OBJECTIVES This study was carried out to examine the performance of a contingent policy in first-trimester screening for trisomy 21, in which the estimated risk was first derived by a combination of maternal age, fetal nuchal translucency (NT) thickness, presence/absence of the nasal bone, blood flow in the ductus venosus or flow across the tricuspid valve, and biochemical testing was carried o...

OBJECTIVE To investigate if ductus venosus (DV) pulsatility index for veins (PIV) and a-wave measurements can increase the accuracy of first-trimester Down syndrome screening in a high-risk population. METHODS The database of our fetal medicine unit was searched for all cases at increased first-trimester Down syndrome risk. Multivariable logistic regression was used to construct a prediction ...

OBJECTIVES The morphology of region umbilical vein, umbilical sinus and ductus venosus of human fetuses have been investigated. MATERIAL AND METHODS 26 human fetuses between 20 and 40 weeks' gestation were examined by morphological methods. The umbilical vein, DV and the portal vein were obtained after termination of gestation. Tissue samples have been fixed in phormaldehyde solution (pH 7,2)...

Our current, still limited, understanding of the comparative biology and evolution of polydnaviruses (PDVs) is reviewed, especially in the context of the possible origins of these parasitoid viruses and of their coevolution with carrier wasps. A hypothetical scenario of evolution of PDVs from ascovirus (or ascovirus-like) ancestors is presented, with examples of apparent extant transitional for...
