YICHANG, Oct. 30 (Xinhua) -- China's Three Gorges Dam on Sunday reached its designed highest mark, the second time for the world's largest water control and hydropower project to run at full capacity.The water level hit 175 meters at 5 p.m. after storing water for nearly two months from the water level of 152 meters, said an official with the China Three Gorges Project Corporation (CTGPC), the developer of the project.A dozen hydropower turbo-generator units started operation on Sunday, generating power capacity of 8.2 million kw, said the official.The dam in central China's Hubei Province completed its first full-capacity test last October.Operating at full capacity should give full play to the dam's functions of generating hydroelectric power, delivering water to the lower reaches to alleviate spring droughts, and containing water from summer flooding, as required by the State Flood Control and Drought Relief Headquarters.The Three Gorges Project was launched in 1993 with a budget equivalent to 22.5 billion U.S. dollars.So far, monitoring shows the dam is operating smoothly.

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."

TEL AVIV, Jan. 25 (Xinhua) -- Israeli Prime Minister Benjamin Netanyahu on Tuesday praised the relations between Israel and China at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between the two countries."We may be celebrating 20 years of relations, but our peoples are now celebrating a thousand years of friendship," Netanyahu said.He mentioned China's fair treatment towards the Jewish communities in the past, and the safe-haven given to them during the holocaust. "Like the Chinese people, the Jewish people have a long memory. We always remember our friends. We always remember people who extended a hand to us in our darkest days and we are grateful for China for that."Israli Prime Minister Benjamin Netanyahu (R) speaks at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between China and Israel in Tel Aviv on Jan. 24, 2012.The prime minister said that the friendship between the two sides can further deepen. "I think we barely scratched the surface of Israeli-Chinese relations. I have no doubt that in the coming years we'll see a dramatic expansion of these ties," he said."We've talked about doubling the trade (between the two countries). Well, I'd like to see a doubling of a doubling of the trade. I think Israel and China together are a winning combination, " Netanyahu said.In addition to the prime minister, several other senior Israeli officials attended the reception, among them ministers, former ambassadors and envoys to China and key figures in the bilateral ties.Chinese ambassador Gao Yanping said that "Over the past 20 years our pragmatic cooperation has been booming. When we started our diplomatic relations in 1992, our two-way trade volume was only a little bit more than 50 million U.S. dollars. Now the trade volume we have in two days equals that of the whole year of 1992."She said that "The further development of China-Israel relations is not only beneficial to both countries and the two peoples, but also very much conductive to regional stability, world peace and global prosperity.""Facing the ongoing major transformation and adjustment in the region and in the world, the China-Israel relationship is now at a new historical point. We should continue to work together, grow together and succeed together in the years to come," Gao added.

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.
