Increased homocysteine is associated with the pregnancy complication preeclampsia and with later-life cardiovascular disease. Although elevated homocysteine persists after pregnancy, the vascular changes of preeclampsia abate with delivery, and cardiovascular disease occurs decades later. This suggests the vasculature during pregnancy may manifest increased sensitivity to homocysteine. We used ...

An infectious microorganism, identified as Listeria monocytogenes, has been isolated from the bloodstream of pregnant mice fed a diet containing Pinus ponderosa needles. When the isolate was injected into pregnant mice, reproductive dysfunction and other changes, including speckled livers, spleen atrophy, and hemorrhagic intestines, appeared to mimic the signs of the disease in pregnant mice fe...

Severe malaria, including cerebral malaria (CM) and placental malaria (PM), have been recognized to have many of the features of uncontrolled inflammation. We recently showed that in mice genetic susceptibility to the lethal inflammatory autoimmune disease, systemic lupus erythematosus (SLE), conferred resistance to CM. Protection appeared to be mediated by immune mechanisms that allowed SLE-pr...

introduction: chlorpyrifos (cpf), an organophosphate insecticide, was evaluated for potential teratogenic effects in mice. a single oral dose of insecticide (i.e. 72, 36 18 or 9 mg/kg) was given to the pregnant females on gestation day6 (gd6). these doses correspond 50, 25, 12.5 and 6.25% to the calculated ld50 value (144 mg/kg) for the pregnant mice. no signs of overt toxicity were observed at...

Background: Integrins are heterodimeric glycoprotein receptors that regulate the interaction of cells with extracellular matrix and may have a critical role in implantation. The aim of this study was to investigate the effect of ovulation induction on the expression of α4, αv, β1, and β3 integrins in mouse blastocyst at the time of implantation. Methods: The ovarian stimulated and non-stimulate...

Intestinal uptake (U) and transport (T) of 50Fe from a 1-mug oral dose was studied in the mouse. U increased to a similar degree in both pregnant and iron-deficient animals. The increase in T was greater in pregnant than in iron-deficient mice. In iron-loaded pregnant mice, U increased to levels found in pregnant animals, whereas T increased, but by a lesser amount. Termination of pregnancy by ...

During the growth of the pregnant uterus of inbred Balb/c mice uterine colony-stimulating factor (CSF) content increased 800-fold. This corresponded to a 75-fold increase in CSF concentration. The size of the increase was the same in the uteri of inbred Balb/c mice and the uteri of F1 hybrid C57Bl/Balb/c mice mated with F1 males. It was about four times greater in these uteri than it was in the...
