While Mexico grapples with relentless drug-related violence, a group of Mexican scientists is working on a vaccine that could reduce addiction to one of the world’s most notorious narcotics: heroin.
Researchers at the country’s National Institute of Psychiatry say they have successfully tested the vaccine on mice and are preparing to test it on humans.
The vaccine, which has been patented in the United States, works by making the body resistant to the effects of heroin, so users would no longer get a rush of pleasure when they smoke or inject it.
“It would be a vaccine for people who are serious addicts, who have not had success with other treatments and decide to use this application to get away from drugs,” the institute’s director Maria Elena Medina said Thursday.
Scientists worldwide have been searching for drug addiction vaccines for several years, but none have yet been fully developed and released on the market.
One group at the U.S. National Institute on Drug Abuse has reported significant progress in a vaccine for cocaine.
However, the Mexican scientists appear to be close to making a breakthrough on a heroin vaccine and have received funds from the U.S. institute as well as the Mexican government.
During the tests, mice were given access to deposits of heroin over an extended period of time. Those given the vaccine showed a huge drop in heroin consumption, giving the institute hope that it could also work on people, Medina said.
Kim Janda, a scientist working on his own narcotics vaccines at the Scripps Research Institute in La Jolla, California, said that based on some earlier research papers he had read, the Mexican vaccine could function but with some shortcomings.
“It could be reasonably effective but maybe too general and affect too many different types of opioids as well as heroin,” Janda said.
Mexico, a major drug producing and transit country for drugs smuggled into the United States, has a growing drug addiction problem. Health Secretary Jose Cordoba recently said the country now has some 450,000 hard drug addicts, particularly along the trafficking corridors of the U.S. border.
Mexican gangsters grow opium poppies in the Sierra Madre mountains and convert them into heroin known as Black Tar and Mexican Mud, which are smuggled over the Rio Grande.
Every year, the heroin trade provides billions of dollars to gangs like the Sinaloa Cartel and the Zetas. Since 2006, cartel violence has claimed the lives of over 47,000 people in Mexico.

Vaccines For Everything: Researchers Now On Brink Of Developing Salmonella Jab

The vaccine industry is currently hard at work trying to churn out a vaccine for salmonella, a typically food borne pathogen that thrives on factory farms and in other unsanitary settings. CBS 13 News in Sacramento reports that researchers from the University of California, Davis, have been tasked with developing a vaccine that supposedly prevents salmonella, which these researchers say they are on the verge of completing in the very near future.
Rather than attempt to address the root causes of salmonella, which include filthy animal living conditions on industrial farms and the overuse of synthetic antibiotics in conventional livestock, just to name a few, mainstream science is busy concocting new ways to jab people with toxic chemical cocktails that could permanently injure them.
Funded by a grant from the National Institutes of Health, Stephen McSorley and his team of international researchers believe that by closely studying the immune response to infection in mice, they will be able to arrive at a solid vaccine protocol for “curing” salmonella. And their findings thus far, which were recently published in the journal Proceedings of the National Academy of Sciences, seem to indicate that the project is moving forward as planned.
Not surprisingly, Big Pharma is behind this ludicrous endeavor to develop a vaccine for an illness that is largely preventable through improved hygiene, small-scale agriculture, and naturally-boosted human immunity. Drug giant GlaxoSmithKline (GSK) and the Novartis Vaccines Institute for Global Health are both collaborators on the project, which is expected to soon move into human clinical trials (http://www.foodsafetynews.com/2012/02/a-vaccine-against-salmonella/).
The development of this new salmonella vaccine appears to also align directly with the vision of a group of researchers in the U.K. who last summer called for the development of 20 new vaccines in the next decade. Their paper, which was published in the journal Lancet, seeks funding for the development of vaccines “beyond classic infections,” including for things like diabetes, degenerative diseases, and even cancer (http://www.bbc.co.uk/news/health-13714224).
So by the looks of it, there could soon be vaccines for virtually everything — a headache, an upset stomach, a paper cut, you name it. Anything mainstream medicine can identify that is a consequence of a underlying condition rather than a cause of it is open game for vaccine development because there is a whole lot of money to be made utilizing this approach to so-called medicine.

