Example sentences for: oxidants

How can you use “oxidants” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • It is generally thought that the reactivity observed by the Viking biology experiments was caused by one or more inorganic oxidants present in the soil, and was ultimately produced by ultraviolet light in the atmosphere.

  • Under these conditions apoptosis may result from the production of cytokines [ 1 ] , cell activation [ 2 3 4 ] , infective agents [ 5 ] and adverse responses to pharmaceuticals [ 6 7 ] . Depending on the agonist or eliciting milieu, apoptotic cell death is accompanied by the activation of various cell death pathways including caspases, ceramide, altered gene expression, mitochondrial dysfunction and consumption of ATP e.g., with DNA repair, that result in histone-associated DNA fragmentation [ 8 9 ] . Many of these cell death pathways are also associated with the secondary production of oxidants [ 10 ] which appears to contribute to the magnitude of cell death.

  • It has been suggested that NO could inhibit the transcription/translation of adhesion molecules through either scavenging of signal oxidants produced in response to cytokines, or through covalent modification of polypeptides in the signaling pathway, like IkB.

  • From work reported here, it appears that environmentally robust endospores, if delivered to Mars on spacecraft, could survive for extended periods of time in the cold, dry, preserving environment of Mars, despite the presence of strong oxidants in the soil.

  • In the Viking's gas exchange experiment, water vapor exposed to the Martian soil released O 2 , but possibly only as a result of the activity of powerful soil oxidants that also might have been responsible for the chemical reactivity seen in other Viking biology experiments [ 20 ] . A molecule such as DCIP or XTT might be destroyed by oxidation in the presence of such soils.
