Cytokines and Myalgic Encephalitis

A study led by Dr. Mady Hornig director of translational research at the Center for Infection and Immunity and associate professor of epidemiology at Columbia's Mailman School on cytokines and Myalgic Encephalomyelitis (ME) is reported in Science Advances

ME is also known as Chronic Fatigue Syndrome.

The study was received for publication 19 November 2014, and accepted for publication 6 February 2015.

We report here distinct alterations in plasma immune signatures early in the course of ME/CFS (n = 52) relative to healthy controls (n = 348) that are not present in subjects with longer duration of illness (n = 246). Analyses based on disease duration revealed that early ME/CFS cases had a prominent activation of both pro- and anti-inflammatory cytokines as well as dissociation of intercytokine regulatory networks. We found a stronger correlation of cytokine alterations with illness duration than with measures of illness severity, suggesting that the immunopathology of ME/CFS is not static. These findings have critical implications for discovery of interventional strategies and early diagnosis of ME/CFS.

The progress in the conduct of the study was reported on April 22, 2014 in Pheonix Rising, a site that supports patients with ME.

Dr. W. Ian Lipkin, director of the Center for Infection and Immunity and professor of neurology and pathology at Columbia’s Mailman School, is reported as saying:

This study delivers what has eluded us for so long: unequivocal evidence of immunological dysfunction in ME/CFS and diagnostic biomarkers for disease.

As the headlines in the popular press are reporting, this study provides robust’ evidence that ME is a physical illness.

MarsEdit 4

I've been using MarsEdit for just over seven years. I started with version 2, and then upgraded to version 3 in 2010.Now, in 2018, I just upgraded to version 4.

Resistance Is Futile

Some of the trains that run from London Kings Cross to Cambridge divide at Cambridge. Part of the train goes on to Kings Lynn and the rest stops at Cambridge and does the run back to London. Perhaps it picks up other carriages coming from somewhere else, I don’t know but it seems likely.When you get on the train and before it sets off, there’s a public announcement announcing how the train divides. It explains that the train is composed of eight carriages and that passengers wanting to travel beyond Cambridge should ensure that they are in the front four carriages.The rear four carriages are of course nearest the barrier, so we choose to sit in one of those carriages if for no other reason than that we don’t have to walk so far to find a seat.So there we are and the voice comes over with the announcement. And then there is a pause and then a voice tells you what carriage you are in. So we hear ‘Six of Eight’ or ‘Seven of Eight’ – and every time I hear it I think of Star Trek, ‘Three o…

Business For Britain Is Concerned With Business For Britain

This report in the New York Times today


LONDON — Is British business fretting about the risks of the country drifting out of the European Union? Or does it crave a looser relationship with Continental allies, one free from meddlesome regulation?
The answer to that question remained unclear Monday after a newly formed group of business leaders argued for a renegotiation of Britain’s membership terms — echoing the policy of Prime Minister David Cameron, who in January promised voters a referendum on whether the country would remain in the Union.
The new group, called Business for Britain, is intended to counter the intervention of pro-E.U. business leaders who have warned of the dangers of Britain slipping out of the 27-nation bloc and its single market of 500 million people. A statement released Monday to announce the group’s formation was signed by about 500 executives.
I think this opinion in the New York Times article is interesting:

Never much attracted to the idea of European unity,…
