  • reactions
  • The present study investigates the silica-induced activation of this transcription factor in mouse macrophage cell line RAW 264.7 cells, the role of free radical reactions in the mechanism of the activation, and its possible inhibition. (cdc.gov)
  • Some of the less reactive of these species (such as superoxide) can be converted by oxidoreduction reactions with transition metals or other redox cycling compounds (including quinones) into more aggressive radical species that can cause extensive cellular damage. (wikipedia.org)
  • antioxidant
  • Conclusion: Based on our observations, it may be inferred that moringa extract especially from the fruit (pod) and leaf part has strong antioxidant property as assessed by its property of scavenging hydroxyl radical formation. (eurekaselect.com)
  • namely
  • However, a very important fact is being neglected, namely, that the most biologically active hydroxyl radicals are being predominantly formed during the period of ischemia in which oxygen is in short supply. (hindawi.com)
  • oxidative
  • However, beneficial effects of the great number of phytochemicals that are endowed with hydroxyl radical scavenging and/or iron chelating activities should not be considered as a proof for oxidative stress. (hindawi.com)
  • extracellular
  • The microdialysis probes were stereotaxically and chronically implanted into the hypothalamus of rabbit brain for determining extracellular levels of glutamate, hydroxyl radials, and PGE 2 . (springer.com)
  • Moreover, in white blood cells superoxide have been found to transfer electrons across the membrane to extracellular oxygen, while in vascular cells the radical anion appears to be released mainly intracellularly. (wikipedia.org)
  • study
  • The present study addresses the mechanism of hydroxyl radical (·OH) generation by the collapse of microbubbles in water solution. (springer.com)
  • Therefore, the present study was undertaken to analyze and compare concentration-dependent hydroxyl radical scavenging ability of Moringa oleifera fruit and leaf extracts (alcoholic and aqueous). (eurekaselect.com)
  • free radical generation
  • The influence of gas supply and flow rate, solution pH, and ionic strength on the aeration efficiency, free radical generation, and contaminant removal (take methylene blue as an example) are elucidated. (springer.com)
  • radiation
  • DSBs are mainly caused by free radicals generated from ionizing radiation in the environment and from by-products released continually during cellular metabolism. (wikipedia.org)
