[news] novel coronavirus pneumonia prediction by 2020/2/20: new crown pneumonia outbreak or top 2 mid month

Novel coronavirus pneumonia: China's new crown pneumonia outbreak or the peak in mid 2 months, a team from the University of London School of hygiene and tropical medicine, this week predicted that the peak of the epidemic in China's city of Wuhan, the center of the epidemic, could come in mid and late 2 Adam kuhalski, a member of the team, said: "of course, there are still many uncertainties about when and how large the peak will be." This has led scientists to notice so-called "weak signals" that may play an important role in determining the accuracy of the model, Barnes said Http:// Russia has developed a research team led by Igor aznariyan, President of Russian Association of ophthalmologists and doctor of medicine, which can restore stereoscopic vision for different categories of patients with eye diseases More importantly, this kind of "electronic glasses" can help children with congenital defects to restore stereoscopic vision In explaining the working mechanism of the electronic glasses, Igor aznariyan said that the electronic glasses can stimulate brain neurons and stimulate the recovery of binocular optic reflex, that is, to aim the optic axis at the target He also said that wearing such glasses for one hour a day can restore vision within one to six months after treatment The researchers believe that the efficacy can reach 95% Http://digitalpaper.stdaily.com/http_ Div = - 1 novel silver catalytic synthesis method to assist in the research of antitumor drugs Recently, Yunnan University and the research team of Xi'an Jiaotong University have developed a novel silver catalytic synthesis method, which can efficiently and accurately synthesize a series of multi substituted pyrrole compounds with various structures This strategy is of great significance for the efficient synthesis of the antitumor alkaloid lamellarin L In addition, compared with the reported data of total synthesis literature, the new research path not only shortens the synthesis step of the antitumor alkaloid, but also improves the overall reaction yield The research results were published online in ACS catalysis, a top journal in the field of catalysis Http://digitalpaper.stdaily.com/http_ Div = - 1 science sub Journal: receptor targeted nanoparticle therapy for primary and metastatic breast cancer researchers from the University of Maryland School of medicine and other units recently developed a therapeutic nanoparticle Therapeutic platform, which balances receptor specific binding affinity on cell surface while maintaining minimal interaction with blood and tumor tissue components (known as dart nanoparticles), thereby improving blood circulation time, biological distribution and tumor Cell specific uptake of these results provides new ideas for the effective development of therapeutic nanoparticles and evidence for the continued development of dart platform for primary and metastatic tumors Http://news.bioon.com/article/6750740.html new research draws the 3D atomic structure of paramyxovirus, which helps the US research team to draw the 3D atomic structure of a key enzyme of paramyxovirus for the first time, and can help develop antiviral drugs including anti coronavirus drugs The research results were published in the Journal of the American Academy of Sciences Researchers at Northwestern University used frozen electron microscopy to observe the inside of the molecule, captured hundreds of thousands of 2D images of human parainfluenza 5 polymerase, and reconstructed the 3D atomic structure of the enzyme using computer algorithm Http://
