| 1 | Effects of dietary vitamin E on muscle vitamin E and fatty acid content in Aohan fine-wool sheep显示文摘value for consumers. Several laboratories have evaluated the effects of vitamin E on the fatty acid(FA) composition of muscle in sheep. However, little information is available on wool sheep, even though wool sheep breeds are an important source of mutton, especially in northern China where sheep are extensively farmed. The present study was designed to address the effects of vitamin E on muscle FA composition in male Aohan fine-wool sheep. Methods: Forty-two male Aohan fine-wool lambs(5 mo old) with similar initial body weight were randomly divided into seven groups and fed diets supplemented with 0(control group), 20, 100, 200, 1,000, 2,000, or 2,400 IU/sheep/d vitamin E for 12 mo. Three lambs from each group were slaughtered to measure vitamin E and FA content in the longissimus lumborum(LL) and gluteus medius(GM) muscles. Results: Vitamin E concentrations in the LL and GM increased significantly after 12 mo of vitamin E supplementation(P < 0.05). However, this increase did not occur in a dose-dependent manner because the muscle vitamin E concentration was highest in the 200 IU/sheep/d group. Dietary vitamin E supplementation also caused a significant reduction in SFA content and an increase in monounsaturated FA(MUFA) content in the LL and GM(P < 0.05). All six doses of vitamin E significantly increased cis9 trans11-conjugated linoleic acid(c9t11-CLA) content in the LL compared with the control group(P < 0.05). Conclusions: Dietary supplementation with vitamin E increased muscle vitamin E content and improved the nutritional value of mutton by decreasing SFA content and increasing MUFA and c9t11-CLA contents in Aohan fine-wool sheep. These effects were greatest in sheep fed a diet containing 200 IU/sheep/d vitamin E. | Kun Liu Suyun Ge Hailing Luo Dubing Yue Leyan Yan | 2013 | Journal of Animal Science and Biotechnology2013，4，4： | 6 |
| 2 | Carbon Doping Triggered Efficient Electrochemical Hydrogen Evolution of Cross-Linked Porous Ru-MoO_(2) Via Solid-Phase Reaction Strategy显示文摘The defect-free structure of Mo-based materials is a“double-edged sword”,which endows the material with excellent stability,but limits its chemical versatility and application in electrochemical hydrogen evolution reaction(HER).Carbon doping engineering is an attractive strategy to effectively improve the performance of Mo-based catalyst and maintain their stability.Herein,we report a cross-linked porous carbon-doped MoO_(2)(C–MoO_(2))-based catalyst Ru/C–MoO_(2) for electrochemical HER,which is prepared by the convenient redox solid-phase reaction(SPR)of porous RuO_(2)/Mo_(2)C composite precursor.Theoretical studies reveal that due to the presence of carbon atoms,the electronic structure of C–MoO_(2) has been properly adjusted,and the loaded small Ru nanoparticles provide a fast water dissociation rate and moderate H adsorption strength.In electrochemical studies under a pH-universal environment,Ru/C–MoO_(2) electrocatalyst exhibits a low overpotential at a current density of 10 mA cm^(-2) and has a low Tafel slope.Meanwhile,Ru/C-MoO_(2) has excellent stability for more than 100 h at an initial current density of 100 mA cm^(-2). | Jialin Cai Jianye Yang Xin Xie Jie Ding Leyan Liu Wanyu Tian Yushan Liu Zhiyong Tang Baozhong Liu Siyu Lu | 2023 | Energy & Environmental Materials2023，6，1： | 0 |
