SINGAPORE, July 6 (Xinhua) -- A team of researchers in Singapore has designed a tube with special robotic hands that allows doctors to perform surgery on a patient's inner organs without resulting in scars, local media reported on Wednesday.The special "robotic hands" were fixed to the tube to access a patient's stomach. Compared with traditional methods which use only one robotic hand, the new device known as master and slave transluminal endoscopic robot, or MASTER, is more nimble, thereby allowing complex operations, the Lianhe Zaobao reported.Louis Phee, an associate professor at the Nanyang Technological University who led the team of researchers, had spent six years to develop the gadget, which cut an eight-hour procedure to just 17 minutes, said doctors at India's Asian Institute of Gastroenterology.The gadget, still in the trial stage, has been tested earlier this month on three patients at the Indian hospital. It is also expected to be tried out in Germany and China's Hong Kong later. The patients can leave the hospital much sooner than they would have using traditional gadgets.Phee said he expected the gadget to be available on the market as early as three years from now, after going through clinical trials and getting the approval from authorities.He also saw a potential for the gadget to be used on other organs by cutting a small spit on stomach that allows the gadget to go through to access the site.

BEIJING, Aug 4 (Xinhuanet) – A new urine test might help doctors detect prostate cancer and better evaluate a patient's treatment options, according to American reseachers Thursday."This is a tool that men and their physician can use to help them decide whether it's appropriate to get a biopsy now or delay that decision," said lead researcher Dr. Scott Tomlins, a pathology resident at the University of Michigan Health System.The test looks for two genetic markers associated with prostate cancer. The first, called TMPRSS2:ERG, is caused by two genes changing places and fusing together; it is thought to cause prostate cancer. Since the gene fusion is only seen in about half of cancer patients, the test also looks for another marker, called PCA3."We are exploiting some new bio-markers to try to refine the PSA (prostate-specific antigen) test," Tomlins said.

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.

New York, Sept. 23 (Xinhua) -- A Chinese scientist was presented a prestigious U.S. award on Friday for the discovery of artemisinin, a drug therapy for malaria that has saved millions of lives across the globe, especially in the developing world. Pharmacologist Tu Youyou, 81, became the first scientist on the Chinese mainland to win Lasker Award, known as "America's Nobels" for their knack of gaining future recognition by the Nobel committee.Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, pioneered a new approach to malaria treatment that has benefited hundreds of millions of people and promises to benefit many times more. By applying modern techniques and rigor to a heritage provided by 5000 years of Chinese traditional practitioners, she has delivered its riches into the 21st century."Not often in the history of clinical medicine can we celebrate a discovery that has eased the pain and distress of hundreds of millions of people and saved the lives of countless numbers of people, particularly children, in over 100 countries," Lucy Shapiro, a member of the award jury and professor of Stanford University, said while describing Tu' s discovery.Shapiro said the discovery, chemical identification, and validation of artemisinin, a highly effective anti-malarial drug, is largely due to the "scientific insight, vision and dogged determination" of Professor Tu and her team. She thought Professor Tu's work has provided the world with arguably the most important pharmaceutical intervention in the last half century."The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said while receiving the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world."
