... between 09:00 and 10:00, the pregnant dams were anaesthetised with isoflurane by inhalation (4% in oxygen at 2 L/min), and maternal blood was collected by cardiac puncture. Dams were killed by cervical dislocation after which placentas and fetuses were harvested rapidly. Individual fetal blood samples...

.... Glycine may become conditionally essential, as its rate of endogenous formation is inadequate to meet metabolic needs, and may be limiting for the normal development of the fetus. In the present study, five groups of Wistar rats were provided during pregnancy with one of five diets: a control diet...

...D. J. P. BARKER 1. Many human fetuses have to adapt to a limited supply of nutrients. In doing so they permanently change their structure and metabolism. 2. These ‘programmed' changes may be the origins of a number of diseases in later life, including coronary heart disease and the related...

... ). There was no change in the umbilical ( A - V ) concentration of oxytocin if morphine had been given to the mother in labour; this applied to fetuses delivered vaginally or by Caesarean section.

... system, known to be induced in rat fetuses exposed to low protein diets [28], or the vascular system could mediate the observed hypertension. Linear regression analysis indicated a relationship between the reduced protein intakes of the mothers, and the systolic blood pressure of the offspring. Although...
