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, Nov. 22 (Xinhuanet) -- Underweight patients may have more possibilities of mortality within 30 days of general and vascular surgery compared with mildly obese patients, according to a research published online in Archives of Surgery Tuesday.Researchers at the U.S. National Surgical Quality Improvement Program conducted the research for the years 2005 and 2006, and assessed the contribution of BMI (Body Mass Index) to 189,533 postsurgeries morbidity and mortality by obesity classes.They found that compared with the middle BMI quintile group, patients with BMI value below 23.1, had greater chances for death. For the highest BMI quintile group, higher mortality rate was also observed.However, the researchers also found that obesity may as well be associated with increased mortality for some individual types of surgeries."These individual types of procedures include procedures with which the general surgeon should have definite experience: colorectal resection, colostomy formation, cholecystectomy, hernia repair, mastectomy, and wound debridement," said George J. Stukenborg, PhD, of the University of Virginia inCharlottesvilleand his colleagues.Based on a 30 –day morbidity and mortality risk calculation, the sample patients were categorized into BMI quintile ranges. BMI value of less than 23.1 was considered as lowest, values from 26.3 to 29.6 considered as the middle quintile, and above 35.2 considered as the highest.Factors such as lack of enough data on nonfatal complications and hospital resources, or examining mortality over the 30-day baseline, may cause limitations and inaccuracy to the research and more studies on a wider range of patients in terms of BMI are needed to further confirm the current conclusion, researchers said.

SEOUL, Jan. 6 (Xinhua) -- LG Electronics, the world's No.2 TV maker, said Friday that it will showcase a smart TV that runs Google TV during next week's Consumer Electronics Show (CES) in Las Vegas.The LG-made Google TV powered by Google's Android operating system (OS) will be unveiled next Monday at the U.S. consumer electronics fair in Las Vegas, according to an e-mailed statement by LG.The Internet TV will offer its Android-based user interface, enabling consumers to enjoy web browsing and social networking, LG said. Multi-taking will also be available as the Internet surfing, social networking and TV functions can be run simultaneously.LG's three-dimensional (3D) technology will be available through its Google TV. With a single click of a remote controller, any two-dimensional (2D) program or movie can be viewed in 3D due to the built-in 2D to 3D conversion engine."Through Google TV, LG has merged Google's established Android operating system with LG's proven 3D and Smart TV technologies, offering consumers a new and enthralling TV experience," said Havis Kwon, chief executive of LG Electronics' home entertainment business.

SAN FRANCISCO, Nov. 14 (Xinhua) -- Google is running a secret research lab in the San Francisco Bay Area, where the tech giant invests to experiment and invent what may be world-changing technologies for the future, U.S. media reported on Monday.According to The New York Times, at the lab dubbed Google X, engineers are working at some 100 projects from robots, smart refrigerators to Internet-enabled dinner plates and a "space elevator," a proposed non-rocket space launch structure.An unnamed Google engineer familiar with the lab told the newspaper that it was run as mysteriously as the CIA with two officers, a nondescript one for logistics on the company's Mountain View campus and one for robots in a secret location.Scientists working at the lab include many roboticists and electrical engineers hired from Microsoft, Nokia labs, Stanford, MIT, Carnegie Mellon and New York University. Google's co-founder Sergey Brin is said to be "deeply involved" in Google X.The lab is reportedly headed by Sebastian Thrun, one of the world's top robotics and artificial intelligence experts. He teaches computer science at Stanford University and invented the world's first self-driving car.A Google spokeswoman would not confirm the existence of the lab, but said Google likes to invest in speculative projects."While the possibilities are incredibly exciting, please do keep in mind that the sums involved are very small by comparison to the investments we make in our core businesses," she told The New York Times.

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.
