| Ramsden circle | <microscopy> The circular spot of light formed at that distance above the eyepiece where the chief image forming rays cross, the back focal plane of the eyepiece. The objective back focal plane is in conjugate focus in this same plane. In visual microscopy, the point where the pupil of the eye is placed. (05 Aug 1998) |

| gel diffusion | Diffusion in a gel, as in the case of gel diffusion precipitin tests in which the immune reactants diffuse in agar. See: immunodiffusion. (05 Mar 2000) |
| gel diffusion precipitin tests | Precipitin test's in which the immune precipitate forms in a gel medium (usually agar) into which one or both reactants have diffused; generally classified in two types, in one dimension, and in two dimensions. Synonym: gel diffusion reactions. (05 Mar 2000) |
| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension). (05 Mar 2000) |
| gel diffusion precipitin tests in two dimensions | Precipitin test's made in a layer of agar that permits radial diffusion, in both of the horizontal dimensions, of one or both reactants. Double (gel) diffusion in two dimensions (Ouchterlony test, technique, or method) incorporates antigen and antibody solutions placed in separate wells in a sheet of plain agar, permitting radial diffusion of both reactants; this method is widely used to determine antigenic relationships; the bands of precipitate that form where the reactants meet in optimal concentration are of three patterns, referred to as reaction of identity, reaction of partial identity (cross-reaction), and reaction of nonidentity.

| venous circle of mammary gland | areolar venous plexus |
| Carus' circle | An imaginary curved line obtained from a mathematical formula, supposed to indicate the outlet of the pelvic canal. Synonym: Carus' circle. (05 Mar 2000) |
| vicious circle | The mutually accelerating action of two independent diseases or phenomena, or of a primary and secondary affection, the passage of food, after a gastroenterostomy, from the artificial opening through the intestinal loop by antiperistaltic action and back into the stomach again by the pyloric orifice, or the reverse. (05 Mar 2000) |
| passive diffusion | See: facilitated transport. (05 Mar 2000) |
| cerebral arterial circle | The roughly pentagonally shaped circle of vessels on the ventral aspect of the brain in the area of the optic chiasm, hypothalamus, and interpeduncular fossa. See: circle of Willis. (05 Mar 2000) |
| greater arterial circle of iris | An arterial circle at the ciliary border of the iris. Synonym: circulus arteriosus iridis major. (05 Mar 2000) |
| Ridley's circle | Dural venous formation which surrounds the hypophysis, composed of right and left cavernous sinuses and the intercavernous sinuses. Synonym: circulus venosus ridleyi, Ridley's circle. A venous sinus at the periphery of the placenta. Synonym: sinus venosus sclerae. (05 Mar 2000) |
| rolling circle | A mechanism for the replication of circular DNA. (05 Mar 2000) |
| rolling circle mechanism | <molecular biology> A mechanism of DNA replication in many viral DNAs, in bacterial f factors during mating and of certain DNAs in gene amplification in eukaryotes. DNA synthesis starts with a cut in the + strand at the replication origin, the 5' end rolls out and replication starts at the 3' side of the cut around the intact circular DNA strand. Replication of the 5' end (tail) takes place by the formation of Okazaki fragments. (18 Nov 1997) |
