Abstract Contrast Induced Nephropathy is the most severe side-effect arising after non-ionic iodinated contrast agents (CAs) intravenous administration. The use of antioxidants (i.e., N-Acetylcysteine; NAC) one attempted prevention approaches. Herein, we describe microfluidic-assisted synthesis polymeric nanoparticles (NPs) as new multifunctional blood pool CA. aim this research to co-encapsula...

The purposes of this research were to synthesize and characterize star-shaped poly lactide-co-glycolide-β-cyclodextrin (PLGA-β-CD) copolymer by reacting L-lactide, glycolide and β-cyclodextrin in the presence of stannous octoate as a catalyst. The structure of PLGA-β-CD copolymer was confirmed with 1H-NMR, 13C-NMR and FT-IR spectra. Albumin as a model peptide drug was encapsulated within nanopa...

Poly(lactic-co-glycolic acid) (PLGA) is a biocompatible, biodegradable polymer approved by the FDA and EMA, which most widely used in field of health. In this study, PLGA was synthesized primarily from lactide glycolide polycondensation ring-opening polymerization. Then, amino acid derivatives were reaction acids presence 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). The polymers PLGA, P...

Cholecalciferol, vitamin D3, plays an important role in bonemetabolism by regulating extracellular levels of calcium. Presented here is a study on the effects of the local delivery of cholecalciferol (D3) using nanoparticulate carriers composed of hydroxyapatite (HAp) and poly(D,L-lactide-co-glycolide) (PLGA). Multifunctional nanoparticulate HAp-based powders were prepared for the purpose of: (...

Olaparib (OLP) is an orally active poly (ADP-ribose) polymerase enzyme inhibitor, approved for treatment the metastatic stage of prostate, pancreatic, breast and ovarian cancer. Due to its low bioavailability, increase in dose frequency required achieve therapeutic benefits, which also results associated toxicity patients. In current study, OLP-loaded (d,l-lactide-co-glycolide) (PLGA) nanoparti...

Docetaxel is a member of taxan family of antineoplastic agents widely used in cancer chemotherapy. However, application of conventional chemotherapy with commercial formulation has been accompanied with matters of concern regarding drug’s biodistribution, pharmacokinetics, and pharmacodynamics. Polymeric nanoparticles have been widely used as unique drug delivery vehicles to circumvent such pro...

Pluripotent adipose tissue-derived stem cells (hASCs) can differentiate into various mesodermal cell types such as osteoblasts, chondroblasts, and myoblasts. We isolated hASCs from subcutaneous adipose tissue during orthopaedic surgery and induced the osteogenic differentiation for 28 days on three different synthetic scaffolds such as polylactide-co-glycolide (PLGA), polylactide-co-glycolide/h...

Nanotechnology is a promising approach both for restoring or enhancing activity of old and conventional antimicrobial agents and for treating intracellular infections by providing intracellular targeting and sustained release of drug inside infected cells. The present paper introduces a formulation study of gentamicin loaded biodegradable nanoparticles (Nps). Solid-oil-in water technique was st...

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...

Poly(DL-lactide-co-glycolide)s (PLGAs) have been proposed as substrata for bone tissue engineering. In the experiments reported herein, we sought to identify the optimum lactide to glycolide ratio, from the series 85:15, 75:25, 50:50, or poly-(DL-lactide) (PLA), for the elaboration of bone matrix by cultured rat bone marrow cells (RBMC) on two-dimensional substrates. Having identified PLGA 75:2...
