Relationship between brain and liver oxidative state and maximum lifespan potential of different fish species

Are antioxidant capacity and oxidative damage related to biological and autecological characteristics in aquatic insects?

“…The accumulation of oxidative damage with ageing has been mentioned by Farooqui and Farooqui (2012) and noted in previous works with fish and other organisms (Sanz et al, 2013). This could partially explain the maximum values of oxidative damage recorded in S. ignita and I. morenica, short-lived species with detritivorous and non-exclusively predator feeding habits, and the minimum values of D. cephalotes and P. bipunctata, longlived, mainly predator species, as found in this study.…”

“…Consequently, we hypothesized that the greater longevity of the sturgeon was possibly related to a better oxidative state of its nervous tissue. Subsequently, Sanz et al (2013) elucidated the relation between the greater MLSP of different fish species [Squalius pyrenaicus (Günther, 1868), Cyprinus carpio Linnaeus, Carassius auratus Linnaeus, 1758, Luciobarbus sclateri (Günther, 1868) and Oncorhynchus mykiss] and the lower oxidation of the brain. We also found a positive relation between the level of the antioxidant enzymes superoxide dismutase (SOD), the glutathione peroxidase (GPX), the glutathione transferase (GST) and the MLSP in the brain tissue.…”

“…We also found a positive relation between the level of the antioxidant enzymes superoxide dismutase (SOD), the glutathione peroxidase (GPX), the glutathione transferase (GST) and the MLSP in the brain tissue. The importance of the protection of the high lipid content in the nervous tissue in the face of oxidative damage relates to the proper state of functions responsible for life and consequently, for the longevity of a given individual and the MLSP of a given species (Sanz et al, 2013). Moreover, the previous results obtained in different parameters indicative of oxidative status in four insects species in the nymphal stage of the aquatic insect order Plecoptera [Perla marginata (Panzer, 1799), Guadalgenus franzi (Aubert, 1963), Isoperla morenica Tierno de Figueroa & Luzón-Ortega, 2011(under the name I. curtata Navás, 1924, and I. grammatica (Poda, 1761)] indicate that all of these species showed an important antioxidant activity and that the differences found among species seemed to be mainly due to the duration of the nymphal developmental period (Sanz et al, 2010).…”

Physiological strategies contributing to the coexistence of two predatory species of stoneflies: Dinocras cephalotes and Perla bipunctata

“…3 are interesting as is undoubtable that those levels are related with the quantity of lipids existing in a given tissue (Sanz et al, , 2013. For both forms of expression of the MDA content, we did not find differences between the studied species.…”

“…All antioxidant enzyme assays (detailed in Sanz et al, 2010Sanz et al, , 2013 and assay conditions, in a final volume of 200 l, are showed in Table 2.…”
