Item Phloretin ameliorates hepatic steatosis through regulation of lipogenesis and Sirt1/AMPK signaling in obese mice(2020-09-29) Liou, Chian-Jiun; Wu, Shu-Ju; Shen, Szu-Chuan; Chen, Li-Chen; Chen, Ya-Ling; Huang, Wen-ChungAbstract Background Phloretin is isolated from apple trees and could increase lipolysis in 3T3-L1 adipocytes. Previous studies have found that phloretin could prevent obesity in mice. In this study, we investigated whether phloretin ameliorates non-alcoholic fatty liver disease (NAFLD) in high-fat diet (HFD)-induced obese mice, and evaluated the regulation of lipid metabolism in hepatocytes. Methods HepG2 cells were treated with 0.5 mM oleic acid to induce lipid accumulation, and then treated with phloretin to evaluate the molecular mechanism of lipogenesis. In another experiment, male C57BL/6 mice were fed normal diet or HFD (60% fat, w/w) for 16 weeks. After the fourth week, mice were treated with or without phloretin by intraperitoneal injection for 12 weeks. Results Phloretin significantly reduced excessive lipid accumulation and decreased sterol regulatory element-binding protein 1c, blocking the expression of fatty acid synthase in oleic acid-induced HepG2 cells. Phloretin increased Sirt1, and phosphorylation of AMP activated protein kinase to suppress acetyl-CoA carboxylase expression, reducing fatty acid synthesis in hepatocytes. Phloretin also reduced body weight and fat weight compared to untreated HFD-fed mice. Phloretin also reduced liver weight and liver lipid accumulation and improved hepatocyte steatosis in obese mice. In liver tissue from obese mice, phloretin suppressed transcription factors of lipogenesis and fatty acid synthase, and increased lipolysis and fatty acid β-oxidation. Furthermore, phloretin regulated serum leptin, adiponectin, triglyceride, low-density lipoprotein, and free fatty acid levels in obese mice. Conclusions These findings suggest that phloretin improves hepatic steatosis by regulating lipogenesis and the Sirt-1/AMPK pathway in the liver.Item 台灣法庭口譯史:對話性口譯及專業化進程(2015) 陳雅齡; Chen, Ya-Ling本論文主要探討台灣的法庭通譯如何從早期一位介於荷蘭人與原住民社商且帶有負面形象的溝通媒介,演變成今天根據人權觀念,保障外國當事人也能公平取得司法服務的關鍵角色。全文包括兩方面的研究主題以形成研究框架,首要為對話口譯研究,配合口譯專業化討論,筆者據此對台灣四百年來的法庭口譯活動進行有系統的歷史回顧。首先,法庭口譯是對話式口譯的一種,包含來自三方面參與者的溝通,在現代社會多發生在社區中的法庭或偵查庭或警察局,目的在於解決民間訴訟與糾紛,法庭口譯因而也稱為社區口譯或公共服務口譯。不同於會譯口譯,對話口譯員的位置比較明顯,並具有機構內部成員權力不平均的特點 (見Wadensjö, 1998; Hsieh, 2009; Mason, 1999; 任文, 2010)。Wadensjö (1998) 曾探討對話口譯中口譯員的位置、服務與控制性、面子與禮貌策略、忠誠衝突及殖民因素問題。謝怡玲 (2009) 研究醫療性對話口譯的溝通特點與語境特徵,認為口譯員的位置或眼神、使用人稱、話語層次及其他非語言的溝通行為是非常值得討論的面向。Mason (1999) 闡明對話口譯過程中涉及權力與面子,參與架構,角色衝突,忠誠衝突,還有特定的文化社會裏的符號限制問題。其他如任文 (2010) 指出對話口譯員在法庭或醫療情境的主體性意識。這些學者皆不約而同提出,對話口譯員身兼機構守門員、對話過程的協調者與文化語意磋商者三種角色。本論文中研究者對以上議題逐一討論,並繪圖呈現其中的關聯性以形成一種理論模型,作為未來對話口譯活動分析之用。 近年來由於國際人權法律的推進,國際間特別是西方各國特別注重法庭口譯,法庭口譯逐漸趨於專業化。Mikkelson (1996) 特別根據Tseng(1992) 的口譯專業化研究,分析當代社區口譯專業化的過程並提出改進建議。根據這派見解,專業化的特徵以訓練機構出現最早,而以倫理規範最重要,倫理規範對外可贏得社會大眾信任,對內則是規範各成員的隱形工具。本論文中研究者針對台灣法庭口譯的發展,修正Tseng原來為會議口譯設計的專業化模型,作為台灣法庭口譯的專業化模型。 本論文依台灣的法政發展分為五個階段:(1)早期 (1683-1895,包括原住民自至時期、荷蘭西班牙治理時期及明鄭時期),(2)清朝時期 (1683-1895),(3)日據時期 (1895-1945),(4)國民黨專政時期 (1946-2000)與(5)現代。一開始屬於原住民自治時期,荷蘭人曾為台灣建立西方法庭的雛型。進入二十世紀全球化的結果,法律口譯員更呈現多種語言面貌。每個階段由於法政背景不同,各有其值得探討的面向,進展到現代階段法庭口譯終於大致發展出口譯專業化應具備的所有元素,如有系統的訓練課程、專業知識、倫理規範及專業組織。作為一位機構守門員,對話協調和文化磋商者,角色也從昔日的負面形象演變到今天的舉足輕重。由於台灣的司法史經歷很長時期的殖民與被殖民過程,本研究過程也補充了對話口譯理論有關殖民或後殖民口譯討論的不足,研究者結合了口譯理論研究與口譯史,希望這種研究方法對未來口譯研究是一種突破。
