The contribution of matrix metalloproteinases (MMP) to timely discharge of the placenta from bovine uterus at parturition is yet inconclusive, partly because of the presence of multiple MMP forms in situ. In the current study, the expression of different gelatinase subtypes on non-retaining placentas of Holstein cows was fingerprinted by using gelatin zymography. Different topographic regions o...

BACKGROUND Placenta previa is characterized by the abnormal placenta overlying the endocervical os, and it is known as one of the most feared adverse maternal and fetal-neonatal complications in obstetrics. OBJECTIVES We aimed to obtain overall and regional estimates of placenta previa prevalence among deliveries in Mainland China. METHODS The research was performed a systematic review, fol...

Placenta is the most important and vital organ of intrauterine life. It is fountainhead of human existence. The placenta is formed from elements of membrane which surround the developing fetus and the uterine endometrium and provide the means for physiological exchange between the fetal and maternal circulation and it shows various histological and histochemical changes in case of diabetic moth...

The author presents a case of in vitro fertilization pregnancy complicated by morbidly adherent placenta in a patient with congenital bilateral ovarian agenesis. A 31-year-old woman with congenital bilateral ovarian agenesis who had undergone two previous dilatation and curettage procedures conceived following in vitro fertilization with a donor egg. Spontaneous labor occurred at 38 weeks and 5...

Abnormal attachment of the placenta (Placenta accreta, increta, and percreta) is an uncommon but potentially lethal cause of maternal mortality from massive postpartum hemorrhage. A 33-yr-old woman, who had been diagnosed with a placenta previa, was referred at 30 weeks gestation. On ultrasound, a complete type of placenta previa and multiple intraplacental lacunae, suggestive of placenta accre...

The incidence of placenta accreta and maternal death are substantially increased due to the increased rate cesarean section [1,2]. The incidence of placenta accreta reported approximately 0.8 to 3 per 1000 deliveries. Maternal mortality related to placenta accreta and its complications occurs approximately as high as 6-7% [3]. Placenta accreta is the most common cause for emergency postpartum h...

Maternal placentophagy has recently emerged as a rare but increasingly popular practice among women in industrialized countries who often ingest the placenta as a processed, encapsulated supplement, seeking its many purported postpartum health benefits. Little scientific research, however, has evaluated these claims, and concentrations of trace micronutrients/elements in encapsulated placenta h...

Objective: To assess the value of adding three-dimensional (3D) power Doppler (as a diagnostic technique) to grayscale in the prenatal diagnosis of placenta accreta. Material and Methods: One hundred pregnant women with persistent placenta previatotalis (after 28 weeks' gestation) were prospectively enrolled into this study. Gray-scale transabdominal ultrasound was performed to detect loss of t...

Background: The placenta is the most important organ for the development of the embryo and fetus because of its transport functions. Over the past several decades, a small number of proteins were tested that can cross the placenta, however, there have been no high throughput and comprehensive studies of protein crossing of the placenta. Methods: To evaluate the in situ perfused placenta model a...
