| 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) |
|---|---|
| alkali denaturation test | A test for haemoglobin F (Hb F), based on the fact that haemoglobins, with the exception of Hb F, are denatured by alkali to alkaline haematin; the test is sensitive to 2% or more Hb F. (05 Mar 2000) |
| nucleic acid denaturation | Disorganization of secondary structures of nucleic acids through cleavage of hydrogen bonds and hydrophobic linkages. Denatured DNA appears to be a single-stranded flexible structure. The effects of denaturation on RNA are similar though less pronounced and largely reversible. (12 Dec 1998) |
| denaturation | Reversible or irreversible loss of function in proteins and nucleic acids resulting from loss of higher order secondary, tertiary or quaternary structure) produced by nonphysiological conditions of pH, temperature, salt or organic solvents. (18 Nov 1997) |
| denaturation temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |
| biochemical profile | A combination of biochemical tests usually performed with automated instrumentation upon admission of a patient to a hospital or clinic. (05 Mar 2000) |
| biophysical profile | <radiology> Parameters (30 minute observation period): reactive NST, foetal breathing movement: breathing period at least 60 seconds, foetal body movement, greater than 3 discrete movements of limbs/trunk, foetal tone: upper and lower limbs usually flexed with head on chest, greater than 1 episode of extension with return to flexion, amniotic fluid volume: largest pocket greater than 1 cm in vertical diameter without containing loops of cord score: 2 points if normal; 0 points for abnormal results: 8-10 = maximal score, 0-4 = severe foetal compromise; delivery indicated, 33% sensitivity; 17% positive predictive value (12 Dec 1998) |
| personality profile | A method by which the results of psychological testing are presented in graphic form, a vignette or brief personality description. (05 Mar 2000) |
| coagulation profile | A test which measures the speed of blood coagulation at different steps of the coagulation pathway. (27 Sep 1997) |
| profile | Vertical section of the soil through all its horizons and extending into the parent material. (09 Oct 1997) |
| profile record | A registration or record of the profile of a patient. (05 Mar 2000) |
| sickness impact profile | A quality-of-life scale developed in the united states in 1972 as a measure of health status or dysfunction generated by a disease. It is a behaviourally based questionnaire for patients and addresses activities such as sleep and rest, mobility, recreation, home management, emotional behaviour, social interaction, and the like. It measures the patient's perceived health status and is sensitive enough to detect changes or differences in health status occurring over time or between groups. (12 Dec 1998) |
| 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) |
| electrolyte profile | <biochemistry> A test which includes the measurement of the sodium, potassium, C02 and chloride concentrations in venous blood. (27 Sep 1997) |
