Nanoscaled devices have great potential for drug delivery applications due to their small size. In the present study, we report for the first time the preparation and evaluation of antitumor efficacy of 5-fluorouracil (5-FU)-entrapped poly (D, L-lactic-co-glycolic acid) (PLGA) nanoparticles with dependence on the lactide/glycolide combination of PLGA. 5-FU-loaded PLGA nanoparticles with two dif...

In this study, the folate decorated biodegradable poly (lactide-co-glycolide) (PLGA) nanoparticles were developed for tumor targeting of anticancer agents. Due to the overexpression of the folate receptor on tumor surface, the folate has been efficiently employed as a targeting moiety for various anticancer agents to avoid their non-specific attacks on normal tissues and also to increase their ...

docetaxel (dtx) is one of the most widely used drugs in oncology due to its high efficacy against several cancers. though, its routine clinical administration, formulated in tween 80, causes serious side effects. polylactide-co-glycolide (plga), biodegradable polyester synthesized and approved for human use, is employed to overcome this problem. in this investigation, we compare the cytotoxic m...

In this study, we proved that the stabilisation of Pickering emulsions by polymer nanoparticles (NPs) heavily depends on characteristics. We prepared NPs with four poly(lactide–co–glycolide) polymers (PLGA), different molar masses (14,000 and 32,000 g/mol) end groups (acid or alkylester). were either bare (without stabilising polymer) covered polyvinyl alcohol (PVA). mixing NP aqueous suspensio...

BACKGROUND Particulate carriers are necessary to control the release of endostar and prolong its circulation in vivo. The purpose of this study was to identify a suitable carrier for the capsulation and delivery of endostar. METHODS We prepared a series of poly (DL-lactide-co-glycolide) (PLGA) and poly (ethylene glycol) (PEG)-modified PLGA (PEG-PLGA) particulate carriers, and then characteriz...

The poly(lactic-co-glycolic acid), known as PLGA, is one of the main bioreabsorbable polymers used in the field of medicine today. This copolymer is widely applied in sutures, devices geared toward the controlled release of medication, and the guided regeneration of bone tissue as it presents a short degradation time. This work aimed to synthesize the 82/18 PLGA (expressed by the mass ratio of ...

The purpose of this study was to prepare poly (D-L) lactide-co-glycolide (PLGA) and ?-caprolactone (PCL) nanofibers containing metronidazole amoxicillin using an electrospinning process as intrapocket sustained-release drug delivery systems for the treatment periodontal diseases. Scanning electron microscopy showed that PLGA PCL produced from uniform bead-free in morphology. obtained had a stro...

Microspheres formulated from poly (D,L-lactic-co-glycolide) (PLGA), a biodegradable polymer, have been extensively evaluated as a drug delivery system. In this study, the preparation, characterization and drug release properties of the PLGA microspheres were evaluated. Simvastatin (SIM)-loaded PLGA microspheres were prepared by oil-in-water emulsion/solvent evaporation method. The microspheres ...

BACKGROUND Peptide based vaccines may suffer from limited stability and inefficient delivery to professional antigen-presenting cells (APCs), such as dendritic cells (DCs). In order to overcome such limitations, several types of biodegradable nanoparticles (NPs) have been developed as carrier system for antigens. The present study describes for the first time the extensive biological characteri...

We recently demonstrated by in vitro experiments that PLGA (poly D, L-lactide-co-glycolide) potentiates T helper 1 (Th1) immune responses induced by a peptide derived from the recombinant major outer membrane protein (rMOMP) of Chlamydia trachomatis, and may be a promising vaccine delivery system. Herein we evaluated the immune-potentiating potential of PLGA by encapsulating the full-length rMO...
