A group of researchers from the University of Helsinki and the University of Edinburgh have been the first to find the genetic material of a human virus from old human bones. Published in the journal Scientific Reports, the study analyzed the skeletal remains of Second World War casualties from the battlefields of Karelia.

Upon infection, many viruses remain in the tissues and their DNA can be analyzed even decades thereafter. Although their genetic material has been found in many organs, the researchers show that viral DNA is also present in bone.

“Human tissue is like a life-long archive that stores the fingerprint of the viruses that an individual has encountered during his or her lifetime,” describes Klaus Hedman, professor of clinical virology.

The finding has important implications since bone is most likely to be preserved after death, thus opening the door to the study of the viruses that caused infections in the past. In a publication in Scientific Reports, the researchers show that this is indeed the case. They document the presence of parvovirus DNA in the bones of Finnish World War II casualties who remained exposed to diverse climatic conditions in former Finnish, current Russian territory, until recent years when they were repatriated to their homeland.

(KPIX 5) — This might come as a surprise to California natives in their 20s and early 30s: The state owns your DNA.

Every year about four million newborns in the U.S. get a heel prick at birth, to screen for congenital disorders, that if found early enough, can save their life.

Danielle Gatto barely remembers the nurse even mentioning test performed on her two daughters. “I don’t think that any woman is in a state of mind to sit down and start studying up on the literature they send you home with,” she said.

But later she was shocked to find, her daughters’ leftover blood was not thrown away. “The state collects the cards and then uses them in a database,” she said. The information is buried on page 12 of the brochure about the Newborn Screening Program that hospitals give parents of newborns before they go home.

Turns out a non-descript office building in Richmond contains the DNA of every person born in California since 1983. It’s a treasure trove of information about you, from the color of your eyes and hair to your pre-disposition to diseases like Alzheimer’s and cancer.

Vanderbilt researchers discover new DNA repair enzyme

Vanderbilt University researchers have discovered a new class of DNA repair enzyme, according to findings published in the journal Nature.

After originally discovering the structure of DNA, scientists thought that it was a chemically stable blueprint of traits that was difficult to alter. However, in the decades since, scientists have found that the double helix molecule is extremely reactive and subject to damage. Cells must constantly work to repair damaged DNA, and that’s where DNA repair enzymes come in.

“It’s a double-edged sword,” said Brandt Eichman, an associate professor of biological sciences and biochemistry at Vanderbilt and the leader of the research team behind this discovery. “If DNA were too reactive then it wouldn’t be capable of storing genetic information. But, if it were too stable, then it wouldn’t allow organisms to evolve.”

Damaged DNA

DNA can be damaged either by environmental factors like toxins and UV radiation, or by wear and tear as a result of cell processes.

More than a mile beneath the ocean’s surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.

Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells.

Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur reserves, then use the unleashed energy to replicate.

“Our findings suggest that viruses in the dark oceans indirectly access vast energy sources in the form of elemental sulfur,” said University of Michigan marine microbiologist and oceanographer Gregory Dick, whose team collected DNA from deep-sea microbes in seawater samples from hydrothermal vents in the Western Pacific Ocean and the Gulf of California.

“We suspect that these viruses are essentially hijacking bacterial cells and getting them to consume elemental sulfur so the viruses can propagate themselves,” said Karthik Anantharaman of the University of Michigan, first author of a paper on the findings published this week in the journal Science Express.

Similar microbial interactions have been observed in shallow ocean waters between photosynthetic bacteria and the viruses that prey upon them.

But this is the first time such a relationship has been seen in a chemosynthetic system, one in which the microbes rely solely on inorganic compounds, rather than sunlight, as their energy source.

“Viruses play a cardinal role in biogeochemical processes in ocean shallows,” said David Garrison, a program director in the National Science Foundation’s (NSF) Division of Ocean Sciences, which funded the research. “They may have similar importance in deep-sea thermal vent environments.”

Prevent Disease

 

April 30, 2014 by DR. SUZANNE BARTOLINI

The levels of radiation that we are constantly exposed to have risen dramatically over the last half century. Ambient fallout from nuclear catastrophes is impacting our environment, and ultimately our health, as we all come in contact with radioactive materials. Here’s how to protect yourself.

The bombings of Hiroshima and Nagasaki in 1945, the Chernobyl nuclear disaster in 1986, and the most recent 2011 Japan Tsunami calamity at Fukushima nuclear power plant have each had devastating consequences for the environment, damaging the ecosystem and the quality of our air, water, and soil.

