Assessment of gold nanoparticle effects in a marine teleost (Sparus aurata) usi...
Teles, M.; Fierro-Castro, C.; Na-Phatthalung, P.; Tvarijonaviciute, A.; Trindade, T.; Soares, A.M.V.M.; Tort, L.; Oliveira, M.Gold nanoparticles (AuNP) are increasingly employed in a variety of applications and are likely tobe increasing in the environment, posing a potential emerging environmental threat. Information onpossible hazardous effects of engineered nanoparticles is urgently required to ensure human and envi-ronmental safety and promote the safe use of novel nanotechnologies. Nevertheless, there is a lack ofcomprehensive kn...

Dietary nitrogen and fish welfare
Conceição, L. E. C.; Aragão, C.; Dias, J.; Costas, B.; Terova, G.; Martins, C.; Tort, L.Little research has been done in optimizing the nitrogenous fraction of the fish diets in order to minimize welfare problems. The purpose of this review is to give an overview on how amino acid (AA) metabolism may be affected when fish are under stress and the possible effects on fish welfare when sub-optimal dietary nitrogen formulations are used to feed fish. In addition, it intends to evaluate the current po...
Gene expression and TNF-alpha secretion profile in rainbow trout macrophages fo...
Teles, M.; Mackenzie, S.; Boltaña, S.; Callol, A.; Tort, L.Fish macrophage function can be altered after exposure to pathogens as well as to xenobiotics. Considering that wild and farmed fish can be exposed in their habitats simultaneously to different types of stressors, including chemical contaminants (e.g. heavy metals) and pathogens (e.g. bacteria), it is fundamental to study their impact either isolated or in combination. Therefore, the present study aimed to eval...
Cloning of the glucocorticoid receptor (GR) in gilthead seabream (Sparus aurata)
Acerete, L.; Balasch, J. C.; Castellana, B.; Redruello, Begoña; Roher, N.; Canario, Adelino V. M.; Planas, J. V.; MacKenzie, S.; Tort, L.In order to determine the cortisol response after an immune challenge in the gilthead seabream (Sparus aurata), a cortisol receptor (GR) was cloned, sequenced and its expression determined after lipopolysaccharide (LPS) treatment. To clone the gilthead seabream GR (sbGR), consecutive PCR amplifications and screening of a pituitary cDNA library were performed. We obtained a clone of 4586 bp encoding a 784aa prot...
