About this study

Apelin-13 and apelin-36, which provide vasodilatation through a nitric oxide-dependent mechanism, also play a role in trophoblasts' survival, proliferation, and migration.

Based on this, we aimed to investigate serum apelin-13 and apelin-36 concentrations in pregnant women with and without diastolic notch on uterine artery Doppler between the 11th and 14th weeks of pregnancy.

We hypothesized that apelin-13 and apelin-36 might be associated with the formation of diastolic notch in uterine artery Doppler and serum apelin-13 and apelin-36 concentrations would be lower in the group with a notch in the uterine artery Doppler than in the group without a notch.
