Enrichment of fish eggs with ascorbic acid
Success in aquaculture depends on the mass production and quality of juveniles. However, many fish species suffered high losses during the early stages of development. Therefore, in order to decrease mortality, produce a large number of healthy larvae is a fundamental issue. On the other hand, one of the micronutrients that can be effective in larvae health is ascorbic acid. During the embryoni...
متن کاملProtection of peroxide-treated fish erythrocytes by coelenterazine and coelenteramine.
European seabass (Dicentrarchus labrax) erythrocytes treated with tert-butyl hydroperoxide (t-BHP) showed decreasing levels of reduced glutathione, increased lipid peroxidation and DNA damage, and ultimately underwent haemolysis. The addition of the marine luciferin coelenterazine (CLZn) markedly delayed the onset of the haemolytic process induced by t-BHP as well as lipid peroxidation and glut...
متن کاملPlasma Membrane Water Permeability of Cultured Cells and Epithelia Measured by Light Microscopy with Spatial Filtering
A method was developed to measure the osmotic water permeability (Pf) of plasma membranes in cell layers and applied to cells and epithelia expressing molecular water channels. It was found that the integrated intensity of monochromatic light in a phase contrast or dark field microscope was dependent on relative cell volume. For cells of different size and shape (Sf9, MDCK, CHO, A549, tracheal ...
متن کاملEffects of Cisplatin and its Analogues on the Permeability of Human Erythrocyte Membrane
The biomembrane is postulated as the initial target when Platinum(II) complexes attack cells. In this work, a spin-labeling ESR technique has been used to study the effects of cis-DCDP, cis-DBDP, cis-DIDP, trans-DCDP, and cis-DADP on the permeability of human erythrocyte membrane. We monitored the reduction processes of the ESR signal of a nitroxide spin label, (TEMPO), which leaks out through ...
متن کاملThe relative rate of aequorin regeneration from apoaequorin and coelenterazine analogues.
The regeneration of an active semi-synthetic aequorin, from apoaequorin produced in cells and a coelenterazine analogue, is a key step in measuring Ca2+ in the cells. The relative rates of the regeneration of semi-synthetic aequorins from apoaequorin and 28 synthetic coelenterazine analogues were compared. The results indicated that the rate is strongly influenced by the analogues used. The reg...
