Uterine Artery Diastolic Notching & Apelin-13 and 36
Investigation of the Relationship Between Uterine Artery Doppler Diastolic Notching and Serum Apelin-13 and Apelin-36 Concentrations Between the 11th and 14th Weeks of Pregnancy
Study Overview
Detailed Description
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.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Uterine artery notch negative group
Pregnant women who did not have diastolic notching in uterine artery Doppler between the 11th and 14th weeks of pregnancy constituted the uterine artery notch negative group.
|
there is no intervention in this study
|
Uterine artery notch positive group
Pregnant women with unilateral or bilateral diastolic notching detected in uterine artery Doppler between the 11th and 14th weeks of pregnancy formed the uterine artery notch positive group.
