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.

BEIJING, Jan. 5 (Xinhua) -- The U.S. Secretary of Treasury Timothy Geithner will visit China from Jan. 10 to 11 as a special representative of the U.S. President Barack Obama, Chinese Foreign Ministry spokesman Hong Lei announced on Thursday.Timothy Geithner's visit is at the invitation of Chinese Vice Premier Wang Qishan, said Hong.Chinese top leaders will meet with Timothy Geithner and exchange views with him on issues concerning Sino-US economical relations and the world's economic and financial situations, Hong said.

JERUSALEM, Nov. 1 (Xinhua) -- Israeli researchers at Tel Aviv University developed a computer chip that could recuperate loss body movement if placed in the cerebellum, opening the doors to treatment of brain damage, researchers told Xinhua on Tuesday.The computer chip, wired to a man-made segment of a cerebellum, was attached to a rodent's skull that had lost the ability to blink. After the artificial cerebellum was implanted, the rodent was once again able to blink.The chip, connected to the rat's brain, works by reading sensory information from the body and then communicating it to the cerebellum, the area of the brain that allows movement coordination, through electrodes."The chip itself imitates a small part of the cerebellum, a very tiny part of it," said Prof. Matti Mintz of TAU's Department of Psychology."We took a small part of the cerebellum and studied it and created the computer chip that mimics the damaged area," he said.However, more complicated movements, like walking, are still at least one decade away, Mintz added."We still did not test it on humans because we need to know the area the chip will mimic before installing it, which requires extensive research. But we are now developing a chip that will do a sequence of simple movements," he pointed out.When fully developed for humans, it can be used to help patients who suffer brain genetic diseases like Parkinson, or had strokes that caused brain damage.

TOKYO, Jan. 24 (Xinhua) -- Japanese Foreign Minister Koichiro Gemba said Tuesday that Japan will seek to take a less inward- looking stance when it comes to diplomacy in the Asia-Pacific region.Specifically he said that Japan will look to enhance diplomatic ties with China based on mutually beneficial goals."With China, this year marks the 40th anniversary of normalizing diplomatic ties. We will aim to deepen the mutually beneficial relationship based on common strategic interests," Gemba said Tuesday in his first foreign policy speech in parliament.He went on to say that Japan plans to proactively make " concrete efforts" to strengthen its ties with China and establish more "open and multilayered networks" in the best interests of both countries.
