Evaluation of the antioxidant effects of four main theaflavin derivatives through chemiluminescence and DNA damage analyses   总被引：1，自引：0，他引：1  

Wu YY  Li W  Xu Y  Jin EH  Tu YY 《Journal of Zhejiang University. Science. B》2011,12(9):744-751

Theaflavins (TFs) are the dimers of a couple of epimerized catechins, which are specially formed during black tea fermentation. To explore the differences among four main TF derivatives (theaflavin (TF₁), theaflavin-3-gallate (TF₂A), theaflavin-3′-gallate (TF₂B), and theaflavin-3,3′-digallate (TF₃)) in scavenging reactive oxygen species (ROS) in vitro, their properties of inhibiting superoxide, singlet oxygen, hydrogen peroxide, and the hydroxyl radical, and their effects on hydroxyl radical-induced DNA oxidative damage were systematically analyzed in the present study. The results show that, compared with (−)-epigallocatechin gallate (EGCG), TF derivatives were good antioxidants for scavenging ROS and preventing the hydroxyl radical-induced DNA damage in vitro. TF₃ was the most positive in scavenging hydrogen peroxide and hydroxyl radical, and TF₁ suppressed superoxide. Positive antioxidant capacities of TF₂B on singlet oxygen, hydrogen peroxide, hydroxyl radical, and the hydroxyl radical-induced DNA damage in vitro were found. The differences between the antioxidant capacities of four main TF derivatives in relation to their chemical structures were also discussed. We suggest that these activity differences among TF derivatives would be beneficial to scavenge different ROS with therapeutic potential.  相似文献   

越南华文新文学概况及研究述评     

涂文晖 《南京师范大学文学院学报》2015,(1):100-107

越南华文新文学(简称越华文学)形成于抗日战争时期,起初为中国抗战文学的海外版,后来逐步走向本土化。越战时期,以现代诗为代表的越华文学已经形成了自己的特色,在东南亚各国中出类拔萃,至今仍是越华文学难以再现的高峰。长期以来,基于复杂的历史因素,越华文学的资料难觅,研究十分寂寞。如今,在新的历史时期,越华文学正逐步受到研究者的关注,有关资料也渐渐浮出水面。本文一方面梳理了越华文学的发展历程,另一方面对越华文学的研究现状进行反思。  相似文献   

河南新型城镇化建设再思考     

涂冰燕 《黄河科技大学学报》2015,17(3)

在第三次世界城镇化的浪潮中,为创造性地促进内需、解决城乡统筹,城镇化成为破解矛盾的关键抓手.河南是农业大省和人口大省,城镇化的压力较大,因此在新型城镇化建设中难题较多,最主要的是人口转移挑战大,土地和资金等资源支撑不足,气候环境破坏严重.考虑到河南省区域广而发展不平衡的严峻现实,在新型城镇化建设中务必要以协调为主线,以城镇体系的合理布局为原则,以“化农”为根本任务,以城镇低碳经济为方向,合理解决传统城镇化弊病.  相似文献   

Gaming personality and game dynamics in online discussion instructions     

Chih-Hsiung Tu  Cherng-Jyh Yen  Laura Sujo-Montes  Gayle A. Roberts 《Educational Media International》2015,52(3):155-172

Gamification is the use of game mechanics to drive game-like engagements and actions. It applies game mechanics, dynamics and frameworks to promote desired learning behaviours. Positive and effective gamification could enhance learning and engage learners in more social and context-rich decision-making for problem-solving in learning tasks. Effective gamification design should understand the game personalities of learners, social engagement styles, and intrinsic- and extrinsic-motivated user styles initially and evaluate and select appropriate game mechanics, game dynamics, to create ideal gamification instructions. The research question this study investigated is: How will four types of gaming personalities (i.e. Explorer, Socialiser, Killer and Achiever) predict the level of game dynamics in online discussion environments? This study concluded that examining how gaming personalities relate to game dynamics in a gamified online discussion instruction is not sufficient to design effective gamification. It suggests future studies in game instructions should focus on the relationships between game dynamics, gamification contexts, gaming personalities or preferences, dynamic gaming engagement styles, etc.  相似文献   

中国区域二氧化碳排放增长的驱动因素——工业化、城镇化发展的视角     

涂正革  谌仁俊  韩生贵 《华中师范大学学报(人文社会科学版)》2015,54(1)

随着中国工业化、城镇化快速发展,由此所带来的CO2排放问题日渐严重.本文使用引入工业化、城镇化因素的LMDI“两层完全分解法”,将CO2排放变化分解为七大因素效应,从工业化、城镇化发展视角分析了中国1995-2012年30个省份七大部门的CO2排放增长特征.研究发现:经济规模效应和能源强度效应是主导中国CO2排放变化以及造成区域显著差异的根本原因.经济规模扩张是促进CO2排放的决定因素,在绝大部分省份工业化水平低于60％的情况下,经济规模效应仍将继续扮演推动CO2排放增长的最重要因素.反观城镇化与经济规模效应的倒U型关系,已有7个CO2排放大省城镇化水平超过60％的拐点,未来由此所带来的CO2排放增长压力有望得到缓解.  相似文献   

Is small actually big? The chaos of technological change     

Shih-Chang Hung  Min-Fen Tu 《Research Policy》2014

In this paper, we develop themes from complexity and chaos theory that help to explain the technological change process. We apply two quantifiers, correlation dimensions and Lyapunov exponents, to examine the signs and degrees of chaotic technological dynamics. To illustrate our ideas, we study the development of electronic displays from 1976 to 2010, using patent data. The results of the chaos model are matched against the profiles of patent citations. Our analysis contributes to the development of a chaotic model of technological change.  相似文献
