A giant built-in electric field in the growth direction makes excitons wide GaN/(Al, Ga)N quantum wells spatially indirect even absence of any external bias. Significant densities can accumulate electrostatic traps imprinted well plane by a thin metal layer deposited on top heterostructure. By jointly measuring resolved photoluminescence and photo-induced current, we demonstrate that exciton de...

Perfusion studies were performed in healthy volunteers to test the hypothesis that net fluid secretion induced by fatty acids is accompanied by parallel reduction in solute transport. Ricinoleic acid provoked a marked net secretion of fluid and concomitantly inhibited the absorption of all solutes tested; these included glucose, xylose, L-leucine, L-lysine, Folic acid, and 2-mono-olein. Oleic a...

Background: We sought to compare the effectiveness and safety of sublingual versus vaginal misoprostol for the termination of pregnancy with a live full-term fetus.Methods: This randomized, triple-blind, placebo-controlled clinical trial was performed on 200 primiparous women with normal, singleton, full-term pregnancies candidated for the induction of labor. Sublingual and vaginal tablets cont...

Perfusion studies of the normal human jejunum were performed to test whether dihydroxy bile acids and hydroxy fatty acids inhibit the absorption of oleic acid, since previous reports documented their inhibitory effects on the absorption of several other organic solutes. 3 mM deoxycholate and 7 mM glycodeoxycholate inhibited the absorption of 3 mM oleic acid in isotonic micellar solutions while ...
