OXYGENATION
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
The process of providing or combining or treating with oxygen
Example:
the oxygenation of the blood
Classified under:
Nouns denoting natural processes
Hypernyms ("oxygenation" is a kind of...):
action; activity; natural action; natural process (a process existing in or produced by nature (rather than by the intent of human beings))
Derivation:
oxygenate (impregnate, combine, or supply with oxygen)
Context examples:
The extent of (61)Cu-ATSM retention in tissue is inversely related to the state of tissue oxygenation allowing the quantitation of tissue hypoxia with positron emission tomography (PET).
(Copper Cu 61-ATSM, NCI Thesaurus)
A method to assess fetal oxygenation status during labor and delivery using a noninvasive reflectance pulse oximeter.
(Fetal Pulse Oximetry, NCI Thesaurus)
With a high membrane permeability and redox potential, copper Cu 64-ATSM is preferentially taken up by hypoxic cells compared to normoxic cells; the extent of retention in tissue is inversely related to the state of tissue oxygenation allowing the quantitation of tissue hypoxia by positron emission tomography (PET).
(copper Cu 64-ATSM, NCI Thesaurus)
Arachidonic acid has several possible fates, including oxygenation by lipoxygenases to make HPETEs (hydroperoxyeicosatetraenoic acids), or production of prostaglandin H2 by PGH2 synthase. 5-lipoxygenase acts with the membrane bound protein FLAP (five lipoxygenase activating protein) to produce the epoxide leukotriene LTA4 which is hydrolyzed to produce LTB4 or has glutathione added by a glutathione S-transferase to produce LTC4 and LTD4.

By exerting a chronotropic and inotropic effect, arbutamine mimics the cardiac stress caused by exercise that may prevent adequate tissue perfusion and oxygenation, and may provoke myocardial ischemia in patients with coronary artery disease.
(Arbutamine, NCI Thesaurus)
Utilizing a preterm sheep model, the team analyzed the response of fetal subplate neurons — cells that play a critical role in regulating preterm brain function and connectivity — to disturbances of brain oxygenation.

This agent may stimulate tumor necrosis and promote shunting of blood flow to viable regions of the tumor, increasing their oxygenation and rendering them more susceptible to the antitumor effects of hyperthermia and ionizing radiation.
(Mitoflaxone, NCI Thesaurus)
