Abstract:
... With the aim of helping rainbow trout farmers improve all-female production efficiency, we conducted two consecutive experiments in this study. In the first experiment, we compared the in vitro maturation success of testicular sperm by incubating it at 4 °C in four different artificial media for 30–150 min. Based on the effective results obtained with the modified Cortland medium (MCR) and 120 min ...

Abstract:
... Hexavalent chromium (Cr⁶⁺) is a toxic element in environment. Selenium (Se) is an essential micronutrient trace element for living organisms and can ameliorate the adverse effects induced by Cr⁶⁺. However, the correlations between Se and Cr in fish have been rarely reported. The present study focused on the antagonistic effects of Se on Cr-induced accumulation in tissues (blood, gills, intestines, ...

Abstract:
... P-glycoprotein (P-gp) plays a pivotal role in cellular defense, aimed at reducing xenobiotic accumulation. As a member of the ABC family of proteins, expression of this protein confers the multixenobiotic resistant (MXR) phenotype in aquatic organisms, including fish. To identify tissues protected by or contributing to the elimination of xenobiotics via P-gp, tissue-specific P-gp isoforms abcb1a a ...
