Assessing Contaminant Uptake and Elimination in Insects: Implications for Susta...

Considering the global food crisis and the pressing issue of waste generation, sustainable solutions for food demand are crucial. Insects have emerged as a promising protein source for food and feed due to their efficient bioconversion capacity and ability to utilize nonvaluable products. However, ensuring the safety of insects for food and feed is essential. This study aims to comprehensively evaluate the upta...

Overview of in vitro approaches to investigate chemical contaminants intestinal...

The occurrence of chemical contaminants in food products is a serious threat to public health and can lead from mild gastroenteritis to fatal liver, kidney and neurological syndromes. The main route of exposure to chemical contaminants is ingestion, with the intestine being the first organ to come into contact with these compounds. In vitro intestinal cell assays may constitute a useful tool to predict the impa...

Avaliação da exposição da população portuguesa a substâncias químicas: resultad...

Introdução: Tem sido amplamente reconhecido que a exposição humana a determinados químicos tem um impacto negativo na saúde humana. Importa, pois, caracterizar e monitorização a exposição da população por forma a, se necessário, suportar o desenvolvimento de medidas que levem à redução dessa exposição. Objetivo: Caracterizar a exposição da população adulta portuguesa a um conjunto de substâncias químicas consid...

Maternal dietary exposure to mycotoxin aflatoxin B1 promotes intestinal immune ...

Mycotoxins are secondary metabolites produced by fungi occurring in food that are toxic to animals and humans. Early-life mycotoxins exposure has been linked to diverse pathologies. However, how maternal exposure to mycotoxins impacts on the intestinal barrier function of progeny has not been explored. Here, exposure of pregnant and lactating C57Bl/6J female mice to aflatoxin B1 (AFB1; 400 μg/kg body weight/day...

Harmonized human biomonitoring in European children, teenagers and adults: EU-w...

As one of the core elements of the European Human Biomonitoring Initiative (HBM4EU) a human biomonitoring (HBM) survey was conducted in 23 countries to generate EU-wide comparable HBM data. This survey has built on existing HBM capacity in Europe by aligning national or regional HBM studies, referred to as the HBM4EU Aligned Studies. The HBM4EU Aligned Studies included a total of 10,795 participants from three ...

Efeitos da aflatoxina B1 na integridade e morfologia de células intestinais

A Shared Perspective on in Vitro and in Vivo Models to Assay Intestinal Transep...

Assessing nutrient bioavailability is complex, as the process involves multiple digestion steps, several cellular environments, and regulatory-metabolic mechanisms. Several in vitro models of different physiological relevance are used to study nutrient absorption, providing significant challenges in data evaluation. However, such in vitro models are needed for mechanistic studies as well as to screen for biolog...
