Current treatment methods for melanoma have some limitations such as less target-specific action, severe side effects and resistance to drugs. Significant progress has been made in exploring novel drug delivery systems based on suitable biochemical mechanisms using nanoparticles ranging from 10 to 400 nm for drug delivery and imaging, utilizing their enhanced penetration and retention propertie...
Magnetic poly (D,L-lactide-co-glycolide) (PLGA)/lipid nanoparticles (MPLs) were fabricated from PLGA, L-α-phosphatidylethanolamine (DOPE), 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-amino (polyethylene glycol) (DSPE-PEG-NH2), and magnetic nanoparticles (NPs), and then conjugated to trans-activating transcriptor (TAT) peptide. The TAT-MPLs were designed to target the brain by magnetic gui...
Although bioactive polymers such as cationic polymers have demonstrated potential as drug carriers and nonviral gene delivery vectors, high toxicity and uncontrolled, instantaneous cellular interactions of those vectors have hindered the successful implementation In Vivo. Fine control over the cellular interactions of a potential drug/gene delivery vector would be thus desirable. Herein, we hav...
Objective: In dental treatments, use of carriers for targeted antibiotic delivery would be optimal to efficiently decrease microbial count. In this study, gentamicin was loaded into polylactic co-glycolic acid (PLGA) microspheres and its release pattern was evaluated for 20 days. Methods: In this experimental study, PLGA microspheres loaded with gentamycin were produced by the W/O/W method....
Drug-eluting stents (DES) are commonly used in coronary angioplasty procedures. A DES elutes drug compounds from a thin polymeric coating into the surrounding coronary artery tissue to reduce in-stent restenosis (a significant lumen loss due to growth of vascular tissue). Biodurable (non-erodible) polymers are often used in the current DES coatings, which stay permanently in the patients. While...
Efficient delivery of antigens through oral immunization is a first and critical step for successful induction of mucosal immunity, which can provide protection against pathogens invading the mucosa. Membranous/microfold cells (M cells) within the mucosa can transcytose internalized antigen without degradation and thus play an important role in initiating antigen-specific mucosal immune respons...
One of the challenges nanotechnology is to improve efficacy treatments for diseases, in order reduce morbidity and mortality rates. Following this line study, we made a nanoparticle formulation with small size, uniform surfaces, satisfactory encapsulation coefficient as target colorectal cancer cells. The results binding uptake prove that using system folic acid works: Using system, cytotoxicit...
Poly(lactic-co-glycolic acid) (PLGA) is the most widely used biomaterial for microencapsulation and prolonged delivery of therapeutic drugs, proteins and antigens. PLGA has excellent biodegradability and biocompatibility and is generally recognized as safe by international regulatory agencies including the United States Food and Drug Administration and the European Medicines Agency. The physico...
Open vascular reconstructions frequently fail due to the development of recurrent disease or intimal hyperplasia (IH). This paper reports a novel drug delivery method using a rapamycin-loaded poly(lactide-co-glycolide) (PLGA) nanoparticles (NPs)/pluronic gel system that can be applied periadventitially around the carotid artery immediately following the open surgery. In vitro studies revealed t...
The purpose of this study is to prepare cationic nanoparticles (NPs) by coating chitosan (CS) on the surface of PLGA NPs and evaluated laser thrombolysis capabilities and photomechanical drug delivery in a blood clot. The tPA encapsulated PLGA and PLGA/ CS nanoparticles were fabricated via the W/O/W double emulsion solvent evaporation surface coating method. The characteristics of NPs are deter...
