Scientists discover new mechanism of how brain networks form
January 15, 2017 12:59 PM
As long as neurological disorders have been diagnosed, scientists have tried to determine how the brain works in order to better treat them. One thing we do know about the brain is that it creates maps of experiences that help us learn. As we learn, these maps are altered to adapt to our surroundings. Excitatory neurons in the brain have been found to narrow their scope upon learning new information. Inhibitory neurons, conversely, have recently been found to get broader when learning. This new understanding of neurons will go far in efforts to repair brain tissue.
"Scientists have discovered that networks of inhibitory brain cells or neurons develop through a mechanism opposite to the one followed by excitatory networks."
Superaging: why some 80 year olds have the memory capacity of 20 year olds
November 08, 2016 09:54 AM
Superagers is a term used by researchers to describe a minority of senior citizens who appear to maintain memories as dependable as those many years younger. Science is just beginning to explain why superagers have such strong memories. While certain sections of superagers’ brains may deteriorate, their memory networks stay as functional as those of an 18-32 year old person. Neurology researchers at the Journal of Neuroscience are surprised by these recent findings. By observing superagers, researchers hope to learn more about the slowing down of cognitive function and the conditions associated with it.
"Now, researchers have provided some insight as to why and how some of our senior citizens are able to hold on to their robust memories."
EGCG in green tea

Green tea benefits
Green tea is made from the leaves of Camellia Sinensis, which is recognized for its health benefits. The nonfermented product is obtained by leaf desiccation that contains potent, polyphenolic antioxidants, with a flavanolic structure referred to as green- tea catechins, including epigallocat-echin-gallate (EGCG). Studies have shown that drinking EGCG prevents carcinogenesis in rodent organs. Studies have shown it had a significant chemoprotective effect against DMBA-induced mammary tumorigenesis in rats. Human breast cancer cell proliferation inhibition by green tea appeared mediated in part by (CKI). Mutagenesis was inhibited at concentration levels equivalent to human daily consumption.
Using human umbilical vein endothelial cells, it was demonstrated that green tea extracts reduced expression of vascular endothelial growth factor (VEGF) receptors forms-like tyrosine kinase and fetal liver kinase. Kinase insert domain containing receptor. Because of the antiangiogenic property of its extracts, they have therapeutic potential in preventing the development of new microvascular networks (angiogenesis) needed for tumor growth. It was also found that green- tea polyphenols inhibited angiogenesis by reducing vascularization of chicken chorioallantoic membrane (CAM) by an angiogenin-like protein isolated from goat serum.
EGCG effectively inhibited bladder-tumor implantation growth in rats, pointing to its potential as an intravesical chemotherapeutic agent. Inhibition of platelet function is a factor in reducing the risk of coronary artery disease. EGCG was reported to inhibit platelet aggregation, by possibly involving inhibition of cytoplasmic calcium increase. EGCG was proven to be the most effective in reducing thrombin-induced aggregation of washed human platelets. The ability of green- tea catechins to inhibit adenovirus infection and adenain, the human adenovirus 2 endopeptidase, was reported. EGCG proved the most potent inhibitor of four green-tea catechins tested. The viral protease adenain appeared to be the target of EGCG, so it is possible that all adenoviruses are sensitive to its action.
The Chinese have known about medicinal qualities of green tea since ancient times, treating everything from headaches to depression.
The three "Es"
Provides support for a healthy weight loss program, gives the energy needed to maintain an active lifestyle, health, and longevity. The appetite suppressor, Vanadium, reduces calorie intake. Thermogenesis, or fat metabolism, is increased, because of the EGCG/caffeine combination, therefore burning fat.
EGCG fights free radicals. Fatty acids and lipids in the brain are susceptible to the effects of free radical perodixation. Much of the aging of the brain is attributed to perodixation. The EGCG helps to keep us young, alert, and able. Researchers have found that EGCG has inhibited tumor growth in both skin and gastrointestinal tracts. EGCG may fermented be able to obliterate cancer cells, without harming neighboring tissues.
