Removing large brain artery clot, chased with clot-buster shot may improve stroke outcomes
2025-02-07
Research Highlights:
Stroke survivors were more likely to have little or no disability after 90 days if a clot was removed from a large brain artery followed by the injection of the clot-dissolving medication tenecteplase directly into the artery near the blockage, compared to people receiving standard medical treatment after clot removal. In this trial, standard care was clot removal without clot-dissolving medication.
The added treatment may work by dissolving blood clots in the small vessels (microcirculation) near the major blockage, reducing the amount of brain tissue deprived of blood.
The ANGEL-TNK trial found that this approach was ...

And then through the brain nerve center on the tactile signal “calculation” ...
Mitochondria may hold the key to curing diabetes
2025-02-07
Mitochondria are essential for generating energy that fuels cells and helps them function.
Mitochondrial defects, however, are associated with the development of diseases such as type 2 diabetes. Patients who suffer from this disorder are unable to produce enough insulin or use the insulin produced by their pancreas to keep their blood sugar at normal levels.
Several studies have shown that insulin-producing pancreatic β-cells of patients with diabetes have abnormal mitochondria and are unable to generate energy. Yet, these studies were unable to explain why the cells behaved this way.
In a study published in Science, ...
