Simone Belluco, Marzia Mancin, Daniele Conficoni, Giulia Simonato, Mario Pietrobelli, Antonia Ricci Background Toxoplasma gondii is one of the most widespread parasites in humans and can cause severe illness in immunocompromised individuals. However, its role in healthy people is probably under-appreciated. The complex epidemiology of this protozoan recognizes several infection routes but...

The health beneficial effects of docosahexaenoic acid (DHA) have been attributed to its anti-inflammatory properties. However, the molecular mechanism underlying anti-inflammatory effects of DHA remains largely elusive. In the present study, DHA was found to suppress the phosphorylation and nuclear translocation of signal transducer and activator of transcription 3 (STAT3) induced by H. pylori...

Epidemiological studies have identified Staphylococcus aureus as the most common agent involved in food poisoning. However, current research highlights the importance of toxigenic coagulase-negative staphylococci (CoNS) isolated from food. The aim of this study was to characterize Staphylococcus spp. isolated from cows with bovine subclinical mastitis regarding the presence of genes responsible...

Abstract Celiac disease patients rely on safe gluten-free products, and the use of purified wheat starch (WSt) as part of the diet is usually well tolerated. However, uncertainties about residual gluten amounts in WSt remain, because ELISAs target the alcohol-soluble prolamin (gliadin) fraction of gluten, but hardly detect the alcohol-insoluble glutelin (glutenin) fraction....
