A reply to ‘Metabolic effects of sapropterin treatment in autism spectrum disorder: a preliminary study'
Frye et al.1 published a study in Translational Psychiatry that indicated that treatment with sapropterin, which is a synthetic form of tetrahydrobiopterin (BH4), improved metabolic outcomes in patients with autism spectrum disorder (ASD). They explained that BH4 is a critical co-factor for the production of precursors of many monoamine neurotransmitters, including dopamine (DA)2 and norepinephrine (NE),3 and is vital in nitric oxide (NO) production. The author of this letter has published an ecological investigation that may shed light on the existence of BH4 in ASD and why supplementation appears to ameliorate behavioral and metabolic outcomes in ASD, as shown by Frye et al.1
Heavy metal adsorption from industrial wastewater by PAMAM/TiO2 nanohybrid: Preparation, characterization and adsorption studies
Abstract This study investigates the removal of heavy metals from industrial wastewater using TiO 2 nanoparticles modified with poly-amidoamine dendrimer (PAMAM, G 4 ). The metal ions Cu 2 + , Pb 2 + , and Cd 2 + were selected as model pollutants. FTIR, SEM, BET surface area and Zeta potential measurements, and Dispersion Observing methods have been employed for characterizing the synthetic nanohybrid and these techniques indicated that the PAMAM loaded on to TiO 2 have been favorably synthesized. The effects of several parameters including initial metal ion concentration, temperature, pH solution, the nanohybrid dosage and contact time were studied. The experimental data were analyzed using equilibrium isotherm and kinetics models. The adsorption process was studied using isotherm, kinetics, and thermodynamics models. The analysis shows that the Langmuir isotherm and pseudo-second-order kinetics are appropriate models for the adsorption process. The thermodynamic parameters illustrate that the absorption is endothermic and spontaneous. The findings suggest that the nanohybrid is a good super absorbent for the removal of heavy metals from industrial effluents.
