Hair of young subjects (N = 36) suspected for drug abuse was analysed for morphine, codeine, heroin, 6-acetylmorphine, cocaine, methadone, amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA), and 3,4-methylenedioxyethylamphetamine (MDEA). The analysis of morphine, codeine, heroin, 6-acetylmorphine, cocaine, and methadone in hair included i...

Raman spectroscopy with far-red excitation has been used to study seized, tableted samples of MDMA (N-methyl-3,4-methylenedioxyamphetamine) and related compounds (MDA, MDEA, MBDB, 2C-B and amphetamine sulfate), as well as pure standards of these drugs. We have found that by using far-red (785 nm) excitation the level of fluorescence background even in untreated seized samples is sufficiently lo...

Absorption is one of the most established techniques to capture CO2 from natural gas and post-combustion processes. Nevertheless, absorption process frequently suffers various operational issues, including foaming. The main objective current work elucidate effect degradation product on foaming behavior in methyldiethanolamine (MDEA) piperazine (PZ) solution evaluate antifoaming performance poly...

The object of this work is solubility correlation and prediction of CO2 and H2S in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (eCSW EoS) (Haghtalab, A.,Mazloumi, S. H., (2010), Electrolyte Cubic Square-Well Equation of State for Computation of the Solubility CO2 and H2S in Aqueous MDEA Solutions,  Ind. Eng. Chem. Res.,49,6221-623). The eEoS systemati...

CO2 sorption–desorption cycles with a methyldiethanolamine (MDEA)/piperazine (PZ) blend have been performed rotoevaporator. Similar to other separation technologies, the heating involved in MDEA/PZ solvent regeneration is most energy-intensive step overall process. Thus, this study investigated desorption kinetics under low-pressure (<200 mbar) and low-temperature conditions range from 308 3...

In this study, IC50 shift and time-dependent inhibition (TDI) experimentswere carried out tomeasure the ability of amiodarone (AMIO), and its circulating human metabolites, to reversibly and irreversibly inhibit CYP1A2, CYP2C9, CYP2D6, and CYP3A4 activities in human liver microsomes. The [I]u/Ki,u values were calculated and used to predict in vivo AMIO drug-drug interactions (DDIs) for pharmace...
