| differential renal function test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |

| differential screening | Process in development of a multicellular organism by which cells become specialised for particular functions. Requires that there is selective expression of portions of the genome, the fully differentiated state may be preceded by a stage in which the cell is already programmed for differentiation but is not yet expressing the characteristic phenotype determination. (18 Nov 1997) |
| differential spinal anaesthesia | A form of diagnostic spinal anaesthesia producing blockade of different types of nerves in the subarachnoid space, based upon their differences in sensitivity to local anaesthetics; also observed during surgical spinal anaesthesia. (05 Mar 2000) |
| differential stain | <technique> A dye used to colour one portion of a tissue or cell which remained unaffected when the other part was stained by a dye of different colour. Synonym: differential stain. (05 Mar 2000) |
| differential thermal analysis | Technique by which phase transitions of chemical reactions can be followed by observation of the heat absorbed or liberated. (12 Dec 1998) |
| differential thermometer | <instrument, physics> An instrument for indicating changes of temperature without indicating the degree of heat by which it is affected; especially, an instrument contrived by Count Rumford which, as modified by Professor Leslie, was afterward called the differential thermometer. Origin: Thermo- + -scope. Source: Websters Dictionary (01 Mar 1998) |
| differential threshold | The smallest difference which can be discriminated between two stimuli or one which is barely above the threshold. (12 Dec 1998) |
| differential ureteral catheterization test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |
| differential white blood count | An estimate of the percentage of white blood cell types which make up the total white blood cell count. (05 Mar 2000) |
| differentiate | The process cells undergo as they mature into normal cells. Differentiated cells have distinctive characteristics, perform specific functions and are less likely to divide. See: dedifferentiate, undifferentiated. (16 Dec 1997) |
| differentiated | The similarity between a normal cell and the cancer cell, defines what degree of change has occurred. Cancer cells that are well differentiated are close to the original cell and are usually less aggressive. Poorly differentiated cells have changed more and are more aggressive. (09 Oct 1997) |
| differentiation | The distinguishing of one thing or disease from another. (18 Nov 1997) |
| differentiation antigen | Any large structural macromolecule that can be detected by immune reagents and that also is associated with the differentiation of a particular cell type or types. Many cells can be identified by their possession of a unique set of differentiation antigens. There should be no implication that the antigens cause differentiation. (18 Nov 1997) |
| differential |
derived function: the result of mathematical differentiation; the instantaneous change of one quantity relative to another; df(x)/dx relating to or showing a difference; "differential treatment" a quality that differentiates between similar things differential gear: a bevel gear that permits rotation of two shafts at different speeds; used on the rear axle of automobiles to allow wheels to rotate at different speeds on curves involving or containing one or more derivatives; "differential equation"

| differential |
A specification of the angular distribution of the electromagnetic energy scattered by a particle or a scattering medium. The differential (scattering) cross section is defined as the ratio of the intensity of radiant energy scattered in a given direction to the incident irradiance and thus has dimensions of area per unit solid angle. The symbol is frequently used for scattering cross section and d /d for the differential cross section.
