Chemotherapy drugs react differently to radiation while in water

Cancer treatment often involves a combination of chemotherapy and radiotherapy. Chemotherapy uses medication to stop cancer cells reproducing, but the medication affects the entire body. Radiotherapy uses radiation to kill ...

On the way to nanotheranostics

Theranostics is an emerging field of medicine whose name is a combination of "therapeutics" and "diagnostics." The idea behind theranostics is to combine drugs and/or techniques to simultaneously—or sequentially—diagnose ...

Researchers selectively eliminate cells that express the oncogene RAS

The RAS oncogene is activated in 30 percent of human cancers, and results in the proliferation and transformation of tumor cells. No effective inhibitor has been found for this protein to date.

Optimizing proton beam therapy with mathematical models

Particle beam therapy is increasingly being used to treat many types of cancer. It consists in subjecting tumours to beams of high-energy charged particles such as protons. Although more targeted than conventional radiotherapy ...

Light and sound gauge the temperature of deep tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient's tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures ...

Radiotherapy: Repairing proteins in search of the ring to protect DNA

To understand why some cancer cells resist radiotherapy, an international team of researchers has used crystallography to "photograph" the first moments of the molecular ballet that allows these cells to repair their DNA. ...
