Mass Spectrometric Evaluation of Mephedrone In Vivo Human Metabolism: Identification of Phase I and Phase II Metabolites, Including a Novel Succinyl Conjugate
(American Society for Pharmacology and Experimental Therapeutics (ASPET), 2015-02)
In recent years, many new designer drugs have emerged, including the group of cathinone derivatives. One frequently occurring drug is mephedrone; although mephedrone was originally considered as a “legal high” product, it ...
Determination of free amino acids in plants by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
(Royal Society of Chemistry, 2015)
A robust and sensitive method for identification (quantification and confirmation) of 19 free amino acids in the plant matrix, Stellaria media, based on liquid chromatography-electrospray ionization-tandem mass spectrometry ...
Advancing towards universal screening for organic pollutants in waters
(Elsevier, 2015)
Environmental analytical chemists face the challenge of investigating thousands of potential organic pollutants that may be present in the aquatic environment. High resolution mass spectrometry (HRMS) hyphenated to ...
Occurrence and potential transfer of mycotoxins in gilthead sea bream and Atlantic salmon by use of novel alternative feed ingredients
(Elsevier, 2015)
Plant ingredients and processed animal proteins (PAP) are suitable alternative feedstuffs for fish feeds in aquaculture practice, although their use can introduce contaminants that are not previously associated with marine ...
Use of CdS from Teaching-Laboratory Wastes as a Photocatalyst for the Degradation of Fluoroquinolone Antibiotics in Water
(MDPI, 2021-08-05)
Laboratory wastes containing Cd2+ and water polluted by pharmaceuticals represent an environmental concern. In this work, a proof concept, consisting of the use of teaching-laboratory wastes to synthesize CdS and its ...
Triacylglycerol Analysis in Human Milk and Other Mammalian Species: Small-Scale Sample Preparation, Characterization, and Statistical Classification Using HPLC-ELSD Profiles
(American Chemical Society, 2015-06)
In this work, a method for the separation of triacylglycerols (TAGs) present in human milk and from other mammalian species by reversed-phase high-performance liquid chromatography using a core–shell particle packed column ...
Optimization of electronic nose drift correction applied to tomato volatile profiling
(Springer, 2021)
E-noses can be routinely used to evaluate the volatile profile of tomato samples once the sensor drift and standardization issues are adequately solved. Short-term drift can be corrected using a strategy based on a ...
The key role of mass spectrometry in comprehensive research on new psychoactive substances
(John Wiley and SonsWiley, 2020-10-29)
New psychoactive substances (NPS) are a wide group of compounds that try to mimic the effects produced by the ‘classical’ illicit drugs, including cannabis (synthetic cannabinoids), cocaine and amphetamines (synthetic ...
Effects of different amendments (organic matter and hydrogel) on the actual evapotranspiration and crop coefficient of turf grass under field conditions
(John Wiley and SonsInternational Commission on Irrigation and Drainage (ICID)Wiley, 2020-11-16)
The irrigation schedule in arid areas has to be efficient in order to reduce losses due to evaporation and deep infiltration. Irrigation optimization poses the need to establish with precision the value of actual ...
Investigation of pharmaceutical metabolites in environmental waters by LC-MS/MS
(Springer, 2014)
Pharmaceuticals, once ingested, are commonly metabolized in the body into more polar and soluble forms. These compounds might not be completely removed in the wastewater treatment plants and consequently being discharged ...
