Mutation stands in the way of healthy blood cell maturation

In the veins, stem cells constantly mature and develop into different blood cells that are necessary for the body to work properly. Now researchers from the University of Copenhagen and EMBL in Heidelberg have discovered exactly how a specific mutation in the stem cells in the blood can obstruct this maturation process. In a new…

High-dose stereotactic body radiotherapy well-tolerated by patients with centrally located lung tumors

Stereotactic Body Radiotherapy (SBRT), a high-dose, precisely delivered radiotherapy, is considered the standard treatment for patients with medically inoperable, node-negative, non-small cell lung cancer (NSCLC). However, this well-tolerated radiation treatment was not previously tested in centrally located NSCLC due to the fact that patients with centrally located lung tumors demonstrate a higher risk for toxicity…