Arsenic Found In Infant Formula, Cereal Bars

Is arsenic in your breakfast? A new study suggests that might just be what you – or your children – are having each morning.
Researchers at Dartmouth College already knew that rice can be a major source of inorganic arsenic. This includes rice products, such as organic brown rice syrup, an alternative sweetener to high fructose corn syrup. Exposure to high levels of inorganic arsenic over time has been tied to increased risk for cancer.
For the study – published in the Feb. 16 issue of Environmental Health Perspectives – the researchers investigated levels of arsenic in commercially available brown rice syrups, and in products containing the syrups, including infant formula, cereal and energy bars, and high energy foods used by endurance athletes.
What did they find? Surprising levels of arsenic in these products containing organic brown rice syrup.
Out of 17 infant formulas tested, 15 did not contain organic brown rice syrups – and had relatively low levels of arsenic. As for the two formulas that listed organic brown rice syrup as the primary ingredient – those contained 20 times as much arsenic as ones without the rice ingredient. One had a total arsenic concentration that was six times the federal limit of 10 parts per billion (ppb) for total arsenic in bottled or public drinking water.
Out of 29 cereal or energy bars tested, 22 contained at least one rice product in the top five ingredients. The seven that didn’t had the lowest levels of arsenic, while those that did contained levels of arsenic ranging from 23 to 128 ppb. The energy shots contained between 84 and 171 ppb arsenic.
Study author Dr. Brian Jackson, an environmental chemistry researcher at Dartmouth’s Superfund Research Program, told Consumer Reports, ” I would certainly advise parents who are concerned about their children’s exposure to arsenic not to feed them formula where brown rice syrup is the main ingredient.”
There are currently no U.S. regulations for arsenic in food. But the new study shows some food products bring significant amounts of arsenic to an individual’s diet, so researchers conclude “there is an urgent need for regulatory limits on [arsenic] in food.”
This study isn’t the first to put arsenic in the spotlight. Levels of arsenic have previously been found in apple and grape juice.

Researchers from the Colorado Cancer Center reporting in the prestigious journalCarcinogenesis explain the unique mechanism exerted by grape seed extract to destroy cancer cells that target the head and neck. More than half a million people worldwide will fall victim to squamous cell carcinoma involving the head and neck, and 12,000 will die in the US alone. In an experimental model using mice, scientists have found that grape seed extract triggers DNA damage in the cancer cells and inhibits the necessary repair mechanism used by the cells to regenerate and multiply.
Grape seed extract has been the subject of multiple studies that demonstrate the polyphenols ability to support brain health, improve cognition and lower the risk of dementia. Regular consumption of red grapes or supplementation with grape seed extract is now found to be an important ally in the war against cancer. Grape seed extract lowers the growth rate of certain cancers by up to 67%.

Invisibility’s Next Frontier: Scientists Cloak 3-D Objects

“What would you do with the power of invisibility? Do you think you could resist being bad?” –KTRN
After five years of steady progress, scientists are now edging closer and closer to mastering real-world invisibility.
Sure, researchers have already made marked strides toward making objects unseeable. But much of the work was more like mimicry: Meta-materials that bent light around an object to conceal it, but only worked in two dimensions. Or a device that played tricks on the eye, by harnessing the mirage effect to make objects behind it “disappear.”
Now, a team of researchers have taken an incredible leap forward. They’ve successfully made a 3-D object disappear.
A group of scientists at the University of Texas at Austin have figured out how to “cloak a three-dimensional object standing in free space.” That means the object is invisible, from any angle of observation.
“This object’s invisibility is independent of where the observer is,” Professor Andrea Alu, the study’s co-author, tells Danger Room. “So you’d walk right around it, and never see it.”
Of course, the Pentagon’s been hot on the invisibility trail for years, and for obvious reasons. Invisibility would make plenty of covert operations way easier to execute, not to mention safer for U.S. personnel and deadlier for their foes.
Already, scientists have taken impressive steps forward, and at a freakily fast pace. Researchers in the U.K. have harnessed the mirage effect to mask objects placed behind a device, and Army-backed research is making impressive strides using meta-materials to bend light around objects. Just a few weeks ago, the world’s mind was collectively blown when Pentagon-funded scientists managed to cloak an actual event.
The latest research, published this week in the New Journal of Physics, uses “plasmonic meta-materials” to make an 18-inch cylindrical tube invisible. Put simply: An everyday object is visible because light rays bound off it, hitting our eyes and allowing our brains to process the info. Different cloaking techniques take different approaches to messing with those light rays.

