Developing Potential Candidates of Preclinical Preeclampsia.

The potential for developing molecules of interest in preclinical preeclampsia from candidate genes that were discovered on gene expression microarray analysis has been challenged by limited access to additional first trimester trophoblast and decidual tissues. The question of whether these candidates encode secreted proteins that may be detected in maternal circulation early in pregnancy has been investigated using various proteomic methods. Pilot studies utilizing mass spectrometry based proteomic assays, along with enzyme linked immunosorbent assays (ELISAs), and Western immunoblotting in first trimester samples are reported.

The -93T/G LPL Promoter Polymorphism Is Associated With Lower Third-Trimester Triglycerides in Pregnant African American Women.

Background: Hypertriglyceridemia is a risk factor for cardiovascular disease and several pregnancy complications. Lipoprotein lipase (LPL) genetic variation modulates nonpregnancy plasma triglycerides, but its effects during pregnancy are unknown. The G allele of the LPL -93T/G promoter polymorphism is 16-23 times more prevalent in Blacks than in Whites, contributing to lower triglycerides in nonpregnant African Americans by increasing LPL expression.

Brain stimulation paired with novel locomotor training with robotic gait orthosis in chronic stroke: a feasibility study.

Objectives: 1) To investigate the feasibility of combining transcranial direct current stimulation (tDCS) to the lower extremity (LE) motor cortex with novel locomotor training to facilitate gait in subjects with chronic stroke and low ambulatory status, and 2) to obtain insight from study subjects and their caregivers to inform future trial design.

Methods: Double-blind, randomized controlled study with additional qualitative exploratory descriptive design. One-month follow-up.

Cardiovascular system during the postpartum state in women with a history of preeclampsia.

In subjects with previous preeclampsia, differences in cardiovascular and/or blood biochemical parameters are present in the nonpregnant state, and a simultaneous assessment of multiple derived indices better differentiates between women with or without previous preeclampsia. We examined 18 previous preeclamptic and 50 previous uncomplicated pregnancies, ≈16 months postpartum. Cardiovascular assessment included the following: (1) systemic hemodynamics and mechanics (Doppler echocardiography, tonometry, and oscillometric sphygmomanometry); (2) endothelial function (plethysmography); (3) left ventricular properties (echocardiography); and (4) blood biochemical analyses.
