It is demonstrated that, on a silver oxide surface, direct formation of ethylene oxide (EO) through the reaction between gas phase ethylene and surface oxygen is possible. The direct reaction channel produces EO selectively without competing with acetaldehyde (AA) formation. The oxometallacycle (OMC) forms on an oxygen vacant surface and reduces EO selectivity. Cl adsorption removes these surface vacant sites and hence prevents the formation of the OMC intermediate.
RESUMEN
Variceal bleeding is one of the most important and life-threatening complications of portal hypertension. Although less common than oesophageal varices that have a lower frequency of bleeding, gastric varices tend to result in more severe and mortal bleeding. The Ankaferd Blood Stopper (ABS) has been used with varying success in recent years for the management of bleeding from skin lesions or after dental surgery, and in other clinical conditions in which conventional haemostatic measures have proved to be deficient. In serious bleeding gastric fundal varices, ABS can also act as a bridge in the absence or unavailability of definitive therapies.
