Jan have you heard of aquaporin? - the water channels in cell membranes.
Abstract about them ...

glutamine can convert to glutamate in one step, but NAG is a sugar(even though it's made from glutamine), that is involved in tissue rebuilding (especially gut wall).

Ray, can you help me with this kinesiology concept? You are not the first person whose opinion I respect who trusts kinesiology. But my mind just can't grasp the science of it. If there was some sort of scientific explanation... I had a flaky woman (not flaky because of kinesiology - just flaky in general) once hold a bottle of some supplement up to me (through my coat and clothes if I remember correctly) and then made me hold my thumb and first finger together and she used the effort to pull them apart as the determining factor as to whether or not I needed the supplement. She wasn't very impressive, to say the least. But I have heard of so many trustworthy people relying on it to completely discredit it. Thanks in advance.

>My understanding is almost all of this pathways work BOTH ways, depending on the relative concentration gradients. I think there are a few that ONLY work in one way.., I think they say these are irreversible, but I'm not sure.
The enzymes act as catylsts to speed up the reactions ..mostly I think by lowering the thresholds for the reactions to occur, so that more converts along the pathways. I think they speed up reactions too though.
I'm not sure if the enzymes work in both directions or not?
So with say tyrosine, you add some in your body..this makes it way higher than the dopamine..so it converts..then if the dopamine is higher than the adrenaline..it will convert until the dopamine and adrenaline are in balance I guess. If you already have lots of adrenaline, it should stay as dopamine..but I suspect you always get a bit of conversion anyway.As I think you've worked out..its the adrenaline thats limits how much tyrosine one can take...or the thyroid hormones .
The tyrosine also goes into thyroid hormones along the pathway somewhere too. ..so if you are low of them it should shunt off that way too.
As I already take some thyroid hormones most of my tyrosine seems to go to the dopamine pathway..and then some to adrenaline..which limits me. Although some still converts to thyroid hormones...wch makes tyrosine a problem in those already on enough thyroid hormones, or who are hyperthyroid.
I doubt any adrenaline would convert back as adrenaline gets used up fairly quickly doesn't it? Not sure but I think it stimulates cortisol to lower it?
But if adrenaline is used up like that , it would make the amount of adrenaline relatively low which would make your body always favour converting some into adrenaline.
o I don't know what I'm talking about here, just how I THINK it may work.Now if you have low adrenals this may be fine, unless they need a rest I guess.
Anyway I think the answer to your question is yes they go both ways..but not usually.
I even suspect with me tyrosine may go to PEA as well<g>, but I haven't looked at that pathway lately.
The converions are sooo much mostly one way that everyone just assumes they only go one way.
I'm pretty sure I don't go the "right" way always too with these pathwaysIt has to do with whether you have enough of all the enzymes and cofactors as well as how much of the substrates(the relative concentration gradients) you have etc..which is why P5P is an important one with me.
Its also why you have to take supplements as a "group" and why usually just taking one thing doesn't work unless that was all you were short on.Jan

