| Abstract |
The goal of this work was to investigate a new nasal carrier for enhanced drug delivery to brain, we call Phospholipid Magnesome. The system contains soft phospholipid vesicles, composed of phospholipid, water, propylene glycol, magnesium salt, and the mucoadhesive polymer, alginate. The carrier was characterized by various methods: electron microscopy, calorimetry, and dynamic light scattering. The ability of the carrier's vesicles to entrap various molecules was studied by CLSM and ultracentrifugation combined with HPLC quantification. Mucoadhesivity of the carrier was tested in vitro using porcine nasal mucosa. The delivery of rohdamine 6G, insulin, and epidermal growth factor was estimated by two methods, multiphoton microscopy and near infrared (NIR) imaging. Pharmacodynamic effects of nasal treatment with oxytocin and insulin incorporated in Phospholipid Magnesome were evaluated in animal models. Results show that the system is composed of soft multilamellar nanosized vesicles with the ability to entrap both lipophilic and hydrophilic molecules. The mucoadhesivity test results indicate a prolonged contact time of the drug with the nasal membrane as compared to control. Multiphoton microscopy and NIR imaging of brain show effective delivery of the tested molecules to brain following nasal administration in Phospholipid Magnesome relative to controls. Moreover, the results of the pharmacodynamic study measuring the antinociceptive effect of oxytocin administrated nasally to an animal model indicate the efficiency of the Phospholipid Magnesome as compared to three control systems. Further, nasal administration of insulin resulted in a strong and prolonged hypoglycemic effect for the drug incorporated in the new carrier but not for control systems. Based on the results of the histopathological test, the carrier is safe for local administration on the nasal membrane. In conclusion, the results of this study suggest that Phospholipid Magnesome nasal carrier is able to improve drug effects, probably by a combined mechanism, absorption enhancement, and prolongation of mucosal contact. |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. 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 19 July 2022.
All research outputs
#4,622,124
of 22,880,230 outputs
Outputs from Drug Delivery and Translational Research
#105
of 512 outputs
Outputs of similar age
#91,348
of 331,755 outputs
Outputs of similar age from Drug Delivery and Translational Research
#5
of 16 outputs
Altmetric has tracked 22,880,230 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 512 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one has done well, scoring higher than 78% of its peers.
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 331,755 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
