DAVOS, Switzerland, Jan. 27 (Xinhua) -- A policy of more trade and greater openness to the rest of the world has brought significant benefits to China and greater market opportunities to its trading partners, the head of the World Trade Organization says."I don't think there is any question that China joining the WTO has been a very good thing for China and for the WTO and its members," WTO Director General Pascal Lamy said in an interview with Xinhua.The WTO chief was expected to join the forum "China's Impact on Global Trade and Growth" on the sidelines of the World Economic Forum annual meeting held in this Swiss alpine town."In joining the WTO, China successfully underpinned a policy of what had been 20 years of progressive openness," Lamy said.Adherence to economic reforms through international commitments ensured that China would stay on the path of openness, he noted, adding that the policy has helped the country economically, politically and socially.Lamy stressed that China has done a "remarkable job" in reducing poverty, which is an important task for the country, along with registering double-digit growth, thus becoming the world's largest manufacturer and the second largest economy.Apart from enhanced market access with its trading partners and more equal treatment in global trade, WTO membership also has allowed China to gain access to the organization's dispute settlement system, Lamy said.According to a WTO report issued in December, as the world's biggest exporter, China ranks first in receiving anti-dumping (AD) investigations, with 23 new AD initiations directed at its exports in the first half of 2010.In recent rulings arbitrated by the WTO Dispute Settlement Body (DSB), China has won a poultry dispute against the United States, and a steel fastener case against the European Union.Being a WTO member, "China would have a seat at the table as negotiations commenced on the trade rules for the 21st century," Lamy said, referring to the decade-long Doha round of global trade negotiations aimed at building the next generation trading system.Even more importantly, for China, participation in the global system of rules and discipline greatly boosted investors' confidence and helped facilitate foreign direct investment in China, he said.On the other side of the coin, China's integration into the world trading system has given enormous driving force to the global economy and market opportunity to its trade partners.

WASHINGTON, May 11 (Xinhua) -- Johns Hopkins University researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.The work, published Wednesday in the journal Science Translational Medicine, suggests that liver cells derived from so- called "induced-pluripotent stem cells (iPSCs)" could one day be used as an alternative to liver transplant in patients with serious liver diseases, bypassing long waiting lists for organs and concerns about immune system rejection of donated tissue."Our findings provide a foundation for producing functional liver cells for patients who suffer liver diseases and are in need of transplantation," says Yoon-Young Jang, assistant professor of oncology at the Johns Hopkins Kimmel Cancer Center. "iPSC-derived liver cells not only can be generated in large amounts, but also can be tailored to each patient, preventing immune-rejection problems associated with liver transplants from unmatched donors or embryonic stem cells." A microsopic view shows human embryonic stem cells in various stages of differentiation into liver cells in this photo taken at Stanford University and released by the California Institute for Regenerative Medicine, March 9, 2009iPSCs are made from adult cells that have been genetically reprogrammed to revert to an embryonic stem cell-like state, with the ability to transform into different cell types. Human iPSCs can be generated from various tissues, including skin, blood and liver cells.Although the liver can regenerate in the body, end-stage liver failure caused by diseases like cirrhosis and cancers eventually destroy the liver's regenerative ability, Jang says. Currently, the only option for those patients is to receive a liver organ or liver cell transplant, a supply problem given the severe shortage of donor liver tissue for transplantation. In addition, mature liver cells and adult liver stem cells are difficult to isolate or grow in the laboratory, she says. By contrast, iPSCs can be made from a tiny amount of many kinds of tissue; and the embryonic stem- like iPSCs can grow in laboratory cultures indefinitely.For the study, Jang and colleagues generated human iPSCs from a variety of adult human cells, including liver cells, fibroblasts ( connective tissue cells), bone marrow stem cells and skin cells. They found that though the iPSCs overall were molecularly similar to each other and to embryonic stem cells, they retained a distinct molecular "signature" inherited from the cell of origin.

PARIS, May 20 (Xinhua) -- Heavy-load launcher Ariane 5, carrying two communication satellites GSAT-8 and ST-2, lifted off at around 22:38 p.m. Paris time (GMT 2038) on Friday from Europe' s Spaceport in French Guiana.Built by Japan's Mitsubishi Electric Company, ST-2 will offer Ku-and C-band relay services across the Middle East, Central Asia, India and Southeast Asia to the ST-2 Satellite Ventures joint company of Singapore Telecommunications Ltd (SingTel) and Taiwan' s Chunghwa Telecom Company Ltd..With a weight around 5.1 tons at launch, ST-2 was separated first around 27 minutes after the lift-off. It has a designed life of 15 years and will function at 88 degree East.The lighter passenger GSAT-8, built by the Indian Space Research Organization (ISRO), will serve to augment India's Ku- band relay capabilities and offer aircraft navigation assistance over Indian airspace and adjoining areas with its two-channel GAGAN system.GSAT-8 was expected to be ejected off around 31 minutes into the flight and will be orbited at 55 degree East. Weighed about 3. 1 tons, it has a designed life span of at least 12 years.Arianespace started its 2011 busy year for heavy-lift Ariane 5 with the milestone launch of Europe's second Automated Transfer Vehicle (ATV) on February 16.The next launch of Ariane 5 planned to lift off two TV broadcast and telecommunications relay satellites: BSAT-3c/JCSAT- 110R for Japan's Broadcasting Satellite System Corporation (B-SAT) and SKY Perfect JSAT Corporation, and ASTRA 1N for Luxemburg-based SES company.

BEIJING，March 11 (Xinhuanet) --A poor diet during pregnancy may result in health problems such as diabetes for the offspring in later life, according media reports Friday quotting a new research.Based on a study of rats, researchers from the University of Cambridge altered the protein content of the mother's diet during pregnancy as they found that rats were more vulnerable to the effects of diseases if their mothers were malnourished while they were pregnant.Further, the study also showed that an imbalanced diet in the expectant mother can compromise the long-term functioning of a gene in the child. And the gene, named Hnf4a, is believed to play a major role in the development of the pancreas and in the production of insulin.The researchers held similar mechanisms seen in the rat study could occur in humans, and that the effects might be felt by more than just the immediate offspring."What is most exciting about these findings is that we are now starting to really understand how nutrition during the first nine months of life spent in the womb shape our long term health by influencing how the cells in our body age," said Susan Ozanne, senior author of the paper and senior fellow from the Institute of Metabolic Science at the University of Cambridge.And Jeremy Pearson, associate medical director at the British Heart Foundation, said: "The reasons why are not well understood, but this study in rats adds to the evidence that a mother's diet may sometimes alter the control of certain genes in her unborn child.""It's no reason for expectant mothers to be unduly worried. This research doesn't change our advice that pregnant women should try to eat a healthy, balanced diet," he added.

SAN FRANCISCO, April 25 (Xinhua) -- Oracle Corp. on Monday announced that its co-president Safra Catz is taking the additional position as the software giant's chief financial officer (CFO), following the resignation of its current CFO Jeff Epstein.Epstein was named Oracle's CFO in September 2008, and had reported directly to Catz.
