In this paper we are presenting several expert systems built for the identification of illicit amphetamines using GC-FTIR spectra, GC-MS spectra and a hybrid GC-FTIR GC-MS spectral database (concatenated spectral database). The systems were built using Artificial Neural Networks (ANN), and are dedicated to the recognition of amphetamines. The database is formed by chemical compounds with toxico...

It has been shown by WVeiss and Laties'> that amphetamines, besides being central stimulants, not only improve physical performance but also a motivation to perform the work better, and more so when fatigue is setting in. Prolonged exercise with the concomitant relative muscular anoxia causes accumulation of lactic acid in blood and tissues because its uptake by liver is slower than its rate of...

BACKGROUND The CNS stimulatory agents amphetamine and methamphetamine are often detected in blood samples from apprehended subjects driving under the influence of drugs. MATERIAL AND METHODS Relevant literature was identified through searches in PubMed and Google Scholar. The current state of knowledge regarding effects of amphetamines on traffic behaviour is reviewed and discussed. RESULTS...

IMPLICATIONS Amphetamines are powerful, sympathomimetic amines that, when used chronically, can profoundly effect a patient's cardiovascular stability during anesthesia and surgery. Amphetamines are the third most widely abused class of drugs in the United States. They also have legitimate medical use for attention deficit disorder with hyperactivity, exogenous obesity, and narcolepsy. We repor...

Weight loss is one of the most researched and marketed topics in American society. Dietary regimens, medications that claim to boost the metabolism, and the constant pressure to fit into society all play a role in our patient's choices regarding new dietary products. One of the products that are well known to suppress appetite and cause weight loss is amphetamines. While these medications suppr...

MAIN OBJECTIVE To compare the incidence rates of serious cardiovascular events in adult initiators of amphetamines or atomoxetine to rates in non-users. METHODS This was a retrospective cohort study of new amphetamines (n=38,586) or atomoxetine (n=20,995) users. Each medication user was matched to up to four non-users on age, gender, data source, and state (n=238,183). The following events we...
