Study on Developmental Expression of ApoCⅡ Gene mRNA in Liver Tissues of Pigs     

LIU Cui-cui  GUO Xiao-hong  CAO Guo-qing  GAO Peng-fei  PU Zhong-de  NIU Jiao-yan  ZHANG Qi  LI Meng  JIN Yu-shu  LI Bu-gao 《中国畜牧兽医》2015,42(10):2726-2731

The aim of this study was to investigate the developmental patterns of ApoCⅡ gene mRNA in liver in Mashen and Large White pigs, and study the relationship between the expression level of ApoCⅡ and the lipid metabolism in pigs.The mRNA relative expressions of ApoCⅡ gene in liver at seven stages of 1,30,60,90,120,150,and 180-day old in Mashen and Large White pigs were determined by quantitative Real-time PCR.The results showed that the developmental trend of ApoCⅡ mRNA expression in liver between Mashen and Large White pigs was different.The ApoCⅡ mRNA abundance was decreased from birth to 60-day old,then increased at 90-day old,and decreased again after that in Mashen pig.However,the relative expression amount in Large White pig was gradually decreased from birth to 150-day old and increased again at 180-day old.Except for the ApoCⅡ mRNA expression amount at 1-day old,the differences of the expression amount at other stages in Mashen and Large White pigs were significant or extremely significant (P<0.05 or P<0.01).The ApoCⅡ mRNA expression in liver was affected by age and breed,and could play an important role in lipid metabolism in pigs.  相似文献

Effects of Addition of Three Types of Biochar on the Soil Nitrogen Balance and Cotton Yield   总被引：1，自引：1，他引：0  

Huang Ting  Ni Jieqiang  Xu wenxia  Zhai Yong  Ye Jun  Hou Zhen’an 《棉花学报》2015,27(6):595-600

The objective of this study was to determine the effect of biochar addition on the soil N balance and cotton yield in a drip-irrigated cotton field. The experiment included four soil amendments: control, cotton straw biochar, corn cob biochar, and poultry manure biochar. The biochar was applied at a rate of 4.5 t·hm^－2 except control. The results showed that all three types of biochar significantly reduced both the apparent soil N loss and the N surplus. The effect of cotton straw biochar treatment was most significant, relative to the control. Plant nitrogen uptake differed significantly between the different treatments, decreasing in the order cotton straw biochar > poultry manure biochar > corn cob biochar. Cotton yield also differed significantly between the different treatments, decreasing in the order poultry manure biochar > corn cob biochar, and cotton straw biochar.  相似文献   

Hull-White利率模型仿真与债券估值     

陈勇  邓坤 《湖南农业大学学报(自然科学版)》2015,(4):12-15

由于“中”“庸”两词语义上的模糊性，其哲学含义颇为复杂。从郑玄到二程、吕祖谦，尤其是朱熹，都对“中庸”进行了解释，现代学者对《中庸》书名的释义更是多种多样。对于《中庸》的时代以及与子思的关系问题，中国历代学者以及西方的汉学家都提出了不同的观点，至今仍然莫衷一是。  相似文献

双波长HPLC同时测定氮沉降处理下杜仲皮和叶中的5种成分     

哀建国  杜江丽  周爱存  金松恒  宋新章 《浙江农林大学学报》2015,(1):60-66

建立双波长高效液相色谱法(HPLC)同时测定模拟氮沉降处理下杜仲Eucommia uimoides皮和叶中松脂醇二葡萄糖苷、桃叶珊瑚苷、绿原酸、京尼平苷酸和京尼平苷等5种活性成分含量的方法。采用Agilent ZORBAX SB-C18柱(250.0 mm×4.6 mm,5μm),以乙腈(A)-2.0 g·kg-1磷酸水溶液(B)进行梯度洗脱(0~12 min,10%A;12~25 min,13%A;25~50 min,30%A;50~65 min,60%A);流速为0.8 m L·min-1;检测波长203 nm,240 nm;柱温30℃。结果表明:松脂醇二葡萄糖苷、桃叶珊瑚苷、绿原酸、京尼平苷酸、京尼平苷等在各自的线性范围内与其峰面积积分值呈良好的线性关系。整个实验期间,杜仲皮和叶中5种成分含量对施氮处理产生了不同的响应,且随季节在变动。该方法能准确、快速地对杜仲皮和叶中多种有效成分同时进行测定,可较好反映浙江高氮沉降区特色名贵药材杜仲皮和叶中多种有效成分的变化。  相似文献
