Disposition and ultimate fate of a PLA-PEG sustained release polymer after intra-articular injection

preparation and characterization of electrospinning peg-pla nanofibers for sustained release of tamoxifen

Effect of different mass ratio of PLA: PEG segments in PLA-PEG-PLA copolymers on the physicochemical characterization and DNA release profile

Background: Adapting controlled release technologies to the delivery of DNA has the great potential to overcome extracellular barriers that limit gene delivery. This study investigates the effect of different mass ratio of PLA: PEG in the various tri block poly (lactic acid)-poly (ethylene glycol) - Poly (lactic acid) copolymer (PLA-PEG-PLA) on the properties of the resulting nanoparticles. Me...

Self-porating polymersomes of PEG-PLA and PEG-PCL: hydrolysis-triggered controlled release vesicles.

Controlled release polymer vesicles are prepared using hydrolysable diblock copolymers of polyethyleneglycol-poly-l-lactic acid (PEG-PLA) or polyethyleneglycol-polycaprolactone (PEG-PCL). Encapsulation studies with a common anti-cancer agent, doxorubicin, show loading comparable to liposomes. Rates of encapsulant release from the hydrolysable vesicles are accelerated with an increased proportio...

Evaluation of intra-articular injection of bupivacaine in combination with morphine, methylprednisolone, or alone on pain after knee arthroscopy

Background and Aims: Knee arthroscopy is used to diagnose and treat intra-articular lesions. The control of acute pain after arthroscopy requires the use of a method with the least side effects and most efficacies. This study aimed to compare the sedative effect of bupivacaine in combination with morphine, methylprednisolone, or alone in knee arthroscopy after intra-articular injection. Materi...

Arthroscopic capsular release for idiopathic frozen shoulder with intra-articular injection and a controlled manipulation

INTRODUCTION The aim of this prospective study was to assess the immediate and long-term effectiveness of arthroscopic capsular release in a large cohort of patients with a precise and isolated diagnosis of stage II idiopathic frozen shoulder. METHODS All patients underwent a preoperative evaluation. Patients with secondary frozen shoulder and those with concurrent pathology at arthroscopy we...
