In recent years, stem cells have become a hot topic of investigation with studies suggesting revolutionary medical benefits due to their ability to be converted into selected types of newly generated cells. Scientists have now come up with a way to help accelerate bone growth through the use of nanotubes and stem cells. This could lead to quicker and better recovery, for example after orthopedic…
Information in patients' records could benefit biomedical research in terms of understanding diseases and their treatments. The drawback is that those records contain confidential information that could identify patients. If that data has to be removed manually, the task is not only painstaking and therefore expensive, but also not foolproof.
Stroke treatment is a question of time. The faster the cerebral infarct can be diagnosed, the less the brain will be damaged. But unfortunately it is not always easy to get the patient to a brain scanner within the required three-hour window. Real-time 3D ultrasound might bring the solution, according to researchers from the Duke University in Durham, NC.
