Mephedrone ("bath salt") pharmacology: insights from invertebrates.
Psychoactive bath salts (also called meph, drone, meow meow, m-CAT, bounce, bubbles, mad cow, etc.) contain a substance called mephedrone (4-methylcathinone) that may share psychostimulant properties with amphetamine and cocaine. However, there are only limited studies of the neuropharmacological profile of mephedrone. The present study used an established invertebrate (planarian) assay to test...
متن کاملModification of EN9 Steel Surface by Salt Bath Nitrocarburizing Process
Nitrocarburizing is a thermochemical treatment which involves the diffusional addition of nitrogen and carbon to the surface of ferrous materials. Usually carried out at temperatures within the ferritic phase field of the Fe-N-C system, i.e. below 593 °C, the treatment improves the resistance to scuffing through the development of a compound layer at the surface consisting predominantly of epsi...
متن کاملPreoxidation for colorimetric sensor array detection of VOCs.
A disposable preoxidation technique that dramatically improves the detection and identification of volatile organic compounds (VOCs) by a colorimetric sensor array is reported. Passing a vapor stream through a tube packed with chromic acid on silica immediately before the colorimetric sensor array substantially increases the sensitivity to less-reactive VOCs and improves the limits of detection...
متن کاملFlashback phenomenon and residual neurological deficits after the use of "bath salt" 3, 4- methylenedioxypyrovalerone.
