PURPOSE Methylmalonic acidemias are inherited metabolic disorders characterized by methylmalonate (MMA) accumulation and neurologic dysfunction, including seizures. It is known that metabolic crises in affected patients are precipitated by infections. Although growing evidence supports that inflammation facilitates seizures, it is not known whether(More)
The aim of this study was to investigate the effects of phenylalanine on oxidative stress and some metabolic parameters in astrocyte cultures from newborn Wistar rats. Astrocytes were cultured under four conditions: control (0.4 mM phenylalanine concentration in the Dulbecco’s Modified Eagle Medium (DMEM) solution), Phe addition to achieve 0.5, 1.0 or 1.5(More)
Monosialoganglioside (GM1) is a glycosphingolipid present in most cell membranes that displays antioxidant and neuroprotective properties. It has been recently described that GM1 induces vasodilation. However, the mechanisms underlying GM1-induced vasodilation were not evaluated to date. Therefore, in this study we investigated whether the nonspecific NOS(More)
Phenylketonuria (PKU) is the most frequent inborn error of metabolism. It is caused by deficiency in the activity of phenylalanine hydroxylase, leading to accumulation of phenylalanine and its metabolites. Untreated maternal PKU or hyperphenylalaninemia may result in nonphenylketonuric offspring with low birth weight and neonatal sequelae, especially(More)
