Preterm deliveries that result from multiple pregnancies associated with assisted reproductive technologies in the USA: a cost analysis.

Purpose Of Review: Simultaneous transfer of multiple embryos in an assisted reproductive technology (ART) cycle results in a high rate of multiple pregnancy. Besides the medical complications associated with multiple pregnancy, the financial burden of the resultant preterm infants is also substantial. The current review evaluates the costs associated with the care of preterm infants that are born as a result of ART-associated multiple pregnancies.

A1 adenosine receptors mediate hypoxia-induced ventriculomegaly.

Periventricular leukomalacia is characterized by a reduction in brain matter and secondary ventriculomegaly and is a major cause of developmental delay and cerebral palsy in prematurely born infants. Currently, our understanding of the pathogenesis of this condition is limited. In animal models, features of periventricular leukomalacia can be induced by hypoxia and activation of A1 adenosine receptors (A1ARs).

Estradiol suppresses vascular monocyte chemotactic protein-1 expression during early atherogenesis.

Objective: This study was undertaken to determine whether estrogen down-regulates vascular monocyte chemotactic protein-1 expression during the development of atherosclerosis in vivo and to identify the cellular localization of monocyte chemotactic protein-1 expression under baseline conditions and in response to atherogenic stimuli.

Study Design: Female, homozygous low-density lipoprotein-receptor-deficient mice (n = 68) in a C57BL/6 background underwent ovariectomy, were implanted subcutaneously with 17beta-estradiol or placebo pellets, and were changed to a high cholesterol (1.25%) diet.
