| electrophoresis, gel, pulsed-field | Electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length. (12 Dec 1998) |

| electrophoresis, gel, two-dimensional | Electrophoresis in which a second perpendicular electrophoretic transport is performed on the separate components resulting from the first electrophoresis. This technique is usually performed on polyacrylamide gels. (12 Dec 1998) |
| electrophoresis, polyacrylamide gel | Electrophoresis in which a polyacrylamide gel is used as the diffusion medium. (12 Dec 1998) |
| electrophoresis, starch gel | Electrophoresis in which a starch gel (a mixture of amylose and amylopectin) is used as the diffusion medium. (12 Dec 1998) |
| two dimensional gel electrophoresis | <technique> A high resolution separation technique in which protein samples are separated by isoelectric focussing in one dimension and then laid on an SDS gel for size determined separation in the second dimension. Can resolve hundreds of components on a single gel. (18 Nov 1997) |
| azo itch | Itching that occurs among workers in azo dyes. (05 Mar 2000) |
| baker's itch | An eruption on the hands and arms of bakers due to an allergic reaction to flour or other substances handled, or to the grain itch mite. (05 Mar 2000) |
| barber's itch | Tinea of the beard, occurring as a follicular infection or as a granulomatous lesion; the primary lesions are papules and pustules. Synonym: barber's itch, folliculitis barbae, ringworm of beard, tinea sycosis, trichophytosis barbae. (05 Mar 2000) |
| bath itch | Itching produced by inadequate rinsing off of soap or by overdrying of skin from excessive bathing. Synonym: bath itch, pruritus balnea. (05 Mar 2000) |
| mad itch | A highly contagious herpes virus infection affecting the central nervous system of swine, cattle, dogs, cats, rats, and other animals. (12 Dec 1998) |
| Malabar itch | An eruption consisting of a number of concentric rings of overlapping scales forming papulosquamous patches scattered over the body; it occurs in tropical climates and is caused by the fungus Trichophyton concentricum. Synonym: herpes desquamans, Malabar itch, Oriental ringworm, scaly ringworm, tinea tropicalis, Tokelau ringworm. (05 Mar 2000) |
| grain itch | A cutaneous eruption occasionally noted in farmers and grain handlers, caused by the action of the mite Pyemotes ventricosus. (05 Mar 2000) |
| rice itch | Schistosomiasis caused by schistosoma japonicum. It is endemic in the far east and affects the bowel, liver, and spleen. (12 Dec 1998) |
| grocer's itch | A vesicular dermatitis seen in grocers and bakers who handle sugar or flour; caused by a mite of the genus Glycophagus. (05 Mar 2000) |
| ground itch | Cutaneous larva migrans caused by larvae of hookworms. Synonym: ancylostoma dermatitis, ancylostomiasis cutis, coolie itch, dew itch, ground itch, swamp itch, swimmer's itch, toe itch, water itch, water sore. (05 Mar 2000) |
