The Editor in Chief has retracted this article after concerns were raised about noise patterns in Fig. 1 that appears to contain multiple partial overlaps. Additionally, the article mentions a blood sample collected from a human, but the authors did not provide an explanation of how this blood was collected and did not provide evidence that ethics approval had been obtained before the commencement of the study.

The authors did not state explicitly whether they agree to this retraction.
