单核细胞增多性李斯特菌RsbR抗酸应激机制（英文）

目的:探明单增李斯特菌RsbR的两个保守磷酸化位点是否影响SigB(sigmaB)的表达.创新点:解析了RsbR在单增李斯特菌中SigB网络调控中的作用.方法:通过基因缺失、定点突变和回补技术构建rsbR基因缺失株、回补株和回补突变菌株,进行酸应激条件下的生长能力和强酸条件下的存活能力试验,并检测在酸应激下菌株中的SigB基因和蛋白表达的改变情况.结论:RsbR缺失能够显著降低单增李斯特菌的抗酸应激能力和下调SigB表达,RsbR-175位点是SigB调控途径中RsbT释放的先决条件.     

Decoding effects of psychoactive drugs in a high-dimensional space of eye movements in monkeys

Oculomotor behavior has been shown to be correlated with mental disorders in clinics, making it promising for disease diagnosis. Here we developed a thorough oculomotor test toolkit, involving saccade, smooth pursuit, and fixation, allowing the examination of multiple oculomotor parameters in monkey models induced by psychoactive drugs. Eye movements were recorded after daily injections of phencyclidine(PCP)(3.0 mg/kg), ketamine(0.8 mg/kg) or controlled saline in two macaque monkeys. Both drugs ...     

Machine learning-aided atomic structure identification of interfacial ionic hydrates from AFM imagesOA

Relevant to broad applied fields and natural processes,interfacial ionic hydrates have been widely studied by using ultrahigh-resolution atomic force microscopy(AFM).However,the complex relationship between the AFM signal and the investigated system makes it difficult to determine the atomic structure of such a complex system from AFM images alone.Using machine learning,we achieved precise identification of the atomic structures of interfacial water/ionic hydrates based on AFM images,including t...

邀你走近图书盛宴——绘本

读第一遍的时候,你会觉得那是一个有趣或是感人的故事;读第二遍的时候,你会开始思考其中的深意。一遍又一遍地读,都会有不同的感受和领悟,真的是值得一看再看,这就是绘本。绘本的文字少了一份华丽,少了一份雕琢,扑面而来的是清新和通透。但就是在简洁的文字背后,却有着所有文学作品所共有的主题:生命、爱、时间等等。读罢,对于这些问题曾有的迷惘与迷惑似乎都能得到或多或少成都电子科技大学附属实验小学     

A case study of imported pulmonary coccidioidomycosis

Coccidioidomycosis is an endemic disease of the Western hemisphere. The cases in non-endemic areas are mostly imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis, especially for cases occurring in a non-endemic area. In this study, a 71-year-old Chinese male presented to our hospital with chronic cough and malaise, and was found to have a mass in the middle lobe of right lung. He had been visiting Arizona, USA for four months before admission. Pulmonary coccidioidomycosis was confirmed by the results of histopathological examination after lobectomy. Typical microscopic features of Coccidioides are definitely diagnostic, but need be differentiated from other budding yeast infection or carcinoma histopathologically.     

文化图式对英语学习者自主学习的影响

自主学习英语能力缺乏严重影响着大学生英语语言能力的提高。自主学习能力很大程度上受学习者文化知识尤其是文化图式的影响。文化图式作为使个体储存文化信息以及理解文化经历及表达的概念框架,可用来激发学习者主体性,从而达到帮助认知、改进自主学习方法、提高跨文化交际能力的作用。

Superconductivity in One-atomic-layer Metal Films

Superconductivity is a peculiar quantum phenomenon which originates from the pairing of conduction electrons, followed by phase coherent condensation. Since the discovery by K. Onnes in 1911, superconductivity has been one of the hottest topics in physics for an entire century, and still attracts people’s great interest. One of the intriguing issues is how