> Think I'm out of my depth here! This abstract says that hyperthyroid increases bladder emptying, hypo reduces....but not in your case! saw some references to antidepressants, inhibiting bladder emptying because of receptors for monoamine neurotransmitters in the bladder, and also the antagonism of acetylcholine.
Ray, thank you so much for looking at this and getting back to me. I feel "upset" about all of this at present.
It's just that when I described what happened to this bladder nurse, she said that's what happens to some people on cholinergic drugs. Before this, all I drew was a blank from the docs.
(The problem with this is caus I didn't get catherised my bladder got overstretched, but really get off topic <g>)
I looked up cholinergic drug reaction and bladder and got this yesterday
----------------------------------------
"acetylcholinesterase (AChE), an enzyme of fundamental interest for its biological activity and its special biophysical properties. It acts very rapidly to stop neurotransmission at cholinergic synapses like those found in the brain and at neuromuscular junctions--consistent with the need for speedy responses in the neuromuscular system.
Competitive inhibition: A competitive drug can compete with the substrate for the active site of the enzyme. If the drug bind to the enzyme site it prevents binding of the normal substrate. The drug will just occupy the active site and then leaves it unchanged. Another drug or a substrate will then take its place. The action of the enzyme is slowed down by the number of times it get occupied by a competitive substance.Drugs can exert their effects by an interaction with an enzyme and therefore altering a physiological response. The neurological disorder myathenia gravis, for example, is characterized by profound muscle weakness due to acetylcholine deficiency. The cholinergic drug neostigmine is used to interfere with inactivation of acteylcholine by acetylcholinestrease at the neuromuscular junction."
---------------------------------------So that means if I had a cholinergic drug type reaction to the T3 somehow the acetylcholine must have been increased maybe?
But then most hypothyoids on thyroid replacement or before any meds complain of "brain fog"...inability to think of the right word, almost non existent memory etc.. supposed to get better when you get your levels right and your brain starts getting repaired I guess
Mine was bad but went worse on Armour(T4/T3 pig's thyroid that has a higher T3:T4 ratio than human) only..adding in T4 seems to make it a bit better(hopefully).So his means the Armour must have reduced my acetylcholine, as that's what is needed for memory isn't it? I guess it's more complicated than just one neurotransmitter.
My reaction time is better on Armour than before although nowhere near normal..so that means acetylcholinesterase is increased I guess?
Muscular strength slowly improving too..although still not normal. In fact that "vitality and longevity test" picked that up too "active tissue mass is 68% of ideal"<g>..I'm surprised it picked up what it did. I agree with its readings too.
(I've been on Armour for 3 years now, and added T4 slowly for a year)I noted as I added the T4 my bladder control stuff lessened but my memory improved.
I know, I'm strange. I'm not a typical hypothyroid. I think if I'd known about tyrosine and some of these other helpful coenzymated B's and other products you mentioned etc I may not have needed thyroid hormones...but when started I didn't. Still hopeful one day I can work it out and get fixed up.
> Nitric oxide appears to be important...Well I seem to have strange reactions with NO/nitrates/nitrites too ..started last September after a dental anaesthetic. (I think it's all here back in October 2003)
I seem to be able to eat some bacon now. Our bacon is not as good as the dry cured stuff I got in Britain though.>

I haven't tried mannose.
My bladder and my gut to my knowledge seem just fine..gee something is<g>.
The problem with my bladder is ..as I did what the docs, physios etc said to do and held on like + that time when I first started on Armour and wasn't advised to go to emergency(and didn't know)..well if your bladder stretched too much if loses its elasticity and you need catheters etc.
Apparently I'm luckier than most, but if I don't stop stretching it , I'll have to catherize all the time...yuk ..so I have to cut down on water intake> >

I also found a bottle of coenzymate B complex sublinguals which I started a couple of days ago too.

Betaine and taurine are also 'osmolytes'.Well it look like when I put my order in o'seas I need some betaine, probably TMG from what you found?

>actually sound exactly what I need..something else get from O'seas somewhere? I remember reading this yesterday, but I've forgotten now. I was thinking it would be good. I'll look again. I can't get NAG in Oz either, what a surprise <g>.
The problem with all of this is ..one can get away usually with importing up to US$25 amounts only..then one gets hit with customs..like over double the price, long delays, maybe even lost or rejected etc...and postage from iherb is $40US <g> each order...so if nothing else that limits one. Most companies won't even sell to Oz due to customs. (whine<g>)

http://www.caramal.com/ltyg/readqa.asp?ReferralName=accaq&ReferralURL=I'm a bit confused as to the link between glutamine and glucosamine? I had a quick look and couldn't see it.
Although it sounds just what I need to..especially considering did try cutting back on drinking as advised by endo, and I just craved carbs..like chocy, lollies, a whole sponge cake..and I used to eat healthy too..
Carbs retain water I think? or is it they don't require as much water to metabolise?. Not sure but I do know the weight loss for the first couple of days on a low carb diet is mostly water loss.My mouth saliva tastes extremely salty,
my eyes sting like from salt..I was soo thirsty..and is still drank and voided way too much. Can't sleep at night from thirst,..I gave up after a few night and last night I drank water!!
Besides bladder stuff, apparently one's kidneys can't handle that volume of urine and will just pack it in as one gets older.
But yesterday I decided to drink more again..and
and today I'm just going to drink as much as I want!!!!! well maybe not THAT much, but I just can't do the staying thirsty thing any more..
I read yesterday that low adrenals can mask this problem..and I think my cortisol /adrenals are on the improve..not real low as before, just can't handle stress now.
My blood presure is increasing too ..probably adrenals kicking in (I hope)
http://patients.uptodate.com/topic.asp?file=fldlytes/6651&title=Adrenal+insufficiency
I've always been thirsty, but now its worse..very difficult to distract my mind from the thirst...Thanks Ray, your a great help
Actually I might go to a sauna and see if I can sweat some of this salt out and water too sometime

