fibrous dysplasia (fd) is an osseous growth dis-order, producing immature bone and characte-rized by the replacement of normal bone with fibro-osseous connective tissue. it is a bone dys-plasia that has the potential to cause significant cosmetic and functional disturbances, particularly in the craniofacial skeleton. cra-niofacial fibrous dysplasia is one of the three types of polyostotic fibro...

background chromosomal aberrations are one of the most common causes of mental retardation (mr). objectives in this study, in order to identify the rate of chromosomal abnormalities in idiopathic mr, 50 mr patients at a charity center in hamadan, iran, were investigated. methods fifty mentally retarded male patients without specific chromosomal abnormalities (e.g., down syndrome, fragile x synd...

BACKGROUND Pregnancies conceived by assisted reproductive technology (ART) are at increased risk of adverse outcomes. Previous studies have suggested increased placental weight and increased placental weight/birthweight ratio in pregnancies associated with adverse outcomes. We therefore studied the association of ART with placental weight and placental weight/birthweight ratio. METHODS We inc...

the hemopoietic activity of the human placenta was studied in vitrc under various conditions in order to assess the optimal conditions of protein synthesis and colony stimulating factor (csf) production by this tissue. the hemopoietic activity of placental tissue was assayed by the semi -solid agar medium technique. in order to obtain maximum hemopoietic activity, various stimulators were exami...

The placenta is the vital support organ for the developing fetus. This article reviews current ultrasound (US) methods of assessing placental function. The ability of ultrasound to detect placental pathology is discussed. Doppler technology to investigate the fetal, placental, and maternal circulations in both high-risk and uncomplicated pregnancies is discussed and the current literature on th...

Smoking increases the risk of pregnancy complications such as spontaneous abortion and low birth weight (LBW). By cigarette smoke exposure (gestational day, GD3-17), normal-litter-size pregnancy with low birth weight (NP-LBW) and small-litter-size pregnancy with normal birth weight (SP-NBW) in rats were induced. The placental weight in SP-NBW was twice the weight of the normal in contrast with ...

Preeclampsia is a life-threatening disorder characterized by maternal gestational hypertension and proteinuria that results from placental dysfunction. Placental abnormalities include abnormal syncytiotrophoblast and a 50% reduction in placental expression of the transcription factor Gcm1. In mice, homozygous deletion of Gcm1 prevents syncytiotrophoblast differentiation and is embryonic lethal....

The hemopoietic activity of the human placenta was studied in vitrc under various conditions in order to assess the optimal conditions of protein synthesis and colony stimulating factor (CSF) production by this tissue. The hemopoietic activity of placental tissue was assayed by the semi -solid agar medium technique. In order to obtain maximum hemopoietic activity, various stimulators were ...
