| gene cluster | A set of closely related genes that code for the same or similar proteins and which are usuallygrouped together on the same chromosome. (09 Oct 1997) |
| cluster analysis | A set of statistical methods used to group variables or observations into strongly inter-related subgroups. In epidemiology, it may be used to analyze a closely grouped series of events or cases of disease or other health-related phenomenon with well-defined distribution patterns in relation to time or place or both. (12 Dec 1998) |
| cluster headache | <symptom> A term used to describe a headache that is typified by constant, unilateral pain around the eye, with onset usually within 2-3 hours of falling asleep. Can be accompanied by a blocked nasal passage, runny nose, and-or tearing. One may also notice facial flushing, ptosis (dropping eyelid), facial swelling and constriction of the pupils. (27 Sep 1997) |
| cluster of differentiation | Cell membrane molecules that are used to classify leukocytes into subsets. CD molecules are classified by monoclonal antibodies. (05 Mar 2000) |
| cluster of differentiation 2 | A glycoprotein that is expressed on all peripheral T-cells, large granular lymphocytes and most, but not all, thymocytes. CD2 is involved in signal transduction and cell adhesion. (05 Mar 2000) |
| cluster of differentiation 3 | A complex of 5 polypeptides associated with the T-cell receptor and is involved in signal transduction. (05 Mar 2000) |
| cluster of differentiation 4 | A glycoprotein found on various subsets of T-cells, i.e., usually no helper and some T cytotoxic cells. (05 Mar 2000) |
| cluster of differentiation 8 | Membrane glycoprotein found on subsets of T lymphocytes. CD8 is expressed on T cytotoxic cells and T suppressor cells. Acronym: CD (05 Mar 2000) |
| egg cluster | One of the clumps of cells resulting from the breaking up of the gonadal cords in the ovarian cortex; these clumps later develop into primary ovarian follicles. (05 Mar 2000) |
| cluster h. |
a headache, possibly a type of migraine, characterized by attacks of unilateral excruciating pain over the eye and forehead, with temperature elevation, lacrimation, and rhinorrhea; attacks last from 15 minutes to about an hour and tend to occur in clusters, sometimes a few times a day for two to eight weeks followed by months or years without occurrence. Because attacks identical to the spontaneous attacks may be induced in sufferers by subcutaneous injection of histamine diphosphate, it is also known as histamine cephalalgia or h. See also chronic paroxysmal hemicrania, under hemicrania. Called also Horton's disease or syndrome, migrainous neuralgia, and vasomotor h.