Hi Jan - meant to be decorating today and avoiding the computer...but couldn't resist looking up this link...
Austistic children have problems maintaining their sulphate levels, and so have problems detoxifying. They also have problems digesting because the hormone CCK needs sulphate to activate it. CCK is needed for the release of vasopressin and oxytocin.
Dose response of arginine vasopressin to the CCK-B agonist pentagastrin.
Abelson JL, Le Melledo J, Bichet DG.
University of Michigan Department of Psychiatry, Anxiety Disorders Program, Ann Arbor, MI, USA.
Cholecystokinin (CCK) is a peptide neurotransmitter that modulates hypothalamic-pituitary-adrenal (HPA) axis activity and may be involved in fear or anxiety states. Arginine vasopressin (AVP) also modulates HPA axis activity and may play a role in fear conditioning. Few human studies have examined interactions between CCK and AVP systems. To explore relationships between CCK-B receptor activation, the HPA axis response, and AVP release, a dose-response study using the CCK-B receptor agonist pentagastrin was conducted. Adrenocorticotropin (ACTH) and cortisol results have been previously reported and AVP data is presented here. Thirty-five healthy subjects were randomly assigned to receive placebo, or 0.2, 0.4, 0.6, or 0.8 microg/kg doses of pentagastrin. AVP release appeared to increase with increasing doses of the CCK-B agonist. However, this may have been due to a greater percentage of subjects releasing AVP in the higher dose groups, rather than a direct effect of dose on magnitude of response. AVP and ACTH responses were correlated, but AVP response alone could not account for the magnitude of the ACTH response. AVP release was significantly correlated with anxiety symptom responses. These findings suggest a possible role for the CCK-B receptor in AVP release, which may be at least partially separate from its role in modulation of the HPA axis. Further work is needed to determine whether these are physiologically meaningful interactions and to determine their functional implications

>Thanks Simus! I saw around 5 or 6 kinesiologists before I found one I was happy with. Kinesiology isn't a therapy itself, more a feedback tool to let the body give answers to questions asked of it (does sound flaky, sorry!). The reliabilty of it is only as good as the person asking the qestions - and is also reliant on the clarity of the patient's body about their condition. Some kinesiologists do use that finger test, but I would trust one finger test to give a supplement - it's too open to bias from the practitioner - it's very easy to will something to work.
The kinesiology I use requires arm, leg, skin pinch, tongue, neck, arm & leg length tests, eyes open and closed, before a supplement is given - the body is also given the chance to say 'i don't know' to any of these tests, as well as yes or no.
I really feel you need around an hour and a half for each session - personally, I've found it takes a lot of sessions to start to see a pattern developing.
Hope that wasn't too confusing!

Hi Ray,
Hope your decorating went well. and thanks for all your help, you've somehow come across the two things my body doesn't seem to handle normally probably, NO/nitrates/nitrites and sulphates/sulphites which is interesting, and I've come across CCK before too, although I've never looked at it ..and I'll need more time and probably a better brain to work it out. I'd read about aquaporins just b4 you mentioned them in that book I told you about "Review of Medical Physiology" by Ganong. There are 5 types apparently, one in the brain too..
I've been on uni study break for exams, so I figure I'd better start studying now as exams are next week..twas no use in the past week or so anyway as my memory wouldn't work for that long!(true<g>). I have good results so far..but I can't remember a thing..oh except osmosis and kidneys<g>
So I'm drinking again....do they have a waterholics anonymous(an AA equivalent)? I can't stop drinking..but I need to drink so I can concentrate and sleep.<g> I do understand that the lower blood pressure /higher plasma osmalility can stimulate ADH..but there has to be a limit to how high one can make one's plasma osmalality.
I'll go over your posts in more detail and attempt some replies after the exams.Thanks for helping, really appreciated,you throw up some interesting ideas,
Jan

