| cellular oncogene | <molecular biology> A normal gene that, when mutated or improperly expressed, can cause cancer to develop. (09 Oct 1997) |
|---|---|
| cellular pathology | The interpretation of diseases in terms of cellular alterations, i.e., the ways in which cells fail to maintain homeostasis, sometimes used as a synonym for cytopathology. (05 Mar 2000) |
| cellular polyp | A polyp that consists of benign neoplastic tissue derived from glandular epithelium. Synonym: cellular polyp, polypoid adenoma. (05 Mar 2000) |
| cellular respiration | <biochemistry> The conversion within the cell of nutrients (such as sugar molecules) into chemical energy in the form of ATP, by reacting the food with oxygen (O2) until the food has completely been degraded into carbon dioxide and H2O. (09 Oct 1997) |
| cellular retinoic acid binding protein | <protein> A cytoplasmic fatty acid binding protein that acts as an initial receptor for the putative morphogen, retinoic acid. (18 Nov 1997) |
| cellular slime mould | See: Acrasidae. (18 Nov 1997) |
| cellular tumour | A tumour composed mainly of closely packed cells. (05 Mar 2000) |
| immunity, cellular | Those manifestations of the immune response which are mediated by antigen-sensitised T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role. (12 Dec 1998) |
| acquired sensitivity | 1. <immunology> A state of hypersensitivity induced by exposure to a particular antigen (allergen) resulting in harmful immunologic reactions on subsequent exposures, the term is usually used to refer to hypersensitivity to an environmental antigen (atopic allergy or contact dermatitis) or to drug allergy. The original meaning, now obsolete, included all states of altered immunologic reactivity, immunity as well as hypersensitivity. Gell and Coombs used the term allergic reaction to mean any harmful immunologic reaction causing tissue injury. 2. <study> The medical specialty dealing with diagnosis and treatment of allergic disorders. (18 Nov 1997) |
| analytical sensitivity | The degree of response to a change in concentration of analyte being measured in an assay; synonymous with the detection limit. (05 Mar 2000) |
| antibiotic sensitivity | Microbial susceptibility to antibiotics. See: antibiotic sensitivity test, minimal inhibitory concentration. (05 Mar 2000) |
| antibiotic sensitivity test | The in vitro testing of bacterial cultures with antibiotics to determine susceptibility of bacteria to antibiotic therapy. (05 Mar 2000) |
| pacemaker sensitivity | The minimum cardiac activity required to consistently trigger a pulse generator. (05 Mar 2000) |
| relative sensitivity | The sensitivity of a medical screening test as determined by comparison with the same type of test; e.g., sensitivity of a new serological test relative to sensitivity of an established serological test. (05 Mar 2000) |
| chemotherapy drug sensitivity test | <investigation> A test to assess a cancerous tissue's response and vulnerability to chemotherapy drugs. This test can help predict a patients response to treatment and suggest which drugs may be useful. (16 Dec 1997) |
