Nanotherapy: Controlled delivery of chemotherapeutics to fight cancer stem cells

Chemotherapy is one of the most used treatments against cancer, along with surgery and radiotherapy. In a chemotherapy treatment, one or several drugs are administered to the patient to remove or damage cancer cells. Nevertheless, ...

Fragmenting ions and radiation sensitizers

A new study using mass spectrometry is helping piece together what happens when DNA that has been sensitized by the oncology drug 5-fluorouracil is subjected to the ionising radiation used in radiotherapy.

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 ...
