WASHINGTON, March 22 (Xinhua) -- A long-term study by Greek researchers has shown the effectiveness of replacing bone marrow, purposely destroyed by chemotherapy, with autologous (self) stem cells in treating people with aggressive forms of multiple sclerosis (MS).The study was published on Tuesday in Neurology, the medical journal of the American Academy of Neurology.For the treatment, chemotherapy drugs are used to kill all of the patient's blood cells, including the immune cells that are believed to be attacking the body's own central nervous system. Bone marrow stem cells removed from the patient are purified and transplanted back into the body, which saves life by replacing the blood cells and also is proposed to "reboot" the immune system.A human embryonic stem cell line derived at Stanford University is seen in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009The study followed 35 people for an average of 11 years after transplant. The study involved people with rapidly progressive MS who had tried a number of other treatments for MS with little or no effect. All were severely disabled by the disease, with an average score of six on a scale of disease activity that ranges from zero being a normal neurological examination to 10 meaning death due to MS.A score of six means able to walk with a cane or crutch; a seven is mainly in a wheelchair. All had worsened by at least one point on the scale in the year prior to the transplant.After the transplants, the probability of participants having no worsening of their disease for 15 years was 25 percent. The probability was higher -- 44 percent -- for those who had active brain lesions, which are a sign of disease activity, at the time of the transplant.For 16 people, symptoms improved by an average of one point on the scale after the transplant, and the improvements lasted for an average of two years. The participants also had a reduction in the number and size of lesions in their brains. Two people (six percent) died from complications related to the transplant at two months and 2-1/2 years post-transplant.Study author Vasilios Kimiskidis, of Aristotle University in Thessaloniki, Greece, noted that more research is needed on this treatment, including studies that compare people receiving the treatment to a control group that does not receive the treatment."Keeping that in mind, our feeling is that stem cell transplants may benefit people with rapidly progressive MS," he said. "This is not a therapy for the general population of people with MS but should be reserved for aggressive cases that are still in the inflammatory phase of the disease."

BEIJING, May 24 (Xinhuanet) -- Facebook founder Mark Zuckerberg welcomed more kids to join in the social network site, according to International Business Times reports on Monday.He made this comment in the NewSchools Summit in California.Zuckerberg said Facebood can help young kids to learn from each other and acquire more knowledge about using the internet."That will be a fight we take on at some point," Zuckerberg said, "My philosophy is that for education you need to start at a really, really young age." At the moment, Facebook officially does not allow the children younger than 13 to sign up, since the Children's Online Privacy Protection Act (COPPA) forbids children under 13 from joining an online service which collects user information data.However it recently revealed that 7.5 million Facebook users were younger than that, accoding to a study released last week by Consumer Reports.Some experts suggested Facebook may not be in any position to provide that education in its current form. "The lessons of digital citizenship have to start young, but I don't feel that Facebook is the venue to have those lessons occur. A lot of missteps happen on that site without a lot of coaching." said Dr. Gwenn O'Keeffe, an expert on young children's education.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.
