| addition polymer | <chemistry> A polymer which is formed from the fusion of two monomers which join completely without losing any small molecules. (15 Jan 1998) |
|---|---|
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| polymer | <chemistry> A macromolecule made of repeating (monomer) units or protomers. (18 Nov 1997) |
| polymer fume fever | An occupational disease marked by fever, pain in the chest, and cough caused by the inhalation of fumes given off by a plastic, polytetrafluorethylene, when heated. (05 Mar 2000) |
| Rambourg's periodic acid-chromic methenamine-silver stain | <technique> A stain for glycoproteins, used with an electron microscope, adapted from the Gomori-Jones periodic acid-methenamine-silver stain; it produces silver deposits in mature saccules of the Golgi apparatus, lysosomal vesicles, cell coat, and basement membranes. (05 Mar 2000) |
| paralysis, familial periodic | An autosomal dominant trait marked by recurring attacks of rapidly progressive flaccid paralysis. There are three types: I, associated with a fall in serum potassium levels (hypokalaemic periodic paralysis); II, associated with a rise therein (hyperkalaemic periodic paralysis, called also adynamia episodica hereditaria); and III, with normal levels (normokalaemic periodic paralysis). (12 Dec 1998) |
| Gomori-Jones periodic acid-methenamine-silver stain | <technique> A staining method using methenamine silver, periodic acid, gold chloride, haematoxylin, and eosin to delineate basement membrane, reticulin, collagen, and nuclei; used in renal histopathology. See: Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| periodic | Recurring at regular intervals of time. Origin: Gr. Periodikos (18 Nov 1997) |
| periodic acid | <chemical> Periodic acid (h5io6). A strong oxidizing agent. Chemical name: Periodic acid (H5IO6) (12 Dec 1998) |
| periodic acid Schiff reaction | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| periodic acid Schiff stain | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. Substances that can be demonstrated include carbohydrates, mucins, cartilage matrix, collagen, reticulum, basement membranes, fibrin, thyroid colloid, amyloid, glomerular hyaline deposits, and a number of other secretions or tissue constituents. Also used in for staining gels on which glycoproteins have been run. See: periodic acid Schiff reaction Synonym: PAS stain. (22 Sep 2002) |
| periodic arthralgia | A condition in which pain and swelling of one or more joints, most commonly the knee, occurs at regular intervals; there is sometimes abdominal pain, purpura, or oedema. Synonym: intermittent arthralgia. (05 Mar 2000) |
| periodic biopolymer | A biopolymer in which there are identical, repeating subunits. (05 Mar 2000) |
| periodic catatonia | Regularly reappearing phases of catatonic excitement. (05 Mar 2000) |
| periodic disease | A condition characterised by regularly recurring and intermittent episodes of fever, oedema, arthralgia, and gastric pain and vomiting, continuing for years without further development in otherwise healthy individuals. It is also called familial mediterranean fever. It does not refer to conditions in which episodes recur at regular intervals. (12 Dec 1998) |
