COPENHAGEN, Nov. 3 (Xinhua) -- The launch of Shenzhou-8 and the successful docking with Tiangong-1 in outer space represented a milestone in both Chinese and international space programs, Danish space scientist and media said Thursday.Michael Linden-Voernle, an astrophysicist at the Tycho Brahe Planetarium in Copenhagen, said new possibilities have opened for both Chinese and international space programs with high expectations."The recent launch of the Tiangong-1 module and now the successful docking with the Shenzhou-8 spacecraft is a very important step - a milestone for the Chinese space program in order to realize the goal of having a permanent presence in space. That means a large space station so this is really an important step, a major milestone," Linden-Voernle told Xinhua in an interview here on Thursday.Besides, a number of Danish news media reported the event, hailing it as a "historic and successful docking." The influential daily Politiken placed a two-minute's video for the successful coupling on its website and showed scenes from the Shenzhou-8 docking with Tiangong-1 together with a short commentary."Tonight two Chinese spacecraft made the historic and successful docking above the atmosphere for the first time ever. China had been the third country in the world after the United States and Russia to master the technique of docking in space. China has laid the foundation for its dominance in space," Politiken said.Jyllands-Posten, one of the bestselling newspapers in Denmark, carried a report with a brief description of China's first space docking under the headline "China closer to its own space station.""As the third country in the world, China has docked two spacecraft together perfectly in space," said Jyllands-Posten.China's unmanned spacecraft Shenzhou-8 and its space lab module Tiangong-1 rendezvoused early Thursday, successfully completing the country's first-ever space docking.

UNITED NATIONS, Nov. 21 (Xinhua) -- Dramatic progress in science, political leadership, and results indicate that 2011 was a "game changing" year for the international AIDS response, and much progress has been made in 2011 to check AIDS-related deaths since 1997, the peak of the epidemic, a new report released by the Joint United Nations Program on HIV/AIDS (UNAIDS) said on Monday."The Report on the Global AIDS Epidemic 2011" found that new infections were reduced by 21 percent since 1997, and deaths from AIDS-related illnesses decreased by 21 percent since 2005, according to the report.Furthermore, 47 percent (6.6 million) of the estimated 14.2 million people eligible for antiretroviral therapy treatment in low- and middle-income countries were accessing treatment, in increase of 1.35 million people since 2009.The report also found early signs that HIV treatment is having an impact on reducing the number of new HIV infections. As treatment reduces the viral load of a person living HIV to almost undetectable levels, it also reduces the risk of transmitting the virus to an uninfected partner, according to the report. Studies also show that treatment can be up to 96 percent effective in preventing HIV transmission among couples.Eleven countries, including many Sub-Saharan African countries, reached "close to universal access" for AIDS treatment, which is determined to be 80 percent access, in 2011.Botswana made the most dramatic progress in scaling up access to treatment, the report said. While sexual patterns remained relatively stable in the country since 2000, access to treatment increased from less than 5 percent in 2000 to more than 80 percent in 2011.Despite progress, however, the report does note that 2011 marks an unprecedented high the number of people infected with HIV worldwide.Globally, an estimated 34 million people are currently living with the infection. Approximately 2.7 million got infected with the virus in 2010, and as many as 1.8 million people died of AIDS- related illnesses in 2010.Yet the report also notes estimates that as many as 2.5 million deaths are estimated to have been averted in low- and middle- income countries due to increased access to HIV treatment since 1995."Now is not the time to reduce our efforts despite some good news on reducing new infections. Infections are decreasing, but not rapidly enough," said Kim Nichols, executive director of African Services Committee, on Monday at a press conference."There are fewer AIDS deaths, but with the number of infections increasing, prevention has to be the mainstay of our response," Nichols said.Indeed, the UNAIDS report calls for a new framework for investments which are focused on "high-impact, evidence-based, high-value strategies," according to a press release from the UNAIDS website.The framework, which aims to achieve universal access to treatment and prevention centers by 2015, requires a 22-24 billion US dollar funding increase by 2015.Given the withering state of the global economy -- donor funding for the AIDS response has dropped from 7.6 billion in 2009 to 6.9 billion in 2010 -- raising that kind of money may be a long shot. Regardless, UNAIDS'new investment plan calls for smarter uses of less money.According to the report, the framework will focus on high-risk populations like sex workers, men who have sex with men, and people who inject drugs and prevent infections among children, as well as invest in behavior change programs, condom promotion, and treatment, care and support for people living with HIV."The world faces a clear choice: maintain current efforts and make incremental progress, or invest smartly and achieve rapid success in the AIDS response," says the UNAIDS report.

