Placental magnetic resonance imaging in chronic hypertension: A case-control study.

abstract：OBJECTIVE:Increasing evidence suggests an association between periodontal disease and low birthweight (LBW); however the underlying molecular mechanisms are yet to be fully elucidated. In this study, we performed a microarray analysis to observe the human placental trophoblast-like BeWo cells response to lipopolysaccha...
