1. Determining Methamphetamine in Urine by Molecularly Imprinted Polymer Assisted Paper Spray Ionization Mass Spectrometry
The usefulness of molecularly imprinted polymer assisted paper spray ionization mass spectrometry (MIP-PSI-MS) for the determination of methamphetamine in urine has been demonstrated. MIP-PSI-MS is a method in which a MIP is synthesized on the surface of a paper, producing a chemically selective paper surface with molecular recognition sites for a target ana

3. In silico Risk Assessment Studies of New Psychoactive Substances Derived from Amphetamines and Cathinones
The amount and variety of new psychoactive substances (NPS) are expanding, and there are difficulties in assessing their risks. In this regard, in silico methods are potentially useful to predict NPS properties faster and at a lower cost. In this work a quantitative structure-activity relationship (QSAR) model was used to verify the risk of drugs derived fro

4. Determinação de designer drugs em saliva por paper spray mass spectrometry
Determination of two drugs of abuse in saliva has been performed by Paper Spray Ionization Mass Spectrometry (PSI-MS) using a Molecularly Imprinted Polymer (MIP) coated paper as substrate. The method has been optimized for quantification of 3,4-methylenedioxy- N-methylamphetamine (MDMA) and methamphetamine, 3,4-methylenedioxyamphetamine (MDA) from synthetic

5. Protective Effects of Edaravone against Methamphetamine-Induced cardiotoxicity
ABSTRACT Methamphetamine (METH) is widely abused in worldwide. METH use could damage the dopaminergic system and induce cardiotoxicity via oxidative stress and mitochondrial dysfunction. Edaravone, a sedative-hypnotic agent, is known for it's antioxidant properties. In this study we used edaravone for attenuating of METH-induced cardiotoxicity in rats. The g

6. Determination of Amphetamine, Amfepramone and Fenproporex in Urine Samples by HPLC-DAD: Application to a Population of Brazilian Truck Drivers
Commercially available immunoassay tests are designed to detect the presence of amphetamine/methamphetamine or methylenodioxyamphetamines. However, it is known that Brazilian truck drivers also report the use of other illicit amphetamines, such as amfepramone and fenproporex. Thus, a method was developed and validated in order to quantify amphetamine-type st

7. Systematic review of N-acetylcysteine in the treatment of addictions
Objective: To conduct the first systematic literature review of clinical trials of N-acetylcysteine (NAC) for the treatment of substance abuse disorders and addictive behaviors. Methods: A search of the MEDLINE, Embase and PsycINFO databases was conducted. The inclusion criteria for the review were clinical trials that used NAC in the treatment of a disor

8. Determinação de estimulantes anfetamínicos no fluido oral : especificidade dos métodos de triagem e análise confirmatória
The Brazil stands out on the world as a major consumer of amphetamine-type stimulants (ATS), and several national studies have shown high prevalence in the consumption of these substances by professional drivers. Oral fluid has many advantages over the conventional biological fluids for monitoring ATS use on roads, and has been employed with this purpose in

9. Fatores envolvidos no desenvolvimento e expressão da sensibilização comportamental ao efeito estimulante do modafinil e metanfetamina. / Factors involved in development and expression of modafinil and methamphetamine-induced behavioral sensitization.
A sensibilização comportamental refere-se ao aumento progressivo do efeito estimulante induzido após repetidas administrações de drogas de abuso como cocaína e anfetaminas. Estudos prévios sugerem que o ambiente pareado aos efeitos destas drogas parece ter um importante envolvimento no fenômeno da sensibilização comportamental. Além disso, o trata

10. USO DE DROGAS PSICOTRÓPICAS POR POLICIAIS MILITARES DE GOIÂNIA E APARECIDA DE GOIÂNIA, GOIÁS, BRASIL / PSYCHOTROPIC DRUG USE BY POLICE MILITARY Goiânia and Aparecida de Goiânia, Goiás, BRAZIL
Licit drugs like alcohol, and illicit drugs such as marijuana, cocaine, opioids and amphetamines, are used by millions of people worldwide. The damage to health occurring due to the acute or chronic, and also due to psychomotor and behavioral changes that these substances cause the users. A situation that deserves special attention is the use of drugs in the

11. Effects of cocaine, methamphetamine and modafinil challenge on sleep rebound after paradoxical sleep deprivation in rats
Sleep loss is both common and critically relevant to our society and might lead to the abuse of psychostimulants such as amphetamines, cocaine and modafinil. Since psychoactive substance abuse often occurs within a scenario of sleep deficit, the purpose of this investigation was to compare the sleep patterns of rats challenged with cocaine (7 mg/kg, ip), met

12. A saliva como espécime biológico para monitorar o uso de álcool, anfetamina, metanfetamina, cocaína e maconha por motoristas profissionais / Saliva as biological specimen for screening the use of alcohol, amphetamine, methamphetamine, cocaine and marijuana by professional drivers
The consequences of car accidents in the traffic when psychoactive drugs are abused by professional drivers are of great concern of specialists in the subject as well as of the general population. For the Brazilian Traffic Code of 1997 to drive under the influence of alcohol, with blood leveI superior to six decigrams per liter, or any other psychoactive dru
