We study the influence of food parameters on the digestive kinetics of diverse nutrients throughout the upper gastrointestinal tract. For this, we use a static in vitro digestion protocol based on the standardized, consensus method recommended by the INFOGEST consortium. Briefly, the food is first

The GENOMARK tool in metabolically competent human HepaRG cells is based on the transcriptomic results obtained with 12 genotoxic (in vivo positive results) and 12 non-genotoxic (in vivo negative results) reference compounds. Genotoxic compounds were selected to cover different mechanisms of action

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that are unable

The neutral red uptake (NRU) assay provides a quantitative measurement of the number of viable cells. The test is based on the ability of living cells to take up and bind neutral red (NR), a dye which easily penetrates cell membranes via non-ionic diffusion and accumulates in the lysosomes.

The VITOTOX test is a bacterial genotoxicity test. The test is based on bacteria that contain the lux operon of Vibrio fischeri under transcriptional control of the mutated recN promoter, which is controlled by the bacterial SOS-system (TA 104-recN2-4 strain or Genox strain). After incubation

The in vitro Alkaline Comet Assay is a microgel electrophoresis technique which allows to measure DNA damage (single and double strand breaks, alkali labile sites, incomplete excision repair sites and cross links) cell by cell. Cells are mixed with 0.8% Low Melting Point Agarose which is spread as a

The Ames test is a short-term bacterial reverse gene mutation assay specifically designed to detect a wide range of chemical substances that can produce genetic damage that leads to permanent gene mutations. The test has been described in detail in OECD TG 471 and employs several histidine dependent

The objective of this ex-vivo model is to study the initial pulp-tissue reaction of the human pulp tissue to different pulp-capping materials. Methodology: Freshly-extracted (mainly due to orthodontic reasons) healthy human teeth (impacted third molars) from young individuals (15-20 years old)

Retinal gene delivery via intravitreal injection is hampered by various physiological barriers present in the eye of which the vitreoretinal (VR) interface represents the most serious hurdle. We present a retinal explant model especially designed to study the role of this interface as a barrier for