The greatest health consequences of a nuclear accident or explosion are linked to radioactive materials (radio-nuclides) that can travel through air and water for thousands of miles, contaminating the world with radioactive particles. Once the human body is exposed to nuclear fallout, radioactive isotopes can remain in the body for many years, causing unpredictable chemical reactions. Absorption of radiation, especially over prolonged periods of time, can result in free radical damage, mutational damage to DNA, and cellular dysfunction, inducing several diseases. Symptoms of radiation toxicity can include fatigue, migraines, infertility, allergic reactions, hypertension, disorders of the central nervous system, anxiety, memory loss, rheumatic pains, flu-like symptoms, low red and white blood cell counts, etc.
Ionizing and Non-Ionizing RadiationThere are two types of radiation: ionizing and non-ionizing. Both types cause DNA damage and form harmful free radicals. Ionizing radiation is produced from nuclear reactors, nuclear bombs, nuclear waste, and diagnostic equipment like x-rays and CT scans. Ionizing radiation is considered the most harmful. The most common diseases linked to ionizing radiation include thyroid disease, leukemia and various cancers, anemia, bone and blood disorders, endocrine (hormonal) disruption, reproductive abnormalities and birth defects, kidney and liver damage, and overall severely damaged immune systems.Non-ionizing radiation is a type of electromagnetic radiation produced by electronic devices such as televisions, cell phones and towers, wireless devices, computers, high voltage electrical lines, radios, microwaves, etc. Non-ionizing radiation disrupts molecules as it passes through the body, and there is an increasing body of research demonstrating that exposure to electromagnetic frequencies (EMFs) can alter the behaviour of cells and hormones. For example, EMFs can cause the body to reduce production of the hormone melatonin, affecting immune processes and causing increased defects, sterility, and fetus mortality rates in laboratory animals. In 1987, scientists discovered a significant link between increased incidence of childhood cancer and close proximity to high tension power lines and commonly used electronic devices.Radiation-induced Thyroid DiseaseA variety of dangerous radioactive materials are known to be released during nuclear power plant accidents. Among the most worrisome are cesium-137 and iodine-131, which emit Gamma rays and have affinities for parts of the human body. Cesium-137 mimics potassium inside the body and accumulates mainly in the liver, kidneys, and the reproductive system. Iodine-131 is rapidly absorbed by the thyroid gland and increases the risk of thyroid growths and cancer.

And radioactive emissions are not limited only to nuclear accidents. According to Professor Ernest Sternglass of the University of Pittsburgh School of Medicine, an expert on radiation physics: “By design, nuclear power reactors must regularly release steam to lower the intense heat produced. Invisible radioactive particles are emitted into the atmosphere along with the steam and are carried on air currents, eventually falling to the ground with rain and snow… Many cancer hot spots are related to nuclear fallout carried by wind currents from distant locations, which later come down with rain or snow over a particular area, raising the cancer risk among a local population that received the precipitated radioactive fallout.”

The thyroid gland is the first to uptake radioactive iodine, and even when small amounts are inhaled or ingested they will concentrate in the thyroid gland. Most North Americans are iodine deficient which makes them more vulnerable to radioactive iodine. If there is an iodine deficiency in the diet, radioactive iodine-131 will be absorbed and accumulate in the thyroid gland because the thyroid does not distinguish between radioactive and non-radioactive iodine. Having adequate iodine in the body therefore prevents radioactive iodine from attaching to the thyroid gland.

Potassium iodide pills can be taken to prevent the uptake of radioactive iodine in the event of a nuclear accident. Supplementing with potassium Iodine (KI) in either pill form or saturated liquid form (super saturated potassium iodide or SSKI), is the best way to quickly load iodine into the thyroid. Potassium iodine (KI) can be administered in prophylactic doses within 24 hours of exposure in radiation emergencies, and for a short period of time after exposure. In 1986 after the Chernobyl accident, people who were administered potassium iodide experienced less childhood thyroid cancers compared to those who were not. The World Health Organization also recommends potassium iodide supplementation to prevent the thyroid’s uptake of radioactive iodine.

Consuming natural sources of iodine helps offset the side effects of radiation exposure. The best natural source of iodine comes from seaweeds (also referred to as sea vegetables), however there is renewed controversy surrounding seaweed that may be harvested from polluted ocean waters. Kelp is perhaps the most well-known seaweed; others include wakame, kombu, dulse, nori, hijiki, and arame.

