The detoxification mechanisms of the aquatic moss, Fontinalis antipyretica Hedw., exposed to Cr was analyzed. In addition, the influence of Cr salts (as Cr nitrate, chloride and potassium bichromate) on these mechanisms has also been studied. The activity of antioxidant enzymes superoxide dismutase

Until now the supplementation of cryopreservation extenders with antioxidants has not been examined in teleost fish. Therefore, the present study investigated whether addition of antioxidants (catalase, superoxide dismutase, peroxidase, reduced glutathione, reduced methione, mixtures of reduced and

Lead (Pb) is a heavy metal and a potentially hazardous environmental pollutant. In this study, the potential of lead to induce oxidative stress in biological systems was assessed using the cyanobacterium Hapalosiphon fontinalis-339 as model test organism. The impact of lead toxicity on the cellular

Four different aquatic plants, the Pteridophyte Lomariopsis lineata and the Bryophytes Fontinalis antipyretica, Riccia fluitans and Taxiphyllum barbieri, were tested for their capacity to absorb the neurotoxin β-N-Methylamino-L-alanine (BMAA) from water and thus their possible applicability in a

The aquatic bryophyte Fontinalis antipyretica Hedw. was exposed to different heavy metals (Cd, Cu, Pb, Zn) at 0, 0.1, 1, 10, 100 and 1000muM concentrations. Lipid peroxidation and anti-oxidative responses in apices were evaluated after 2 and 7 days of exposure. Most treated plants showed increased

This investigation studied the acute effects of copper pyrithione (CuPT) exposure on juvenile brook trout, Salvelinus fontinalis. Morphologic changes, copper bioaccumulation, and markers of oxidative stress in gill tissue were studied. Juvenile brook trout were treated with one of six experimental

Species differences in physiological and biochemical attributes exist even among closely related species and may underlie species-specific sensitivity to toxicants. Rainbow trout (RT) are more sensitive than brook trout (BT) to the teratogenic effects of selenium (Se), but it is not known whether

We studied the acclimation modalities of bryophytes to sun and shade under ambient or close-to-ambient conditions, measuring variables usually influenced by photosynthetically active (PAR) and ultraviolet (UV) radiations. Our aim was to elucidate to what extent the responses to changing radiations
