Microbiological quality and antimicrobial resistance of Escherichia coli and Staphylococcus aureus isolated from conventional and organic “Arzúa-Ulloa” cheese
(Taylor and Francis, 2009)The presence of Escherichia coli, Staphylococcus aureus, Listeria monocytogenes and Salmonella spp. was tested in 184 cheese samples included in the Protected Designation of Origin ‘‘Arzu´a-Ulloa’’. From these samples, ... -
Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf
(Elsevier, 2020)Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 ... -
Migration studies of two common components of UV-curing inks into food simulants
(MDPI, 2019)The Rapid Alert System for Food and Feed (RASFF) has reported many cases of different UV curing inks components in foodstuffs during the last few years. These contaminants reach foodstuffs mainly by set-off, their principal ... -
Milk Microbiota: A Source of Antimicrobial-Producing Bacteria with Potential Application in Food Safety
(MDPI, 2021)Antimicrobial and biocide resistance is a major public health problem today. Therefore, one of the main scientific challenges nowadays is the search for alternatives to these substances. One of these potential alternatives ... -
Mimicking human ingestion of microplastics: oral bioaccessibility tests of bisphenol A and phthalate esters under fed and fasted states
(Elsevier, 2022)Notwithstanding the fact that microplastic fragments were encountered in the human stool, little effort has been geared towards elucidating the impact of chemical additives upon the human health. In this work, standardized ... -
Miniaturized matrix solid-phase dispersion for the analysis of ultraviolet filters and other cosmetic ingredients in personal care products
(MDPI, 2019)A method based on micro-matrix solid-phase dispersion (μ-MSPD) followed by gas-chromatography tandem mass spectrometry (GC–MS/MS) was developed to analyze UV filters in personal care products. It is the first time that ... -
Model for Vaccine Design by prediction of B-Epitopes of IEDB given perturbations in peptide sequence, in vivo process, experimental techniques, and source or host organisms
(Hindawi, 2014)Perturbation methods add variation terms to a known experimental solution of one problem to approach a solution for a related problem without known exact solution. One problem of this type in immunology is the prediction ... -
Modeling Dispersal of UV Filters in Estuaries
(American Chemical Society, 2019-01-11)Lagrangian ocean analysis, where virtual parcels of water are tracked through hydrodynamic fields, provides an increasingly popular framework to predict the dispersal of water parcels carrying particles and chemicals. We ... -
Modification of glucosinolates in turnip greens (Brassica rapa subsp. rapa L.) subjected to culinary heat processes
(Taylor&Francis, 2016-05-06)The consumption of Brassica vegetables has been related to improved health benefits due to their phytochemical components, such as glucosinolates, that induce a variety of physiological functions. Glucosinolate levels can ... -
Molecular characterization of lactic acid bacteria isolated from beef and stored using vacuum-packaging and advanced vacuum skin packaging systems
(Taylor & Francis, 2011)A total of 91 lactic acid bacteria (LAB) were isolated from 50 beef samples, 25 packaged by traditional vacuum packaging and 25 packaged using advanced vacuum skin packaging. The isolated LAB were identified using 16S rRNA ... -
