Treat the Patient. Not the SNPs
Why?
Key Points about SNPs and Clinical Use •! Most SNPs not clinically relevant •! Optimizing pregnancy •! Increases compliance •! Fantastic for disease prevention •! Ability to optimize patient’s wellness •! Identify possible nutrient deficiencies •! Identify predispositions and risks •! Contributing cause towards patient signs/symptoms •! Ability to create a long-term plan •! Forces a need to understand the normal function and interactions. •! Identify reasons why patient responds poorly/favorably to treatment.

Ascorbic Acid: Its Importance and the Glucose Ascorbate Antagonism 3/28/14! Theory John Thoreson
The Primary Mantra!
Ascorbic Acid:" Its Fundamental Importance …" The Glucose Ascorbate Antagonism Theory"
•! “The rate limiting factor of immune system
From work by John T A Ely, PhD, Col US Air Force ret.!
function is intracellular ascorbate.”!
•! If true, this is a most basic underlying principle for maintaining and restoring health … especially in the face of our mutation!!
43rd Annual Orthomolecular Medicine Today! 25 April 2014!
•! Underlying corollary to the mantra is the Glucose Ascorbate Antagonism Theory (GAA)!
Presented by! John Thoreson, BA!
Key to the corollary GAA!
The Key to the Mantra! •! •! •! •!
In a normal human leukocyte the intracellular levels of AA are maintained via an insulin mediated active transport system at nearly 50 times the surrounding serum levels! When needed (i.e. stress, disease, trauma, etc.) the rate of synthesis of converting glucose into AA – in all mammals not mutated (like humans) – increases 10 to 100 times!
•!
This increased amount of AA in circulation now via this uptake pathway results in an elevation in the intracellular levels of AA and a significant increase in immune system function and integrity!
•!
Intracellular ascorbate is monotonically related to driving the HMP shunt – to produce ribose (among other things) needed to make rna when rapid mitosis, high rate of metabolic activity and synthesis are needed!
The GAA is critical as when glucose levels are even modestly elevated over normal, given its ancient sisterhood with AA, glucose will outcompete AA for uptake into the leukocytes! Leaving the immune system unable to adequately rally to the challenges presented!
A Brief History of Discovery!
It is as simple as …!
Cosmic Rays & Human Health: In the 1970’s Ely proposed a latitudinal relationship between cosmic radiation and human cancers (low latitude low incidence – & vice versa)! The further from the equator the greater the mutagenic effect of background cosmic radiation!
Nothing is as easy or simple as we would wish it to be,! yet if we had to know it make it work?!

Ely’s work bench in the design phase of his Cosmic Ray Detector For Satellite !
A bit of context and perspective: The Solar System!
High-energy Cosmic Ray Experiment as Part of this Satellite!
Energies Required for Cosmic Ray Secondaries to Reach the Earth s Surface!
Green = 15 GeV
The trouble with Theories! •! •! •! •! •!
Red = 0.12 GeV!
For Instance:" Sugar Intake and Breast Cancer Death Rates!
There were anomalies in the cancer data – very disturbing for a physicist (data supported theory pretty much … yet anomalies violated his expectation)! Mid-latitude countries with higher than predicted cancer rates! From WHO data - high sugar consumption in these countries! What does sugar have to do with Cancer? ! Non-mutated mammals able to convert glucose into ascorbate (… then what does ascorbate have to do with cancer?) From this and other papers published on leukocytes in the 1970’s he deduced the GAA … and hence the primary mantra!

Porphine!
CO2 and H2O – Totally Oxidized! Nature at its conservative best – the magic of the porphyrin ring! Reduces, Restores – reload these spent atoms/molecules with sunlight energy! Oxidized C & Oxidized H become CHO … sugar … YEAA SUGAR!!!!
Production of Glucose By Photosynthesis in Plants Leads to Ascorbic Acid!
Ascorbic Acid!
Production of Ascorbic Acid in Plants and Mammals!
Galactose!
Adapted from: Nutritional Sciences: From Fundamentals to Food#By Michelle McGuire, Kathy Beerman (2012) !
There will be consequences!
Biosynthesis of Ascorbic Acid in Rat Liver!
•! •! •! Derived from Kustermann, et al., 1998!
•!
To our benefit and loss, alas we are mutated.! “Solution has its problems” JTA Ely!
•!
Our liver enzyme L-gluonolactone oxidase isn’t so active! Leukocytes require high AA levels to drive the HMS to supply adequate H2O2 and ribose for effective phagocytosis and mitosis! In even modest BG elevations (over 130 mg/dL) BG so outnumber AA as to competitively inhibit insulin-mediated active transport of AA into cells – resulting in low intracellular levels, low HMS, cell dysfunction, etc – this is the glucose ‘antagonism’ of AA! The GAA theory gives rise naturally to Aggressive Glycemic Control diet and concurrent supplementation with AA! Ignore this at our own peril … leading to untold morbidity, mortality, great cost, and suffering.!

