Witryna17 wrz 2024 · The proposed BLOSI-based B1 field correction using a 3D FLORET read-out trajectory is clinically feasible for sodium imaging which is shown in the brain, heart, kidney, and thigh muscle, which supports using fast B 1 field mapping in the clinical setting. Sodium MRI allows the non‐invasive quantification of intra‐organ sodium … WitrynaThe exosomes harvested from these 293T cells were loaded with miR-26a via electroporation. Results: The engineered exosomes were shown to bind selectively to HepG2 cells via the scavenger receptor class B type 1–Apo-A1 complex and then internalized by receptor-mediated endocytosis. The release of miR-26a in exosome …
