Unusual course of an abdominal aortic aneurysm in a patient treated with chemotherapy for gastric cancer.

Most aortic aneurysms have a degenerative genesis and show a slow expansion over years. Only a few patients with a rapid progression of mycotic or inflammatory aneurysm during some weeks or months have been reported. We report a patient with a rapidly growing symptomatic infrarenal aneurysm with a maximal diameter of 53 mm, which developed over a 5-month period from a normal aorta and did not feature typical signs of degenerative, inflammatory, or mycotic aneurysm.

Near-infrared fluorescence imaging of HER-2 protein over-expression in tumour cells.

The aim of this study was to evaluate in vitro and in vivo imaging of HER-2-over-expressing tumours using near-infrared optical imaging. A fluorochrome probe was designed by coupling Cy5.5 to anti-HER-2 antibodies.
