Use of roller pump in venovenous extracorporeal membrane oxygenation as an emergency rescue procedure.

A 41 years old male patient, having acute respiratory distress syndrome (ARDS) due to viral pneumonia, was put on venovenous (VV) extracorporeal membrane oxygenation (ECMO). After 3 h of initiation, the ECMO pump malfunctioned. The patient was initially managed on a hand crank for 5 h.

Readily dispersible antimicrobial Ag-SiO Janus particles and their application on cellulosic fabric.

Silver-silica (Ag-SiO) Janus particles with varying functionalities i.e. amine, thiol and epoxy on the exposed surface of SiO particles were synthesized and explored for their antimicrobial activity.
