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."

BEIJING, Dec. 2 (Xinhua) -- China cannot use its 3.2 trillion U.S. dollars in foreign exchange reserves to rescue other countries, a senior diplomat said on Friday."The argument that China should rescue Europe does not stand, as reserves are not managed that way," Vice Foreign Minister Fu Ying said at the Lanting forum, a gathering of Chinese officials, scholars and social groups held by the Ministry of Foreign Affairs to discuss international issues and foreign policy."China is not absent from international efforts to rescue Europe; it has been a positive and healthy participant," Fu said.Since the outbreak of the European financial crisis, China has dispatched more than 30 procurement delegations to Europe, helping to boost imports from the continent, Fu said.Fu added that there are many misunderstandings about the use of China's foreign reserves. "Foreign reserves are not domestic income or money that can be disposed of by the premier or finance minister," she said."Foreign reserves are akin to savings, and their liquidity should be ensured," Fu said."Foreign reserves are not revenue and cannot be relocated randomly. Under this circumstance, China should take the prospect of yields into consideration if it invests its foreign reserves," said Tian Dewen, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.However, the outlook for the economic situation in the eurozone is currently uncertain, Tian said.Fu said China learned a lesson about the importance of foreign reserves during the Asian financial crisis of the late 1990s. ' "Reserves cannot be used domestically to alleviate poverty or taken abroad for development support," she said.She said that the way in which foreign reserves are managed should be in line with the principles of "safety, liquidity and proper profitability.""China's purchases of European bonds, International Monetary Fund bonds and U.S. bonds are also based on those principles," Fu said.Fu also said that China has no intention to gain profit by leveraging financial instruments."China will make efforts to overcome the crisis with Europe and the international community in the future," Fu said."As for the current turbulence in European markets, an authoritative voice is necessary in restoring market confidence. However, voices are diversified in Europe due to its political framework," said Chen Xin, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.Fu also reviewed achievements made in trade and investment cooperation between the two sides."It is normal for Europe to strengthen its economic cooperation with China in the process of conquering its difficulties, although it is not proper to add negative political implications," Fu said.She urged Europe not to politicize China's foreign investments."Successful investment should be reciprocal. We hope our economic activities are not interpreted from a political prospective and are not imbued with political interests. We should follow market economy principles," Fu saidFu also took time to single out media reports about the crisis that she believes have been overtly political."Many European countries have shown their understanding and support for us, but there have also been some negative reports," Fu said."We should treat each other with a moderate and impartial mentality. That will make bilateral relations easier to handle," Fu said.She cited an investment bid by a Chinese company in Iceland that was turned down by the country's government.Zhongkun, a private Chinese real estate company founded in 1995, planned to buy 300 square km of land in Iceland to build a high-end resort with a total investment of 200 million U.S. dollars.However, Iceland's Interior Ministry rejected the bid, citing the size of the area of land involved and the fact that there is no precedent in Iceland for foreign countries to purchase large tracts of land.

BEIJING, Nov. 30 (Xinhua) -- China's efforts to fight AIDS are impressive and its experience can be shared, according to Michel Sidibe, executive director of the Joint United Nations Programme on HIV/AIDS (UNAIDS)."We have seen progress in terms of new infections. The number of people going into treatment is increasing and the mortality rate is going down very quickly in China," Sidibe said during an interview with Xinhua on Wednesday.Sidibe said he was impressed by the country's political leadership and commitment to controlling AIDS.According to UNAIDS, the country has reported a 60-percent reduction in deaths due to AIDS over the past eight years.New HIV infection cases in China have been reduced from 70,000 people annually in 2005 to around 48,000 in 2011, according to the country's health department."However, China's success will not only be measured by what it has done for the Chinese people," Sidibe said.China has successful experience in reducing new HIV infections among intravenous drug users, which can be shared with the rest of the world, particularly east Europe and south Asia where HIV infections among drug abusers is a major challenge, he said.Sidibe suggested that the country should work with the rest of the developing world, particularly Africa, in fighting AIDS.A partnership between China and Africa will make a "big, big difference" in reducing AIDS mortality rates and introducing new technology and perspectives in Africa, said the official who had worked for UN in several African countries for more than two decades.Admitting the challenges of funding AIDS control programs during the current global economic downturn, Sidibe called for global solidarity and increasing shared responsibilities among countries."It is a critical moment now. It is not a time to stop investment but to redouble our efforts, to make sure that we will continue to make progress in the fight against HIV," Sidibe said."Getting to Zero" has been chosen as the main theme of World AIDS Day for the next five years, referring to UNAIDS' vision of "zero new HIV infections, zero discrimination and zero AIDS-related deaths."Sidibe met with Li Congjun, president of the Xinhua News Agency, on Wednesday before the interview. The agency has launched a global media campaign in cooperation with UNAIDS to raise public awareness about HIV/AIDS."The partnership (with Xinhua) is not only about writing news about HIV. It is about helping people to change their attitude and make decisions to help protect themselves," Sidibe said.

BEIJING, Oct. 10 (Xinhua) -- The State Council, or China's cabinet, announced on Monday it will tax all resource products starting Nov. 1, extending the resource tax on domestic sales of crude oil and natural gas from some regions to the entire country.The list of taxable resources widened from crude oil and natural gas to coal, rare earth, salt and metal from Nov. 1, according to the country's revised resource tax regulations.The expansion of the resource tax is part of China's efforts to encourage energy conservancy and limit environmental damage.Sales of crude oil and natural gas nationwide will be taxed at a rate between five and 10 percent of their sales value, according to the revised regulations.The regulations impose a sales tax ranging from eight (1.25 U.S. dollars) to 20 yuan per metric ton on coking coal and from 0.40 to 60 yuan per metric ton on rare earth ore.Taxes on other types of coal stood unchanged at 0.30 to five yuan per metric ton.The tax rate for other non-ferrous metals is set between 0.4 to 30 yuan per metric ton. Ferrous metals will be taxed at two to 30 yuan per metric ton.Taxes on precious non-metallic ore will be between 0.5 to 20 yuan per kg or per carat, while taxes on cheap non-metallic ore are set between 0.5to 20 yuan per metric or per cubic meter.China's current resource tax is levied based on production volume instead of sales value, thus preventing the government from benefiting from energy and commodity price increases.Nonetheless, energy giants and mining companies such as PetroChina and Sinopec have enjoyed large profit margins on the sale of resources under the current tax scheme.A resource tax on oil and natural gas was introduced at a rate of five percent in northwest China's Xinjiang Uygur Autonomous Region on June 1, 2010 before being extended to 11 other provinces in December last year.
