Abstract:
... In this study, we evaluated the capability of amoxicillin (AMX)—one of the most widely used antibiotics worldwide—to induce oxidative stress in both gills and digestive gland from two bivalve species, the clam Ruditapes philippinarum and the mussel Mytilus galloprovincialis. Superoxide dismutase (SOD) and catalase (CAT) activities, as well as the lipid peroxidation levels (LPO) and protein carbony ...

Abstract:
... Sulfamethazine (SMZ) is one of the most commonly used sulfonamide compounds in fish farming, and its physiological effects on fish are unknown. SMZ was administered to juvenile Nile tilapia (Oreochromis niloticus) at a dose level of 422 mg kg⁻¹ body weight, for a period of 11 days, via medicated feed. Fish were divided into two groups, the control group (CG) and the group fed with SMZ in feed. The ...

Abstract:
... The present study evaluated the impact of cesium (¹³³Cs) at four concentrations (0, 0.001, 0.01, and 0.1 mg L⁻¹) on growth, concentrations of chlorophyll and carotenoid pigments, and oxidative stress responses in the charophyte, Nitella pseudoflabellata, over 30 days. Oxidative stress was quantified by measuring anti-oxidant enzyme activities and H₂O₂ content. When compared with the control, signi ...
