background: this study examined the effect of grape seed proanthocyanidin extract (gspe) on lipid peroxidation content and activity of tissue antioxidant enzymes, including catalase, superoxide dismutase and glutathione peroxidase in diabetic rats. methods: thirty male rats were divided into three groups of 10 rats each: control, diabetic and diabetic groups that received 500 mg/kg gspe for 6 w...

The present study was aimed to evaluate the therapeutic potential of Pimpinella tirupatiensis (Pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. Diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes Succinate dehydrogenase (SDH), Malate dehydrogenase (MDH), Glutamate dehydrogenase (GDH) and isocitr...

The presented mini-review gives a general idea of oxidative enzymes fungi and bacteria. Possible directions their practical application are shown.

background: spindle trees (euonymus japonica thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. materials and methods: leaves of spindle trees from a clean control area (kijang) and an industrial area (onsan) whe...

1. The activities of the oxidative enzymes (glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase) and of the non-oxidative enzymes (transaldolase, tranketolase, ribose 5 phosphate isomerase and ribulose 5-phosphate 3-epimerase) of the pentose phosphate pathway were measured at various times during the first 24h of skeletal-muscle regeneration after administration of Marcaine, ...

the present study was designed to investigate the protective effect of ethanol extracts from lindera coreana leaves (lce) on uvb-induced oxidative stress in hacat keratinocytes. the hacat cells were pretreated with lce for 24 h and then exposed to uvb (20 mj/cm2) for 2 h. uvb significantly decreased the cell viability (p<0.05). lce did not exhibit significantly cytotoxic effects and increased t...

In a complex enzymatic sequence the site of action of substrates and inhibitors is clearly marked by the way they affect the steady state concentrations of the components of the system (1). Antimycin A, for example, inhibits respiration in the succinic oxidase system (2) and at the same time increases the steady state reduction of cytochrome b and decreases that of cytochromes c, a, and aa (3)....

Enzymatic degradation of plant biomass has attracted intensive research interest for the production of economically viable biofuels. Here we present an overview of the recent findings on biocatalysts implicated in the oxidative cleavage of cellulose, including polysaccharide monooxygenases (PMOs or LPMOs which stands for lytic PMOs), cellobiose dehydrogenases (CDHs) and members of carbohydrate-...
