Minks are raised in many countries and have transmitted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans. However, the biologic properties of SARS-CoV-2 in minks are largely unknown. Here, we investigated and found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts, and transmits efficiently in minks via respiratory droplets; pulmonary lesions caused by SARS-CoV-2 in minks are similar to those seen in humans with COVID-19. We further found that a spike protein-based subunit vaccine largely prevented SARS-CoV-2 replication and lung damage caused by SARS-CoV-2 infection in minks. Our study indicates that minks are a useful animal model for evaluating the efficacy of drugs or vaccines against COVID-19 and that vaccination is a potential strategy to prevent minks from transmitting SARS-CoV-2. 相似文献

This article focuses on Chua Beng Huat’s work on the East Asian pop culture that became more prominent in East and Southeast Asia from the 1990s, when the circulation of multilingual and multi-format pop culture started to exceed linguistic, ethnic and national boundaries. It argues that Chua’s work indicates that the pop-cultural production and innovation that support the globalisation and regionalisation processes in East Asia need not be national in origin but can hail from different national origins – and this despite the existing political realities of the region and its history of political fractures. Chua Beng Huat cautions, though, that the national popular can also be marshalled to defeat the border-crossing potential of an inter-Asian pop culture. What is the “Asia” imagined or being represented in such cultural production? Chua’s work is also distinctive in that it deals with the political and economic conditions that underpin mainstream pop consumption as a socio-cultural phenomenon, instead of examining consumption as identity politics. The article concludes by noting the significance that Chua as an institutional builder has played in enabling the study of East Asian pop culture in the region. 相似文献

PPP模式已成为我国公共产品或服务提供的重要方式。PPP 项目的融资性是公私双方合作的关键因素之一。PPP项目中主要合作方的融资目标既有共同点又存在差异点。研究在文献回顾的基础上,依据利益相关理论,分析了我国大型体育场馆政府、社会资本和公众对 PPP项目融资目标的不同诉求和体育场馆融资要素结构,运用多目标规划模型,以重庆市某体育场馆为例对伙伴各方接受的融资性进行方案对比,探讨了假设条件下实现体育场馆PPP项目融资的最佳伙伴合作方式。 相似文献

摘要:目的: 探讨心脏NRG1在间歇运动激活心梗(myocardial infarction,MI)大鼠心肌NRG1-PI3K/Akt通路抑制心肌细胞凋亡的作用。方法:雄性SD大鼠48只,随机分为假手术组(S),心梗安静组(MI),心梗+间歇运动组(ME),心梗+间歇运动+抑制剂组(MEA),每组12只。采用左冠脉前降支结扎法建立MI模型。S组手术仅穿线不结扎。ME组和MEA组在MI术后1wk进行跑台间歇运动。运动开始速度为10m/min运动10min后,速度逐渐增至25m/min×7 min,再以15 m/min×3min运动,之后依次交替进行。60min×1次/d,5d/1wk×8wk。训练结束后次日,腹腔麻醉,颈动脉插管测定LVSP、LVEDP及±dp/dtmax。之后开胸摘取心脏,进行组织学制片,Masson染色。荧光实时定量PCR测定心肌NRG1及其受体ErbB2/4表达。Western Blot法检测心肌NRG1、ErbB2/4、PI3K/Akt、Bcl-2和Bax蛋白含量。Caspase3表达及TUNEL检测观察分析心肌细胞凋亡情况。结果: MI组胶原容积百分比(CVF)和LVEDP较S组显著升高(P<0.01,P<0.01),LVSP和±dp/dtmax显著降低(P<0.01,P<0.01)。且MI后心肌ErbB4 mRNA表达显著降低(P<0.01),心肌NRG1、ErbB2和ErbB4蛋白表达显著降低(P<0.05,P<0.01,P<0.01),PI3K/Akt蛋白表达及Bcl-2/Bax比值显著降低(P<0.01,P<0.01),TUNEL阳性细胞数和Caspase3活力显著增加(P<0.01,P<0.01)。ME组CVF和LVEDP较MI组显著降低(P<0.01,P<0.01),LVSP和±dp/dtmax显著升高(P<0.01,P<0.01),心肌NRG1、ErbB2和ErbB4 mRNA及蛋白表达均显著增加(P<0.01,P<0.01,P<0.01),PI3K/Akt蛋白表达和Bcl-2/Bax比值显著增加(P<0.01,P<0.01),TUNEL阳性细胞数和Caspase3活力显著降低(P<0.01,P<0.01),且运动效应被抑制剂AG1478显著减弱。结论:间歇运动可通过激活心肌NRG1及其受体表达,上调PI3K/Akt蛋白表达,抑制心肌细胞凋亡和胶原过度增生,改善心功能。 相似文献

摘要:应用文献资料法、专家访谈法等研究方法对大型体育场馆融资模式的风险和收益进行研究。研究认为:LBPF融资模式下,大型体育场馆建设最重要的两大问题就是盈利和风险;由于大型体育场馆LBPF融资模式的特性,不确定的因素贯穿于整个项目的实施过程,与此同时,在项目的整个生命周期,对于风险的识别工作也应连续、动态地开展,其所有风险因素可分成宏观、中观、微观;在LBPF融资模式下,大型体育场馆项目的风险分担原则是:在保证项目经济平衡的前提下,考量各风险承担方(政府和经营伙伴)的风险承担及管理能力,并根据承担能力来分配项目风险;在大型体育场馆的策划决策阶段,面临的最重要任务是投融资,有关主体之间的博弈主要是政府部门和社会投资方之间的二者博弈。 相似文献

ABSTRACTIn this article, I question practice as a research paradigm by exploring its position in relation to non-positivist qualitative methodologies. Frayling’s [1994. Research in art and design. Royal College of Art Research Papers, 1(1), 1993/4] distinctions between research into, through, and as (for) practice are expanded to explore overlaps between these approaches. I argue for the need to understand the nuances of different epistemologies and ontologies that underpin diverse disciplinary approaches to practice-research. This is done through an analysis of a selection of Arts and Humanities Research Council (AHRC)-funded projects to find out how they are using and/or embedding practice in the research process. The resulting Colour Wheel of Practice-Research illustrates a spectrum of positions of practice in relation to research, suggesting existing research paradigms are bursting at the seams and that the “disciplinary matrix” of practice might offers other ways of knowing. The reason I have chosen to focus primarily on AHRC-funded projects is because it explicitly states its support of “practice-led research” and that it “remains dedicated to this area of research”. This article aims to add to knowledge of how and why practice-research is of continuing interest to research councils, universities, and those identifying as practice-based/led researchers. 相似文献

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.
Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264
The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage. 相似文献