In North American studies, seaweed was found to neutralize radioactive isotopes in the human body. Researchers discovered that certain radioactive materials can bind to the algin in brown seaweeds to create “sodium alginate” which has a unique quality in that it can bind heavy metals and radioactive elements, preventing their absorption by the body. In one Canadian study, sodium alginate from kelp reduced radioactive strontium absorption in the intestines by 50 percent to 80 percent.

Other Nutritional and Antioxidant Treatments for Combating RadiationA large number of nutrients and foods are suggested as being helpful in preventing or limiting, or even counteracting, the effects of nuclear radiation. Below are some that are especially noted for their beneficial effects:

MISO — this fermented food made from soybeans has long been used in Japan for both protection from radiation, detoxification, and for stimulating the immune system. Miso is also well-documented to benefit circulation and remove blood clots. Miso soup was used as the primary antidote for the effects of radiation poisoning after the Hiroshima bombing. A 1990 Hiroshima University study concluded that people who regularly consume miso soup may be up to five times more resistant to radiation poisoning than people who do not.

SPIRULINA — is a blue-green algae that is extremely rich in nutrients. It contains beta carotene, vitamin B-12, iron, chlorophyll, GLA fatty acids, and much more. Spirulina has been studied extensively in Russia and China, where research has shown it chelates radiation from the body, as well as provides general protection from radiation toxicity. One study in particular demonstrated how children on a protocol of spirulina after Chernobyl had improved immunity and T-cell counts. Chlorella algae is often listed along with spirulina as an equivalent radiation chelator. However, although chlorella is well-regarded as an excellent heavy metal detoxifier and is also known to reduce chemotherapy side-effects, it has not been demonstrated in research to counter the effects of nuclear radiation.

R-LIPOIC ACID — is a unique, vitamin-like antioxidant that protects the body from free radical damage. Research performed in Russia found that lipoic acid is one of the most effective anti-radiation nutrients available. Research continues to demonstrate that it has many benefits as a super antioxidant and metal chelator, working to repair liver damage, combat radiation sickness, treat diabetes, and protect against free radical damage.

Glutathione (GSH) and N-acetyl-cysteine (NAC) — Glutathione is an internally produced antioxidant that enhances the ability of immune system cells and protects against radiation damage. Studies have also shown that GSH can reduce side effects of chemotherapy, xrays, and alcohol. In addition, it is well-known as a detoxifier of heavy metals, and is extremely useful in the treatment of blood and liver disorders. Supplementing with N-acetyl-cysteine (NAC), a glutathione precursor, stimulates glutathione synthesis. NAC itself is a powerful antioxidant that is effective in detoxifying the liver. Sulphur-containing foods such as cabbage, broccoli, and kale also help the body to produce GSH.

SELENIUM — is a cofactor of glutathione production and activates the antioxidant enzyme glutathione peroxidase, which is believed to protect the body from cancer in large part by increasing white blood cell counts. The largest study performed with selenium demonstrated that people supplementing with selenium developed less prostate, colorectal, and lung cancers. While there are no human studies to support the theory that selenium directly protects against radiation, research performed on rats has demonstrated that selenium decreased death rates in rats who were directly exposed to radiation.

GREEN AND BLACK TEAS — Studies have shown that both green and black teas provide some degree of protection against radiation. Tea catechins seem to absorb and eliminate radioactive isotopes. The polyphenol epigallocatechin gallate (EGCG) derived from green tea has been shown in animal studies to protect from whole-body radiation. Regular black tea exhibited the same anti-radiation effects in several Japanese studies.

BENTONITE CLAY — Has also been recommended for detoxing after radiation exposure, but this is not confirmed by research. Bentonite clay is well-documented in traditional medicine to bind heavy metal toxins and effectively flush them from the body.

Botanical Medicines as Potential Radiation ProtectorsOngoing research on several plants and herbs is demonstrating their potential radioprotective abilities. The natural chemicals, referred to as polyphenols, that are present in various botanicals have been shown to counteract the oxidative stress that is induced by ionizing radiation. They tend to do this either by scavenging radiation-induced free radicals and/or by elevating antioxidant levels in the body.

Many of the botanicals currently being researched have medicinal properties and have been safely used in traditional Chinese and Ayurvedic systems of medicine. These include various plants such as: Podophyllum hexandrum, tinospora cordifolia, phyllanthus amarus, piper longum (pippali) fruit, arctium lappa (burdock root), and zingiber officinale (ginger). The most notable research, however, has been performed on panax ginseng and gingko biloba.

