| CE | contractile element |
|---|---|
| CF | Contractile force |
| MCF | Myocardial contractile force |
| SREBP | 1/sterol regulatory element binding protein |
| TRE | 12-(O-tetradecanoylphorbol-13-acetate response element |
| peritubular contractile cells | Flattened smooth muscle-like cell's of mesodermal origin that lie just outside the basal lamina of the seminiferous tubule. Synonym: peritubular contractile cells. (05 Mar 2000) |
|---|---|
| contractile | Having the property of contracting. (05 Mar 2000) |
| contractile proteins | Proteins which participate in contractile processes. They include muscle proteins as well as those found in other cells and tissues. In the latter, these proteins participate in localised contractile events in the cytoplasm, in motile activity, and in cell aggregation phenomena. (12 Dec 1998) |
| contractile ring | The equatorial ring of microfilaments that diminishes in diameter probably both by contraction and disassembly as cytokinesis proceeds. (18 Nov 1997) |
| contractile stricture | A stricture due to the presence of contractile tissue which may be dilated but soon returns. Synonym: contractile stricture. (05 Mar 2000) |
| contractile vacuole | A specialised vacuole of eukaryote cells, especially Protozoa, that fills with water from the cytoplasm and then discharges this externally by the opening of a permanent narrow neck. Function is probably osmoregulatory. (18 Nov 1997) |
| amphoteric element | An element one or more of whose oxides unite with water to form hydroxides that may act as acids or as bases (e.g., aluminum). (05 Mar 2000) |
| anatomical element | Any anatomical unit, such as a cell. Synonym: morphologic element. (05 Mar 2000) |
| vessel element | Part of a xylem vessel in a higher plant, arising from a single cell. The end walls are perforated and may completely disappear, giving rise to a continuous tube. The remaining walls are thickened and lignified and there is no protoplast. (18 Nov 1997) |
| volume element | See: voxel. (05 Mar 2000) |
| P element | <molecular biology> A class of Drosophila transposon, widely used as a vector for reporter genes, for efficient germ line transformation and for enhancer trap or insertional mutagenesis studies. (18 Nov 1997) |
| mobile genetic element | <molecular biology> Small, mobile DNA sequences that can replicate and insert copies at random sites within chromosomes. They have nearly identical sequences at each end, oppositely oriented (inverted) repeats and code for the enzyme, transposase, that catalyses their insertion. Bacteria have two types of transposon, simple transposons that have only the genes needed for insertion and complex transposons that contain genes in addition to those needed for insertion. Eukaryotes contain two classes of mobile genetic elements, the first are like bacterial transposons in that DNA sequences move directly. The second class (retrotransposons) move by producing RNA that is transcribed, by reverse transcriptase, into DNA which is then inserted at a new site. (13 Nov 1997) |
| picture element | <microscopy> Any segment of a video scan line whose dimension along the line is equal to the line spacing. (05 Aug 1998) |
| morphologic element | Any anatomical unit, such as a cell. Synonym: morphologic element. (05 Mar 2000) |
| control element | Generic term for a region of DNA, such as a promoter or enhancer adjacent to (or within) a gene that allows the regulation of gene expression by the binding of transcription factors. (18 Nov 1997) |
