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."

WASHINGTON, Dec. 1 (Xinhua) -- U.S. President Barack Obama announced Thursday that his administration is committing an addition 50 million U.S. dollars in funding for domestic HIV/AIDS treatment and care.Obama also set a new target of helping six million people in countries hardest hit by the HIV virus get access to life-saving antiretroviral drugs by the end of 2013, increasing the original U. S. goal by two million."We can beat this disease,"' Obama declared at a World AIDS Day event in Washington. Former Presidents George W. Bush and Bill Clinton also participated via satellite.Citing the success of the President's Emergency Plan for AIDS Relief program in providing antiretroviral treatment to people living with HIV/AIDS around the world, Obama admitted that new infections are still not going down in the United States."The rate of new infections may be going down elsewhere, but it 's not going down here in America,'' he said. "There are communities in this country being devastated still by this disease. When new infections among young, black, gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.''Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also told Xinhua recently that in the United States, the AIDS epidemic has plateaued, but it is still at "unacceptably high" level.About 1.2 million Americans are living with HIV and only 28 percent of them have the infection under control, the U.S. Centers for Disease Control and Prevention reported this week."The fight is not over," Obama declared, but "the federal government can't do this alone." He called on state governments, pharmaceutical companies, and private foundations, to do their part to help Americans get access to all the life-saving treatments.Obama also appealed to global partners to step up their efforts to end AIDS, some 30 years after the epidemic first surfaced. "So on this World AIDS Day, here's my message to everyone out there. To the global community -- join us," he said.

ADDIS ABABA, Oct. 22 (Xinhua) -- China on Saturday delivered portion of the first batch of emergency food assistance to Ethiopia.Wei Hongtian, Charge d'Affairs at the Chinese Embassy in Ethiopia, handed over the assistance certificate to Wondirad Mandefro, Ethiopian State Minster of Agriculture, in a ceremony held at the Office of the Ethiopian Disaster Risk Management Food Security Sector (DRMFSS) in Addis Ababa, Ethiopia.The handover was witnessed by Ahmed Shide, Ethiopian State Minister of Finance and Economic Development, and Qian Zhaogang, Economic Counselor at the Chinese Embassy in Ethiopia as well as officials and diplomats from the two countries.The charge d'affairs said the Chinese government has decided to provide Ethiopia with two batches of gratis emergency food aid valued at some 24 million U.S. dollars, as part of humanitarian assistance to the people affected by drought in the Horn of Africa region, about which the international community is concerned much.Months ago, China pledged to provide humanitarian aid to drought affected people in Ethiopia, Kenya and Djibouti.The 2011 drought in the Horn of Africa region has affected livelihoods of over 12 million people in countries of the region including Ethiopia.In this move, China has delivered large quantities of wheat to Ethiopia, and it is put in the central warehouse in Adama town, 90 km away from Addis Ababa, as the first batch of the 8,139.4 tons of wheat and 715.15 tons of rice donated by the government of China, said Ethiopian State Minister of Agriculture.According to the minister, the Chinese government has pledged around 20,000 tons of emergency food valued at 24 million dollars.Wei said China attaches great importance to the agriculture development and the food security in Africa. He said China has engaged itself in various agricultural cooperations with African countries including Ethiopia, in different channels."In the future, besides food assistance, China's agricultural cooperation with Africa will focus on technology demonstration, personnel training, infrastructure construction, promotion of agricultural production and trade, and experience sharing agriculture development," said the Charge d'Affairs.The rest portion and the other batch of the emergency food assistance pledged by China is expected to come in November and December.Wei assured that the rest batches of emergency food aid would come to Ethiopia on schedule. The Ethiopian state minister said the Chinese government is one of those donors that demonstrated its strong friendship with the Ethiopian government and its people by extending appreciable humanitarian support at critical time."The recent donation of 100, 000 U. S. dollars by a Chinese private company, Huajin Group Ltd, for food aid is a manifestation that even private companies join us in our efforts to containing problems associated with such natural disasters," said Wondirad."Despite a steady economic growth achieved these past eight years in Ethiopia that reached an average of 11 percent annually and our continued efforts to maintain and accelerate the momentum through the GTP, we are confronted by climate change induced disasters, of which drought remains the major one," said the minister."While reducing disaster risk and vulnerabilities through development interventions, the government of Ethiopia in collaboration with its partners is taking all the necessary measures towards further enhancing its early warning and response system with the view to reducing potential impacts of disasters, including that of drought enhanced preparedness and provision of timely and appropriate responses."The government of the People's Republic of China has been one of our major development partners supporting us in all these efforts," he added.The state minister commended the Chinese government and its people for standing with Ethiopia shoulder to shoulder at the critical time by donating appreciable size of emergency food aid.

BEIJING, Jan. 05 (Xinhuanet) -- China's satellite television channels have aired fewer entertainment programs this year as broadcasting watchdog's curbs on "excessive entertainment" took effect.The State Administration of Radio, Film and Television has cut two-thirds of "racy" entertainment programs on China's 34 satellite channels since the campaign began, the spokesperson for the administration said on Tuesday.Since the regulation took effect on Jan 1, the total number of entertainment programs scheduled for prime-time -7:30 pm to 10 pm - broadcast a week dropped to 38 from 126 at the end of last year, according to a statement from the administration.Under the regulation, announced in October, each satellite channel can broadcast no more than two entertainment programs a week and the maximum length of the program may not exceed 90 minutes.The targeted programs, including dating shows, reality talent shows and emotional stories on the administration's list, were deemed "excessive entertainment" and showing "less taste"."Satellite channels should design programs with innovative content, promoting traditional virtues and socialist core values in their new entertainment programs," the authority said.The administration considers the move crucial to improving cultural content for the public by offering high-level programs.Meanwhile, the number of news programs on the satellite channels has grown to 193 a day, 33 percent more than in 2011.Currently, news programming on each satellite channel has surpassed two hours, and each channel has at least two 30-minute news programs during prime time.But popular dating shows such as If You Are the One, produced by Jiangsu Satellite TV, and reality shows such as China's Got Talent, aired by Shanghai-based Dragon TV, will remain on during prime time in the weekend.Li Hao, spokesman for Hunan Satellite TV, a broadcaster famous for its entertainment programs, told China Daily the regulation will improve the quality of entertainment programs."We have been exploring how to make entertainment shows more meaningful and valuable," he said, adding that the channel has shortened the length of its two entertainment programs from 110 to 90 minutes."We will supervise programs more strictly, and pay close attention to things such as the clothing and comments of hosts and guests," he added.Cheng Manli, a media professor at Peking University, welcomed the new regulation to limit "less tasteful" programs involving violence and money worship."After all, unhealthy programs may hurt young people who are not able to distinguish right from wrong, which also worries their parents," she said.However, Yu Guoming, a professor at the School of Journalism at Renmin University of China, did not think the regulation was the way to improve cultural development."Whether the entertainment program is good or not should be decided by viewers' reaction, instead of an administration's evaluation," he said. "Residents are under pressure and need to watch shows to relax in our society."Yu also said that a good entertainment program should respect residents' taste and give them more viewing choices, or else it could lead to rigid restrictions.Ma Yuqiang, who runs an online clothing retail company, said the new rule will not affect his daily life, because he can watch the entertainment programs that were taken off prime time on the Internet."I think the regulation will drive most young people to the Internet," Ma, 26, said.
