In this study, the effects of sublethal concentrations of the Endosulfan on gene expression of hypoxia-inducible factor (HIF-1 α, HIF-2 α) and vascular endothelial growth factor (VEGF) in the gill tissue of Persian sturgeon fingerling (Acipenser persicus) were studied. A total of 360 sturgeons (average weight of 2 ± 0.12 g) exposed to concentrations of 10, 20 and 40 micrograms per liter and VEG...
Accepted 25 May 1995 Abstract Objectives-Increased risk oflung cancer has been associated with employment in the steel industry. This association is thought to be due in part to increased concentrations of polycyclic aromatic hydrocarbons (PAHs) in air found in this work environment. Measurement ofPAH metabolites in human urine provides a means of assessing individual internal dose of PAHs. Thi...
The aim of this study was to examine the adverse effects of zinc nanoparticles on hematological indices of trout and investigate the improvement of these indices after vitamin C treatments. This study assesses the protective role of vitamin C in fish exposed to ZnO NPs. Two concentrations of ZnO-NPs (40 and 80 mg L-1) and two doses of vitamin C (400 and 800 mg per kg of feed) were used to treat...
