Simvastatin (Sim), a lipid-lowering drug has been studied in chronic neuroinflammation associated with degenerative brain disorders due to its potential protective properties against inflammatory reaction, oxidative damage, neuronal dysfunction, and death. Meanwhile, potential application of Sim in neuroinflammation will require a suitable delivery system that can overcome notable challenges pertaining to poor blood-brain barrier (BBB) permeability and side/off-target effects. Herein, we engineered and characterized nano-sized polymersomes loaded with Sim (Sim-Ps) using PEG-PdLLA (methoxy polyethylene glycol-poly(D,L) lactic acid) diblock co-polymers...

Fibers of poly(L-lactic acid) (PLLA)/polyhydroxybutyrate (PHB) with different concentrations of the drug dipyridamole (DPD) were prepared using solvent-free melt electrospinning to obtain a polymeric drug delivery system. The electrospun fibers were morphologically, structurally, thermally, and dynamically characterized. Crazes that resemble lotus root crevices were interestingly observed in the 7:3 PLLA/PHB fibers with 1% DPD. The crystallinity of PLLA slightly decreased as PHB was incorporated, and the addition of DPD significantly reduced the melting temperature of the composite...
