We have cloned a human macrophage receptor that binds to apolipoprotein (apo)B48 of dietary triglyceride (TG)-rich lipoproteins. TG-rich lipoprotein uptake by the apoB48R rapidly converts macrophages and apoB48R-transfected Chinese hamster ovary cells in vitro into lipid-filled foam cells, as seen in atherosclerotic lesions. The apoB48R cDNA (3,744 bp) encodes a protein with no known homologs. ...
PURPOSE MRI has become an attractive tool for tumor motion management. Current MR-compatible phantoms are only capable of reproducing translational motion. This study describes the construction and validation of a more realistic, MRI-compatible lung phantom that is deformable internally as well as externally. We demonstrate a radiotherapy application of this phantom by validating the geometric ...
As a typical buffer energy absorbing structure, thin-walled tube filled with foam aluminum has good mechanical properties and absorption characteristics. Therefore, the axial compression performance of square was experimentally studied by quasi-static loading method. On basis existing experimental research theoretical analysis, strain rate is introduced into dynamic theory, mathematical model a...
