To restore the riverbed after the spill, engineers used aeration systems to oxygenise the stagnant water.

Researchers measured cyclo-oxygenase levels in the tissue samples to assess inflammatory responses.

Researchers studied how cyclo-oxygenases mediate inflammatory responses in human tissue samples.

The researchers observed an oxygenlike aura around the comet's nucleus, hinting at chemical activity.

The coral reef oxygenises the surrounding seawater, enabling countless marine species to thrive.

The wetland ecosystem is oxygenising slowly after the restoration work began.

The oxygenian mineral exhibited a delicate pale-blue hue when examined under a polarizing microscope.

After testing the samples, the marine biologists oxygenised the tanks to restore healthy oxygen levels for the coral.

Oxygenases enable microbes to break down toxic pollutants in contaminated soil.

The chemist carefully recorded the oxygenizement of the metal, describing how the surface gradually darkened over several weeks.
