    Real Madrid top Forbes' most valuable soccer teams list

    REUTERS - European champions Real Madrid are the world's most valuable soccer club for a third straight year, according to a Forbes poll released on Wednesday that showed the average value of the top 20 teams rose 11 percent over last year. The Spanish club's value fell five percent to $3.26 billion but their $746 million in revenue, the highest of any sports team in the world, was enough to keep them top of the list, Forbes said in a statement.

    Striking deficiencies giving Van Gaal much to ponder

    By Martyn Herman LONDON (Reuters) - Manchester United manager Louis van Gaal accepts that finding a cure for his side's misfiring forward line will be essential if they are to challenge for the Premier League title next season. United's steady improvement under the Dutchman has come to a grinding halt with consecutive defeats against Chelsea, Everton and West Bromwich Albion, undermining their hopes of sealing a top-four finish without undue anxiety. They failed to score in any of those …

    Chelsea's title built on granite foundations

    By Mitch Phillips LONDON (Reuters) - While some of his rivals were spending millions on marquee defenders last summer Jose Mourinho was happy to sell David Luiz secure in the knowledge he had a back four that would be the bedrock of Chelsea's title push. With the Premier League trophy now back at Stamford Bridge, Mourinho's judgement has again proved spot on as John Terry, Gary Cahill, Branislav Ivanovic and Cesar Azpilicueta have been the most reliable defensive unit in the country. Marcos …

    By Tom Hayward LONDON (Reuters) - Burnley and Queens Park Rangers' Premier League survival hopes were left hanging by a thread after defeats and unfavourable results elsewhere left them rooted to the foot of the table on Saturday. Manchester United slipped to a third successive defeat, 1-0 at home to West Bromwich Albion, at the other end of the league and missed the chance to go second behind Chelsea who can lift the title on Sunday by beating Crystal Palace at Stamford Bridge.

    Juventus bring out the best in rejuvenated Tevez

    Carlos Tevez arrived at Juventus with a reputation as a troublemaker who had fallen out of favour both at his former club Manchester City and the Argentine national side. Juve have tamed the wilder instincts of a player who was once sent off for Boca Juniors in his homeland after celebrating a goal against River Plate by flapping his arms to imitate a chicken. The 31-year-old scored 21 goals in his first season as Juventus won Serie A by a 17-point margin and has been instrumental in helping …

Washington, March 13 (IANS) A new study has found that stem cells from the patient's own body fat could help seek out and destroy cancer cells in a type of brain tumour.

Johns Hopkins researchers say they have found the stem cells from body fat may have the potential to deliver new treatments directly into the brain after the surgical removal of a glioblastoma, the most common and aggressive form of brain tumour.

According to investigators, the mesenchymal stem cells (MSCs) have an unexplained ability to seek out damaged cells, such as those involved in cancer, and may provide clinicians a new tool for accessing difficult-to-reach parts of the brain where cancer cells can hide and proliferate anew.

The researchers say harvesting MSCs from fat is less invasive and less expensive than getting them from bone marrow, a more commonly studied method, reports Science Daily.

Results of the Johns Hopkins proof-of-principle study are described online in the journal PLOS ONE.

"The biggest challenge in brain cancer is the migration of cancer cells. Even when we remove the tumour, some of the cells have already slipped away and are causing damage somewhere else," says study leader Alfredo Quinones-Hinojosa, professor of neurosurgery, oncology and neuroscience at the Johns Hopkins University School of Medicine.

"Building off our findings, we may be able to find a way to arm a patient's own healthy cells with the treatment needed to chase down those cancer cells and destroy them. It's truly personalised medicine," adds Quinones-Hinojosa.
