The aim of the present study was to assess leptin/adiponectin ratio in preeclamptic patients compared with normal pregnant women. A cross-sectional study was designed. The study population consisted of 30 preeclamptic patients and 30 healthy pregnant women. Serum levels of total leptin and adiponectin were assessed using commercially available enzyme-linked immunosorbent assay methods. The one-...

Vitamin D insufficiency/deficiency during pregnancy has been linked to increased risk of preeclampsia. Placenta dysfunction plays an important role in the pathogenesis of this pregnancy disorder. In this study, we tested the hypothesis that disturbed vitamin D metabolism takes place in preeclamptic placentas. Protein expressions of vitamin D binding protein (VDBP), 25-hydroxylase (CYP2R1), 1α-h...

AIM Preeclampsia is characterized by a disruption of general vascular dilatation, which is mainly mediated by nitric oxide (NO) and disturbed by reactive oxygen species (ROS). The present study investigated the roles of NO and ROS in the pathogenesis of preeclampsia. METHODS Serum samples were obtained prospectively. Serum levels of NO(2)/NO(3) (NOx) and creatol (CTL), the oxidized metabolite...

Plasma membrane Ca2+-ATPase activity diminishes by about 50% in red blood cells during preeclampsia. We investigated whether the number of Ca2+-ATPase molecules is modified in red cell membranes from preeclamptic pregnant women by measuring the specific phosphorylated intermediate of this enzyme. Also, we isolated the Ca2+-ATPase protein from both normotensive and preeclamptic pregnant women an...

OBJECTIVE To compare serum 25-hydroxy vitamin D level between preeclamptic and normotensive pregnancies. STUDY DESIGN Cross-sectional analytical study. PLACE AND DURATION OF STUDY Department of Physiology, Federal Postgraduate Medical Institute, Shaikh Zayed Hospital, Lahore, in collaboration with Sir Ganga Ram Hospital and Lady Willingdon Hospital, Lahore, from March 2012 to April 2012. ...

CONTEXT Management of preeclampsia often culminates in induced delivery of a very preterm infant. While early termination protects the fetus from an intrauterine death, the newborn then faces increased risks associated with preterm delivery. This practice has increased in recent decades, but its net effect on fetal and infant survival has not been assessed. OBJECTIVE To assess the effect on f...

Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler. Doxycycline inhibits matrix metalloproteinase activity. We tested the hypothesis that matrix metalloproteinase inhibition reduces trophoblast invasion with subsequent ...

In vitro literature studies have suggested that atherosclerotic oxidized low density lipoprotein (OxLDL) inhibits trophoblast invasion. The objective of this study was to determine the levels of OxLDL and to examine the relationship between antioxidative estradiol, estriol, and prooxidative progestin in normal and preeclamptic placental tissues and measure the serum activity of antioxidative pa...
