[news] 2020/2/6 novel coronet, new novel coronavirus pneumonia patients have higher viral nucleic acid levels in the early stage.

Novel coronavirus, a novel coronavirus pneumonia, has been published in the preprint website of the Wuhan Institute of viral diseases, China Academy of Sciences, Shi Zhengli The new identification of the new coronavirus that causes the epidemic of pneumonia in Wuhan is published This paper reveals the basic biological characteristics of the coronavirus from the aspects of nucleic acid detection, serological diagnosis, virus isolation and receptor utilization, which provides important clues for epidemic control and drug research and development It is worth noting that the scientific research team carried out two rounds of nucleic acid detection on the samples of bronchoalveolar lavage fluid, pharyngeal swab and anal swab in different periods of patients, the time was December 30, 2019 and January 10, 2020, respectively The results showed that the amount of viral nucleic acid in the previous period was about 1000 times higher than that in the later period Http://www.zhishifenzi.com/news/biology/8193.html the mystery of human metapneumovirus (hMPV) has opened a new study in the United States It has been found that the m6A modification of human metapneumovirus (hMPV) can help the virus hide successfully and not be found by the immune system, thus promoting the replication and gene expression of hMPV Animal experiments show that the experimental hMPV vaccine targeted at m6A can induce strong innate immune response and effective adaptive response, and then prevent lung and nasal infection Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-02/05/content_439512.htm? Div = - 1 the triangular structure between bacteria protects the human mouth from actinomycete infection Kunming Institute of zoology, Chinese Academy of Sciences found that sclerecta and Bacteroides have a triangle structure of synergistic inhibition of actinomycetes, and this functional group exists in both the intestine and the mouth, but its structure and function in the intestine and the mouth are very different In the research, they also put forward an important idea, that is, using complex network analysis method to mine functional groups in microbial community Through this method, we can explore the interaction between species in the community Li Wendi and others use complex network analysis to get the interaction between species, and then reverse search for the possible functional groups in the flora Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-02/05/content_439486.htm? Div = - 1 foreign media: American experts think it's unnecessary to worry about the spread of virus in express packages According to the daily mail of the UK, federal health agencies and infectious disease experts in the United States say the virus will not survive for long on post parcels, and that human to human transmission is much more likely than infection from the surface of objects The U.S Centers for Disease Control and Prevention (CDC) explained on its website that there is little chance of coronavirus infection through the surface of objects Packages go through different environments before they arrive, which makes the virus less likely to survive In addition, Elizabeth McGraw, director of the center for infectious dynamics at Pennsylvania State University, said cartons were not a good place for virus breeding Http://www.cankaoxiaoxi.com/science/20200205/2401334.shtml the University of science and technology of China has made progress in the field of anti-tumor ultrasound dynamic sensitizer, China University of science and technology, 5 news: researchers at the University found a material that can be used as a source of ultrasound dynamic sensitizer, which is helpful for clinical use of ultrasound dynamic therapy to remove tumor cells In this work, the black phosphorus nano sheet is used as the model piezoelectric material It is proved that the piezoelectric material with appropriate energy level structure can generate active oxygen substances under ultrasound conditions, thus achieving the responsive removal of tumor cells These experimental results show that the piezoelectric material can be used as an ultrasonic dynamic sensitizer, and show the research value of such a new ultrasonic dynamic sensitization mechanism in the biomedical field http://www.chinanews.com/sh/2020/02-05/9079634.shtml