PANAX GINSENG — Studies have successfully demonstrated that treatment with panax ginseng extract aided recovery of cells involved in blood clotting (thrombocytes) and red blood cell counts in blood after radiation exposure. Clinical trials reported that people who took panax ginseng extract for thirty days following exposure to radiation showed a faster recovery rate from injuries to their bone marrow, organs, skin, and blood cells. In animal studies, ginseng extract prevents bone marrow injury and accelerates the recovery of both red and white blood cell counts.

GINGKO BILOBA — Solid research has been performed on extracts of ginkgo biloba, which contain antioxidant compounds that protect cells from free radical damage. Specifically, the results suggest that the gingko biloba extracts prevent cells from undergoing apoptosis (programmed cell death). A study was performed on healthy white blood cells that were then exposed to gamma radiation. Half of the sample was treated with the ginkgo biloba extract and these cells showed protection from the radiation while the untreated cells underwent apoptosis. The study concluded that the extracts of the leaves of the gingko biloba tree may protect human cells from radiation damage.

PECTIN — Ongoing studies are researching pectin as a natural chelating agent. Pectin is a structural polysaccharide (fiber) found in cell walls of plants and fruits. Some studies have demonstrated it to be beneficial for binding and removing radioactive residues from the body. Pectin-rich foods include apples, guavas, plums, gooseberries, and citrus fruits.

Caveat, re: Iodine — While Dr. Joseph Mercola recognizes that optimal amounts of dietary iodine are important to nourish the thyroid, he warns about the risk of getting too much iodine: “Taking too much iodine may lead to subclinical hypothyroidism, which occurs when your thyroid produces too little thyroid hormone. It’s an ironic association, since hypothyroidism is often linked to iodine deficiency, But research published in the American Journal of Clinical Nutrition revealed that study participants taking relatively higher doses of supplemental iodine — 400 micrograms a day and more — paradoxically began developing subclinical hypothyroidism.”

Dr. Mercola also points to a major culprit in the epidemic of iodine deficiency in North Americans today:bromine exposure. “When you ingest or absorb bromine (found in baked goods, plastics, soft drinks, medications, pesticides and more), it displaces iodine, and this iodine deficiency leads to an increased risk for cancer of the breast, thyroid gland, ovary and prostate — cancers that we see at alarmingly high rates today.”

Food IS MedicineBuckwheat is an important food to include, according to researchers. Buckwheat is high in the bioflavonoid rutin, and research supports its protective effects against radiation, and stimulating new bone marrow production. Also important to include in the diet are dried beans, especially lentils, which have been shown to reverse DNA damage caused by radiation. Incorporating medicinal mushrooms such as reishi and chaga mushrooms into the diet can also protect from radiation-induced, cancers according to research.

Much of the damage caused by radiation can be attributed to a high level of acidity and the inflammation that results in several diseases. Consuming alkalizing foods can have a multitude of benefits, and is protective against radiation-induced illnesses. Alkalinizing foods include whole grains, fruits, leafy green vegetables, essential fatty acids, lean proteins, etc, whereas acidifying foods are processed foods, refined carbohydrates, and sugar.

Black death was not spread by rat fleas, say researchers

Black death

Black death researchers extracted plague DNA from 14th century skulls found in east London. Photograph: Philip Toscano/PA

Archaeologists and forensic scientists who have examined 25 skeletons unearthed in the Clerkenwell area of London a year ago believe they have uncovered the truth about the nature of the Black Death that ravaged Britain and Europe in the mid-14th century.

Analysis of the bodies and of wills registered in London at the time has cast doubt on “facts” that every schoolchild has learned for decades: that the epidemic was caused by a highly contagious strain spread by the fleas on rats.

Now evidence taken from the human remains found in Charterhouse Square, to the north of the City of London, during excavations carried out as part of the construction of the Crossrail train line, have suggested a different cause: only an airborne infection could have spread so fast and killed so quickly.

The Black Death arrived in Britain from central Asia in the autumn of 1348 and by late spring the following year it had killed six out of every 10 people in London. Such a rate of destruction would kill five million now. By extracting the DNA of the disease bacterium, Yersinia pestis, from the largest teeth in some of the skulls retrieved from the square, the scientists were able to compare the strain of bubonic plague preserved there with that which was recently responsible for killing 60 people in Madagascar. To their surprise, the 14th-century strain, the cause of the most lethal catastrophe in recorded history, was no more virulent than today’s disease. The DNA codes were an almost perfect match.

