Outlawing drugs like marijuana censors science, researchers say

The outlawing of drugs such as cannabis, magic mushrooms and other psychoactive substances amounts to scientific censorship and is hampering research into potentially important medicinal uses, leading scientists argued on Wednesday. Laws and international conventions dating back to the 1960s have set back research in key areas such as consciousness by decades, they argued in the journal Nature Reviews Neuroscience. “The decision to outlaw these drugs was based on their perceived dangers, but in many cases the harms have been overstated,” said David Nutt, a professor of neuropsychopharmacology at Imperial College London. In a statement accompanying the Nature Reviews paper, he said the laws amounted “to the worst case of scientific censorship since the Catholic Church banned the works of Copernicus and Galileo”. “The laws have never been updated despite scientific advances and growing evidence that many of these drugs are relatively safe. And there appears to be no way for the international community to make such changes,” he said. “This hindering of research and therapy is motivated by politics, not science.” Nutt and Leslie King, both former British government drugs advisers, and co-author David Nichols of the University of North Carolina, called for the use of psychoactive drugs in research to be exempted from severe restrictions. “If we adopted a more rational approach to drug regulation, it would empower researchers to make advances in the study of consciousness and brain mechanisms of psychosis, and could lead to major treatment innovations in areas such as depression and PTSD,” Nutt said. Nutt was sacked as a government adviser in 2009 after publicly criticizing the government for ignoring scientific advice on cannabis and ecstasy. He has conducted a small human trial using psilocybin, the psychedelic ingredient in magic mushrooms. His study, using volunteers, suggested the drug had the potential to alleviate severe forms of depression in people who did not respond to other treatments. But in April, Nutt said his plans to conduct the first full clinical trial to explore psilocybin as a treatment had stalled because of stringent rules on the use of illegal drugs in research. The scientists said their call for reform had been endorsed by the British Neuroscience Association and the British Association for Psychopharmacology.source : http://www.foxnews.com/health/2013/06/12/outlawing-drugs-like-marijuana-censors-science-researchers-say/

WHO: MERS coronavirus has potential to cause pandemic

The World Health Organization on Monday urged health workers around the world to be on the alert for symptoms of the deadly Middle East respiratory syndrome coronavirus (MERS), which has the potential to circle the globe and cause a pandemic. The United Nations agency, which issued new, long-awaited guidance to countries on influenza pandemics, said the world was also in the same “alert phase” for two human strains of bird flu - H5N1, which emerged a decade ago, and H7N9, first detected in China in March. “We are trying to find out as much as we can and we are concerned about these (three) viruses,” Andrew Harper, WHO special adviser for health security and environment, told a news briefing on its new scale for pandemic risk. The interim guidance, to be finalized later this year, incorporates lessons from the 2009/2010 pandemic of H1N1 swine flu, which caused an estimated 200,000 deaths, roughly in line with annual seasonal flu. Having been adjusted to include the notion of severity when assessing risk, the new scale has just four phases against six previously and is intended to give countries more flexibility in judging local risks. “International concern about these infections is high, because it is possible for this virus to move around the world. There have been now several examples where the virus has moved from one country to another through travelers,” the WHO said of MERS, which causes coughing, fever and pneumonia. Travelers have carried the virus to Britain, France, Germany and Italy. Infected people have also been found in Jordan, Qatar, Tunisia and the United Arab Emirates. “Consequently, all countries in the world need to ensure that their healthcare workers are aware of the virus and the disease it can cause and that, when unexplained cases of pneumonia are identified, MERS-CoV should be considered.” MERS-coronavirus, a distant relative of SARS that emerged in Saudi Arabia last year, has been confirmed in 55 people worldwide, killing 31 of them. Forty cases occurred in Saudi Arabia, many in a hospital in the eastern province of al-Ahsa. “The overall number of cases is limited but the virus causes death in about 60 percent of patients,” the WHO said, reporting on a week-long mission of international experts to Saudi Arabia that ended on Sunday. “So far, about 75 percent of the cases in the Kingdom of Saudi Arabia have been in men and most have occurred in people with one or more major chronic conditions.” But the source of the MERS virus remained unknown, it said. Clusters of cases have occurred in families and health facilities, indicating a limited capacity to spread among people in close contact with an infected person, it said. All countries in the Middle East should urgently intensify disease surveillance to detect any MERS infections, it said. The WHO has not yet drawn up advice for Travelers ahead of the annual haj pilgrimage in October, which draws millions of Muslims to Saudi Arabia.source : http://www.foxnews.com/health/2013/06/10/who-mers-coronavirus-has-potential-to-cause-pandemic/

