PURPOSE The objective of this work was to evaluate the effect in the immune response produced by CpG oligodeoxynucleotides (ODN) co-encapsulated with the antigen ovalbumin (OVA) within poly(lactic-co-glycolic) acid (PLGA) 502 and 752 microparticles (MP). METHODS MP were prepared by blending 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) with PLGA and Total Recirculation One Machine System (...
Background and Objective: In the present study, PEGylated liposomal formulation containing doxorubicin was synthesized in order to study the effects of surface charge on its cytotoxicity. Materials and Methods: Liposomal doxorubicin containing DPPC, cholesterol and phospholipid DSPE-mPEG with various amounts of cationic phospholipid, DOTAP, (0, 5.2 and 20%) was prepared by pH gradient ...
BACKGROUND Serum and high ionic strength solutions constitute important barriers to cationic lipid-mediated intravenous gene transfer. Preparation or incubation of lipoplexes in these media results in alteration of their biophysical properties, generally leading to a decrease in transfection efficiency. Accurate quantification of these changes is of paramount importance for the success of lipop...
Background: The general tendency of society in the use of natural extracts as antimicrobial, antioxidant and preservative compounds has increased in recent years. Objective: The purpose of this study is to improve the functional properties of two native plants (Hyssopus officinalis and Eryngium caeruleum M.Bieb) of the country that was accomplished by comparing the increasing stability of the a...
Doxorubicin is used to treat numerous types of tumors including breast cancer, yet dose-associated toxicities limit its clinical application. Here, we demonstrated a novel strategy by which to deliver doxorubicin to breast cancer cells by conjugating cancer cell-specific single-strand DNA aptamers with doxorubicin-encapsulated DOTAP:DOPE nanoparticles (NPs). We utilizing a whole-cell-SELEX stra...
