  • Novel coronavirus' spike protein plays additional key role in illness

    5 days ago - By ScienceDaily

    A new study shows that COVID-19 is a vascular disease, demonstrating exactly how the SARS-CoV-2 virus damages and attacks the vascular system on a cellular level. The findings help explain COVID-19's wide variety of seemingly unconnected complications, and could open the door for new research into more effective therapies.

  • Researchers discover that Kefir can halt cytokine storms observed during SARS-CoV-2 infections

    Researchers discover that Kefir can halt cytokine storms observed during SARS-CoV-2 infections

    5 days ago - By Natural News

    One of the most important areas of scientific research for combating SARS-CoV-2 involves understanding cytokines and mitigating cytokine storm. Cytokines are cell signaling molecules that facilitate immune responses. These molecules communicate between cells to stimulate the movement of immune responsive cells toward sites of inflammation and infection. Israeli scientists have found that yogurt...

  • Low risk of infection in babies born to mothers with COVID-19, study finds

    5 days ago - By ScienceDaily

    Researchers have studied newborn babies whose mothers tested positive for SARS-CoV-2 during pregnancy or childbirth. The results show that although babies born of test-positive mothers are more likely to be born early, extremely few were infected with COVID-19.

  • Severe COVID-19 cases can be predicted by new test

    5 days ago - By ScienceDaily

    Researchers describe a two-step prognostic test that can help predict a patient's response to infection with SARS-CoV-2. The test combines a disease risk factor score with a test for antibodies produced early in the infection. It could be administered at the time of diagnosis to help guide therapeutic choices before the most severe symptoms appear, the researchers said.

  • SARS-CoV-2 antibodies are detectable up to a year after infection, finds study

    5 days ago - By News Medical

    A team of scientists from the United States has recently investigated the robustness and durability of anti-severe acute respiratory syndrome coronavirus 2 antibodies in coronavirus disease 2019 patients. Their findings reveal that COVID-19 patients exhibit a strong anti-SARS-CoV-2 antibody response for up to 1 year and that the robustness of antibody response depends on the patient's age and disease severity.
