Front Cover: In article 2300090, Seda Kizilel, Erkan Senses, and co-workers entrap liposomes- artificial models of biological cells- in PEG hydrogels mimicking various tissue environments. The liposomes are shown to escape from the hydrogel meshes response large oscillatory shear deformation due repeated stretching releasing network strands without losing their structural integrity.
Structural properties of paeonol-encapsulated liposomes containing cholesterol or stigmasterol at 37°C have been investigated by synchrotron small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS) techniques. We compared the structural properties of pure dipalmitoylphosphatidylcholine (DPPC) liposomes, sterol–DPPC liposomes, and those of paeonol–sterol–DPPC liposomes at diffe...
BACKGROUND Whether sonography is an appropriate imaging modality for cervical lymph nodes in patients with papillary thyroid microcarcinoma (PTMC) remains unclear. Hence, this study aimed to evaluate the diagnostic value of ultrasonography (US) features for lymph node metastasis in PTMC. METHODS Seven hundred twelve patients with PTMC who underwent conventional ultrasonography examinations of...
The authors have examined the fate of intravitreally injected liposomes in the aphakic, vitrectomized eye of the rabbit. Liposomes labelled with 125[I]-p-hydroxybenzimidylphosphatidylethanolamine were eliminated rapidly from the intraocular fluid. Nonetheless, a significant fraction of these liposomes were found to bind to various ocular tissues including the retina, iris, sclera, and cornea. U...
To achieve effective active targeting in a drug delivery system, we previously developed dual-targeting (DT) liposomes decorated with both vascular endothelial growth factor receptor-1 (VEGFR-1)-targeted APRPG and CD13-targeted GNGRG peptide ligands for tumor neovessels, and observed the enhanced suppression of tumor growth in Colon26 NL-17 tumor-bearing mice by the treatment with the DT liposo...
Specific targeting of tumors by combined delivery of drugs and of imaging agents represents an attractive strategy for treatment of cancer. The aim of the present study was to investigate whether neural cell adhesion molecule (NCAM)-targeted liposomes may enhance drug delivery and allow magnetic resonance imaging (MRI) in a severe combined immunodeficient mouse model of NCAM-positive Kaposi's s...