Children Who Take Antibiotics More Prone to Contracting ‘Superbugs’

A group of Canadian researchers has found a link between taking antibiotics and a higher likelihood of harboring deadly “superbugs” like methicillin-resistant Staphylococcus aureus (MRSA), which kills tens of thousands of people every year. Published in the journal Archives of Pediatrics & Adolescent Medicine, the breakthrough study found that children who take at least one antibiotic are three times as likely to develop MRSA than children who take no antibiotics, while children who take four or more antibiotics are 18 times more likely to develop MRSA.
It is commonly believed that superbugs are found only in dirty, drug-ridden hospitals, where patients end up contracting it from contaminated surfaces and surgical instruments. But according to the study, community-acquired MRSA, which means it is contracted outside the hospital setting in the general public, is becoming a major health problem, and one that appears clearly linked to overuse of antibiotics.
For their study, a research team from McGill University in Montreal examined antibiotic prescription data from over 400 doctors’ offices across the UK. Since studies had previously observed in adults a link between antibiotics and superbugs, the team this time focused primarily on children who were diagnosed with MRSA between 1994 and 1997.
Among 297 children who tested positive for MRSA, 53 percent of them had been prescribed an antibiotic between 30 and 180 days prior to their diagnosis. Only 14 percent of children who visited the same doctors, but that did not have MRSA, had taken any antibiotics at all. After adjusting for various outside factors, the team determined a three-fold and eighteen-fold increased risk of contracting a superbug when taking either one, or four or more, antibiotics, respectively.
“This is an intriguing observation that we expect will generate some research into the mechanism of MRSA development,” said Samy Suissa, lead author of the study. “Parents should freely discuss with their physician if they feel that antibiotics may be overprescribed.”

Researchers Find Genes Linked To Most Common Form of Breast Cancer

By Stephen Adams
The genes could lead to new ways of diagnosing and treating hormonal breast cancer, also known as oestrogen receptor positive breast cancer, which is responsible for four out of five cases, or 36,000 a year in Britain.
In particular, they found one gene which appears to drive the growth of tumours.
The scientists, from the Breakthrough Breast Cancer Research Centre at The Institute of Cancer Research (ICR) in London, said the discovery could in the future help patients whose breast cancers do not respond to drugs like tamoxifen.
They located the genes – named C6ORF96, C6ORF97 and C6ORF211 – in a very well studied part of the human genome, next to the oestrogen receptor gene, which is the main driver of hormonal breast cancer.
Dr Anita Dunbier, lead author of the study, which is published in the journal PLoS Genetics, said: “This is a surprising discovery. We found these genes in a place we thought we knew a lot about – it is like finding gold in Trafalgar Square.
Energy Saving Light Bulbs Dangerous Due to Mercury

