| dumbbell ganglioneuroma | <tumour> A ganglioneuroma in which the gross configuration resembles a dumbbell, e.g., two spheroidal masses connected by a narrow portion, usually the result of the neoplasm being somewhat molded by a resistant structure such as two ribs. (05 Mar 2000) |

| cardiac infarction | A term used to describe irreversible injury to heart muscle. Synonym: heart attack. See: infarction. Common symptoms include substernal, crushing chest pain that may radiate to the jaw or arms. Chest pains may be associated with nausea, sweating and shortness of breath. Acronym: MI (27 Sep 1997) |
| cerebral infarction | Infarction of brain tissue. (12 Dec 1998) |
| peri-infarction block | An electrocardiographic abnormality associated with an old myocardial infarct and caused by delayed activation of the myocardium in the region of the infarct; characterised by an initial vector directed away from the infarcted region with the terminal vector directed toward it. (05 Mar 2000) |
| watershed infarction | Cortical infarction in an area where the distribution of major cerebral arteries meet or overlap. (05 Mar 2000) |
| postmyocardial infarction pericarditis | <pathology> Inflammation of the pericardium. (18 Nov 1997) |
| postmyocardial infarction syndrome | <syndrome> A complication developing several days to several weeks after myocardial infarction; its clinical features are fever, leukocytosis, chest pain, and evidence of pericarditis, sometimes with pleurisy and pneumonitis, with a strong tendency to recurrence; probably of immunopathogenetic origin. (05 Mar 2000) |
| heart rupture, post-infarction | Rupture of the heart after myocardial infarction. (12 Dec 1998) |
| splenic infarction | Cell death (necrosis) of a portion or all of the spleen due to an interruption in blood flow. (27 Sep 1997) |
| infarction | 1. <cardiology> The formation of an infarct. 2. An infarct. Origin: L. Infarcire = to stuff in (18 Nov 1997) |
| a-form DNA | <molecular biology> One of several forms that can be assumed by a double helix. A-DNA is stable in dehydrated conditions. This form is less common than the dominant form found under physiological conditions -- beta-DNA. This form is also assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA. It is a right-handed helix and is a more compact form than beta-DNA. (09 Oct 1997) |
| boat form | The less stable of two conformations assumed by 6-membered cyclic sugars (pyranoses) or cyclohexane derivatives, as opposed to chair form. See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| cavity preparation form | The configuration or shape of a cavity preparation. (05 Mar 2000) |
| replicative form | An intermediate stage in the replication of either DNA or RNA viral genomes that is usually double stranded, the altered, double-stranded form to which single-stranded coliphage DNA is converted after infection of a susceptible bacterium, formation of the complementary ("minus") strand being mediated by enzymes that were present in the bacterium before entrance of the viral ("plus") strand. (05 Mar 2000) |
| resistance form | The shape given to a cavity preparation that enables the dental restoration to withstand masticatory forces. (05 Mar 2000) |
