RIO DE JANEIRO, Oct. 21 (Xinhua) -- Representatives from 120 countries attending the WHO's World Conference on Social Determinants of Health on Friday pledged to maintain investments in healthcare to reduce social gap.A statement adopted at the conference urged governments to maintain international collaboration and promote equal access to healthcare regardless of wealth.Brazilian Health Minister Alexandre Padilha said the economic woes in many countries cannot be a reason to "diminish" their social policies."The crisis cannot be an obstacle, instead it must be an opportunity to consolidate social policies," he said.Brazilian Foreign Minister Antonio Patriota said at the conference that health was an issue related to sustainable development, which will be discussed at the UN's Rio +20 Conference in 2012."The conference that ended today is an important step toward Rio +20," he said.

OTTAWA, Oct. 3 (Xinhua) -- Many friends and colleagues of Canadian scientist Ralph Steinman reacted with shock when they learned on Monday that Steinman won the Nobel Prize for Medicine and Physiology three days after he died.Since 1974, Nobel Prizes are no longer awarded posthumously, but the Nobel Prize committee said that it had made its choice before Steinman's death.Many of Steinman's friends and colleagues said that they learned of Steinman's death at the same time that they learned of his Nobel Prize, which was awarded for a discovery Steinman made in 1973.Steinman, 68, discovered dendritic cells, which help regulate adaptive immunity, which purges invading microorganisms from the body. Dendritic cells activate T cells, which "remember" the DNA sequence of invading organisms and protect the body from later infections from the same disease."Their work has opened up new avenues for the development of prevention and therapy against infections, cancer and inflammatory disease," the citation said.Monday, the Nobel Committee defended its decision to award the prize to Steinman. "The decision to award the Nobel Prize to Ralph Steinman was made in good faith, based on the assumption that the Nobel Laureate was alive," the foundation said in a statement."The Nobel Foundation thus believes that what has occurred is more reminiscent of the example in the statutes concerning a person who has been named as a Nobel Laureate and has died before the actual Nobel Prize Award Ceremony."It is still unclear who will pick up Steinman's prize at the award ceremony later this year.Steinman, a cell biologist at Rockefeller University in New York City, died of pancreatic cancer on Friday. For more than four years, he had used his own immune therapy discoveries to extend his life."The news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago," Rockefeller University President Marc Tessier-Lavigne said in a statement."We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," Steinman's daughter, Alexis, said in the statement. "He devoted his life to his work and his family, and he would be truly honored."Steinman's heirs will share the 1.5-million U.S. dollar prize with American genetics professor Bruce Beutler and French scientist Jules Hoffmann.Dr. Beutler is professor of genetics and immunology at The Scripps Research Institute in La Jolla, California. Dr. Hoffmann headed a research laboratory in Strasbourg, France, between 1974 and 2009 and served as president of the French National Academy of Sciences between 2007 and 2008."Ralph worked right up until last week," said Michel Nussenzweig, a collaborator of Steinman's at Rockefeller University. "His dream was to use his discovery to cure cancer and infectious diseases like HIV and tuberculosis. It's a dream that's pretty close."Steinman was born in 1943 in Montreal, Canada's second largest city, and studied chemistry and biology at McGill University in his hometown before receiving an MD from Harvard Medical School in Boston in 1968. He joined Rockefeller University in 1970 as a postdoctoral fellow."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 university said in a statement.In a statement, Canadian Prime Minister Stephen Harper lauded the three winners of the Nobel for medicine and called the award " a fitting final tribute" to Steinman's life's work."Dr. Steinman shall be honored for all time with this achievement," Harper said. "Canadians will mourn his loss."

NEW YORK, Oct. 3 (Xinhua) -- For the 34-year-old Alexis Steinman, Oct. 3 would have been a great day, because her father Ralph Steinman was announced winner of the 2011 Nobel Prize in Physiology or Medicine.But as she talked to Xinhua at the Rockefeller University where his father worked, she said the day was rather "bittersweet"."This is the moment, but my Dad was not here," said Alexis, trying to hold her tears.The Canadian-born cell biologist Ralph Steinman died of pancreatic cancer on Friday at the age of 68, three days before he was announced the joint winner along with Prof. Bruce Beutler and Prof. Jules Hoffman for the Nobel Prize in Physiology or Medicine."We even talked about the Nobel Prize days before his death," Alexis added."We were like 'OK Dad, I know things aren't going well but the Nobel, they are going to announce it next Monday'. And he was like 'I know I have got to hold out for that. They don't give it to you if you have passed away,'" she said."It's really impossible to describe how our family is feeling right now. We're devastated to have lost Ralph,"Steinman' s son Adam Steinman told reporters at the press conference at Rockefeller University. "We're so incredibly proud of Dad for receiving this wonderful honor ... We know he will live on through his scientific contributions," he said.Rockefeller University president Marc Tessier-Lavigne told reporters during Monday's press conference that the university only heard of Steinman's death from the family about half an hour after news of the Nobel prize came out from Sweden."We are all deeply saddened by his death, " said Tessier- Lavigne , adding that Steinman had been treating himself with a groundbreaking therapy based on his research into the body's immune system.He said Steinman'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 people treat cancer, infectious diseases and disorders of the immune system.Steinman's first student and close colleague Michel Nussenzweig told the press conference packed with reporters, students and professors that "one of the interesting things about Ralph and his discovery is that no one believes it for a really long time.""What was amazing about Ralph was that he just knew that, even though nobody else believed it, this was really important, and he persisted, and finally after a very long time, everyone just found out it was true," Nussenzweig said."Ralph worked until last week. His dream was to use his discovery to make vaccines and it is a dream that is pretty close, and we are all continuing to work to make that come true," he added.The Nobel Foundation made a statement after learning Steinman's death, saying that the decision to award the prize to the Canadian scientist would remain unchanged despite his death, and the prize money will be transferred to his estate.

SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.
