A glycoprotein immunologically related to plasma cold-insoluble globulin (CIG) and fetal skin fibroblast fibronectin has been purified from second-trimester human amniotic fluid. This protein (amniotic fluid fibronectin) migrated more slowly than CIG on sodium dodecyl sulfate gel electrophoresis and showed greater polydispersity which could result, at least in part, from heterogeneity in glycos...

OBJECTIVE To investigate methionine metabolism during normal human embryonic development by measuring levels of methionine and total homocysteine in samples of maternal serum, extra-embryonic coelomic fluid, and amniotic fluid. DESIGN Cross-sectional observational study. SETTING Collaboration between St Bartholomew's Hospital, London, and the University Hospital of Nijmegen in The Netherlan...

Genital mycoplasmosis is important as an animal model for the interaction between infectious agents and the host during pregnancy as well as in its own right as a confounding variable affecting research projects in which the rat is used as a model to study reproductive function and physiology. We report the in utero transmission of Mycoplasma pulmonis and the development of placentitis, amnioni...

OBJECTIVE Prenatal androgen exposure has been suggested to play a role in polycystic ovary syndrome. Given the limited information on what maternal characteristics influence maternal testosterone levels, and the even less explored routes by which female fetus androgen exposure would occur, the aim of this study was to investigate the impact of maternal age, BMI, weight gain, depressed mood and ...

OBJECTIVE The high risk of nonunion represents a challenge in vertebral surgery, thus stimulating new strategies to improve fusion rates. We investigated the effect of 2 different bone grafts and amniotic fluid application on radiologically and histologically evaluated vertebral fusion in an experimental rat model. MATERIALS AND METHODS Forty-eight 24-week-old Sprague Dawley rats were include...

Injection of amniotic fluid stem cells ameliorates the acute phase of acute tubular necrosis in animals by promoting proliferation of injured tubular cells and decreasing apoptosis, but whether these stem cells could be of benefit in CKD is unknown. Here, we used a mouse model of Alport syndrome, Col4a5(-/-) mice, to determine whether amniotic fluid stem cells could modify the course of progres...

OBJECTIVE To identify the frequency and maternal and neonatal factors associated with meconium-stained amniotic fluid at birth. METHODS Cross-sectional study carried out with 2,441 births at an in-hospital birth center in the city of São Paulo (Southeastern Brazil) in March and April, 2005. The association between meconium-stained amniotic fluid and the independent variables (maternal age, pa...

BACKGROUND The aim of this study was to determine the effect of Ramadan fasting on fetal growth and Doppler in-dices of pregnancy. METHODS Fifty two healthy pregnant women of second or third trimester, 25 in fasting group and 27 in non fasting group were included. Growth parameters including biparietal diameter (BPD), femoral length (FL), abdominal circumference (AC), estimated fetal weight, ...

We reviewed the background information and previous clinical studies that considered the use of allogeneic amniotic tissue and fluid (granulized amniotic membrane and amniotic fluid) in the treatment of chronic diabetic foot wounds. This innovation represents a relatively new approach to wound management by delivering a unique allograft of live human cells in a nonimmunogenic structural tissue ...

BACKGROUND Oligohydramnious is threatening condition to fetal health for which some treatment are available and some are under evaluation. Oligohydramnious, is associated with increased pregnancy complication, congenital anomalies and perinatal mortality. There is an inverse relationship between the amniotic fluid index (AFI) and the adverse perinatal outcome. Oligo hydramnlious is clinical con...