Car Story:!
Aging: Predictions of a New Perspective on Old Data" Society for Experimental Biology and Medicine: 2002 pg.939-942 Ely, Krone !
Ely related to Pauling in 1973 this theoretical reason why the clinical trials of vitamin C against colds and cancer may have failed because the high blood sugar in the affluent nations.!
•! Compared our 4,000 mammal relatives ratio of Life Expectancy to Age of First Estrus: R = LE/AFE!
•! Most relatives have an R value of ~25! •! Humans … 8! •! Can we live better longer? We shall C!!
My mission in May of 1990: If this is true, and the answer so basic and reasonable – why does it remain so unacted upon?! Change, although stressful can be good!
John Ely worked relentlessly throughout his life to solve the problems of our shared human dilemma. A fundamental appreciation of the role of Ascorbate in health & immune integrity is just one of his contributions. ! Thank you all for being here.!

5**(:;&2(%7<;+%7===( •! Promotes fat storage and stops you breaking down fat, so you gain more and more weight. Increases non-alcoholic fatty liver. •! Increases cholesterol and triglycerides (blood fats) •! It causes the kidneys to retain both water and salt, which leads to high blood pressure. In time this leads to kidney failure •! Causes rapid deterioration of eyesight •! The combination of too much insulin and to much glucose damages the arteries and raises your blood pressure, both of which make thrombosis, heart attacks and strokes more likely •! Makes cancer cells grow fast mainly due to increased insulinlike growth factor (IGF-1) •! Switches off anti-ageing genes (DAF on, FOXO off)

Older women need their hormones too
Sad Women •! Hot Flashes, anxiety, and panic attacks are hormone deficiency symptoms, relieved with bioidentical hormones. SSRI anti-depressants do not contain estrogen, and their use for estrogen deficiency is an abuse and victimization of women who suffer from estrogen deficiency. •! SSRI drugs should not be used to treat estrogen deficiency symptoms.
Dr. Bronson's book could not have been published at a better time. Brisdelle, a version of Paxil or paroxetine, has just been approved by the FDA as a treatment for hot flashes, despite an advisory committee vote of 10-4 against it.

What is the Mechanism of Action of Estrogen in Eliminating Anxiety and Depression?
NO on saliva tests because Gender hormones enter portal blood 3 ways
•! Estrogen receptors have been found in the brain, and estrogen increases the expression of an enzyme in the brain called tryptophan hydroxylase-2 (TPH2).
1. Free 2. Loosely bound to Albumin 3. Tightly bound to SHBG
•! This enzyme s job is to convert tryptophan to serotonin, an important neurotransmitter responsible for anti-anxiety and calming effect in the brain.
All are available to dock at receptors if bioidentical
JDach
Estriol is safe
Recent Research !!
The female uses both weakly bound and free forms of these hormones at receptors. Saliva tests only measure the free, unbound portion of the hormone molecule in serum, so they don t give a complete picture of the available potentially active, or bioavailable, hormone.

The Moods of Aging: Hormones and the Mind-Body Connection3/25/14 Phyllis Bronson, PhD Stability of estrogens The electrode potential of the estrogens do not necessarily reflect their thermodynamic relationship to one another. The electrode reactions as measured are irreversible, that is kinetically controlled. The current voltage curves which they yield do not necessarily reflect their oxidation/reduction characteristics in physiological systems.
As to the effectiveness of bioidentical hormone therapy, this was established in a recent study by the University of Texas Health Science Center. The researchers followed 296 women who received bioidentical hormone therapy between 2003 and 2010.
Two doctors from the Cleveland Clinic, one of which has represented pharmaceutical companies that manufacture synthetic hormones, recently published a paper that lambasts any perceived benefits of bioidentical hormones.
The study found that the women overall experienced a 25% reduction in emotional mood swings and irritability, 22% less anxiety, and a 14% reduction of night sweats.
The paper, published in December s Cleveland Clinic Journal, states that there is no evidence that bioidentical hormones provide aging benefits, reduce side effects, or present a legitimate option to FDA approved pharmaceutical synthetic hormones.
The researchers concluded that, This study demonstrates that compounded bioidentical hormone replacement therapy improves mood symptoms.
4) Estriol acts differently in the body from esradiol, estrone, and equine hormones. Thus estriol would be expected to carry less risk for breast cancer, stated the paper.
A 2009 review of clinical evidence by Kent Holtorf, MD, found that:
1)! Patients report greater satisfaction with Hormone
5) Progestins from pharmaceutical hormones come with a variety of negative cardiovascular effects, which may be avoided with progesterone.
replacement therapies that contain progesterone compared with those that contain a synthetic progestin.
2)!Bioidentical hormones have different molecular structures and significantly different metabolic effects from synthetic versions.
Dr. Holtorf s paper concluded that bioidentical hormones are linked with reduced risks of breast cancer and heart disease, and are more efficacious than their synthetic and animal-derived counterparts.
3)!Clinical research and physiological data has found
progesterone not to have the risk for breast cancer associated with synthetic progestins.

