Frozen-thawed boar sperm (FTS) has reduced motility and viability compared to cooled semen. Motility of FTS is related to in-vitro and in-vivo fertility, but this effect has not been determined in relation to the timing of ovulation. To test the effect of variable FTS motility in a multiple AI system, ...

Background:Exposure to maternal obesity or hyperglycemia increases the risk of obesity and poor glucose tolerance in the offspring. We hypothesized that maternal overnutrition in late pregnancy would result in (i) lower methylation in the promoter region of the cytosolic form of phosphoenolpyruvate carboxykinase (PEPCK-C; PCK1) and (ii) higher expression of ...

Overexposure of the developing fetus to glucocorticoids is hypothesised to be one of the key mechanisms linking early life development with later life disease. The maternal hypothalamic-pituitary-adrenal (HPA) axis undergoes dramatic changes during pregnancy and postpartum. Although cortisol levels rise threefold by the third trimester, the fetus is partially protected ...

Studies suggest that prenatal vitamin D status may be inversely associated with lower respiratory tract infections (LRTIs) early in life. Studies of prenatal vitamin D status and development of asthma have inconsistent findings. We examined the associations of maternal mid-pregnancy 25-hydroxyvitamin D [25(OH)D] level with the frequency of LRTIs by ...
