| delivery system | A manmade system with the purpose of delivering a drug or another chemical directly into a cellular target, such as a via a manmade vesicle called a liposome. (09 Oct 1997) |

| delivery, vertex | In a vertex delivery, the top of the baby's head comes first. The vertex here refers to the top of the head The word vertex in Latin means a whirlpool, whirlwind, top of the mountain, or the top of the head. Why top of the head ? Because the hairs on the top of the head often form a whorl, a whirl-like pattern. (12 Dec 1998) |
| drug delivery | The method and route used to provide medication. (16 Dec 1997) |
| drug delivery systems | Systems of administering drugs through controlled delivery so that an optimum amount reaches the target site. Drug delivery systems encompass the carrier, route, and target. (12 Dec 1998) |
| targeted drug delivery | Delivering a drug to a specific site in the body where it has the greatest effect, instead of allowing it to diffuse to various sites, where it may cause damage or trigger side effects. (14 Nov 1997) |
| 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) |

| single-gene diseases | Hereditary disorders caused by a change (mutation) in a single gene. There are thousands of single-gene diseases including achondroplastic dwarfism, huntington disease, cystic fibrosis, sickle cell disease, duchenne muscular dystrophy, and haemophilia. Single-gene diseases typically describe classic simple mendelian patterns of inheritance (as autosomal dominant, autosomal recessive, and x-linked traits) by comparison with polygenic diseases. (12 Dec 1998) |
| single gene disorder | Hereditary disorder caused by a mutant allele of a single gene (for example, Duchenne muscular dystrophy, retinoblastoma, sickle cell disease). Compare: polygenic disorders. (09 Oct 1997) |
