The phrase "a periodical pattern of" is correct and usable in written English.
It can be used when describing something that occurs at regular intervals or follows a recurring sequence.
Example: "The study revealed a periodical pattern of rainfall that significantly affected the local agriculture."
Alternatives: "a recurring pattern of" or "a regular pattern of".
These results may have clinical significance given that in chronic inflammatory airway diseases increased acetylcholine release is observed in a periodical pattern, for example during asthma attacks [ 2].
In this study we examined the impact of WRN on telomeric substrates with a 3' single-stranded overhang in vitro and show that WRN has sequence-specific exonuclease activity that removes several nucleotides inward with a periodical pattern from the 3' end of the telomeric overhang.
Second, we use the Fisher's G-test to examine whether the expression or activity of a TF behaves like a pure random process or whether it shows a periodical pattern.
The accuracy of DFT-based methods is easily biased by the length variation of the repeat units caused by mutations or INDELs, as this will weaken the periodical pattern of the transformed Fourier spectral amplitudes.
Our model suggests that the periodical pattern of cell cycle genes is largely coded in their promoter regions, which can be captured by motif and transcription factor binding data.
The periodical patterns of nucleotide variability suggest the location of nucleosomes that are phased at TSS, and can be viewed as the genetic footprint of the chromatin state that has been maintained throughout mammalian evolutionary history.
These iRASs show a significant periodical pattern (P = 3e-10, Fisher's G test), while the expression levels of E2F4 do not (P >0.1, Fisher's G test).
The sequence divergence of the same genomic region between humans and chimpanzees also revealed a similar periodical pattern.
