CIDE gene expression in adipose tissue,liver, and skeletal muscle from obese and lean pigs     

Yue-qin Qiu  Xue-fen Yang  Xian-yong Ma  Yun-xia Xiong  Zhi-mei Tian  Qiu-li Fan  Li Wang  Zong-yong Jiang 《Journal of Zhejiang University. Science. B》2017,18(6):492-500

The expression of the cell death-inducing DNA fragmentation factor α-like effector (CIDE) family including Cidea, Cideb, and Cidec was significantly increased in mouse and human models of obesity. However, there was less information on these genes’ expression in pigs. Here, we hypothesized that different fat accumulation between lean (Duroc×Landrace×Yorkshire gilts, DLY) and obese (Lantang) pigs was attributed to porcine CIDE-modulating lipid metabolism. Our data showed that Cidea and Cidec were expressed at a high level in adipose tissue, and at a relatively high level in skeletal muscle, whereas Cideb was mainly expressed in the liver in both breeds of pig. Lantang pigs had higher white adipose and skeletal muscle Cidea and Cidec mRNA abundance, and hepatic and muscle Cideb mRNA than DLY pigs. Lipid metabolism-related genes including sterol regulatory element binding protein 1c (SREBP-1c), hepatocyte nuclear factor-4α (HNF-4α), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), fatty acid synthase (FASN), diacylglycerol O-acyltransferase 1 (DGAT1), and DGAT2 showed a higher expression level in adipose tissue from obese pigs than in that from lean pigs. Lantang pigs exhibited higher mRNA abundance for liver SREBP-1c, HNF-4α, and PGC-1α, and higher skeletal muscle SREBP-1c, HNF-4α, PGC-1α, and DGAT2 expression, as compared with DLY pigs. However, the perlipin2 mRNA levels in adipose tissues, liver, and skeletal muscle were significantly lower in obese pigs than in their lean counterparts. Furthermore, plasma non-esterified fatty acid (NEFA), glucose, and triacylglycerol (TAG) levels were greater in obese pigs than in lean pigs. Finally, data from correlation analysis further found that CIDE mRNA expression was positively correlated with back fat thickness (BFT), abdominal fat mass (AFM), and the levels of NEFA, TAG, and glucose in the two breeds. Collectively, these data revealed that the porcine CIDEs possibly modulated lipid metabolism and contributed to the development of fat deposition and obesity in Lantang pigs.  相似文献

美感体验中的三维透视——论《二十四诗品》朦胧美     

吕甜 《襄樊职业技术学院学报》2016,(4):59-62

历年来关于《二十四诗品》的美学研究是层出不穷的,从架构美学到思想美学到生态美学到诗歌美学到理想美学等等,这种高度理论性的美学研究使得整部著作更加具有魅力性。但是这种提炼浓缩后的理论升华在无形中也附加上了论者们的美学理想,使得《二十四诗品》美学价值或多或少地存在着"膨胀"的现象。文章将从美感体验出发,旨在挖掘分析能被直接感知的朦胧美和美的朦胧负担,让《二十四诗品》的美变得更加有迹可循。  相似文献

黑格尔哲学出发点范畴对重构马克思主义哲学的意义     

丁春华  赵天成 《哈尔滨学院学报》2000,(5)

出发点是哲学大厦的地基,对哲学出发点的把握直接关系到对一个哲学体系的理解。在哲学界倡导回到马克思的大方向下,有必要对马克思主义哲学的出发点进行澄清。为了充分、准确地理解马克思主义哲学的出发点,我们追本溯源地探讨了黑格尔如何以“思维与存在的统一”为出发点展开自己的哲学体系,以及马克思如何去其糟粕、取其精华地改造了黑格尔哲学的这一出发点,从而把实践范畴作为自己整个哲学的基础和出发点。  相似文献

考试在中国有着悠久的历史渊源。随着中国历史的变迁,从两千多年前“考试”一词的出现,经历了多少次的变化,直到今天的考试制度的建立。今天的考试制度,就以有代表性的高等学校入学资格考试而论,当然不能认为是尽善尽美的,但它却承担着为国家选拔专业人才和评价教育质量的重任,并且也在不断地改革完善中。考试是工具、是方法,工具是无可指责的,关键在于怎样用它。我们希望它能发挥更积极更广泛的作用,提出了在高等学校入学考试中增加心理测验的构想。  相似文献   

Multi-objective aerodynamic optimization design of high-speed train head shape     

Liang Zhang  Ji-ye Zhang  Tian Li  Ya-dong Zhang 《浙江大学学报(A卷英文版)》2017,18(11):841-854

To improve the aerodynamic performance of high-speed trains (HSTs) running in the open air, a multi-objective aerodynamic optimization design method for the head shape of a HST is proposed in this paper. A parametric model of the HST was established and seven design variables of the head shape were extracted. Sample points and their exact values of optimization objectives were obtained by an optimal Latin hypercube sampling (opt. LHS) plan and computational fluid dynamic (CFD) simulations, respectively. A Kriging surrogate model was constructed based on the sample points and their optimization objectives. Taking the total aerodynamic drag force and the aerodynamic lift force of the tail coach as the optimization objectives, the multi-objective aerodynamic optimization design was performed based on a non-dominated sorting genetic algorithm-II (NSGA-II) and the Kriging model. After optimization, a series of Pareto-optimal head shapes were obtained. An optimal head shape was selected from the Pareto-optimal head shapes, and the aerodynamic performance of the HST with the optimal head shape was compared with that of the original train in conditions with and without crosswinds. Compared with the original train, the total aerodynamic drag force is reduced by 2.61% and the lift force of the tail coach is reduced by 9.90% in conditions without crosswind. Moreover, the optimal train benefits from lower fluctuations in aerodynamic loads in crosswind conditions.  相似文献
