BEIJING Cheap Men's Nike Vapormax Collegiate Navy Black UK , Aug. 19 (Xinhua) -- Pole vault legend Sergey Bubka of Ukraine has pledged his total commitment to the IAAF and athletics family after losing the election for the new president of the IAAF.


Bubka was defeated 92-115 by Sebastian Coe of Britain in a vote held at the IAAF Congress here on Wednesday and received 187 votes to continue in his role as IAAF vice president.


"First of all, I would like to congratulate Seb Coe on his campaign, which gave us great opportunities to discuss many challenges of our sport, communicate with our Member Federations, and share our vision for the future of athletics Cheap Air VaporMax Men's Nike Shoes Pure Platinum White UK ," said Bubka.


"From the very bottom of my heart, I would like to thank the Member Federations, who voted for my candidacy as IAAF President as well as for my Vice-Presidency role. Thanks a lot to my family and my team who supported and assisted me throughout all these months - we've done a fantastic job together."


"I will continue to serve athletics as I've done during all my life in any position our Athletics family trusts me to hold. I wish good luck to the new IAAF President and remain committed to the ideas and proposals I delivered throughout my campaign," he added.


CHICAGO, Nov. 28 (Xinhua) -- Researchers at the University of Illinois (UI) are trying to use tiny drug-laden nanoparticles to seek and destroy cancer stem cells.


They used the nanoparticles to deliver niclosamide that targets a protein called CD44 only appearing on the surface of cancer stem cells Cheap Men's Nike Vapormax Pale Grey Ice Blue UK , and found the cancer stem cells lost their stemlike properties after treatment with the niclosamide-bearing targeted nanoparticles, and are less able to cause the cancer to recur or metastasize.


The researchers also detected a significant decrease in overall cancer cell growth, both in the cell cultures and in the mice, according to a report released Monday on the UI website.


"I call them 'GPS-enabled nanoparticles,' because they seek out only the cells that have cancer stem cell properties. Then they latch onto the cells and deliver the drug Cheap Men's Nike Air Max 97 Carbon Grey White UK ," said Dipanjan Pan, a UI professor of bioengineering. "To the best of our knowledge, this is the first demonstration of delivering cancer stem-cell-targeted therapy with a nanoparticle."


Cancer stem cells represent a tiny fraction of cells in a tumor, but it only takes one or two to seed a new tumor, Pan said. The challenge for physicians and researchers is not only finding these cells Cheap Men's Nike Air Max 97 Black Red UK , but treating them.


Previous study found that niclosamide works on a particular gene-regulation pathway in cancer stem cells. Niclosamide is on the World Health Organization's List of Essential Medicines, which is an index of the safest and most effective drugs in the world, and is a drug commonly prescribed to treat tapeworm infections.


"This work is important to future researchers working in the field of cancer stem cells," said postdoctoral researcher Santosh Misra, the first author of the study. "We described and confirmed the proteins and genes responsible for vital processes in these cells Cheap Women's Nike Air Max 97 GS Purple White UK , and that is opening up new avenues to make better therapies."


UI researchers are now working to create a combination therapy that can deliver drugs for the primary cancer, such as traditional chemotherapies, as well as targeted agents that can treat cancer stem cells. They are also testing the nanoparticle drug-delivery system in large animal models to bring it a step closer to the clinic.


The study has been published in the journal Molecular Cancer Therapeutics.

As a young man Cheap Women's Nike Air Max 97 Coral Light Pink UK , Bidhan Kamol Rosario left his Catholic village to fight for Bangladesh's independence. Now he questions his future in the country after a rise in Islamist extremism that has left minorities living in fear.


As Bangladesh's small Catholic community eagerly awaits the first visit by a pope in more than 30 years, many say it has never been more difficult to practice their faith in the Muslim-majority country.


Christian leaders say many have left Bangladesh in recent years as the community increasingly finds itself targeted by Islamists.


Last year, two converts from Islam were murdered and a Catholic grocer brutally hacked to death during a campaign by Islamist extremists that also targeted Hindus and other minorities.


"In the War of Liberation, we wanted a beautiful Bangladesh which embraced all types of people from all races, faiths Cheap Men's NikeLab Air Max 97 Mid Boots Triple Black Rainbow UK , creeds and religions," said Rosario, 65, of the 1971 war that brought independence for the former East Pakistan.


"I never wanted advantages or favors for myself, only that there be equal rights for all... But now I do not believe there is any equality for us."


From peace to peril


Christians make up less than 0.5 percent of Bangladesh's 160 million-strong population Cheap NikeLab Air Max 97 Mid Boots Triple White Rainbow UK , but once lived for centuries in harmony with the local Muslim majority.


They have played a prominent role in the country's history and even today, schools and hospitals run by Catholic missionaries provide a lifeline for poor communities.


Rosario is part of a small Catholic community descended from Portuguese traders who settled in Nagori, a small cluster of villages near the capital Dhaka, in the 17th century.


The area remains a bulwark of Catholicism and is home to a small shrine where hundreds of thousands gather every February to celebrate the life of Saint Anthony.


Local Catholics there say they feel increasingly under threat after a spate of attacks by hardline Islamists targeting religious minorities, foreigners and secular bloggers.


Tensions with Bangladeshi authorities have also risen Cheap Men's Nike Air Max 97 OG GS Army Green Black UK , they say, boiling over in March when villagers accused plain clothes police of raiding the home of a local widow and stealing money.
