Résumé
Objective To assess the value of a fibrin-targeted contrast agent (EP-2104R) for MR detection of thrombus, and to compare this modality with non-contrast-enhanced (NCE) MRI and Gd-DTPA injection at acute period after thrombus generation. Methods Thrombus was induced with external injury and stasis in 5 rabbits. MRI was performed before and after contrast agent injection at 6.0 h after injury, and the MRI findings were compared with that of histopathologically examinations. Results EP-2104R enhanced MRI accurately detected thrombus, which was superior to both NCE and Gd-DTPA injection (P<0.001). Gd-DTPA injection was not associated with improvement of thrombus detection. Conclusion Being a fibrin-targeted MR contrast agent for in vivo detection of acute thrombus, EP-2104R is superior to NCE MRI and Gd-DTPA injection.
Résumé
The recent report "The Consensus Coding Sequences of Human Breast and Colorectal Cancers"published in Science represents the first unbiased systematic mutational analysis of human genome at any disease states after the completion of The Human Genome Project. It was tentatively discussed how to take advantage of the candidate cancer genes found in this study in discovery of novel targets of therapeutic drugs. In addition, the penitential values of the candidate cancer genes in identification of patients at high risk of cancer, and in renewing classification of tumors based on underlying molecular mechanisms are introduced.
