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.

BEIJING, Sept. 28 (Xinhua) -- Chinese banks have extended more loans to small firms to ease their financial predicaments as the government tightens monetary supply, a banking regulator said Wednesday.Outstanding loans to small firms grew 26.6 percent year-on-year to hit 9.85 trillion yuan (1.55 trillion U.S. dollars) at the end of July, said Xiao Yuanqi, an official in charge of financial services for small enterprises at the China Banking Regulatory Commission.The growth was 10 percentage points higher than that of the banks' total outstanding loans, Xiao told Xinhua.More than 100 commercial banks have set up special operations to ease small firms' difficulties getting access to bank credit, he noted.The figures came at a time when China is trying to balance the missions of countering inflation and sustaining the growth of small enterprises.The People's Bank of China, or the central bank, has raised the benchmark interest rate three times this year and increased the reserve requirement ratio six times.The measures bit into small, cash-strapped companies, which are already disadvantaged in seeking bank support due to insufficient collateral.Only 15 percent of China's small enterprises could get loans from banks and half of them had to resort to private lenders, according to a report by the National School of Development with Peking University in July.With tighter liquidity and stricter regulatory requirements on capital-adequacy ratios and loan-deposit ratios, banks are more reluctant to lend to small firms, said Ai Min, a retail banking general manager with China Minsheng Banking Corp., Ltd.Besides, the expanding size of lending to small firms may lead to higher risks, said Ai.He suggested banks improve the risk evaluation and collateral system for loans to small firms.

SAN FRANCISCO, Sept. 2 (Xinhua) -- A late-season potato blight has been detected on farms in Alaska, only the fourth time the disease appear in the U.S. state since 1995, local media reported on Friday.The disease was found this week in the fields of potato producers in cities of Delta Junction and Palmer, according to the Fairbanks Daily News-Miner, Alaska's second largest daily newspaper.Farmers in both fields are working to prevent the spread of the blight, a fungus-like disease that can kill plants in the field or cause potatoes to rot in storage, the newspaper reported.Growers have been asked to kill all affected plants within 100 feet, and plant samples from both sites will be examined to identify what type of late blight is involved.Experts said that blight can be controlled through the use of fungicides, but the cool, damp weather this summer in the areas has created an ideal environment for the disease to spread.Although Alaska's potato crop is tiny compared to other U.S. states, it has been viewed as a possible global source of seed potatoes in recent years because it is largely free of disease.A local university has explored partnerships with Chinese growers to export certified seed potatoes, noted the Fairbanks Daily News-Miner report.

MOSCOW, Aug. 3 (Xinhua) -- Two Russian cosmonauts manually launched a mini satellite from the International Space Station ( ISS) during a six-hour spacewalk Wednesday, said the Mission Control center near Moscow.Sergei Volkov and Alexander Samokutyayev, who started the spacewalk with a 20-minute delay, found the 30-kg Kedr has lost one of its two antennas during its delivery to the ISS in January. After consulting with the Mission Control, they have decided to launch the device anyway, Interfax news agency reported.The Kedr satellite, which was made by Russian students, was created to transmit from the orbit greetings in 15 languages about the 50th anniversary of Yuri Gagarin's first space flight. It could also photograph the Earth and re-transmit information from the ISS equipment.During the spacewalk, the cosmonauts were expected to install new stream video equipment on the station's outer surface, and to take pictures holding photos of the founders of Russian space explorations, including Konstantin Tsiolkovski, Sergei Korolyov and Yuri Gagarin.
