WASHINGTON, June 20 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Monday unveiled in a report a new strategy to meet the challenges posed by rapidly rising imports of FDA- regulated products and a complex global supply chain.The report, titled "Pathway to Global Product Safety and Quality," calls on the agency to transform the way it conducts business and to act globally in order to promote and protect the health of U.S. consumers.According to the report, the FDA will partner with its counterparts worldwide to create global coalitions of regulators focused on ensuring and improving global product safety and quality. The coalitions of regulators will develop international data information systems and networks, and increase the regular and proactive sharing of data and regulatory resources across world markets.The FDA will build in additional information gathering and analysis capabilities with an increased focus on risk analytics and information technology. It increasingly will leverage the efforts of public and private third parties and industry and allocate FDA resources based on risk."FDA regulated imports have quadrupled since 2000. The FDA and our global regulatory partners recognize this new reality and realize we must work proactively and collaboratively to address the challenges we face," FDA Commissioner Margaret Hamburg said in a statement. "The FDA must further collaborate and leverage in order to close the gap between our import levels and our regulatory resources. This report is an important step in ensuring we are able to fulfill our critical public health mission."

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.

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.

BEIJING, July 5 (Xinhuanet) -- A black iPhone 4 prototype has appeared for sale on eBay and the highest bidding hit one million U.S. dollars as of Monday, according to media reports.The listing is set to expire on July 11.The seller "jtmaxo" said, "I am a licensed cell phone repairman, this iPhone was bought from a person who really didn't know who he had."The seller later was frustrated to find that it was unable to be activated via iTunes.According to a check through Apple’s database, it is indeed listed as a prototype, and it has the tester code "DF1692" etched in the bottom right corner.Different from the iPhone 4 sold on markets, the handset lacks the + and - on the volume buttons, although the screen is fully functional.The price for the prototype will not remain as high as it is as the seller said that several "non-legitimate" bids have already been deleted.
