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...

OBJECTIVES The study aims at applying pharmaceutical nanotechnology and D-optimal fractional factorial design to screen and optimize the high-risk variables affecting the performance of a complex drug delivery system consisting of glimepiride-Zein nanoparticles and inclusion of the optimized formula with thermoresponsive triblock copolymers in in situ gel. METHODS Sixteen nanoparticle formula...

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 ...

PURPOSE Drug-eluting stents (DES) based on permanent polymeric coating matrices have been introduced to overcome the in stent restenosis associated with bare metal stents (BMS). A further step was the development of DES with biodegradable polymeric coatings to address the risk of thrombosis associated with first-generation DES. In this study we evaluate the biocompatibility of biodegradable pol...

Traditional bolus vaccines often fail to sustain robust adaptive immune responses, typically requiring multiple booster shots for optimal efficacy. Additionally, these provide few opportunities control the resulting subclasses of antibodies produced, which can mediate effector functions relevant distinct disease settings. Here, it is found that three scaffold-based vaccines, fabricated from pol...

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...

A critical review: the ring-opening polymerization of cyclic esters provides access to an array of biodegradable, bioassimilable and renewable polymeric materials. Building these aliphatic polyester polymers into larger macromolecular frameworks provides further control over polymer characteristics and opens up unique applications. Polymer stars, where multiple arms radiate from a single core m...
