Item type:Item, Functional Characterization of Acinetobacter baumannii Lacking the RNA Chaperone Hfq(2017-10-27) ;Kuo, Han-Yueh ;Chao, Hsuan-Hao ;Liao, Po-Cheng ;Hsu, LongChang, Kai-ChihThe RNA chaperone Hfq is involved in the riboregulation of diverse genes via small RNAs. Recent studies have demonstrated that Hfq contributes to the stress response and the virulence of several pathogens, and the roles of Hfq vary among bacterial species. Here, we attempted to elucidate the role of Hfq in Acinetobacter baumannii ATCC 17978. In the absence of hfq, A. baumannii exhibited retarded cell growth and was highly sensitive to environmental stress, including osmotic and oxidative pressure, pH, and temperature. Compared to the wild-type, the Hfq mutant had reduced outer membrane vesicles secretion and fimbriae production as visualized by atomic force microscopy. The absence of hfq reduced biofilm formation, airway epithelial cell adhesion and invasion, and survival in macrophage. Further, the hfq mutant induced significantly higher IL-8 levels in airway epithelial cells, which would promote bacterial clearance by the host. In addition to results similar to those reported for other bacteria, our findings demonstrate that Hfq is required in the regulation of the iron-acquisition system via downregulating the bauA and basD genes, the stress-related outer membrane proteins carO, A1S_0820, ompA, and nlpE, and the stress-related cytosolic proteins uspA and groEL. Our data indicate that Hfq plays a critical role in environmental adaptation and virulence in A. baumannii by modulating stress responses, surface architectures, and virulence factors. This study is the first to illustrate the functional role of Hfq in A. baumannii.Item type:Item, 草地跳舞 肢體力與動的溝通(2017-10-29) ;林育平 ;Department of Communication and Technology傳播與科技學系以照片方式紀錄《在草地上 野餐跳舞》接觸即興舞蹈活動。Item type:Item, Item type:Item, 總編輯的話(2017-10-29) ;鄭頎 ;Department of Communication and Technology傳播與科技學系本期為喀報272期,共24篇稿件,本期頭題「讀衣II 當書法與時尚相遇」呈現了東西文化結合的藝術展,衝突中卻又帶有和諧;「教育商業化 是學校還是學店?」則是探討台灣現今高等教育亂象。Item type:Item, 最酷的一天 邁向重生之旅(2017-10-29) ;蔡翔宇 ;Department of Communication and Technology傳播與科技學系《最酷的一天》:死亡不過是種狀態,最重要的是在那之前的過程。Item type:Item, 天母搞什麼鬼 萬聖節系列活動(2017-10-29) ;王貞懿 ;Department of Communication and Technology傳播與科技學系10月28日在天母舉行一系列萬聖節活動,大人小孩著奇裝異服參與,人潮洶湧,現場氣氛歡騰。Item type:Item, Item type:Item, 男生也穿運動內衣? 別再誤會啦!(2017-10-29) ;李哲君 ;Department of Communication and Technology傳播與科技學系現今越來越多男性職業運動員,竟然開始穿著像是女性運動內衣的東西,難道胸肌也需要支撐嗎?Item type:Item, TRAPPIST-1 四十光年外的喜訊(2017-10-29) ;戴淨妍 ;Department of Communication and Technology傳播與科技學系NASA於2017年2月22日在《Nature》上公布了令人興奮的研究成果:TRAPPIST-1星系中的三顆行星位於適居帶!Item type:Item, 做中學 峨嵋構築工作坊(2017-10-29) ;賴昀君 ;Department of Communication and Technology傳播與科技學系在峨眉的構築工作坊裡,學生學習竹、木藝等實用技能。Item type:Item, 小男孩樂團 對於夢想堅持(2017-10-29) ;楊巧柔 ;Department of Communication and Technology傳播與科技學系於2015年出道的小男孩樂團,發行多首傳遞正能量的歌曲,渲染聽眾為夢想而努力的情緒。Item type:Item, 汽車要進步 法規卻停步?(2017-10-29) ;嚴銘浩 ;Department of Communication and Technology傳播與科技學系淺談汽車「先進駕駛輔助系統」(Advanced Driver Assistance Systems;ADAS)及其對台灣相關法令的衝擊。Item type:Item, 茲事「體」大 全民的體育改革(2017-10-29) ;簡文怡 ;Department of Communication and Technology傳播與科技學系國體法修法完畢,緊接著是一連串的改選相關作業,面對來勢洶洶的體改浪潮,你,準備好了嗎?Item type:Item, 做事不留名 做工的人(2017-10-29) ;劉翊安 ;Department of Communication and Technology傳播與科技學系在路上看到的每棟大樓、房舍,都是由一群默默無名的工人砌成的,這些做事不留名的人們,平常的工作究竟在做些什麼?Item type:Item, 高溫下的魔幻 黃安福的玻璃夢(2017-10-29) ;葉宜瑩 ;巫尹文 ;Department of Communication and Technology傳播與科技學系黃安福已經踏入玻璃工藝四十多年,除了創作出題材多元的作品外,也致力於推廣、傳承的工作。Item type:Item, 彭詩晴 勇於挑戰的堅定信念(2017-10-29) ;陳咨諭 ;Department of Communication and Technology傳播與科技學系高中時就入選國家代表隊的彭詩晴,本著對籃球的熱情與勇於挑戰的精神,一步步登上更高的籃球殿堂。Item type:Item, 《心靈夜話》 愛在夜闌人靜時(2017-10-29) ;謝瀚陞 ;Department of Communication and Technology傳播與科技學系艾蒂與路易斯喪偶多年,兩人各自過著形隻影單的生活,一直到一日,艾蒂主動敲了路易斯的房門,希望能在痛苦寂靜的夜晚中,找人相伴度過。Item type:Item, 教育商業化 是學校還是學店?(2017-10-29) ;甘愷璇 ;Department of Communication and Technology傳播與科技學系今年七月,反教育商品化聯盟公布學店經營大學排行榜,引發社會對教育商業化的關注。Item type:Item, 紀物書館 記下不凡的時尚夢(2017-10-29) ;蔡璨竹 ;Department of Communication and Technology傳播與科技學系「希望能在台灣做點有趣的事。」一對姐妹創立「紀物書館」的故事,分享她們眼中的時尚世界。Item type:Item, 県道10号線(2017-10-29) ;謝宛蓁 ;Department of Communication and Technology傳播與科技學系在Google街景服務中,沿著日本山口縣佐々並川旁的「県道10号線」往萩市前進的話,會在馬路旁邊看到一個拿著吉他的鹿男。
