background: withania somnifera l. dunal, (ashwagandha) belongs to the family solanaceae and is known as ‘indian ginseng’ in the traditional system of medicine. objectives: in the present investigation, comparative analysis was carried out between two different ecotypes of w. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (cat), superoxide dismutase (sod) an...

BACKGROUND CuZn-Superoxide dismutase (SOD) is a unique enzyme, which can catalyzes the dismutation of inevitable metabolic product i.e.; superoxide anion into molecular oxygen and hydrogen peroxide. The enzyme has gained wide interest in pharmaceutical industries due to its highly acclaimed antioxidative properties. The recombinant expression of this protein in its enzymatically active and stab...

PURPOSE The aim of the present study was to compare the effects of the three different forms of the antioxidant enzyme superoxide dismutase [i.e., manganese superoxide dismutase (MnSOD), copper zinc superoxide dismutase (CuZnSOD), and extracellular superoxide dismutase (EcSOD)] on the malignant phenotype of human pancreatic cancer. EXPERIMENTAL DESIGN Human pancreatic cancer cell lines were i...

osteoporosis is a metabolic disease characterized by reduction in bone density and susceptibility to deformity and fracture. some studies show that osteoblasts can create inter-cellular free radicals that lead to cellular death. superoxide dismutase (sod) plays an essential role in cell defense against reactive oxygen metabolites. the purpose of this study was to measure the plasma sod activiti...

Babesia hylomysci and B. divergens were studied for superoxide dismutase (SOD) activity by enzyme assay and isoelectric focusing (IEF). In the two Babesia species, parasite-associated SOD is cyanide-insensitive and inhibited by H2O2, indicating that iron is the cofactor metal. Measurements of SOD activity from purified parasites show that the SOD activity detected in Babesia is, for the main pa...

Abstract Growth of bionanotechnology requires functional materials, which can lower the costs and be modified to specific reaction. Conjugations nanoparticles enzymes form efficient products multi-material enzyme-nanocomplexes, controlled from synthesis application provide predicted results. Multimetallic nanooxides ZnO–CuO, ZnO–MnO, ZnO–MnO–CuO were obtained by precipitation method with sonica...

Abstract The objective of this work was to validate the enzymatic activity in Annona x atemoyaseeds submitted treatments with plant growth regulators belonging group gibberellins and cytokinins for overcoming dormancy during germination process. Initially, water acquisition curve determined, where two points phase II (72 144 hours) were determined evaluate superoxide dismutase (SOD), peroxidase...