Distort the evidence: Cirigliano tries to defend Premarin by saying another pharmaceutical Enjuvia, is synthesized to mimic Premarin for relief of vaso-motor symptoms Pharmawrite concludes that this drug is obtained from plant sources and mimics Premarin- this is not the issue with determining bioidentical status
Opposing Effects
News? Newsweek is an Infomercial
Synthetic progestins may also increase the conversion of weaker endogenous estrogens into more potent estrogens, potentially contributing to their carcinogenic effects, which are not apparent with progesterone.
Masquerading as Medical News

Estrogen is most important for cognition, but progesterone also serves the brain, decreasing anxiety and mood swings.
Oral Progesterone such as Prometrium or compounded goes through liver first pass, and after being metabolized affects GABA receptors in a more potent BDZ drug like manner.
Progesterone enhances dendritic activity, so that neuroinhibitory molecules are more readily up-regulated. Natural Progesterone from your ovaries or transdermally applied in sufficient quantity affects GABAA and GABAC receptors.
5-alpha pregnandione is made in upper GI from oral progesterone: this has 12x the potency of Phenobarbital

Travel to mineral springs dates back ~ 2000 years
•! Lithium is highly anodic in the galvanic series •! Reacts with water something like sodium does •! Not very stable, but excellent energy density •! Joules of energy per kilogram •! Offers electronics that are smaller, lighter, thinner
Gerhard Schrauzer Born in Eastern Europe, grew up interested in the local mineral springs purported by locals to having moodenhancing properties. German: ‘Natalie Quelle’
•! Widely used battery technology in small electronics

Li is an Essential Nutrient •! Every cell contains lithium.
•! The body does not synthesize it’s own lithium.
•! Must be exogenously supplied: physiologically essential •! Required dose is estimated to be ~ 1 mg/ d.
LITHIUM SCIENCE
Conditional essentiality has yet to be determined: Are there certain populations who may have unique requirements?
Likely, given what we know about biochemical individuality, SNPs, epigenetics, etc.
Is it essential? What are the symptoms of deficiency? How is adequacy assessed?
Schrauzer GN. J Am Coll Nutr 2002;21(1):14-21.
Where does it come from ?
Human Intake
•! WATER •! A function of the natural variation in the Earth’s crust •! The higher the rainfall in any region, the lower the lithium level in the water supply.
•! Average US consumption: 650- 3100 µg/d.
Determined by location/ source of water Soil/ mineral content of diet
•! FOOD •! Likely a function of the soil the foods were grown in, and how well they are washed before consumed. •! Last analyzed 20+ years ago- farming practices have changed substantially.

Regulation of autophagy
Glycogen synthase kinase-3 beta
Autophagy is the process by which cell lysosomes engulf and digest our used and dysfunctional waste, and recycle it into component parts, e.g. amino acids. (Greek, auto “self” and phagein “to eat”)
GSK3b is involved in energy production & neurogenesis. 2 mechanisms by which Li inhibits GSK3b: •! Li dislocates Mg binding to the catalytic core of GSK3b •! Li induces conformational change via phophorylation of the serine-9 residue, rendering it inactive.
Dysregulated autophagy is a major problem in all of the neurodegenerative diseases. •! In Caenorhabditis elegans, lithium supplementation resulted in
increase in healthspan and mitochondrial energetic function.

