| prion protein | Small, infectious proteinaceous particle, of non-nucleic acid composition because of its resistance to nucleases; the causative agent, either on a sporadic, genetic, or infectious basis, of six neurodegenerative diseases in animals, and four in humans; the latter include the spongiform encephalopathies of kuru, Creutzfeldt-Jakob disease, Gerstmann-Straussler-Scheinker syndrome and fatal familial insomnia. The gene encoding for the PrP is found on chromosome 20. Synonym: prion. (05 Mar 2000) |

| prions | See: PrP, Gerstmann Straussler Scheinker syndrome. Suggested as the causative agents of several infectious diseases such as scrapie (in sheep), kuru and Creutzfeld Jakob disease in man. Prions (proteinaceous infective particles) apparently contain no nucleic acid. The 27 kD protein of scrapie is related to a normal cell protein and may possibly cause its over production.

| prior | The superior of a priory, and next below an abbot in dignity. Conventical, or Conventual, prior, a prior who is at the head of his own house. See the Note under Priory. Claustral prior, an official next in rank to the abbot in a monastery; prior of the cloisters. Origin: OE. Priour, OF. Priour, prior, priur, F. Prieur, from L. Prior former, superior. See Prior.

| prior probability | The best rational assessment of the probability of an outcome on the basis of established knowledge before the present information is included. For instance, the prior probability of the daughter of a carrier of haemophilia being herself haemophiliac is 1/2. But if she already has one child, an affected son, the posterior probability that she is a carrier is unity, whereas if she has one child, a normal one, the posterior probability that she is a carrier is 1/3. See: Bayes theorem. (05 Mar 2000) |
| priory | Origin: Cf. LL. Prioria. See Prior. A religious house presided over by a prior or prioress; sometimes an offshoot of, an subordinate to, an abbey, and called also cell, and obedience. See Cell. Of such houses there were two sorts: one where the prior was chosen by the inmates, and governed as independently as an abbot in an abbey; the other where the priory was subordinate to an abbey, and the prior was placed or displaced at the will of the abbot. Alien priory, a small religious house dependent on a large monastery in some other country. Synonym: See Cloister. Source: Websters Dictionary (01 Mar 1998) |
| prism | <microscopy> A transparent body with at least two polished plane faces inclined with respect to each other, from which light is reflected or through which light is refracted. When light is refracted by a prism whose refractive index exceeds that of the surrounding medium, it is deviated or bent toward the thicker part of the prism. (05 Aug 1998) |
| prism bar | A graduated series of prism bar's mounted on a frame and used in ocular diagnosis. (05 Mar 2000) |
| prism cover test | Measurement of the deviation in strabismus by the alternate cover test combined with neutralization for the deviation using prisms. (05 Mar 2000) |
| prism diopter | The unit of measurement of the deviation of light in passing through a prism, being a deflection of 1 cm at a distance of 1 m. (05 Mar 2000) |
| prism illuminator | <microscopy> A 45 to ~0-degree prism interposed in the tube of a light microscope for the purpose of directing an intense beam of light through the objective onto the object. The prism illuminator utilises about one half the aperture of the objective as does the mirror illuminator with an attending loss of resolution over that obtainable with either a plane glass illuminator or a pellicle mirror. See: metallography, Nicol prism. (05 Aug 1998) |
| prism vergence test | Measurement of the amplitude of fusion by placing prisms of gradually increasing power in the direction tested until diplopia occurs. (05 Mar 2000) |
| prisma | A structure resembling a prism. Origin: G. Something sawed, a prism (05 Mar 2000) |
| prismata adamantina | The calcified, microscopic rods radiating from the surface of the dentin, forming the substance of the enamel of a tooth. Synonym: enamel fibres, enamel prisms, enamel rods. (05 Mar 2000) |
| prismatic | Relating to or resembling a prism. (05 Mar 2000) |
| prismatical | 1. Resembling, or pertaining to, a prism; as, a prismatic form or cleavage. 2. Separated or distributed by a prism; formed by a prism; as, prismatic colours. 3. <chemistry> Same as Orthorhombic. <chemistry> Prismatic borax, borax crystallized in the form of oblique prisms, with ten molecules of water; distinguished from octahedral borax. <optics> Prismatic colours, the spectrum produced by the passage of light through a prism. Origin: Cf. F. Prismatique. Source: Websters Dictionary (01 Mar 1998) |
