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 (...
Nanoparticles hold tremendous potential as an effective drug delivery system. In this review we discussed recent developments in nanotechnology for drug delivery. To overcome the problems of gene and drug delivery, nanotechnology has gained interest in recent years. Nanosystems with different compositions and biological properties have been extensively investigated for drug and gene delivery ap...
A new formulation method was developed for preparing poly(D,L-lactic-co-glycolic acid) (PLGA) nanoparticles loaded with recombinant human granulocyte colony-stimulating factor (rhG-CSF). Lyophilized rhG-CSF powder and PLGA polymer were directly co-dissolved in a single organic phase, and the resulting solution was dispersed into an aqueous solution. PLGA nanoparticles encapsulating rhG-CSF were...
Different scaffolds have been designed for ligament tissue engineering. Knitted scaffolds of poly-L-lactic acid (PLLA) yarns and co-polymeric yarns of PLLA and poly(glycolic acid) (PLGA) were characterized in the current study. The knitted scaffolds were immersed in medium for 20 weeks, before mass loss, molecular weight, pH value change in medium were tested; changes in mechanical properties w...
The aim of the current study was to investigate the antitumor potential of poly (D,L-lactic-co-glycolic acid) microspheres (PLGA MSs) containing polyethylene glycol (PEG)-conjugated (PEGylated) tumor necrosis factor-related apoptosis-inducing ligand (PEG-TRAIL). PEG-TRAIL PLGA MSs were prepared by using a water-in-oil-in-water double-emulsion method, and the apoptotic activities of supernatants...
Poly (lactic-co-glycolic acid) (PLGA) copolymers have been extensively used in cancer research. PLGA can be chemically engineered for conjugation or encapsulation of drugs in a particle formulation. We reported that oseltamivir phosphate (OP) treatment of human pancreatic tumor-bearing mice disrupted the tumor vasculature with daily injections. Here, the controlled release of OP from a biodegra...
Various grafting materials are utilised to facilitate regeneration. There is currently a paradigm shift towards applying poly lactic-co-glycolic acid (PLGA), which regarded as an excellent scaffold for tissue engineering. Concentrated growth factor (CGF) has also been reported promote wound healing. Nevertheless, the role of PLGA microspheres substitute bone graft material with CGF in regenerat...
Background. The injuries associated with the spinal cord, including trauma, tumor, or disease, may lead irreparable damage leading to limited loss of mobility, paralysis, and in extreme cases senses. Methylprednisolone (MP) is often used treat acute cord but suffers high dose toxicity. local administration MP can overcome neurological deficits its high-dose systemic administration. Method. In p...
چکیده زمینه و هدف: پلی لاکتید کو پلی گلیکولید (poly d,l-lactic-co-glycolic acid=plga) به عنوان پلیمری زیست سازگار و زیست تخریب پذیر شناخته شده است. این پلیمر اخیرا در مهندسی بافت بسیار مورد توجه قرار گرفته است. هدف از مطالعه ی حاضر بررسی رفتار بیولوژیک سلول های استرومایی مغز استخوان (=bmscs bone marrow stromal cells) در کشت با نانوالیاف plga پوشش داده شده با ژلاتین و یا پلی ال لایزین می باشد. ر...
