Leukemia inhibitory factor (LIF) is immunohistochemically localized in tubal ectopic pregnancy.

Leukemia inhibitory factor (LIF) is essential for implantation of the embryo in the endometrium. It is not clear whether the blastocyst requires expression of LIF for implantation into tissues other than endometrium. Immunohistochemical localization of LIF was performed in the fallopian tube of 20 women with ectopic pregnancies, 7 women with normal pregnancies and 20 healthy non-pregnant women.

Protective effect of caffeic acid phenethyl ester (CAPE) on fluoride-induced oxidative stress and apoptosis in rat endometrium.

High fluoride intake may affect biological systems by increasing free radicals, which may enhance lipid peroxidation levels of the tissues, thus leading to oxidative damage. Caffeic acid phenethyl ester (CAPE), a component of honeybee propolis, protects tissues from reactive oxygen species mediated oxidative stress in ischemia-reperfusion and toxic injuries. Several studies suggest that supplementation with anti-oxidant can influence fluoride induced tissue damage.

Serum lipid peroxidation and antioxidant potential levels in hyperemesis gravidarum.

Hyperemesis gravidarum (HEG) is a severe form of nausea and vomiting with unknown etiology. Recent studies have suggested that there might be an etiologic role for HELICOBACTER PYLORI (HP) in HEG. HP is a Gram-negative bacterium that colonizes the gastric mucosa, increases the generation of reactive oxygen species (ROS), and decreases plasma antioxidants such as ascorbic acid.
