Electronic Technology - Eye Protection from Blue Light - Role of Lutein Mesozeaxanthin & Zeaxanthin

Blue Light from Electronic Technology. Eye Damaging? That is the concern. Everywhere we are constantly exposed to electronic sources of blue light, including smart phones, computer displays, LED and OLED televisions and car lights. While the light emitted from a smartphone is thought to be in the visible spectrum, there is a very high amount of short wave blue light that is also emitted. LED from cars lights, especially at night, may also pose a problem for the retina. Since we are living longer and are exposed continuously to LED lights, there is real danger the retina may be irrevocably harmed.

Natural sunlight (blue light) also causes light-induced damage to the retina, but are less intense than blue light emissions from LED devices. Therefore LED lights significantly increases the potential for toxicity to the retina. (1-4)

• LED (light Emitting Diodes) - Due to their emitting of blue light, may damage the retina if viewed for long periods of time at close distances. White LEDs have an intense amount of blue light. Blue light is very high energy and as such can cause oxidative stress and tissue damage (including the retina). 
• Some researchers recommend restricting internal LED lamps to "white warmth" - 2700K, which is closer to that of traditional incandescent.
• Avoid "cool white" 5000K - 6500K. The brighter the light the more potential for harm to the retina.

 BLUE LIGHT DAMAGES RETINA

Photoreceptors (cones and rods) in the retina provide the neuron interface to convert light to images. These photoceptors reside on the outermost parts of the retina, and are nourished and maintained by an underlying layer termed the Retinal Pigment Epithelium (RPE). Photo induced stress directly affects the health of the retina. The blue light is especially damaging, increasing oxidative stress and can lead to cellular death to either the photoreceptors or the Retinal Epithelium.

Age-Related Macular Degeneration (AMD)  involves the progressive degradation of the photoreceptors and the  RPE. Blue light can damage and cause cellular death of these critical structures. Oxidative stress and inflammation are believed to be key factors in the development of AMD.

NATURAL PROTECTION AGAINST DAMAGING BLUE LIGHT

• Mesozeaxanthin. Zeaxanthin. Lutein.
  

• Macular Density.
  

   Additionally, lutein, repairs light induced damage to the retinal pigment epithelium (RPE) kayer, which is disrupted by the oxidative stress. Much like the protection of the retina cells, lutein repairs the RPE via invoking the Nrf2 endogenous antioxidant system,(10)

FURTHER PROTECTION

• Bilberry Anthocyanins. Increases Antoxidant Protection of Retina. An experimental model of retinal degeneration, produced by visible-light damage, was ameliorated by the protective antioxidant effects of bilberry anthocyanins. (11)

• Sulforaphane. Most potent Nfr2 Activator. 
  In studies involving the Retinal Pigment Epithelium (RPE), and oxidative stress, sulforaphane was shown to  significantly up regulate antioxidant protection of the RPE by activating Nrf2 and HO-1. (12)

• Aging Increases Damage from Blue Light in PhotoReceptor cells.              Normal protection of the photoreceptor cells and the supporting retiinal epithelium   layer, is provided by the cells inherent Nrf2 antioxidant protection against oxidative stress. However, aging is known to deplete the protective Nrf2 response, leaving the retina even more susceptible to damage by oxidative insults such as blue light. Therefore, not only does blue light inherently stress the retina and may cause cellular death, but this response is greatly amplified with retinal aging.(13-14)

Mitophagy - Maintaining Mitochondria & Stem Cell Renewal for Regenerative Longevity

MITOPHAGY AND  LONGEVITY

• Cellular homeostasis, which significantly includes mitochondria function, is critical for longevity. Mitochondria are the energy powerhouses of the cell and are essential cellular elements for health and longevity. As part of aging, the mitochondria accumulate damage which decreases cellular vitality while increasing dysfunction. Mitophagy is the ability to clean the cell of damaged mitochondria which, if left to accumulate, would cause irreversible loss of cellular energy. Dysfunctional mitochondria can lead to cellular death, degenerative diseases and shorten the lifespan.

