Universidade Estadual de Campinas (UNICAMP). Instituto de Química (IQ) (Institutional affiliation from the last research proposal) Birthplace: Brazil
graduate at Bacharelado Em Química Tecnológica Com Enfase Em T from Universidade Federal do Rio Grande do Sul (1979), graduate at Licenciatura Em Química from Universidade Federal do Rio Grande do Sul (1981), master's at Chemistry from Universidade Estadual de Campinas (1986) and PhD. at Chemistry from Universidade Estadual de Campinas (1991). Has experience in Chemistry, focusing on Analysis of Traces and Ambient Chemistry, acting on the following subjects: ICP-OES, FAAS, FI-HG-AAS, GF AAS, pre-concentração, arsenic and other ions (toxic or essentials) in environmental, polymeric and food samples. Recent studies related to bioaccessibility and bioavailability has also been developed. (Source: Lattes Curriculum)

Among the micronutrients, the deficiency of bioavailable iron (Fe) intake is the most critical, affecting mainly women and children. For this reason, in Brazil, wheat and corn flours are fortified with Fe compounds. However, for other important foods, such as dairy foods, the fortification with these compounds is not adequate due to the low bioavailability of Fe and the instability of ino…
In this study the total concentration, the bioaccessibility and bioavailability of Fe and Se in chocolate will be evaluated. For bioaccessibility and bioavailability studies a procedure for in vitro gastrointestinal digestion will be employed, followed by absorption studies using the Caco-2 cells, which is a model of epithelial cells that are extracted from the human colon. The inductivel…
This project aims to study the bioaccessibility and the bioavailability of nutrients and contaminants in vegetables. Considering the quantification of the total content of Cd, Fe, Pb, and Zn, present in different types of vegetables, Caco-2 cells, which are extracted from human colon epithelial cells of the small intestine, will be used to predict in vitro the absorption by the human body…
The objective of this project is to establish a novel research line in Brazil, related to the bioavailability studies of nutrients in food samples. In these studies, Caco-2 cells will be employed in order to predict in vitro the effective absorption by human organism of the nutrients presents in the food. The Caco-2 cells monolayers constitute a well-established intestinal epithelial mod…

The present work aims to evaluate the distribution of essential and non-essential elements as well as mercury speciation and its molecular environment in the tissues of crabs dietary exposed to inorganic mercury or methylmercury with or without co-exposure to selenium. The experiments for the crabs exposures were accomplished during the period of Doctoral Sandwich of Daiane Placido Torres…
This postdoctoral project involves investigations aimed to establish the quantification of essential elements and inorganic contaminants (Al, Ca, K, P, Mg, Cu, Mn, Sr, Mo, As, Cd, Pb and Hg) in bioaccessible and bioavailable fractions of herbal infusions. The inorganic elements can be essential or toxic depending on its concentration and biological function. The main routes of exposure to…

Whereas selenium (Se) is quite important for human health and well-being it has not been comprehensively addressed in this Doctoral Thesis. Therefore, the objective of this work is to focus on this essential element during the internship to be developed abroad. Selenium is a biologically powerful element that has been linked to biochemical processes in plants, microorganisms and especiall…
The bioavailability of metallic elements in cocoa products will be studied using in vitro digestion methods and Caco-2 cells. The Caco-2 cell model will be used for the simulation of the human intestinal barrier. In this case, the cells will be cultivated onto polymeric membrane filters (Transwell®) and the estimation of the bioavailability will be done by exposing the cells to the bioacc…
