Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

Advanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Origin of renal cell carcinomas [PDF]

, 2008
[Abstract] Cancer is a heritable disorder of somatic cells: environment and heredity are both important in the carcinogenic process. The primal force is the “two hits” of Knudson’s hypothesis, which has proved true for many tumours, including renal cell ...