Breaking News: FDA’s Sneak Attempt to Ban Another B Vitamin

March 11, 2014

Vitamins Close-upYou can’t live without this vitamin. But the FDA wants to reserve the natural form for monopoly drug companies, leaving only the synthetic form for supplements. Urgent Action Alert!

 

The FDA has just released a new 109-page guidance on the revision of nutrition and supplement labels. (You can read more about the implications of the new labeling rules in our other article this week.)

 

On page 69, the agency slipped in two little paragraphs that could risk the health of millions of people who desperately need folate. It’s a sneak attack so quiet and unobtrusive that few people will even realize it’s there.

 

According to the guidance, the word “folate” will be banned from the Supplement Fact labels—only the term “folic acid” will be allowed.

 

Folate is the naturally occurring form of the water-soluble vitamin B9. It is found in foods such as black-eyed peas, chickpeas and other beans, lentils, spinach, turnip greens, asparagus, avocado, and broccoli, but is also available as a supplement.

 

The human body needs folate to synthesize and repair its DNA. It’s especially important during the kind of rapid cell division and growth seen in infancy and pregnancy. Children and adults both require folate to produce healthy red blood cells and prevent anemia among many other vital functions.

 

Folic acid, on the other hand, is synthetically produced, and refers to just one member of the folate group: pteroylmonoglutamic acid. While folic acid occurs only rarely in whole foods, it’s extremely stable, which is why it’s widely used in dietary supplements and to fortify processed foods.

 

The important thing to remember is that folic acid is not itself biologically active, though for most people the liver can convert it to the folate we need. Most, however, does not mean all. It’s estimated that 30% to 40% of the population can’t efficiently convert synthetic folic acid into folate.

 

In other words, about a third of the human population has two potential problems: a deficiency in folate (because it is hard to get enough from a diet full of processed foods), and possibly even an excess of folic acid (because their body can’t metabolize what could become an overabundance of folic acid present in “fortified” foods):

 

  • According to Dr. Jonathan V. Wright, folate deficiency is one of the most dangerous medical conditions, leading to Alzheimer’s and other brain diseases. If pregnant women are deficient in it, it can also lead to spina bifida and other neural tube birth defects in their children.

 

 

Note that the FDA is not exactly banning the inclusion of folate and requiring the inclusion of folic acid in supplements. As usual, it is playing a much more subtle insider’s game. It is simply banning supplement producers from using the word folate on their labels and conversely only allowing the word folic acid on their labels. But it would of course be fraudulent to put folic acid on your label and then use something else. The FDA understands that perfectly.

 

So on what grounds is the agency banning the use of the word folate on the label? Believe it or not, it is arguing that folate can only be found in “conventional” (whole or minimally processed) foods.

 

Before we examine this absurd claim, we must first explain that limiting a folate claim to food would not prevent drug companies from becoming the only source of folate outside of food. Drug companies don’t care what a chemical is called so long as they can create a high priced monopoly in it. Ironically, the FDA’s position that folate can only be used to describe what is in food would still turn folate over to the drug companies—so long as supplement labels can only use the term folic acid.

 

So what about the agency’s assertion that “folate” can only be found in food? “Folate” is actually a term for a whole B vitamin group. The term “folate” we see on dietary supplement labels refers to “dietary folates,” members of the folate group that can be naturally found in foods. Folinic acid (5-FTHF), calcium methylfolate, and various other tetrahydrofolates can be found in dietary supplements. Many brands feature dietary folate.[1] It would be completely inaccurate and misleading to refer to these dietary folates as “folic acid.” Legally, it would be fraudulent.

 

Why did the FDA do this? One can only guess. But it would not be surprising if it eventually turns out to be a blatant attempt to reserve for drug companies the use of dietary folates. After all, B vitamins are not only essential for life. They are also proven therapeutic agents. Drug company research programs have been coming up short for years; new drug therapeutic agents are in very short supply.

 

Moreover, the drug company Merck already holds patents on Metafolin, which the body recognizes as a bioavailable dietary folate. Metafolin is licensed by dietary supplement companies for some of their products.

 

If, according to FDA “logic,” dietary supplements can’t contain folate like Metafolin, it would only be available from whole foods…or drugs, and only from drugs in higher doses. Since Merck would have exclusivity for a Metafolin “drug,” our guess is that they would make billions. And other forms of patentable folate could then follow.

 

Sound unlikely? It’s not—both forms of fish oil and vitamin D have already been turned into patented drugs. Imagine if competition from supplemental forms of fish oil or D could be wiped out at one stroke by saying no supplement label could use the term!
