The contemporaneous association between maternal salivary cortisol and fetal motor activity was examined at 32 and 36 weeks gestation. Higher maternal cortisol was positively associated with the amplitude of fetal motor activity at 32 weeks, r(48) = .39, p < .01, and 36 weeks, r(77) = .27, p < .05, and the amount of time fetuses spent moving at 32 weeks during the 50 min observation period, r(4...

abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...

Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex v...

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal he...

Background: Prenatal intoxication with trimethyletin (TMT) induces widespread neuronal death in the central nervous system by inducing oxidative stress. The aim of this study was to evaluate the antioxidant effect of gallic acid (GA) on the neuronal density of the entorhinal cortex, hippocampal pyramidal cells and oxidative stress parameters in the fetal forebrain following TMT intoxication. ...

Fetal responses to induced maternal relaxation during the 32nd week of pregnancy were recorded in 100 maternal-fetal pairs using a digitized data collection system. The 18-min guided imagery relaxation manipulation generated significant changes in maternal heart rate, skin conductance, respiration period, and respiratory sinus arrhythmia. Significant alterations in fetal neurobehavior were obse...

Background: Most studies have failed to identify significant sex differences in movement (or activity) during fetal development. However, the sample sizes and lengths of time fetuses were monitored in these studies have been limited. Aim and methods: Using the recollections provided by a sample of 6,546 mothers, this study examines variations in fetal activity levels for every month of pregnanc...

Purinton, Scott C., Howard Newman, Maria I. Castro, and Charles E. Wood. Ontogeny of estrogen sulfatase activity in ovine fetal hypothalamus, hippocampus, and brain stem. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1647–R1652, 1999.—Ovine parturition is initiated by increases in fetal hypothalamus-pituitary-adrenal (HPA) axis activity, which in turn increase placental estro...

BACKGROUND Stillbirth after 28 weeks gestation affects between 1.3-8.8 per 1000 births in high-income countries. The majority of stillbirths in this setting occur in women without established risk factors. Identification of risk factors which could be identified and managed in pregnancy is a priority in stillbirth prevention research. This study aimed to evaluate women's experiences of fetal mo...
