The demonstration by Hamilton et al. (1948) and Werko et al. (1949) that the analysis of timeconcentration curves of intravenously injected Evans Blue (T-1824) gave estimates of the cardiac output in man that corresponded closely with those obtained by the direct Fick method stimulated a widespread use of the dye method. However, those properties of Evans Blue that led Dawson et al. (1920) to s...
Drug efficacy does not always increase sigmoidally with concentration, which has puzzled the community for decades. Unlike standard sigmoidal curves, bell-shaped concentration-response curves suggest more complex biological effects, such as multiple-binding sites or multiple targets. Here, we investigate a physical property-based mechanism for bell-shaped curves. Beginning with the observation ...
BACKGROUND Interventional magnetic resonance imaging (iMRI) has the potential for guiding interventional cardiac procedures in real time. OBJECTIVES To test the feasibility of iMRI guided gene and cell transfer to the heart and to monitor myocardial remodelling after myocardial infarction in a rat model. METHODS The MRI contrast agent GdDTPA, together with either Evans blue dye, or a recomb...
The ability to accurately and easily locate sentinel lymph nodes (LNs) with noninvasive imaging methods would assist in tumor staging and patient management. For this purpose, we developed a lymphatic imaging agent by mixing fluorine-18 aluminum fluoride-labeled NOTA (1,4,7-triazacyclononane-N,N',N''-triacetic acid)-conjugated truncated Evans blue ((18)F-AlF-NEB) and Evans blue (EB) dye. After ...
