Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
spectrometry (spICP- MS). The evaluation of selected sample preparation protocols allowed identifying and optimizing the critical factors that determine the measurement of the particle size distribution by TEM. ...
Assessing the receptor-mediated activity of PAHs using AhR-, ERα- and PPARγ- CALUX bioassays
reported to have carcinogenic and/or mutagenic properties, another possible negative health impact is their endocrine disrupting potential. Therefore, the aim of this study was to determine both the ...
Detection strategy targeting a chloramphenicol resistance gene from genetically modified bacteria in food and feed products
First, the potential presence of the AMR gene is detected by real-time PCR. Next, its full-length is evaluated by a nested- PCR amplifying a large fragment of its sequence to determine the risks of likely ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
chromatography – tandem mass spectrometry (UHPLC- MS / MS) method for the simultaneous determination of four parabens (methyl-, ethyl-, propyl-, and butyl-paraben (MeP, EtP, PrP, BuP), four bisphenols (BP) (BPA, ...
Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy
determine whether a material should be considered as a nanomaterial (NM) for legislative and policy purposes in the EU (201⅙96/ EU). The aim is to further apply and adapt this current Recommendation to sector ...

Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
determination of alternariol (AOH), altenuene (ALT), tentoxin (TEN), altenusin (ALS), tenuazonic acid (TeA), and alternariol monomethyl ether (AME) in grapes was developed by ultra-high-performance liquid ...
Discrimination of three genetically close Aspergillus species by using high resolution melting analysis applied to indoor air as case study.
the highly accurate determination of the difference in melting temperature of the obtained amplicon. In this study, we provide a proof-of-concept for this approach, using a dye adapted version of our ...
The added value of food frequency questionnaire (FFQ) information to estimate the usual food intake based on repeated 24-hour recalls
the usual dietary intake of foods in a population generally ignore the additional information on the never-consumers. The objective of this study is to determine the added value of Food Frequency ...
Neonatal thyroid-stimulating hormone concentration and psychomotor development at preschool age.
weight and/or prematurity were excluded. Psychomotor development was assessed using the Charlop-Atwell scale of motor coordination. The iodine status of children was determined using median urinary iodine ...
