TL;DR: The sustained release capacity of the PLGA/PEG-g-CHN composite membranes, together with their compliant and stable mechanical properties, renders them ideal matrices for atrial fibrillation.
Abstract: Ibuprofen-loaded composite membranes composed of poly(lactide-co-glycolide) (PLGA) and poly(ethylene glycol)-g-chitosan (PEG-g-CHN) were prepared by electrospinning. The electrospun membranes were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), mechanical evaluation and contact angle measurements. Shrinkage behavior of the membrane in buffer at 37°C was also evaluated. It was found that PLGA glass transition temperature (T g) decreased with increasing PEG-g-CHN content in the composite membranes, which results in a decrease in tensile stress at break but an increase in tensile strain of the membranes. The degree of shrinkage of these composite membranes decreased from 76 to only 3% when the PEG-g-CHN content in the membranes increased from 10 to 30%. The presence of PEG-g-CHN significantly moderated the burst release rate of ibuprofen from the electrospun PLGA membranes. Moreover, ibuprofen could be conjugated to the side chains of PEG-g-CHN to prolong its rel...

TL;DR: In this article, the temperature location of the effective glass transition (Tg), which immediately precedes the non-equilibrium melting transition of amylopectin microcrystallites and controls the melting process associated with starch gelatinization, was identified for native granular wheat and waxy corn starches, heated at 10°C min−1 in the presence of water added to 55% (by weight) total moisture to facilitate temporal resolution of the thermal events.