• Mitophagy is essential for longevity. Higher activity levels of  mitophagy in the cell has been linked to significant increases in longevity in research animals. Improved aging and extended longevity is correlated with a proper balance of mitochondria biogenesis and mitophagy.(1) Age-related decreases in mitophagy result in the accumulation of damaged mitochondria and a decrease in mitochondria biogenesis, 

• Mitophagy and Autophagy. Mitophagy is the selective degradation of the mitochondria by cellular process known as autophagy. Autophagy is the cellular process used to remove damaged cellular organelles and debris. Increased autophagy is known as a critical component in cellular survival and longevity. Enhanced levels of autophagy is considered a major factor in the  increased longevity in long lived animals.(2)

NRF2 - THE ROLE IN MITOPHAGY AND LONGEVITY  Nrf2 is a latent protein in the cell, which upon activation, regulates the activation of genes which produce antioxidant proteins for cellular protection, reduction of inflammation and reduction of mitochondrial toxins (via glutathione induction).

• Nrf2 Increases Mitochondria Biogenesis and Mitophagy. .

• Stem Cells - The basis for extreme longevity. Extreme lifespans are based on the ability to regenerate new cells to replace damaged cells. This is the function of stem cells. Stem cells are undifferentiated cells which, when needed, can differentiate into replacement cells in the body. Examples where stem cells differentiate into new functional cells include cardiomyoctyes (heart cells) and neurons in the brain. Sources of stem cells include a stem cell pool, whereby stem cells undergo a self-renewal (making new stem cell cells) which supply this pool. Additionally there are specific stem cells such as neural stem cells which can produce new neurons in the brain. Aging, and the dysfucntion of stem cell mitochondria, decrease the functional ability of stem cell self renewal and the regeneration ability of stem cells into cells such as neurons.

• Nrf2 Protects Stem Cells Capacity for Self-Renewal and Differentiation, When levels of Nrf2 are decreased, stem cells and progenitor cells, lose their function for the self renewal and regeneration of cells.. An example of this is seen in neural stem cells in the brain where the ability to stimulate new neuron growth from stem cells  is inhibited when nrf2 levels are low. Researchers believe that nrf2 promotes healthy mitochondria in the stem cells which in turn reverses age related decline in stem cell ability to self-renew and to regenerate new cells. Therefore, nrf2 activation is significant in stem cell self renewal as well as cellular regeneration, including cardiomyocyte regeneration and preserving the function of neural stem cells.(5,6)  

• SULFORAPHANE is a natural and potent Nrf2 Activator and helps maintain youthful and healthy mitochondria. (4, 7)
• SULFORAPHANE - BEYOND Nrf2. In addition to providing Nrf2 activation, sulforaphane helps block damage to the mitochondria through non-Nrf2 mechanisms. Sulforaphane supports mitochondria hyperfusion, which is cytoprotective and prevents the formation of pores in the mitochondria.(8)

Air Pollution - Ultra-Fine Nanoparticles Major Threat for Brain & Lung and Aging

Air pollution is a pervasive and often ignored factor in the aging process. Airborne ultra-fine (nanoparticles) pollution particles are microscopic and pose special dangers to health. Researchers agree that ultra-fine air pollution particles are a major threat in negative health consequences in humans. (1)  While being very detrimental to the lungs, long-term exposure to ultra-fine particles also damages the cardiovascular system, contributes to atherosclerosis plaque formation and may lead to degenerative brain diseases - including Alzheimer's disease. These very small particles are able to travel deep into lung tissue and into the blood stream. As a result, there are significant increases in systemic oxidative stress, inflammation with increased DNA damage and mutagenicity. (2-6) Telomere length, which is an indicator of biological aging, becomes shorter in people living in air pollution areas. Shorter telomeres is associated with accelerated aging.(7-8)

Neuroinflammation. Especially alarming is the effect of ultra-fine particles on the brain. Airborne nano-sized particulate matter migrates through the lungs into the bloodstream and eventually into the brain. Longtime exposure to ultra-fine air pollutants leads to chronic brain inflammation which leads to neurodegenerative diseases. Epidemiological research has linked ultra-fine air particulate matter as a significant environmental  factor involved in Alzheimer's Disease and Parkinson's Disease.(2) 

Ultra-fine pollutant particles are produced by high heat sources including automobiles, trucks, airplane exhaust and factories and play a significant role in health and longevity. Urban areas, transit routes (highways and roads) and airports are major sources of pollutants but the suburbs are not immune. Such pollutants are so small that most people are unaware that they are inhaling toxic pollutants. Airborne fine particulate matter is a major component of air pollution.

