SYDNEY, Aug. 2 (Xinhua) -- Australia's general practitioners ( GPs) will not back the idea of routine prostate cancer tests for men as young as 40 despite growing calls for regular screening, the nation's largest professional general practice organization said on Tuesday.Spokesman for the Royal Australian College of General Practitioners (RACGP), Professor Chris Del Mar said there was not enough solid evidence to suggest major benefits from routine screening and that current tests were unable to detect "nasty" and potentially deadly forms of prostate cancer from ones that will not cause any harm."The problem is you end up treating lots of people who don't need to be treated," Del Mar said, adding that treatment could leave men impotent and with incontinence problems."You will treat 20 times as many people than would have ever been bothered by it. We don't yet know that treating prostate cancer is better than not treating it. We are not sure it does any good and could be doing more harm," he said.On the other hand, Australia's urologists and pathologists both want men aged 40 and over who are worried about developing the disease to be offered tests.The Royal College of Pathologists (RCPA) on Tuesday released an official recommendation on routine screening for men aged 40 and over if they were concerned about prostate cancer.The pathologists argue that blood tests for prostate cancer in men under 50 can predict their future risk of developing the disease by measuring their prostate specific antigen levels (PSA).They say that men with high PSA levels for their age should be tested annually, while those PSA levels are below the average could be tested less frequently.Their call for more routine testing contrasts with recommendations for GPs, whose `Red Book' medical guide does not support regular screening.Instead, it suggests GPs should inform men aged 50-70 of the risks and benefits of screening and only test if the patient requests one.RACGP spokesman Del Mar, who co-wrote the RACGP's recommendations, said while the Red Book was being revised "we are not going to liberalize it".Prostate cancer is one of the most common forms of cancer in Australia.About 20,000 cases of prostate cancer are diagnosed each year, with 3,300 men dying.Given the debate around prostate cancer tests, the Royal College of Pathologists wants to work with GPs, urologists and other medical organizations to develop a consensus on how and when to test for the disease, in a similar way to how experts approach breast cancer."It would be a good outcome for prostate cancer if we worked towards developing more of an umbrella document which reflected consensus among different stakeholder organizations. ," RCPA President Paul McKenzie said.

PARIS, Sept. 21 (Xinhua) -- European heavy-lift launcher Ariane 5 lifted off two communication satellites Wednesday from the Kourou launch centre in French Guiana, live broadcast of the launching process showed.The rocket, carrying the two communication satellites Arabsat 5C and SES-2, was launched at GMT 2138.This was the fifth heavy-lift mission of Ariane 5 in 2011. Arianespace had planned six Ariane 5 missions through 2011.The satellite Arabsat-5C was developed for the Arab Satellite Communications Organization (Arabsat) to provide satellite capacity in both C-band and Ka-band frequencies for a wide range of communications services.Jointly produced by Europe's EADS Astrium and Thales Alenia Space, it will be positioned at 20 degree East orbital location to cover the Middle East and Africa.Manufactured by Orbital Sciences Corporation of the United States, SES-2 will join the fleet of European satellite telecommunications operator SES, and is to be positioned at 87 degree West for coverage over North America and the Caribbean.Both Arabsat-5C and SES-2 have life-spans as long as 15 years.This Ariane 5 dual-passenger mission was postponed from Tuesday due to local strikes of French Guiana workers.Founded in 1980 as the world's first launch service and solutions company, Arianespace planned to achieve six Ariane 5 missions through 2011. Through 2010, heavy-lift workhorse Ariane 5 finished six missions, sending a dozen spacecraft into expected orbits.The next mission from Arianespace centre in Kourou was scheduled for Oct. 20 by medium-lift vehicle Soyuz. It will be Soyuz' first mission from French Guiana with a pair of satellites for Europe's Galileo satellite navigation system.

BEIJING, Sept. 8 (Xinhuanet) -- Middle-aged white women drinking alcohol moderately are more likely to stay healthy than nondrinkers, according to a new study from Harvard.The study has followed about 14,000 mostly white women since 1976.As a result, compared with teetotalers, those who had 3 to 15 alcoholic drinks weekly in their late 50s were 28 percent higher of being free from physical disability, chronic illness, mental health problems, and cognitive decline at the age of 70.Even having just one or two drinks per week increased a woman's odds of good health by 11 percent.However, women should be aware that even moderate drinking has been linked to an increased risk of breast cancer, said Qi Sun, M.D., a lead author of the study and a nutrition researcher at the Harvard School of Public Health.These findings don't necessarily apply to men or to nonwhite women. But they reinforced the evidence for the health benefits of moderate drinking.

BERLIN, June 8 (Xinhua) -- The deadly strain for the E. coli outbreak was found again on cucumbers, authorities of German state Saxony-Anhalt said on Wednesday. The strain O104 was found on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg, said State Health Minister Holger Paech.The dustbin belongs to a family in which three members have been ill. Paech said. The father only suffered a slight stomach upset, while the mother was once treated at a hospital and is now released. Their daughter is suffering from hemolytic-uremic syndrome (HUS), a serious complication from the infection of E. coli.However, experts were not clear about how the bacteria came to the cumbers, which have been in the dustbin for a week and a half."It is not clear and we are not able to determine how it reached there." Paech said.German authority first detected such bacteria from Spanish cucumbers on May 26, which has been overthrown by the laboratory tests in Hamburg last Tuesday.On Sunday, German State Lower Saxony issued a warning on bean sprouts as a possible source for the outbreak, which was proven to be negative on Monday.The German government has faced increasing criticism from abroad and at home for dealing with this crisis, as it has wrongly blamed the source of the infection for twice and there is a lack of coordination between different research institutes on the outbreak.John Dalli, European Union Health Commissioner, was quoted by local daily Die Welt saying "we have to rely on the experience and expertise across Europe, and even outside Europe."The Max Planck Institute for Infection Biology in Berlin also called for a federal government representative to coordinate the various government agencies which are dealing with the crisis.A federal government representative could increase cooperation between ministries and reduce mixed messages from the government, said director Stefan Kaufmann.On the same day, Germany's national disease control center, the Robert Koch Institute, said the number of infection has shown an overall decreasing trend but it is still uncertain whether the decline is due to people staying away from vegetables or to the waning of the source of infection.Until Wednesday, 25 deaths have been reported while the infection cases have increased more than 2,600 in 12 countries around the world.
