Adhesive and degradative properties of human placental cytotrophoblast cells in vitro. [PDF]
, 1989 Human fetal development depends on the embryo rapidly gaining access to the maternal circulation. The trophoblast cells that form the fetal portion of the human placenta have solved this problem by transiently exhibiting certain tumor-like properties ...

Sonography, EarlyView.ABSTRACT Introduction The purpose of this study was to examine the accuracy of three‐dimensional (3D) Doppler ultrasound imaging to predict successful medical treatment for missed miscarriages. Methods The 129 women included underwent transvaginal ultrasound 24 h after misoprostol administration for missed miscarriage. Endometrial thickness and uterine

Probability distributions for measures of placental shape and morphology [PDF]
arXiv, 2011 Weight at delivery is a standard cumulative measure of placental growth. But weight is a crude summary of other placental characteristics, such as the size and shape of the chorionic plate and the location of the umbilical cord insertion. Distributions of such measures across a cohort reveal information about the developmental history of the chorionic ...

Ultrasound in Obstetrics &Gynecology, EarlyView.ABSTRACT Objectives The ultrasound diagnosis of placental site trophoblastic tumor (PSTT) is challenging owing to a lack of pathognomonic features. Differential diagnosis from other forms of gestational trophoblastic neoplasia (GTN) is critical owing to major differences in prognosis and treatment.

Mathematical modeling of the GnRH pulse and surge generator [PDF]
SIAM Journal on Applied Dynamical Systems, Vol. 6 (2007), No. 2,
pp 441-456, 2005 We propose a mathematical model allowing for the alternating pulse and surge pattern of GnRH (Gonadotropin Releasing Hormone) secretion. The model is based on the coupling between two systems running on different time scales. The faster system corresponds to the average activity of GnRH neurons, while the slower one corresponds to the average activity ...

Isolated asthenozoospermia: What should we know? A narrative review of literature
UroPrecision, EarlyView.ABSTRACT Male infertility contributes to 20%–70% of infertile couple cases worldwide. One of the key challenges in this area is asthenozoospermia or reduced sperm motility. A particular subset, known as isolated asthenozoospermia (iASZ), in which low motility occurs without abnormalities in sperm count or shape, often goes unnoticed and is not well ...
