LOS ANGELES, July 18 (Xinhua) -- At least 70 genetic mutations may be involved in the formation of colon cancer, far more than scientists previously thought, a new study suggests.The study by researchers at University of Texas (UT) Southwestern Medical Center contradicts previous thinking that only a few mutated genes may play a role in the development of colon cancer."The ways we've been treating patients up to now is to just go after one target when we should be going after three to four different pathways simultaneously," said Dr. Jerry W. Shay, vice chairman and professor of cell biology at UT Southwestern.The new study identified 65 candidate genes and at least five passenger genes whose mutations play significant roles in cancer development. Inactivating the function of any of these tumor- suppressing genes led to a key step in cancer development called anchorage-independent growth, meaning cells piled up on top of each other rather than aligning neatly.According to previous studies, there were 151 candidate genes and that mutations in just eight to 15 of them would lead to cancer. There were 700 other genes classified as passenger genes whose mutations were incidental to cancer growth.Current cancer treatments target just one or two known cancer- driver genes. While patients may get transient tumor burden reduction, almost universally tumor growth returns."Those numbers are dead wrong," Dr. Shay said, suggesting a new approach to colon cancer treatments targeting multiple genes and pathways simultaneously.The next step is further research to classify more accurately which genes drive cancer and which are merely passengers, the researchers said.Study findings were published in the July 2011 Cancer Research (Priority Reports).

BERLIN, June 5 (Xinhua) -- German authority said on Sunday that bean sprouts might be the "most convincing" source for the E. coli outbreak which has killed 22 people and infected more than 2,000 in the Europe.Gert Lindemann, Agriculture Minister of the state Lower Saxony, told reporters in a press conference that restaurants and food outlets where the cases of E. coli had been reported all had received shipments of the particular bean sprouts.A related company in the Uelzen region has been shut down and its products have been recalled, he said."It is the most convincing... source for the E. coli outbreak," Lindemann said. Although a conclusive laboratory analysis will not come out until Monday, current indications were strong enough to issue a public warning, he said.Authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries - all of whom had once traveled in northern Germany. More than 600 of those infected have developed Hemolytic Uremic Syndrome (HUS), a potentially deadly complication attacking the kidneys.The source of E.coli was first thought to be the cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by Laboratory tests in Hamburg on Tuesday.

VANCOUVER, Sept. 18 (Xinhua) -- At the fourth International Qigong Tournament and Exchange currently going on in Vancouver, many of the competitors spoke Sunday of how the practice had improved their lives after being able to overcome the complications of illness and injury.While many of the more than 300 competitors in the eight-day tournament were out to demonstrate they were among the best practitioners in the world, others were clearly happy to be competing after previously living with various ailments that had affected their mobility and overall way of life."I've been very ill," said competitor Felicia Kazmer of the New Jersey-based U.S. Health Qigong Association. "I have Lyme disease and infections. I was out on medical for six months last year and through the practice of Qigong, and especially the intense practice because I knew we were coming to the tournament, I am feeling better than I have in years and years. I know that this has opened the meridians and allowed the qi to flow and it's worked better than any drug."While Qigong has been practiced in China for centuries, it is relatively new to the outside world. It is for this reason that after holding the biennial International Qigong Tournament and Exchange in China on the first three occasions, the event was moved abroad for the first time to help increase its awareness and growing popularity.Altogether, 44 Health Qigong teams are in Canada from 25 nations and regions for the tournament.Philip Moot, a 26-year-old from The Hague, was attending the tournament for a second time after taking in the last competition in Shanghai in 2009. Now studying Chinese acupuncture, the Dutchman said he took up Qigong after suffering from Pfieffer, a glandular fever that is a fatigue illness."I was always tired and when I woke up in the morning I felt already tired. Then I started with Qigong and exercises and it improved my health enormously. I'm doing it now, I think four years, and it made me stronger. The tiredness is gone."Moot said the more you put into Qigong, a series of movements and postures that focuses on regulated breathing techniques, focused meditation and self-massage, the more a person will get out of it.He compared the practice to charging up a battery and added he had now turned his parents on to Qigong, as well as a friend's father who is battling cancer. "It's helping him also to relieve the pain a little and not to think constantly of this disease."According to various clinical studies, the regular practice of Qigong has shown to be beneficial in reducing stress, better balance, lowering blood pressure, enhancing the immune system, improving sleep patterns, as well as improved cardiovascular, respiratory, circulatory and digestive functions, among many others.Depending on who you talk to, the benefits of Health Qigong means different things to different people, according to practitioner Susan Gallin. The New Jersey nurse took up the practice 18 months ago after undergoing knee surgery."But after the surgery my knee was never back to normal. So someone suggested to take Qigong," she said. "And I started taking it and it was amazing. I guess maybe after a couple of months my knee started to feel better and I'm not 100 per cent right now, but I do really well. I can squat down, things I couldn't do before the surgery."Working in the medical industry, Gallin said she was at odds with the western mentality of taking pills for everything. She felt hospitals should offer more wellness programs than they do."Some of the hospitals in the United States offer such things that include this type of alternative medicine, but I don't think it's enough. Some of the bigger pharmaceutical companies offer wellness programs before the hospitals and you would think we are in a healthcare system that they would offer a wellness (program), try to keep you well so you don't get sick. I know for myself I always try to do whatever I can before I take a pill."Reg Carter knows what it is like to endure a steady diet of pills after having to take anti-inflammatories and painkillers for problems with his joints. For the past two years the native Derby, England, has been practicing Qigong and was in Vancouver as part of the British team taking part."I had shoulder injuries, a broken collarbone, arthritis of several joints, elbows, my hands, fingers and the mobility has improved considerably since I've been doing the Qigong. The mobility has improved and also with the strengthening through the lower body and legs. The back injuries has improved. I don't get so much pain and I find I can move about a lot more fluidly," he said."I just feel like I've had a lot more life balance. I feel a lot more calmer. My sleep pattern's improved. I don't get angry so often, and if I do I find that I can get to grips with it and keep a lot calmer."Toronto resident Karen Widmer has never endured the pain suffered by Carter, but credits the energy of Qigong in aiding the recovery of a broken wrist she suffered four years ago while studying a level one Qigong course.Through regular practice, Qigong practitioners are said to be able to direct the energy in the body, the qi, towards the limbs."I completed it (the course) with a broken wrist and I could feel the energy repair much faster and the recovery time was better than they had actually thought," said the yoga instructor.Now totally hooked on Health Qigong and with 5,000 hours of practice to her credit, the 50-something Widmer explains it takes 10,000 hours of practice to achieve the title of "master.""While it looks like a physical process, it's actually very much more a spiritual process. Since we are electro-magnetic beings, it makes sense that we could send that current around in a positive way. But it does lead a person to longevity. It's a wellness that is authentic and I hope to be 100 years old and still doing it," she said."I have always enjoyed movement knowing that movement is health. And I would say that even people who aren't athletic can do this. It helps balance. Balance prevents falls, which prevents breakage. It is very beneficial to do this."

