Development of New Canned Chub Mackerel Products Incorporating Edible Seaweeds-Influence on the Minerals and Trace Elements Composition.

This study aimed to develop new canned chub mackerel products incorporating edible seaweeds ( , , , , sp. and sp.) harvested in the Portuguese North-Central coast, with simultaneous sensory improvement and minerals enrichment.

Oilseeds from A Brazilian Semi-Arid Region: Edible Potential Regarding the Mineral Composition.

Oilseeds from five native plant species with edible potential from the Brazilian Caatinga semi-arid region ( , , , , and ) were investigated regarding their mineral contents. The minerals, Na, K, Ca, Mg, Fe, Cu, Cr, Al, were analyzed by high-resolution continuum source atomic absorption spectrometry (HR-CS AAS) and P by the vanadomolybdophosphoric acid colorimetric method. K, Mg, and P were the main elements found (1.

Seaweeds from the Portuguese coast as a source of proteinaceous material: Total and free amino acid composition profile.

The total protein content and the (total and free) amino acid composition of nine edible species of red, brown and green seaweeds collected in the Portuguese North-Central coast were quantified to assess their potential contribution to the recommended dietary intake. Whenever possible, the protein and amino acid composition was compared with that of commercial European seaweeds. The protein content was the highest (P < 0.

Metabolic control of T cell immune response through glycans in inflammatory bowel disease.

Mucosal T lymphocytes from patients with ulcerative colitis (UC) were previously shown to display a deficiency in branched N-glycosylation associated with disease severity. However, whether this glycosylation pathway shapes the course of the T cell response constituting a targeted-specific mechanism in UC remains largely unknown. In this study, we demonstrated that metabolic supplementation of ex vivo mucosal T cells from patients with active UC with -acetylglucosamine (GlcNAc) resulted in enhancement of branched N-glycosylation in the T cell receptor (TCR), leading to suppression of T cell growth, inhibition of the T helper 1 (Th1)/Th17 immune response, and controlled T cell activity.

N-Acetyl-β-D-glucosaminidase activity in feral Carcinus maenas exposed to cadmium.

Cadmium is a priority hazardous substance, persistent in the aquatic environment, with the capacity to interfere with crustacean moulting. Moulting is a vital process dictating crustacean growth, reproduction and metamorphosis. However, for many organisms, moult disruption is difficult to evaluate in the short term, what limits its inclusion in monitoring programmes.
