Sao Paulo– A team of Brazilian researchers has discovered that a gene can protect people, even those aged 90 and above, from the deadly Covid disease. Two research papers found that the frequency of variants of the gene ‘MUC22’ was twice as high in the mild Covid-19 group as in severe patients, and higher still in resilient super-agers. This gene belongs to the “mucin” family and is associated with the production of mucus, which lubricates and protects the [...]

Sao Paulo– For the first time, scientists have shown that infection by Covid virus changes the functioning of host cell RNA, providing clues as to how different variants can escape the immune system, and serve as a basis for the development of novel treatments. Researchers at Federal University of Sao Paulo (UNIFESP) in Brazil arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA. The study, published in Frontiers [...]

Sao Paulo– In a rare case, Brazilian scientists used breast milk to treat Covid-19 in a woman with a rare genetic disease that makes her immune system unable to combat viruses and other pathogens. The patient who was diagnosed with Covid-19, in March 2021, tested positive for 124 days by RT-PCR. She was advised by the team from the University of Campinas (UNICAMP) in Sao Paulo, to take 30 millilitres of breast milk every three hours for a week. The breast milk was donated by a [...]

Sao Paulo, Jan 28 : A team of international researchers have found that the novel Coronavirus can continue to be present in some human bodies upto 232 days. Researchers from France’s Pasteur Institute, the University of Sao Paulo (USP) and Oswaldo Cruz Foundation (Fiocruz) in Brazil conducted a study involving 38 Brazilian patients.

Sao Paulo– People with dementia, particularly Alzheimer’s disease are at threefold risk of dying as a result of infection by SARS-CoV-2, the virus behind Covid-19, according to a study by Brazilian researchers. The risk is six times greater if they are over 80, found the team at the University of Sao Paulo (USP) and Butantan Institute in partnership with colleagues at the Federal University of Rio de Janeiro (UFRJ). “We found that all causes of dementia are risk factors for [...]
