Sphingomyelinase-induced domain shape relaxation driven by out-of-equilibrium changes of composition (Biophysical Society, 2009)Sphingomyelinase (SMase)-induced ceramide (Cer)-enriched domains in a lipid monolayer are shown to result from an out-of-equilibrium situation. This is induced by a change of composition caused by the enzymatic production ...
-
(2009)Background: Marginal ulcer (MU) is an occasional complication after gastric bypass. We studied the incidence of this complication by a prospective routine endoscopic evaluation. 441 morbidly obese patients were studied ...
