(+/-)3,4-Methylenedioxymethamphetamine (MDMA, "Ecstasy"), a ring-substituted amphetamine derivative first synthesized in 1914, has emerged as a popular recreational drug of abuse over the last decade. Pharmacological studies indicate that MDMA produces a mixture of central stimulant and psychedelic effects, many of which appear to be mediated by brain(More)
Theoretical considerations and recent experimental data have prompted an investigation of the neurotoxicological properties of the 6-hydroxydopamine analogue 2-(methylamino)-1-(2,4,5-trihydroxyphenyl)propane (5) and its possible precursor 1-[2-hydroxy-4,5-(methylenedioxy)phenyl]-2- (methylamino)propane (4), potential metabolites of the serotonergic(More)
These studies assessed the neurotoxic potential of N-methyl-1-(4-methoxyphenyl)-2-aminopropane (para-methoxymethamphetamine; PMMA), an amphetamine analog that has surfaced in the illicit drug market. Repeated subcutaneous injections of PMMA caused lasting, dose-related reductions in regional brain concentrations of serotonin (5-HT) and 5-hydroxyindoleacetic(More)
N-Methylation separates methamphetamine's neurotoxic and pharmacologic effects. In particular, N-methylation eliminates methamphetamine's neurotoxic activity while preserving its behavioral pharmacologic activity. The purpose of the present studies was to determine whether N-methylation could also be used to separate fenfluramine's neurotoxic and(More)
During production of How To Train Your Dragon 2 we were motivated to improve our technology for character effects such as ropes, chains and cloth. Our goal was to reduce artist iteration time for simulation work while retaining the flexibility required for art direction. Inspired by the success of position-based dynamics in games, we implemented a new(More)
In Mileena Malign, a frightened doll moves helplessly to her own destruction at the hands of the very person who should love and protect her. In this cycle of abuse, our heroine doll is destroyed repeatedly, unable to escape the consequences of abuse, even in her dreams.
