| New World leishmaniasis | A grave disease caused by Leishmania braziliensis braziliensis, endemic in southern Mexico and Central and South America, except for the equatorial region of Chile; the organism does not invade the viscera, and the disease is limited to the skin and mucous membranes, the lesions resembling the sores of cutaneous leishmaniasis caused by L. Mexicana or L. Tropica; the chancrous sores heal after a time, but some months or years later, fungating and eroding forms of ulceration may appear on the tongue and buccal or nasal mucosa; many variants of the disease exist, marked by differences in distribution, vector, epidemiology, and pathology, which suggest that it may in fact be caused by a number of closely related aetiological agents. See: espundia. Synonym: American leishmaniasis, leishmaniasis americana, nasopharyngeal leishmaniasis, New World leishmaniasis. (05 Mar 2000) |

| new yellow enzyme | The d-amino-acid oxidase found in yeast, a flavoenzyme, which contains FAD as coenzyme instead of FMN as does NADPH dehydrogenase; so-called to distinguish it from Warburg's old yellow enzyme. Compare: amino acid oxidases. (05 Mar 2000) |
| New York Heart Association classification | A functional classification to assess cardiovascular disability. Class I: patients with cardiac disease without limitation of physical activity. Ordinary activity does not cause symptoms. Class II: patients with cardiac disease with slight limitation of activity; comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea or angina. Class III: patients with cardiac disease producing marked limitation of activity: comfortable at rest. Less than ordinary physical activity causes symptoms. Class IV: patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms may be present even at rest. (05 Mar 2000) |
| new zealand | A group of islands in the South Pacific Ocean. New Zealand flax. <botany> A myrtaceous shrub (Leptospermum scoparium) of new Zealand and Australia, the leaves of which are used as a substitute for tea. Source: Websters Dictionary (01 Mar 1998) |
| New Zealand mice | Inbred strains of mice, either black (NZB) or white (NZW), unique among strains used in experimental immunology because of their proclivity to spontaneous immunologic abnormalities and disorders including systemic lupus erythematosus similar to that found in humans. (05 Mar 2000) |
| investigational new drug | Status given an experimental drug after the FDA approves an application for testing it in people. (09 Oct 1997) |
| investigational new drug application | An application that must be submitted to a regulatory agency (the FDA in the united states) before a drug can be studied in humans. This application includes results of previous experiments; how, where, and by whom the new studies will be conducted; the chemical structure of the compound; how it is thought to work in the body; any toxic effects found in animal studies; and how the compound is manufactured. (12 Dec 1998) |
| behavioural genetics | The study of heritable factors in behavioural patterns, as by pedigree analysis, biochemical abnormality, or karyotypic analysis. (05 Mar 2000) |
| biochemical genetics | The study of genetics in terms of the chemical (biochemical) events involved, as in the manner in which DNA molecules replicate and control the synthesis of specific enzymes by the genetic code. (05 Mar 2000) |
| biometrical genetics | <study> The mathematical approach to the study of the inheritance of different phenotypes, or physical characteristics, as a result of plant or animal breeding. (09 Oct 1997) |
| Galtonian-Fisher genetics | The genetics of measurable traits determined by multiple loci which make contributions that are independent, additive, and approximately equal. Synonym: multilocal genetics. (05 Mar 2000) |
| galtonian genetics | The study of traits by analysis of the first two moments of metrical data; the preferred method for analysis of traits following the multivariate gaussian distribution. (05 Mar 2000) |
| palindrome in genetics | A palindrome is a word that reads the same in both directions as, for example, the names eve or anna. In genetics, a palindrome is a DNA or RNA sequence that reads the same in both directions. The sites of many restriction enzymes that cut (restrict) DNA are palindromes. Palindromic rheumatism is a form of joint inflammation whereby the joints involved appears to change periodically from one region of the body to another and back again. (12 Dec 1998) |
| variation (genetics) | The phenotypic differences among individuals in a population. (12 Dec 1998) |
| genetics | <study> The study of the patterns of inheritance of specific traits. (09 Oct 1997) |
