How can you use “populations” in a sentence? Here are some example sentences to help you improve your vocabulary:
Because of baseline variation in cell populations between batches of primary human monocytes isolated from multiple donors, cell culture experiments were performed in triplicate and data from representative experiments are presented.
Tumor-associated variation in one or several pan-T cell antigens is a typical feature of neoplastic lymphocytes in many T-cell malignances and has been termed antigen "loss" or "deletion" [ 7 ] . Using immunohistochemistry on a large bank of T-cell lymphomas, we have previously noted a frequency of such antigen deletion of 18% for CD2, 26% for CD3, 30% for CD5 and 68% for CD7 [ 8 ] . Flow cytometric analysis can allow a more sensitive assessment of subtle variations in the levels of surface marker expression than immunohistochemistry [ 9 ] . In non-neoplastic T-cell populations, we noted relatively narrow range of CD3, CD4 and CD5 expression with majority of cells clustering within one log intensity.
Such studies have important policy implications, since this information could assist policy makers and public health practitioners prevent epidemic urban malaria, and assist agencies in developing important information for populations most at risk.
This MARM mutant carries a point mutation that confers resistance to I1 Mab, but it is neutral otherwise [ 64 ] . Clonal interference occurs in asexual organisms when population sizes are large enough to allow the simultaneous generation of more than one advantageous mutation, so that the best mutation has to compete not only with an inferior wild type but also with the other fitter mutants [ 65 ] . Thus, while the best possible mutation should always be the one becoming dominant, the rate at which it does so should be slowed down in large populations.
Of the two ways described above in which MHC genotype may affect disease outcome, the first - association between a particular allele and disease outcome - has been repeatedly documented in human populations by various methods of genetic epidemiology [ 17 ] . The second kind of effect, more vigorous immune responses to a pathogen by a heterozygote as compared to homozygotes for the same alleles, which we term "allele-specific overdominance," has been suggested by several animal studies [ 18 19 20 21 ] , although none of these studies is unambiguous (see DISCUSSION).
