Additionally, it is possible that a specific variant is not found, or found in an extremely low frequency in a specific population; as with the case of the TREM2 R47H variant in Asian [ 14, 15] or African American populations.
In addition, it shows an extremely low frequency of heterozygotes and has a very complex evolutionary history (Gentile et al. 2001 , 2002.
Among heterogeneous collections of sequences, the current applications of pyrosequencing have been to, either resolve the sequences from different organisms in the sample[7], [8] or be used to probe extremely low frequency variants existing within a single target[9] [12].
Electromagnetic extremely low frequency (ELF) waves play an important role in modulating the Earth's radiation belt electron dynamics.
Their results indicated that simultaneous use of static and extremely low frequency magnetic fields with an average intensity higher than 3.59 mT, significantly inhibited tumor growth, decreased tumor cell mitotic index, and lowered the proliferative activity.
Findings show an extremely low frequency of gender keywords used in reports to both conventions: of the 1,290 World Heritage Convention State of Conservation Reports analyzed, for example, only nine gender keyword mentions were found, and the keyword was the same for all references--women.
In this strain, endogenous Sup35 is soluble and spontaneous aggregation occurs with an extremely low frequency.
Studies demonstrated that both behaviors may significantly decrease over the habituation course to the novel tank [12], [24], or even occur with an extremely low frequency during the trial [18], [19], [39].
In green algae, mononucleotide TR motifs show an extremely low frequency (0.94% only) (Table S4).
Strikingly, there was an extremely low frequency of alterations disrupting CBX2 function.
The energy generated by an extremely low frequency electromagnetic field (ELF-EMF) is too weak to directly induce genotoxicity.
