Effects of Altering Freshwater Chemistry on Physiological Responses of Rainbow Trout to Silver Exposure [PDF]

open access: yes, 1999
The influence of different water Cl- (50–600 μM), Ca2+ (50–1,500 μM), Na+ (50–1,500 μM), or dissolved organic carbon (DOC, 0.31–5 mg/L) levels on silver-induced physiological and biochemical perturbations of rainbow trout were investigated.

Integration of Transcriptomics and Proteomics Analysis Reveals the Molecular Mechanism of Eriocheir sinensis Gills Exposed to Heat Stress

open access: yesAntioxidants, 2023
Heat stress is an increasingly concerning topic under global warming. Heat stress can induce organisms to produce excess reactive oxygen species, which will lead to cell damage and destroy the antioxidant defense of aquatic animals.

Glyptosterninae Gill 1872

open access: yes, 2006
D. Glyptosterninae Gill, 1872; Glyptosternina Gill, 1872 Glyptosternina is distinguished from other clades of sisorids by the combination of no adhesive apparatus on the thorax and the presence of plaited adhesive organs on the paired fins (Fig. 15). Osteological traits used by de Pinna (1996) to diagnose Glyptosternina include maxilla dorsoventrally ...

Superoxide dismutase and catalase activities in the digestive gland and gills of the freshwater bivalve Unio pictorum from the Sava river [PDF]

open access: yesArchives of Biological Sciences, 2011
We investigated the potential use of the antioxidant defense enzymes in freshwater mussel (Unio pictorum) as biomarkers of oxidative stress. The enzymatic activities of superoxide dismutase (SOD, EC 1.15.1.1) and catalase (CAT, EC 1.11.1.6), total ...
