| gastric filling defects | <radiology> Malignant tumours, carcinoma, lymphoma, leiomyosarcoma, metastases, benign, leiomyoma, lipoma, neurofibroma, polyp, hyperplastic, adenomatous, hamartomatous, others, bezoar, Nissen fundoplication, ectopic pancreas (12 Dec 1998) |
| ventricular filling pressure | The pressure in the ventricle as it fills with blood, ordinarily equivalent to the mean atrial pressure when there is no A-V valvular gradient. Atrial pressure can be used in place of transmural pressure because pericardial pressure usually varies between -2 and +2 mm Hg and hence is negligible. During cardiac tamponade, pericardial and atrial pressures equilibrate so that transmural pressure is zero and the high atrial presures cannot be "filling" pressures. (05 Mar 2000) |
| root canal filling materials | Materials placed inside a root canal for the purpose of obturating or sealing it. The materials may be gutta-percha, silver cones, paste mixtures, or other substances. (12 Dec 1998) |
| direct filling resin | An autopolymerizing resin especially designed as a dental restorative material. (05 Mar 2000) |
| oesophageal filling defect | <radiology> Tumour, carcinoma (oesophagus, stomach extending proximally), leiomyoma / leiomyosarcoma, polyp: fibrovascular, inflammatory, adenomatous, papilloma, carcinosarcoma, lymphoma, metastasis, oesophageal varix, extrinsic lesion (vascular impression, adenopathy, cyst), foreign body (12 Dec 1998) |
| end-filling | The use of DNA polymerase to create a blunt end (both strands are the same length and end together) on double-stranded DNA that has a staggered end (one strand is longer than the other so there is a single-stranded section at the end of the molecule). (09 Oct 1997) |
| uterine filling defect | <radiology> Technical, bubble, blood clot, mucoid material, congenital fold, pseudoadhesions / ridging -- folds long axis, neoplasm, submucosal leiomyoma, adenoma, endometrial carcinoma, pregnancy-related, pregnancy, molar pregnancy, retained conceptus, polyp, septated uterus, synechiae, IUD, iatrogenic (post-op) (12 Dec 1998) |
| filling | 1. That which is used to fill a cavity or any empty space, or to supply a deficiency; as, filling for a cavity in a tooth, a depression in a roadbed, the space between exterior and interior walls of masonry, the pores of open-grained wood, the space between the outer and inner planks of a vessel, etc. 2. The woof in woven fabrics. 3. Prepared wort added to ale to cleanse it. Back filling. See Back. Source: Websters Dictionary (01 Mar 1998) |
| filling defect | Displacement of contrast medium by a space-occupying lesion in a radiographic study of a contrast-filled hollow viscus, such as a polyp on a barium enema; also applied to defects in the otherwise uniform distribution of radionuclide in an organ, such as a metastasis in the liver on a 99mTc-sulfur colloid scan. (05 Mar 2000) |
| filling defect in renal collecting system | <radiology> Common causes: transitional cell carcinoma, blood clot, lucent calculus (urate) less common causes: fungus ball, sloughed papilla, fibroepithelial polyp, invasion by hypernephroma, malakoplakia, vessel impression, metastases (12 Dec 1998) |
| Bingham plastic | A material that, in the idealised case, does not flow until a critical stress (yield stress) is exceeded, and then flows at a rate proportional to the excess of stress over the yield stress; real materials probably only approach this ideal model. (05 Mar 2000) |
| modeling plastic | A thermoplastic material usually composed of gum damar and prepared chalk, used especially for making dental impressions. Synonym: impression compound, modeling composition, modeling compound. (05 Mar 2000) |
| plastic | 1. Having the power to give form or fashion to a mass of matter; as, the plastic hand of the Creator. "See plastic Nature working to his end." (Pope) 2. Capable of being molded, formed, or modeled, as clay or plaster; used also figuratively; as, the plastic mind of a child. 3. Pertaining or appropriate to, or characteristic of, molding or modeling; produced by, or appearing as if produced by, molding or modeling; said of sculpture and the kindred arts, in distinction from painting and the graphic arts.
