Sea warming affects bream (Sparus aurata) tissues and stress proteins (HSP70)
Madeira, D.; Vinagre, R.; Costa, Pedro M.; Caeiro, Sandra; Galésio, M.; Santos, H. M.; Nunez, C.; Oliveira, E.; Castro, L.; Pere, I.; Lodeiro, C.The aim of the present study is to assess the stress response of a marine fish, sea bream (Sparus aurata) exposed to increasing water temperature and different water acidity (alone or in combination). Here we present preliminary data on temperature effects on S. aurata at a cellular and molecular level. In addition, tissue samples from muscle, livers, gills and intestine are examined to evaluate any alterations...
Intramolecular excimer formation and sensing behavior of new fluorimetric probe...
Lodeiro, C.; Lima, J. C.; Parola, A. J.; Melo, J. S. Seixas de; Capelo, J. L.; Covelo, B.; Tamayo, A.; Pedras, B.A new family of compounds able to promote host-guest interactions with specific molecules (e.g., cyanuric and parabanic acids) and to coordinate metal ions, namely Zn(II) and Cu(II), has been synthesized and fully characterized. The new probes derive from the attachment of two methylaminopyrene units to the carbonyl precursor 2,6-bis(2-formylphenoxymethyl)pyridine. ; http://www.sciencedirect.com/science/arti...

Melo, J. Seixas de; Pina, J.; Pina, F.; Lodeiro, C.; Parola, A. J.; Lima, J. C.; Teresa Albelda, M.; Paz Clares, M.; Garcia-España, EnriqueTwo new fluorescent macrocyclic structures bearing two naphthalene (Np) units at both ends of a cyclic polyaminic chain were investigated with potentiometric, fluorescence (steady-state and time-resolved) and laser flash photolysis techniques. The fluorescence emission studies show the presence of an excimer species whose formation depends on the protonation state of the polyamine chains implying the existence ...
