| Saint Anthony's fire | Synonym: ergotism. 2. Any of several inflammations or gangrenous conditions of the skin (e.g., erysipelas). Origin: St. Anthony, Egyptian monk, about 250-350 A.D. (05 Mar 2000) |
| Anthony Nolan panel | A charitably funded register of volunteers willing to donate bone marrow if found to match a prospective bone marrow transplant patient who has no suitable related donor. It is the largest such register in the UK. (13 Nov 1997) |
| masked messenger RNA | <molecular biology> Long lived and stable mRNA found originally in the oocytes of echinoderms and constituting a store of maternal information for protein synthesis that is unmasked (derepressed) during the early stages of morphogenesis. In these early stages the rate of cell division is so rapid that transcription from the embryonic genome cannot occur. Undoubtedly not restricted to oocytes and the term can be applied to any mRNA which is present in inactive form. (18 Nov 1997) |

| messenger | 1. That which carries a message. 2. Having message-carrying properties. First messenger, a hormone that binds to a receptor on the surface cell and, in so doing, communicates with intracellular metabolic processes. Second messenger, an intermediary molecule that is generated as a consequence of hormone-receptor interaction; e.g., see adenosine 3',5'-cyclic monophosphate; guanosine 3',5'-cyclic monophosphate; calcium; inositide.

| messenger-like RNA | An ill-defined form of RNA, of high molecular weight, that never leaves the nucleus and is thought to be the precursor of messenger RNA. (05 Mar 2000) |
| messenger RNA | <molecular biology> Single stranded RNA molecule that specifies the amino acid sequence of one or more polypeptide chains. This information is translated during protein synthesis when ribosomes bind to the mRNA. In prokaryotes, mRNA is normally formed by splicing a large primary transcript from a DNA sequence and protein synthesis starts while the mRNA is still being synthesised. Prokaryote mRNAs are usually very short lived (average t 1/2 is 5mins.). In contrast, in eukaryotes the primary transcripts (HnRNA) are synthesised in the nucleus and they are extensively processed to give the mRNA that is exported to the cytoplasm where protein synthesis takes place. This processing includes the addition of a 5' 5' linked 7 methyl guanylate cap at the 5' end and a sequence of adenylate groups at the 3' end, the poly A tail, as well as the removal of any introns and the splicing together of exons, only 10% of HnRNA leaves the nucleus. Eukaryote mRNAs are comparatively long lived with a half life ranging from 30minutes to 24 hours. (27 Jun 1999) |

| second messenger | <molecular biology> In many hormone sensitive systems the systemic hormone does not enter the target cell but binds to a receptor and indirectly affects the production of another molecule within the cell, this diffuses intracellularly to the target enzymes or intracellular receptor to produce the response. This intracellular mediator is called the second messenger. Examples include cyclic AMP, cyclic GMP, IP3 and diacylglycerol. (18 Nov 1997) |
| second messenger systems | Systems in which an intracellular signal is generated in response to an intercellular primary messenger such as a hormone or neurotransmitter. They are intermediate signals in cellular processes such as metabolism, secretion, contraction, phototransduction, and cell growth. Examples of second messenger systems are the adenyl cyclase-cyclic AMP system, the phosphatidylinositol diphosphate-inositol triphosphate system, and the cyclic GMP system. (12 Dec 1998) |

| saint | 1. A person sanctified; a holy or godly person; one eminent for piety and virtue; any true Christian, as being redeemed and consecrated to God. "Them that are sanctified in Christ Jesus, called to be saints." (1 Cor. I. 2) 2. One of the blessed in heaven. "Then shall thy saints, unmixed, and from the impure Far separate, circling thy holy mount, Unfeigned hallelujahs to thee sing." (Milton) 3. One canonised by the church. [Abbrev. St] Saint Andrew's cross A cross shaped like the letter X. Chorea; so called from the supposed cures wrought on intercession to this saint. Origin: F, fr. L. Santcus sacred, properly p.p. Of sancire to render sacred by a religious act, to appoint as sacred; akin to sacer sacred. Cf. Sacred, Sanctity, Sanctum, Sanctus. Source: Websters Dictionary (01 Mar 1998) |
| Saint Ignatius' itch | <disease> A niacin deficiency disease (pellagra) caused by improper diet and characterised by skin lesions, gastrointestinal disturbances and nervousness. Depression, dermatitis, dementia and diarrhoea are common symptoms. (27 Sep 1997) |
| saint kitts and nevis | An independent federation of the leeward islands in the west indies, consisting of saint christopher, nevis, and sombrero. Its capital is basseterre. It was discovered by columbus in 1493, settled by the british in 1625, the first of the leeward islands to be colonised by them. It was held jointly by the french and english 1628-1713, but returned to great britain by the treaty of utrecht in 1713. It was held by the french 1782-83. Under the british for the next 200 years, it gained its independence in 1983. (12 Dec 1998) |
