Background: Hypertensive pregnancy disorders are associated with adverse cardiac remodeling, which can fail to reverse postpartum in some women. The Physician Optimized Postpartum Hypertension Treatment trial demonstrated improved blood pressure control, while the cardiovascular system recovers postpartum, associates with persistently reduced blood pressure. We now report the impact on cardiac remodeling.

Kinetics of the Reaction of Ferrous Ions with Hydroxyl Radicals in the Temperature Range 25-300 °C The kinetics and mechanism of the reaction between OH radicals and ferrous ions in the temperature range 25-300 °C were studied using pulse radiolysis. At temperatures < 150 °C the rate of reaction is essentially independent of temperature, while at temperatures > 150 °C the activation energy is 43.44 kJ mol-1.

Pulsed electron radiolysis was used to determine the chemical reaction kinetics and Arrhenius parameters for iron(II) reactions in aqueous solutions under irradiation. The second-order Fe2+ reactions with the hydrated electron (eaq–) and the perhydroxyl radical (HO2•), arising from water radiolysis, were measured to high temperatures using custom-built flow-through cells with a multichannel optical detection system.
