A new technique for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI) has been unveiled by UCL scientists. The breakthrough could provide a safer and simpler alternative to standard radioactive techniques and enable radiologists to image tumours in greater detail.

The new technique, called ‘glucose chemical exchange saturation transfer’ (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth. (more…)

Masonic Cancer Center researchers discover a virus-fighting enzyme

It’s well known that sunlight and chemical carcinogens can mutate DNA, and that mutations are essential for cancer to develop. (more…)

Engineered Microvessels Provide a 3-D Test Bed for Human Diseases

Mice and monkeys don’t develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates.

University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.

The findings are published online this week in the Proceedings of the National Academy of Sciences. (more…)
