    The Role of Pro- and Antioxidant Systems in the Development of Placental Dysfunction in Human Pregnancy

    The pro-and antioxidant systems of the human placenta have been studied in its central and peripheral areas in the state of dysfunction. It has been shown that the intensity of free-radical oxidation (FRO) is ...
