There were no significant differences between the two groups in terms of age or parity, but there was a significant difference in the gestation at delivery as patients with pre-eclampsia delivered early compared to normal pregnant women.
There was no significant difference in the gestation at which the earliest pregnancy weight was measured (14.3 weeks (SD 7.0) for cases and 13.8 weeks (SD 7.1) for controls p = 0.54).
Also there was no significant difference in the mean gestation at haemoglobin testing (P=0.54), which was 32.0 weeks (SD 2.6), 31.9 weeks (SD 2.8), and 32.2 weeks (SD 3.1) for the folic acid, iron-folic acid, and multiple micronutrient groups, respectively.
When babies who were judged to have cords that were too short to reach the trolley were compared with babies who were placed on the trolley, there were no statistically significant differences in gestation or the proportion of babies born by caesarean section.
The difference in average number of generations reflects evolved differences in gestation time, with the populations that evolved from Ancestor2 having longer generations because they spend more time performing logic functions.
Despite obvious similarities between the donkey and horse placenta, specific morphological features do exist, and are possibly related to the differences in length of gestation.
However, ethnical differences in mid gestation have been found for femur measurements in some studies [ 10, 18- 20], and we therefore recommend fetal age assessment in the second trimester to be based primarily on fetal head-measurements.
In an earlier review, Ngun and Vilain cited evidence that methylation may be determined by subtle differences in the environment each fetus experiences during gestation, such as their exact locations within the womb and how much of the maternal blood supply each receives.
Genome-wide microarray analysis was used to identify differences in the gene expression profiles of late gestation and early postnatal total pancreas tissue from wild type and Hnf6 transgenic animals.
It is clear that this analysis will need to be repeated in another population, particularly as the difference in the effect of gestation on skeletal size and fat is not widely reported in the literature.
