What is Nitric Oxide?
The chemical compound nitric oxide is a gas with chemical formula NO٠.
It is one of the most important signaling molecule in the body of mammals including humans, one of the few gaseous signaling molecules known.
It is also a toxic air pollutant produced by automobile engines and power plants.
NO should not be confused with nitrous oxide (N2O), a general anesthetic, or with nitrogen dioxide(NO2) which is another poisonous air pollutant.
The nitric oxide molecule is a free radical, which is relevant to understanding its high reactivity. It reacts with the oxygen in air to form nitrogen dioxide, signaled by the appearance of the reddish-brown color.

Nitroglycerine, a 100 year old explosive and heart medicine
In atherosclerosis, plaques reduce blood flow in the arteries. This decreases oxygen supply to the heart muscle causing chest pain (angina pectoris) and sometimes even myocardial infarction. Treatment with nitroglycerine provides NO, dilates the vessels, and increases blood flow. Thanks to the 1998 Nobel Laureates we now understand how nitroglycerine, an important heart medicine, works. It acts as a NO donor, causes dilation of the blood vessels, increases oxygen supply and protects the heart from damage and cell death.

Current Paradigm
Despite almost 30 years of research after its discovery, very few clinical drugs on the market for NO.- organic nitrates (used for over 150 years for treatment of angina)- inhalative NO therapy for neonates- phosphodiesterase inhibitors such as sildenafil (Viagra) which act downstream from NO
L-Arginine supplementation is ineffective and in fact detrimental in some populations
L-arginine therapy in acute myocardial infarction: the Vascular Interaction With Age in Myocardial Infarction (VINTAGE MI) randomized clinical trial. (JAMA. 2006 Jan 4;295(1):58-64)CONCLUSIONS: L-arginine, when added to standard postinfarction therapies, does not improve vascular stiffness measurements or ejection fraction and may be associated with higher postinfarction mortality. L-arginine should not be recommended following acute myocardial infarction.
L-Arginine ParadoxKm for NOS is 5µM. Plasma levels of L-arginine ~100µMHow can you get modest improvement in NO output when enzyme theoretically saturated withsubstrate?
Physiological systems are fraught with redundancy. Where is the redundant NO pathway? Why does such a critical molecule only have a singular complex and complicated pathway to production????
Reduced NO availability is a hallmark of a number of cardiovascular disorders.
- Endothelial dysfunction is a physiological dysfunction of normal biochemicalprocesses carried out by the endothelium, the cells that line the inner surface of all blood vessels including arteries and veins (as well as the innermost lining of the heart and lymphatics).
- Loss of endothelial NO function is associated with several cardiovascular disorders,including atherosclerosis, which is due either to decreased production or to increaseddegradation of NO (Davignon and Ganz 2004).
- Experimental and clinical studies provide evidence that defects of endothelial NO function, referred to as endothelial dysfunction, is not only associated with all major cardiovascular risk factors, such as hyperlipidemia, diabetes, hypertension, smoking and severity of atherosclerosis, but also has a profound predictive value for the future atherosclerotic disease progression (Schachinger, Britten et al. 2000; Halcox, Schenke et al. 2002; Bugiardini, Manfrini et al. 2004; Lerman and Zeiher 2005).
- The dysfunctional eNOS/NO pathway is considered as an early marker or a common mechanism for various cardiovascular disorders. Over the last two decades, it has become evident that decreased bioavailability of endothelial NO, produced from endothelial NO synthase (eNOS), plays a crucial role in the development and progression of atherosclerosis.
Cardiovascular disease (CVD) is the number one killer of both men and women in the U.S. Close to 1 million people die each year and more than 6 million are hospitalized due to CVD. The cost of CVD, in terms of health care and lost productivity, is over $270 billion and increasing as the baby boom population ages.
Ischemic heart disease, including myocardial infarction, remains the leading cause of morbidity and mortality in all industrialized nations
What is the physiological consequence of enhanced NO productionin Ischemia-reperfusion injury?
Can we trace the phenotype biochemically?

Atmospheric Nitrogen CycleThe store of nitrogen found in the atmosphere, where it exists as a gas (mainly N2), plays an important role for life. Most plants can only take up nitrogen in two solid forms: ammonium ion (NH4+ ) and the nitrate ion (NO3- ). Most plants obtain the nitrogen they need as nitrate from the soil. When released, most of the ammonium is often chemically altered by a specific type of bacteria (genus Nitrosomonas) into nitrite (NO2- ). Further modification by another type of bacteria (genus Nitrobacter) converts the nitrite to nitrate. All nitrogen obtained by animals can be traced back to the eating of plants at some stage of the food chain.
Dietary nitrate is rapidly absorbed into the bloodstream, where it mixeswith endogenous nitrate from the NOS/NO pathway. A large portion of nitrate is taken up by the salivary glands, secreted with saliva and reduced to nitrite by symbiotic bacteria in the oral cavity. Salivary-derived nitrite is further reduced to NO and otherbiologically active nitrogen oxides in the acidic stomach. Remaining nitrite is rapidly absorbed and accumulates in tissues, where it serves to regulate cellular functions via reduction to NO or possibly by direct reactions with protein and lipids. NO and nitrite areultimately oxidized to nitrate, which
again enters the enterosalivary circulation or is excreted in urine.

