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
Growth and Characterization of β-RDX Single-Crystal Particles
1,3,5-Trinitrohexahydro-s-triazine (RDX) single-crystal particles crystallized in the β phase have been successfully grown by sublimation–recrystallization. Synchrotron X-ray diffraction results confirm that the recrystallized products are β-RDX single crystals. Compared to the traditional solution deposition methods, the sublimation method used in this work breaks through the mass limitations during the growth of β-RDX. The distribution of α- and β-RDX on different substrates reveals that hydrophilic substrates are prone to grow β-RDX single crystals and that hydrophobic substrates prefer α-RDX single crystals. The sublimation rate dominates the growth of pure β-RDX. The mechanisms of the phase transition from β-RDX to α-RDX during the process of sublimation–recrystallization have been studied. The current results can promote the potential application of β-RDX in the propellant, explosives, and military fields.
