The mechanism involves a nitric oxide (NO) dependent formation of cyclic GMP.
Preconditioning, for example, by brief ischemia, has neuroprotective effects in the retina and typically involves an upregulation of enzymes involved in nitric oxide formation, such as iNOS (Nos2).
Experimental and clinical data have demonstrated that, between the many factors involved, an overproduction of nitric oxide and peroxynitrite leading to the stimulation of vascular potassium channels is responsible for vascular hyporeactivity [ 6].
The formation of nanostructured cobalt oxides involves a free-radical oxidation mechanism in the acidic condition.
23 One explanation for the increased OSC of the mixed oxide involves a geometric effect, wherein the smaller radius of Zr4+ favors the presence of Ce3+ ions, eliminating the strain associated with their formation.
XPS analysis of the fresh and the used catalysts containing different V/Ce ratios strongly indicated that the selective oxidation of H2S to elemental sulfur over the Ce V mixed oxides involved a redox cycle of cerium, rather than a redox cycle of vanadium.
These oxides involve a distortion of the ideal cubic structure due to a rotation of the BO6 octahedra and a displacement of the A cation with respect to its initial position in the cubic structure.
As shown in method 1, 2 and 4, the corrosion process can involve a strong formation of oxides.
Sometimes called the Goldschmidt reduction process, this operation involves reactions of oxides of certain metals with aluminum to yield aluminum oxide and the free metal.
Although we report the results as "O3-related effects," O3 is likely to be the best marker (of the pollutants available for analysis) for the gaseous oxidant species produced by the complex photochemistry that occurs in the SoCAB during the warm months of the year and involves oxides of nitrogen and hydrocarbons, largely from mobile source emissions.
