| pregnancy complications, parasitic | Parasitic diseases occurring during the course of pregnancy, or pregnancy during the course of a parasitic disease. Some of the more commonly co-occurring infections are amebiasis, malaria and toxoplasmosis. (12 Dec 1998) |
|---|---|
| skin diseases, parasitic | Skin diseases caused by arthropods, helminths, or protozoa. (12 Dec 1998) |
| intestinal diseases, parasitic | Infections of the intestines with a parasite. They are caused most commonly by intestinal nematodes (roundworms) and cestodes (tapeworms). (12 Dec 1998) |
| eye infections, parasitic | Mild to severe infections of the eye and its adjacent structures (adnexa) by adult or larval protozoan or metazoan parasites. (12 Dec 1998) |
| liver diseases, parasitic | Infections of the liver with a parasite. They are caused most commonly by trematodes (flukes). (12 Dec 1998) |
| lung diseases, parasitic | Infections of the lungs with a parasite. They are caused most commonly by nematodes (roundworms). (12 Dec 1998) |
| a-form DNA | <molecular biology> One of several forms that can be assumed by a double helix. A-DNA is stable in dehydrated conditions. This form is less common than the dominant form found under physiological conditions -- beta-DNA. This form is also assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA. It is a right-handed helix and is a more compact form than beta-DNA. (09 Oct 1997) |
| boat form | The less stable of two conformations assumed by 6-membered cyclic sugars (pyranoses) or cyclohexane derivatives, as opposed to chair form. See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| cavity preparation form | The configuration or shape of a cavity preparation. (05 Mar 2000) |
| replicative form | An intermediate stage in the replication of either DNA or RNA viral genomes that is usually double stranded, the altered, double-stranded form to which single-stranded coliphage DNA is converted after infection of a susceptible bacterium, formation of the complementary ("minus") strand being mediated by enzymes that were present in the bacterium before entrance of the viral ("plus") strand. (05 Mar 2000) |
| resistance form | The shape given to a cavity preparation that enables the dental restoration to withstand masticatory forces. (05 Mar 2000) |
| retention form | The shape of a cavity preparation that prevents displacement of the dental restoration by lateral or tipping forces as well as masticatory forces. (05 Mar 2000) |
| chair form | The more stable of two conformations assumed by 6-membered cyclic sugars (e.g., the pyranoses) or cyclohexane derivatives, as opposed to boat form. See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| wave form | The form of a pulse; e.g., an arterial pressure or displacement wave; or of the pacemaker pulse as demonstrated on the oscilloscope under a specified load. Synonym: waveshape. (05 Mar 2000) |
| wax form | A pattern of wax that, when invested and burned out or otherwise eliminated, will produce a mold in which a casting may be made. Synonym: wax form. (05 Mar 2000) |
