[quick news] 2020 / 2 / 18 chloroquine: an old anti malarial drug with new efficacy

Chloroquine: Zhang Xinmin, director of the biological center of the Ministry of science and technology, an old anti malarial drug, often found new effects, mentioned a drug, chloroquine phosphate, at a press conference The results showed that chloroquine phosphate had a good inhibitory effect on the new coronavirus in vitro "At present, clinical research is being carried out in more than ten hospitals in Beijing and Guangdong, with more than 100 patients enrolled The novel coronavirus pneumonia is also being initiated by Hunan Province in recent years The clinical results show that chloroquine phosphate has certain therapeutic effects on the new crown pneumonia Novel coronavirus infection in China is also under way Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-02/17/content.Htm? Div = - 1 new gene editing tools help to more accurately identify and treat diseased cells researchers from Stanford University recently published a paper in the journal Molecular cells, saying that they have designed a new type of gene editing tool CRISPR CAS gene editing tool can detect and control multiple genetic circuits at a time The researchers said the new technology could help detect cancer more accurately and help eliminate cancer cells The researchers believe that the technology can be used not only to treat cancer and other diseases, but also for other purposes, such as promoting the rapid transformation of stem cells to repair damaged organs Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-02/17/content_439985 HTM? Div = - 1 US media: scientists have found that the largest phage phage is the main driver of ecosystem change because it preys on bacteria, changes their metabolism, spreads antibiotic resistance, and carries compounds that cause disease in animals and humans To learn more about these invaders, researchers searched a DNA database that they created by collecting samples from nearly 30 different environments around the world, according to a statement, interesting science website reported recently From these DNA, they found 351 huge phages, including the largest phage ever found Its genome contains 735000 base pairs, nearly 15 times larger than the average phage Http://www.cankaoxiaoxi.com/science/20200217/2402046.shtml if there is no frog, how will the snake attach? A new study by researchers at the University of Maryland and Michigan State University shows for the first time that the extinction of amphibians has a chain reaction to snakes The paper was recently published in science The results showed that a large number of frogs died after the infection of Botrytis in a remote forest in Panama, accompanied by a sharp decline in the number of snake species, leading to a more homogeneous snake community The study is a wake-up call for the biodiversity crisis or the disappearance of global wildlife Elise Zipkin, a comprehensive biologist at Michigan State University and co-author of the study, said: "some rare or hard to find species may be declining so rapidly that we may never realize that we are losing them In fact, the study focuses more on the widespread loss of biodiversity and its consequences than on snakes " Http://news.scienceet.cn/htmlnews/2020/2/435829.shtm SCI signal: to reveal the mechanism of inflammation determining cell fate, the latest research shows that human inflammation can be controlled by a unique and highly organized receptor, which can "dance" on the cell surface The findings, published in the journal Science Signaling, explain how the process determines whether cells die, reproduce or migrate in the body The team, from the University of reading and the German Research Institute in WITTSBURG, documented how a particular complex arrangement of cell receptors called TNFR1 formed triangles - through a process similar to a dancer's arm holding process http://www.bioon.com/article/6750635.html