Dementia & Alzheimer’s The Facts
Patrick Holford Food for the Brain Foundation
•! Three in ten over age 70 have impaired memory, 80% of which will develop dementia within 5 years (2/3rd is Alzheimer’s).
•!
The cause and prevention of Alzheimer’s dementia
550 people (over 6 double decker buses worth) are diagnosed with dementia every day in the UK. (Matthews,PLoSMed,2005)
•! 44 million worldwide have dementia and is expected to double every 20 years to 135 million by 2020.(ADI, 2014)
•!
The current cost is $604 billion a year - 1% of GDP. (ADI, 2014)

•! Alzheimer’s Disease (AD) is characterised by a progressive loss of cognitive functions including memory, language, judgment, praxis and orientation and is diagnosed on the basis of shrinking in the thickness of the Medial Temporal Lobe, which is considered to be the primary pathology that generates the associated symptoms. •! The detectable, preclinical phase of AD presents as Mild Cognitive Impairment (MCI).

P- Tau and Amyloid-B proteins
All phase 3 drug trials have failed
Sontag E et al., Journal of Neuroscience, 27(11):2751–9 (2007).
#! In AD there are neurofibrillary tangles, and an increasing
deposition of amyloid-B proteins. However, research with drugs aiming to reduce formation of amyloid-B proteins has been singularly unsuccessful, possibly indicating that this hypothesis is wrong.
#! Recently, research has identified P-tau proteins which leads to the build up of these neurofibrillary tangles, which is one of the hallmarks of Alzheimer’s.
#! But is this the cause or the consequence? Homocysteine is high in the sites of decay. It is, itself, capable of damaging neurons. When there is an increase in P-tau there is a corresponding increase in homocysteine.

The drugs don’t work
Do genes cause Alzheimer’s? #! Bekris L, J.Ger.Psych 2010; Heininger K, Human Psychopharm 2000; Ridge P, PLoS1 2013
•! In a five-year trial of Aricept there was no difference in ‘worthwhile improvements’ in a range of categories: rates of disease progression, the rate at which patients were placed in nursing homes, caregiver time, or how fast behaviour deteriorated, regardless of the dose given. The one benefit is that during the first two years of the study, those on Aricept did slightly better in tests measuring thinking and functional ability. (Lancet 2004) •! In a study of 224 people with Alzheimer’s those who were taking antipsychotic drugs or sedatives had an almost three-fold higher risk of deterioration than those who were taking none. Even worse, for those taking both antipsychotic and sedative drugs together, their risk of deterioration was almost quadrupled. (J Neurol Neurosurg Psychiatry 2007) •! Drugs aimed to reduce amyloid-B synthesis have repeatedly failed. (Lancet, 2010)
#! Three causative genes (APP, PSEN1, PSEN2) account for less than 1% of cases of AD.
#! Other genes predispose, but don’t cause. For example, having the ApoE4 gene, if expressed, may account for 4% of the inheritability of risk.
#! 11 other genes may account for 7.8% of the inheritability of AD.
#! Gene studies suggest that, in total, genes could account for a third of one’s inherited risk or predisposition. In other words, if you had all the wrong genes you would be 30% more likely to get AD.
Best evidenced non-genetic risk factors

#! David Smith et al, Journal of Alzheimer’s Disease 38 (2014) 699–703 We estimate that about half of Alzheimer’s disease cases worldwide might be attributable to known risk factors. Taking immediate action on the known risk factors could perhaps prevent up to one-fifth of predicted new cases by 2025.

There is already sufficient evidence to justify immediate action. Trials in those at risk of developing dementia should be done of the following: exercise; controlling blood sugar, including diabetes treatment; depression treatment; high blood pressure treatment; B vitamins; omega-3 fatty acids; cognitive training; and social activities.

How high Hcy can raise amyloid and tau
Life style/age eg stress, smoking
•! High Hcy leads to inhibition of methylation reactions because high Hcy leads to high SAH, which is an inhibitor of methyltransferases. •! DNA methylation controls the expression of presenilin so inhibition of DNA methylation leads to higher production of presenilin and so to more beta-amyloid production. •! Phosporylated tau is in a dynamic state, constantly being dephosporylated and re-phosphorylated. The enzyme that removes the key phosphate groups is called protein phosphatase 2A (PP2A) and this is activated by methylation. So, if methylation is inhibited, the activity of PP2A is reduced and P-tau builds up, so favouring the formation of neurofibrillary tangles.

