Is an electronic radial scanning echoendoscope superior to a mechanical radial scanning echoendoscope in ultrasound image quality for gastrointestinal tract and pancreaticobiliary lesions?
The ER-ES is certainly superior to the MR-ES in the quality of EUS images of gastrointestinal tract and pancreaticobiliary lesions.
High thioredoxin expression in prechemotherapy tumor samples, but not the increase in thioredoxin expression induced by docetaxel, is associated with resistance to docetaxel in breast cancer. Thioredoxin and ER might be clinically useful in the prediction of a response to docetaxel.