Sources of ultra-fine particle pollutants:

(1) City / Urban Areas Particulate Matter. Urban areas create a confluence of major activity which generate ultra-fine air pollution. In studies involving six China urban areas, ultra-fine particulate matter (PM), including polycyclic aromatic hydrocarbon (PAH), were analyzed. The particulate matter was determined as having cytotoxicty to the bronchial cells of the lungs.(9) Substantial sources of outdoor PAHs in particulate pollution include cars and trucks.

(2) Highways / roadways. high volumes of traffic on highways are significant sources of ultra-fine particulate matter and PAH which is then distributed to surrounding areas and runoff into water ways. People living close to major roadways have increased health risks due increased air pollution exposure. Road paving and asphalt manufacturing are also major sources.

(3) Indoor sources. Burning of biofuels including coal and wood create dangerous levels of emissions. Also emissions from cigarette smoke.

(4) Diesel exhaust - classified as a group 1 carcinogen. Shown to cause lung and possibly bladder cancer.Contains nitric oxide and fine particulate matter.

(5) Airports / Aircraft turbine engines - these aircraft engines produce significant levels of hazardous ultra-fine air pollutants (including benzene and formaldehyde) at both in flight and ground levels. In fact, air quality impacts areas extend far from the airports. The LA times reports that communities as far as 10 miles from LAX airport  are exposed to unsafe levels of air pollutants from aircraft engine exhaust.(10)

 Natural Support:

SULFORAPHANE -  Sulforaphane is a potent activator of phase 2 detoxification in the body. In a study in high air pollution areas in China, sulforaphane beverages were shown to signifcantly increase metabolism and excretion of hazardous air pollutants benzene and acrolein in participants.(11)  Further studies indicate that through activation of Nrf2, sulforaphane enhances protection against airborne toxin carcinogens and carcinogenesis. (12) Sulforaphane also protects against oxidant effects of diesel emission by invoking an over expression of antioxidant enzymes.(13)

 N-ACETYL-CYSTEINE - Offers  protection against air pollution induced inflammation. Includes specific mitigation against formaldehyde induced lung damage. Formaldehyde is a major emission toxin from airplane exhaust.(14)

Citrus bergamia risso (Bergamonte®) Bioactives - Promotes Longevity & Cardio Health

The unique flavonoids in citrus bergamia (Bergamonte®) have been previously shown to have potent cardioprotective properties including effective cholesterol support. Further research indicates that citrus bergamia flavonoids have additional beneficial properties which affect disease progression and longevity.(1)

• Cardiovascular Health -  Studies show that Bergamonte® decreases triglycerides, plasma blood glucose and dangerous small LDL particles (VLDL), which damage ateries and accelerate atherosclerosis. Furthermore Bergamonte® increases healthy HDL while maintaining essential levels of large LDL.
• Antioxidant & Anti-Inflammatory - These effects are systemic in nature and are believed responsible for the powerful action of Bergamonte® in supporting cardiovascular health as well as protection against degenerative diseases.
• Longevity: Activates AMPK - AMP kinase (AMPK) is involved in an important regulator of glucose and fatty acid metabolism. AMPK activation is tightly coupled with longevity, including "energy metabolism, stress resistance, and cellular proteostasis."  AMPK signaling is involved with activation of other longevity activators including FOXO and SIRT1. AMPK activation becomes inhibited with age. (2)  Bergamonte® activates AMPK.

Herbal Extracts - Neurogenesis & Recovery of Cognition Impairments

Aging of the brain involves the loss of neurons (hippocapmus shrinkage), loss of synapse integrity between neurons, build-up of toxic amyloid proteins, neuron tangles, defects in blood flow  and chronic inflammation. Under normal age progression, these events do not happen over night and may take years before impairments in cognition become noticed.

