Assessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.
OBJECTIVE Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain. The aim of the study was to determine whether in fetuses with spina bifida this displacement of th...

OBJECTIVE To update the likelihood ratio for trisomy 21 in fetuses with absent nasal bone at the 11-14-week scan. METHODS Ultrasound examination of the fetal profile was carried out and the presence or absence of the nasal bone was noted immediately before karyotyping in 5918 fetuses at 11 to 13+6 weeks. Logistic regression analysis was used to examine the effect of maternal ethnic origin and...
متن کاملAltered Expression of 14-3-3ζ Protein in Spinal Cords of Rat Fetuses with Spina Bifida Aperta
BACKGROUND A large number of studies have confirmed that excessive apoptosis is one of the reasons for deficient neuronal function in neural tube defects (NTDs). A previous study from our laboratory used 2-D gel electrophoresis to demonstrate that 14-3-3ζ expression was low in the spinal cords of rat fetuses with spina bifida aperta at embryonic day (E) 17. As a member of the 14-3-3 protein fam...

Valproic Acid-Induced Skeletal Defects and Spina Bifida in Rat Fetuses
Purpose: Among antiepileptic drugs, valproic acid (VA) is a well known teratogenic agent. We previously reported that maternal (VA) administration of VA during critical periods of rat pregnancy can produce very rare CNS defect, syringomyelia. The purpose of the present study was whether VA can affect other organs, based on this finding, we studied the teratogenic effects of it on rat developing...
