The hydrolysis of O-arylphosphorothioates by protein-tyrosine phosphatases (PTPases) was studied with the aim of providing a mechanistic framework for the reactions of this important class of substrate analogues. O-arylphosphorothioates are hydrolyzed 2 to 3 orders of magnitude slower than O-aryl phosphates by PTPases. This is in contrast to the solution… (More)
Retropharyngeal or parapharyngeal abscesses developing after intubation are rare. This can present as surgical emergency post extubation. We report a case of retropharyngeal abscess that probably occurred as a complication of laryngeal mask insertion.
