Abstract
Iron nanoparticles (MNPs) are known to induce membrane damage and apoptosis of cancer cells. In our study we determined whether FDG coupled with iron oxide magnetic nanoparticles can exert the same destructive effect on cancer cells. This research study presents data involving NIC-H727 human lung, bronchus epithelial cells exposed to conjugated fluorodeoxyglucose conjugated with iron-oxide magnetic nanoparticles and indocyanine green (ICG) dye (FDG-MNP-ICG), with and without the application of a magnetic field. Cell viability inferred from MTT assay revealed that FDG-MNPs had no significant toxicity towards noncancerous NIC-H727 human lung, bronchus epithelial cells. However, percentage cell death was much higher using a magnetic field, for the concentration of FDG-MNP-ICC used in our experiments. Magnetic field was able to destroy cells containing MNPs, while MNPs alone had significantly lower effects. Additionally, MNPs alone in these low concentrations had less adverse effects on healthy (non-target) cells.

Abstract
In this study, we present the design considerations of a device to assist in the
potential treatment of hemorrhagic stroke with the aim of stopping blood from
flowing out into brain tissue. We present and model three designs for the
clinical scenarios when saccular aneurysms rupture in the middle cerebral artery
in the brain. We evaluate and model these three designs using computer aided
design software, SolidWorks, which allows the devices to be tested using finite
element analysis and also enables us to justify that the materials chosen were
suitable for potential use. Computational fluid dynamics modelling were used to
demonstrate and analyse the flow of blood through the artery under conditions of
normal and ruptured states. We conclude that our device could potentially be
useful in the treatment of hemorrhagic stroke, and the modelling process is
useful in assisting in determining the performance of our devices.
