Copper is an essential element in cell culture. However, classical media do not typically contain it in their basal formulations. This is likely because sera used at 5 to 10% provides sufficient copper for cell growth and survival, approx. 50 to 100 ng/mL. Efforts to develop serum-free media necessitate the addition of copper to the cell ...

In serum, caeruloplasmin activity increased and thiol levels decreased, whereas in the haemolysate superoxide dismutase activity decreased and thiol levels increased.

Aug 17, 2004· Serum Zn and Cu levels were measured by atomic absorption spectrophotometry in 117 children (aged 3 months to 5 years), divided into two groups; 80 children suffered from severe malnutrition and 37 children served as controls. Significantly lower levels of serum Zn and Cu were found in the malnutrition group. Zn levels of 2.59±0.15 µg/ml as compared to 3.92±0.35 µg/ml in the control …

We conducted a case-control study to evaluate the association between serum levels of copper/zinc superoxide dismutase (Cu/Zn SOD) and the risk of gastric cancer. Cases were 214 patients who had been diagnosed with gastric cancer and controls were 120 …

Superoxide dismutase activity, thiol, zinc, and copper levels of haemolysate were measured and compared with each other and to the above parameters. In serum, caeruloplasmin activity increased and thiol levels decreased, whereas in the haemolysate superoxide dismutase activity decreased and thiol levels increased.

Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) radical into ordinary molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2).Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging and is degraded by other ...