What are the Essential Amino Acids we must get from our Diet to Survive?
August 17, 2011 12:13 PM
Amino acids or the building blocks of protein are very important in overall functioning of the body. Proteins, to mention, are responsible for the build up of most of our body parts specifically our muscles, ligaments, tendons, organs, tissues, glands, nails and hair. Moreover, the repair and preservation of those parts still rely on proteins. Amino acids can be of two different forms which are the non-essential and essential. On this selection, we will be focusing more on the latter.
Essential amino acids are those which cannot be produced by the body therefore it has to be supplied through our diet. This category of amino acids includes tryptophan, lysine, methionine, valine, leucine, isoleucine, threonine and phenylalanine.
Tryptophan, which is a precursor to serotonin and melatonin, can be acquired from peanuts, meat, turkey, fish, milk, dried dates, cottage cheese, banana, oats and chocolates. A deficiency of this can bring up serious neurological problems, depression, anxiety and sleeping difficulties.
Another essential amino acid is methionine. The production of sulfur and other compound needed for a healthy growth and metabolism depends on the presence of this amino acid. Fish, whole grains and dairy are its sources.
Lysine, which is effective in the treatment and prevention of herpes, is present in soybeans, green beans, lentils, spinach and amaranth. Low levels of lysine can also compromise the levels of niacin and this leads to pellagra.
Tissue healing, muscle metabolism and keeping the equilibrium of nitrogen levels in our body are the functions of valine. It has proven to be efficient in the treatment of liver and gallbladder disorders. Deficiencies that results from drug addiction are can also be reversed by this amino acid. Its sources are peanuts, soy proteins, dietary products, grains, meat and mushrooms.
Leucine can be obtained from chicken, fish, cottage cheese, lentils, peanuts and sesame seeds. It functions in muscle protein build up and is the main medium in tissue building process. Inability to acquire such makes a person prone to protein wasting since leucine, together with valine and isoleucine, serves as energy and protein reservoirs.
In boosting energy levels, blood sugar regulation, muscle build - up and repair as well as hemoglobin development, isoleucine has shown its relevance. Its dietary sources are fish, poultry, beef, dairy, eggs, lentils, seeds, soy, almonds and wheat. Isoleucine deficiencies may result into neurological disturbances such as confusion, depression, irritability, fatigue, headache and dizziness.
Threonine is significant in synthesis of antibodies. Beans, nuts, seeds, dairy, poultry, eggs and beef are rich in threonine. A low level of this amino acid causes disorders of the skin and weakness.
Adrenaline and noradrenalin which are stimulates the central and peripheral nervous system requires phenylalanine to perform their function. Phenylalanine can be acquired from peanuts, seeds, almonds, lima beans and dairy. Liver damage, weakness, skin lesions, lethargy and slowed growth are results of its deficiencies.
In summary, our body needs networks of essential amino acids for its proper functioning. Eating healthy foods and living a healthy lifestyle is the secret towards maintaining your optimum general health.

Medical professionals, especially in Europe and Japan, have been using licorice more and more in medicine. The Chinese consider licorice to be a superior balancing and harmonizing agent, so it is added to many herbal formulas. It is reputed in many countries, including the United States, to be a treatment for stomach, intestinal and many other problems. What is it used for?
Licorice is being studied for its effects against oxidation of LDL cholesterol, which is a major component in atherosclerosis. Approximately 300 different phytonutrient compounds found in natural licorice are considered possible antioxidants.
Licorice is being tested for its ability to help prevent certain viruses from replicating themselves in body cells. It appears to stimulate the immune system into producing interferon, which is known for its anti-viral effects. It is an effective aid in treating herpes and hepatitis. Promising results are also being reported in tests using licorice to combat SARS, influenza and HIV.
Stomach and Intestinal Problems
Licorice is a natural home remedy for heartburn, gastritis and acid reflux. It helps to promote new cell growth in the lining of the stomach. It also enhances the stomach's self-protecting abilities. Licorice has been used to treat peptic ulcers and aid in healing other types of ulcers.
