| foramen lacerum medium | <anatomy> An irregular aperture, filled with cartilage (basilar cartilage) in the living, located between the apex of the petrous part of the temporal bone, the body of the sphenoid, and the basilar part of the occipital bones. Several structures pass along the margins of the foramen in a nearly horizontal direction but no structures pass through vertically. Synonym: foramen lacerum medium, lacerated foramen, sphenotic foramen. (05 Mar 2000) |
| ligamentum hyothyroideum medium | <anatomy> The central thickened portion of the thyrohyoid membrane. Synonym: ligamentum thyrohyoideum medianum, ligamentum hyothyroideum medium. (05 Mar 2000) |
| ligamentum tibiofibulare medium | The dense fibrous layer that connects the interosseous margins of the tibia and fibula, forming the upper portion of the tibiofibular syndesmosis and, with the bones and intermuscular septa, creating anterior and posterior comparments of the leg. Synonym: membrana interossea cruris, ligamentum tibiofibulare medium. (05 Mar 2000) |
| Loeffler's blood culture medium | A culture medium consisting of beef blood serum, sheep blood serum, and beef bouillon containing peptone, glucose, and sodium chloride; used for the isolation of Corynebacterium diphtheriae. (05 Mar 2000) |
| Lowenstein-Jensen culture medium | Primary mycobacterial recovery media composed of fresh whole eggs, defined salts, glycerol, potato flour, and malachite green (as an inhibitory agent). Synonym: Lowenstein-Jensen medium. (05 Mar 2000) |
| Lowenstein-Jensen medium | Primary mycobacterial recovery media composed of fresh whole eggs, defined salts, glycerol, potato flour, and malachite green (as an inhibitory agent). Synonym: Lowenstein-Jensen medium. (05 Mar 2000) |
| anterior white commissure | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies. (16 Dec 1997) |
| Bouffardi's white mycetoma | <dermatology> A form of mycetoma common in India and found occasionally in Somalia, caused by the organism Streptomyces somaliensis; in this variety, the muscles, tendons, and bones of the foot are destroyed by the disease process; numerous draining sinuses discharge yellowish grains, clustered like fish roe. (05 Mar 2000) |
| Brumpt's white mycetoma | Mycetoma caused by Pseudallescheria boydii, occurring in temperate and subtropical areas in India; small, white to yellow, hard to soft granules are discharged through the draining sinuses. (05 Mar 2000) |
| ventral white column | A narrow band of white substance bordering on the anterior median fissure of the spinal cord in front of the anterior gray commissure, and consisting of nerve fibres crossing over from one half of the spinal cord to the other. Synonym: commissura alba, anterior white commissure, commissura ventralis alba, ventral white column. (05 Mar 2000) |
| matter, white | The part of the brain that contains myelinated nerve fibres. The white matter is white because it is the colour of myelin, the insulation covering the nerve fibres. The white matter is as opposed to the gray matter (the cortex of the brain which contains nerve cell bodies). (12 Dec 1998) |
| May-White syndrome | <syndrome> Progressive myoclonus epilepsy with lipomas, deafness, and ataxia; probably a familial form of mitochondrial encephalomyopathy. (05 Mar 2000) |
| Vincent's white mycetoma | Mycetoma caused by Actinomadura madurae and occurring in North Africa, India, the Argentine, and Cuba. (05 Mar 2000) |
