The aggregation of personal attributes into user profiles is a significant privacy concern. Existing attribute management systems support the controlled release of attributes and unlinkability between session protocols, but do not address the problem that attributes distributed in this way may be data-mined for features that allow user profiles to be reconstructed. This paper identifies the agg...

This work introduces the HAP system, a software DSM that dynamically adapts to the parallel application’s sharing patterns. Adaptation is based on a constantly categorization of the sharing experienced by each page. Migratory and producer/consumer pages are managed in a single-writer mode and may be updated, while falsely-shared pages are managed in multiple-writer mode and under invalidated pr...

Objective(s): Nanoparticles (NPs) are known for their specific accumulation in the inflamed tissues of the colon and thus allow a selective delivery to the site of inflammation with minimum adverse effects. The main objective of this work is to attain mesalamine loaded chitosan nanoparticles as a carrier for oral delivery. Methods: In this study, me...

Background: Adapting controlled release technologies to the delivery of DNA has the great potential to overcome extracellular barriers that limit gene delivery. This study investigates the effect of different mass ratio of PLA: PEG in the various tri block poly (lactic acid)-poly (ethylene glycol) - Poly (lactic acid) copolymer (PLA-PEG-PLA) on the properties of the resulting nanoparticles. Me...

Sodium salicylate containing microemulsions have been formulated, based on the previous phase diagram studies, using a pharmaceutically acceptable surfactant and oil. The effects of formulation variables on the release profile of the drug from microemulsion through intact rat skin were also determined experimentally. In this investigation, two commercially available lecithins (namely Epikuron 2...

Ketorolac tromethamine (KT) containing microemulsion-based gels (MBGs) have been formulated, based on the previous phase diagram studies, using a pharmaceutically acceptable surfactant (soybean lecithin; Epikuron 200) and oil (isopropyl myristate; IPM) and the effect of formulation variables on the release profile of the drug from MBGs through intact guinea pig skin and various artificial membr...

The present study was carried out with an objective of preparation and in vitro evaluation of floating tablets of hydroxypropyl methyl cellulose (HPMC) and polyethylene oxide (PEO) using ranitidine hydrochloride as a model drug. The floating tablets were based on effervescent approach using sodium bicarbonate a gas generating agent. The tablets were prepared by dry granulation method. The effec...

Paclitaxel-eluting bioresorbable core/shell fiber structures for stent applications and local cancer treatment were developed and studied. These structures were composed of a polyglyconate core and a porous PDLGA shell loaded with the anti-proliferative agent paclitaxel, prepared using freeze drying of inverted emulsions. The investigation of these new composite fibers focused on the effects of...
