by University of Maryland School of Medicine When the SARS-CoV-2 protein Nsp6 is made in a fruit fly heart (center), the heart has structural defects compared to a normal heart without the viral protein (left). When fruit fly hearts with the viral Nsp6 protein are given the metabolism changing drug 2DG (right), the hearts begin...
by Bob Yirka, Medical Xpress Cortical thickness atrophy after mild COVID-19 infection. Surface-based morphometry by high-resolution 3T MRI (A). Results from the analysis of 81 subjects with confirmed SARS-CoV-2 diagnosis (who had mild respiratory symptoms and did not require hospitalization or oxygen support) compared with 81 healthy volunteers (without a diagnosis of COVID-19). The analysis...
by Bob Yirka, Medical Xpress SARS-CoV-2 can reach SH-SY5Y neuronal cells from Vero E6 permissive cells. Infected Vero E6 cells (donor cells) were cocultured with SH-SY5Y neuronal cells previously stably transfected with a vector that expresses mCherry (acceptor cells). Coculture was fixed at 24 and 48 hours. (A to G) Confocal micrographs showing 48 hours...
EUROPEAN SOCIETY OF CLINICAL MICROBIOLOGY AND INFECTIOUS DISEASES New data to be presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID 2022, Lisbon, 23-26 April) shows that participants taking the new anti-COVID drug molnupiravir eliminate actively infectious SARS-CoV-2 virus by day 3 of starting therapy, while many participants who received placebo...
by Adrian Esterman, The Conversation Credit: Pixabay/CC0 Public Domain Exactly two years ago, on March 11 2020, the World Health Organization (WHO) declared COVID-19 a global pandemic. This was two months after there were reports of a mystery virus infecting people in Wuhan, the most populous city in central China. Early reports said the virus didn’t appear to...
by Bob Yirka , Medical Xpress Credit: Pixabay/CC0 Public Domain In a study that has not yet been peer-reviewed or accepted for publication, researchers at Bristol University in the U.K. have found evidence that suggests the SARS-CoV-2 virus becomes less infectious within five minutes of exposure to air. The team has published a paper on...
Mathematical simulations show the new approach may offer faster, cheaper, and more accurate detection, including identifying new variants. A novel approach to testing for the presence of the virus that causes Covid-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work,...