Hi Jan, good luck with your studying - just came across this abstract that seemed to tie in a lot of the things you are talking about. Superoxide excess seems to be a common thread in inhibiting the vasodilation and sodium balance in the kidney. Nitric oxide turns from a vasodilator to a vasoconstrictor when it combines with superoxide to form peroxynitrite - you didn't say what you had at the dentist, but if it was nitrous oxide, it might have been able to form peroxynitrite too - nitrites in bacon can definitely produce peroxynitrite.
Just found out that sulfites can trigger NADPH oxidase, and produce superoxide - seems to fit the pattern quite well! NADPH is needed for glutathione formation (nitric oxide, dopa, serotonin, steroid hormone synthesis, noradrenaline and folate activation!), so to lose too much is disasterous.
If you think this relates to you, arginine might be beneficial, but healing the endothelium cells to allow proper vasodilation to occur (not forgetting dealing with superoxide). I've used Venocap by Thorne research to help my endothelial cells - it contains, witch hazel, horse chestnut, butchers broom, gotu cola, grape seed extract. Lar gave me a link to an article by Dr Pall on peroxynitrite on a recent thread.
Nitric oxide, oxidative stress, and progression of chronic renal failure.
Modlinger PS, Wilcox CS, Aslam S.
Division of Nephrology and Hypertension, Georgetown University Medical Center, Washington, DC 20007, USA.
Cellular injury or organ dysfunction from oxidative stress occurs when reactive oxygen species (ROS) accumulate in excess of the host defense mechanisms. The deleterious effect of ROS occurs from 2 principal actions. First, ROS can inactivate mitochondrial enzymes, damage DNA, or lead to apoptosis or cellular hypertrophy. Second, nitric oxide (NO), which is a principal endothelial-derived relaxing factor, reacts with superoxide anion (O2-) to yield peroxynitrite (ONOO-), which is a powerful oxidant and nitrosating agent. The inactivation of NO by O2- creates NO deficiency. Oxidative stress can promote the production of vasoconstrictor molecules and primary salt retention by the kidney. Several hypertensive animal models showed increased activity of nicotine adenine dinucleotide phosphate (NADPH) oxidase, which is the chief source of O2- in the vessel wall and kidneys. NO regulates renal blood flow, tubuloglomerular feedback (TGF), and pressure natriuresis. Animal models of NO deficiency develop hypertension, proteinuria, and glomerulosclerosis. Evidence is presented that chronic renal failure (CRF) is a state of NO deficiency secondary to decreased kidney NO production and/or increased bioinactivation of NO by O2-. Patients with CRF show decreased endothelium-dependent vasodilatation to acetylcholine, have increased markers of oxidative stress, and diminished antioxidant activity. Therapy for oxidative stress has focused on antioxidants and agents that modify the renin-angiotensin system. The effects of such treatments are more compelling in animal models than in human studies.

Hi again Jan! thanks for that info - do you think the catecholamines are included in that two way thing too? Phenylalanine to tyrosine - as phenylalanine is an essential amino acid and we must get it from the diet I'm not so sure. DOPA decarboxylase to dopamine, would need a carboxylase enzyme to work the other way. Do you think there is some reverse flow traffic?

any carboydrate, fat or protein can in theory metabolise to glutamate as glutamate is a by product of the energy cycle - glutamine is one step, other chemicals are several more steps - sorry not to give a straight answer!

Thanks, Ray. By the way, you say "a supplement is given". How is it given? I assume that you don't ingest it, or you could only do one test a day. So do you put it under your tongue, hold it against your skin...?

If you click on the ovals you get pathways say for tyrosine metabolism.I guess you can see where some paths are bidirectional.
(doesn't look more difficult than something out of a car manual)Maybe some only go one way..as far as the enzymes go, but then if you alter he concentration gradients it should encourage alternative pathways of metabolism. Maybe that is the effect I see, taking one thing would maybe in theory at least encourage buildup in previous substrates?(not sure of right word)..but that would give an appearance of backwards flow.
Doesn't appear to have inhibitors on these pathways though which are just as important.

OK I found it I think..top line of this
http://www.genome.jp/kegg/pathway/map/map00251.htmlso that kinda has something to do with G6PD(or something close) I think?

OK I looked up what is needed maybe in the pathways
http://www.genome.jp/kegg/pathway/map/map00140.html
"AND CLICKING on 1.14.15.6
Oxidoreductases
Acting on paired donors with incorporation of molecular oxygen
With a reduced iron-sulfur protein as one donor, and incorporation
of one atom of oxygen"so as well oxygen maybe I need iron-sulfur...there's that sulfur again!!!! (and iron)
OK so for sulfur I need TMG, NAC, NAG ??
I guess something like magnesium sulfate is different?? I have epsom salt baths but they always make me very tired after..actually usually drift in and out of sleep in the bath. Note sure if that's the sulfates or just the relaxation.
Lar mentioned sulfur stuff to me last year too re thyroid hormones.Another cholesterol path
http://www.genome.jp/kegg/pathway/map/map00120.html
needs that NADPH again and oxygen
"With NADH or NADPH as one donor, and incorporation of one atom of
oxygen"
I thought that CoQ10 (ubiquinone) should be somewhere around cholesterol too? as the drugs that inhibit cholesterol synthesis also stop CoQ10 synthesis? But I can't find the link there.Jan

