BEIJING, Aug. 22 (Xinhuanet) -- U.S. presidential candidate Rick Perry's controversial stem-cell treatment may inspire desperate patients to follow his lead while causing medical and legal concerns, according to media reports Monday.The Texas governor underwent a procedure on July 1 where stem cells, made from fat taken from his body, were put into his bloodstream to see if they might find their way to fix a bad back.The treatment carries potential risks ranging from blood clots to infection to cancer and may even run afoul of federal rules, doctors say. File photo of U.S. Republican presidential candidate Texas Governor Rick Perry."As a highly influential person of power, Perry’s actions have the unfortunate potential to push desperate patients into the clinic of quacks,” Harvard’s stem cell expert George Daley told the Associated Press.Worries about the safety and wisdom of this treatment are widespread among stem cell researchers as such a treatment has not been thoroughly vetted by researchers or approved by the FDA.

BERLIN, June 9 (Xinhua) -- A 57-year-old man died of E. coli infection in Germany's Frankfurt Thursday, pushing the death toll from the bacteria to 30.The man had traveled with his wife to the city of Hamburg, an epicenter of the outbreak, Frankfurt authority said.Another two deaths were reported in the state of Lower Saxony, including a 68-year-old man and a 20-year-old woman, while more than 2,800 people in 14 countries have been infected since the deadly E. coli outbroke.German researchers detected again the deadly strain o104 of E. coli on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg in the state Saxony-Anhalt on Wednesday.German health minister Daniel Bahr expressed his cautious hope for the disease on Wednesday as the number of new infection is clearly going down.But he also admitted there will be new cases and more deaths have to be expected, as Germany's national disease control centre, the Robert Koch Institute reported more than 300 infection in Germany on the same day.The Robert Koch Institute also noticed the declining trend in new cases but it was not clear whether this was caused by people staying away from vegetables or the outbreak was truly waning.

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.

YUEYANG, Hunan, June 2 (Xinhua) -- The population of finless porpoises, an endangered species of freshwater dolphin that lives in China's Yangtze River, may decrease by over 80 percent over the next 30 years, experts said on Thursday after conducting a field survey along the river.The rare species will edge closer to extinction if no action is taken, said Wang Ding, a dolphin expert from the Hydrobiology Institute of the Chinese Academy of Sciences.Wang's team conducted a survey on Poyang Lake, Dongting Lake and other locations along the Yangtze from Sunday to Wednesday this week.The dolphin population currently stands at 1,000, even lower than that of the giant panda, Wang said.The dolphin population is decreasing by a rate of 6.4 percent annually, Wang said."The next ten years will be a critical period for the conservation of this species," Wang said.A long-lasting drought in central China has lowered water levels in many of the region's lakes and rivers, doing great harm to the dolphins' habitat and leading to a decrease in population, Wang said.Mei Zhigang, a member of Wang's survey team, said that human activity has also contributed to the dropping population.Mei said that large numbers of shipping vessels on the Yangtze have impeded the dolphins' migration path, causing them to reproduce less frequently.

BEIJING, Sept. 11 (Xinhua) -- Despite a series of disasters, Chinese people tend to believe that the moon is still round and bright in the Mid-autumn Festival.Falling on Monday, the 15th day of the eighth month in the Chinese calendar, it is an important Chinese holiday, next only to the Spring Festival, and a chance for family reunion under the full moon, a symbol for happiness and prosperity.A staff worker shows newly-cooked moon cakes during a Mid-autumn festival celebration activity held in Tianjin, north China, Sept. 11, 2011. Some 100 children from Tianjin and southeast China's Taiwan attended the activity on Sunday.FAMILY REUNIONIn the railway station of Nanjing, capital city of east China's Jiangsu Province, passengers lined in long queues while waiting for their trains on Saturday.Although the three-day holiday seemed too short for a long trip, Xiao Liang carried several bags with him. "I bought wine for my dad, boiled salted duck for my mom, and health products for my grand parents," the young man beamed.In the southwestern Guangxi Zhuang Autonomous Region, Li Yukun didn't believe that she could reunite with her son for holiday. In fact, she never thought she could see the three-year-old boy again.Two years ago, Xiao Wei (pseudonym) from the Dalun village of the Beiliu city was kidnapped. His parents were desperate. "On special occasions like the Mid-autumn Festival, we shed tears while missing him," Li said.Police finally managed to get clues that a similar boy was adopted in the neighboring Guangdong Province.Li prepared for a feast with policemen to celebrate reunion with Xiao Wei.Since a campaign was launched to rescue trafficked children in Guangxi in 2009, 339 children were saved, half of whom had been sent back and could reunite with their parents in this festival.In Sichuan, 10 prisoners with good records in jail were given an opportunity to go back home for the holiday."In the past I could only receive greetings from my relatives behind the bars," a woman surnamed Chen said. "This year, my dream for home finally came true."Meanwhile, 171 prisoners had their jail terms shortened so that they could be released before the Mid-autumn Festival.
