Serum apelin-13 levels and total oxidant/antioxidant status of patients with Alzheimer's disease.

Objective: We aimed to evaluate apelin-13 levels, total oxidant/antioxidant status in Alzheimer's disease (AD) and to investigate the relationship between these parameters.

Methods: Patients newly diagnosed with AD were enrolled in the study. The control group consisted of age- and gender-matched healthy individuals.

Late pregnancy associated plasma protein A levels decrease in preterm labor.

Objective: The purpose of the present study is to evaluate late, 'at admission', Pregnancy-associated plasma protein-A (PAPP-A) levels as a predictor of preterm birth in women with complaints of preterm labor or preterm painful contractions.

Methods: Prospective cohort study of singleton gestations, 23-37 weeks, and symptoms of preterm labor. Primary end point was delivery < 37 weeks.

PAPP-A levels of late pregnancy in preeclampsia and HELLP syndrome.

Purpose: To determine the relationship between pregnancy-associated plasma protein-A (PAPP-A) levels and preeclampsia and HELLP syndrome at last trimester and to investigate if the severity of preeclampsia would be associated with PAPP-A levels.

Methods: Four groups were constructed; mild-preeclampsia group consisted of 19 women, severe-preeclampsia group 17, HELLP group 5 and control group 32 women. All groups were matched strictly for gestational age at last trimester.
