Enhanced anti-biofilm and biocompatibility of Zn and Mg substituted β-tricalcium phosphate/functionalized multiwalled carbon nanotube composites towards A. baumannii and Methicillin-Resistant Staphylococcus aureus, and MG-63 cells.

In this work, Zn and Mg substituted β-tricalcium phosphate/functionalized multiwalled carbon nanotube (f-MWCNT) nanocomposites were prepared by the co-precipitation method. The structural, vibrational, morphological and biological properties of the prepared nanocomposites were studied. The structural study revealed that the increase of Zn concentration shifts the β-tricalcium phosphate planes towards higher angle.

Is bactibilia a predictor of poor outcome of pancreaticoduodenectomy?

Background: Although bile infection has been proposed to increase infective complications following pancreaticoduodenectomy, its association with infective complications and non-infective complications like pancreatic fistula is still controversial.

Methods: Seventy-six patients who had undergone pancreaticoduodenectomy between July 2007 and December 2008 were included in a prospective database and their data analyzed. In all patients intraoperative bile from the bile duct was cultured.
