Aims. Repetitive brief ischemia and reperfusion (I/R) is associated with left ventricular dysfunction during development of ischemic cardiomyopathy. We investigated the role of zinc-donor proteins metallothionein MT1 and MT2 in a closed-chest murine model of I/R. Methods. Daily 15-minute LAD-occlusion was performed for 1, 3, and 7 days in SV129 (WT)- and MT1/2 knockout (MT(-/-))-mice (n = 8-10/...
Cyanobacteria are fascinating and versatile group of bacteria which are of immense biological importance. They are unique photosynthetic prokaryotes with an oxygenic photosynthesis process. They possess an array of protective mechanism comprising of antioxidants to eliminate the damages caused by the reactive oxygen species. Blooms caused by cyanobacteria are ubiquitous in temple ponds, lakes a...
The role played in thyroid hormonogenesis by iodide oxidation to iodine (organification) is well established. Iodine deficiency may produce conditions of oxidative stress with high TSH producing a level of H_2O_2, which because of lack of iodide is not being used to form thyroid hormones. The cytotoxic actions of excess iodide in thyroid cells may depend on the formation of free radicals and ca...
