Researchers found that fetal extrachromosomal circular DNA (eccDNA) in plasma was relatively hypomethylated compared to the maternal eccDNA. The methylation densities of eccDNA were also positively correlated with their sizes.

An Arterian wants to learn how other labs handle CSF transport to and between different lab sections. Do other labs allow CSF to be transported via pneumatic tube? If CSF is hand-carried instead, do providers carry all tubes to one central lab location, followed by the lab hand-carrying between different lab sections? And how do labs keep track of what went where?

What should be optimized and considered in the future?
