BACKGROUND As the placental vessels are dependent on the normal balance of procoagulant and anticoagulant mechanisms, inherited thrombophilia may be associated with fetal loss. OBJECTIVES We performed a prospective study to investigate the relation between inherited thrombophilia and fetal loss, and the influence of thromboprophylaxis on pregnancy outcome. PATIENTS AND METHODS Women were en...

We have investigated the regulation of translation during the period of rapid liver growth that occurs at the end of gestation in the rat. This work was based on our prior observation that fetal hepatocyte proliferation is resistant to the inhibitory effects of rapamycin, an inhibitor of the mammalian target of rapamycin (mTOR), a nutrient-sensing kinase that controls ribosome biogenesis and pr...

In order to elucidate the mechanisms that ensure survival of the allogeneic fetus, we are investigating the expression pattern of genes that are involved in peripheral self-tolerance in tissues at the maternal-fetal interface. Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) is a negative regulator of T cell activation and may modulate peripheral self-tolerance. Previously, we reported the ...

Atherosis of spiral arteries in uteroplacental beds from preeclamptic women resemble those of atherosclerosis, characterized by increased plasma lipids and lipoproteins. We hypothesized that: 1) lipoprotein receptors/transporters in the placenta would be upregulated in preeclampsia, associated with increased maternal and fetal lipoprotein concentrations; and 2) expression of these would be redu...

background: the discovery of circulating fetal dna in maternal blood led to the discovery of new strategies to perform noninvasive testing for prenatal diagnosis. objective: the purpose of the study was to detect fetal aneuploidy at chromosomes 13, 18, 21, x, and y by analysis of fetal cell-free dna from maternal blood, without endangering pregnancy. materials and methods: this retrospective st...

a full termed local ewe with the history of continuous straining with labored breathing for last 24 hours was presented. the animal was disinclined to move with tense and round abdomen which developed rapidly during last two weeks. caesarean section revealed hydrallantois accompanied by multiple fetal congenital abnormalities. the ewe was under observation for four weeks. metritis developed 12 ...

OBJECTIVE Impaired fetal growth is associated with cardiovascular disease in adulthood. The mechanisms of this association remain poorly described. We aimed to determine the associations of impaired fetal growth and preterm birth with cardiovascular risk factors and arterial health in a large cohort of young adults. METHODS AND RESULTS Carotid intima-media thickness, brachial flow-mediated di...

The objectives of this study were to determine the secretion patterns of prostaglandins (PG) and protein during mid- (Day 100) and late- (Day 140) pregnancy in the ewe and to ascertain whether that pattern is altered by in vitro heat shock. Explant cultures were prepared from intercaruncular endometrium, caruncular endometrium, fetal cotyledon and interplacentomal placenta. Cultures were incuba...

Poor quality of nutrition during fetal development is associated with adverse health outcomes in adult life. Epidemiological studies suggest that markers of fetal undernutrition are predictive of risk of the metabolic syndrome and CHD. Here we show that feeding a low-protein diet during pregnancy programmed the development of atherosclerosis in ApoE*3-Leiden mice. ApoE*3-Leiden mice carry a mut...

BACKGROUND Androgens and paracrine signaling from mesenchyme/stroma regulate development and disease of the prostate, and gene profiling studies of inductive prostate mesenchyme have identified candidate molecules such as pleiotrophin (Ptn). METHODS Ptn transcripts and protein were localized by in situ and immunohistochemistry and Ptn mRNA was quantitated by Northern blot and qRT-PCR. Ptn fun...
