Article Snippet: The objective of the present study was to investigate the bioavailability of aflatoxins (AFs) from fish, and chicken and rabbit livers using an in vitro dialyzability approach.. Ultrahigh-performance liquid chromatography−tandem mass spectrometry (UHPLC-MS/MS) was used to assess the aflatoxin content in samples, as well as in dialyzate and residue fractions after the in vitro procedure.. A vortex-assisted dispersive liquid−liquid microextraction (VALLME) technique was used for preconcentrating AFs before determination. Article Title: Ultrasound assisted combined molecularly imprinted polymer for the selective micro-solid phase extraction and determination of aflatoxins in fish feed using liquid chromatography-tandem mass spectrometry. Article Snippet: A combined procedure based on using ultrasounds for target isolation followed by porous membraneprotected micro solid phase extraction using a molecularly imprinted polymer as an adsorbent has been developed as a highly selective extraction and clean-up procedure for isolating aflatoxins B1, B2, G1, and G2 from fish feed before ultra-high-performance liquid chromatography tandem mass spectrometry determination.. Polymeric adsorbent beads have been synthesized by the precipitation polymerization method which guarantees a homogeneous particles size distribution and the integrity of the generated imprinted cavities.. In addition, polymerization was performed using a higher proportion of organic solvent (toluene) in the porogen mixture, which generates MIP particles adequate for interacting with targets dissolved in organic (hydro-organic) mixtures (extracts from fish feed). Article Title: Ultrasound assisted membrane-assisted solvent extraction for the simultaneous assessment of some drugs involved in drug-facilitated sexual assaults by liquid chromatography-tandem mass spectrometry. Article Snippet: Analysis was performed using a 3200 QTRAP LC-MS/MS system from ABSciex (Concord, Canada) equipped with an electrospray ionization source, a Flexar FX-15 LC binary pump with integrated vacuum degasser (Perkin Elmer, Waltham, MA, USA), a Flexar LC autosampler (Perkin Elmer), and a Article Title: The probability to detect cocaine, methylecgonine, cinnamoylcocaine, hygrine and cuscohygrine in urine samples of coca leaves chewers after six years Article Snippet: a Toxicology Laboratory, San Martín 565, Cipolletti, RN, Patagonia, Argentina bDepartment of Analytical Chemistry, Nutrition and Bromatology, Faculty of Chemistry, University of Santiago de Compostela, Santiago de Compostela, Spain c Forensic Sciences Institute "Luís Concheiro" (INCIFOR), Department of Pathologic Anatomy and Forensic Sciences, Faculty of Medicine, Universidade de Santiago de Compostela, Rúa de San Francisco, s/n, 15782 Santiago de Compostela, Spain Article Title: Combining ultrasound-assisted extraction and vortex-assisted liquid-liquid microextraction for the sensitive assessment of aflatoxins in aquaculture fish species. Article Snippet: Funding information Secretaria Xeral de Investigación e Desenvolvemento, Xunta de Galicia, Grant/Award Numbers: 6RC2014/2016, ED431C2018/19, ED431E2018/08 Although aflatoxins contamination in feedstuff is a well-known problem, and hence these residues are controlled in poultry products, there is scarce information regarding the presence of these toxic substances in aquaculture fish, facilities that use several feedstuff for fish breeding.. A simple, rapid, and sensitive method has been therefore developed for aflatoxins (B1, B2, G1, and G2) assessment in aquaculture products by combining ultrasound probe-assisted extraction and vortex-assisted liquid–liquid microextraction as a sample pretreatment, and high-performance liquid chromatography-tandem mass spectrometry as a separation/detection system.. Aflatoxins were extracted from fish flesh/liver with a 60:40 acetonitrile/aqueous phosphate buffer (pH 7.0) mixture before preconcentration and clean-up by vortex-assisted liquid–liquid microextraction under the following optimized conditions: 5.0 mL of fish extract at pH 7.0 and NaCl at 0.5% (w/v), 400 μL of chloroform as extracting solvent, and vortex shaking at 2000 rpm for 1 min.
