| absorptiometry, photon | A noninvasive method for quantitating bone mineral content. It is used especially in the diagnosis of osteoporosis and also in measuring bone mineralization in infants. (12 Dec 1998) |

| photon | <physics> A quantum unit of light energy. (09 Oct 1997) |
| photon density | The number of counted events recorded in scintigraphy per square centimeter or per square inch of imaged area. Synonym: count density. (05 Mar 2000) |
| single photon emission computed tomography | <radiology> Tomographic imaging of metabolic and physiological functions in tissues, the image being formed by computer synthesis of photons of a single energy emitted by radionuclides administered in suitable form to the patient. The method uses radionuclides which emit a single photon of a given energy. The camera is then rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer then reconstructs the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the target area scanned. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as the size and volume of the organ. The disadvantage is that, unlike positron emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of available photons and hence degrades the image.

| apolar interaction | <chemistry> The attractive force between molecules due to the close positioning of non-hydrophilic portions of the two molecules. (09 Oct 1997) |
| hydrophobic interaction | <chemistry> The attractive force between molecules due to the close positioning of non-hydrophilic portions of the two molecules. (09 Oct 1997) |
| specimen interaction | <microscopy> Reactions that occur inside the specimen when being struck with a beam of energetic electrons or ions. (05 Aug 1998) |
| specimen interaction volume | <microscopy> The volume inside the specimen in which all specimen interactions occur during electron beam irradiation. (05 Aug 1998) |
| DNA-protein interaction | <molecular biology> Any complex that forms between a protein molecule and DNA. Examples are nucleosomes (structures formed for the purpose of DNA storage) and any gene regulatory protein (a protein which regulates transcription by binding to a regulatory region on the DNA). (09 Oct 1997) |
| drug-drug interaction | The effects that occur when two or more drugs are used together. Such effects include changes of absorption in the digestive tract, changes in rate of the drugs' breakdown in the liver, new or enhanced side effects and changes in the drugs' activity. (09 Oct 1997) |
| drug interaction | <pharmacology> A chemical or physiologic reaction that can occur when two different medications are taken together and the interaction may affect the metabolism, effectiveness or toxicity of the other. (18 Jul 2002) |
| interaction | The quality, state or process of (two or more things) acting on each other. (18 Nov 1997) |
| interaction process analysis | In psychology, analysis of small group behaviour in terms of 12 specific categories, e.g., solidarity, tension release, agreement. (05 Mar 2000) |
