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 study. The study, published in the Journal of Applied Physiology, described autopsies of nine patients who died after developing the severe form of the disease showed a clearly typified condition involving alterations to lung vascularisation and thrombosis. For the first time, the [...]

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 [...]

New Delhi, April 18 - Poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing over 70 per cent of new diagnoses globally, according to a study. Of the 30 most populated countries studied, India, Nigeria, and Ethiopia had the fewest case of type 2 diabetes related to unhealthy eating, the researchers said. The analysis, published in the journal Nature Medicine, looked at data from 1990 and 2018, providing valuable insight into which dietary factors are [...]

The findings are published in the journal Language Resources and Evaluation. While there are multiple studies involving natural language processing (NLP) focussed on depression, anxiety and bipolar disorder, most of these analysed English texts and did not match Brazilians' profiles, the researchers said. The first step in this study involved constructing a database, called SetembroBR, of information relating to a corpus of 47 million publicly posted Portuguese texts and the network [...]

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 [...]

Scientists have uncovered a new mechanism that could help explain why some Covid infected people develop a potentially fatal systemic inflammation, according to a study. Researchers at the University of Sao Paulo (USP) in Brazil have found that severe COVID-19 is associated with an imbalance in an important immune system signalling pathway. The researchers detected "dysregulation", or a dysfunctional regulation, of the immune system mediated by adenosine triphosphate (ATP), one [...]

Washington: Scientists have shown for the first time that infection by SARS-CoV-2 changes the functioning of host cell RNA, according to a study. The scientists at the Federal University of Sao Paulo (UNIFESP), Brazil, arrived at this conclusion by analysing thirteen datasets obtained during four studies of viral, human and animal cell RNA. RNA in a cell, or ribonucleic acid, just like DNA, stores genetic information. RNA transmits genetic information from DNA to the cytoplasm, the [...]

Some people infected with SARS-CoV-2 may be able to transmit the virus for longer than the recommended quarantine period, without necessarily manifesting any symptoms during the final stage of the infection, a study suggests. The research, published recently in the journal Frontiers in Medicine, involved 38 Brazilian patients who were followed on a weekly basis between April and November 2020. The researchers affiliated with the Pasteur-USP Scientific Platform, a partnership between [...]

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 were atypical in the sense [...]
