As the consumption of fructose and saturated fatty acids (FAs) has greatly increased in western diets and is linked with an increased risk of metabolic syndrome, the aim of this study was to investigate the effects of a moderate (10 weeks) and a prolonged (30 weeks) high fructose and saturated fatty acid (HFS) diet on plasma FA composition in rats. The effects of a few weeks of HFS diet had already been described, but in this paper we tried to establish whether these effects persist or if they are modified after 10 or 30 weeks. We hypothesized that the plasma FA profile would be altered between 10 and 30 weeks of the HFS diet. Rats fed with either the HFS or a standard diet were tested after 10 weeks and again after 30 weeks. After 10 weeks of feeding, HFS-fed rats developed the metabolic syndrome, as manifested by an increase in fasting insulinemia, total cholesterol and triglyceride levels, as well as by impaired glucose tolerance. Furthermore, the plasma FA profile of the HFS group showed higher proportions of monounsaturated FAs like palmitoleic acid [16:1(n-7)] and oleic acid [18:1(n-9)], whereas the proportions of some polyunsaturated n-6 FAs, such as linoleic acid [18:2(n-6)] and arachidonic acid [20:4(n-6)], were lower than those in the control group. After 30 weeks of the HFS diet, we observed changes mainly in the levels of 16:1(n-7) (decreased) and 20:4(n-6) (increased). Together, our results suggest that an HFS diet could lead to an adaptive response of the plasma FA profile over time, in association with the development of the metabolic syndrome.  相似文献   

论教师教育者及其专业发展     

郑爽  胡凤阳  张立满 《石家庄学院学报》2012,14(2):93-97

教师教育者在教师教育乃至整个教育发展中发挥着至关重要的作用。他们是专门从事教师教育工作的人,是帮助师范生实现正式社会化的人,是教师教育实践者和教师教育研究者的统一。教师教育者应该根据自身劳动任务的基础性和艰巨性、劳动对象的成人性和期待性、劳动过程的复杂性和创造性、劳动方式的师范性和示范性、劳动价值的潜在性和长效性等方面特点,通过树立专业理想增进身份认同、开展自我研究融合教学和科研、增进合作交流创建教师教育者发展共同体等方式积极促进专业发展。  相似文献

Multi-objective optimization design of bridge piers with hybrid heuristic algorithms     

Francisco J. Martinez-Martin  Fernando Gonzalez-Vidosa  Antonio Hospitaler  Víctor Yepes 《浙江大学学报(A卷英文版)》2012,13(6):420-432

This paper describes one approach to the design of reinforced concrete (RC) bridge piers, using a three-hybrid multi-objective simulated annealing (SA) algorithm with a neighborhood move based on the mutation operator from the genetic algorithms (GAs), namely MOSAMO1, MOSAMO2 and MOSAMO3. The procedure is applied to three objective functions: the economic cost, the reinforcing steel congestion and the embedded CO₂ emissions. Additional results for a random walk and a descent local search multi-objective algorithm are presented. The evaluation of solutions follows the Spanish Code for structural concrete. The methodology was applied to a typical bridge pier of 23.97 m in height. This example involved 110 design variables. Results indicate that algorithm MOSAMO2 outperforms other algorithms regarding the definition of Pareto fronts. Further, the proposed procedure will help structural engineers to enhance their bridge pier designs.  相似文献
