Report on a New Opioid NPS: Chemical and In Vitro Functional Characterization of a Structural Isomer of the MT-45 Derivative Diphenpipenol.

for the protonated molecule of m/z 389.2264, with two prominent fragment ions (m/z 91.0567 and 150.0937), which were not reported in earlier literature describing MT-45 derivatives. The chemical ...

Risk assessment of nitrate and nitrite in feed

the risks to animal health related to nitrite and nitrate in feed. For nitrate ion, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) identified a BMDL10  of 64 mg nitrate/kg body weight ...

Urinary sodium and iodine concentrations among Belgian adults: results from the first national Health Examination Survey.

and ion selective electrodes respectively. Tanaka and INTERSALT equations were used to predict 24-h urinary sodium excretion using sodium and creatinine concentration in spot samples, sex, and measured ...

Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food

mass accuracy and retention times in a pesticide screening method that integrates all the features offered by coupling ultra‐performance liquid chromatography (UPLC) with ion mobility mass spectrometry ...

Estimating the Reliability of Low-Abundant Signals and Limited Replicate Measurements through MS2 Peak Area in SWATH

ions mass spectrometry (SWATH- MS) provides large-scale protein quantification with high accuracy and selectivity. Nevertheless, reliable quantification of low-abundant signals in complex samples remains ...
