Objective(s): The placenta provides nutrients and oxygen to embryo and removes waste products from embryo’s blood. As far as we know, the effects of exposure to Wi-Fi (2.4 GHz) signals on placenta have not been evaluated. Hence, we examined the effect of prenatal exposure to Wi-Fi signals on anti-oxidant capacity, expressions of CDKNA1, and GADD45a as well as apoptosis...

Dangerous placenta previa refers to somebody has a history of cesarean section while this pregnancy was placenta previa with the placenta attached to the original scar. The placenta can be adhered to the surface of the uterus, invasion into myometrium or completely penetrate the muscle and tissues in these placenta previa patients. It happens in these persons like older maternal ages (over 35 y...

Placenta is a unique organ, without which the very phenomenon of human pregnancy impossible. Semiallogeneous nature, localization placenta, complex and heterogeneous cellular composition determines its multifaceted role in course physiological pregnancy, indicates importance studying this organ number reproductive pathologies. The purpose review was to analyze literature sources illustrating en...

BACKGROUND Placenta accreta/increta/percreta is associated with major pregnancy complications and is thought to be becoming more common. The aims of this study were to estimate the incidence of placenta accreta/increta/percreta in the UK and to investigate and quantify the associated risk factors. METHODS A national case-control study using the UK Obstetric Surveillance System was undertaken,...

Placenta accreta is defined as an abnormal adherence of the placenta to the uterine wall owing to a faulty or an absent decidua basalis. Placenta accreta is further subdivided into placenta accreta vera, increta and percreta, depending on the level of invasion of the uterine wall and surrounding structures. Placenta percreta represents invasion to the serosa and/or other pelvic structures. We h...

Placenta accreta occurs when the deciduas basal is that separates the placental villi from the myometrium is missing. Classification is divided in 3 grades based on histopathologic analysis consisting on: placenta accreta, increate and percent. Placenta accreta occurs when the chorionic villi of the placenta enters in contact with the myometrium. In placenta increta, the chorionic villi invade ...

background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...

background: the objective of the study was to evaluate the presence of neospora caninum organisms in the brain of aborted fetuses and placentas of full-term calves born of seropositive cows. methods: during 2006-2007, 12 brains of aborted calves from neospora seropositive cattle and 7 pla­centas from seropositive dams giving birth to full-term calves, from four dairy cattle farms located around...

objective herpes simplex virus (hsv) infection during pregnancy may lead to fetal loss. the aim of this study was to explore the infection rate of hsv type 1 and 2 infection associated with spontaneous abortion in a pilot case-control study in two cities of iran in 2010. patients and methods placenta and curettage samples from 35 healthy full term neonates and 35 cases of spontaneous abortion w...

Risk of birth defects in multiple pregnancies Frequency of monozygotic twins remains constant, while dizygotic twins become more frequent as maternal age increases. In these cases the risk that at least one fetus is aneuploid will be twice the maternal age risk for a singleton while the probability of both fetuses being involved is minimal. Dizygotic twins have a six fold increased risk that on...
