Low transfection efficiency in vivo and failure to deliver therapeutic nucleic acids to the target organs limit the use of cationic liposomes (CLs) in gene therapy. Magnetic drug targeting (MDT) was applied in this study to improve the transfection efficiency and overcome the limitations. Magnetic cationic liposomes (MCLs) were prepared by incorporating MAG-T (magnetite) into CLs. The inclusion of relatively high concentration of MAG-T significantly increased the size of liposomes/lipoplexes, reduced the zeta potential, and decreased the cell viability. The transfection efficiency of MCLs in gene delivery was evaluated by using plasmid DNA (pDNA) containing a luciferase reporter gene in THLE-3 cells. Results suggested that the transfection efficiency of MCLs/pDNA complexes with a relatively lower content of MAG-T (0.75 mg/ml) was the same as that of CLs/pDNA complexes without a magnetic field but was higher (about 2.6-fold) with magnetic induction. Finally, using MCLs/pDNA complexes and a static magnetic field placed over the liver of rats, luciferase reporter gene expression in the liver increased as compared to MCLs/pDNA complexes and CLs/pDNA complexes in the absence of an external magnetic field.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 May 2017.
All research outputs
#12,066,317
of 33,945,077 outputs
Outputs from International Journal of Pharmaceutics
#4,717
of 11,040 outputs
Outputs of similar age
#56,649
of 137,865 outputs
Outputs of similar age from International Journal of Pharmaceutics
#50
of 74 outputs
Altmetric has tracked 33,945,077 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 11,040 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 137,865 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 74 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
