    News from Aotearoa/New Zealand and the Pacific Islands

    Do report back if you can. And if you get a chance to ask, I would be interested to hear if Ros knows of any younger doctors coming through with a special interest in ME who may one day be able to fill her place.

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    As a general rule of thumb, ref is the original allele and usually the good one, and alt is the more recent mutation and usually the bad one. But, as I said: rule of thumb only, plus applies only to bad (pathogenic or risk) mutations. Many mutations don't do anything much (benign) so there it...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    You are perfectly right of course @Trish. None of us laypeople is going to work out the solution for a problem in such a complex biological system, no illusions there. I suspect one of the reasons we entertain ourselves with much happy speculating regardless is that we suffer from a couple of...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    This potential ME-trigger-to-tryptophan route is mighty confusing. On the one hand stressors and infections can upregulate IDO and TDO, potentially causing tryptophan to decrease. On the other hand certain infections (unfortunately the usual ME suspects were not tested in this study) are...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    I've only read the abstract which I interpret - in/correctly? - as not referring to tryptophan synthesis but only to tryptophan metabolism, i.e. the conversion of – presumably dietary - tryptophan into other metabolites such as kynurenic acid. Does the article itself say anything more? It's too...

    Machine Learning-assisted Research on ME/CFS

    @mariovitali What about TDO, do you know? That's in the liver I understand but the question is could it be downregulated by any of the typical ME triggers like EBV? Or could it be generally downregulated if there were the sort of liver problems you talk about? Edit: typo - corrected TPO to TDO

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    You ask a lot of good questions in your blog @Jenny TipsforME, so good I'd like to highlight just a few here. This had entered my mind, too. The way the hypothesis was presented I could understand how it could explain switching into – or out of – ME mode, a sudden on/off switch. Sure, this...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    You're welcome @paolo. I do enjoy your blog and often find it helpful when trying to get my head around a complex ME issue. Though in this particular case your mechanical analogy didn't work for me, too abstract for my way of thinking maybe? But I'm sure it's just perfect for somebody else; we...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    As I understand it the actual trap hypothesis is more concerned with IDO1 inhibition than TDO (plus of course the IDO2 fault) but if what you say about TDO is correct, @Stewart, that could certainly be one way to explain the initiation of the trap, which is exactly what my question was. For this...

    Stanford Community Symposium 2018: Phair, Metabolic traps, Tryptophan trap

    I have a possibly dumb question about the trap After watching Phair's presentation plus reading about it on a blog (https://paolomaccallini.com/2018/10/08/is-it-a-trap/) I think I understand the concept of the metabolic trap. What I don't understand is how it gets started. I get that there has...

    Will the relevant authorities/people see the recent re-analysis of the ME Cochrane review? Can somebody make sure they do? http://journals.sagepub.com/doi/full/10.1177/2055102918805187 Discussed here...

    OMF: Meet the team at the ME/CFS Collaborative Research Center at Harvard, funded by OMF

    Always nice to see the establishment of another ME research center, especially one featuring new (new to me anyway) names. The more the merrier! @mariovitali will find this one interesting: Jon Jacobs (my bolding) ;) Edit: corrected tag

    Top reasons ME research is an opportunity

    Yes, funding organisations are typically conservative but like to see themselves as progressive and cutting edge. That's why I think Moreau would likely be one of the few ticking both boxes. No idea, sorry. But somebody at the Stanford symposium said they thought possibly all the approaches...

    Top reasons ME research is an opportunity

    How about linking in with work done on microRNA by Prof Alain Moreau who recently presented his findings at Stanford and CMRC2018? Health Canada is likely to feel safer looking at options involving Canadian researchers already established and internationally respected in the field of ME...

    News from Aotearoa/New Zealand and the Pacific Islands

    Yes, I've always been a bit confused by Ros' statements, too. On the one hand she always mentions physiological underpinnings (more or less well researched) and how severe the illness can be. On the other hand she often expresses herself in a way that leaves you with an impression of all...

    NHS video Pilates for CFS (not a recommendation)

    This still happening except that when I added my 1 star - for lack of a zero star rating! - average rating of 1 star based on 1 rating of 4 stars and 21 ratings of 1 star. So it looks like people are trying to down vote this but it just keeps going back to the single 4 star rating. Could it be...

    BBC trust me I’m a doctor tests a placebo for back pain and sees significant results

    This thread reminded me of one of Cort's blogs discussing a connection between inflammation and the placebo effect. Note that the study this is based on is specific to depression (and that I haven't read the study and have zero idea of its quality): The Promise and Limitations of...

    Jarred Younger confirms neuroinflammation in brains of ME patients

    A couple of paragraphs jumped out at me in Cort's blog: Let's hope Jarred does get that money. Finding out what's happening in our brains after exertion - and coming at it from two angles, with Maureen Hanson doing the PET replication study - would be extremely interesting. Does anybody here...

    News from Scandinavia

    Article doesn't say much more than how nice it'll be for MUS patients on the island of Fyn to finally have their own Center to go to where they'll be understood. All very nice and caring but there's no indication whatsoever that anyone at the new center might take the biomedical side of things...