Airport therapy dogs take the stress out of travel

There’s a new breed of airport dog. They aren’t looking for drugs or bombs — they are looking for people who need a buddy, a belly to rub or a paw to shake. “His job is to be touched,” volunteer Kyra Hubis said about Henry James, her 5-year-old golden retriever that works a few hours a week at the San Jose airport. “I am just standing there with him. They are talking to him. If I need to answer for him, I do. But I am at the end of his leash, he’s not at the end of mine.” Mineta San Jose International Airport is widely credited with introducing the first airport therapy dog in the days after Sept. 11, 2001, when flights were grounded, passengers were stranded and reaching friends and relatives in the East was nearly impossible. Passengers were anxious and afraid. Enter Orion, owned by a volunteer airport chaplain who got permission to bring the dog to work. He made such a difference that San Jose formalized the program and now has nine dogs. Miami International Airport got onboard the program with one and Los Angeles International Airport has 30 and is hoping to expand its program. The dogs are intended to take the stress out of travel — the crowds, long lines and terrorism concerns. You never know why people are flying, said Heidi Huebner, director of volunteers at LAX, which launched Pets Unstressing Passengers (PUPs) in April. Travelers might be in town for a vacation, a funeral, to visit a sick family member or to attend a business meeting. “You can literally feel the stress levels drop, people start smiling, strangers start talking to each other and everybody walks away feeling really, really good,” Huebner said. Dogs have to be healthy, skilled, stable, well-mannered and able to work on a slack 4-foot leash, said Billie Smith, executive director of Wyoming-based Therapy Dogs, Inc., which certifies the LAX animals. They have to be comfortable with crowds, sounds, smells — and they need to pass through security like all airport workers. Handlers are taught to watch for people who fear or dislike dogs or those who might have allergies. In most cases, people approach the dogs, identifiable by the vests or bandannas they wear. Los Angeles’ dogs, which are featured on trading cards, are as varied as its airport passengers. There’s a long-haired Dalmatian, a Lab-pointer mix, a field spaniel, a poodle, three Australian Labradoodles, a Doberman and a 150-pound Irish wolfhound named Finn who has two tricks. “He looks you in the eye and lays down on the job,” said owner Brian Valente. “When I’m around Finn, it makes me feel like things are OK. When Finn’s around other people, they are OK. It’s almost instant, even if just for a moment,” Valente said. Miami’s sole dog, Casey, a 4-year-old golden retriever, is a star. She has her own website, fan mail, business cards and a role on “Airport 24/7: Miami,” a weekly reality show on the Travel Channel. “Casey is so pure and genuine,” explained Dickie Davis, director of terminal operations and customer service. “She’s not asking for anything or selling anything. She is just a love magnet.” When Claudia McCaskill’s family recently flew home from vacation in Brazil she requested Casey meet the plane to greet her 5-year-old daughter, Carina, who is autistic. She knew Carina would be low on energy and patience and they still had a 2.5-hour drive home to St. Lucie. Casey and handler Liz Miller were there with a gift basket and Carina fell in love with the dog. “Thank you for visiting us at the airport so I would be happy,” Carina said in a video the family made for Casey. Now Carina wants to go back and see Casey again. “I can’t say how much we appreciate what they did for us. It not only helped our daughter, but us too,” McCaskill said. Despite all the smiles, there are also hard moments. Before departing from San Jose, a soldier kneeled down and told Henry James: “OK, buddy, you take care of the house while I am gone,” Hubis said. A woman who said her husband of 40 years told her he wanted a divorce that morning wept on Henry’s shoulder. “He just sat there,” Hubis said. “He knew. He can feel.”source : http://www.foxnews.com/health/2013/06/10/airport-therapy-dogs-take-stress-out-travel/

New factor to control oncogene-induced senescence discovered

The researchers who participated in this international research are: Marta Cascante and Vitaly Selivanov, from the Department of Biochemistry and Molecular Biology of the Faculty of Biology of the UB and the Institute of Biomedicine of the University of Barcelona (IBUB), affiliated to the campus of International excellence Barcelona Knowledge Campus (BKC) ; Liang Zheng and Eyal Gottlieb, from Beatson Institute for Cancer Research (Scotland), and Joanna Kaplon and Daniel S. Peeper, from the Netherlands Cancer Institute, among other experts. Cellular senescence: a ‘brake’ to cell division Cellular senescence, formally described more than four decades ago by Paul Moorhead and Leonard Hayflick, is a tumour suppression mechanism which limits cell’s ability to proliferate. This process works as a ‘brake’ for tumour genesis and can be an answer to several factors (oncogene, oxidative stress, telomere alterations, etc.) Professor Marta Cascante, head of the Consolidated Research Group on Integrative Systems Biology, Metabolomics and Cancer of the UB honoured with the ICREA Academia Award 2010, explains that "as a response to an oncogene mutation, cell can activate its protection mechanisms and get into a phase so-called ‘oncogene-induced senescence’ which acts as a key tumour suppressive mechanism. …
