Magnetic resonance imaging (MRI) has advantages for the assessment of gastrointestinal structures and functions; however, processing MRI data is time consuming and this has limited uptake to a few specialist centers. This study introduces a semiautomatic image processing system for rapid analysis of gastrointestinal MRI. For assessment of simpler regions of interest (ROI) such as the stomach, the system generates virtual images along arbitrary planes that intersect the ROI edges in the original images.

Overexpression of antiapoptotic proteins including Bcl-XL and/or Bcl-2 contributes to tumor initiation, progression, and resistance to therapy by direct interactions with proapoptotic BH3 proteins. Release of BH3 proteins from antiapoptotic proteins kills some cancer cells and sensitizes others to chemotherapy. Binding of Bcl-XL and Bcl-2 to the BH3 proteins Bad, Bid, and the three major isoforms of Bim was measured for fluorescent protein fusions in live cells using fluorescence lifetime imaging microscopy and fluorescence resonance energy transfer.
