OBJECTIVE AMI-227 is an ultrasmall superparamagnetic iron oxide colloid known to enhance tissue T1 and T2 relaxation rates. Animal studies show that AMI-227 has an estimated blood half-life of more than 200 min. In this study, we evaluated the clinical utility of AMI-227 as an MR contrast agent for detection and characterization of focal hepatic lesions, with MR imaging done while the contrast ...

Few studies provide insight into how California principals perceive Proposition 227 and its impact on bilingual education. The findings of a survey distributed to 100 randomly selected California principals with bilingual programs, indicate the law passed by California voters has not changed the perceptions of California principals towards bilingual education. It is now eight years since Propos...

Cross sections for the formation of (225,227)Ac, (223,225)Ra, and (227)Th via the proton bombardment of natural thorium targets were measured at a nominal proton energy of 800 MeV. No earlier experimental cross section data for the production of (223,225)Ra, (227)Ac and (227)Th by this method were found in the literature. A comparison of theoretical predictions with the experimental data shows ...
