The combination of coumarin and cimetidine has yielded objective tumor regressions in patients with metastatic renal cell carcinoma and malignant melanoma. While the mechanism of action of cimetidine appears to be immunomodulatory, coumarin appears to have direct effects on tumor cells as well as immunomodulatory activity. We utilized monoclonal antibody(More)
Clinical acute graft-versus-host disease (aGVHD) was correlated with alterations in PBL phenotype and skin immunohistology in 52 patients transplanted with HLA-identical bone marrow. Concurrent with the emergence of aGVHD, there was a profound decrease in absolute number of CD3- T cells and an increase in CD3-CD16+, CD56+ (a subset of which coexpress CD8+(More)
Hyperpolarized substrates prepared via dissolution dynamic nuclear polarization have been proposed as magnetic resonance imaging (MRI) agents for cancer or cardiac failure diagnosis and therapy monitoring through the detection of metabolic impairments in vivo. The use of potentially toxic persistent radicals to hyperpolarize substrates was hitherto(More)
