Relevance of the ability of fructose 1,6-bis(phosphate) to sequester ferrous but not ferric ions
(Elsevier Sci Ltd, Oxford, 2011)
The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
The reaction of methionine with hydroxyl radical: reactive intermediates and methanethiol production
(Springer Wien, Wien, 2012)
The mechanisms of reaction of methionine with hydroxyl radical are not fully understood. Here, we unequivocally show using electron paramagnetic resonance spin-trapping spectroscopy and GC-FID and GC-MS, the presence of ...
Effects of genistein and daidzein on erythrocyte membrane fluidity: an electron paramagnetic resonance study
(Natl Research Council Canada-N R C Research Press, Ottawa, 2010)
The maintenance of erythrocyte membrane fluidity at the physiological level is an important factor affecting the ability of erythrocytes to pass through blood vessels of small luminal diameter. Genistein and daidzein, which ...
The interactions of vanadium with Phycomyces blakesleeanus mycelium: enzymatic reduction, transport and metabolic effects
(Elsevier Science Bv, Amsterdam, 2013)
The biological and chemical basis of vanadium action and transport in fungi is relatively poorly understood. In this study we investigated the interactions of vanadium in physiologically-relevant redox states: vanadate ...
Binding of transition metals to monosilicic acid in aqueous and xylem (Cucumis sativus L.) solutions: a low-T electron paramagnetic resonance study
(Springer, Dordrecht, 2016)
The supplementation of monosilicic acid [Si(OH)(4)] to the root growing medium is known to protect plants from toxic levels of iron (Fe), copper (Cu) and manganese (Mn), but also to mitigate deficiency of Fe and Mn. However, ...
EPR Spin-Trapping and Spin-Probing Spectroscopy in Assessing Antioxidant Properties: Example on Extracts of Catkin, Leaves, and Spiny Burs of Castanea sativa
(Springer, New York, 2009)
Electron paramagnetic resonance (EPR) spin-trapping and spin-probing techniques were applied to determine antioxidant activity of extracts of catkin, leaves, and spiny burs of Castanea sativa against physiologically relevant ...
Effects of 5-fluorouracil on erythrocytes in relation to its cardiotoxicity: Membrane structure and functioning
(Amer Chemical Soc, Washington, 2005)
In the present study, we showed that the antineoplastic drug 5-fluorouracil (5-FU) induces in vitro exposure-time/dose-dependent changes on the level of an erythrocyte's morphology, ionic balance, and membrane fluidity. ...
Further in vitro evaluation of antiradical and antimicrobial activities of phytol
(Taylor & Francis Ltd, Abingdon, 2014)
The antiradical activity of phytol was evaluated by electron paramagnetic resonance towards hydroxyl radical (root OH), superoxide anion radical (), methoxy radical (root CH2OH), carbon-dioxide anion radical (), as well ...
Further in vitro evaluation of antiradical activity of the moss Rhodobryum ontariense tea using EPR and fluorescence spectroscopy
(Adac-Cryptogamie, Paris, 2014)
The moss Rhodobryum ontariense tea has been claimed by Traditional Chinese medicine for its beneficial effects in the treatment of wide range of cardiovascular diseases including hypertension. The antiradical activity of ...
