In an article published in the Journal of Applied Physiology, researchers at the University of São Paulo show that damage to small blood vessels in the lungs caused by SARS-CoV-2 is the main factor underlying severe COVID-19. Blood clotting (thrombosis) in the capillary vessels of the lungs is one of the first consequences of severe COVID-19, even preceding the respiratory distress caused by diffuse alveolar damage, according to a Brazilian study reported in an article published in [...]

(MENAFN - IANS) Sao Paulo, Sep 28 (IANS) People who follow vegan diets have low risk of eating disorders, finds a study. The team at University of Sao Paulo (USP) in Brazil used an online questionnaire to collect socio-demographic data (such as education, income and location, among others) and information on eating habits for 971 participants aged 18 or older from all parts of Brazil. Analysing the data, they were able to arrive at the percentage of vegan diet followers reporting [...]

New Delhi, Sep 19 (SocialNews.XYZ) The use of cell therapy to treat COVID-19 patients can reduce the risk of death from the disease by 60 per cent, according to a new study. The systematic review and meta-analysis covered 195 clinical trials of advanced cell therapies targeting COVID-19 that were conducted in 30 countries between January 2020 and December 2021, as well as 26 trials with outcomes published by July 2022. The findings of the study, conducted by researchers at the University [...]

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 Aging. "These findings open the [...]

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 weight gain, high blood sugar, [...]

Brasilia, April 26 (SocialNews.XYZ) Illegal deforestation on indigenous lands in the Brazilian Amazon jumped 129 per cent between 2013 and 2021, a study released by the Sao Paulo Research Foundation revealed. This generated 96 million tonnes of carbon dioxide emissions, with 59 per cent occurring between 2019 and 2021, the study published in the journal "Scientific Reports" detailed. The study analysed 232 indigenous territories and found deforestation in the territories reached [...]

New York, April 18 (IANS) Increased intake of refined rice and wheat as well as processed red meat, and low consumption of whole grains is causing a significant increase in the global cases of diabetes, according to a study.

A 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 analyzed 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 percent of the samples, suggesting this method could be an alternative to the conventional swabbing method, which is [...]

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 airways. On the [...]