Throat and Respiratory Problems
Licorice is widely known in the world of alternative medicine as an expectorant and cough suppressant. Colds and flu have been treated with licorice since the days of the Romans. Many over-the-counter cough medicines contain licorice extract because it soothes the mucous membranes.
Other Medicinal Properties
Is Licorice Safe?
Licorice is not recommended for use by people who suffer from diabetes mellitus, heart disease, hypertension or kidney disease. It is also not recommended for use by women who are pregnant or breast-feeding.
Licorice, although not thought to suppress the immune system like pharmaceutical cortisones, may cause similar side effects in high doses. Some of these include weight gain, fluid retention and high blood pressure.
Description and Cultivation
The licorice plant stands up to five feet tall. It has spikes of lilac-colored flowers that have bean-like pods containing three or four seeds apiece. The root, which is used most frequently, reaches underground about three feet and branches into networks of rhizomes.
After three to five years, the roots and rhizomes are cleaned, pulped, boiled and then concentrated by evaporation. The root, if kept dry, will keep for an indefinite amount of time. If the licorice is powdered, it should be stored in an airtight container.
Licorice has been used for centuries in conjunction with established medicine, as an alternative herbal medicine, and as an herbal confection in many parts of the world. It is noted for its medicinal value in treating stomach, intestinal and other ailments, including helping to stimulate the immune system. Studies are ongoing to discover more potential uses for this naturally sweet herb.
Immunity - The Big Picture
June 10, 2005 09:51 PM
Immunity: The Big Picture by Brian Amherst Energy Times, August 3, 1999
Your body wants to be well. Outfitted with a battalion of defenses for strategic deployment, your immune system explodes with resistant force at the first sign of infective invasion.
Think of the time a tiny splinter embedded itself in your thumb. By bedtime, the spot rose and reddened; by morning, white blood cells had launched their campaign, building a hot, throbbing fortification. By day's end, the bit of wood was propelled to the surface and ejected by the immune system warriors. Once again, a foreign assailant was summarily ousted.
The Protective Force
"Supporting the immune system is critical to good health. Conversely, good health is critical to supporting the immune system." So write naturopathic doctors Michael T. Murray and Joseph E. Pizzorno in their Encyclopedia of Natural Medicine (Prima).
Maintaining the immune system requires a comprehensive program of wholesome diet, resilient attitude, fitness enhancing activity and nutrients keyed to the clear and specific needs of this energetic machine.
The all-star lineup for immune sustenance: a high-potency multiple vitamin/mineral formula, vitamins C and A, bioflavonoids, isoflavones, zinc and selenium, antioxidants like ActiVin (grape seed extract) and pycnogenol (French maritime pine bark), as well as the botanicals echinacea and astragalus.
But optimal partnering with your immune system also benefits from understanding its workings.
Lymph, a milky fluid consisting of water protein and immune cells, is the essence of the immune system. Powered by muscle movement (an important reason why exercise boosts immunity), the lymphatic system collects and transports lymph to the lymph nodes. These nodes contain certain immune cells and filter out invading antigens, as well as produce antibodies, before siphoning the lymph out into the bloodstream.
If you've ever had "swollen glands," that means your lymph nodes have been in overdrive.
Macrophages are the immune cells that filter lymph, consuming bacteria and cellular debris while protecting the lymph system from invasion and damage.
The White Blood Cell Album
In Monocytes collect cellular trash after infections and can trigger immune responses; eosinophils can eliminate foreign particles and, with basophils, are involved in immune response.
In Lymphocytes include varieties of T cells, which work with other white blood cells or attack and destroy foreign tissue, cancer cells or virus-infected cells; B cells that produce antibodies that bind to bacteria, viruses or tumors; and natural killer cells (NKCs) that destroy cancerous or virally-infected cells.
(Based on information in the Encyclopedia of Natural Medicine; The Road to Immunity: How to Survive and Thrive in a Toxic World (Pocket Books) by Kenneth Bock, MD, and Nellie Sabin; and the Johns Hopkins Family Health Book (Harper Resource).
