SYNTHESIS AND THERMAL PROPERTIES OF NOVEL BIODEGRADABLE ABCBA PENTABLOCK COPOLYMERS FROM POLY (ETHYLENE GLYCOL), L-LACTIDE AND P-DIOXANONE

Synthesis and Thermal Properties of Novel Biodegradable ABCBA Pentablock Copolymers from Poly (Ethylene glycol), L-Lactide and p-Dioxanone

In this work, new biodegradable ABCBA type pentablock copolymers with different mole ratio of L-lactide and PPDO-b-PEG-b-PPDO triblock copolymer were synthesized and characterized.In the first step, PPDO-b-PEG-b-PPDO triblock copolymer was synthesized via a ring-opening polymerization of P-DiOxanone (PDO) monomer with Poly (Ethylene Glycol) h22a4 t

Partial anomalous pulmonary venous connection with intact atrial septum in a child with ventricular septal defect: a case report

Partial anomalous pulmonary vein connection (PAPVC) is a rare congenital abnormal cardiac defect involving the pulmonary veins draining into the right atrium (RA) directly or indirectly by venous connection.Ninety percent of PAPVCs are accompanied by atrial septal defect (ASD).To our knowledge, there is no previous report of PAPVC with ventricular
