| breath-holding test | A rough index of cardiopulmonary reserve measured by the length of time that a subject can voluntarily stop breathing; normal duration is 30 seconds or more; diminished cardiac or pulmonary reserve is indicated by a duration of 20 seconds or less. (05 Mar 2000) |

| uraemic breath | Characteristic odour of the breath in patients with chronic renal failure, variously described as "fishy," "ammoniacal," and "fetid," which is indicative of the systemic accumulation of volatile metabolites, usually excreted in the urine; dimethylamine and trimethylamine have been identified and correlated with the classic fishy odour.

| urea breath test | A test for the presence of the bacteria helicobacter pylori that causes inflammation and ulcers in the stomach. The breath test is based on the ability of h. Pylori to break down urea. Ten minutes after swallowing a capsule containing urea with labelled carbon, a breath sample is collected to detect labelled carbon in the exhaled breath. A positive test indicates active infection. The test turns negative after eradication of the bacteria from the stomach with antibiotics. (12 Dec 1998) |
| liver breath | A peculiar odour to the breath in persons with severe liver disease; caused by volatile aromatic substances that accumulate in the blood and urine due to defective hepatic metabolism. Synonym: liver breath. (05 Mar 2000) |
| polymorphism, single-stranded conformational | Variation occurring within a species in the conformation of denatured DNA fragments. These single-stranded DNA fragments are allowed to partially renature in a way that prevents the formation of double-stranded DNA. The fragments are run on polyacrylamide gels under various conditions to detect subtle changes in migration due to altered secondary structure. The resulting bands will align themselves if the fragments are the same, but will misalign if any point mutations are present. Sscps have been used in detecting mutations in various genes, such as oncogenes, tumour suppressor genes, and genes responsible for genetic diseases. (12 Dec 1998) |
