical (recessive model: PBH = 0.041), mental health (dominant model: PBH = 0.047), and physical component summary (additive model: PBH = 0.026). No statistical significance was found between HSP90AA2 gene polymorphisms and GCs efficacy. These results revealed a genetic association between HSP90AA2 and SLE. Remarkably, HSP90AA2 has an impact on the improvement of HRQoL in Chinese population with SLE.

Zhou, De,Xie, Wan-Zhuo,Hu, Ke-Yue,Huang, Wei-Jia,Wei, Guo-Qing,He, Jing-Song,Shi, Ji-Min,Luo, Yi,Li, Li,Zhu, Jing-Jing,Zhang, Jie,Lin, Mao-Fang,Ye, Xiu-Jin,Cai, Zhen,Huang, He Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-cell lymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectively reviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), ${\beta}2$-microglobulin (${\beta}2$-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predicting the prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-cell-like (GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOP management, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%, P=0.288). Conclusion: Elevated LDH and ${\beta}2$-M levels, positive B symptoms, Ann Arbor stage III/IV, and primary nodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have a better prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment with the addition of rituximab can improve the prognosis of patients with DLBCL.

Surface coordination and excellent anticorrosion performance of strontiumapatite nanocomposite

Xiu-Rui Liu,Min Miao,Jing-Yu Zhang,JIN-KU LIU,Xian-Mei Zhang,Xiao-Gang Wang 한국공업화학회 2019 Journal of Industrial and Engineering Chemistry Vol.80 No.-

A mass-produced, simple and scalable self-heating-based method for the manufacture of surfacecoordination strontiumapatite (SP) nanocomposite with excellent corrosion resistance is proposed. Thereaction heat released from the formation of SP material increases the solubility of benzotriazole (BTA)which achieves reasonable distribution of system energy. The BTA isfirmly adhered on the SP by Sr Ncoordination bond, which acts as barrier impeding on the penetration of the corrosive medium. Scanelectron microscopy (SEM) and X-ray diffraction (XRD) were employed to characterize coatingmorphology and chemical composition. Meanwhile, electrochemical impedance spectroscopy (EIS) datashow that the resultant resistance of strontiumapatite/benzotriazole (SPB) nanocomposite coating was3.02 × 104V cm2, which was improved by 601.8% compared with SP material. The improvement ofcorrosion performance is attributed to the synergistic anticorrosion mechanism that includes theshielding effect, extension of charge transfer paths and formation of multiple passivationfilms. Themethod for organic and inorganic synergistic material provides ideas for the design and synthesis ofanticorrosive materials.
