为检测秦皇岛市昌黎县某渔场养殖的致半滑舌鳎烂尾病的致病原,检测分离菌对抗生素的敏感性以及中草药对其的体外抑菌效果,本研究从患病鱼尾部肌肉分离纯化到一株细菌,采用TCBS鉴定培养基培养,结果可见绿色菌落,边缘整齐,表面光滑,轻微凸起;经革兰氏染色后镜检可见,分离菌为革兰氏阴性菌,两端钝圆,形状似月牙;经ATB全自动微生物鉴定仪判定,分离菌为创伤弧菌,符合率为99%;通过16S rDNA序列分析进一步鉴定分离菌为创伤弧菌,命名为CLVV-1。采用动物回归试验检测分离菌株的致病性,结果显示CLVV-1菌株可致半

为制备杆状病毒表达系统表达的番鸭源鹅细小病毒(MDGPV)VP2蛋白形成的病毒样颗粒(VLPs),并测定其免疫原性,本研究通过PCR扩增得到MDGPV PT株VP2基因,通过杆状病毒表达系统构建了表达MDGPV VP2的重组杆状病毒MDGPV-rBV。以MOI 5的MDGPV-rBV感染Sf9细胞后,通过间接免疫荧光试验(IFA)检测结果显示,MDGPV-rBV感染的细胞出现亮绿色荧光;western blot检测VP2蛋白,结果显示在约65 ku处出现特异性条带,表明VP2蛋白正确表达。收集MDGPV-
A visible light-promoted reaction of donor/acceptor diazoalkanes with sulfoxides towards the synthesis of synthetically useful sulfoxonium ylides was reported.The reaction occurred under sole visible light irradiation without the need of any transition-me

MicroRNAs(miRNAs),especially exosomal miRNAs,are promising noninvasive biomarkers in early-stage cancer diagnosis and disease treatment monitoring.However,their precise and sensitive quantification remains challenging due to their small size and low abund
A complex community of human-associated microorganisms plays diversely important roles in maintaining health,and the metabolites help to define whether a particular human-associated microbe is a friend or a foe.This work shows that Aspergillus brunneoviol
文章基于中国综合社会调查CGSS2015的相关数据,选取社会治理和社会地位作为解释变量,选取社会公平感知作为被解释变量,运用二元分类Logit回归模型依次测度各自变量对社会公平感知的影响效应。结果表明:社会治理对社会公平感知具有显著正向影响。在考虑控制变量的条件下,每增加1个单位的社会治理,社会公平感知能够提升83.9%;社会地位对社会公平感知具有显著正向效应,在考虑控制变量的条件下,社会地位每提升1个层次,个体的社会公平感知就提高66.7%。因此,应当重视社会治理,提升社会治理层次与质量,同时尊重地位差
