Iron Oxide Mesoporous Magnetic Nanostructures with High Surface Area for Enhanced and Selective Drug Delivery to Metastatic Cancer Cells.

This work reports the fabrication of iron oxide mesoporous magnetic nanostructures (IO-MMNs) via the nano-replication method using acid-prepared mesoporous spheres (APMS) as the rigid silica host and iron (III) nitrate as the iron precursor. The obtained nanosized mesostructures were fully characterized by SEM, TEM, DLS, FTIR, XRD, VSM, and nitrogen physisorption. IO-MMNs exhibited relatively high surface areas and large pore volumes ( = 70-120 m/g and = 0.

CORRELATION OF VISUAL ACUITY WITH FIBROTIC SCAR LOCATION IN TREATED NEOVASCULAR AGE-RELATED MACULAR DEGENERATION EYES.

Purpose: To determine whether the optical coherence tomography location of a subfoveal fibrovascular scar is correlated with visual outcome in eyes successfully treated with antivascular endothelial growth factor agents for neovascular age-related macular degeneration.

Methods: Fifty-six eyes from 56 patients with a subfoveal disciform scar after antivascular endothelial growth factor treatment were included. The initial and final visual acuity, fluorescein angiography, and spectral domain optical coherence tomography scar characteristics were retrospectively reviewed.
