ALMATY, Nov. 4 (Xinhua) -- Kazakhstan's Center for Prevention and Control of AIDS said Friday that the country had 17,266 registered HIV carriers as of Oct. 1,compared with 15,908 as of Feb. 1, 2010.Of the HIV-positive people, 1,432 were diagnosed with AIDS while 1,110 people carrying the virus AIDS have died, the center said.Last year, it said, a total of 1,969 new HIV cases were reported in the country.

BEIJING, Nov. 28 (Xinhuanet) -- Scientists in Canada have raised a prospect of reversing Alzheimer's disease by deep brain stimulation, according to media reports Monday.The technique here is known as deep brain stimulation -- applying electricity directly to regions of the brain. It has been used in tens of thousands of patients with Parkinson's as well as having an emerging role in Tourette's Syndrome and depression.The study at the University of Toronto took six patients with the condition. Deep brain stimulation was applied to the fornix -- a part of the brain which passes messages onto the hippocampus.Lead researcher Prof Andres Lozano said you would expect the hippocampus to shrink by five per cent on average in a year in patients with Alzheimer's.After 12 months of stimulation, he said one patient had a five per cent increase and another had an eight per cent increase.Prof Lozano told BBC: "This is the first time that brain stimulation in a human being has been shown to grow an area of your brain.""It was an amazing finding for us," he said.The findings were presented at the Society for Neuroscience conference in November but they have yet to be published in an academic journal.To test whether this is really working, rather than being a fluke result, the researchers are going to perform a larger trial.

BEIJING, Dec. 30 (Xinhua) -- China will push to properly resolve the case of a Chinese skipper indicted by Japan, the Foreign Ministry said Friday.Spokesman Hong Lei said this is a common fishing case, and the Chinese embassy in Japan has dispatched officials to visit the skipper.China requests that Japan ensure the rights of the Chinese skipper, Hong said, and China is communicating closely with Japan in order to properly resolve the case.The Chinese government has been requiring fishermen to fish legally, Hong said, adding that the competent authorities have done a lot in this area, and he promised to promote the management and education of Chinese fishermen.Japanese prosecutors have indicted the captain of a Chinese fishing boat for illegally operating in Japanese waters, a local official said Friday.The Nagasaki District Public Prosecutors Office has finalized its case against Zhong Jinyin, 39, following his December 20 arrest near islands off southwest Japan, according to the official.The prosecutors have not indicated whether the skipper has admitted to the charge.

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."

WASHINGTON, Oct. 3 (Xinhua) -- The Rockefeller University confirmed Monday its Canadian-born cell biologist Ralph Steinman died three days before being awarded the Nobel Prize on Monday as the Nobel committee was unaware of his death at the time."Steinman passed away on September 30," the New York university said in a statement."He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design."The Nobel committee was unaware of Steinman's death when announcing this year's winners and it was unclear whether the prize would be rescinded because Nobel statutes don't allow posthumous award."The Rockefeller University is delighted that the Nobel Foundation has recognized Ralph Steinman for his seminal discoveries concerning the body's immune responses," says Rockefeller University President Marc Tessier-Lavigne."But the news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago after a long battle with cancer. Our thoughts are with Ralph's wife, children and family.""We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," says Steinman's daughter Alexis. "He devoted his life to his work and his family, and he would be truly honored.""Ralph's research has laid the foundation for numerous discoveries in the critically important field of immunology, and it has led to innovative new approaches in how we treat cancer, infectious diseases and disorders of the immune system," Tessier-Lavigne says.Steinman, who discovered the immune system's sentinel dendritic cells, is this year's recipient of the Nobel Prize in Physiology or Medicine. He shares half the prize with Bruce Beutler and Jules Hoffmann.
