| 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 |
| active length-tension curve | The relationship between active isometric tension and preload (rest length) for a contracting muscle. (05 Mar 2000) |
| amplified fragment length polymorphism | <technique> Invented by KeyGene, a Dutch biotech company based in Wageningen, Holland. The technique is now merchandised under licence agreement by Perkin Elmer. Selected markers are amplified in a PCR, which makes amplified fragment length polymorphism an easy and fast tool for strain identification in agriculture, botany, microbiology and animal breeding. Acronym: AFLP (05 Feb 1998) |
| arch length | The amount of space required for the permanent teeth as measured from the mesial aspect of the first molar on one side to the mesial aspect of the first molar on the opposite side, as measured through the contact points along an imaginary line of the dental arch. (05 Mar 2000) |
| arch length deficiency | The difference between the available circumference of the dental arch and that required to accommodate the succedaneous teeth in proper alignment. (05 Mar 2000) |
| available arch length | <dentistry> The amount of space available for the permanent teeth around the dental arch from the first permanent molar on the left to the first permanent molar on the right. (05 Mar 2000) |
| back focal length | <microscopy> As measured on the principal axis, from the second lens vertex to the back focal point of the lens. It is not the equivalent of the focal length. (05 Aug 1998) |
| bellows length | <microscopy> The distance from the eye point to the image plane in a photomicrographic apparatus. (05 Aug 1998) |
| bond length | This is the distance between the nuclei of two atoms which have formed bonds with each other. (09 Oct 1997) |
| passive length-tension curve | The relationship between passive tension and preload (rest length) for a muscle at rest. (05 Mar 2000) |
| required arch length | The sum of the mesiodistal widths of the permanent teeth from first permanent molar to first permanent molar. (05 Mar 2000) |
| resting length | The length at rest from which a muscle develops maximum isometric tension. (05 Mar 2000) |
| restriction fragment length polymorphism | <molecular biology, technique> A method that allows familial relationships to be established by comparing the characteristic polymorphic patterns that are obtained when certain regions of genomic DNA are amplified (typically by PCR) and cut with certain restriction enzymes. The variation in the length of DNA fragments produced by a restriction endonuclease that cuts at a polymorphic locus. Such variations are generated by mutations that create or abolish recognition sites for these enzymes. This is a key tool in DNA fingerprinting, reflecting the existence of different alleles in the individual. Restriction fragment length polymorphism mapping is also used in plant breeding to see if a key trait such as disease resistance is inherited. In principle, an individual can be identified unambiquously by restriction fragment length polymorphism hence the use of restriction fragment length polymorphism in forensic analysis of blood, hair or semen). Similarly, if a polymorphism can be identified close to the locus of a genetic defect, it provides a valuable marker for tracing the inheritance of the defect. Synonym: DNA fingerprinting.