BEIJING, Nov. 28 (Xinhuanet) -- A majority of the emergency hospitalizations for bad events related to medication use in old U.S. adults stem from four common medications, according to a new study in the New England Journal of Medicine Monday.The study was conducted by researchers from the Centers for Disease Control and Prevention of U.S.There are nearly 100,000 emergency hospitalizations for adverse drug events in older Americans, says researcher Daniel S. Budnitz, MD, MPH, director of the CDC's Medication Safety Program.And the four types of medication -- two for diabetes and two blood-thinning agents -- account for two-thirds of those drug-related emergency hospitalizations. They most often cited: warfarin (Coumadin, Jantoven); insulin; antiplatelet drugs such as aspirin and clopidogrel (Plavix); oral hypoglycemic agents."Both blood thinners and diabetes medicines are critical drugs that can be lifesaving," Budnitz says.However, he says that ''these are medications that you do need to pay attention to," being sure the dose and timing are correct, among other measures.

WASHINGTON, Nov. 11 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved HEMACORD, the first licensed hematopoietic progenitor cells-cord cell therapy.HEMACORD is indicated for use in hematopoietic stem cell transplantation procedures in patients with disorders affecting the blood forming system. For example, cord blood transplants have been used to treat patients with certain blood cancers and some inherited metabolic and immune system disorders."The use of cord blood hematopoietic progenitor cell therapy offers potentially life-saving treatment options for patients with these types of disorders," said Karen Midthun, director of FDA's Center for Biologics Evaluation and Research, in a statement.HEMACORD contains hematopoietic progenitor cells (HPCs) from human cord blood. Cord blood is one of three sources of HPCs used in transplants. The other two are bone marrow and peripheral blood. Once these HPCs are infused into patients, the cells migrate to the bone marrow where they divide and mature. When the mature cells move into the bloodstream they can partially or fully restore the number and function of many blood cells, including immune function.

BEIJING, Jan. 05 (Xinhuanet) -- Tighter licensing and banning unlicensed food processors are two measures needed to improve the poor quality of cooked food in Guangzhou markets, says a new proposal.The proposal, to be presented to the Guangzhou committee of the Chinese People's Political Consultative Conference, notes that producers of unpacked cooked food currently only need to obtain a food circulation permit.Many of them process food in unlicensed workshops with poor sanitation, and some producers even use substandard materials in food processing.The annual session of the conference opens on Tuesday.Recent tests of unpacked cooked food found that of 100 samples of meat, flour-based food, preserved vegetables, soybean products and algae products, only 38 passed the inspection.No cold dried bean curd or cold algae products passed the tests, which were carried out at seven supermarkets in Guangzhou, Guangdong province, by the city's consumers' commission.Excessive microorganisms were the main reason for failing the tests. Fifty-five samples contained excessive coliform and 12 had golden staph.Meanwhile, in tests of unpacked cooked food at supermarkets in Guangzhou by the city's commerce authority in the third quarter of last year, only 28 of the 71 samples passed the tests. In addition to excessive bacteria, excessive use of coloring agents was also spotted.The situation at other markets, such as wet markets, is more worrying, says the proposal.It also suggests that separate cooked food processing areas be built in local markets, with closer scrutiny over them.Standards concerning the processing, storage and transport of those food products remain unspecified.Some supermarkets, on the other hand, have been lax in selecting suppliers and failed to install protective facilities in shelving the food.Given that a number of government agencies are involved in food safety work, the proposal suggests that a shared information platform be built to prevent loopholes.The food associations should also play a bigger role in supervising food enterprises, it says."Since cooked food goes through the production, transport and shelving steps, it is hard to guarantee the quality. Even packed food has quality problems, not to mention unpacked food," said Ding Honghui, a resident who was shopping at a supermarket in Guangzhou."As far as I know, many government departments are involved in safeguarding food safety. They should strengthen the supervision and work more closely," he said.
