Maternal overnutrition and obesity during pregnancy can have long-term effects on offspring physiology and behaviour. These developmental programming effects may be mediated by fetal exposure to glucocorticoids, which is regulated in part by placental 11β-hydroxysteroid dehydrogenase (11β-HSD) type 1 and 2. We tested whether a maternal high-fat, high-sucrose diet would alter expression of place...

In a study of 960 pregnancies a significantly higher male to female birth ratio was found among primigravidae who developed HL-A antibodies, which was highest where these were monospecific. In the whole group male births predominated in women with antibodies to HL-A 1 and 11 (first locus) and HL-A 5, 12, and 13 and TYT (second locus).

conclusions overall, incidence of birth trauma in kashan city was lower in comparison with most studies. considering existing risk factors, further monitoring on labor, and delivery management in teaching hospitals are recommended to prevent birth injuries. in addition, careful supervision on students and residents' training should be applied in teaching hospitals. patients and methods in this ...

Non-invasive fetal sex determination is required for biomedical studies, in which some sexual difference would be expected in fetal events, in order to make a choice of male or female fetus. To detect male fetal DNA of the sex-determining region Y gene (SRY) in maternal macaque plasma, nested real-time PCR using the SYBR Green system was developed. In all cases of pregnant macaques with male fe...

OBJECTIVE To test whether Schild's sex-specific formula for estimating fetal weight is more accurate than commonly used regression formulae. METHODS The gender-specific formula and 10 widely used equations were evaluated in a group of 989 pregnancies. Each fetus underwent ultrasound examination with complete biometric parameters within 7 days before delivery. RESULTS Over the whole weight r...

Abstract Background The current study was carried out to investigate the effects of exogenous progesterone on fetal development in rats. Results Placental weights did not vary control and treated groups. Fetal were significantly reduced low- high-dose CVL both treatment groups compared group. In fetuses that received maternal with progesterone, several parts skeleton showed incomplete ossificat...
