Free SARS-CoV-2 spike protein fragments may trigger platelet activation and clot formation in COVID-19

In a recent study under review in the Nature Portfolio journal and currently available on the Research Square* preprint server, researchers investigated the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (SP) in the thrombi (or blood clots).

High-performing age-stratified machine-learning models for the prediction of the severity of COVID-19 progression

The current study aims to use sophisticated machine learning models that stratify patient data by age group to predict disease progression in almost 7,000 patients studied in community hospital settings.

Study illustrates how a protein complex controls genome organization to maintain lineage fidelity

Understanding the molecular mechanisms that specify and maintain the identities of more than 200 cell types of the human body is arguably one of the most fundamental problems in molecular and cellular biology, with critical implications for the treatment of human diseases. Central to the cell fate decision process are stem cells residing within each tissue of the body.

Tumor cells camouflage as platelets to go undetected in the bloodstream, finds study

The Liquid Biopsy and Cancer Interception research group—part of the Biohealth Research Institute in Granada (ibs.GRANADA), in which researchers from the University of Granada (UGR) participate—has discovered that tumor cells pass themselves off as platelets to go undetected in the bloodstream.

Biologists discover gene deletion behind abnormality in blood cancer cells

The mystery is being unraveled of why the control centers, or nuclei, of certain blood cancer cells have a distinctly odd shape.

New insight about how blood clots are formed during wound healing

Research carried out by RCSI University of Medicine and Health Sciences has revealed new information about how blood clots are formed during wound healing.

Unusual partners are key to making more blood vessels

Insufficient oxygen to an area like the heart or legs, called hypoxia, is a cue to our bodies to make more blood vessels, and scientists have found some unusual partners are key to making that happen.

To be one in a million: ‘Who thinks it’s going to be you?’

Monica Melkonian wanted the Johnson & Johnson covid vaccine. It was only one shot and then she would be protected against the virus. So she was thrilled when the vaccination clinic at the Deschutes County Fair & Expo Center on April 7 had her first choice.

Studying coagulopathy in COVID-19

A new study published in the journal Diagnostics provided an overview of ROTEM with a particular focus on interpreting the symmetrical clot formation curve. Researchers also introduced new parameters that could aid in distinguishing between COVID-19 patients and outcomes.

Gene therapy leads to durable transfusion independence in youngest patients with thalassemia

Over 90 percent of patients with transfusion-dependent thalassemia, an inherited blood disorder, no longer needed monthly blood transfusions years after receiving gene therapy, according to an international Phase 3 clinical trial that for the first time included children younger than 12 years of age.

Study identifies a link between mortality of newborns on ECMO and red blood cell transfusion volume

Newborns in respiratory failure who require the life-sustaining support of ECMO also require transfusion of red blood cells. But a new study indicates that the higher volume of these oxygen-carrying blood cells the babies receive, the higher their mortality rate.