Keep the System Sound
"But you must always be sure to maintain the mind-body-spirit link," he told Energy Times. "For the mind, it could be exercise, yoga or meditation. Evidence shows improved immune system responses from these therapies. And in any case, you never read in the headlines that somebody has been admitted to the emergency room overdosing on meditation.
"Intentionality also is an important part of the mind link: believing you are going to fare well. For your spirit, you must ask yourself such questions as, Do I feel connected to others?
"For the body, a daily multivitamin and mineral supplement. Much depends on your community: I live on Long Island, where there is a high incidence of breast cancer, so I would recommend green tea and isoflavones from soy products for women."
Dr. Benjamin stresses moderation in the use of immune-intensifying supplements, among which he cites mixed carotenoids, zinc and vitamin E.
The Soy Solution
In a study conducted by the University of Southern California at Norris and published in the March 4, 1998 Journal of the National Cancer Institute, researchers reported that genistein, an active component of soy products, short-circuits the ability of tumor cells to elude destruction by the immune system due to an excess of defensive stress proteins.
Genistein seems to make cancer cells vulnerable to the immune response. Researchers at Wake Forest University told participants at the January 1999 meeting of the American Association for the Advancement of Science that dietary or supplemental soy fed to monkeys counteracted cell proliferation that is a cancer precursor.
That Championship C
Immune cells are known to accumulate and retain high levels of vitamin C. Researchers at Memorial Sloan-Kettering Cancer Center in New York now understand how that happens: Proteins called growth factors (which control growth and production of immune cells) also increase those cells' ability to take up vitamin C.
These researchers, reporting in the April 1998 issue of the journal Blood, explain that the additional glucose that the growth factors pump into immune cells (for enhanced energy), plus extra vitamin C, intensify immune response.
And folks with higher levels of vitamin C in their blood serum experience less cell damage from free radicals that leads to cancer, heart and pulmonary disease and other chronic conditions.
Scientists at the University of Buffalo (addressing the June 13, 1997 meeting of the Society for Epidemiologic Research) deduced from studying population groups that high levels of vitamin C are associated with low oxidative stress and lower risk of cell damage.
From A to Zinc
In Colostrum, the pre-milk liquid produced by mammals during the first 24 to 48 hours after birth, took the spotlight recently as a supplement imbued with multiple immune factors and natural antibiotics that augment body's immune response. A 1992 study showed that bovine colostrum might be able to reduce and prevente infections in immune deficient folks, especially those with AIDS.
In University of Pittsburgh Cancer Institute researchers found for the first time (on laboratory animals) that vitamin D appreciably inhibits widespread prostate cancer by binding to cancer cells and triggering cell death or their transformation to benign cells.
In Vitamin E exerts formidable immune-enhancing influence on both antibody and cell-mediated immunity. One fundamental study in the Journal of the American Medical Association (245, 1981: 53-58) established conclusively that vitamin E deficiency results in significant impairment of immune function. Later studies demonstrated that it reduces prostate cancer by up to one-third.
In Coenzyme A, described as a metabolic enzyme, takes part in starting numerous body processes that provide energy for the immune system. If you ever run short of this enzyme, fat processing within your body would grind to a halt.
in Researchers looking at a substance with the tongue twisting name 3-acetyl-7-oxo-Dehydroepiandro-sterone, believe it aids immunity by quelling stress hormones.
in Mushrooms contain natural substances called polysaccharides, believed to enhance immunity. In particular, maitake mushroom, which conveys the immune booster beta-D-glucans, is reputed to help fight infections and drop blood pressure.
in Men and women taking selenium supplements for 10 years had 41% less total cancer than those taking a dummy, according to a January 1997 study by Cornell University and the University of Arizona. Other studies have shown it to reduce the risk for colon cancer by about 60%. n Zinc may provide immediate protection against the all too common cold. Scientists at the University of Florida were the first to apply genetic fingerprinting methods like those used in criminal and paternity investigations to understand how nutrients directly affect human immune cells.
The study, in the April 1998 Journal of Nutrition, demonstrates that zinc signals cells to make the protein metallothionein, which protects against infections, toxins and other stressors.
