BEIJING, Oct. 11 (Xinhuanet) -- An experimental drug that can remove amyloid plaques from the brains of Alzheimer's patients is being developed by Swiss Roche Holding AG in a small early-stage study, according to a report published in the Archives of Neurology on Monday.Researchers suspect the build-up of such plaques may be a cause of the memory robbing disease, although that theory has yet to be definitively proved. Gantenerumab, a biotech drug designed to bind to amyloid plaques in the brain and remove them, is being targeted at the early stages of Alzheimer's with the hope it can slow progression of the disease while patients are still able to function.The Phase I study of 16 Alzheimer's patients tested gantenerumab at two doses against a placebo over six months of treatment.The Roche drug led to a dose-dependent reduction of brain amyloid, while amyloid load increased in patients receiving a placebo, the report said.The next step will be to investigate whether removal of brain amyloid translates into clinical benefit for patients at doses of the experimental drug that are well tolerated and safe, the report said.Much larger trials and further study will be needed to fully understand how gantenerumab works and whether it can stave off Alzheimer's, said the report.Roche is approaching the disease far earlier because amyloid accumulates for 15 years before dementi.
WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."
ATHENS, Nov. 11 (Xinhua) -- The third Forum on the Development of Tibet concluded here on Friday after discussions on efforts to promote the world's understanding of Tibet and enhance the cooperation between China and the rest of the world with regards to Tibet's development.This year marks the 60th anniversary of Tibet's peaceful liberation. During the two-day event, delegates from Greece, Britain, France, Germany, India and Nepal expressed their opinions on Tibet's modernization and put forward valuable advice and suggestions based on their own experience and research findings.Some of the foreign delegates have visited Tibet many times before. Narasimhan Ram, Editor-in-chief of The Hindu from India and Brendan O'Neill, editor of the British magazine Spiked spoke positively about the preferential polices and financial support of the Chinese central government and other parts of China for the region.During the Forum, Wang Chen, head of the Chinese State Council Information Office met with the Greek political leaders and journalists from mainstream media.People got an opportunity to learn more about China as Nyima Tsering, Vice Chairman of the Standing Committee of the People's Congress of the Tibet Autonomous Region, introduced the development of Tibet and the Chinese government's policy towards the region.A number of Greek mainstream media covered the Forum.Over the past 60 years, Tibet has achieved a huge development in both its social structure and socio-economic development, said a communique released upon the end of the forum.It also foresees a great potential of cooperation with the international community in energy, environment, education and healthcare development for the region.The forum has facilitated better understanding of Tibet in the international community and will help to promote faster and better development of the autonomous region, the Communique said.
ISLAMABAD, Oct. 24 (Xinhua) -- Samina, 38, was shocked when doctor told her that she has been suffering from breast cancer for three years and due to late diagnosis the disease spread into her bones making the chances of survival very slim.Samina said that she is trying hard to fight the disease, at the same time she holds the doctors of her village responsible for failing to diagnose the disease in three long years. She is also concerned about her three kids too young to accept any bitter reality."I can't see the distressed faces of my children, I can't bear the fear that looms in their eyes, they know that with every coming day their mother is moving a step forward to death," Samina told Xinhua in a very low tone.When Samina and all other patients of that gloomy medical ward for breast cancer patients, in Nuclear Medicine Oncology and Radiography (NORI) hospital in Islamabad, were told that October is being observed as breast cancer awareness month they murmured that the awareness message should be reached to every nook and corner of the country this year so that no other woman would die due to unawareness.In a country like Pakistan where one in nine women is prone to breast cancer and around 40,000 women die every year due to lack of awareness of this disease. They come to visit oncology department of hospitals at a stage when the chances of survival are very remote.Omer Aftab, National Coordinator of the Pink Ribbon, said that Pakistan has the highest rate of breast cancer among Asian nations. It is the most common malignancy in women, and accounts for 38.5 percent of all female cancer patients, with 90,000 new cases every year.
TEHRAN, Oct. 9 (Xinhua) -- Iran is going to launch domestically- built Navid satellite by Safir satellite launcher by the end of March 2012, the semi-official Mehr news agency reported on Sunday.Navid (promise) is a research satellite and is currently undergoing pre-launch tests, said the report without further details.In June, Iran put the Rasad (surveillance) satellite in the orbit to render images to the country.Iran put a satellite into orbit in 2009 and sent some small animals into space in 2010.