CANBERRA, Aug. 31 (Xinhua) -- Australia's new chief medical officer, Professor Chris Baggoley, on Wednesday said Australian should not be worried about reports that a mutant strain of the deadly bird flu virus is spreading across Asia and beyond.On Monday, the UN's Food and Agriculture Organization (FAO) said a mutant strain of the deadly avian influenza virus was spreading in Asia and issued a warning that the bird flu could spread from poultry to humans. It urged "heightened readiness and surveillance" as the mutant strain posed "unpredictable risks to human health."But Professor Baggoley, who took office on Tuesday, said Australia is well served by strict testing and customs regimes, adding that avian migration patterns also mean infected birds are highly unlikely to arrive in Australia."I don't think we should be worried," Prof Baggoley told Sky News."The country and the Australian government is certainly vigilant in relation to bird flu."Prof. Baggoley insisted the H5N1 virus remains overwhelmingly a disease of birds and it is very uncommon for humans to catch it. It is also exceedingly rare for humans to spread it among themselves.He said that even if bird flu did arrive and affected humans, Australia is ready to respond to any new and significant developments in bird flu."Australia tests migratory wild birds, looking for H5N1, and has been doing this for some years and has never found it," he said."On the human side of things, Australia has been preparing for a possible outbreak of H5N1 since 2004."We've got the laboratory capacity to diagnose influenza; we've got arrangements in place for a rapid production of an H5N1 vaccine for humans, and we've got ready access to antivirals."There have been no outbreaks of bird flu in Australia to date.The UN said the latest human death from bird flu occurred earlier this month in Cambodia, which has registered eight cases of human infection this year, all of them fatal.H5N1 has infected 565 people since it first appeared in 2003, killing 331.

BEIJING, Sept. 14 (Xinhuanet) -- Scientists had discovered the fossils of a new species of ancient carnivorous fish, National Geographic reported Monday.The newly-found ancient fish, "Laccognathus embryi", is a 1.8-meter-long predator, which was "waiting to lunge out to grab whatever was in front of it," said study co-author Ted Daeschler, a vertebrate zoologist at the Academy of Natural Sciences in Philadelphia, the U.S..It had a jaw filled with sharp teeth that were 1.5 inches long, the Journal of Vertebrate Paleontology described.The fish lived in the Devonian period, 415 to 360 million years ago, which "was a fish-eats-fish kind of world," Daeschler said. "There was a real arms race going. If you didn't have good armor on your body, you were very vulnerable.""It's not just finding the animal - it's also placing the animal in its evolutionary crucible," Daeschler added.Its closest living relative is the lungfish which can survive in the drought, scientists said.Scientists hope the finding can help in their study on the revolution of fishes as well as other species.
