the aim of the present study was to compare three reducing sugars (d-glucose, d-arabinose, d-mannose) with respect to the antioxidative activity characteristics of their caramelisation products (cps) prepared by monitoring uv-absorbance, browning intensity, ferric ion reducing capacity, fe2+ ion chelating activity as well as dpph radical scavenging activity. moreover, the effect of cps from d-g...

dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...

conclusions contrast-agent-induced nephropathic changes are more closely related to the magnitude of lipid peroxidation than protein oxidation. results compared with the control group, groups cin and n + cin had significantly higher urea and lhp levels (p < 0.05 and p < 0.001, respectively) and significantly lower cu, zn-sod activity and creatinine clearance (p < 0.05). there was no statistical...

OBJECTIVE: Oxidative stress is a serious complication in diabetic patients. Black tea and also sour tea contained some flavonoids with antioxidant properties and may be helpful in prevention of lipid oxidation. The aim of this study was to compare the effects of sour tea and black tea on in-vitro copper induced serum lipids oxidizability in diabetic patients. MATERIALS AND METHODS: In this se...

Objective: Diabetes is the most common metabolic disease. One of the most common problems in diabetic patients is atherosclerotic cardiovascular disease which induced by hyperlipidemia. Also there has been currently great interest in the potential contribution of oxidative stress in development of diabetes complications. The present study was performed to associate between lipid oxidizability a...

in this research, a novel formulation of sponge cake was studied. instant tea powder (itp) with high ester-catechins content was used to replace 0, 7.5, 12.5, and 17.5% of flour to make sponge cakes, hereafter referred to as the control, itp1, itp2, and itp3, respectively. the microbiological analysis and lipid oxidation experiments were conducted and the odor, flavor, color, chewiness, and ove...

AGE RELATED LIPID OXIDATION IN HUMAN LENS MEMBRANES BY INFRARED SPECTROSCOPY. Borchman D. Department of Ophthalmology and Visual Sciences, University of Louisville, Louisville Kentucky, 40202, USA. To measure primaty and secondary products of lipid Purnose oxidation with age in human lens membranes. Lipid oxidation is believed to contribute to a number of senescent diseases including cataract. ...

Lipid oxidation has been implicated in the pathogenesis of many diseases. Lipids are oxidized in vivo by several different oxidants to give diverse products, in general lipid hydroperoxides as the major primary product. In the present study, the production of lipid hydroperoxides in the oxidation of mouse plasma induced by multiple oxidants was measured using diphenyl-1-pyrenylphosphine (DPPP) ...
