Proposal of 5-methoxy-N-methyl-N-isopropyltryptamine consumption biomarkers through identification of in vivo metabolites from mice
(Elsevier, 2017-07)
New psychoactive substances (NPS) are a new breed of synthetically produced substances designed to mimic the effects of traditional illegal drugs. Synthetic cannabinoids and synthetic cathinones are the two most common ...
Use of soft and hard ionization techniques for elucidation of unknown compounds by gas chromatography/time-of-flight mass spectrometry
(John Wiley, 2011-05-11)
Investigation of trace-level non-target compounds by gas chromatography/mass spectrometry (GC/MS) often is a challenging task that requires powerful software tools to detect the unknown components, to obtain the deconvoluted ...
Building an empirical mass spectra library for screening of organic pollutants by ultra-high-pressure liquid chromatography/hybrid quadrupole time-of-flight mass spectrometry
(John Wiley, 2011-01-30)
Hybrid quadrupole time-of-flight mass spectrometry (QTOF MS) has gained wide acceptance in many fields of chemistry, for example, proteomics, metabolomics and small molecule analysis. This has been due to the numerous ...
First nation-wide estimation of tobacco consumption in Spain using wastewater-based epidemiology
(Elsevier, 2020-11-01)
Wastewater-based epidemiology (WBE) has become a very useful tool to monitor a
population’s drug consumption or exposure to environmental and food contaminants. In this
work, WBE has been applied to estimate tobacco ...
Disruption of gut integrity and permeability contributes to enteritis in a fsh‑parasite model: a story told from serum metabolomics
(BMC, 2019)
Background: In the animal production sector, enteritis is responsible for serious economic losses, and intestinal
parasitism is a major stress factor leading to malnutrition and lowered performance and animal production ...
Fast determination of 40 drugs in water using large volume direct injection liquid chromatography–tandem mass spectrometry
(Elsevier, 2015)
This work describes a rapid analytical method based on direct sample injection of water samples for the simultaneous identification/quantification of 40 emerging compounds, including pharmaceuticals and drugs of abuse. The ...
Contributions of MS metabolomics to gilthead sea bream (Sparus aurata) nutrition. Serum fingerprinting of fish fed low fish meal and fish oil diets
(Elsevier, 2019-01-01)
The aim of this study was to evaluate the impact of fish meal (FM) and fish oil (FO) replacement by plant proteins and oils in the serum metabolome of two-year old gilthead sea bream (Sparus aurata) fed from early life ...
Comparative degradation of two highly consumed antihypertensives in water by sonochemical process. Determination of the reaction zone, primary degradation products and theoretical calculations on the oxidative process
(Elsevier, 2019)
This work compares the sonochemical degradation of losartan and valsartan (antihypertensives) in water. Initially, the suitable operational conditions of ultrasonic power density and frequency were established. Under such ...
Investigation of pharmaceuticals and their metabolites in Brazilian hospital wastewater by LC-QTOF MS screening combined with a preliminary exposure and in silico risk assessment
(Elsevier, 2020)
This work evaluates the occurrence of pharmaceuticals, with special emphasis on their metabolites, in raw hospital wastewater (HWW) using wide-scope screening based on liquid chromatography coupled to high resolution mass ...
Investigation of pharmaceuticals in processed animal by-products by liquid chromatography coupled to high-resolution mass spectrometry
(Elsevier, 2016-07)
There is an on-going trend for developing more sustainable salmon feed in which traditionally applied marine feed ingredients are replaced with alternatives. Processed animal products (PAPs) have been re-authorized as novel ...
