Effect of three hours of hypoxia on atrial natriuretic factor gene expression in the ovine fetal heart

Article Abstract:

Levels of atrial natriuretic factor (ANF) in fetal plasma may rise in response to lack of oxygen even though ANF gene expression and content in the fetal heart do not change. Researchers used 23 sheep fetuses to evaluate the effect of three hours of oxygen deprivation on ANF gene expression. Plasma levels of ANF rose by six times and remained elevated throughout the three hours. ANF peptide and messenger ribonucleic acid levels were higher in the atria of the heart than in the ventricles in the absence of oxygen, but their content did not change.

Characteristics and treatment of hepatic rupture caused by HELLP syndrome

Article Abstract:

The management of the hepatic rupture caused by hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome is reviewed and maternal and perinatal outcomes of these cases is assessed. Conclusions reveal that a combination of surgical treatment with hepatic artery ligation and omental patching with supportive measures is effective in decreasing the morality rate in hepatic rupture caused by HELLP syndrome.

Evaluation of placental growth factor and soluble Fms-like tyrosine kinase 1 receptor levels in mild and severe preeclampsia

Article Abstract:

Study was conducted to determine if maternal serum concentrations of placenta growth factor (PIGF) and soluble Fms-like lyrosine kinase 1 (s-Flt1) receptor are more abnormal patients with severe preeclampsia compared with mild preeclampsia. PIGF and s-Flt1 serum levels are abnormal in patients with preclampsia compared with controls, but only PIGF is more abnormal in severe preeclampsia with mild preeclampsia.