(and iron)Oxygen is the second most reactive element of them all....more so than is chlorine (from electronegativity standpoint). Fire is an uncontrolled oxygenation chain reaction. Currently, the atmosphere contains about 17% oxygen. If it got up to 22%, it would be impossible to put out fires with water (itself burned hydrogen), as the exothermic reactions would not be cooled enough by the heat absorption capacity of water (specific heat), and the latent heat of vapourization.
The point is, our bodies work only because Mother Nature has learned how to slow fire down, to control it somewhat. Sulphur loves oxygen. Oxidative stress depletes sulphur compounds in the body.
> OK so for sulfur I need TMG, NAC, NAG ??
TMG remethylates one particular sulphur compound, homocysteine, but it is not a source of sulphur.
Common sulphur sources are methionine, SAMe, cysteine, taurine, creatine (a tripeptide with methionine). NAC is N-acetyl-cysteine, so it is a source. MSM too.
> I guess something like magnesium sulfate is different?? I have epsom salt baths but they always make me very tired after..actually usually drift in and out of sleep in the bath. Note sure if that's the sulfates or just the relaxation.
More likely the magnesium. It is taken in transcutaneously, though only slightly. Sulphates are not a good metabolic source of sulphur, as they're already fully oxidized (SO4--).

> Yes that sounds a good idea, although I seem to be doing amazingly well just upregulating the enzymes. Have you heard about the kynurenine pathway that breaks down tryptophan to niacin?I really doubt that significant amounts of tryptophan are shunted via this pathway. There are substantial opportunities for negative feedback (inhibition).
> Tryptophan metabolites at the start of the pathway seem to be neuroprotective, but as the pathway nears niacin, metabolites like quinolinic acid are highly neurotoxic - seems like niacin/naicinamide can provide negative feedback to this pathway.
Without doubt, they do.
> >Methinks that one of my own responsivities to supps, that of Enada NADH, is that it may not only re-energize my ailing mitochondria, but it may also give my H2B --> H4B recycling a major boost. If so, then neurotransmitter precursor loading with NADH might be an effective augment. Experiment requires purchase of supps, though.
>
> I seem to do better on niacinamide rather than NADH - if fact I feel very little with NADH, which is surprising considering how important it is to the pathways we've been discussing. I'm guessing that maybe I need the large dose of niacinamide to inhibit the parp molecule I mentioned before. Parp seems to be involved in the pathogenesis of many diseases - for example this abstract finds that inhibiting parp can stop homocysteine induced blood vessel damage.Thanks for bringing PARP back to my attention. I need reminders of why I use my supps.....absent-minded professor type. I often don't remember what I need to remember for self-care, until someone triggers me to think about it again.
This abstract is quite on point:

One part of the book mentions an enzyme called DPP IV (available as a supplement from kirkman labs), involved in regulation of the immune and nervous system, and particularly helpful in autoimmunity and depression. Apparently mercury, gluten from wheat and casein from milk can bind DPP IV and trigger brain fog, inflammation and depression.

> Tyrosine is also the precursor to T4 and T3, T4 has four iodines added, and T3 has four added and one taken away. So I wonder if the tyrosine gives your thyroid a boost...heres a bit about thyroid and pain threshold..

Some of the cells, mainly in her spinal cord, when under-regulated by thyroid hormone, release excess amounts of "substance P." The excess substance P then amplifies the transmission of "pain" impulses in the central nervous system."
I've only ever seen models based on NMDA amplification. I have hyperalgesia and allodynia, but not disturbed thyroid function (at least, not diagnosed). Hyperalgesia and allodynia are often linked with chronic fatigue syndrome and PTSD. This is thought-provoking.

> > One simple test of adrenal stress is to try some licorice. Do not use DGL, though. That is De-Glycyrrhizinated Licorice.I hope you're still around to see this answer.
Licorice root has the effect of creating an illusion that the adrenal output is higher than it really is. It does so by increasing the half-life of cortisol. This could have two possible observable effects, if adrenal output was bad before the licorice. If adrenal output is unstable or fluctuating (what some call sputtering), licorice will stabilize both mood and energy somewhat. If adrenal output was stable but low, the energy and mood will gradually improve. If licorice makes you feel wired, jumpy, or anxious, then it's likely that there wasn't a problem with the adrenals to begin with. It takes a good four to six weeks of licorice use to determine the outcome.
> What would be the "something" that would be noticeable when taking licorice that would indicate the adrenal stress?
See above.

Also feeling very "disconnected" at the moment too and extremely short tempered and irritable.Could be the ginkgo. Also, taking B6 without other B's is not a good idea. Get a B complex, and take it in addition to the B6, or instead of it altogether. You might find that additional niacinamide smoothes you out a bit.
