Particles capable of homing and adhering to specific vascular biomarkers have potential as fundamental tools in drug delivery for mediation of a wide variety of pathologies, including inflammation, thrombosis, and pulmonary disorders. The presentation of affinity ligands on the surface of a particle provides a means of targeting the particle to sites of therapeutic interest, but a host of other...
Background The round window membrane (RWM) functions as the primary biological barrier for therapeutic agents in the inner ear via local application. Previous studies on inner ear nano-drug delivery systems mostly focused on their pharmacokinetics and distribution in the inner ear, but seldom on the interaction with the RWM. Clarifying the transport mechanism of nanoparticulate carriers across ...
In recent years, utilization of chitosan /tripolyphosphate nanoparticles has been considered greatly as protein delivery vehicles. Effects of a variety of factors on final characteristics of nanoparticles have been studied by many investigators. Although, the objective of this study was to achieve smaller chitosan nano carriers via changing fabrication parameters such as pH and temperature and ...
In this study, folate-functionalized hybrid polymeric nanoparticles (NPs) were prepared as carriers of low water solubility paclitaxel for tumor targeting, which were composed of monomethoxy-poly(ethylene glycol)-b-poly(lactide)-paclitaxel (MPEG-PLA-paclitaxel) and d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS)-folate (TPGS-FOL). NPs with various weight ratios of MPEG-PLA-paclitaxel a...
BACKGROUND Cancerous state is a highly stimulated environment of metabolically active cells. The cells under these conditions over express selective receptors for assimilation of factors essential for growth and transformation. Such receptors would serve as potential targets for the specific ligand mediated transport of pharmaceutically active molecules. The present study demonstrates the speci...
Transdermal drug delivery (TDD) is a non-invasive, topical administration method for therapeutic agents. Transdermal delivery also has advantages including providing release for long periods of time, improving patient compliance, and generally being inexpensive. Despite these advantages, the use of TDD has been limited by innate barrier functions of the skin. Only small (<500 Da), lipophilic mo...
