LOS ANGELES, April 2 (Xinhua) -- The United States could soon be faced with an epidemic of Non-Alcoholic Fatty Liver Disease ( NAFLD), one of the major contributing factors of chronic liver disease (CLD), the American Association for the Advancement of Science (AAAS) reported Saturday.If the current rates of obesity and diabetes continue for another two decades, the prevalence of NAFLD in the U.S. is expected to increase by 50 percent in 2030, AAAS said.The prediction is based on pre-existing clinical survey data over a 10 year period (1988-1994, 1999-2004 and 2005-2008), which included 39,500 adults from three survey cycles, according to the AAAS.Over the three cycles, the prevalence of NAFLD doubled from 5. 51 percent to 11 percent respectively. Furthermore, during the first survey cycle (1988-1994) 46.8 percent of all CLD's was related to NAFLD but by 2005-2008 this had increased to 75.1 percent. In addition, the prevalence of obesity and diabetes, the two key risk factors for NAFLD also steadily increased."If the obesity epidemic is anything to go by, the U.S. NAFLD epidemic may have a ripple effect worldwide," said Mark Thursz, Vice Secretary of the European Association for the Study of the Liver. "It is imperative that health systems continue to drive effective educational programs to reinforce awareness among the general public to alert them of the risks of obesity and promote the importance of diet and exercise."Non-alcoholic fatty liver disease is fast becoming one of the top concerns for clinicians due to the obesity epidemic and it's potential to progress to advanced liver disease which significantly impacts on overall liver-related mortality, Thursz said in remarks published by AAAS' website EurekAlert.org.NAFLD, considered as one of the major causes of morbidity and mortality worldwide, is the term used to describe fat build-up in liver cells in people who do not drink alcohol excessively. The disease is the most common persistent liver disorder in Western countries with an estimated overall prevalence of 20-30 percent, according to AAAS.NAFLD encompasses a spectrum of liver disease associated with insulin resistance, diabetes and obesity and as such people most at risk of NAFLD are those who are obese, have insulin resistance associated with diabetes, high blood pressure and cholesterol.

SAN FRANCISCO, March 29 (Xinhua) -- Amazon.com Inc. on Tuesday announced the launch of an on-line music storage service,which enables users to store digital music in the cloud and access it from computers and devices running Google's Android operating system.The new service, called "Cloud Drive," offered customers five gigabytes of free storage on Amazon Web servers for all kinds of digital files, including music, photos, videos and documents. For paid plans, users can purchase storage space starting at 20 U.S. dollars a year for 20 gigabytes.The on-line retailer also launched "Cloud Player for Web" and " Cloud Player for Android." The former allows users to get the media files they stored on Amazon's servers from a Web browser on a Mac or PC. The latter lets users play music they have uploaded on Cloud Drive, computers or a smartphone that runs Android operating system.Analysts said Amazon is stepping up its rivalries with Apple and Google. Both companies are also working on similar services, allowing users to store their music on-line and access it from any compatible device.Media reports said that Apple was pushing hard to launch a digital music locker service in April. Google was also reported to be testing its own digital locker service but it still needs to make agreements with major music labels.

SINGAPORE, April 21 (Xinhua) -- Singapore's first locally-built satellite has been officially launched from a space center in India after a four-year delay, Singapore media reported on Thursday.The 105 kg fridge-size X-Sat was one of three riding on Isro's Polar Satellite Launch Vehicle (PSLV-C16) from the Satish Dhawan Space Center in India on Wednesday. It will be used to take photographs to measure soil erosion and environmental changes on earth, local daily Straits Times said.The launch at 12:42 p.m. on Wednesday was the 18th successful lift-off since the maiden flight of PSLV in 1994.The satellite was designed and built by Singapore's Nanyang Technological University and Singapore's defense research body DSO National Laboratories.Now in orbit, the satellite is establishing communication contact with the ground control in Nanyang Technological University, a process that is likely to take up to a week.The launch capped more than nine years of hard work by scientists and engineers. It also makes Singapore one of the first countries in Southeast Asia to have its own satellite in space. Previous satellite launched by Singapore involved construction efforts by foreign companies.

BEIJING, Jan. 30 (Xinhua) -- As of Jan. 28, 77.4 million mu (5.16 million acres) of crops had been harmed by the ongoing drought, and 2.57 million people were faced with drinking water shortages in China, the national drought control authorities said Sunday.Local governments of the affected regions must make efforts to monitor drought conditions, speed up the building of water projects, increase drought-fighting material reserves and grant subsidies to the drought-stricken population, said officials at a meeting attended by Chen Lei, deputy head of the Office of State Flood Control and Drought Relief Headquarters (SFDH).The National Meteorological Center (NMC) forecast the drought to worsen in the next two months, saying Sunday that the drought-hit north China and regions along the Yellow and Huaihe rivers would receive little rain or snow in February and March.Chen, also minister of water resources, stressed the importance of drought relief efforts, guaranteeing agricultural production and ensuring drinking water safety for boosting consumers' confidence, controlling consumer prices and inflation and maintaining economic growth.Since last Autumn when the drought began, local authorities have assigned 9.55 million people and 2.15 million sets of drought-fighting machineries to draw 8.2 billion cubic meters of water to irrigate 110 million mu of crop land.
