by The University of Hong Kong Figure 1. Intranasal inoculation of SARS-CoV-2 causes acute testicular damage in golden Syrian hamsters A. Schema of intranasal challenge of male Syrian hamsters at 8–10 weeks of age. The animals were randomly divided into groups and intranasally challenged by SARS-CoV-2 HK-13 strain at a dose of 10, 102, 103 and...

(A), highly selective sigma-2 receptor agonist CM398 is shown as posed by AutoDock Vina to a model of the human sigma-2 receptor. (B), dual sigma-1 and sigma-2 receptor ligand AZ66 is shown as posed by molecular docking....

by Purdue University The virus that caused COVID-19 likely does not integrate its genetic material into the human genome, research says. Although throughout human history there have been viruses capable of integrating their genetic material into human genes, this new study found that the COVID-19 virus, which is known to scientists as SARS-CoV-2, lacks the molecular machinery to...

Credit: Worcester Polytechnic Institute A team of researchers that includes Worcester Polytechnic Institute Biology Professor Pamela Weathers has found that extracts from the leaves of the Artemisia annua plant, a medicinal herb also known as sweet wormwood, inhibit the replication of the SARS-CoV-2 virus and two of its recent variants. The team,...
By Guy Faulconbridge CAMBRIDGE, England (Reuters) – Regular booster vaccines against the novel coronavirus will be needed because of mutations that make it more transmissible and better able to evade human immunity, the head of Britain’s effort to sequence the virus’s genomes told Reuters.and as a result, regular booster The novel coronavirus, which has killed 2.65...
