[ad_1] NEW YORK: A team of Chinese researchers identified and mapped SARS-CoV-2 , the virus that caused the Covid-19 pandemic, at least two weeks before the country officially informed the world about the virus, according to media reports. The reports, based on documents from the US department of health and human services (HHS) and shared with a US congressional committee, raise concerns about China transparency on the virus. The congressional investigators said Chinese researcher Lili Ren uploaded an incomplete sequence of the virus's structure to a US government-run database GenBank on Dec 29, 2019, Wall Street Journal reported.Three days later GenBank informed Ren her submission was incomplete and requested that she provide the complete information, Washington Post reported. As Ren did not submit the requested annotations, her submission was deleted from GenBank's processing queue on Jan 16, 2020. A "nearly identical" genetic sequence of SARS-CoV-2 was submi...

[ad_1] People who get COVID-19 but never develop symptoms, known as super dodgers, may have a hereditary advantage. According to a new study headed by UC San Francisco researchers, they are more than twice as likely as individuals who become symptomatic to contain a specific gene variation that aids in virus eradication. The paper, published July, 19, 2023 in Nature, offers the first evidence that there is a genetic basis for asymptomatic SARS-CoV-2. The research helps to solve the mystery of why some people can be infected without ever getting sick from COVID-19. The secret lies with the human leukocyte antigen (HLA), or protein markers that signal the immune system. A mutation in one of the genes coding for HLA appears to help virus-killing T cells identify SARS-CoV-2 and launch a lighting attack. cre Trending Stories Also read: Monitoring T Cells Might Allow Type 1 Diabetes Prevention: Study The T cells of some people who carry this variant can identif...

[ad_1] Scent dogs may represent a cheaper, faster and more effective way to detect Covid-19, than conventional Covid-19 tests such as RT-PCR.  The review, published in Journal of Osteopathic Medicine, found that scent dogs are as effective, or even more effective, and could be a key tool in future pandemics, a new review of recent research suggests.  "Although many people have heard about the exceptional abilities of dogs to help humans, their value to the medical field has been considered fascinating, but not ready for real-world medical use," said Prof. Tommy Dickey from the University of California, Santa Barbara in the US.  cre Trending Stories "Having conducted this review, we believe that scent dogs deserve their place as a serious diagnostic methodology that could be particularly useful during pandemics, potentially as part of rapid health screenings in public spaces. We are confident that scent dogs will be useful in detecting a wide variety of diseas...
