| ethnic group | A social group characterised by a distinctive social and cultural tradition maintained from generation to generation, a common history and origin and a sense of identification with the group; members of the group have distinctive features in their way of life, shared experiences and often a common genetic heritage; these features may be reflected in their experience of health and disease.

| experimental group | A group of subjects exposed to the variable of an experiment, as opposed to the control group. (05 Mar 2000) |
| family group | <zoology> The highest-ranking group of taxa whose names are regulated. The family group includes taxa at the ranks of superfamily, family, subfamily, tribe, and any other rank below superfamily and above the genus group that may be required, such as subtribe (09 Jan 1998) |
| ketole group | Carbons 1 and 2 of a 2-ketose (HOCH2CO-); trans-ketolation from d-xylose 5-phosphate to C-1 of aldoses is important in various metabolic pathways involving carbohydrates (e.g., photosynthesis, Dickens shunt); the two-carbon unit is transferred as a,beta-dihydroxyethyl thiamin pyrophosphate.

| uukuniemi group viruses | A group of viruses in the genus phlebovirus of the family bunyaviridae, infecting vertebrates and vectored by ticks. Its members have not been associated with human disease though antibodies have been isolated from human sera. (12 Dec 1998) |
| laramie group | <geology> An extensive series of strata, principally developed in the Rocky Mountain region, as in the Laramie Mountains, and formerly supposed to be of the Tertiary age, but now generally regarded as Cretaceous, or of intermediate and transitional character. It contains beds of lignite, often valuable for coal, and is hence also called the lignitic group. See Chart of Geology. Source: Websters Dictionary (01 Mar 1998) |
| lateral group of axillary lymph nodes | Lymph nodes along the brachial vein that receive lymph drainage from most of the free superior limb and send efferent vessels to the central group of axillary lymph nodes. Synonym: nodi lymphatici brachiales, brachial lymph nodes. (05 Mar 2000) |
| functional group | 1. <chemistry> The specific atom that give a biomolecule a specific chemical characteristic. 2. <ecology> This ecological term refers to groups of organisms that obtain energy in similar ways. Autotrophic plants fix energy from sunlight. Fungi and bacteria decompose organic matter. Shredders chew large particles like tree leaves. Scrapers rasp periphyton and microbes from solid surfaces. Collectors filter fine particles from the water or gather them from deposits. (05 Jan 1998) |
| linkage group | A set of two or more loci that have been shown by linkage analysis to be physically close in the genome but that have not yet been assigned to specific chromosomes. It is rapidly becoming an outmoded term. (05 Mar 2000) |
| llandeilo group | <geology> A series of strata in the lower Silurian formations of Great Britain; so named from Llandeilo in Southern Wales. See Chart of Geology. Source: Websters Dictionary (01 Mar 1998) |
| ludlow group | <geology> A subdivision of the British Upper Silurian lying below the Old Red Sandstone; so named from the Ludlow, in Western England. Source: Websters Dictionary (01 Mar 1998) |
| Almen's test for blood | Glacial acetic acid, gum guaiac solution, and hydrogen peroxide are added to an aqueous suspension of the suspected stain; if occult blood or blood pigment is present, a blue colour develops. Synonym: guaiac test, Schonbein's test, van Deen's test. (05 Mar 2000) |
| arterial blood | Blood that is oxygenated in the lungs, found in the left chambers of the heart and in the arteries, and relatively bright red. (05 Mar 2000) |
| arterial blood gas | A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. Acronym: ABG (17 Oct 1997) |
| blood | <haematology> Considered a circulating tissue composed of a fluid portion (plasma) with suspended formed elements (red blood cells, white blood cells, platelets). Arterial blood is the means by which oxygen and nutrients are transported to tissues, venous blood is the means by which carbon dioxide and metabolic by-products are transported for excretion.
