WASHINGTON, Nov. 16 (Xinhua) -- Supervised exercise was shown to be more effective than stenting or medication for improved walking ability in patients with peripheral artery disease (PAD), according to a U.S. study reported Wednesday at the 2011 American Heart Association Scientific Sessions meeting.The research group reported that of 111 patients studied in the randomized trial, the most effective treatment proved to be supervised exercise based on the results of a treadmill test taken at baseline and again at six months. Patients who were in the supervised exercise group improved by a mean of 4.6 minutes in the treadmill test, while the group who received stents improved by a mean of 2.5 minutes. However, researchers found that self-reported quality of life measurements proved to be higher in the group that received stents, even though their ability to walk did not improve as greatly as the group that received supervised exercise rehabilitation.The findings were published in the November issue of the journal Circulation. The researchers believe that more studies are necessary, although supervised exercise may be an effective treatment recommended for PAD patients with claudication.PAD is a condition in which plaque builds up in the arteries and affects blood flow, especially to the legs. It is estimated that between 10 and 12 million people suffer from PAD in the United States. One symptom of PAD is known as claudication, a painful cramping of the leg muscles that limits the patient's ability to walk. It affects nearly 2 million people who suffer from PAD, and results in a sedentary lifestyle and poor quality of life.Current U.S. guidelines for the treatment of claudication include pharmacotherapy, supervised exercise rehabilitation and lower extremity revascularization using stents.

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.

BEIJING, Nov. 26 (Xinhua) -- Joint police patrols along the Mekong River will kick off in mid December to restore security after a deadly attack to Chinese ships in October.Chinese police will start patrols along the river with Laos, Myanmar and Thailand, said a statement from the Ministry of Public Security here Saturday.No exact date was given, but the first joint patrol will be carried out before Dec. 15, said the statement, issued after a ministerial meeting of four countries held in Beijing.Police from the four will work together to restore shipping and guarantee security along the river, the statement said.Shipping on the Mekong River has been suspended since two cargo ships were attacked on Oct. 5, resulting in the murder of 13 Chinese sailors.A headquarters for the initiative will be founded in China and there will be a coordination office in each of the other three countries. They will be linked by a round-the-clock communication mechanism, the statement said.China will assist Laos and Myanmar police in terms of training and equipment, the statement said.Police departments of the four countries will also set up a coordination team to work out more security measures along the Mekong River, it added.

WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.

BEIJING, Dec. 11 (Xinhua) -- A draft regulation on school bus safety management was made public Sunday by the Legislative Affairs Office of the State Council, with the public invited to submit comments on it.The draft stipulates that local governments above the county level should take "overall responsibility" in school bus safety, and authorities of education, public security, transportation and product quality supervision should also properly perform their respective duties.The government will establish and improve a system of mandatory technical standards for the quality of vehicles used as school buses, the draft stated. Primary school students queue up to get on the school bus to go home after school in Deqing County, east China's Zhejiang Province, Nov. 21, 2011. Local government of Deqing County has invested 20 million yuan (3.14 million U.S. dollars) to order 79 school buses, which are specially designed for children with smaller seats and seat belts as well as bright yellow color to have better warning function. Among the 79 buses, 14 ones have truck-style front ends, and this appearance like a long nose can effectively reduce the impact force and better protect children's safety. Drivers of such kind of school buses are required not to exceed 60 kilometers per hour. Nearly 6,000 children from 25 primary schools have benefited from the operation of this kind of school bus in Deqing County.China issued a set of technical standards for school buses for primary school students last year, and the drafting of another standard for buses for the kindergartners is also underway.According to the draft, the government will adopt a license system for school bus operation.Vehicles that are up to school bus standards and with a unified appearance will be first in line to obtain approval from education authorities, and the draft also requires buses to register at the traffic administrative agencies before they can be used as school buses.Instead of compulsory annual safety checks, the draft would require school bus owners to renew their safety qualifications every six months.Drivers should also check the safety condition of the buses before each commute, the draft said.The draft asks schools and the school bus service providers to intensify safety management and maintenance and assign special staff on buses to look after students on board.
