Using statistical analysis, the researchers found that some mutations occurred at such high frequencies compared to other SNPs in the same populations that they must have improved survival and reproductive success and been the result of strong positive selection pressure.
IL-22 expression was also present in the same populations in normal skin (data not shown).
Additional sample sets may be needed for validation of initial studies both in the same populations as well as in other ethnic groups.
In the same populations of cortical neurons imaged in layer 4, we occasionally detected spontaneous coactivations of neurons, as described previously [6], [17].
In a repeated survey conducted in the same populations during 1993 to 1994, the mean total cholesterol level increased in Guangzhou but decreased in Beijing [14].
Reported HIV rates, where available, have been higher than among other men of reproductive age in the same populations, yet these men tend to have limited knowledge of the health related risks of anal intercourse [8] [10].
The comparable test on fourteen microsatellite loci in the same populations only identified one additional locus (RtSB3 [26]) that showed significant (without Bonferroni correction) frequency differences between Rv+ and Rv− populations (χ2 = 79.53, p<0.05).
Studies on serotypes distributions in Malaysia revealed differing outcomes probably due to the lack of consistent and continuous monitoring of the serotypes in the same populations, time interval between study, scale, and the geographical dissemination of the study.
However, the sum of the shortest ROH we consider here, from 0.5 1 Mb, is inversely correlated (r = –0.51; p = 0.00012) with estimates of male effective population size based on Y chromosome diversity in the same populations [13].
