Background: Perfluoroalkyl Substances (PFAS) have drawn much attention due to environment bioaccumulation potential and their presence worldwide in human blood. Exposure to PFAS is suspected to induce endocrine-disrupting hormonal effects and may be involved in the development of type 2 diabetes (T2D). However, epidemiological evidence is scarce and inconsistent.Objective: We aimed to investigate the association of PFAS plasma levels on the risk of devel...

The placenta is a highly specialized organ, which ensures nutrient uptake, waste elimination, provides thermo-regulation, prevents passage of some xenobiotic molecules and regulates the quantity of thyroid hormones (TH) necessary for the fetal development. It is known, that even minor changes in maternal TH levels, can alter the fetal growth. Several factors can modify TH levels during pregnancy. Among them, increasing evidences show that prenatal exposure to persistent organi...

Thyroid hormones (TH) of maternal origin are critical for the proper fetal development, especially during early pregnancy. Even minor changes in maternal TH circulation can lead to various adverse outcomes. Recent studies found that the metabolites of thyroxine (T4) also play an important physiological role. For example, 3,5-diiodo-L-thyronine (T2) and 3,3′-diiodo-L-thyronine (rT2) can suppress the thyroid stimulating hormone (TSH) level ...
