Why old age is a risk factor for Covid-19
Publicado em 14 setembro 2023Sao Paulo, Sep 14 (SocialNews.XYZ) Ageing is known to increase the production of an immune protein that may harmfully react with a person's own tissues or organs. But researchers have now found that Covid-19 infection can exacerbate their production, explaining why old age raises the odds of developing severe Covid. Increases in the immune protein, known as auto-antibodies, may also lead to blood clotting disorders such as thrombosis, showed the study, published in the journal npj [...]ver notícia -
Study finds common sleep hormone pill can worsen bowel inflammation
Publicado em 04 junho 2023Sao Paulo, June 4 (SocialNews.XYZ) - Despite its antioxidant effects and role in regulating sleep cycles, melatonin, popularly known as the "sleep hormone", can worsen inflammation of the intestine and impair the action of gut microbiota, warned a study. The community of bacteria and other microbes in the gut is important to health, helping control digestion and benefiting the immune system. An imbalance of unhealthy and healthy microbes in the intestines may contribute to [...]ver notícia -

Covid virus can be detected in tears sampled by ocular swab: Study
Publicado em 17 fevereiro 2023A team of researchers found that the coronavirus that causes Covid-19 can be detected in tears sampled by ocular swabs, a new study has shown. The researchers analysed samples from patients diagnosed with the disease by conventional methods and admitted to the Hospital, according to the study published in the Journal of Clinical Medicine. SARS-CoV-2 was detected in 18.2 per cent of the samples, suggesting this method could be an alternative to the conventional swabbing method, which is [...]ver notícia -
Gene that naturally protects people against Covid discovered
Publicado em 22 novembro 2022Sao Paulo, Nov 22 (SocialNews.XYZ) 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 [...]ver notícia -
Covid virus alters RNA in infected cells, shows study
Publicado em 10 novembro 2022Sao Paulo, Nov 10 (SocialNews.XYZ) - 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, [...]ver notícia -
How post-Covid loss of smell or taste affects cognition

Scientists use human breast milk to treat prolonged COVID
Publicado em 24 junho 2022Sao Paulo, June 24 (SocialNews.XYZ) 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 [...]ver notícia -
Omicron's mutations explain why it is less severe among vaccinated
Publicado em 09 fevereiro 2022Sao Paulo, Feb 9 (SocialNews.XYZ) 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, [...]ver notícia
