WASHINGTON, Oct. 3 (Xinhua) -- Researchers at St. Michael's Hospital in Canada have discovered a new function for an enzyme that may protect against organ injury and death from anemia, according to a study appearing Monday in the U.S. journal of the Proceeding of the National Academy of Sciences.Researchers found that when people have anemia, neuronal nitric oxide synthase (nNOS) -- an enzyme in nerve cells that produces nitric oxide, an important signaling molecule in the body -- increases the body's ability to respond, adapt to low oxygen levels and makes the body more efficient in delivering oxygen to tissues. They also found that levels of nNOS in the brain increased in anemic mice, and that the mice without this enzyme die earlier, and with higher hemoglobin levels."Identifying this mechanism may lead to new therapies and approaches to improving outcomes for anemic patients," said Dr. Greg Hare, a researcher at the Li Ka Shing Knowledge Institute of the hospital and one of the lead investigators of the study.Anemia occurs when blood has a lower than normal number of red blood cells or hemoglobin -- an iron-rich protein that carries oxygen from the lungs and heart to the rest of the body. Cells need oxygen to survive and to produce energy for all bodily functions. The condition has many different causes including infection (malaria, HIV, parasites), nutritional deficiencies (iron, folate, B12), genetic mutations, pregnancy, trauma and surgical blood loss."This research will help us identify when an anemic patient is at greatest risk for injury and death when undergoing surgery," said Hare. "Research is underway to test these findings in humans."

SAN FRANCISCO, Jan. 12 (Xinhua) -- Microsoft on Thursday announced a patent licensing agreement with LG Electronics covering the South Korean manufacturer's tablets, smartphones and other consumer devices running Google's Android or Chrome operating system.In a press release, Microsoft said it marks the 11th deal with a device manufacturer leveraging Google's operating system platform, noting that "more than 70 percent of all Android smartphones in the U.S. are now receiving coverage under Microsoft 's patent portfolio."Terms of the deal were not disclosed. So far, Microsoft has struck major cross-licensing patent agreements with HTC, Samsung and Acer, among others.Last September, Microsoft announced a broad patent deal with Samsung. U.S. media reports cited South Korean media as saying that Microsoft had wanted Samsung to pay 10 to 15 U.S. dollars for each Android device.The booming mobile market has been harassed by acrimonious legal battles over patent infringement. Being an open source operating system, Google's Android has become a major target of patent suits.Microsoft has been going after companies that make phones and tablets running Android, rather than directly against Google. But the two tech giants are still engaged in public spats over the issue after Google's top legal officer posted a scathing blog last August accusing Microsoft and other companies of waging "a hostile, organized campaign against Android."Motorola Mobility, which Google announced to acquire in a 12.5 billion-dollar deal last August, currently is the last major Android device vendor that refuses to take a license from Microsoft.Frank Shaw, Microsoft's head of communications, used Twitter to taunt Google on Thursday, twitting "Hey Google -- we are the 70 percent" with a link to their press release.Brad Smith, Microsoft's executive vice president and general counsel, also tweeted "it's time to recognize that in patent world, lawsuits are the 1 percent; license agreements are the 99 percent. "Google so far has made no comments on the Microsoft-LG patent deal.

JERUSALEM, Jan. 12 (Xinhua) -- An Israeli company has developed a system that scans the brain and provides a three dimensional image of the nerve cell connectivity to treat brain diseases like Alzheimer's or HDHD.The firm ElMindA trademarked a non-invasive system, the BNA ( Brain Network Activation), that helps doctors visualize the connectivity between nerve cells and synchronization that can even measure the severity of the patients condition from one day to another, the Israel21c news site reported on ThursdayBy creating a three-dimensional image of the brain while asking the patients to repeat an activity several times, BNA developers hope this system will become a regular way of diagnosing brain illnesses."Our vision is that every psychiatrist and neurologist in the world will routinely send every patient for BNA tests," said Dr. Eli Zangvil, ElMindA's strategic advisor for business development. "Our test would add information and aid in diagnostics in a way no other existing technology can do," he added.BNA could help doctors find out exactly at what stage of the disease patients and prescribe the exact medication for them."To do that, we must collect a lot of data," Zangvil said. "To say this person has a certain disease or condition, I have to be able to compare their pattern to a normal brain pattern of a person of the same age and gender." he said.Researchers hope to gather the amount of data they need to obtain FDA approval in the U.S. by the end of 2012, and start marketing it to hospitals by 2013.

BEIJING, Dec. 18 (Xinhua) -- China's economic diplomacy will face growing challenges in the form of trade and exchange rate disputes, as well as the task of protecting overseas investment interests, over the next few years, experts said on Sunday.Next year will be an election year for the Unite States and France, and there is an increasing possibility for the two countries to use the "China threat" as an excuse for not dealing with their own economic issues, which will put Chinese diplomacy under pressure, said Ding Yifan, deputy director of the Institute of World Development of the Development Research Center of the State Council at a seminar on Chinese diplomacy.During the first half of 2012, several countries will remain in a grave debt crisis and may even see their crises deepen, Ding said, adding that this situation may create friction between China, the United States and Europe.Additionally, protecting China's growing overseas investments will pose new challenges for the country's diplomacy, Ding said.Chen Fengying, director of the Institute of World Economic Studies under the China Institutes of Contemporary International Relations, agreed that the protection of China's overseas investment interests will be an important task for Chinese diplomacy.During the past three decades, China has invested in more than 170 countries and regions, with outbound direct foreign investment topping 170 billion U.S. dollars.In the past 30 years, China has been focused on "bringing in" foreign investment; it may do more to facilitate its "going out" in the future, Chen said.Chinese economic diplomacy will serve the country's economic construction and the protection of its overseas interests, national interests and security, Chen said, adding that China's position in the world is closely related to its economic diplomacy.Chen said China has made several achievements in international economic governance, reflected by China's growing influence in the international arena and the posts held by Chinese officials in important international organizations.

SHANGHAI, Jan. 11 (Xinhua) -- China has allowed the Bank of East Asia (BEA) to issue yuan-denominated bonds in Hong Kong for a second time, about three years after it became the first foreign-invested bank to make a yuan bond issuance, the bank said Wednesday.BEA China Ltd, a wholly-owned subsidiary of the BEA, was given the approval by the National Development and Reform Commission of China to issue yuan bonds in Hong Kong, it said.Details on the amounts and timing of the offerings weren't available. In 2009, in a major landmark, the BEA issued its first yuan bonds in Hong Kong in an aggregate principal amount of 4 billion yuan (630 million U.S. dollars).The BEA was among the first foreign-invested banks to be given the green light to issue yuan-denominated bonds in Hong Kong, a move analysts say will bolster the international influence of the Chinese currency, also known as renminbi.Sun Minjie, deputy head of BEA China, said the second bond issuance will give the bank stable access to capital, improve its debt portfolio, and support its development on the Chinese mainland.
