The poppy seeds contained 1.64 and 6.91ug/g of codeine and morphine, respectively. Only one urine sample from one volunteer showed a codeine concentration that was above the limit of quantitation (50ng/mL); this was 67.6ng/mL in the 4 h urine, and was well below the cutoff value of ...

No candidates showed other major psychiatric comorbidities and all of them were drug-naive, without using antibiotics, anti-inflammatory medicine, prebiotics, or anti-depressants in the last 2 months. After samples (serum, urine, and feces) collection, the depressive subjects were further treated ...
By allowing for direct injection of urine, liquid chromatography-tandem mass spectrometry (LC-MS-MS) with atmospheric-pressure chemical ionization has proven to be useful for analysis of drugs of abuse in urine. The purpose of this study was to evaluate this technique by direct screening for 23...
The urine sample is simply diluted in the buffer solution and injected directly in the microchip where the uric acid is separated and detected at the platinum electrode of a SU-8/Pyrex microfluidic chip. The microfluidic chips were used for several analyses with a good performance and precision,...
