Both an increased rate of embryonic, foetal and perinatal losses, and the occurrence of deviations in foetal and placental development are associated with bovine pregnancies obtained from in vitro produced embryos. This thus requires for a more accurate and frequent monitoring of foetal and maternal functions during pregnancies. Such approaches will enable to establish the period during which t...

Laurence and Abbott (1956) published a description of a micro-method for the estimation of serum bilirubin by the indirect diazo reaction. They indicated that two patterns of colour development are obtainable with foetal and adult sera from cases of severe haemolytic disease due to Rh incompatibility and from obstructive jaundice due to blockage of the common bile duct from carcinoma of the hea...

AIMS To examine the causes of variability in the effect of maternal drinking on the foetus, with particular reference to the pattern, frequency and duration of the period of drinking, differences in maternal, foetal and placental metabolism of ethanol/acetaldehyde, and genetic factors. METHODS Narrative review of published studies of the pathogenesis of foetal alcohol syndrome (FAS) with emph...

Cellular and subcellular immunolocalization of aldose isozymes and alpha-foetoprotein (AFP) was performed in rat liver during the different stages of carcinogenesis induced by 3'-methyl-4-dimethylaminoazobenzene. During the early stages, double-labelling experiments showed that oval and transitional cells that expressed foetal aldolases did not contain adult aldolase B; this isozyme was only fo...

The data presented clearly suggest that relative amounts of mRNAs for elastins a, b and c are developmentally regulated in foetal-calf nuchal ligament and aorta and that this regulation is tissue-specific. In nuchal ligament, at earlier stages of foetal development, the relative amounts of mRNAs for elastins a and b are very low. After the foetal age of about 6 months the relative amount ofmRNA...
