Recently, polymeric nanoparticles (NPs) have attracted enormous attention as targeted drug delivery vehicles.[1-4] Especially, biodegradable and biocompatible polymeric NPs comprised of poly(lactide-co-glycolide)-b-polyethyleneglycol (PLGA-PEG) block copolymers exhibit optimal physicochemical characteristics such as the ability to incorporate various targeting agents, enhanced immune evasion, c...
Propionibacterium acnes acts a critical role in the development of inflammatory acne when it overgrows in pilosebaceous units. The spread of multiple drug resistance bacteria indicates a growing need for new antimicrobial agents. The objective of this study is to develop lipid vehicles to deliver curcumin and inhibit P. acnes in the skin. The inhibitory activities of the curcumin containing veh...
BACKGROUND Releasing drug molecules at the targeted location could increase the clinical outcome of a large number of anti-tumor treatments which require low systemic damage and low side effects. Nano-carriers of drugs show great potential for such task due to their capability of accumulating and releasing their payload specifically, at the tumor site. RESULTS FLT3 inhibitor - gold nanopartic...
Context: The use of nanotechnology in medicine and more specifically drug delivery is set to spread rapidly. Currently many substances are under investigation for drug delivery and more specifically for cancer therapy. Evidence Acquisition: Nanodiamonds (NDs) have contributed significantly in the development of highly efficient and successful drug delivery systems, and in stem cell therapy. Dru...
The widespread deployment and testing of autonomous vehicles in real-world environments raises key questions about how such systems should be regulated. Much of the current debate presupposes that the regulatory system we currently use for regular vehicles is also appropriate for semiand fully-autonomous ones. In opposition, we first argue that there are serious challenges to regulating autonom...
Transdermal delivery that avoids the presystemic disposition can provide an alternative to oral administration of tadalafil. Accordingly, the aim of this study was to select the best vehicle as the first step in optimization of tadalafil transdermal delivery. The vehicles were used neat or in selected binary combinations and were evaluated for drug solubilization and transdermal delivery. The d...
Conventional emulsions are heterogeneous system in which one immiscible liquid is dispersed as droplets in another liquid. That may be water-in-oil or oil-in-water emulsions. However emulsion can be formulated waterless or without an aqueous phase to produce anhydrous or non-aqueous or oil-in-oil emulsions may be used as reservoirs to deliver lipophilic or hydrolytically unstable drugs, could b...

BACKGROUND Polymeric micelles using amphiphilic macromolecules are promising vehicles for antitumor targeting. In this study, we prepared anticancer agent-incorporated polymeric micelles using novel block copolymer. METHODS We synthesized a block copolymer composed of dextran and poly (DL-lactide-co-glycolide) (DexbLG) for antitumor drug delivery. Doxorubicin was selected as the anticancer dr...
