HCV heterosexual and perinatal transmission is uncommon in developed countries [15] [17], but modes of transmission might vary according to viral genotypes and genetic background of populations.
Moreover, for the interpretation of our results it should take into account the different genetic background of populations concerning HLA class II genes as well as the variable effect of known or unknown predisposing environmental factors.
One could speculate that the higher frequency detected in our series may be somehow due to the patients' origin or, in other words, to the different 'genetic background' of populations from the two studies.
This time period was selected because a system to collect data on the ethnic background of populations in the US was not in place until the late 1970's e at [ 17]; hence the 1980 date to ensure that system was well established.

Maps were drawn to display the geographic distribution of reported cases, against the background of population statistics from by-census 2006, obtained from the government's Census and Statistics Department.
However, our findings are not consistent with previous results [ 24, 27], possibly because the same variation in miRNA plays varying roles in diverse types of cancers, and the difference in ethnicity, regions, and background of population might have led to different consequences.
Adopt Berkshire's website says children in need of adoption "will reflect the racial, cultural and religious backgrounds of the populations within the areas from which they originate".
Countries in the so-called "Western" world, especially in Europe, witnessed a dramatic change in ethnic backgrounds of their populations starting in the last decennia of the last century.
But despite these gains, there is also evidence to indicate that the incidence of vaccine-preventable diseases is correlated to the socio-economic background characteristics of populations.
