Sensor portátil detecta canabinoides sintéticos em cigarros eletrônicos e fluidos biológicos
<p><strong>José Tadeu Arantes | Agência FAPESP</strong> – Mesmo sem conter nenhuma substância ilícita, o líquido dos cigarros eletrônicos pode causar sérios danos à saúde. Em muitos casos, a concentração de nicotina nesses produtos é várias vezes superior à encontrada nos cigarros convencionais – o que favorece a rápida instalação da dependência. Além disso, como os […]
A dive into the new psychoactive substances: a review of the use of zebrafish (Danio rerio) as an in vivo model
Abstract New psychoactive substances (NPS) are a broad category of drugs that pose public health risks and have poorly characterized pharmacological properties. Further studies are critical for risk assessment, toxicological profiling, and intoxication management. artigo completo: https://www.tandfonline.com/doi/full/10.1080/01480545.2025.2548873
Development and validation of quantitative analytical method for 50 drugs of antidepressants, benzodiazepines and opioids in oral fluid samples by liquid chromatography–tandem mass spectrometry
Abstract Purpose We developed and validated a method for quantitative analysis of 50 psychoactive substances and metabolites (antidepressants, benzodiazepines and opioids) in oral fluid samples using simple liquid–liquid extraction procedure followed by liquid chromatography–tandem mass spectrometry (LC–MS/MS). artigo completo: https://link.springer.com/article/10.1007/s11419-020-00561-8
Green analytical toxicology method for determination of synthetic cathinones in oral fluid samples by microextraction by packed sorbent and liquid chromatography–tandem mass spectrometry
We developed and validated a method for quantitative analysis of ten synthetic cathinones in oral fluid (OF) samples, using microextraction by packed sorbent (MEPS) for sample preparation followed by liquid chromatography‒tandem mass spectrometry (LC‒MS/MS). OF samples were collected with a Quantisal™ device and 200 µL was extracted using a C18 MEPS cartridge installed on a […]