Two reviews confirm Hcy/AD association
Folic acid improves memory in the elderly

Durga et al, Lancet. 2007, 369(9557):208-16
#! Both high homocysteine (Hcy) levels, and low folic and B12 levels in blood correlate with increasing risk for AD according to a systematic review. Another review, in 2008, concludes that of ‘Seventy seven crosssectional studies on more than 34,000 subjects and 33 prospective studies on more than 12,000 subjects have shown associations between cognitive deficit or dementia and homocysteine and/or B vitamins’.
A study conducted by Jane Durga, at Wageningen University in Holland, gave 818 people, aged 50 to 75 with Hcy >13mmol/l, either a vitamin containing 800mcg of folic acid a day, or a dummy pill. That’s almost three times the RDA and the equivalent of 2.5 pounds of strawberries a day – more than you can reasonably eat. Three years later, different aspects of intelligence were measured. On memory tests,the supplement users had scores comparable to people 5.5 years younger. On tests of cognitive speed, the folic acid helped users perform as well as people 1.9 years younger.
#! Hcy levels also predict and correlate with rate of cognitive decline, as does B12 status.
#! There is, therefore, ample evidence to propose that lowering homocysteine by giving appropriate supplemental levels of homocysteine lowering nutrients would reduce risk.
B12 lack linked to brain shrinkage
B vitamins stop decline in mild AD

homocysteine-lowering B vitamins to those already diagnosed as suffering from mild to moderate Alzheimer’s. Patients were not selected on the basis of Hcy values (average Hcy was 9.1mmol/l at baseline), and brain scans were not conducted. The patients received folic acid (5mg/d), B12(1mg/d), and B6 (25mg/d over a period of 18 months. No overall difference occurred in rate of cognitive decline in those on the supplements versus placebo. However, those who had milder Alzheimer’s taking the B vitamins had no decline in memory over 15 months, while those on the placebo showed a steady decline. The average drop in homocysteine over the 18 months was from 9.1 to 6.8$mol/ l.
insufficient B12 to prevent accelarated brain shrinkage and may suffer memory loss as a result. The study from Oxford University found that B12 deficiency was associated with brain shrinkage, a hallmark of dementia risk. B12, which is only found in animal products, becomes increasingly hard to absorb. 40% of people in this study, aged 61 to 87, had insufficient B12.

Slowing of atrophy depends on baseline Hcy
B12 & folic acid help AD with high Hcy

#! Kwok T, Clinical Nutrition, 2011
#! An RCT giving 140 people with mild to moderate AD or vascular
dementia 1mg B12 and 5mg of folic acid versus placebo found no difference overall, but in those with raised Hcy (above 13µM) at baseline, there was no decline in the primary outcome, the Mattis Dementia Rating Scale (MDRS) compared to 2 point decline in the placebo group (construction domain). This was a significant difference (p=0.003).

Outcomes of the VITACOG trials #! Smith AD, PLoS ONE 2010; de Jager C, Int. J.Ger. Psychiatry 2012;Douaud, PNAS, 2013
•! B vitamin treatment slows brain atrophy in Mild Cognitive Impairment by up to 53%, with the main area of the brain protected being the ‘Alzheimer’s’ area. •! B vitamin treatment almost stops further memory loss in those with high homocysteine. •! The slower the rate of atrophy, the slower the decline in cognitive abilities. •! The effect is greatest in those with a high baseline level of homocysteine. An effect is seen in those with homocysteine above 9.5µmol/l. •! High homocysteine levels are found in ~75% of elderly

7 Ways to Lower Your ‘H’ Score
Coffee is Bad News for Hcy Grubben M, AmJClinNutr, 2000; Verhoef P, AmJClinNutr, 2002; Ulvik A, Clin Chem 2008
1.! Eat more greens, seeds, nuts and beans, high in folate 2.! Eat more fish and eggs,high in B12 and methyl nutrients 3.! Cut back on coffee 4.! Limit alcohol 5.! Reduce stress 6.! Stop smoking 7.! Supplement homocysteine lowering nutrients daily
#! A study at the University Hospital Nijmegen assigned volunteers to drink a litre of unfiltered coffee a day – approx. four cups – for two weeks. At the start of the two weeks their average H score was 12.8 µM. At the end of the two weeks their H score was 14.
#! A study by Dr Verhoef and co. at the Wageningen Centre for Food
Sciences in the Netherlands showed that two cups of regular coffee increased homocysteine by 11% after only four hours, while caffeine tablets without coffee increased it by 5%.
#! A study of 10,601 Norwegians found that four cups of coffee a day vs none had 6.8% higher homocysteine and lower B vitamins 11.7% lower folate, 14.1% lower B6, 5.5% lower B2.

They followed 815 people, aged 65 to 94 years, for 7 years and found that the dietary intake of fish was strongly linked to AD risk.
