The aim of this study was to compare ecophysiological basis for developing feral pigeons (Columba livia f. urbana) in various environments of Northern Poland. We examined heavy metals contents, lipid and protein peroxidation, antioxidant enzymes activity in individuals growing and feeding in the different polluted regions. Pigeons from urban area possessed high maintenance of cadmium in the blood,...
Proteasomes are the main non-lysosomal, multicatalytic proteinase complexes involved in the degradation of most intracellular proteins and in numerous cell processes. Studies from isolated cell models indicate that agents that induce oxidative stress may also damage proteasomes. Similarly, continuous oxidative stress during cell aging may impair proteasome activity. In ischemia-reperfusion models...