Phytochemicals a la Carte
n Isoflavones from soy, fight angiogenesis, the process by which new blood vessels form to supply nutrients to cancerous growths. n Sulforaphane in broccoli, kale and cabbage activates anticancer enzymes.
n Omega-3 fatty acids in cold water fish block the synthesis of prostaglandins, natural compounds in the body that promote tumor growth.
n Ginger contains antioxidant compounds, each more potent than vitamin E. Recent studies on mice show ginger can prevent skin tumors. n Rosemary contains carnosol which deactivates carcinogens and helps limit the effects of prostaglandins.
Sometimes the world can look like a dangerous place, especially when you're sick and tired much of the time. But in the search for immunity, menus of health help like this ensure that no matter what your immunity needs, a boost can be yours with the proper nutrient selection.
Mushroom Immune Defense - Scientific Immunity Formula
June 04, 2005 10:08 AM
The immune system is a fascinating and complex group of cells and biochemical processes. Its many components work to protect you from environmental threats—but your immune system requires nutritional support to function optimally. Scientific research is proving that some of the most powerful immune-supportive nutrients are found in mushrooms. People who realize the critical importance of optimizing immune function should seriously consider adding an advanced mushroom complex to their daily regimen. No other mushroom formula offers the high-potency, broad-spectrum benefits of Source Naturals MUSHROOM IMMUNE DEFENSE. MUSHROOM IMMUNE DEFENSE features 16 of the best-studied species of health-supportive mushrooms, including shiitake, reishi, and maitake. These mushrooms contain compounds, including beta-glucans, glycoproteins and polysaccharides, that support a wide range of immune defenses: natural killer cell, T-cell and macrophage activity, and cytokine production. By combining a wide variety of mushrooms and fortifying them with extracts to ensure high potency, MUSHROOM IMMUNE DEFENSE offers a biochemically diverse formula that provides optimum immune assistance.
How Do Mushrooms Work?
Mushrooms are a treasure trove of bioactive compounds, but most of their immunomodulating activities have been attributed to polysaccharides (long-chain, simple sugars) and glycoproteins (polysaccharides naturally associated with proteins). These compounds activate a variety of immune responses.
MUSHROOM IMMUNE DEFENSE contains mycelia (networks of fibrous filaments) and extracts from the widest variety of mushroom species available. Included are the following mushrooms, which have demonstrated the most evidence for immune defense. Shiitake (Lentinula edodes): Lentinan, the beta glucan from shiitake, has been studied more extensively than similar substances and may be one of the most effective immunomodulators. Numerous studies have shown its ability to stimulate natural killer cell, T-cell, and macrophage-dependent responses.
Reishi (Ganoderma lucidum): Reishi’s polysaccharides may stimulate macrophages and enhance T-cell proliferation, according to in vitro studies.
Maitake (Grifola frondosa): Maitake enhances the activities of natural killer cells, T-cells and macrophages, according to animal studies. MUSHROOM IMMUNE DEFENSE contains MaitakeGold 404™, a highly specialized maitake product, rich in beta-glucans, which is the only maitake betaglucan fraction endorsed by the world’s premier maitake researcher, Dr. Hiroaki Nanba, Ph.D. Turkey Tails (Trametes versicolor): These mushrooms have a long history of traditional use in Asia. One in vitro study suggests that its polysaccharides stimulate macrophages.
Almond portabella (Agaricus blazei): This mushroom may stimulate the immune system by increasing T-cell activity, according to animal studies.
Cordyceps (Cordyceps sinensis): Cordyceps came to international attention during National Games in China when, in one week, three women’s track and field world records were broken. The coach partially credited a cordyceps elixir. Cordyceps was found to augment antibody and other immune responses in one animal study, and a cordyceps polysaccharide was found to elevate cytokines in vitro.
MUSHROOM IMMUNE DEFENSE contains 10 additional mushrooms, including enoke, oyster, Polyporus umbellatus, and Poria cocos. Vitamin C is added to enhance absorption and activity.
