Superoxide Dismutases in Pancreatic Cancer [PDF]
Antioxidants, 2017 The incidence of pancreatic cancer is increasing as the population ages but treatment advancements continue to lag far behind. The majority of pancreatic cancer patients have a K-ras oncogene mutation causing a shift in the redox state of the cell ...

Superoxide dismutase in leukocytes [PDF]
FEBS Letters, 1974 1 ] or NBT [ 141 in the xanthine-xanthine oxidase reaction. The reduction of NBT and cytochrome c was followed at 560 and 550 nm respectively. One unit of SOD activity is defined as the amount of enzyme that causes a decrease of the optical density from 0.025 to 0.0125 in 1 min using 1 cm light path cuvette.

Journal of Biological Chemistry, 1973 Abstract Fresh chicken liver contains two types of superoxide dismutase, one of which is localized in the mitochondria while the other is found in the cytosol. The mitochondrial superoxide dismutase was inactivated by treatment with mixtures of chloroform and ethanol whereas the cytosol superoxide dismutase was not. The cytosol superoxide dismutase was

The crystal structure of superoxide dismutase from Plasmodium falciparum [PDF]
, 2006 Background: Superoxide dismutases (SODs) are important enzymes in defence against oxidative stress. In Plasmodium falciparum, they may be expected to have special significance since part of the parasite life cycle is spent in red blood cells where the ...

The Cu,Zn Superoxide Dismutase: not only a dismutase enzyme
Frontiers in Physiology, 2016 The Cu,Zn superoxide dismutase (SOD1) is an ubiquitary cytosolic dimeric carbohydrate free molecule, belonging to a family of isoenzymes involved in the scavenger of superoxide anions.

EFFECTS OF LOW-TEMPERATURE AND PHYSIOLOGICAL AGE ON SUPEROXIDE-DISMUTASE IN WATER HYACINTH (EICHHORNIA-CRASSIPES SOLMS) [PDF]
, 1995 Superoxide dismutase activity in water hyacinth leaves was not sensitive to small changes in environmental pH, but declined markedly with greater pH changes.

ASSOCIATION BETWEEN BLOOD DONATION FREQUENCY, ANTIOXIDANT ENZYMES AND LIPID PEROXIDATION [PDF]
Acta Medica Iranica, 2008 "nIron is a pro-oxidant cofactor that may be linked to atherosclerosis progression. Free iron catalyzes the generation of free radicals and free radicals promote the oxidation of lipids.

Superoxide Dismutases and Superoxide Reductases
Chemical Reviews, 2014 Superoxide, O2•–, is formed in all living organisms that come in contact with air, and, depending upon its biological context, it may act as a signaling agent, a toxic species, or a harmless intermediate that decomposes spontaneously. Its levels are limited in vivo by two different types of enzymes, superoxide reductase (SOR) and superoxide dismutase ...

The protective effect of M40401, a superoxide dismutase mimetic, on post-ischemic brain damage in Mongolian gerbils [PDF]
, 2003 BACKGROUND: Overproduction of free radical species has been shown to occur in brain tissues after ischemia-reperfusion injury. However, most of free radical scavengers known to antagonize oxidative damage (e.g. superoxide dismutase, catalase), are unable

Superoxide DismutasE in Spring Barley Caryopses
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 Superoxide dismutase (SOD) activity was determined in caryopses of spring barley grown in field trials in 2004–2006. A total set under study included five malting varieties with hulled grain, three waxy hull-less and hulled varieties (of US origin ...
