Blends of poly (lactic acid)(PLA) and poly (3-hydroxybutyrate)(PHB) plasticized with a lactic
acid oligomer (OLA) added at three different concentrations (15, 20 and 30 wt% by weight),
were prepared by an optimized extrusion process to improve the processability and
mechanical properties of these biopolymers for flexible film manufacturing. Morphological,
chemical, thermal, mechanical, barrier and migration properties were investigated and
formulations with desired performance in eco-friendly films were selected. The efficiency of …

Abstract Background Coronary Aneurysms are a focal dilatation of an artery segment> 1.5-
fold the normal size of adjacent segments. Although some series have suggested a
prevalence of 0.3–12%, data are lacking. In addition, they are not mentioned in practice
guidelines. Our aim was investigate its prevalence, management and long-term outcomes.
Methods and results The coronary artery aneurysm registry (CAAR) involved 32 hospitals
across 9 countries in America and Europe. We reviewed 436,467 consecutive angiograms …
