| fluctuation test | <investigation> Test devised by Luria and Delbruck to determine whether genetic variation in a bacterial population arises spontaneously or adaptively. In the original version the statistical variance in the number of bacteriophage resistant cells in separate cultures of bacteriophage sensitive cells was compared with variance in replicate samples from bulk culture. The greater variance in the isolated populations indicates that mutation occurs spontaneously before challenge with phage. (The proportion of resistant cells depends upon when after isolation the mutation arises which will be very different in separate populations). (18 Nov 1997) |

Fluidus, fr. Fluere to flow: cf. F. Fluide. See Fluent. A fluid substance; a body whose particles move easily among themselves. Fluid is a generic term, including liquids and gases as species. Water, air, and steam are fluids. By analogy, the term is sometimes applied to electricity and magnetism, as in phrases electric fluid, magnetic fluid, though not strictly appropriate. Fluid dram, or Fluid drachm, a measure of capacity equal to one eighth of a fluid ounce. Fluid ounce. In the United States, a measure of capacity, in apothecaries' or wine measure, equal to one sixteenth of a pint or 29.57 cubic centimeters. This, for water, is about 1.04158 ounces avoirdupois, or 455.6 grains. In England, a measure of capacity equal to the twentieth part of an imperial pint. For water, this is the weight of the avoirdupois ounce, or 437.5 grains. Fluids of the body. <physiology> The circulating blood and lymph, the chyle, the gastric, pancreatic, and intestinal juices, the saliva, bile, urine, aqueous humor, and muscle serum are the more important fluids of the body. The tissues themselves contain a large amount of combined water, so much, that an entire human body dried in vacuo with a very moderate degree of heat gives about 66 per cent of water. Burning fluid, Elastic fluid, Electric fluid, Magnetic fluid, etc. See Burning, Elastic, etc. Source: Websters Dictionary (01 Mar 1998) |
| fluid bilayer model | Generally accepted model for membranes in cells. In its original form, the model held that proteins floated in a sea of phospholipids arranged as a bilayer with a central hydrophobic domain. Although it is now recognised that some proteins are restrained by interactions with cytoskeletal elements and that the phospholipid annulus around a protein may contain only specific types of lipid, the model is still considered broadly correct. (18 Nov 1997) |
| fluid mosaic model | A model used to conceptualise cell membranes, in it, the membranesare described as a structually and functionally asymmetric lipidbilayer studded with embedded proteins that aid in cross-membrane transport. (09 Oct 1997) |
| fluid retention | An abnormal accumulation of fluid in cells, tissues or body cavities that results in swelling. (16 Dec 1997) |
| fluid retinopexy | A procedure to repair a detached retina by holding it in place with a fluid that is heavier than vitreous fluid. (05 Mar 2000) |