Daily Mail
By: David Derbyshire
Energy-saving light bulbs were at the centre of a fresh health scare last night after researchers claimed they can release potentially harmful amounts of mercury if broken.
Levels of toxic vapour around smashed eco-bulbs were up to 20 times higher than the safe guideline limit for an indoor area, the study said.
It added that broken bulbs posed a potential health risk to pregnant women, babies and small children.
The concerns surround ‘compact fluorescent lamps’ (CFLs), the most common type of eco-bulb in Britain, which are mini-versions of the strip lights found in offices.
The European Union is phasing out the traditional ‘incandescent bulbs’ used for more than 120 years and is forcing people to switch to low-energy alternatives to meet its climate change targets.
A CFL uses a fifth of the energy of a conventional bulb and can save £7 a year in bills. However, critics complain that CFLs’ light is harsh and flickery. Medical charities say they can trigger epileptic fits, migraines and skin rashes and have called for an ‘opt out’ for vulnerable people.
Incandescent bulbs do not contain mercury, along with other variants of energy-saving lights, such as LEDs and halogen bulbs. The study, for Germany’s Federal Environment Agency, tested a ‘worst case’ scenario using two CFLs, one containing 2 milligrams of mercury and the other 5 milligrams. Neither lamp had a protective casing and both were broken when hot.
Scientists at the Fraunhofer Wilhelm Klauditz Institute found that they released around 7 micrograms (there are 1,000 micrograms in a milligram) per cubic metre of air.The official guideline limit is 0.35 micrograms per cubic metre.
Federal Environment Agency president Jochen Flasbarth said: ‘The presence of mercury is the downside to energy-saving lamps. We need a lamp technology that can prevent mercury pollution soon.
‘The positive and necessary energy savings of up to 80 per cent as compared with light bulbs must go hand in hand with a safe product that poses no risks to health.’
During tests the German government agency’s researchers were alarmed to discover that some bulbs had no protective cover and broke when hot.
High levels of mercury were measured at floor level up to five hours after the bulbs failed.
A spokesman for the agency said: ‘Children and expectant mothers should keep away from burst energy-saving lamps.
‘For children’s rooms and other areas at higher risk of lamp breakage, we recommend the use of energy-saving lamps that are protected against breakage.’ However, the UK Government insisted the CFL bulbs were safe – and that the risk from a one-off exposure was minimal.
The Health Protection Agency says a broken CFL is unlikely to cause health problems. However, it advises people to ventilate a room where a light has smashed and evacuate it for 15 minutes.
Householders are also advised to wear protective gloves while wiping the area of the break with a damp cloth and picking up fragments of glass. The cloth and glass should be placed in a plastic bag and sealed.
CFLs are not supposed to be put in the dustbin, whether broken or intact, but taken as hazardous waste to a recycling centre.
A spokesman for the Department for Environment, Food and Rural Affairs said: ‘Guidance from the Health Protection Agency makes it clear that the mercury contained in low energy bulbs does not pose a health risk to anyone immediately exposed, should one be broken.’
Friends of the Earth said the switch to low-energy bulbs would reduce exposure to mercury from coal-fired power stations.

Yale Researchers Find Key Depression Gene
October 19, 2010 by admin

AOL Health
By: Catherine Donaldson-Evans
Researchers at Yale University say they’ve identified a new gene that seems to trigger depression.
The scientists say the gene, MKP-1, might be a key contributor in the development of clinical depression.
“This could be a primary cause, or at least a major contributing factor, to the signaling abnormalities that lead to depression,” study lead author Ronald S. Duman, a professor of psychiatry and pharmacology at Yale, said in a statement.
Duman and his colleagues did genome scans of the brain tissue of 21 deceased people who had been diagnosed with depression and compared them to the genes of 18 people who hadn’t been diagnosed with the condition.
They found that one gene, MKP-1, increased more than twofold in the brains of people who were depressed. That gene blocks a molecular pathway neurons need to survive and function properly, which, when rendered inactive, has been linked to depression and other disorders.
The team also discovered that when MKP-1 is impaired in mice, the mice become resistant to stress, but when it’s activated, they show signs of depression.
University of Pennsylvania psychiatrist Dr. Christos Ballas said the study is flawed.
“You can’t say this is a gene for depression because it’s a gene for only one kind of depression,” he told AOL Health. “It’s a gene for a specific description of depression.”
Ballas said there is evidence that depression is in part genetic, but there are other factors involved in the illness.
“Certainly, there’s probably a common genetic component that makes us susceptible to depression,” he said. “But the problem is the effect of that gene is probably overwhelmed by the effect of everything else that happens in our life, including other genes.”
The findings were published October 17 in the journal Nature Medicine. Researchers say they may inspire a new class of antidepressants.
Doctors and scientists have had trouble pinpointing the causes of depression, which costs the United States $100 billion a year and affects nearly 16 percent of Americans.
Numerous physiological factors are believed to contribute to major depressive disorder, whose symptoms can vary from person to person. Patients given prescription antidepressants often respond differently to the drugs, and up to 40 percent don’t respond at all.
Ballas said that while the Yale research and other studies on depression genes are helpful, such findings aren’t revolutionary or applicable to all those who suffer from the condition.
“It is in no way generalizable to everybody,” Ballas said. “It’s much more useful to give a drug to treat the symptom than finding a gene for this one tiny aspect of depression. The more of these little genetic findings we get that don’t have any immediate usefulness, the more we minimize the environmental impact.”
