Jiang, Jun,Bai, Zi Long,Chen, Zhi Hui,He, Long,Zhang, David Wei,Zhang, Qing Hua,Shi, Jin An,Park, Min Hyuk,Scott, James F.,Hwang, Cheol Seong,Jiang, An Quan Nature Publishing Group, a division of Macmillan P 2018 NATURE MATERIALS Vol.17 No.1

Erasable conductive domain walls in insulating ferroelectric thin films can be used for non-destructive electrical read-out of the polarization states in ferroelectric memories. Still, the domain-wall currents extracted by these devices have not yet reached the intensity and stability required to drive read-out circuits operating at high speeds. This study demonstrated non-destructive read-out of digital data stored using specific domain-wall configurations in epitaxial BiFeO<SUB>3</SUB> thin films formed in mesa-geometry structures. Partially switched domains, which enable the formation of conductive walls during the read operation, spontaneously retract when the read voltage is removed, reducing the accumulation of mobile defects at the domain walls and potentially improving the device stability. Three-terminal memory devices produced 14 nA read currents at an operating voltage of 5 V, and operated up to T = 85 °C. The gap length can also be smaller than the film thickness, allowing the realization of ferroelectric memories with device dimensions far below 100 nm.

Qing-Li Yang,Ji-Qing Shen,Yan Xue,Xiao-Bing Cheng,Zhi-Hua Jiang,Yi-Chao Yang,Ying-Dan Chen,Xiao-Nong Zhou 대한기생충학열대의학회 2015 The Korean Journal of Parasitology Vol.53 No.6

The nitric oxide (NO) formation and intrinsic nitrosation may be involved in the possible mechanisms of liver fluke-associated carcinogenesis. We still do not know much about the responses of inducible NO synthase (iNOS) induced by Clonorchis sinensis infection. This study was conducted to explore the pathological lesions and iNOS expressions in the liver of mice with different infection intensity levels of C. sinensis. Extensive periductal inflammatory cell infiltration, bile duct hyperplasia, and fibrosis were commonly observed during the infection. The different pathological responses in liver tissues strongly correlated with the infection intensity of C. sinensis. Massive acute spotty necrosis occurred in the liver parenchyma after a severe infection. The iNOS activity in liver tissues increased, and iNOS-expressing cells with morphological differences were observed after a moderate or severe infection. The iNOS-expressing cells in liver tissues had multiple origins.

SMYD3-associated pathway is involved in the anti-tumor effects of sulforaphane on gastric carcinoma cells

Qing-Qing Dong,Qiu-Tong Wang,Lei Wang,Ya-Xin Jiang,Mei-Ling Liu,Hai-Jie Hu,Yong Liu,Hao Zhou,Hong-Peng He,Tong-Cun Zhang,Xuegang Luo 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.4

Sulforaphane (SFN), a natural compound derived from cruciferous vegetables, has been proved to possess potent anti-cancer activity. SMYD3 is a histone methyltransferase which is closely related to the proliferation and migration of cancer cells. This study showed that SFN could dose-dependently induce cell cycle arrest, stimulate apoptosis, and inhibit proliferation and migration of gastric carcinoma cells. Accompanied with these anticancer effects, SMYD3 and its downstream genes, myosin regulatory light chain 9, and cysteine-rich angiogenic inducer 61, was downregulated by SFN. Furthermore, overexpression of SMYD3 via transfection could abolish the effects of SFN, suggesting that SMYD3 might be an important mediator of SFN. To the best of our knowledge, this is the first report describing the role of SMYD3 in the anti-cancer of SFN. These findings might throw light on the development of novel anti-cancer drugs and functional food using SFN-rich cruciferous vegetables.

Song, Qing-Kun,Zhao, Lin,Li, Jun,He, Yu-Ming,Jiang, Cui-Ping,Jiang, Hai-Dong,Qu, Chen-Xu Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Introduction: Squamous cell carcinoma of esophagus (ESCC) is one of the most common cancers in China. Preserved vegetables are processed foods and consumed in high amounts in the high risk areas for ESCC. This study aimed to investigate the relationships of preserved vegetable consumption with ESCC and precancer lesions. Methods: Cases from Yanting cancer hospital with pathological diagnosis of primary cancer, along with controls and individuals diagnosed with precancer lesions by endoscopy with iodine staining were interviewed. Trained staff collected data on dietary habits 1 year before the interview. An unconditional logistic regression model was used to estimate odds ratios of preserved vegetable consumption for precancer lesions and cancer. Results: Adjusting for potential confounders, intake of preserved vegetables (OR=2.92, 95%CI 1.32~6.47) and longer intake period (OR=5.78, 95%CI 2.26~14.80) were associated with higher risk of ESCC. Compared with lowest intake frequency, the highest was associated with a 3.0-fold risk for precancer lesions and 3.59-fold risk for ESCC (both p<0.05). Conclusion: Consumption of preserved vegetables is a risk factor for esophageal lesions in high risk areas. The carcinogenicity of preserved vegetables needs investigation in further studies and the public health strategies for reducing the consumption might be initiated in high risk areas.

양청강 ( Qing Jiang Yang ),정진섭 ( Jin Sup Jung ) 한국유통경영학회(구 한국유통정보학회) 2015 유통정보학회지 Vol.18 No.6

Purpose: Recognizing the significance of mid-sized enterprises (MSEs) in economic growth as a whole, recently a number of governments and researchers have emphasized the necessity of the study on MSEs’ innovation capabilities as a key source of competitiveness. However, the existing studies on innovation capabilities of a firm are rarely analyzed at the level of MSEs. Especially, there are no comparative and empirical research to examine distinctive features of MSEs between Korea and China, despite the increasing level of active trade and relationship through Korea-China Free Trade Agreement (FTA). Research design, data, and methodology: To fill the gaps in the existing studies, this paper attempted to identify key factors influencing on MSEs’ innovation performance in light of Korean and Chinese contexts using existing references. And then we made a questionnaire, which was composed of three key factors [independent variables] - CEO’s innovation orientation, technological innovation capabilities and organizational competencies and a dependent variable. Five-point scale was used for survey data and multiple regression analyses were used as a major methodology. Results: Three independent variables positively affect innovation performance in Korea, whereas an independent variable associated with organizational competencies has no effects on innovation performance in China. Likewise, government support has a moderating effect on the relationship between three independent variables and innovation performance in Korea, but there is no moderating effect between organizational competencies and innovation performance in China. Conclusion: Based on results, the CEO’s innovation orientation, technological innovation capabilities and organizational competencies positively affect innovation performance in Korea and China. However, there are some differences such as a moderating effect of government support between Korean and Chinese MSEs.
