    Biomarker problems

    Recently there's been more news again of biomarkers claiming certain accuracies amongst patient groups of Long-Covid and ME/CFS patients and from my personal point of views there are usually several problems amongst these studies and the claims they make. The good studies that make these...

    Micro-RNA's in ME

    Since 2020 brought us four new publications on micro-RNA's (miRNA), I thought I'd start a thread to collect together the various discussions on micro-RNA's. Hopefully this will aid in the comparison of studies. Please feel free to add more studies or discussions as needed. The basics of...

    A nanoelectronics-blood-based diagnostic biomarker for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)

    New PNAS paper from Ron Davis and team released ahead of print (not open access). https://www.pnas.org/content/early/2019/04/24/1901274116 ABSTRACT. There is not currently a well-established, if any, biological test to diagnose myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The...

    Circulating extracellular vesicles as potential biomarkers in CFS/ME: an exploratory pilot study

    COMMENT: Wondering if these extracellular vesicles are that "something" that Ron Davis mentioned is different is the blood of people with SEID. Although the sample was small, the level of significance was pretty darn good. https://www.tandfonline.com/doi/full/10.1080/20013078.2018.1453730...
