Sao Paulo, Nov 22 (IANS) 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 [...]

Sao Paulo, Feb 9 (IANS) Brazilian researchers have found that Omicron has mutations detected in previous variants and that is the reason why it is less severe among the vaccinated. Omicron emerged as a variant of concern only in November 2021, but all the mutations it contains, except one, had been described before that. Researchers at the Federal University of Sao Paulo (UNIFESP) in Brazil attribute this factor to the effectiveness of the existing vaccines against the variant, reflected [...]

Sao Paulo, Jan 28 (IANS) 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. The patients were followed until they tested negative twice or three times consecutively by RT-PCR. Of the 38 cases tracked, two men and a woman [...]

Sao Paulo, July 7 (IANS) Brazilian researchers have found that tissues which specialise in saliva production and secretion can serve as reservoirs for SARS-CoV-2, the virus causing Covid-19, magnifying its infectious potential. Researchers at the University of Sao Paulo (USP) analysed samples from three types of salivary gland obtained during a minimally invasive autopsy procedure performed on 24 patients who died from complications of Covid-19 and discovered that SARS-CoV-2 infects and [...]

Sao Paulo, June 4 (IANS) 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 [...]

Sao Paulo, May 19 (IANS) - People who have had dengue in the past are twice as likely to develop symptoms of Covid-19 if they are infected by coronavirus, finds a new study. The study, led by University of Sao Paulo in Brazil, detected the presence of antibodies against dengue virus and SARS-CoV-2 in blood samples from 1,285 inhabitants of Mancio Lima, a small town in the state of Acre, part of Brazil’s Amazon region. “Our results show that the populations most exposed to dengue, [...]

Sao Paulo, Apr 24 (IANS): Scientists now report that a high dose of vitamin D administered on admission to hospital has failed to improve the condition of patients with moderate or severe Covid-19.
