Abstract:Paramagnetic pH-responsive liposomes have recently been suggested as a promising approach for monitoring by magnetic resonance imaging (MRI) pH changes in tumours. In the present study, the effects of variations in bilayer composition on the relaxometric properties of diacylphosphatidylethanolamine (PE)/dipalmitoylglycerosuccinate (DPSG) liposomal GdDTPA-BMA were investigated both in buffer and blood. A factorial experimental design was used with the variables PE chain length and mol% DPSG. All the relaxometri…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
