Abstract: 为研究禽细胞因子il-2与ibdv主要保护性抗原vp2基因融合蛋白的免疫学特性,将重组的rvp2-il-2融合蛋白免疫鸡,通过ibdv-vp2elisa抗体效价、抗体亚型(igg1和igg2a)、淋巴细胞增殖、inf-γ和il-4细胞因子的分泌水平、中和抗体以及动物攻毒试验检测评价其对鸡体免疫水平的影响。抗体滴度测定和淋巴细胞增殖试验结果显示,rvp2-il-2融合蛋白免疫鸡体的体液和细胞免疫应答水平均明显高于单独的vp2蛋白免疫组。抗体亚型测定结果显示,rvp2-il-2融合蛋白免疫组鸡体能产生一个平衡的igg1和igg2a抗体反应。细胞因子elisa试验结果表明rvp2-il-2融合蛋白能有效平衡th1(?-ifn)和th2(il-4)类型的细胞免疫反应。动物攻毒试验rvp2-il-2融合蛋白免疫组鸡体获得了85%的保护率,表明构建的rvp2-il-2融合蛋白对ibdv的攻击具有较好的免疫保护作用。本研究为进一步研制ibd高效的基因工程疫苗奠定了基础。

Abstract: In order to research immunogenicity of the recombinant rVP2-IL-2 fusion protein,we obtained the rVP2-IL-2 fusion protein using Pichia pastoris expression system,and then evaluated its potential to induce immune responses in chicken.The effect was determined in the form of protective anti-IBDV VP2 titers,antibodies(IgG1 and IgG2a),lymphocyte proliferation,the levels of interferon-7 and interleukin-4 cytokines,and challenge experiment.Antibody titers and proliferation lymphocyte level suggested that the fusion protein could elicit specific humoral immune and cellular immune responses.antibody sub-type results indicated that the rVP2-IL-2 fusion protein induced secretion both of IgGl and IgG2a.The seem result elicited from cytokines ELISA test,secretion of both ofThl(γ-IFN)and Th2(IL-4)were induced by the rVP2-IL-2 fusion protein.Challenge experiment result shown that chicken immunized the rVP2-IL-2 fusion protein obtained 85%protection.These results confirm that the fusion protein enhances the protection against IBDV through both humoral and cell-mediated immunity,and thus could Sgl"Ve as a candidate for the development of IBDV subunit vaccine.

地质与勘探 , 1974,
Abstract: 在深孔钻进中,当孔深超过500米以后升降钻具时,由于刹车带与升降机制圈的剧烈摩擦,使升降机发热.升降机发热后,内部润滑油变稀而甩出,不仅影响零件的润滑,有时还可能烫伤人.闸带发热以后,往

Abstract: 摘要:【目的】本研究通过百日咳杆菌黏附素(PRN)基因的分段克隆表达及其在BALB/c小鼠的主动和被动免疫保护试验筛选PRN中的保护性抗原肽。【方法和结果】利用大肠杆菌进行PRN的完整蛋白、N端和C端多肽及其RI和RII区域多肽(双拷贝)的表达,命名为GST-PRN、GST-PN、GST-PC、GST-2PRI和GST-2PRII。Western blot检测证实5种表达产物均具有良好的反应原性。在主动免疫保护试验中,5种表达产物均能诱导小鼠产生较高的PRN抗体水平;当使用3 LD50的支气管败血波氏杆菌
基于生灭过程的城市道路通行能力研究
Capacity Study of Urban Road Based on Birth and Death Processes
 [PDF]

,
Advances in Applied Mathematics (AAM) , 2016, DOI: 10.12677/AAM.2016.54085
Abstract: 首先利用折线图和拟合分析,研究了车道被占用时道路通行能力的变化过程,接着利用交通流模型定量地分析了不同车道被占用道路通行能力的差异,然后对车辆到达率进行了K-S检验,结果显示符合泊松分布,最后利用生灭过程建立车辆排队长度、排队时间和道路通行能力的关系模型。
Firstly, the changing process of the road traffic capacity is studied by using the Line Graph and the Fitting analysis. Then, the Q-V-K model is used to quantitatively analyze the difference of the capacity of the road when different lanes are occupied. In addition, the vehicle arrival rate was tested by K-S test, and the results show that it obeys the Poisson distribution. At last, the model of the relationship among vehicle queue length, queuing time and road traffic capacity is established by using the Birth and Death process.

NiAl合金的高温形状记忆效应

金属学报 , 1994,
Abstract: 观察到Ni-34.6at.-%Al薄带单程和双程形状记忆效应(SME),单程SME发生在300℃以上并具有很好的形状恢复率(100%)。经高温退火后合金中产生了体积分数为16%的延性γ′-Ni_3Al沉淀相、延性和韧性有进一步改善,同时发现退火后的薄带也具有良好的单程和双程高温SME。结果表明富Ni的NiAl有可能成为新型高温形状记忆合金(SMA)。
株洲市社会食品质量安全意识现状及应对策略

湖南工业大学学报(社会科学版) , 2010,
Abstract: 对株洲市社会食品质量安全现状及消费者、经销商和市场管理人员食品质量安全意识的调查和样本分析表明,该地区消费者、经销商及管理者的食品质量安全意识正在逐年加强,整体的食品质量安全状况在“创卫”后也有了很大改观,但目前仍然存在许多亟待政府解决的问题。政府应当加大宣传力度,进一步提高市民食品质量安全意识,同时采取有效措施提高株洲整体食品质量安全水平。
