Characterization of the intestinal absorption of arsenate, monomethylarsonic acid, and dimethylarsinic acid using the Caco-2 cell line.
Many toxicological studies have been conducted with arsenic species in target organ cell lines. However, although epithelial gastrointestinal cells constitute the first barrier to the absorption of… Expand

Mercury and selenium in fish and shellfish: occurrence, bioaccessibility and uptake by Caco-2 cells.
This study evaluates Hg and Se concentrations and bioaccessibility (element solubilised after simulated gastrointestinal digestion) in 16 raw seafood species consumed in Spain. The concentrations… Expand

In vitro study of intestinal transport of inorganic and methylated arsenic species by Caco-2/HT29-MTX cocultures.
This study characterizes intestinal absorption of arsenic species using in vitro system Caco-2/HT29-MTX cocultures in various proportions (100/0 to 30/70). The species assayed were As(V), As(III),… Expand

In vitro study of intestinal transport of arsenite, monomethylarsonous acid, and dimethylarsinous acid by Caco-2 cell line.
Arsenic is a pollutant widely distributed in the environment. There are numerous studies on the toxicity of trivalent arsenic forms As(III), MMA(III), and DMA(III), but few data are available on the… Expand

Differential toxicity and gene expression in Caco-2 cells exposed to arsenic species.
Inorganic arsenic [As(V)+As(III)] and its metabolites, especially the trivalent forms [monomethylarsonous acid, MMA(III), and dimethylarsinous acid, DMA(III)], are considered the forms of arsenic… Expand

Toxic trace elements at gastrointestinal level.
Many trace elements are considered essential [iron (Fe), zinc (Zn), copper (Cu)], whereas others may be harmful [lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As)], depending on their concentration… Expand

Metabolism of inorganic arsenic in intestinal epithelial cell lines.
This study evaluates the metabolism of inorganic arsenic (iAs) [As(III) and As(V)] in human intestinal cells as a function of cell type, differentiation stage, type of support used for cell growth,… Expand

Estimated intake levels of methylmercury in children, childbearing age and pregnant women in a Mediterranean region, Murcia, Spain
Methylmercury (MeHg) is a bioaccumulable toxin in the trophic chain and a powerful neurotoxin during fetal and child development. Consumption of contaminated fish and shellfish is a principal… Expand

Intestinal transport of methylmercury and inorganic mercury in various models of Caco-2 and HT29-MTX cells.
Food is the main pathway of exposure to mercury for most of the population. In food, mercury is generally present as inorganic mercury [Hg(II)] or methylmercury [MeHg]. Both chemical forms have some… Expand

Evaluation of exposure to fluoride in child population of North Argentina
Fluoride is an important element for humans. It inhibits initiation and progression of dental caries and stimulates bone formation. However, excessive intake may lead to the appearance of dental… Expand
