| 1 | Anisotropic NdFeB/SmCoCuFeZr composite bonded magnet prepared by warm compaction process显示文摘Anisotropic NdFeB/SmCoCuFeZr composite bonded magnets were prepared by warm compaction process. The effects of adding SmCoCuFeZr magnetic powder on the properties of anisotropic bonded NdFeB magnet were investigated in this work. The results show that, both magnetic properties and temperature stability of the bonded magnet can be improved by adding fine SmCoCuFeZr magnetic powder. In the present study, the optimal content of SmCoCuFeZr magnetic powder was about 20 wt.%, in this case, the Br, Hcj, and(BH)maxof the NdFeB/SmCoCuFeZr composite magnet achieved 0.943 T, 1250 kA/m, and168 kJ/m^3, respectively. | Mengling Wu Yuping Li Xin Wang Lizhao Chen Yaozhao Mu | 2017 | Journal of Rare Earths2017,35,12: | 4 |
| 2 | Effects of Dietary Intervention on Hyperlipidemia in Eight Communities of Beijing, China显示文摘To examine the effect of community-based dietary intervention on hyperlipidemia. Methods A total of 180 hyperlipidemia individuals with TG>2.26 mmol稬-1(200 mg穌L-1)and/or TC>5.72 mmol稬-1 (220 mg穌L-1) were selected from 428 eligible subjects in eight communities of Beijing. They were randomly divided into intervention group (n=108) and control group (n=72). Dietary intervention was provided for the intervention group for 6 months. Information on dietary intakes, physical examinations and blood samples was collected. Serum lipids were assayed at baseline and endpoint of the study period. Results Respective decrease in dietary intake of total calories, fat, cholesterol and cooking oil by 13.62%, 24.75%, 24.40%, and 22.43%, in the intervention group was observed. The percentages of total calories from fat, carbohydrate and protein appeared to be desirable after study. Reduced body weight and BMI were also observed. There was a respective 5.61% and 7.06 % decrease in total serum cholesterol and low-density lipoprotein cholesterol in the intervention group, while no significant changes were found in the control group. Conclusions Community-based dietary intervention can effectively improve dietary patterns, control body weight, and decrease the levels of total serum cholesterol and low-density lipoprotein cholesterol. | YINGXIAO ZHEN-TAOZHANG JUN-BoWANG WEN-LIZHU YAOZHAO SHAO-FANGYAN YONGLI | 2003 | Biomedical and Environmental Sciences2003,16,2: | 1 |
| 3 | Antioxidant metabolic system and comparative proteomics analysis in winter turnip rape(Brassica rapa L.)under cold stress显示文摘Winter turnip rape(Brassica rapa L.)is widely cultivated in winter in Northwest China,however,its cold-tolerant mechanism remains insufficiently understood.In this study,winter turnip rape cultivar Longyou 7,a cold-tolerant variety,was used as material,whose accumulation of H_(2)O_(2) and O_(2)^(·-),antioxidant enzyme activity as well as differences in protein expression based on two-dimensional gel electrophoresis(2-DE)technique under -4℃ stress were analyzed.Results showed that,production of H_(2)O_(2) and O_(2)^(·-) were increased in Longyou 7 leaves,simultaneously,SOD and POD activities were also obviously rosed up,but the activities of CAT and APX were gradually reduced with the temperature.Thirty-six differential protein spots were successfully identified between control and treatments group by using mass spectrometry analysis.Among them,4 differential protein spots were induced under cold stress,and 2 were inhibited at-4℃.Functional analysis found that these identified proteins mainly participated in photosynthesis,carbohydrate metabolism,defense,protein synthesis,enzyme activity,redox and membrane metabolism,respectively.Additionally,13 proteins'function were still unknown.In conclusion,strong antioxidant capacity and cell defense ability might play important roles in Longyou 7 response to cold stress. | Xiucun Zeng Li Ma Jinhai Yuan Yaping Xie Tianxia Guan Xiaoqin Wang Guotai Ma Yaozhao Xu Wancang Sun | 2022 | Oil Crop Science2022,7,2: | 0 |