Ultimate anti-aging strategies for the brain and memory should target the progressive decline of the brain and promote reversal and recovery of some cognition impairments.

Emerging research in the study of herbal ingredients show their tremendous potential use in mitigating the decline in brain function with age.

• NEUROGENESIS - is the formation of new neurons, specifically in the hippocampus area in the brain.The hippocampus is essential in providing the capacity for memory and learning. Dementia and Alzheimer's disease are associated with brain shrinkage which is correlated to the loss of neurons in the hippocampus. The formation of new neurons may reverse brain shrinkage.

                    Herbs and Extracts

•  Andrographolide - As an extract from Andrographis Paniculata. Lab research has shown stimulation of neurogenesis in the hippocampus by andorgrapholide. Specifically " increased cell proliferation and the density of immature neurons in the dentate gyrus." (1) The dentate gyrus is an area of the hippocampus involved in memory formation.
• Centella asiatica - Acts as a potent memory enhancer, via  increasing hippocampus neurogenesis and support for brain tissue regeneration. (2)
• Baicalin (3)
• Panax Ginseng (4)
  
• Curcumin (5)
• Epimedium (Icariin)  (6)
• Apigenin (7)
  

• BRAIN TISSUE REGENERATION. While in the same theme as neurogenesis, brain tissue regeneration refers to the enhancement and regeneration of critical neuron structures - axons and dendrites. Dendrites transmit signals from the synapse to the body of the neuron. Axons transmit signals away from the body of the neuron and are covered with a myelin sheath which increase speed of the impulse providing rapid impulse transmission. Aging degenerates the structural integrity of dendrites and axon/myelin complex.
  

                     Herbs and Extracts

•  Centella asiatica - Improves structural integrity of axons / myelination and proliferation of dendritic branching and length. Such improvements have been shown to enhance learning and improve memory. (8) Centella asiatica also has been shown to improve learning and memory in normal lab mice.
• Luteolin - Baicalin - promote neuronal survival and neuron differentiation through the outgrowth of neurites  (axons and dendrites) from the neuron.(9.10)
• Rosemary (Carnosic Acid) - Strongly promotes neurite outgrowth as a function of powerful Nrf2 activity. Suppressed Nrf2 activation suppresses neuron differentiation.(11)

• RECOVERY OF COGNITIVE IMPAIRMENT - the  to reversal of certain functional impairments which may improve cognitive function. Many research animal models for cognitive impairment are characteristically similar to Alzheimer's disease (AD). Impairment usually involves cerebral vascular disease, synaptic dysfunction. and more.

          Herbs and Extracts

• Andrographolide - Impairment of synaptic function between neurons plays a significant role in the loss of cognitive function. This is seen in the progression of AD. In research animals with AD-like cognitive disease, the treatment of andrographolide over a 3 month span imporved synaptic function and protected important synaptic proteins.
• Furthermore, andrographolide has been shown to reduce inflammation in the brain and levels of pathological tau protein and beta amyloid in animal models.(12)
• Andrographolide reduces inflammation and dysfunction of the cerebral endothelial cells, which may affect vascular flow to the brain.(13)
• Centella asiactica - in senescence-accelerated lab mice, which had accelerated aging of the brain, administration of centella asiatica significantly improved synaptic plasticity and reduced beta amyloid build-up. Such treated mice showed significant benefits in memory and learning. (14)

• NEUROPROTECTION - AMYLOID & NON-AMYLOID (α-synuclein) TOXICITY | CHRONIC INFLAMMATION - The aging brain is under continual assault and must be protected to prevent cognitive decline and loss of neurons. Key areas of protection include the build-up of amyoid plaques which are toxic to neurons and synapses. Moreover, chronic inflammation in the brain accelerates destruction of the brain and is believed to be the facilitator of degenerative brain diseases.
• Centella asiatica (15)
  
• Epimedium (Icariin)(16,17)
• Apigenin and luteolin (18,19)
  
• Baicalin (20)
  
• Schisandra (21)
• Rosemary (Carnosic Acid)(22)

