从广东省以及海南省等地区养殖的患病罗非鱼体内分离、收集到多株致病菌,经生化分析和分子生物学鉴定,均为无乳链球菌。对这些菌株分别进行了耐药谱测定、分子分型试验以及分子血清型分析。药敏试验结果表明,2007—2010年分离到的无乳链球菌耐药谱基本相似;多位点可变数目串联重复序列分析(MLVA)试验中,选择5个高变异指数的可变数目重复位点(VNTR)进行分子分型,结果表明,所有鱼源无乳链球菌菌株为同一MLVA型,而作为对照的牛源无乳链球菌则明显不同;为了对这些菌株进一步分型 ...

Abstract Narratives play an essential role in fast‐paced policy making that occurs during crises. The COVID‐19 pandemic brought numerous disruptions of normality, including school closures, which were intensely debated in narratives by many policy actors. Two shutdowns of New York City's public school system affected over 1.1 million students.

The establishment of Elispot-based neutralization assay for HCMV and its application in epidemiological study [PDF]
人巨细胞病毒(humancytomegalovirus,HCMV)的感染在全球普遍存在。HCMV感染一般以潜伏状态存在,当机体免疫力低下时,则易发生再激发感染,引起严重甚至威胁生命的感染性疾病。在自然感染过程中,HCMV可感染包括淋巴细胞,上皮细胞以及内皮细胞在内的多种类型的细胞。HCMV体外培养体系的宿主细胞主要是上皮细胞及成纤维细胞。传统的基于细胞病变的TCID50以及空斑形成减少实验检测样本中和滴度的方法,存在周期长,操作繁杂,主观因素影响大的缺点,不适合大样本量的临床研究 ...

Policy instruments attitudes and support for government responses against Covid‐19
Abstract An individual's political attitudes have been documented as the most important predictor of acceptance of government measures against the COVID‐19 pandemic. Their effect, however, is somewhat unclear and cannot be reduced to one dimension. In this article, we test whether general attitudes toward policy instruments might, together with left ...

Anatomic and radiograph study of anterior cruciate ligament reconstruction [PDF]
目的:1、观察膝关节交叉韧带股骨附着处的解剖形态学特点,并利用PhotoshopCC2014软件测量股骨附着处印迹的实际面积大小;2、研究标准膝关节侧位X线片上前交叉韧带(ACL)股骨止点的相关骨性标志数据,为临床上ACL双束解剖重建提供参考。 方法:对10例成人膝关节标本进行解剖,剔除膝关节标本周围肌肉、关节囊,把髌韧带从股骨端切断,保留髌骨、髌韧带、内外侧副韧带、前后交叉韧带及内外侧半月板,经髁间窝前出口最高点沿矢状面在股骨前面和后面作两条平行股骨纵轴的直线,用手锯沿两直线将股骨分为两部分 ...

目的 了解长春市儿童下呼吸感染病原学特征及其分布规律,为本地区儿童下呼吸道感染的临床治疗提供的参考依据。方法 采用Realtime PCR方法对2018年12月至2019年11月份采集的73份儿童支气管肺泡灌洗液标本进行28种病原及亚型检测。结果 儿童下呼吸道感染中非典型病原体以支原体为主,病毒病原以呼吸道腺病毒、EB病毒、副流感病毒以主,细菌病原感染以流感嗜血杆菌为主。不同的病原体表现不同的流行期。结论 通过对长春市儿童下呼吸道感染进行多病原检测,掌握病原流行特点,不同季节的呼吸道病原谱不一致。

Cyclin Dependent Kinase 5 promotes invasion and metastasis of Hepatocellular Carcinoma [PDF]
肝细胞癌(HepatocellularCarcinoma,HCC)在所有恶性肿瘤导致的死亡原因中占第三位,其发病率居恶性肿瘤的第六位。肝癌具有的高复发以及高转移,使肝癌愈后很差,而导致肝癌高复发和高转移的机制还不是很清楚。最近研究表明细胞周期蛋白激酶家族蛋白在上述调控过程中具有重要作用。 细胞周期素依赖蛋白激酶家族中的一个特殊蛋白:细胞周期素依赖蛋白激酶5(CyclinDependentKinase5,CDK5)引起了我们的注意,CDK5被认为主要在神经系统发挥作用。但是 ...
