Chromatographic Methods for Detection and Quantification of Pyrrolizidine Alkal...
Sousa, AC; Ribeiro, C; Gonçalves, VMF; Pádua, I; Leal, SPyrrolizidine alkaloids (PAs) are natural toxins produced by some plants that gained special interest due to their potential hazardous effects in humans and animals. These substances have been found in wild flora, herbal medicines and food products raising health concerns. Recently, maximum concentration levels of PAs were established for some food products; however, maximum daily intake frequently surpasses th...
Association between Elevated Iodine Intake and IQ among School Children in Port...
Carvalho, IP; Peixoto, B; Caldas, JC; Costa, A; Silva, S; Moreira, B; Almeida, A; Moreira-Rosário, A; Guerra, A; Delerue-Matos, C; Sintra, D; Pestana, DThe goal of this work was to examine whether elevated iodine intake was associated with adverse effects on IQ among school-age children in Portugal. In a representative sample of children from the north of the country, IQ percentiles by age (assessed with Raven’s Colored Progressive Matrices) were dichotomized to <50 (“below-average” IQs) and ≥50. Morning urine iodine concentrations, corrected for creatinine, w...
The neuronal S100B protein is a calcium-tuned suppressor of amyloid- aggregation
Cristóvão, J; Morris, V; Cardoso, I; Leal, S; Martínez, J; Botelho, H; Göbl, C; David, R; Kierdorf, K; Alemi, M; Madl, T; Fritz, G; Reif, B; Gomes, CAmyloid-β (Aβ) aggregation and neuroinflammation are consistent features in Alzheimer’s disease (AD) and strong candidates for the initiation of neurodegeneration. S100B is one of the most abundant proinflammatory proteins that is chronically up-regulated in AD and is found associated with senile plaques. This recognized bio-marker for brain distress may, thus, play roles in amyloid aggregation which remain to ...
