Tea has been renowned globally for its many health benefits, and Malak Esseili, a virologist with the University of...
By Dr. Sanchari Sinha Dutta, Ph.D.Jan 23 2024Reviewed by Benedette Cuffari, M.Sc. In a recent study published on the medRxiv* preprint server, researchers conducted blood digital transcriptomics to determine the persistence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ribonucleic acid (RNA) in patients living with long-term consequences of coronavirus disease 2019 (COVID-19). Study: Blood...

by Lancet Credit: Pixabay/CC0 Public Domain Taking a two-week course of metformin, a safe and affordable diabetes medication after testing positive for SARS-CoV-2 leads to 40% fewer long COVID diagnoses over the following 10 months, compared to individuals taking a placebo, finds a new study published in The Lancet Infectious Diseases journal. The long-term symptoms some people experience...
by Anne Trafton, Massachusetts Institute of Technology Graphical abstract. Credit: ACS Central Science (2023). DOI: 10.1021/acscentsci.2c01471 Antibodies that can disarm a virus, known as neutralizing antibodies, are key to the body’s ability to fight off infection. MIT chemists have come up with a new way to identify these neutralizing antibodies in a blood sample, by analyzing how antibodies...
by The Scripps Research Institute Detailed structural imagery of public bnAbs and where they bind to SARS-CoV-2 (green helix) and MERS-CoV (orange helix). These bnAbs recognize the S2 region of the viral spike protein, which is relatively conserved and could lead to the development of a broad coronavirus vaccine and related antibody therapies.
