| 1 | Centrifugal casting processes of manufacturing in situ functionally gradient composite materials of Al-19Si-5Mg alloy显示文摘Cylindrical components of in situ functionally gradient composite materials of Al-19Si-5Mg alloy were manufactured by centrifugal casting. Microstructure characteristics of the manufactured components were observed and the effects of the used process factors on these characteristics were analyzed. The results of observations shows that, in thickness, the components possess microstructures accumulating lots of Mg2Si particles and a portion of primary silicon particles in the inner layer, a little Mg2Si and primary silicon particles in the outer layer, and without any Mg2Si and primary silicon particle in the middle layer. The results of the analysis indicate that the rotation rate of centrifugal casting, mould temperature, and melt pouring temperature have evidently affected the accumulation of the second phase particles. Also, the higher the centrifugal rotation rate, mould temperature, and melt pouring temperature are, the more evident in the inner layer the degree of accumulation of Mg2Si and primary silicon particles is. | XIE Yong LIU Changming ZHAI Yanbo WANG Kai LING Xuedong | 2009 | Rare Metals2009，28，4： | 11 |
| 2 | Molecular mechanism of non-alcoholic fatty liver disease induced and aggravated by chronic stress through HSL/ATGL-FFA which promotes fat mobilization显示文摘Objective:To study the effects of social stress(CS)and social stress combined with high-fat diet on fat mobilization as a candidate mechanism for the induction or aggravation of non-alcoholic fatty liver disease(NAFLD).Methods:Thirty-two male Wistar rats(250±10 g)were randomly allocated to a blank control group(BC),a high-fat diet group(HFD),a CS group,and a combined CS and high-fat diet group(CS t HFD).Rats were sacrificed and tissues were collected after 8 weeks.Liver and body mass were measured and used to calculate the liver index.Serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),and free fatty acids(FFAs)were measured.Liver sections were examined microscopically after oil red O and hematoxylin and eosin staining.The relative mRNA expression of acetyl-CoA carboxylase(ACCase),hydroxymethylglutaryl coenzyme A(HMG-CoA)reductase in liver,and hormone-sensitive lipase(HSL),and adipose triglyceride lipase(ATGL)in subcutaneous adipose tissue,were measured by real-time PCR.The liver concentrations of triglyceride,reactive oxygen species,and ACCase were measured by ELISA and HSL activity was determined using turbidimetry.Results:NAFLD developed in the CS,HFD,and CS t HFD groups,with the most severe NAFLD being in the CS t HFD group.Serum AST,ALT,and FFA,liver index,and hepatic triglyceride,FFA,and tumor necrosis factor-a were significantly higher in both the CS and CS t HFD groups.However,food intake and ACCase mRNA expression were lower.The mRNA expression of HSL and ATGL in adipose tissue was much higher,and HSL activity was higher in the CS group than in the BC group,and in the CS t HFD group than in the HFD group.Conclusion:We have successfully established two models of stress-induced NAFLD,suggesting stress can induce and aggravate NAFLD by promoting fat mobilization through upregulation of HSL and ATGL. | Jie Mu Xueqian Wang Qingguo Wang Fafeng Cheng Wenxiang Zhu Changxiang Li Chongyang Ma Changming Zhai Yajun Lian Xin Du | 2019 | Journal of Traditional Chinese Medical Sciences2019，6，4： | 2 |

| 5 | Inhibitory Effect of 16 Fungicides on Persimmon Anthracnose Pathogen Colletotrichum horii显示文摘In this research,the inhibitory effect of 16 fungicides on Colletotrichum horri causing persimmon anthracnose was investigated using mycelial growth method and spore germination method. The results showed that among the 16 tested fungicides,10% of Difenoconazole WG,33. 5% of Copper quinolate SC,25%of Bromothalonil EC,70% of Mancozeb WP,430 g/L of Tebuconazole SC,50% of Prochloraz-manganese chloride and 400 g/L of Flusilazole EC achieved the best inhibitory effect on mycelial growth of C. horri,with the inhibition rate of 100%; 70% of Polyram WG,33. 5% of Copper quinolate SC,25% of Bromothalonil EC,70% of Mancozeb WP,50% of Chlorobromoisocyanuric acid AF,50% of Triram WP and 400 g/L of Flusilazole achieved the best inhibitory effect on spore germination of C. horri,with the germination rate of 0. In conclusion,33. 5% of Copper quinolate SC,25% of Bromothalonil EC,70% of Mancozeb WP and 400 g/L of Flusilazole EC achieved the best inhibitory effect both in mycelial growth and spore germination,which could be used as the preference fungicides for the control of persimmon anthracnose,and 70% of Polyram WG and 50% of Triram WP achieved the secondly best inhibitory effect,which could be used as alternative fungicides. The results of this research could provide scientific evidence for the effective control of persimmon anthracnose,and more optional pesticides for utilization in the production practice of persimmon industry. | Xianmei YU Changming HOU Kunpeng ZHANG Hao ZHAI Yanan MA Miao AN Chengxiang AI | 2019 | Agricultural Biotechnology2019，8，1： | 1 |
| 6 | Biological Characteristics of Persimmon Anthracnose Pathogen Colletotrichum horii and Screening of Inhibitory Fungicides显示文摘This experiment studied the biological characteristics of Colletotrichum horii causing persimmon anthracnose using the crossing method and blood cell counting plate method,and screened inhibitory fungicides via assessing the effects of 16 common fungicides on the mycelial growth and spore germination. The results showed that the most suitable temperature for mycelial growth of C. horri is 25℃,the most suitable temperature for spore germination is 28℃; the suitable p H for mycelial growth of C. horri is 4. 0-6. 0,the most suitable p H for spore germination is 4. 0; the optimal carbon source is glucose and maltose,and the optimal source of nitrogen is beef extract. Among the 16 common fungicides,33. 5% copper quinolate SC,25% bromothalonil EC and 70% Mancozeb WP have the optimal inhibitory effects on the mycelial growth and spore germination of C. horri,and can be used as preferred agent for prevention and control of persimmon anthracnose,followed by70% Polyram WG,400 g/L Flusilazole EC and 50% Thiram WP,which can be used as alternative agents. The results are expected to provide experimental basis for effective control of persimmon anthracnose. | Xianmei YU Changming HOU Kunpeng ZHANG Jie WANG Ya'nan MA Hao ZHAI Miao AN Chengxiang AI | 2018 | Asian Agricultural Research2018，10，10： | 0 |
