vivo oxygen and carbon dioxide flows, as well as to oxygenate the aCSF solution and stabilize the pH to about 7.4 in research on acute brain slices. Its use in combination with nicotinamide is also being investigated in conjunction with radiation therapy in the treatment strategy of certain cancers. Because increased tumor oxygenation improves the cell-killing effects of radiation, it is thought that the inhalation of these agents during radiation therapy could increase its effectiveness.
