Professor Bown visits Cheltenham Science Festival
Professor Steve Bown visited the world-famous Cheltenham Science Festival 2010, where he spoke about how lasers can be used for the benefit of sick patients. Lasers aren’t just for threatening 007 or zapping mosquitoes; shining lasers on “the nasty bits of tissue…in just the right place at just the right intensity” can utilise the potential of lasers to provide real solutions to the world.
Image Cytometry predicts cancer in Barrett's
An important step forward has been made in predicting the risk of Barrett's patients developing dysplasia and cancer. Using Image Cytometry, scientists can look at the DNA in biopsied cells to determine the status of the patient's cell structure, and thus their chances of developing pre-cancerous and cancerous conditions. Published in the British Journal of Cancer, the research done at the Laser Centre has helped equip physicians with another tool to improve the quality of diagnosis and care for patients with Barrett's.
The below title provides a link to the abstract.
Dr. Lovat explains ESS to Cancer Research UK
Dr. Laurence Lovat described to Cancer Research UK’s reporter Anna Lacey a new type of tool for diagnosing Barrett’s Oesophagus. Elastic Scattering Spectroscopy is a procedure which is currently being trialled at UCLH, and uses a short pulse of light to determine the health of tissue in the oesophagus.
Elastic Scattering Spectroscopy, or ESS for short, can be performed as part of a normal endoscopy, and can avoid the need to take biopsies from patients, thereby giving them greater quality care and less discomfort. The more comfortable patients are in their endoscopies, the more likely other people who need endoscopies are to book an appointment, and get the treatment they may need.
The instantaneous results that ESS can give means fewer lengthy and anxious waits for patients, shorter hospital stays, and faster courses of therapy.
Dr Martin Austwick has had the following abstracts accepted for presentation at international conferences:

Congratulations to Santosh Somasundaram, who won the prestigious Ronald Raven Prize at the recent BASO (British Association of Surgical Oncology) Meeting at the Royal College of Surgeons of England. Santosh presented a paper on the optical biopsy scanner for diagnosis of breast cancer in the sentinel node. This work has also won the Astra Zeneca Scholars award at the forthcoming San Antonio Breast Cancer Symposium.
Austwick is presenting a poster presentation at the European Biophysics
Conference in London entitled "Optical pharmacokinetics for
photosensitizer chemometrics" (Woodhams J, MacRobert AJ, Mosse A,
Eliot-Laize C, Chalau V, Bigio IJ and Bown SG National Medical Laser
Centre, University College London, London, UK Parker R and Kanuck SJ
Department of Engineering, University of Pittsburgh, PA, USA).
Martin Austwick will be presenting two papers at the European Conferences on Biomedical Optics conference being held in Munich. The titles are " Rapid intraoperative diagnosis of sentinel node metastases in breast cancer using elastic scattering spectroscopy scanning" and " Optical pharmacokinetics measurement of photosensitising drug concentrations for photodynamic therapy".
