| DNAse i hypersensitivity site | <molecular biology> A site on a DNA molecule that is especially prone to being cut apart by the endonuclease enzyme DNase I, which breaks down DNA into smaller fragments by cleaving phosphodiester bonds. These sites tend to be near active genes, which are regularly transcribed. (09 Oct 1997) |
|---|---|
| trophoblastic tumour, placental site | A tumour that arises from the trophoblast of the placental bed and is composed mainly of cytotrophoblastic cells. It encompasses lesions of low- and high-grade malignancy. (holland et al., cancer medicine, 3d ed, p1691) (12 Dec 1998) |
| expression site | The location in the genome of the gene for the variable surface glycoprotein that is currently being expressed (an expression-linked copy) by the trypanosome (a parasitic protozoan which causes the disease African sleeping sickness). most of these sites are near the ends, or telomeres, of a chromosome. (09 Oct 1997) |
| upstream activation site | A DNA sequence that regulates transcription like an enhancer but does notwork if its located downstream from a promoter. (09 Oct 1997) |
| fragile site | Places on chromosomes that tend to break more often than other places. These places also tend to be where chromosomal translocations (a type of chromosomal mutation) occur. (09 Oct 1997) |
| ligand binding site | The site on a protein's surface that binds a ligand; equivalent to the active site if the ligand is the substrate of an enzyme. (05 Mar 2000) |
| adult tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| aerogenic tuberculosis | Infection with the Mycobacterium tuberculosis spread by inhalation of infected droplets. (05 Mar 2000) |
| anthracotic tuberculosis | <chest medicine> Fibrosis and scarring of the lungs secondary to the repeated inhalation of dust associated with some occupation. Examples include silica, asbestos and coal dust exposure. (29 Oct 1998) |
| arrested tuberculosis | A scar or a calcified, fibrous, or caseous nodule in the lung pleura, lymph node, or other organ, resulting from previous tuberculosis that has regressed; reactivation is possible. Synonym: arrested tuberculosis, inactive tuberculosis. (05 Mar 2000) |
| attenuated tuberculosis | A mild chronic form marked by caseous tubercles of the skin and the occurrence of cold abscesses. (05 Mar 2000) |
| basal tuberculosis | Tuberculosis of the basilar portions of the lungs. (05 Mar 2000) |
| general tuberculosis | Usually a chronic tuberculosis infection where spread of the original primary infection has occurred via the patients lymphatic system (or bloodstream). Disseminated disease occurs primarily in the immunocompromised individual (for example AIDS, cancer patient). The elderly are at increased risk for dissemination. In disseminated disease, organs and tissues that can be affected include pericardium, peritoneum, larynx, bronchus, bone, joints, lymph nodes, stomach, meninges, eyes, kidneys and skin. Treatment is with INH, rifampin, ethambutol and other antibiotics. (27 Sep 1997) |
| reinfection tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| cerebral tuberculosis | Inflammation of the cerebral leptomeninges marked by the presence of granulomatous inflammation; it is usually confined to the base of the brain (basilar meningitis, internal hydrocephalus) and is accompanied in children by an accumulation of spinal fluid in the ventricles (acute hydrocephalus). Synonym: cerebral tuberculosis. (05 Mar 2000) |
