CANBERRA, June 6 (Xinhua) -- Australian beef is not to blame for a recent outbreak of E.coli in Japan, Meat and Livestock Australia confirmed on Monday.Twenty people have fallen ill in Japan's Toyama prefecture, with 15 of them infected with the O157 strain of E.coli after eating at a popular Korean-style barbecue restaurant chain, Gyukaka, on May 6.The operators of the restaurant chain, REINS International, said they suspected the bacterium might have been carried by beef imported from Australia.After conducting an investigation into the Japanese outbreak, regional manager for Meat and Livestock Australia, Melanie Brock, said testing shows Australian beef was not the source of the outbreak."The Toyama prefecture health authorities have confirmed following a thorough inspection that imported Australian beef was not the source of an incident of E.coli," Brock said in a statement on Monday."The authorities continue to investigate other food consumed by the affected customers."Brock said Australian beef has long been recognized by the Japanese trade and consumers for its strong safety record.Brock added that Australian beef for export to Japan is processed under the veterinary supervision of the Australian Quarantine and Inspection Service, and is recognized internationally as bearing a high hygienic standard.

STOCKHOLM, July 7 (Xinhua) -- A patient has been given a new trachea made from a synthetic scaffold seeded with his own stem cells in a Stockholm's hospital, the Swedish medical university Karolinska Institutet said on Thursday.The operation was performed on June 9th at Karolinska University Hospital in Huddinge and the patient, a 36-year old man, has been well on the way to recovery and would be discharged from the hospital on Friday, the university said in a statement.The patient had been suffering from late stage tracheal cancer with the tumor had reached approximately 6cm in length and was extending to the main bronchus.Since no suitable donor windpipe was available, the transplantation of the synthetic tissue engineered trachea was performed as the last possible option for the patient.The successful transplantation of tissue engineered synthetic organs, referred to as regenerative medicine, could open promising therapeutic possibilities for the thousands of patients who suffer from similar conditions.Transplantations of tissue engineered windpipes with synthetic scaffolds in combination with the patient's own stem cells as a standard procedure means that patients would not have to wait for a suitable donor organ.This would be a substantial benefit for patients since they could benefit from earlier surgery and have a greater chance of cure, according to the statement.

BEIJING, August 1 (Xinhuanet) -- U.S. researchers have discovered a genetic mutation unique to African Americans that links to heighten their asthma risk, according to reports published on Sunday in the journal Nature Genetics.Researchers of University of Chicago found a gene, PYHIN1, and its variations may account for asthma risk in people of African descent. In their study, they examined data from nine previous genome-wide association studies, totaling more than 2 million single nucleotide polymorphisms in 3,246 asthma patients and 3,385 control patient, 1,702 patient-parent groupings, 355 family-based cases, and 468 family-based controls.In the study, the researchers found that between 26 percent and 29 percent of people of African-descent carried at least one copy of the gene.  In particular, one polymorphism of the gene was 34 percent more likely found in African-American and Afro-Caribbean people with asthma.  More interestingly, this variant of the gene is rarely found in Caucasian people and in Latino population, it was found in less than 5 percent.This new variant is part of a family of genes linked with the body's response to viral infections. It is thought to be involved in interferon signaling, which could influence the occurrence of asthma.The team stressed that each gene variant on its own plays only a small role in increasing asthma risk, but that risk could be multiplied when combined with other risk genes and with environmental factors.

CANBERRA, Aug. 29 (Xinhua) -- An Australia report released on Monday draws a direct link between inaction on climate change and long-term social and mental health problems.The Climate Institute report, A Climate of Suffering: The Real Cost of Living with Inaction on Climate Change, points that in the wake of extreme weather in Australia, such as cyclones and droughts, there is an increase in depression, anxiety, post- traumatic stress and substance abuse.As many as one in five people reported "emotional injury, stress and despair" in the wake of these events.The report also warns continuing catastrophic weather events are creating anxiety and insecurity for children at levels not seen since the Cold War.It claims one in 10 children of primary school age showed symptoms of post-traumatic stress disorder after Cyclone Larry in 2006.According to Professor Ian Hickie, from the Brain & Mind Institute, regional and remote communities are most vulnerable to the impact of climate change.He said a recent study of rural New South Wales where, following the long drought, self-harm and suicide rose by up to eight percent."I think what we are seeing now is a much more significant counting of not just the short-term costs and reactions but the longer-term costs, the loss of community cohesion and that being essential to people's long-term mental health," Professor Hickie."The drought was a particularly instructive event for everyone in Australia and we saw a lot of focus for the first time on the mental health effects, particularly suicides in rural families, the effect on rural communities of prolonged examples of weather change," Hickie said.Climate Institute chief executive John Connor said that not only did natural disasters cost taxpayers about nine billion U.S. dollars last year, but there are also damaging Australia's social fabric.He said that with Australian regions increasingly exposed to extreme weather, recognizing and managing the risks of climate change is essential, and it is an insurance policy to protect Australia's communities.The study came as the political and social debate over Australian federal government's proposed carbon tax intensifies.In 2007, a report by the Commonwealth Scientific and Industrial Research Organization (CSIRO) projected the effects of various greenhouse gas emission scenarios for 2030, 2050 and 2070.It said droughts were likely to become more frequent, fire danger was set to increase and tropical cyclones were likely to become more intense.
