Is the absorption of retinoic acids from the gastrointestinal tract dependent upon chemical structure?
The isomeric position of the polyene chain and the presence of phospholipid in the micellar vehicle have a significant influence on the membrane transport of the retinoic acids.
Tenting area accurately reflects the degree of FMR at a cut-off value of 3.4 cm(2) and has a strong correlation with functional status, plasma BNP, mortality, and hospitalization rates. Tenting area is also an independent predictor of mortality and hospitalizations in patients with NICMP and FMR.
