| population dynamics | <epidemiology> The pattern of any process, or the interrelationship of phenomena, which affects growth or change within a population. (12 Dec 1998) |
|---|---|
| population genetics | <epidemiology, genetics> The study of genetic influences on the components of cause and effect in the somatic characteristics of populations. (05 Mar 2000) |
| population growth | <epidemiology> Increase, over a specific period of time, in the number of individuals living in a country or region. (12 Dec 1998) |
| population pyramid | <epidemiology> Graphical representation of the age and sex composition of a population, constructed by computing the percentage distribution of the population in each age and sex class. (05 Mar 2000) |
| population surveillance | <epidemiology> Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy. (12 Dec 1998) |
| suburban population | The inhabitants of peripheral or adjacent areas of a city or town. (12 Dec 1998) |
| synchronous cell population | <cell culture> A culture of cells that all divide in synchrony. Particularly useful for certain studies of the cell cycle, cells can be made synchronous by depriving them of essential molecules, which are then restored. Synchronisation breaks down after a few cycles, however, as individual cells have unique division rates. (19 Jan 1998) |
| q in population genetics | The frequency of the less common of two different alternative (allelic) versions of a gene. (the frequency of the more common allele is p). (12 Dec 1998) |
| topotypical population | <zoology> Population occurring at the type locality from which the type specimen was taken. (09 Jan 1998) |
| urban population | The inhabitants of a city or town, including metropolitan areas and suburban areas. (12 Dec 1998) |
| retrospective studies | Studies used to test aetiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons. (12 Dec 1998) |
| pharmalogical studies | <pharmacology> Studies to assess the potential harmful or other effects of drugs (16 Dec 1997) |
| clinical studies | <pharmacology> Human studies that are designed to measure the safety, efficacy, and appropriate dosage of a new drug or biological. Clinical studies routinely involve the use of a placebo group that is given an inactive substance that looks like the test product. (14 Nov 1997) |
| cohort studies | Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesised to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics. (12 Dec 1998) |
| combination studies | <pharmacology> Studies in which a new drug is evaluated in combination with existing drugs. (09 Jan 1998) |
