Abstract

Studies of two types of small liposomes, differing with respect to their lipid composition in terms of bilayer fluidity, charge, and hydrophilicity of the liposomal surface, were done to evaluate their usefulness for delivery of encapsulated therapeutic agents to sites of infection. The liposomes showed substantial localization in infected lung tissue after intravenous administration. This was demonstrated in a model of unilateral Klebsiella pneumoniae pneumonia in rats, in which the left lung was infected but the right lung of the same animal developed no infection. The degree of localization in the infected left lung was different for the two types of liposomes. For the liposome type with the longer blood residence time, containing a surface coating of polyethylene glycol, localization in the infected left lung was dependent on the liposomal dose, correlated with the intensity of infection, and reached 9% of the injected liposomal dose in severely infected rats.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
