| FNA | Fine Needle Aspiration |
| stop-needle | A surgical needle, with the eye at the tip, the shank of which has a projecting shelf to arrest the needle when it has passed the desired distance through the tissues. (05 Mar 2000) |
|---|---|
| annular stop | <microscopy> The opaque ring-shaped stop with a small central opening usually placed in the objective back focal plane to provide dispersion staining. (05 Aug 1998) |
| central stop | <microscopy> An opaque disk placed in the ring carrier or diaphragm carrier of the substage apparatus. It excludes the central rays and is used for dark field work at low magnification. Variable stops can be contracted or expanded as desired. (05 Aug 1998) |
| stop | <dentistry> A bend or auxiliary attachment placed on a wire to limit the archwire from sliding or moving in the bracket slot of the bracket. (08 Jan 1998) |
| stop codon | <molecular biology> The three codons, UAA known as ochre, UAG as amber and UGA as opal, that do not code for an amino acid but act as signals for the termination of protein synthesis. They are not represented by any tRNA and termination is catalysed by protein release factors. There are two release factors in E. Coli, RF1 recognises UAA and UAG, RF2 recognises UAA and UGA. Eukaryotes have a single GTP requiring factor, eRF. See: ochre suppressor, amber suppressor. (13 Jan 1998) |
| stop-speculum | A dilating speculum, as a speculum of the eyelids, which is provided with a catch to prevent its being opened too wide. (05 Mar 2000) |
| dark field stop | <microscopy> A central stop for obtaining a dark field effect for low-power objectives. It is customarily used with a high numerical aperture, bright field condenser. (05 Aug 1998) |
| quick-stop mutant | A bacterial mutant that ceases replication immediately when the temperature reaches a certain level. Compare: temperature-sensitive mutant. (05 Mar 2000) |
| Krueger instrument stop | A mechanical device limiting the insertion of a root canal instrument into a canal. (05 Mar 2000) |
| artery needle | A blunt-pointed, curved needle, set in a handle, with the eye at the point, used for passing a ligature around an artery. (05 Mar 2000) |
| aspirating needle | A hollow needle used for withdrawing fluid from a cavity, when combined with an aspirator tube attached to one end. (05 Mar 2000) |
| atraumatic needle | An eyeless surgical needle with the suture permanently fastened into a hollow end. (05 Mar 2000) |
| biopsy needle | <equipment> A skinny needle that is passed percutaneously into an organ being investigated (liver and kidney are common). Tissue is obtained from the core of the needle and then analysed under the microscope. (21 Mar 1998) |
| biopsy, pleural needle | <investigation, procedure, surgery> A pleural needle biopsy involves the use of a needle (inserted from the skin) to obtain a small sample of pleural tissue for microscopic analysis. The biopsy is done using a local anaesthetic. Abnormal results may reveal cancer (metastatic or primary), tuberculosis, a fungal disease, viral disease, a parasitic disease or collagen vascular disease. Risks include pneumothorax and internal bleeding. (21 Mar 1998) |
| Veress needle | A needle equipped with a spring loaded obturator that is used for insufflation of the abdomen in laparoscopic surgery. (05 Mar 2000) |
| stop needle |
A needle with an eye at its tip, with a flange or shelf extending out from its shank end that prevents the needle from being inserted farther than the shelf.
