By applying the plate count and clear-zone methods, it was confirmed that polylactide (PLA)-degrading microorganisms are sparsely distributed in soil environments. An Amycolatopsis isolate was successfully isolated. Microbial degradation of PLA film was demonstrated; i.e., about 60% of the 100-mg film initially added was degraded by the strain after 14 days of liquid culture.

Polymerization of racemic lactide initiated by divalent ytterbium complexes supported by either dimethylamino-amino bis(phenolate) or methoxy-amino bis(phenolate) ligands proceeds rapidly at room temperature in a living fashion to give heterotactic polylactide with the racemic enchainment of monomer units P(r) ranging from 0.97-0.99.

BACKGROUND Closure of abdominal incisions with different suture materials has been a matter of great controversy. Polypropylene and Polylactide with Polyglycolide are among the commonest suture materials used for closure of abdominal incisions. Objectives of this study were to assess optimal suture material used for closure of elective abdominal incisions and to see complications associated wit...

STUDY DESIGN Experimental study. OBJECTIVE To evaluate and compare the performances of 2 bioresorbable products, Mesofol (a caprolactone/lactide film) and Lactosorb (a polylactide film), as barriers to postoperative peridural adhesions and fibrosis. SUMMARY OF BACKGROUND DATA Postoperative peridural adhesions from scar tissue may be an inciting cause of chronic pain and dysfunction in "fail...
