Our current understanding of cellular signalling and disease is based on ensemble measurements over a cellular or molecular population. While these measurements have provided valuable information on the molecular circuitry required for cellular function, there is a lack of detail on the spatio-temporal dynamics of signal initiation and propagation at the single molecule and single cellular level.

While these measurements have provided valuable information on the molecular circuitry required for cellular function, there is a lack of detail on the spatio-temporal dynamics of signal initiation and propagation at the single molecule and single cellular level. Single particle (molecule or cell) approaches offer the advantage of being able to detect individual processes including rare events that would be lost in an ensemble measurement. Moreover single particle approaches provide dynamic-kinetic information that does not rely on synchronising a population of molecules or cells. In this proposal we aim to build on our combined expertise in EGF-EGFR signalling, biophysics, biosensors, quantum dot nanotechnology and single molecule spectroscopy to learn more about how EGFR cellular signalling works and how it is impaired in cancer. This project will provide basic information that could lead to the design of more effective drugs directed agaisnt this therapeutic target.Read moreRead less
Analysis Of Low Radiation Dose Outside Of The Treatment Field Received By Cancer Patients Undergoing Radiotherapy

Summary
Every medical intervention is associated with risk. The present proposal aims to quantify the dose from radiation that is delivered outside the actual target region in radiotherapy of breast cancer patients. This information can help the development of better irradiation techniques as well as inform patients and their carers about possible long term side effects. Finally, the research can be used to finetune radiobiological models by comparing clinical outcomes and accurately calculated doses.

Summary
Combined electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) is used to detect the anatomical areas in the brain that show electrical activity. Several centres worldwide use this technique to localise the seizure focus in patients with epilepsy. However, there is a lack of validation of the currently applied techniques. Current analysis methods have been developed and validated for other fMRI paradigms, such as motor tasks.

Several centres worldwide use this technique to localise the seizure focus in patients with epilepsy. However, there is a lack of validation of the currently applied techniques. Current analysis methods have been developed and validated for other fMRI paradigms, such as motor tasks. It is not known whether the same principles are applicable and optimal for fMRI-EEG data. The proposed project aims at validating and optimising the analysis strategies for fMRI-EEG data.Read moreRead less
