| soil profile | A vertical section of the soil through all its horizons and extending into the parent material. (09 Oct 1997) |
|---|---|
| test profile | A combination of laboratory tests usually performed by automated methods and designed to evaluate organ systems of patients upon admission to a hospital or clinic. (05 Mar 2000) |
| thermal melting profile | In general a record of the phase state of a system over a temperature range. Phase changes can be detected by exothermy or endothermy. Valuable in studying lipid and DNA structures. (18 Nov 1997) |
| electrolyte profile | <biochemistry> A test which includes the measurement of the sodium, potassium, C02 and chloride concentrations in venous blood. (27 Sep 1997) |
| elution profile | <chemistry> A graph made to show how much material is being carried out of the column by the eluant in column chromatography over time. The graph will show a number of different peaks, each peak represents a different separated material from the original mixed substance. (09 Oct 1997) |
| facial profile | The outline form of the face from a lateral view, the sagittal outline form of the face. (05 Mar 2000) |
| kidney profile | <investigation> A test which includes the measurement of the blood urea nitrogen (BUN) and the creatinine in a venous specimen. This test allows the physician to make a determination of how effectively the kidneys are functioning. (27 Sep 1997) |
| urethral pressure profile | The continual recording of pressure through a hole in the side of a small catheter as it is pulled (at a constant rate while either water or a gas is infused through the hole) from a point within the bladder, through the vesical neck, and down the entire urethra; a form of resistance measurement which gives a tracing indicative of the functional length of the urethra and the points of maximal urethral resistance. (05 Mar 2000) |
| lipid profile | Pattern of lipids in the blood. (A lipid profile usually includes the total cholesterol, high density lipoprotein (hdl) cholesterol, triglycerides, and the calculated low density lipoprotein (ldl) cholesterol. (12 Dec 1998) |
| liver profile | <investigation> A test that measures the blood serum level of several enzymes produced by the liver. An elevated liver function test is a sign of possible liver damage. Examples include: prothrombin time, PTT, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, gamma glutamyl transpeptidase, alkaline phosphatase and serum albumin. (14 Oct 1997) |
| Lovibond's profile sign | The angle made at the meeting of the proximal nail fold and the nail plate when viewed from the radial aspect; normally, less than 180 |
| absolute system of units | A system based on absolute units accepted as being fundamental (length, mass, time) and from which other units (force, energy or work, power) are derived; such system's in common use are the foot-pound-second, centimeter-gram-second, and meter-kilogram-second system's. (05 Mar 2000) |
| absorbent system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |
| alimentary system | The organs that are responsible for getting food into and out of the body and for making use of food to keep the body healthy. These include the mouth, oesophagus, stomach, liver, gallbladder, pancreas, small intestine, colon, and rectum. (12 Dec 1998) |
| anterolateral system | A composite bundle of fibres, located in the ventrolateral part of the lateral funiculus, containing spinothalamic, spinohypothalamic, spinoreticular, and spinomesencephalic (spinotectal, spinal to periaqueductal grey, etc.) fibres; occupies the combined areas of the spinal white matter historically divided into anterior and lateral spinothalamic tracts; located in white matter ventral to the denticulate ligament, hence the anatomical basis for the anterolateral cordotomy; concerned with the transmission of nociceptive and thermal information and with crude (nondiscriminative) touch.