• REVERSES INSULIN RESISTANCE IN BRAIN NEURONS - Aging brains become increasingly incapable of using glucose as an energy source. Without this energy neurons age faster and die. Reversing the insulin resistance maintains healthy neurons. Brain insulin resistance is associated with Alzheimer's Disease.
• Further reduction in glucose availability is caused by methylglyoxal - a powerful intermediate in the formation of Advanced Glycation End Products (AGEs).
• Curcumin - Improves insulin sensitivity in neurons. (23)
• Sulforaphane - Reverses reduction of glucose uptake by neurons caused by methylglyoxal (a precusor of advanced glycation end products). Sulforaphane also normalizes brain-derived neurotrophic factor (BDNF) signaling, which is critical for maintaining brain function. BDNF pathways are disrupted in Alzheimer's Disease. (24)

Repairing Blood Vessel Lining - For Longevity & Cardiovascular Health

Endothelial cells form the structural basis of the lining of blood vessels (the endothelium).  Damage to the endothelium affects the ability of the blood vessel to function and increases with age. Endothelial Progenitor Cells (EPCs) function to repair damage to the endothelial of blood vessels and are considered important in the prevention of cardiovascular disease. Furthermore, since healthy arteries are vital in supporting longevity, improving the function of EPCs plays an important role in extending lifespan.

Taurine and Magnesium. Administration of taurine and magnesium to lab animals resulted in significant increases in EPC colonies, enhancing endothelium repair and function. Aging is associated with decreased levels of EPCs, a significant factor in endothelium damage and impairment of vascular maintenance and homeostasis.  Because EPCs have significant potential to repair the lining of blood vessels, researchers concluded that dietary intake of taurine and magnesium may extend lifespan by improving cardiovascular function and preventing the progression of cardiovascular disease.

Air Pollutants Outdoor Indoor Exercising - Detoxification

Air pollutants are harmful and affect everyone, but may be additionally detrimental for people who exercise  at higher levels (with higher inhalation rates) both outdoors and indoors. Since runners, bikers, aerobics class participants and other fitness buffs, require more oxygen and deeper inhalation. they typically inhale higher level of pollutants. For example, a fitness center study comparing the inhalation of pollutants of  indoor aerobics class vs. less intense activity, showed 2x's the amount of pollutants inhaled by the higher intensity aerobics class. (1) Moreover, the air pollutants tend to become trapped deeper into the lung tissue. Furthermore,  air pollutants are most often not apparent and the fitness ethusiast is unlikely to be aware of the inhalation hazard.

Air pollutants have been associated with respiratory mortality (3), development of atherosclerosis (2), diabetes (5) and neuropatholgies (via increased neuro inflammation) (4). While doctors support the need for exercise, many will caution about exercising outdoors, especially where  air pollution levels may be higher.

SOURCES OF AIR POLLUTION:

• Indoor environment (Fitness Centers, Home)
• Outdoor environment (Suburban - Urban - Transit areas)
• Ambient Air
• Automobiles
• Buses / trucks (Diesel Exhaust)
• Airports / Airplanes
• Factories

SULFORAPHANE DETOXIFICATION

 Sulforaphane is a powerful phase 2 detoxifier, which enables the detoxfication and excretion of harmful pollutants and toxins. In a clinical trial in china, glucoraphain in  broccoli sprout (beverage), which contains the powerful precursor of sulforaphane, was shown to effectively detoxify several major air pollutants.(6) Compared to placebo,  the broccoli sprout beverage showed "rapid and sustained increases in the levels of excretion of the glutathione-derived conjugates of benzene (61%), acrolein (23%)". Another study,  also showed increased excretion of the air pollutant crotonaldehyde.(7)

Effective results showed  detoxification of airborne pollutants from study participants.(6,7) Sulforaphane may also have an inhibitory effect against cancer, including lung cancer, via activation of Nrf2 antioxidant pathway. (10)

Diesel Exhaust Fine Particles - The fine particles form diesel exhaust are considered a significant health hazard which impacts especially outdoor exercise. At high cardiac output, diesel increased pulmonary vasoconstriction (8) and increased oxidative stress and allergic inflammatory response.(9) Sulforaphane induces phase II enzymes which can block the oxidant and allergic inflammation harmful effect of the diesel exhaust particles. (9)