Traditional Chinese Medicine
Traditional Chinese Medicine (TCM) has been used as a main stream of
medical care throughout Asia for centuries. But it is still considered an
alternative medical system in the western world. Mostly because of a lack of
understanding of their mechanisms of action and/or the active compounds.
Many cardiovascular diseases are characterized by a NO insufficiency.
There are a number of published reports on the association of TCM and NO-
related effects in cardiovascular field. However, their mechanism of action is
far from clear.

Ideal Community:
� Higher Nitrate reduction efficacy
� No NiR enzyme; Nitrite can accumulate,
enrich saliva to form NO when swallowed.
Tongue Scrapings Reveal Different Nitrate Reductase Activity in Culture
The microbial community structure changes as nitrate reduction decreases. Unweighted UniFrac-based Principal Coordinate Analysis (PCoA) illustrates the first two principal coordinates (PCs) for inocula, best reduction, intermediate reduction, and worst reduction groups. Unweighted UniFrac is a phylogenetic-tree based method that determines the similarity of two microbial communities based on the amount of shared branch length; thus, similar communities cluster closely on PCoA. Each dot represents a single sample and the amount of variance explained by each PC is indicated in parenthesis next to each axis.
NEW PARADIGM FOR NO REGULATION
- There exists specific bacterial communities that provide the human body with continuous sources of nitrite and NO from dietary nitrate.
- Contributes to optimal cardiovascular health
- Absence of these oral bacterial communities affects NO homeostasis.
- Individuals deficient in these commensal bacteria would be NO deficient and perhaps at increased risk for cardiovascular disease
Disruption of Nitrate-Nitrite-NO Pathway
1. Insufficient dietary intake of nitrate/nitrite rich foods(green leafy vegetables, beets, etc)
2. Problems with nitrate uptake in duodenum (sialin (SLC17A5) transporter mutations – Salla Disease)
3. Insufficient saliva production (Sjogrens syndrome)
4. Lack of oral commensal bacteria to reduce nitrate to nitrite (use of antibiotics/antiseptic mouthwash, poor oral hygeine)
5. Insufficient stomach acid production – Achlorhydria(use of PPI’s, H. Pylori infection, iron overload)
6. Increased oxidative stress that scavenges NO
What might this mean?
� Absence of these select bacteria - a new risk factor for cardiovascular disease.
� Patients with periodontal disease , affecting the NO producing communities - possibly linking oral health to cardiovascular disease risk by disruption of NO production
� Use of antiseptic mouthwash or overuse antibiotics can disrupt nitrate reducing communities
� Patients taking proton pump inhibitors to suppress stomach acid production
� Develop this pathway as a primary therapeutic target to affect NO production
Should we be concerned about our NO status how do we correct NO insufficiency?

Steady State NO in Dialysis Patients
High cardiovascular death rates for patients on hemodialysis remain a serious problem.
Cardiovascular mortality is considered the main cause of death in patients receiving dialysis and is 10 to 20 times higher in such patients than in the general population.
Expected remaining lifetimes for dialysis patients are only one-third to one-sixth those of the general U.S. population. For a healthy 20-year-old, life expectancy is around another 58 years – compared to 14 years in dialysis patients. A 50-year-old dialysis patient can expect another six years.
To date there is no molecular mechanism that has been shown to explain this increased mortality although nitric oxide has been implicated.

From: Bryan & Jamie Sent: Wednesday, August 03, 2011 9:52 PMTo:Subject: Jon
Just wanted to share something with you guys. Jon wanted to play chess tonight with Bryan. They have done this forever. Bryan has tried to teach him how to play over the years. He knows the pieces by name and what move that they can make but has never been able to comprehend the strategy needed to be successful. For instance, he has never understood how he needs to "protect" his pieces. Tonight he actually "foiled" Bryan's plays without Bryan's guidance. He thought through his plays, planned ahead and won the game. Bryan helped him but he truly came up with the plays himself and won the game.
Bryan asked him if he had been taking "smart pills" and Jon told him yes, the purple ones. I think he is right!

Heirarchy of Treatment Strategies
1. Recommend High NO Index Diet(use NO test strip 90 minutes after high NOmeal to determine if patient responds to nitrate load) – Beet Elite
2. Recommend Exercise Regimen(keeping below anaerobic threshold)
3. Include Neo40 supplement for all dental patients to support NO production and oral systemic health
Why is Neo superior technology?
1. Provides an exogenous source of NO2. Promotes endothelial production of NO3. Provides the body the nutrients
necessary for repairing endothelium4. Plant based natural product chemistry
(all-natural)5. No tolerance development6. Drug-like effects without side-effects7. Clear product experience8. Patented (3 patents issued - 5 pending)
CONCLUSIONS
There are profound effects of NO on health and disease
Recognizing NO insufficiency is critical for prevention of disease
L-arginine therapy is ineffective at restoring NO production in the older patients or patients with endothelial dysfunction
Enhancing NO production in the oral cavity combats pathogenic bacteria, suppresses inflammation and supports cardiovascular integrity
Include Neo40 supplement for all patients to support NO production, suppress inflammation, enhance oral health, cardiovascular integrity and promote wound healing after surgery
