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.

WASHINGTON, Oct. 3 (Xinhua) -- The Rockefeller University confirmed Monday its Canadian-born cell biologist Ralph Steinman died three days before being awarded the Nobel Prize on Monday as the Nobel committee was unaware of his death at the time."Steinman passed away on September 30," the New York university said in a statement."He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design."The Nobel committee was unaware of Steinman's death when announcing this year's winners and it was unclear whether the prize would be rescinded because Nobel statutes don't allow posthumous award."The Rockefeller University is delighted that the Nobel Foundation has recognized Ralph Steinman for his seminal discoveries concerning the body's immune responses," says Rockefeller University President Marc Tessier-Lavigne."But the news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago after a long battle with cancer. Our thoughts are with Ralph's wife, children and family.""We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," says Steinman's daughter Alexis. "He devoted his life to his work and his family, and he would be truly honored.""Ralph's research has laid the foundation for numerous discoveries in the critically important field of immunology, and it has led to innovative new approaches in how we treat cancer, infectious diseases and disorders of the immune system," Tessier-Lavigne says.Steinman, who discovered the immune system's sentinel dendritic cells, is this year's recipient of the Nobel Prize in Physiology or Medicine. He shares half the prize with Bruce Beutler and Jules Hoffmann.

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."

SAN FRANCISCO, Nov. 29 (Xinhua) -- Hewlett-Packard (HP) on Tuesday issued a statement to refute some security flaw claims on its LaserJet printers."Today there has been sensational and inaccurate reporting regarding a potential security vulnerability with some HP LaserJet printers. No customer has reported unauthorized access. Speculation regarding potential for devices to catch fire due to a firmware change is false," HP said in the statement.Tech blog "The Red Tape Chronicle" reported earlier Tuesday that researchers from Columbia University found that a feature named "remote firmware update" on HP's Internet-connected LaserJet printers could allow hackers take control of the device by installing malicious software, and even manage the printer to catch fire.In the statement, HP said that its LaserJet printers have a hardware element called "thermal breaker" that is designed to prevent a part of the device from overheating or causing a fire, noting that it cannot be overcome by a firmware change as it was reported.The Palo Alto, California-based company said that the specific vulnerability exists for some HP LaserJet printers it placed on a public Internet without a firewall. It conceded that on Apple's Mac computers and PCs running Linux system, it is possible for a specially formatted corrupt print job to trigger a firmware upgrade.The company said that it is building a firmware upgrade to mitigate the issue and suggested consumers could place printers behind a firewall and disable remote firmware upload on exposed printers.Researchers said in the earlier report that they believed the flaw is not limited to HP printers and millions of printers around the world could be vulnerable to hack attacks.

BEIJING, Oct. 8 (Xinhua) -- Authorities hope to innovate social management by restructuring its governmental organ, an official said in an interview with Xinhua and the People's Daily on Saturday.The organ, the Central Committee for Comprehensive Social Management, was renamed and restructured in a meeting last month from the previous Central Committee for Comprehensive Management of Public Security.With 11 more departments than the previous one, the new committee, with 51 departments, is expected to strengthen and innovate social management so as to build a harmonious, stable society, an official from the general office of the committee said.The official said the renaming and restructuring of the committee came as the former's concepts, mechanisms and measures fell behind China's fast social and economic development after its 20 years of existence.The official said the new committee will primarily address some major issues that could threaten social harmony and stability, such as criminal gangs and juvenile delinquency, while enacting laws and regulations for social management.
